,Q1. A cash-basis taxpayer receives a check for services rendered on December 31,
2025, but does not deposit it until January 4, 2026. The client's account had sufficient
funds. In which year must the taxpayer report the income?
A. 2025, because the check was received and the taxpayer had constructive receipt.
B. 2025, because the check was received and the taxpayer had actual receipt.
C. 2026, because the taxpayer did not deposit the check until 2026.
D. 2026, because the taxpayer did not have constructive receipt until the check was
deposited.
Correct Answer: A. 2025, because the check was received and the taxpayer had
constructive receipt.
Rationale: Under the constructive receipt doctrine, income is recognized when it is
credited to the taxpayer's account or made available without substantial restrictions. A
check received before year-end is constructively received even if not deposited, provided
the payer had sufficient funds. Actual receipt is not required. Therefore, the income is
taxable in 2025.
Why Wrong:
B - Actual receipt is not the standard; constructive receipt suffices, but this option is
correct for the wrong reason.
C - Deposit date is irrelevant if the check is received and available; constructive
receipt applies.
D - Constructive receipt occurs upon receipt, not deposit.
Reference: IRC § 451; Treas. Reg. § 1.451-2; Internal Revenue Service, Taxable Income,
Publication 538.
Q2. In a like-kind exchange under IRC § 1031, a taxpayer gives up real property with
an adjusted basis of $100,000 and fair market value of $200,000, and receives real
property worth $150,000 plus $50,000 cash. What is the recognized gain?
A. $0
B. $50,000
C. $100,000
D. $150,000
Correct Answer: B. $50,000
Rationale: In a like-kind exchange, realized gain is $100,000 ($200,000 FMV received
minus $100,000 basis). However, gain is recognized only to the extent of boot received
(cash), which is $50,000. The remaining $50,000 is deferred. Thus, recognized gain is
$50,000.
Why Wrong:
A - Boot received triggers recognition; gain is not zero when boot is present.
C - This is the total realized gain, not the recognized gain; only boot is recognized.
Page 3
, D - This exceeds the realized gain and is incorrect.
Reference: IRC § 1031; Treas. Reg. § 1.1031(b)-1; Internal Revenue Service, Like-Kind
Exchanges, Publication 544.
Q3. Which of the following items is NOT deductible as an itemized deduction on
Schedule A for an individual taxpayer in 2025?
A. State and local income taxes paid, up to the $10,000 cap.
B. Mortgage interest on acquisition indebtedness up to $750,000.
C. Medical expenses exceeding 7.5% of adjusted gross income.
D. Premiums paid for life insurance policies.
Correct Answer: D. Premiums paid for life insurance policies.
Rationale: Life insurance premiums are personal expenses and are not deductible. State
and local taxes, qualified mortgage interest, and medical expenses exceeding the threshold
are deductible as itemized deductions, subject to limitations.
Why Wrong:
A - State and local taxes are deductible subject to the $10,000 cap.
B - Mortgage interest is deductible within limits.
C - Medical expenses are deductible if they exceed 7.5% of AGI.
Reference: IRC §§ 163, 164, 213; Internal Revenue Service, Schedule A Instructions.
Q4. A corporation has current earnings and profits (E&P) of $50,000 and
accumulated E&P of $100,000. It distributes $120,000 to its sole shareholder. What is
the tax treatment of the distribution?
A. $120,000 is a taxable dividend.
B. $120,000 is a return of capital, reducing the shareholder's basis.
C. $150,000 is a taxable dividend, and the excess is a return of capital.
D. $120,000 is a dividend to the extent of current E&P, and the rest is a return of
capital.
Correct Answer: A. $120,000 is a taxable dividend.
Rationale: A distribution is a dividend to the extent of current and accumulated E&P.
Here, total E&P is $150,000 ($50,000 + $100,000), so the $120,000 distribution is fully
covered and is a taxable dividend. There is no return of capital because the distribution
does not exceed E&P.
Why Wrong:
B - Return of capital only occurs when distributions exceed E&P.
C - The total E&P is $150,000, but the distribution is only $120,000, so no excess.
D - Distributions are first from current E&P, then accumulated, but here total E&P
covers the full amount.

check received before year-end is constructively received even if not deposited, provided

Q2. In a like-kind exchange under IRC § 1031, a taxpayer gives up real property with
an adjusted basis of $100,000 and fair market value of $200,000, and receives real
property worth $150,000 plus $50,000 cash. What is the recognized gain?
A. $0
B. $50,000
C. $100,000
D. $150,000
Correct Answer: B. $50,000
Rationale: In a like-kind exchange, realized gain is $100,000 ($200,000 FMV received
minus $100,000 basis). However, gain is recognized only to the extent of boot received
(cash), which is $50,000. The remaining $50,000 is deferred. Thus, recognized gain is
$50,000.
Why Wrong:

, D - This exceeds the realized gain and is incorrect.

Exchanges, Publication 544.
Q3. Which of the following items is NOT deductible as an itemized deduction on
Schedule A for an individual taxpayer in 2025?
A. State and local income taxes paid, up to the $10,000 cap.
B. Mortgage interest on acquisition indebtedness up to $750,000.
C. Medical expenses exceeding 7.5% of adjusted gross income.
D. Premiums paid for life insurance policies.
Correct Answer: D. Premiums paid for life insurance policies.
Rationale: Life insurance premiums are personal expenses and are not deductible. State
and local taxes, qualified mortgage interest, and medical expenses exceeding the threshold
are deductible as itemized deductions, subject to limitations.
Why Wrong:
A - State and local taxes are deductible subject to the $10,000 cap.
B - Mortgage interest is deductible within limits.

Q4. A corporation has current earnings and profits (E&P) of $50,000 and
accumulated E&P of $100,000. It distributes $120,000 to its sole shareholder. What is
the tax treatment of the distribution?
A. $120,000 is a taxable dividend.
B. $120,000 is a return of capital, reducing the shareholder's basis.
C. $150,000 is a taxable dividend, and the excess is a return of capital.
D. $120,000 is a dividend to the extent of current E&P, and the rest is a return of
capital.
Correct Answer: A. $120,000 is a taxable dividend.
Rationale: A distribution is a dividend to the extent of current and accumulated E&P.
Here, total E&P is $150,000 ($50,000 + $100,000), so the $120,000 distribution is fully
covered and is a taxable dividend. There is no return of capital because the distribution
does not exceed E&P.
Why Wrong:
B - Return of capital only occurs when distributions exceed E&P.
C - The total E&P is $150,000, but the distribution is only $120,000, so no excess.
D - Distributions are first from current E&P, then accumulated, but here total E&P
covers the full amount.
