Apply Adjustments To Gross Income - CPA Reg

  1. A single 32-year-old taxpayer with wages of $45,000 is not an active participant in any employer-sponsored retirement plan. He contributes $6,500 to a traditional IRA. What is his IRA deduction?
    Answer: $6,500 (full amount; non-active participants may deduct the full IRA contribution regardless of income level) A taxpayer who is not an active participant in an employer-sponsored retirement plan (and whose spouse is also not an active participant) may deduct the full IRA contribution regardless of income level. The income phase-outs for IRA deductibility apply only to active participants in employer-sponsored plans. Since this taxpayer has no employer plan coverage, his $6,500 contribution is fully deductible. Options A and C invent restrictions that do not apply to non-participants. Option B applies a 50% limitation that does not exist.
  2. The above-the-line deduction for self-employment tax equals which of the following?
    Answer: 50% of the total self-employment tax computed for the year IRC Section 164(f) allows self-employed individuals to deduct one-half (50%) of their self-employment tax as an above-the-line deduction. This mirrors the treatment of employees, who are effectively not taxed on the employer's share of FICA taxes (the employer deducts it as a business expense). Option B is incorrect; only half is deductible. Option C describes the FICA tax rate applied to net wages but does not correctly describe the SE tax deduction formula. Option D is the net earnings from self-employment base used to compute SE tax, not the deductible amount.
  3. A self-employed individual contributes $22,000 to a SEP-IRA. Her net self-employment compensation (after the SE tax deduction) is $110,000. The SEP contribution limit is 25% of net SE compensation (or the annual dollar limit of $69,000 in 2024). Is the full $22,000 deductible?
    Answer: Yes; for self-employed individuals the effective SEP deductible limit is approximately 20% of net SE compensation after the SE tax deduction - not 25% - because the 25% plan rate is applied to earned income reduced by the contribution itself. 20% x $110,000 = $22,000, which equals the contribution, so the full $22,000 is deductible For self-employed individuals, the SEP deduction limit is not simply 25% of net SE compensation. The 25% plan rate applies to earned income reduced by the SEP contribution itself - a circular calculation that simplifies to an effective rate of approximately 20% of net SE compensation after the SE tax deduction. Here: 20% x $110,000 = $22,000. Since the contribution of $22,000 equals the maximum deductible amount and does not exceed the $69,000 annual dollar limit, the full $22,000 is deductible as an above-the-line adjustment. Answer B is correct. Option A is incorrect; SEP contributions are deductible above-the-line for self-employed individuals. Options C and D misstate the applicable rules.
  4. A single taxpayer has wages of $200,000 and contributes $22,500 to her employer's 401(k) plan, making her an active participant. She also has $30,000 of net SE income. She wants to make a deductible traditional IRA contribution. The 2024 single active-participant phase-out ceiling is $87,000. Which analysis is most accurate?
    Answer: No IRA deduction is available; her MAGI far exceeds the $87,000 upper phase-out limit for single active participants, completely eliminating the traditional IRA deductibility Her MAGI includes both wages and SE income. Even wages alone ($200,000) exceed the $87,000 upper phase-out limit for single active participants by more than $100,000. All income types are included in MAGI for this purpose; SE income does not receive a carve-out. The 401(k) contribution reduces taxable income but does not reduce MAGI for IRA phase-out purposes (MAGI adjustments for IRA purposes add back the 401(k) deduction). Options A and B invoke exceptions that do not exist. Option C fabricates a partial deduction above the phase-out ceiling.
  5. A taxpayer pays $30,000 per year in alimony under a 2016 divorce decree. A 2023 modification increases payments to $36,000. Which analysis of the deductibility of the $36,000 payment is most accurate?
    Answer: Whether the full $36,000 is deductible depends on whether the 2023 modification expressly states that the post-2018 rules apply; absent such language, the pre-2019 rules generally continue to apply and the payments remain deductible Under TCJA transition rules, a modification of a pre-2019 divorce agreement does not automatically lose the grandfathered pre-2019 treatment. The old rules continue to apply unless the modification agreement expressly provides that the post-2018 rules shall apply. If the 2023 modification is silent on which tax treatment governs, the pre-2019 treatment is generally preserved, and the full $36,000 remains deductible by the payer and includable by the recipient. Option A and B assume the pre-2019 treatment automatically continues regardless of the modification's language. Option C assumes modification always triggers post-TCJA treatment, which is incorrect.
