Unified credit
tax year · reviewed 2026-08-20 · Draft for I. Ohu review
The gift tax and the estate tax share one credit, and the word “unified” is the whole point. A gift made in 2026 that exceeds the annual exclusion does not produce a tax bill for most clients, and the reason is not that gifts are exempt — it is that the credit absorbs the tax, and the same credit will not be there at death. Understanding what the credit is, rather than treating it as an allowance that gifts consume, is what makes the rest of the transfer tax system make sense.
The rule
Where the credit comes from. the applicable credit amount that would be in effect under IRC § 2010(c) if the donor died at the end of the calendar year, reduced by the credit allowable for all preceding calendar periods — so it is the same credit as the estate tax credit, drawn on during life (IRC § 2505(a))TY2026 There is no separate gift tax exclusion figure: the number is $15,000,000 for a decedent dying in calendar year 2026 — the IRC § 2010(c)(3)(A) basic exclusion amount as raised by Pub. L. 119-21 § 70106, indexed from calendar year 2026 and rounded to the nearest $10,000 under § 2010(c)(3)(B)TY2026, borrowed from the estate tax and applied through the gift tax rates.
Used once, gone once. The reduction for credit allowable in preceding calendar periods (IRC § 2505(a)(2)) is what makes the credit cumulative. It is not an annual allowance.
And the earlier years are re-priced. the credit allowed for preceding calendar periods is recomputed at the current year's rates rather than the rates that applied when those gifts were made (IRC § 2505(a), closing sentence)TY2026
A ceiling, not a refund. the credit for a calendar year may not exceed the gift tax imposed for that year — it cannot create a refund and unused amounts are not paid out, they simply remain available (IRC § 2505(c))TY2026
Not everyone gets it. the credit is allowed to a citizen or resident of the United States; a nonresident who is not a citizen gets no unified credit against gift tax at all, though the annual exclusion still applies (IRC § 2505(a))TY2026
The tax it is credited against is cumulative too. a tentative tax at the IRC § 2001(c) rates on the aggregate taxable gifts of this year and all preceding calendar periods, less a tentative tax on the aggregate of the preceding periods alone — so each year's gifts are taxed at the marginal rate the cumulative total has reached (IRC § 2502(a))TY2026 That is why a client who used the whole credit twenty years ago pays gift tax at the top rate on the next dollar — the bracket is determined by the running total, not by this year’s gift.
And the imposition itself. imposed for each calendar year on the transfer of property by gift by any individual, resident or nonresident — but not on a nonresident who is not a citizen transferring intangible property, except as IRC § 2501(a)(3) provides (IRC § 2501(a))TY2026
At death, the whole thing is recomputed. in computing the estate tax subtraction for gift tax payable, the rates in effect at death are used in place of the rates in force when the gifts were made, both for the chapter 12 tax and for the IRC § 2505 credit against it (IRC § 2001(g)(1))TY2026 And where the exclusion amount has moved between the gift and the death, the Secretary is directed to prescribe regulations addressing any difference between the basic exclusion amount at the decedent's death and the amount applicable to gifts the decedent made (IRC § 2001(g)(2))TY2026
Current figures
| Item | Rule |
|---|---|
| Basic exclusion amount | $15,000,000 for a decedent dying in calendar year 2026 — the IRC § 2010(c)(3)(A) basic exclusion amount as raised by Pub. L. 119-21 § 70106, indexed from calendar year 2026 and rounded to the nearest $10,000 under § 2010(c)(3)(B)TY2026 |
| Credit amount | the applicable credit amount that would be in effect under IRC § 2010(c) if the donor died at the end of the calendar year, reduced by the credit allowable for all preceding calendar periods — so it is the same credit as the estate tax credit, drawn on during life (IRC § 2505(a))TY2026 |
| Applicable credit amount | the tentative tax that IRC § 2001(c) would produce on the applicable exclusion amount — a credit against tax, not a deduction from the estate, and the reason the exclusion is worth exactly the tax on it and no more (IRC § 2010(c)(1))TY2026 |
| Recomputation of prior periods | the credit allowed for preceding calendar periods is recomputed at the current year's rates rather than the rates that applied when those gifts were made (IRC § 2505(a), closing sentence)TY2026 |
| Ceiling on the credit | the credit for a calendar year may not exceed the gift tax imposed for that year — it cannot create a refund and unused amounts are not paid out, they simply remain available (IRC § 2505(c))TY2026 |
| Citizenship requirement | the credit is allowed to a citizen or resident of the United States; a nonresident who is not a citizen gets no unified credit against gift tax at all, though the annual exclusion still applies (IRC § 2505(a))TY2026 |
| Cumulative computation | a tentative tax at the IRC § 2001(c) rates on the aggregate taxable gifts of this year and all preceding calendar periods, less a tentative tax on the aggregate of the preceding periods alone — so each year's gifts are taxed at the marginal rate the cumulative total has reached (IRC § 2502(a))TY2026 |
| Imposition of tax | imposed for each calendar year on the transfer of property by gift by any individual, resident or nonresident — but not on a nonresident who is not a citizen transferring intangible property, except as IRC § 2501(a)(3) provides (IRC § 2501(a))TY2026 |
