What CPA REG is really testing

CPA REG rewards candidates who can apply tax authority and business-law rules to specific taxpayer facts. Strong answers identify taxpayer type, timing, basis, character, limitation, authority level, and required action before selecting the result.

High-yield CPA REG traps

  • mixing taxpayer penalties with preparer penalties or practitioner discipline
  • forgetting basis, holding period, character, or limitation rules before computing a tax effect
  • confusing individual, entity, and owner-level tax consequences
  • using business-law labels without checking the legal relationship in the facts

Simulation-style skills to pair with MCQs

Use multiple-choice practice to test rule selection, then pair it with document-style tax and law review. For CPA REG, that means reading short taxpayer facts, entity details, property-basis facts, filing-status clues, penalty notices, and contract or agency scenarios before deciding the consequence. When you miss an MCQ, mark whether the weakness was taxpayer identification, timing, basis, character, limitation, authority, or legal relationship.

How to use CPA REG practice efficiently

  1. Start with focused topic drills until you can explain the rule, objective, or calculation setup behind each answer.
  2. Use the free 72-question diagnostic once as a baseline rather than as a memorization set.
  3. Review misses by weakness type and return to the matching topic page before another timed set.
  4. Move into timed mixed practice when topic-level accuracy is stable and you need pacing discipline.
  5. If several unseen timed attempts are above roughly 75%, schedule or proceed instead of trying to memorize the full bank.

Question 1

Topic: Federal Taxation of Property Transactions

A calendar-year corporation is reviewing its current-year tax depreciation schedule. All assets shown are 7-year MACRS personal property, no property is listed property, the corporation elected out of bonus depreciation, and no Section 179 deduction was elected. The tax department’s reminder states that if more than 40% of the basis of depreciable personal property placed in service during the year is placed in service in the last quarter, the mid-quarter convention applies to all covered personal property placed in service that year. Round each line to the nearest dollar.

Relevant first-year rates:

Convention and quarterRate
Half-year14.29%
Mid-quarter, Q125.00%
Mid-quarter, Q310.71%
Mid-quarter, Q43.57%

Depreciation schedule under review:

AssetCostPlaced in serviceRate usedDepreciation claimed
Production equipment$140,000March 1014.29%$20,006
Office furniture$50,000September 1514.29%$7,145
Packaging line$210,000November 2014.29%$30,009
Total$400,000$57,160

Which interpretation is best?

  • A. The schedule includes all three assets but overstates current-year depreciation by $9,308 because the mid-quarter convention applies to all three assets.
  • B. The schedule is complete and accurate because each asset is 7-year property and the half-year rate is the applicable first-year rate.
  • C. The schedule overstates current-year depreciation by $22,512 because the mid-quarter convention applies only to the asset placed in service in Q4.
  • D. The schedule is incomplete because the asset placed in service in Q4 cannot be depreciated until the following tax year.

Best answer: A

Explanation: The cost-recovery schedule includes each asset from the source data, so the issue is accuracy rather than completeness. Because more than 40% of the personal property basis was placed in service in the last quarter, the schedule should use mid-quarter rates for all three assets. The last-quarter test compares Q4 placed-in-service basis with total covered personal property basis placed in service during the year. Here, the packaging line placed in service in Q4 has $210,000 of basis, which is 52.5% of the $400,000 total. Because that exceeds 40%, the mid-quarter convention replaces the half-year convention for all three assets. Correct depreciation is \(140,000 × 25.00% =\)35,000, plus \(50,000 × 10.71% =\)5,355, plus \(210,000 × 3.57% =\)7,497, for a total of $47,852. The schedule claimed $57,160, so current-year depreciation is overstated by $9,308.


Question 2

Topic: Ethics, Professional Responsibilities and Federal Tax Procedures

A CPA represents an individual taxpayer in an IRS income tax examination. The CPA concludes that the IRS has moved from information gathering to proposed adjustments, and that the taxpayer’s next response option is to request an administrative Appeals conference by a timely written protest rather than immediately paying the tax or petitioning Tax Court. Which item in the file best supports that conclusion?

  • A. A statutory notice of deficiency stating that the taxpayer has 90 days to petition the U.S. Tax Court
  • B. An initial IRS examination appointment letter identifying the return selected for audit and asking the taxpayer to contact the examiner
  • C. An IRS 30-day letter enclosing the examination report of proposed changes and stating that the taxpayer may request an Appeals conference by submitting a written protest within 30 days
  • D. A Form 4564 Information Document Request asking the taxpayer to provide bank statements, invoices, and mileage logs by a specified date

Best answer: C

Explanation: The 30-day letter is issued after the examiner proposes adjustments and gives the taxpayer an opportunity to seek administrative review. It supports the conclusion that the case is at the proposed-adjustment stage and that a timely protest can preserve access to IRS Appeals. In a typical IRS examination, the taxpayer first receives an audit contact or appointment notice. The examiner then may issue Information Document Requests to gather support. After reviewing the facts, the IRS may issue a proposed examination report with a 30-day letter, giving the taxpayer the option to agree or disagree and request an Appeals conference. A statutory notice of deficiency comes later if the disagreement is not resolved and gives the taxpayer the right to petition Tax Court before assessment.


