CPA Exam Estate and Gift Tax
Last updated: May 2, 2026
Estate and Gift Tax questions are one of the highest-leverage areas to study for the CPA Exam. This guide breaks down the rule, the elements you need to recognize, the named traps that catch most students, and a memory aid that scales to test day. Read it once, then practice the same sub-topic adaptively in the app.
The rule
The federal transfer tax system under IRC §§2001–2801 imposes a unified gift and estate tax on lifetime and testamentary transfers, with a single cumulative basic exclusion amount (BEA) shared across both. Under IRC §2503(b), each donor may exclude the first $19,000 (2025 indexed amount) per donee per year before any taxable gift arises; gifts above that reduce the donor's lifetime BEA before any tax is owed. Under IRC §2010(c)(5), a surviving spouse may elect portability of the deceased spouse's unused exclusion (DSUE) by filing a timely Form 706. The marital deduction (IRC §2523 for gifts; §2056 for estates) and the charitable deduction allow unlimited transfers to a U.S.-citizen spouse or qualifying charity without using exclusion.
Elements breakdown
Annual Exclusion (IRC §2503(b))
A per-donee, per-year exclusion that applies before lifetime exclusion is consumed; gifts of present interests only.
- Must be a present interest, not a future interest
- Applied per donee, per calendar year
- Indexed annually for inflation
- Spouses may gift-split under §2513 to double the exclusion
- Crummey withdrawal power converts trust gift to present interest
Lifetime Basic Exclusion Amount (IRC §2010(c))
Cumulative dollar amount sheltered from gift and estate tax across the donor's lifetime and at death.
- Unified across gift and estate transfers
- Reduced by taxable gifts made during life
- Remaining amount shelters the gross estate at death
- Sunset to roughly half on January 1, 2026 absent legislation
- Tracked on Form 709 (gift) and Form 706 (estate)
Marital and Charitable Deductions
Unlimited deductions that bypass both the annual exclusion and the BEA when transferring to a qualifying recipient.
- Donee or heir must be U.S.-citizen spouse for unlimited marital
- Non-citizen spouse limited to $190,000 (2025) per §2523(i)
- Charitable deduction requires qualified §170(c) organization
- Terminable interests generally disqualify marital deduction
- QTIP election under §2056(b)(7) preserves marital deduction
Portability and DSUE (IRC §2010(c)(5))
Election allowing a surviving spouse to add the deceased spouse's unused exclusion to her own.
- Election made on a timely filed Form 706
- Applies only to the most recently deceased spouse
- Does not apply to the GST exemption
- Requires affirmative election even if no estate tax is owed
- Rev. Proc. 2022-32 allows late election within five years
Tuition and Medical Exclusions (IRC §2503(e))
Direct payments of tuition or medical expenses on behalf of any individual that are not gifts at all.
- Payment must be made directly to the institution or provider
- No relationship to the donee is required
- Unlimited in amount, separate from §2503(b)
- Tuition only — books, room, and board do not qualify
- Medical includes insurance premiums paid directly
Common patterns and traps
The Future-Interest Disqualifier
The annual exclusion under §2503(b) is available only for gifts of a present interest — an unrestricted right to immediate use, possession, or enjoyment of the property or its income. Gifts to a trust where the beneficiary cannot currently access principal or income are future interests and consume lifetime BEA from dollar one. Crummey powers (a temporary withdrawal right) cure this by converting the gift into a present interest, which is why irrevocable life insurance trusts use them.
An answer choice claims the full transfer to a contingent or restricted trust qualifies for the annual exclusion, ignoring that beneficiaries lack present access to the funds.
The Per-Donor Cap Confusion
Some candidates believe the annual exclusion is a single ceiling on what a donor can give in a year. It is not. The $19,000 (2025) applies per donee, so a donor with five children can transfer $95,000 in one year using only annual exclusions. Gift-splitting under §2513 doubles each exclusion when the donor's spouse consents on Form 709.
A wrong choice computes the taxable gift by subtracting only one $19,000 exclusion from the donor's total annual giving, regardless of how many recipients there were.