| Rates | 40 percent of the excess over $1,000,000, on top of $345,800 — the top bracket of the IRC § 2001(c) unified rate schedule, which every estate large enough to owe tax is entirely insideTY2026 |
| Annual exclusion | $19,000 per donee for calendar year 2026, for gifts other than gifts of future interests (IRC § 2503(b))TY2026 |
| Recomputation at death | in computing the estate tax subtraction for gift tax payable, the rates in effect at death are used in place of the rates in force when the gifts were made, both for the chapter 12 tax and for the IRC § 2505 credit against it (IRC § 2001(g)(1))TY2026 |
| Exclusion difference regulations | the Secretary is directed to prescribe regulations addressing any difference between the basic exclusion amount at the decedent's death and the amount applicable to gifts the decedent made (IRC § 2001(g)(2))TY2026 |
| Estate tax computation | a tentative tax on the sum of the taxable estate and adjusted taxable gifts, reduced by the gift tax that would have been payable on post-1976 gifts under current rates — so lifetime gifts enlarge the base rather than reducing the exclusion arithmetic (IRC § 2001(b))TY2026 |
| Portability | the lesser of the basic exclusion amount, or the applicable exclusion amount of the last deceased spouse reduced by the amount on which the tentative tax was determined under IRC § 2001(b)(1) on that spouse's estate (IRC § 2010(c)(4))TY2026 |
How it works in practice
Explain what the credit is before anything else. Clients arrive believing there is a lifetime allowance that gifts eat into. The mechanics are different and the difference matters: taxable gifts enlarge the base on which tax is computed, and a single credit — measured by the tax on the exclusion amount — is applied against the resulting tax. The two descriptions give the same answer only because the top bracket is flat, which it is for every client this arises for.
Work the computation in the statutory order (IRC § 2502(a)). Aggregate this year’s taxable gifts with all preceding calendar periods, compute a tentative tax on the total, subtract a tentative tax on the preceding periods alone, then apply the § 2505 credit as reduced by credit already used. Skipping the aggregation step gives the right answer only for a client with no gift history.
Ask about gift history before advising on a large gift. The credit reduction in § 2505(a)(2) reaches back to every prior calendar period. A client who made substantial gifts in the 2010s may have far less credit remaining than the current exclusion amount suggests, and only the prior Forms 709 will show it.
Do not treat unused credit as wasted. Section 2505(c) caps the credit at the year’s tax, but the excess is not lost — it simply has not been used, and remains available for later gifts and ultimately at death. There is nothing to elect and nothing to carry forward.
Remember the non-resident alien. A nonresident who is not a citizen has no unified credit against gift tax. The annual exclusion is still available, but the first taxable dollar is taxed. This catches advisers who assume the exclusion amount travels with the taxpayer.
And keep the estate tax in view. a tentative tax on the sum of the taxable estate and adjusted taxable gifts, reduced by the gift tax that would have been payable on post-1976 gifts under current rates — so lifetime gifts enlarge the base rather than reducing the exclusion arithmetic (IRC § 2001(b))TY2026 Gifts made during life reappear in the estate tax base as adjusted taxable gifts; the gift tax already paid or notionally payable is subtracted; and the credit is applied once. Using the credit during life is a timing decision about which tax it shelters, not a way to double it.
The credit that had already been spent
A client made taxable gifts of $9,000,000 in 2019 and paid no gift tax, the credit having absorbed it. In 2026 he wants to give another $8,000,000 and assumes the current exclusion amount covers it.
It does not, because the credit is reduced under § 2505(a)(2) by the credit allowable for preceding calendar periods. His remaining credit corresponds to roughly $6,000,000 of exclusion, so around $2,000,000 of the new gift is exposed, and it is exposed at the top rate — the cumulative computation in § 2502(a) puts the whole of this year’s gift above the bracket thresholds. The current exclusion amount describes the total he may shelter across his life, not the amount available today.
The nonresident donor
A citizen of another country, not resident in the United States, gives United States real property worth $900,000 to her nephew.
The gift is subject to United States gift tax under § 2501(a)(1) — the tax reaches transfers by any individual, resident or nonresident, and the exception in § 2501(a)(2) covers only intangible property. She may use the annual exclusion, but she has no unified credit: § 2505(a) allows it only to a citizen or resident. The tax is payable on essentially the whole gift, which is a result no domestic client ever encounters.
The year with more credit than tax
A client with no gift history makes a taxable gift of $400,000. The tentative tax on it is well below the credit available to her.
She pays no gift tax, and § 2505(c) limits the credit to the tax imposed for the year — so the credit “allowed” for this year is the amount of that tax and no more. The rest is not refunded, not carried forward as a separate item, and not lost: it is simply still there, because next year’s credit is computed afresh under § 2505(a)(1) and reduced only by what was actually allowed.
The rates that changed after the gift
A client made large taxable gifts in the early 1990s, when the top gift tax rate was materially higher than it is now. He dies in 2026 and his executor computes the estate tax.