Question 3

Topic: Business Law

Marlow, Inc. filed a voluntary Chapter 7 bankruptcy petition. Before the filing, Riley Components sold goods to Marlow on unsecured credit and had not been paid. After receiving notice of the bankruptcy filing, Riley filed a state-court collection lawsuit and sought to garnish Marlow’s bank account for the unpaid invoice. How should Riley’s postpetition action be characterized?

  • A. A collection action on a prepetition unsecured claim that is generally prohibited by the automatic stay.
  • B. A permitted action because unsecured creditors are bound only after a discharge order is entered.
  • C. A priority claim because Riley attempted to garnish estate funds after the petition date.
  • D. An extinguished claim because all prepetition debts are canceled when the petition is filed.

Best answer: A

Explanation: Riley’s invoice is a prepetition unsecured claim, and the bankruptcy petition triggers an automatic stay against most collection actions. Riley generally must pursue payment through the bankruptcy claims process rather than a separate state-court lawsuit or garnishment. A voluntary bankruptcy petition creates a bankruptcy estate and generally triggers an automatic stay. The stay stops most actions to collect, assess, or recover prepetition claims against the debtor or estate property. An unsecured trade creditor is not allowed to improve its position by suing or garnishing after receiving notice of the bankruptcy filing. Instead, the creditor typically files a proof of claim and shares in distributions according to bankruptcy priority rules. Filing the petition does not immediately discharge all debts, and it does not convert an unsecured creditor into a secured or priority creditor.


Question 4

Topic: Federal Taxation of Individuals

Nolan and Reese are married filing jointly. Their taxable income is $124,000. They have no alternative minimum tax, net investment income tax, additional taxes, or credits other than those listed below.

Tax rate schedule excerpt for married filing jointly: Taxable income over $94,300 but not over $201,050 is taxed as $10,852 plus 22% of the excess over $94,300.

Additional facts:

  • Nonrefundable tax credits: $2,500
  • Refundable tax credits: $1,200
  • Federal income tax withholding: $10,900
  • Estimated tax payments: $2,400

Assuming no penalties or interest, what amount is due with the federal income tax return?

  • A. $2,886 due
  • B. $1,586 due
  • C. $386 due
  • D. $4,086 due

Best answer: C

Explanation: The tax schedule determines the regular income tax before credits. Nonrefundable credits reduce tax, while refundable credits, withholding, and estimated payments reduce the remaining balance due or create an overpayment. Compute the regular income tax first: \(10,852 + 22% × (\)124,000 − \(94,300) =\)10,852 + \(6,534 =\)17,386. The $2,500 nonrefundable credit reduces tax to $14,886. Refundable credits and payments total $1,200 + $10,900 + \(2,400 =\)14,500. Therefore, the amount due with the return is $14,886 − \(14,500 =\)386.


Question 5

Topic: Federal Taxation of Entities (Including Tax Preparation)

Vega, Inc., a calendar-year C corporation, has nexus in State A and other states. Based on the exhibit, what amount should Vega report as State A taxable income?

State A return factAmount or rule
Federal taxable income before State A apportionment and allocation$1,250,000
Included in federal taxable income: net rent from State A real property$60,000
Included in federal taxable income: gain on sale of State B land$140,000
State A sales$4,000,000
Total everywhere sales$10,000,000
State A ruleBusiness income is apportioned using a single-sales factor; nonbusiness real property rent and real property sale gains are allocated to the state where the real property is located. No other State A modifications apply.
  • A. $620,000
  • B. $500,000
  • C. $420,000
  • D. $480,000

Best answer: D

Explanation: State A first removes specifically allocated nonbusiness items from the apportionable base. The remaining business income is apportioned by the State A sales factor, and only the nonbusiness real property rent sourced to State A is then added. Federal taxable income of $1,250,000 includes two nonbusiness items: $60,000 of rent from State A real property and $140,000 of gain from State B land. These are removed from the apportionable business income base, leaving $1,050,000. State A’s single-sales factor is $4,000,000 ÷ $10,000,000, or 40%. Apportioned business income is therefore $420,000. The $60,000 rent is allocated to State A because the real property is located there, while the $140,000 land gain is allocated to State B. State A taxable income is $420,000 + \(60,000 =\)480,000.


Question 6

Topic: Federal Taxation of Property Transactions

Lark LLC, a calendar-year manufacturer, acquired the following assets during 2026 and uses each asset 100% in its active trade or business. Section 179 dollar and taxable income limitations are not binding, and Lark made no election out of any available special depreciation allowance.

AssetFacts
Used CNC machine$140,000; tangible personal property; 7-year MACRS class; acquired from an unrelated dealer; not previously used by Lark
Goodwill and customer list$90,000; acquired in a taxable asset acquisition of an unrelated competitor’s operating business

Lark’s controller proposes to deduct the full $230,000 currently under Section 179. Which interpretation is most appropriate?