  6. A single taxpayer is not an active participant in any employer plan, but her spouse IS an active participant in his employer's 401(k). Her MAGI is $228,000. The 2024 phase-out range for a non-active participant married to an active participant is $230,000 to $240,000. She contributes $7,000 to a traditional IRA. What is her allowable IRA deduction?
    Answer: $7,000 (full deduction; MAGI is below the $230,000 lower limit of the applicable phase-out range) When the taxpayer is not an active participant but her spouse is, a separate (higher) phase-out range applies - $230,000 to $240,000 for 2024. Because her MAGI of $228,000 falls below the $230,000 lower limit, she has not yet entered the phase-out range, and the full $7,000 is deductible. Option A is incorrect; spousal active participation triggers a phase-out only when income is in or above the applicable range. Option B applies a flat 50% limitation that does not exist. Option C invents a 10% base deduction.
  7. A single elementary school teacher spent $480 on classroom supplies, books, and decorations for his students during the year. What is his educator expense deduction?
    Answer: $300 (statutory maximum for a single eligible educator) Eligible educators may deduct up to $300 per year of qualified educator expenses as an above-the-line deduction under IRC Section 62(a)(2)(D). Since the teacher spent $480, the deduction is capped at $300. The deduction does not require itemizing - it reduces AGI directly. Option B uses the actual amount without applying the $300 cap. Option C incorrectly applies a 50% limitation. Option D incorrectly requires itemization.
  8. A taxpayer has wages of $120,000 and paid $2,500 in student loan interest. MAGI before the student loan interest deduction is $120,000. The 2024 single-filer phase-out ends at $95,000. Which analysis is most accurate?
    Answer: No deduction is allowed; MAGI of $120,000 exceeds the upper phase-out limit of $95,000, completely eliminating the student loan interest deduction When MAGI exceeds the upper limit of the phase-out range ($95,000 for single filers in 2024), the student loan interest deduction is completely phased out and no deduction is allowed. The taxpayer's MAGI of $120,000 is $25,000 above the upper limit, placing him entirely outside the eligible range. The fact that he paid the full $2,500 maximum is irrelevant when the income threshold eliminates the deduction. Options A, C, and D all allow a deduction when none is available at this income level.
  9. A taxpayer has wages of $80,000 and net SE income of $20,000. SE tax is $2,827 (50% deductible = $1,413). Self-employed health insurance premiums paid are $6,000. Traditional IRA contribution is $6,000 (fully deductible; not an active participant). What is AGI?
    Answer: $86,587 Total income = $80,000 + $20,000 = $100,000. Above-the-line deductions: SE tax deduction $1,413 + self-employed health insurance $6,000 + IRA $6,000 = $13,413. AGI = $100,000 - $13,413 = $86,587. Option A omits all deductions. Option C omits the SE tax deduction. Option D omits SE income and the deductions.
  10. A single 40-year-old taxpayer enrolled in a qualifying high-deductible health plan (HDHP) contributes $3,800 to her Health Savings Account (HSA) during 2024. The self-only HDHP contribution limit for 2024 is $4,150. What is the HSA deduction?
    Answer: $3,800 (fully deductible; HSA contributions are not subject to AGI phase-outs) HSA contributions made directly by the taxpayer are deductible above the line under IRC Section 223(a). They are not subject to any AGI phase-out and do not require itemizing. The full $3,800 contribution is deductible because it does not exceed the 2024 self-only contribution limit of $4,150. Option B applies a 50% limitation that does not exist. Option C is incorrect; HSA deductions are above-the-line. Option D misapplies the catch-up contribution rule (age 55+ may contribute an additional $1,000) as a general age restriction.
  11. A self-employed consultant has net profit of $45,000 from Schedule C. She pays $52,000 in health insurance premiums for herself and family. She has no other self-employment activity. Which analysis of her self-employed health insurance deduction is most accurate?