The Portability-Without-Filing Trap
DSUE does not transfer automatically. The executor of the first-to-die spouse must file a complete and timely Form 706 making the portability election, even if the estate is well below the filing threshold and owes no tax. Rev. Proc. 2022-32 allows a late election within five years of death for non-filing estates, but missing both deadlines forfeits DSUE permanently.
An answer choice assumes the surviving spouse automatically inherits the deceased spouse's unused BEA without any executor action, ignoring the affirmative election requirement.
The Tuition-and-Medical Misclassification
Direct payments of tuition or medical care under §2503(e) are not gifts at all and are unlimited. The fatal mistake is paying the donee, who then pays the school or hospital — that intermediate step destroys the exclusion and creates a regular gift. The payment must flow directly from the donor to the qualifying institution or care provider.
A wrong choice treats a check given to the grandchild that the grandchild then endorses to the university as qualifying under §2503(e).
The Non-Citizen Spouse Limitation
The unlimited marital deduction under §2523(a) requires the donee spouse to be a U.S. citizen at the time of the gift. For a non-citizen spouse, §2523(i) substitutes an enhanced annual exclusion ($190,000 in 2025) instead of unlimited deduction. The same limitation applies at death under §2056(d), where a Qualified Domestic Trust (QDOT) is required to defer estate tax for a non-citizen surviving spouse.
An answer choice applies the unlimited marital deduction without checking the donee spouse's citizenship status.
How it works
Picture Maria, who in 2025 transfers $50,000 outright to her adult son. The first $19,000 falls under the annual exclusion of §2503(b), leaving a $31,000 taxable gift. Maria owes no tax now because the $31,000 reduces her lifetime BEA — but she must file Form 709 to report it. If Maria's spouse, Luis, consents to gift-splitting under §2513, the couple is treated as each making a $25,000 gift, so two $19,000 exclusions apply and only $12,000 from each spouse reduces their respective BEAs. If Maria instead pays $50,000 directly to her son's university for tuition, §2503(e) treats the payment as a non-gift entirely — no exclusion is consumed, no Form 709 is filed, and Maria's BEA is untouched. The §2503(e) exclusion is layered on top of §2503(b), so Maria could still give her son an additional $19,000 in cash that same year.
Worked examples
What is the total amount of taxable gifts Priya must report on her 2025 Form 709 that will reduce her lifetime basic exclusion amount?
- A $21,000
- B $46,000 ✓ Correct
- C $71,000
- D $106,000
Why B is correct: The transfer to Anjali is $40,000 less the $19,000 annual exclusion, yielding a $21,000 taxable gift. The transfer to Vikram is fully covered by his annual exclusion ($0 taxable). The $60,000 direct tuition payment to Stanford qualifies under §2503(e) and is not a gift at all. The $25,000 medical payment fails §2503(e) because it was paid to Anjali (who then paid the hospital) rather than directly to the provider — the entire $25,000 is a gift, reduced by Anjali's remaining $0 of annual exclusion (already used), so $25,000 is taxable. The $30,000 charitable transfer is fully deductible under §2522. Total taxable gifts: $21,000 + $25,000 = $46,000.
Why each wrong choice fails:
- A: This treats the $25,000 medical payment as qualifying under §2503(e), but the payment must flow directly from the donor to the provider — routing it through Anjali destroys the exclusion. (The Tuition-and-Medical Misclassification)
- C: This adds the $25,000 medical payment but treats only one annual exclusion as used, double-counting Anjali's exclusion or failing to apply Vikram's exclusion correctly. (The Per-Donor Cap Confusion)
- D: This includes the $60,000 direct tuition payment as a taxable gift, ignoring that §2503(e) excludes direct payments to educational institutions entirely from gift-tax treatment. (The Tuition-and-Medical Misclassification)
Which of the following is the most accurate advice the CPA should give Yuki?
- A Yuki automatically inherits Hideo's unused exclusion of $13,610,000 because they were married at his death; no further action is required.
- B Yuki has lost access to Hideo's DSUE permanently because the executor did not file Form 706 by the original due date.