  • A. The goodwill and customer list qualify for the special depreciation allowance because they were purchased from an unrelated party and have an ascertainable basis.
  • B. The CNC machine may qualify for Section 179, with any remaining basis then considered for special depreciation allowance and MACRS; the goodwill and customer list must be recovered through amortization.
  • C. The full $230,000 is deductible under Section 179 because all assets were purchased for use in Lark’s active trade or business.
  • D. The used CNC machine is ineligible for any special depreciation allowance because it was not new property when Lark acquired it.

Best answer: B

Explanation: The controlling distinction is the type of property being recovered. The machine is depreciable tangible personal property, so Section 179, special depreciation allowance, and MACRS may be relevant in order; the purchased goodwill and customer list are amortizable Section 197 intangibles. When more than one recovery concept appears plausible, first classify the asset. Section 179 generally applies to qualifying tangible personal property used in an active business and is applied before any special depreciation allowance. The special depreciation allowance, if available, applies after Section 179 to qualified depreciable property, and regular MACRS applies to remaining adjusted basis. Used property is not automatically disqualified if it is acquired in a qualifying purchase and was not previously used by the taxpayer. By contrast, goodwill and customer-based intangibles acquired in the purchase of a business are Section 197 intangibles, recovered through amortization rather than Section 179 expensing, special depreciation, or MACRS depreciation.


Question 7

Topic: Ethics, Professional Responsibilities and Federal Tax Procedures

An IRS examination resulted in a 30-day letter proposing to disallow a deduction and impose an accuracy-related penalty. The taxpayer plans to request Appeals review and argue that, even if the deduction is disallowed, the penalty should not apply because the taxpayer reasonably relied in good faith on a competent tax adviser. Which item would best support that penalty-relief position?

  • A. A prefiling written advice memo from the adviser that identifies the specific deduction, recites the relevant facts provided by the taxpayer, and explains why the return position was supportable.
  • B. A copy of the filed return showing the deduction was reported consistently with the adviser’s software input.
  • C. A post-audit email from the taxpayer stating that the taxpayer believed the deduction was allowable.
  • D. The signed engagement letter showing the adviser was hired to prepare the tax return.

Best answer: A

Explanation: Penalty relief based on reasonable cause and good faith is strongest when the taxpayer can show actual reliance on competent professional advice before filing. The best support is a contemporaneous advice memo tied to the specific position and based on the facts the taxpayer provided. In an audit or Appeals setting, a taxpayer seeking relief from an accuracy-related penalty must do more than show that a professional prepared the return. The taxpayer should be able to demonstrate reasonable cause and good faith, such as competent advice received before filing, full disclosure of relevant facts to the adviser, and actual reliance on that advice. A written prefiling memo analyzing the specific deduction is strong evidence because it documents timing, facts, advice, and reliance. After-the-fact statements or general preparation records are much weaker because they do not show that the taxpayer had a reasonable basis for relying on professional judgment when the return was filed.


Question 8

Topic: Business Law

Stone LLC borrowed $75,000 from Metro Bank to buy business inventory. Stone already owned equipment and inventory. Stone’s authorized manager signed a document titled “Security Agreement” stating: “Stone grants Metro Bank a security interest in all of Stone’s personal property.” Metro advanced the loan proceeds the same day. Stone did not sign or authenticate any other collateral document. Metro then filed a UCC-1 financing statement in the correct filing office using Stone’s exact legal name and identifying the collateral as “inventory and equipment.” Metro did not take possession or control of any collateral. Which is the best interpretation of Metro’s secured position?

  • A. Metro has a perfected security interest because it gave value, Stone owned the collateral, and Metro filed a financing statement identifying inventory and equipment.
  • B. Metro has an attached but unperfected security interest because Stone signed a security agreement and Metro did not take possession of the collateral.
  • C. Metro has a perfected security interest only in the equipment because inventory cannot be perfected by filing unless the secured party has possession or control.
  • D. Metro has neither an attached nor perfected security interest because the authenticated security agreement does not reasonably identify the collateral, and perfection by filing requires attachment.

Best answer: D

Explanation: Metro gave value and Stone had rights in the collateral, but attachment also requires an authenticated security agreement that reasonably identifies the collateral. “All personal property” is too generic for a security agreement, so filing a UCC-1 cannot perfect a security interest that has not attached. A security interest in personal property generally attaches when three requirements are met: the secured party gives value, the debtor has rights in the collateral, and the debtor authenticates a security agreement that reasonably identifies the collateral. A description by UCC collateral type, such as “inventory” or “equipment,” is usually adequate in a security agreement, but a supergeneric phrase such as “all personal property” is not. Perfection normally requires attachment plus an additional step, such as filing a financing statement for goods like inventory and equipment. Metro filed in the correct place with a sufficient financing statement, but the filing does not cure the inadequate collateral description in the security agreement. Because attachment failed, perfection also failed.