    Answer: The deduction is limited to the taxpayer's earned income from the self-employment activity, which equals net SE profit reduced by the SE tax deduction (and any qualified plan contributions) - not simply the Schedule C net profit; here the earned income cap is approximately $41,800 after the SE tax deduction on $45,000 of net profit, which is less than both the $52,000 premium paid and the $45,000 net profit figure Under IRC Section 162(l), the self-employed health insurance deduction is limited to the taxpayer's earned income from the trade or business for which the plan was established. For self-employed individuals, earned income for this purpose equals net SE profit reduced by the SE tax deduction and any qualified retirement plan contribution deductions - not simply the Schedule C net profit. Here, with $45,000 of net SE profit, the SE tax deduction is approximately $3,180, leaving earned income of approximately $41,820. The $52,000 in premiums exceeds this cap, so the deduction is limited to the earned income amount - not the full $45,000 net profit. Answer A is correct. Option B ignores the earned income limitation entirely. Option C applies a 50% limitation that no longer exists. Option D incorrectly treats excess premiums as triggering complete disallowance.
  12. A self-employed consultant has net SE income of $100,000. SE tax is approximately $14,130, giving an SE tax deduction of $7,065. Net SE compensation after the SE tax deduction is $92,935. She contributes $30,000 to a SEP-IRA. The SEP limit is 25% of net SE compensation. Which analysis of the SEP deduction is most accurate?
    Answer: Only $18,587 is deductible; for self-employed individuals the SEP limit equals approximately 20% of net SE compensation after the SE tax deduction (the 25% plan rate applied to earned income reduced by the contribution itself), and 20% x $92,935 = $18,587; the $30,000 contribution exceeds this limit For self-employed individuals, the SEP deduction limit equals the plan rate applied to earned income reduced by the contribution itself - a circular calculation that simplifies to approximately 20% of net SE compensation after the SE tax deduction. Here: 20% x $92,935 = $18,587. Since the $30,000 contribution exceeds the $18,587 limit, only $18,587 is deductible. Answer D is correct. Option A ignores the compensation-based limitation. Option B applies 25% to gross SE income before the SE tax deduction, overstating the base. Option C correctly notes that $30,000 is below the $69,000 dollar limit but ignores the lower compensation-based limit that controls here.
  13. A taxpayer's bank charged a $425 penalty for early withdrawal from a certificate of deposit. His wages were $65,000. What is AGI after accounting for this penalty?
    Answer: $64,575 (the full $425 penalty is deductible as an above-the-line adjustment) Under IRC Section 62(a)(9), penalties paid on the early withdrawal of funds from time savings accounts are deductible as an above-the-line adjustment. The full $425 is deductible. AGI = $65,000 - $425 = $64,575. Option A incorrectly denies the deduction. Option B applies a 50% limitation that does not exist. Option D has no basis in the tax code.
  14. A single taxpayer paid $3,800 in qualifying student loan interest. His MAGI before this deduction is $82,000. The 2024 phase-out range for single filers is $80,000 to $95,000. What is the allowable student loan interest deduction?
    Answer: $2,167 (phase-out reduces the $2,500 cap by the applicable ratio) The student loan interest deduction is capped at $2,500. The phase-out reduces this cap based on MAGI in the phase-out range. Excess MAGI = $82,000 - $80,000 = $2,000. Phase-out ratio = $2,000 / $15,000 = 13.33%. Reduction = $2,500 x 13.33% = $333. Allowable deduction = $2,500 - $333 = $2,167. Option A uses the actual interest paid, which exceeds the $2,500 cap. Option B applies the full cap without the phase-out reduction. Option C uses an incorrect ratio.
  15. A self-employed attorney pays $14,400 in health insurance premiums for herself, her spouse, and dependent children. Her net profit from self-employment before this deduction is $85,000. What is the self-employed health insurance deduction?
    Answer: $14,400 (100% of premiums paid) Self-employed individuals may deduct 100% of health insurance premiums paid for themselves, their spouse, and dependents as an above-the-line deduction under IRC Section 162(l). The deduction is limited to net profit from the self-employment activity for which the plan was established. Here, $14,400 is less than the $85,000 net profit, so the full $14,400 is deductible. Option A applies a 50% limit that does not exist. Option B applies a 75% limit. Option D uses an incorrect percentage-based limitation.