- C The executor may still file a late Form 706 under Rev. Proc. 2022-32 to elect portability, provided it is filed on or before the fifth anniversary of Hideo's death. ✓ Correct
- D Portability is unavailable because Yuki's own estate exceeds the BEA; DSUE applies only to estates below the surviving spouse's exclusion.
Why C is correct: Under IRC §2010(c)(5)(A), portability of DSUE requires the executor of the first-to-die spouse to make an affirmative election on a complete and timely Form 706. Rev. Proc. 2022-32 grants automatic relief allowing the executor of an estate not otherwise required to file Form 706 to make a late portability election within five years of the decedent's date of death. Hideo died in March 2024, so the executor has until March 2029 to file a late Form 706 and elect portability of Hideo's DSUE.
Why each wrong choice fails:
- A: DSUE never transfers automatically — the statute requires an affirmative election by the executor on a filed Form 706. Marriage at death is a necessary but not sufficient condition. (The Portability-Without-Filing Trap)
- B: This ignores Rev. Proc. 2022-32, which provides a five-year window for non-filing estates to make a late portability election. The original nine-month deadline is not the absolute cutoff for these estates. (The Portability-Without-Filing Trap)
- D: DSUE is available regardless of the size of the surviving spouse's own estate. There is no rule limiting portability to surviving spouses below their own exclusion threshold.
What is the amount of Dmitri's taxable gift that reduces his lifetime basic exclusion amount?
- A $43,000, computed as $100,000 less three annual exclusions of $19,000 each
- B $81,000, computed as $100,000 less one annual exclusion of $19,000
- C $100,000, because the gift is a future interest that does not qualify for any annual exclusion ✓ Correct
- D $0, because the trust beneficiaries are minors and the §2503(c) minor's trust rules apply automatically
Why C is correct: Under IRC §2503(b), the annual exclusion is available only for gifts of a present interest — an unrestricted right to immediate use, possession, or enjoyment. Because the trustee must accumulate income and principal until each beneficiary reaches age 30 and there are no Crummey withdrawal rights, each grandchild has only a future interest. The full $100,000 is a taxable gift that reduces Dmitri's lifetime BEA. To qualify under §2503(c), the trust would need to permit the property and income to be used for the minor before age 21 and to pass to the minor at 21 — neither condition is met here.
Why each wrong choice fails:
- A: This applies three annual exclusions to a future-interest gift. The annual exclusion is unavailable because the grandchildren have no present right to the trust property or income. (The Future-Interest Disqualifier)
- B: This applies a single annual exclusion as if the trust were one donee, but the more fundamental problem is that future-interest gifts get no annual exclusion at all. (The Future-Interest Disqualifier)
- D: §2503(c) does not apply automatically — the trust must permit current use of property and income before age 21 and require distribution at 21. Distribution at age 30 with mandatory accumulation fails both conditions. (The Future-Interest Disqualifier)
Memory aid
PALMS — Present interest, Annual per-donee, Lifetime BEA reduces, Marital unlimited, Split with spouse via §2513.
Key distinction
The annual exclusion under §2503(b) requires a present interest and applies per donee per year, while the lifetime BEA under §2010(c) is a single cumulative pool that is reduced only by gifts above the annual exclusion — never by gifts within it.
Summary
Apply the annual exclusion first per donee, then reduce the lifetime BEA only by the excess, and remember that marital, charitable, and §2503(e) tuition/medical transfers consume neither.

What is estate and gift tax on the CPA Exam?
The federal transfer tax system under IRC §§2001–2801 imposes a unified gift and estate tax on lifetime and testamentary transfers, with a single cumulative basic exclusion amount (BEA) shared across both. Under IRC §2503(b), each donor may exclude the first $19,000 (2025 indexed amount) per donee per year before any taxable gift arises; gifts above that reduce the donor's lifetime BEA before any tax is owed. Under IRC §2010(c)(5), a surviving spouse may elect portability of the deceased spouse's unused exclusion (DSUE) by filing a timely Form 706. The marital deduction (IRC §2523 for gifts; §2056 for estates) and the charitable deduction allow unlimited transfers to a U.S.-citizen spouse or qualifying charity without using exclusion.