Question 9

Topic: Federal Taxation of Individuals

Mia, a cash-method, calendar-year individual taxpayer, received the following items during the year. Based on the exhibit, what amount should Mia include in gross income from these items on her Form 1040?

ItemAmount/description
Form W-2 wages, box 1$96,000
Bank certificate of deposit interest$1,800
Interest on state municipal bonds$1,200
Ordinary dividends from a domestic corporation, of which $2,800 are qualified dividends$4,500
Guaranteed payment from an LLC taxed as a partnership for services$18,000
Employer-paid group accident and health insurance premiums, not included in W-2 wages$7,200
Traditional IRA distribution; Form 1099-R taxable amount is $9,000$12,000 gross distribution
Compensatory damages for personal physical injury$30,000
Punitive damages from the same lawsuit$8,000
  • A. Include $129,300 in gross income.
  • B. Include $137,300 in gross income.
  • C. Include $134,500 in gross income.
  • D. Include $178,700 in gross income.

Best answer: B

Explanation: The includible amount is $137,300. Gross income includes taxable wages, bank interest, all ordinary dividends, guaranteed payments, the taxable portion of retirement-plan distributions, and punitive damages. Qualified dividends are still included in gross income; they may only receive preferential tax rates. Compute the includible items as $96,000 wages + $1,800 bank interest + $4,500 ordinary dividends + $18,000 guaranteed payment + $9,000 taxable IRA distribution + \(8,000 punitive damages =\)137,300. Interest on state municipal bonds is generally excluded from federal gross income. Employer-paid group accident and health insurance premiums are excludable employee fringe benefits when not included in W-2 wages. Compensatory damages received on account of personal physical injury are excluded, but punitive damages are taxable even when related to the same lawsuit.


Question 10

Topic: Federal Taxation of Entities (Including Tax Preparation)

Northstar, Inc., a calendar-year C corporation, has no prior-year carryovers. The controller prepared the following current-year tax workpaper. For this year, charitable contributions are deductible only up to 10% of taxable income computed before the charitable contribution deduction and any NOL deduction; any unused contribution is not deducted currently. Corporate capital losses may offset capital gains only.

Current-year itemAmount
Net sales$900,000
Cost of goods sold(620,000)
Interest income12,000
Deductible operating expenses, excluding separately listed items(310,000)
Federal income tax expense accrued(8,000)
Qualified cash charitable contributions paid(15,000)
Long-term capital gain5,000
Long-term capital loss(28,000)

What conclusion is supported by the exhibit for Northstar’s current-year taxable income or NOL, before considering any carrybacks to other years?

  • A. A current-year net operating loss of $41,000.
  • B. A current-year net operating loss of $18,000.
  • C. A current-year net operating loss of $33,000.
  • D. A current-year net operating loss of $26,000.

Best answer: B

Explanation: Northstar has a current-year NOL of $18,000. The net capital loss beyond capital gains is not currently deductible, federal income tax expense is nondeductible, and the charitable contribution deduction is limited to zero because the pre-contribution taxable income base is negative. Compute taxable income using only currently deductible items. Net sales of $900,000 less cost of goods sold of $620,000, plus $12,000 interest income, less $310,000 deductible operating expenses, equals a $18,000 loss before separately listed items. The $28,000 capital loss is deductible only to the extent of the $5,000 capital gain, so capital transactions have no net current taxable income effect and the remaining capital loss is not part of the NOL. Federal income tax expense is not deductible. Because the charitable contribution limitation base is already negative, none of the $15,000 charitable contribution is deductible currently. Therefore, Northstar reports a current-year NOL of $18,000.


Question 11

Topic: Federal Taxation of Property Transactions

A CPA is reviewing a draft first-year MACRS depreciation schedule for a calendar-year taxpayer. The taxpayer made no Section 179 election, claimed no bonus depreciation, uses the half-year convention, and rounds deductions to the nearest dollar.

AssetSource dataTax classification and rateDraft schedule
CNC machineInvoice $90,000; sales tax $5,400; installation $4,6007-year MACRS; year 1 rate 14.29%Basis $90,000; depreciation $12,861
Computer serverInvoice $30,000; delivery $2,0005-year MACRS; year 1 rate 20.00%Basis $32,000; depreciation $6,400
Office shelvingInvoice $18,0007-year MACRS; year 1 rate 14.29%Not included

What net adjustment to the draft tax depreciation deduction should be proposed?

  • A. Increase depreciation by $1,429
  • B. Decrease depreciation by $2,572
  • C. Increase depreciation by $4,001
  • D. Increase depreciation by $2,572

Best answer: C

Explanation: The draft schedule understated depreciation because it excluded capitalized costs for the CNC machine and omitted the office shelving. Sales tax and installation are included in the depreciable basis, and the omitted shelving must be added using its MACRS rate. Depreciable basis generally includes the asset’s purchase price plus costs necessary to acquire and place the asset in service, such as sales tax, delivery, and installation. The CNC machine’s correct basis is $100,000, so first-year depreciation is $14,290, compared with $12,861 on the draft schedule, an increase of $1,429. The office shelving was omitted, so its first-year depreciation is \(18,000 × 14.29% =\)2,572. The computer server is already correct. The total proposed adjustment is a $4,001 increase.


