Quick Answer
An unused charitable carry-forward is lost at death for tax year 2025 and 2026. The deceased person’s leftover carryover can only be used on the final Form 1040 covering the year of death. Any amount not used there expires — it does not pass to heirs, the estate, or a surviving spouse.
The harder truth sits underneath that simple rule. When a person gives more to charity than the law lets them deduct in one year, the extra amount carries forward for up to five years under Internal Revenue Code §170. But death acts like a gate. The clock stops on the final return, and whatever the person could not use in that last year simply vanishes, with no second chance for anyone left behind.
That detail matters most for families settling an estate and for surviving spouses who assume the deduction “stays in the family.” It does not. A six-figure gift of appreciated stock can leave tens of thousands of dollars in unused deductions on the table the moment the donor dies, and the survivor often learns this only after the return is filed and the chance is gone.

What a Charitable Carry-Forward Actually Is
A charitable carry-forward (also called a carryover) is the unused part of a charitable deduction that you could not claim in the year you gave, pushed into future tax years. The tax code caps how much you can deduct in a single year based on your adjusted gross income (AGI). When your giving tops that cap, the law does not erase the excess — it lets you carry it forward for up to five tax years under IRC §170(d).
The cap depends on what you give and who receives it. For tax year 2025, cash gifts to public charities are deductible up to 60% of AGI, while gifts of appreciated property (like long-held stock) to public charities are generally capped at 30% of AGI. When a gift exceeds these ceilings, the leftover becomes a carryover that keeps its original character — a 30% gift stays a 30% gift in future years.
Here is why the carryover exists at all. Congress wanted to reward large gifts without letting one huge donation wipe out a person’s entire tax bill in a single year. The carryover is the compromise: you get the full benefit, but spread across time. The consequence of this design is the trap this article addresses — time runs out when you die.
A common misconception is that a carryover is “money in the bank” that you own forever. It is not. It is a time-limited tax attribute, and like a net operating loss or capital loss carryover, it expires if unused — either after five years or, more abruptly, at death.
What you should do about it: if you are still living and sitting on a large carryover, track it every year on your Schedule A worksheet and use it as fast as the AGI limits allow. Speed is protection.
The Five-Year Window
The carryover lasts five tax years after the year of the original gift, used in order — current-year gifts first, then the oldest carryover next. If you give a large gift in 2025 and cannot fully deduct it, you have 2026 through 2030 to use the rest. After the fifth year, any remaining amount is lost forever, even while you are alive.
The ordering rule matters because it can quietly starve your oldest carryovers. Each year, your current giving uses up your AGI room first, and only the leftover room absorbs the carryover. In a year with heavy new giving, your old carryover may not move at all, burning a year off its five-year life.
The consequence is silent expiration. Many donors assume they will “get to it eventually,” then watch a carryover age out unused. The fix is deliberate: in years you want to drain a carryover, pause new large gifts so the AGI room flows to the old amount.
The Core Rule: Carryovers Die With the Donor
When a taxpayer dies, the final Form 1040 covers January 1 through the date of death. That final return is the last stop for the carryover. The person’s executor or surviving spouse can claim the carryover on that return up to the deceased’s AGI limits for the year of death — and not one dollar more. Whatever cannot be absorbed there is permanently lost.
This is not a quirk of one ruling. It is settled tax law confirmed across decades of guidance: unused charitable contribution carryovers, net operating losses, capital loss carryovers, and most personal tax credits all terminate at death. The assets that created the deduction pass to heirs; the tax benefit does not.
The reason is structural. A charitable deduction offsets that person’s taxable income. Once the person is gone, there is no more personal income for the deduction to offset, and the deduction has no separate life of its own. The estate is a different taxpayer with its own rules, and it cannot inherit an individual’s personal income-tax attributes.
A widespread misconception is that the estate (filing Form 1041) can “pick up” the dead person’s leftover charitable carryover. It cannot. The estate may take its own charitable deductions for gifts it makes under §642(c), but the decedent’s personal §170 carryover does not flow to the estate. The Tax Adviser confirms that if the taxpayer dies before using the carryover, the unused amount is lost.
What you should do about it: when someone with a known large carryover is seriously ill, talk to a CPA about accelerating income into the final year (for example, Roth conversions) so the carryover has more income to offset before it disappears.
The Surviving-Spouse Exception (and Its Hard Limit)
There is one partial escape, and it applies only to married couples. When spouses give jointly and build a joint carryover, the law splits that carryover between them as if they had filed separately. Under Treasury Regulation §1.170A-10(d)(4), each spouse “owns” the share of the carryover attributable to their own gifts and income.