  16. A single taxpayer has MAGI of $86,000 before the student loan interest deduction. She paid $2,500 in qualifying student loan interest. The 2024 phase-out range is $80,000 to $95,000. What is the correct deduction amount?
    Answer: $1,500; the phase-out reduces the $2,500 cap by 40% based on MAGI exceeding the threshold by $6,000 of the $15,000 range Phase-out calculation: Excess MAGI = $86,000 - $80,000 = $6,000. Phase-out range = $95,000 - $80,000 = $15,000. Phase-out percentage = $6,000 / $15,000 = 40%. Reduction = $2,500 x 40% = $1,000. Allowable = $2,500 - $1,000 = $1,500. Option A applies the cap without the phase-out reduction. Option B eliminates the deduction entirely when MAGI is within the phase-out range (not beyond it). Option D applies an incorrect calculation method.
  17. Above-the-line deductions (adjustments to gross income) differ from itemized deductions in which of the following ways?
    Answer: Above-the-line deductions reduce AGI and are available regardless of whether the taxpayer itemizes or claims the standard deduction Above-the-line deductions (adjustments to gross income listed on Schedule 1 of Form 1040) reduce AGI whether or not the taxpayer itemizes. This makes them particularly valuable because they lower AGI, which serves as the base for many other limitations and phase-outs. Itemized deductions, by contrast, only benefit taxpayers whose total itemized deductions exceed the standard deduction. Option B describes a pre-TCJA miscellaneous itemized deduction rule, not above-the-line deductions. Option C is incorrect; many above-the-line deductions (educator expenses, IRA contributions, student loan interest) are available to employees and non-self-employed taxpayers. Option D describes the limitation on itemized deductions.
  18. A single active-participant taxpayer has MAGI of $83,000 and contributes $7,000 to a traditional IRA. The 2024 phase-out range for single active participants is $77,000 to $87,000. What is the allowable IRA deduction?
    Answer: $2,800 (phase-out reduces the $7,000 contribution proportionally based on MAGI in the phase-out range) Phase-out calculation: Excess MAGI = $83,000 - $77,000 = $6,000. Phase-out range = $87,000 - $77,000 = $10,000. Phase-out ratio = $6,000 / $10,000 = 60%. Reduction = $7,000 x 60% = $4,200. Allowable deduction = $7,000 - $4,200 = $2,800. Option A incorrectly treats $83,000 as above the phase-out ceiling ($87,000). Option B applies a flat 50% without calculating the actual phase-out. Option D ignores the phase-out that clearly applies.
  19. A 55-year-old single taxpayer contributes $7,000 plus a $1,000 catch-up contribution for a total of $8,000 to a traditional IRA. She is not an active participant in any employer-sponsored plan. Which analysis is most accurate?
    Answer: The full $8,000 is deductible; taxpayers age 50 or older may make catch-up IRA contributions, and non-active participants may deduct the full contribution regardless of income Taxpayers age 50 or older may contribute an additional $1,000 in catch-up contributions to a traditional IRA, for a total 2024 limit of $8,000. Since she is not an active participant in any employer plan, there is no income-based phase-out on the IRA deduction, and the full $8,000 contribution is deductible as an above-the-line adjustment. Option A incorrectly denies the deductibility of catch-up contributions. Option C has no basis in law; catch-up contributions may go to a traditional IRA. Option D invents a pre-retirement proximity limitation.
  20. A taxpayer paid $12,000 in alimony during the current year under a divorce decree signed in 2015. AGI before this deduction is $95,000. What is AGI after the alimony deduction?
    Answer: $83,000 (full $12,000 is deductible for pre-2019 agreements) The divorce decree was signed in 2015, making it a pre-2019 agreement that retains the old alimony rules. The full $12,000 is deductible as an above-the-line deduction. AGI = $95,000 - $12,000 = $83,000. Option A incorrectly applies the post-2018 rules to a pre-2019 agreement. Option B applies a 50% limit that does not exist. Option D applies a 10% floor that does not apply to alimony deductions.