Question 12

Topic: Ethics, Professional Responsibilities and Federal Tax Procedures

A CPA firm is paid to prepare Apex Corp.’s federal income tax return. The engagement includes the following participants:

  • Dana, a firm partner, has primary responsibility for the overall accuracy of the return and signs it as preparer.
  • Lee, a firm intern, only enters client-provided amounts into tax software and assembles the e-file package.
  • Morgan, an outside consultant paid by the firm, determines Apex’s complex depreciation deductions, which are a substantial portion of the return, but does not sign the return.
  • Riley, Apex’s full-time controller, provides schedules and reviews the draft return as part of regular employment by Apex.

Which participant should be characterized as a nonsigning tax return preparer for federal tax purposes?

  • A. Riley, because Riley reviews the return and provides schedules for the taxpayer.
  • B. Morgan, because Morgan is compensated to prepare a substantial portion of the return without signing it.
  • C. Dana, because Dana signs the return and has overall responsibility for its accuracy.
  • D. Lee, because Lee helps assemble the return package before filing.

Best answer: B

Explanation: Morgan is a nonsigning tax return preparer because Morgan is compensated and prepares a substantial portion of the return. Signing is not required when the person’s compensated work on the return is substantial. For federal tax purposes, a tax return preparer generally includes a person who prepares all or a substantial portion of a return or refund claim for compensation. The signing preparer is the individual with primary responsibility for the overall accuracy of the return and who signs it. A nonsigning preparer can still be treated as a preparer if compensated work on a substantial portion of the return is used. Purely clerical assistance is not enough, and a taxpayer’s regular employee preparing or reviewing the employer’s return is not treated the same as an outside compensated preparer.


Question 13

Topic: Business Law

A CPA is helping a client evaluate whether it can compel a landowner to close on a planned purchase of commercial land. The client and the landowner orally agreed to a $750,000 purchase price, but neither party signed any memorandum identifying the property and price. The client has not paid any purchase price, taken possession, or made improvements to the property. Which business-law conclusion is most appropriate?

  • A. The agreement is voidable by either party because the parties made a mutual mistake about a material fact.
  • B. The agreement is enforceable because the parties orally agreed to the property and purchase price.
  • C. The agreement is void because an oral agreement to sell real property is illegal.
  • D. The agreement is unenforceable against the landowner because a sale of real property generally must be evidenced by a signed writing or an applicable exception.

Best answer: D

Explanation: A contract for the sale of real property is subject to the statute of frauds. Because there is no signed writing and no facts showing an exception such as part performance, the oral agreement is not enforceable against the landowner. The statute of frauds does not make every oral agreement invalid, but it does require certain agreements to be evidenced by a signed writing before they can be enforced in court. Contracts for the sale of real property are a classic category covered by the rule. A writing typically must identify the parties, the property, and the essential terms, and be signed by the party against whom enforcement is sought. Here, no memorandum was signed, and the buyer did not take possession, pay the purchase price, or make improvements that could support a part-performance exception. Therefore, the client generally cannot compel the landowner to close based only on the oral agreement.


Question 14

  • D. $45,000

Best answer: D

Explanation: The taxpayer is above the full phase-in range, so the W-2 wage and UBIA limitation applies. The allowable QBI deduction is the lesser of the QBI component after that limitation and 20% of taxable income reduced by net capital gain. For a non-SSTB when taxable income exceeds the top of the phase-in range, the QBI component for the business is the lesser of 20% of QBI or the greater of two wage/property limits. Here, 20% of QBI is \(56,000. The wage/property limit is the greater of 50% of W-2 wages, or\)45,000, and 25% of W-2 wages plus 2.5% of UBIA, or $22,500 + \(10,000 =\)32,500. Thus, the QBI component is limited to $45,000. The overall taxable income limit is 20% × ($330,000 − \(30,000) =\)60,000, so it does not further reduce the deduction.


Question 15

Topic: Federal Taxation of Entities (Including Tax Preparation)

Triad Corp has nexus in State X and is preparing its State X corporate income tax return. State X apportions business income using a single sales factor and allocates nonbusiness gains from real property to the state where the property is located. For the year, Triad has $1,300,000 of pre-apportionment taxable income, including a $100,000 nonbusiness gain from selling land located in State X; the remaining $1,200,000 is apportionable business income. Triad’s State X sales are $3,000,000, and its everywhere sales are $10,000,000. What amount is included in Triad’s State X taxable income?