The subtraction for gift tax payable is not the tax he actually paid. Section 2001(g)(1) requires the rates in effect at death to be used in place of the rates in force at the time of the gifts, for both the chapter 12 tax and the § 2505 credit against it. The executor must recompute, and the recomputed figure will differ from every number on the original Forms 709.
Calling it a lifetime exemption that gifts reduce. Taxable gifts are added to the estate tax base under § 2001(b)(1)(B); the credit is applied once at the end. The shortcut agrees only because the top bracket is flat.
Treating the credit as available afresh each year. Section 2505(a)(2) reduces it by everything allowable in preceding calendar periods.
Forgetting the cumulative rate computation. Section 2502(a) stacks this year’s gifts on top of every preceding period, so the marginal rate reflects a lifetime total, not one year.
Assuming a nonresident alien donor has a credit. Section 2505(a) allows it only to a citizen or resident. The annual exclusion is separate and still applies.
Thinking unused credit is forfeited. Section 2505(c) is a ceiling on what is allowed for the year, not a use-it-or-lose-it rule.
Using the gift tax actually paid in the estate computation. Section 2001(g)(1) requires recomputation at the rates in effect at death.
Expecting a separate gift tax exclusion figure. There is none. Section 2505(a)(1) points at the applicable credit amount under § 2010(c), which is an estate tax provision.
How this has changed
Unification is the historical fact that explains this topic. Before 1977 the gift tax and the estate tax had separate exemptions and separate rate schedules, and gifts were taxed at rates that were lower than the estate tax rates by design. The Tax Reform Act of 1976 merged them into a single rate schedule with a single credit, which is why the gift tax credit provision has to point at an estate tax provision to find its own amount (IRC § 2505(a)(1)).
Since then the credit has moved with the exclusion. Pub. L. 119-21 § 70106 did not amend § 2505 at all — it raised the basic exclusion amount in § 2010(c)(3), and § 2505 picked the change up automatically. The exclusion is now $15,000,000 for a decedent dying in calendar year 2026 — the IRC § 2010(c)(3)(A) basic exclusion amount as raised by Pub. L. 119-21 § 70106, indexed from calendar year 2026 and rounded to the nearest $10,000 under § 2010(c)(3)(B)TY2026 and permanent, having previously been scheduled to fall by half after 2025.
That scheduled reversion produced the one live question this topic still carries. Section 2001(g)(2) directs the Secretary to prescribe regulations dealing with any difference between the basic exclusion amount at death and the amount applicable to gifts already made — the “clawback” problem, which arises whenever a client uses a larger exclusion during life than is available at death. With the higher figure now permanent, the problem has receded rather than disappeared: the statutory direction stands, the exclusion is still indexed, and a future reduction would revive it immediately.
Exam focus
Expect a computation with a gift history. Aggregate all periods, compute the tentative tax on the total, subtract the tentative tax on the prior periods, then apply the credit net of what was used. The distinguishing feature of a well-prepared candidate is doing the aggregation rather than treating the current year in isolation.
Know that there is one credit shared with the estate tax, that § 2505(a)(1) measures it by reference to § 2010(c), and that § 2505(c) caps it at the year’s tax.
The reliable trap is the nonresident alien donor, who has an annual exclusion but no unified credit. Expect it as an “all of the following except” item.
Check yourself
1. A donor used credit corresponding to $5,000,000 of exclusion on gifts in prior years. How much credit is available this year?
Answer: The applicable credit amount that would apply under IRC § 2010(c) if she died at the end of this year, reduced by the credit allowable for all preceding calendar periods (§ 2505(a)) — so the credit corresponding to the current basic exclusion amount less the $5,000,000 already used.
2. A nonresident who is not a citizen of the United States gives United States real property to a friend. Is a unified credit available?
Answer: No. IRC § 2505(a) allows the credit to a citizen or resident of the United States only. The annual exclusion under § 2503(b) remains available.
3. In a year in which the credit exceeds the gift tax, what happens to the excess?
Answer: Nothing is refunded or carried forward as a separate item. IRC § 2505(c) limits the credit allowed to the tax imposed for the year; the unused exclusion simply remains available, because each year’s credit is computed afresh and reduced only by amounts actually allowed.
4. How is this year’s gift tax rate determined for a donor with substantial prior gifts?
Answer: By the cumulative total. IRC § 2502(a) computes a tentative tax on the aggregate of this year’s taxable gifts and all preceding calendar periods and subtracts a tentative tax on the preceding periods alone, so this year’s gifts are taxed at the marginal rates the running total has reached.
5. An executor is computing the subtraction for gift tax payable on gifts made when rates were higher. Which rates apply?
Answer: The rates in effect at the decedent’s death. IRC § 2001(g)(1) substitutes them for the rates in force when the gifts were made, both for the chapter 12 tax and for the § 2505 credit against it.
Change log
- Initial draft. Sets out the IRC § 2505 credit as one credit shared between the two taxes — its measurement by reference to § 2010(c), the reduction for credit allowed in preceding calendar periods, the § 2505(c) ceiling at the year's tax, and the denial to a nonresident who is not a citizen — together with the cumulative computation in § 2502(a) and the recomputation at death rates required by § 2001(g)(1).