  • A. $1,300,000
  • B. $360,000
  • C. $390,000
  • D. $460,000

Best answer: D

Explanation: Business income is apportioned using State X’s single sales factor, while the nonbusiness real property gain is specifically allocated to State X. The sales factor is 30%, so $1,200,000 of business income produces $360,000 of State X income, plus the $100,000 allocated gain. State taxable income for a multistate corporation often separates apportionable business income from specifically allocated nonbusiness income. Here, State X uses a single sales factor: State X sales of $3,000,000 divided by everywhere sales of $10,000,000, or 30%. Only the $1,200,000 of business income is multiplied by that factor, resulting in $360,000 apportioned to State X. The $100,000 gain is nonbusiness income from real property located in State X, so it is allocated entirely to State X rather than apportioned. Total State X taxable income is $360,000 + \(100,000 =\)460,000.


Question 16

Topic: Federal Taxation of Property Transactions

Marin, an individual investor, sold stock at a loss and then bought substantially identical stock:

  • Sold 100 shares on September 15 for $4,500; aggregate adjusted basis was $6,000.
  • Bought 60 substantially identical shares on October 5 for $2,700.
  • No other transactions occurred. Assume $900 of the loss is disallowed under the wash sale rules.

What is Marin’s total tax basis in the 60 replacement shares?

  • A. $3,600
  • B. $2,700
  • C. $4,200
  • D. $1,800

Best answer: A

Explanation: A wash sale disallows the loss on the sale to the extent substantially identical replacement stock is acquired within the wash sale window. The disallowed loss is not lost permanently; it is added to the basis of the replacement shares. When stock is sold at a loss and substantially identical stock is acquired within 30 days before or after the sale date, the wash sale rules can disallow all or part of the realized loss. The disallowed loss is deferred by adding it to the basis of the replacement shares. Here, Marin bought substantially identical stock 20 days after the sale, which is within the wash sale period. The stem provides that $900 of the loss is disallowed. Therefore, the total basis in the 60 replacement shares is their $2,700 purchase cost plus the $900 disallowed loss, or $3,600.


Question 17

Topic: Ethics, Professional Responsibilities and Federal Tax Procedures

After a field audit of Park’s 2024 Schedule C, the revenue agent issued a 30-day letter and examination report proposing to disallow Park’s vehicle expense deduction. Park has already provided the requested mileage log, repair invoices, and client calendar. Park does not plan to submit additional records, but believes the agent drew the wrong conclusion from those records and wants an independent administrative review before going to court. How should Park’s current dispute be characterized?

  • A. A refund claim issue because Park must first pay the proposed deficiency before seeking administrative review.
  • B. An examination issue because all disputes about deductions remain with the revenue agent until tax is assessed.
  • C. A collection issue because the 30-day letter creates an immediately collectible tax liability.
  • D. An appeals issue because Park is contesting the examination’s proposed conclusion after the relevant facts have been developed.

Best answer: D

Explanation: This is an appeals issue. The facts have been developed, the examiner has proposed a conclusion, and Park is disputing that conclusion through independent administrative review. An examination issue generally involves developing the facts, responding to information document requests, substantiating return items, and working with the examiner before a proposed determination is finalized. An appeals issue arises when the IRS has proposed an adjustment and the taxpayer disputes the conclusion based on the developed record, legal interpretation, or hazards of litigation. Here, Park has already provided the requested records and is not trying to submit more evidence. Park is challenging the agent’s proposed disallowance in the 30-day letter, so the matter is properly characterized as an appeals issue.


Question 18

Topic: Business Law

Ridge Supply sold equipment in three separate authorized purchases. No agent signed a personal guaranty, and no contract term alters ordinary agency liability rules. Ridge has not been paid and is preparing pre-suit demand letters.

TransactionFacts known to Ridge when the contract was made
ANora signed ‘Nora Lee, agent for Harbor LLC,’ and Ridge knew Harbor LLC was the principal.
BOmar signed ‘Omar Patel, purchasing agent’ and told Ridge he was buying for a principal, but he did not identify the principal. Ridge later learned the principal was Pine Inc.
CMia signed in her own name and did not tell Ridge she was acting for anyone else. Ridge later learned she was acting for Quinn LLC.

What should Ridge do next to identify the parties bound on these contracts?

  • A. Send demands to Harbor LLC for Transaction A; to Omar and Pine Inc. for Transaction B; and to Mia and Quinn LLC for Transaction C.
  • B. Send demands only to Harbor LLC, Pine Inc., and Quinn LLC, because actual authority makes only the principals bound.
  • C. Send demands only to Nora, Omar, and Mia, because each contract was signed by an agent.
  • D. Send demand to Harbor LLC now, but wait for Pine Inc. and Quinn LLC to ratify before seeking payment on Transactions B and C.

Best answer: A

Explanation: Harbor LLC was a disclosed principal, so Nora is generally not personally bound absent a guaranty or contrary agreement. Pine Inc. was partially disclosed and Quinn LLC was undisclosed, so both the agent and the authorized principal are bound in those transactions. Agency contract liability depends on what the third party knew when the contract was made. If the principal is disclosed, the third party knows both that the agent is acting for a principal and the principal’s identity; the principal is bound and the agent generally is not. If the principal is partially disclosed, the third party knows an agency exists but not the principal’s identity; both the agent and principal are bound. If the principal is undisclosed, the third party believes the agent is acting personally; both the agent and principal are bound when the agent had authority and no contract term changes that result. Ridge should therefore proceed against Harbor LLC only for Transaction A, and against both the agents and principals for Transactions B and C.


Question 19

Topic: Federal Taxation of Individuals

A CPA is reviewing a taxpayer’s draft Form 1040 for income completeness. The source documents show the following receipts for the year:

ReceiptAmount
W-2 wages$78,000
Form 1099-G unemployment compensation$3,600
Interest on municipal bonds$900
Cash gift from the taxpayer’s aunt$10,000

The draft Form 1040 reports $78,000 of wages, $0 of unemployment compensation, and $0 of tax-exempt interest. Which conclusion is correct?

  • A. Gross income is incomplete by $4,500 because unemployment compensation and municipal bond interest are both taxable.
  • B. Gross income is incomplete by $13,600 because unemployment compensation and the cash gift are both taxable.
  • C. Gross income is incomplete by $3,600; unemployment compensation is taxable, municipal bond interest should be reported as tax-exempt interest, and the gift is excluded.
  • D. Gross income is complete because only the W-2 wages are taxable.

Best answer: C

Explanation: The draft return omits taxable unemployment compensation, so gross income is understated by $3,600. Municipal bond interest is excluded from federal gross income but should still be shown as tax-exempt interest on Form 1040, and the cash gift is excluded from the recipient’s income. A completeness review compares source documents to the income amounts reported on the return and distinguishes taxable receipts from excluded receipts. Wages and unemployment compensation are taxable gross income. Interest on municipal bonds is generally excluded from federal gross income, but it is reported separately on Form 1040 as tax-exempt interest. A gift received from an individual is excluded from the recipient’s gross income. Therefore, the only omitted taxable receipt is the $3,600 unemployment compensation, although the draft should also be updated to report the $900 municipal bond interest as tax-exempt interest.


Question 20

Topic: Federal Taxation of Entities (Including Tax Preparation)

Maple Ridge, Inc. has used a valid calendar-year S corporation election for several years. On May 15 of the current year, 20% of its stock was transferred to Brook Fund, LP, a domestic limited partnership. Before the transfer, all shareholders were U.S. individuals, and the corporation did not request relief for an inadvertent termination. The preparer concluded that the S election terminated on May 15, so the year must be reported as an S termination year: S short-year items pass through to shareholders, while items allocated to the C corporation short year are taxed at the entity level.

Which authority excerpt best supports the preparer’s conclusion?

  • A. An S election terminates on the date the corporation first has an ineligible shareholder; a partnership shareholder is ineligible, and items allocated to the resulting C corporation short year are taxed to the corporation.
  • B. A corporation with voting and nonvoting common stock remains eligible if the shares have identical distribution and liquidation rights.
  • C. An S corporation with accumulated C corporation earnings and profits and excess passive investment income for three consecutive years loses S status at the beginning of the next tax year.
  • D. A voluntary S election revocation is effective only if shareholders owning more than 50% of the shares consent to the revocation.

Best answer: A

Explanation: Brook Fund, LP is an ineligible S corporation shareholder, so Maple Ridge’s S election terminates when the partnership becomes a shareholder. A midyear eligibility termination creates an S termination year, with C corporation short-year items taxed at the entity level rather than passed through. An S corporation must continuously meet eligibility requirements. Eligible shareholders generally include U.S. individuals, certain estates or trusts, and certain exempt organizations; partnerships are not eligible shareholders. When stock is transferred to an ineligible shareholder, the S election terminates on the transfer date unless relief for an inadvertent termination is obtained. The tax year containing the termination is divided into an S short year and a C corporation short year. Items allocated to the S short year retain pass-through treatment, while items allocated to the C corporation short year are reported by and taxed to the corporation.


Question 21

Topic: Federal Taxation of Property Transactions

A calendar-year taxpayer purchased machinery for $96,000 and placed it in service on November 18, Year 1. The machinery is 5-year MACRS property depreciated using the 200% declining-balance method, and the mid-quarter convention applies. No Sec. 179 deduction or bonus depreciation is claimed.

Use this MACRS rate table for 5-year property under the mid-quarter convention:

Tax yearQ1 placed in serviceQ2 placed in serviceQ3 placed in serviceQ4 placed in service
Year 135.00%25.00%15.00%5.00%
Year 226.00%30.00%34.00%38.00%

What is the MACRS depreciation deduction for Year 2?

  • A. $4,800
  • B. $30,720
  • C. $36,480
  • D. $32,640

Best answer: C

Explanation: Because the machinery was placed in service on November 18, it falls in the fourth quarter under the mid-quarter convention. The Year 2 rate for Q4 placed-in-service 5-year property is 38.00%, so the deduction is $96,000 multiplied by 38.00%. MACRS depreciation uses the applicable recovery period, convention, and placed-in-service date to select the correct table rate. Here, the property is 5-year MACRS property and the mid-quarter convention applies. Since the machinery was placed in service on November 18, it is treated as placed in service in the fourth quarter. For the second tax year, the table gives a 38.00% rate for property placed in service in Q4. Therefore, Year 2 depreciation is $96,000 × 38.00%, or $36,480. Sec. 179 and bonus depreciation are ignored because the facts state they are not claimed.


Question 22

Topic: Ethics, Professional Responsibilities and Federal Tax Procedures

Riley, a CPA authorized to practice before the IRS, is reviewing proposed engagement terms. Assume each fee is reasonable in amount and state law imposes no additional restriction. Under IRS practice standards, a fee based on a percentage of the tax refund obtained or taxes saved is a contingent fee. Which engagement term is acceptable without creating a contingent-fee issue?

  • A. Prepare a 2025 original Form 1040 for 15% of the federal income tax refund shown on the return.
  • B. Represent a taxpayer in an IRS examination of a 2023 Form 1040 for 25% of any reduction in the proposed deficiency.
  • C. Prepare a corporate income tax refund claim for 30% of the refund because the client has signed written consent to the fee.
  • D. Prepare a 2023 Form 1040-X claiming a missed credit for 20% of any refund when the IRS has not contacted the taxpayer about 2023.

Best answer: B

Explanation: IRS practice standards generally prohibit contingent fees for preparing original returns and ordinary refund claims. An exception applies to services connected with an IRS examination or challenge, so the exam-representation arrangement is acceptable under the stated facts. A contingent fee includes a fee based on a percentage of a refund or tax savings. Under IRS practice standards, practitioners generally may not charge contingent fees for preparing original tax returns or for routine amended returns or refund claims. However, a contingent fee is allowed for services connected with an IRS examination or challenge to a return, such as representing a taxpayer after the IRS has proposed a deficiency. Written client consent does not convert an otherwise prohibited contingent fee into an acceptable one.


Question 23

Topic: Business Law

Crestline Corp. asks whether it is bound by an equipment lease signed by its purchasing clerk. The documented facts are:

FactDetail
Authority at signingThe clerk had neither actual nor apparent authority to sign equipment leases for Crestline.
Unauthorized contractThe clerk signed a $48,000 equipment lease with Delta Systems in Crestline’s name.
Management responseAfter an officer with authority to approve leases learned all material terms and the clerk’s lack of authority, Crestline kept the equipment, used it for two months, and made the first lease payment.
Third-party actionDelta did not withdraw from the transaction before Crestline used the equipment or made the payment.

Which conclusion is best supported by these facts?

  • A. Crestline may keep the equipment benefits already received but reject the remaining lease obligations.
  • B. Crestline is not bound because the clerk lacked actual and apparent authority when the lease was signed.
  • C. Crestline is bound because it impliedly ratified the lease by knowingly accepting its benefits.
  • D. Crestline is bound only if it sent Delta a written ratification before making the first payment.

Best answer: C

Explanation: Crestline likely ratified the unauthorized lease. Once an authorized officer knew the material facts and Crestline kept, used, and paid for the equipment, Crestline impliedly accepted the transaction’s benefits and became bound. Ratification occurs when a principal later affirms an agent’s unauthorized act. The affirmation can be express or implied, including by knowingly accepting benefits from the transaction. The principal must have knowledge of the material facts, and the third party must not have withdrawn before ratification. Here, the clerk lacked authority at signing, but an authorized officer later learned the key facts and Crestline kept and used the equipment and made a payment. That conduct supports implied ratification of the entire lease, not merely the favorable parts.


Question 24

Topic: Federal Taxation of Individuals

A CPA is advising Lynn, a single taxpayer, about avoiding the federal individual estimated tax underpayment penalty. Lynn’s prior-year adjusted gross income was $180,000, and her prior-year total tax was $28,000 on a 12-month return that showed a tax liability. Lynn’s current-year total tax is expected to be $38,000, and she will have no withholding. If Lynn pays timely equal estimated tax installments, what is the smallest total current-year estimated tax payment amount that satisfies a safe harbor?

  • A. $28,000
  • B. $30,800
  • C. $34,200
  • D. $38,000

Best answer: B

Explanation: Lynn can satisfy the estimated tax safe harbor by paying the lesser of 90% of current-year tax or 110% of prior-year tax because her prior-year AGI exceeded the high-income threshold. The smaller amount is 110% of $28,000, or $30,800. For an individual, timely estimated tax payments generally avoid the underpayment penalty if they equal at least the required annual payment. That amount is generally the lesser of 90% of the current-year tax or 100% of the prior-year tax. However, for a higher-income taxpayer, the prior-year tax safe harbor increases to 110% of prior-year tax. Lynn’s prior-year AGI was $180,000, so the 110% rule applies. Her prior-year safe harbor is \(28,000 × 110% =\)30,800. Her current-year safe harbor is \(38,000 × 90% =\)34,200. The smaller safe harbor amount is $30,800.