When one spouse dies, the survivor keeps their own share of the carryover and can keep using it on future returns. But the deceased spouse’s share gets one final chance — the joint return for the year of death (or the decedent’s separate final return) — and then it is gone. The survivor cannot absorb the dead spouse’s portion in any later year.
The consequence is a split outcome that surprises most families. Greenleaf Trust explains that for joint filers, an allocation of the carryover to the survivor is allowed only for the year of death; after that year ends, the decedent’s piece is lost. Professor Russell James of Texas Tech puts it bluntly: carryover charitable deductions are simply lost at death to the extent they belonged to the decedent.
A common misconception is that “we filed jointly, so the whole carryover is ours together, and the survivor keeps all of it.” Wrong. The regulation forces an allocation, and only the survivor’s allocated share survives. The federal rule at 26 CFR §1.170–3 states the deceased spouse’s unused portion may not be treated as paid in the year of death or later except on the final joint or separate return.
What you should do about it: file a joint return for the year of death when it is allowed and beneficial, and have the preparer calculate the spousal allocation carefully so you claim every dollar of the decedent’s share before it expires.
How the Spousal Split Is Calculated
The allocation treats each spouse as if they had filed separately for the year the carryover arose. The carryover is divided based on whose contributions and whose income generated the excess. If the deceased spouse made the gift from their own assets, most of the carryover is theirs — and most of it dies with them.
This is why the survivor’s “rescue” is often small. If a husband donated his own appreciated stock and died with a large carryover, the wife may inherit only a thin slice of it, because the carryover traces to his gift and his income. The math, not the marriage, controls the split.
The consequence of getting this allocation wrong is either an overstated deduction (which the IRS can disallow, with interest and penalties) or an understated one (leaving money on the table). Because the calculation is technical, this is a clear point to bring in a CPA who can document the split correctly.
A Fully Worked Example (Real Dollars)
Numbers make this concrete. Below is a step-by-step example you can copy for tax year 2025, using a single (unmarried) donor so the spousal rule does not muddy the math.
Margaret, age 74 and single, donates $600,000 of appreciated stock she has held for 20 years to her local hospital foundation in 2025. Her AGI for 2025 is $200,000. Gifts of appreciated property to a public charity are capped at 30% of AGI.
- Year 2025 AGI: $200,000.
- 30%-of-AGI limit for appreciated property: $200,000 × 30% = $60,000 deductible in 2025.
- Carryover created: $600,000 − $60,000 = $540,000 carried into 2026.
Now assume Margaret dies in March 2026. Her executor files a final Form 1040 covering January 1 to her date of death. Her 2026 AGI on that short final-year return is $50,000 (a few months of pension and investment income).
- Final-year (2026) AGI: $50,000.
- 30%-of-AGI limit: $50,000 × 30% = $15,000 deductible on the final return.
- Carryover used on final return: $15,000.
- Carryover remaining: $540,000 − $15,000 = $525,000.
- Amount permanently lost at death: $525,000.
At a 24% marginal rate, that lost $525,000 deduction represents roughly $126,000 in tax savings that simply vanished. The gift was real and generous, but the tax benefit died with Margaret because the AGI limits never gave her enough room to use it.
The lesson in the math: large gifts of appreciated property are especially dangerous for carryover loss at death because the 30% cap is low. The fix is planning the gift’s timing and size against realistic AGI and life expectancy — ideally years before death.
Which Situation Applies to You?
The answer changes depending on who you are and how the gift was made. Find your situation below and read the matching section above.
- You are a surviving spouse who filed jointly. You keep only your allocated share of the carryover; the decedent’s share is usable only on the year-of-death return. See “The Surviving-Spouse Exception.”
- You are the executor of a single (unmarried) person. The entire carryover is usable only on the final Form 1040, then lost. See “Carryovers Die With the Donor.”
- You are settling an estate that wants to give to charity. The estate uses its own §642(c) deduction on Form 1041; the decedent’s personal §170 carryover does not transfer. See the core-rule section.
- You are still living with a large carryover. Focus on using it fast and on death-planning. See “What to Do Next.”
- Your gift was made by will (a bequest). That is an estate-tax charitable deduction on Form 706, a different rule entirely. See the FAQs.
Three Common Scenarios
Each scenario below shows the situation and its tax result.
Scenario 1: Single donor with a large stock gift
| Situation | Tax Result |
|---|---|
| Single person gives appreciated stock far above the 30% AGI cap, then dies two years later | Only the final-year 30%-of-AGI amount is deductible; the rest is permanently lost |
Scenario 2: Married couple, one spouse’s gift
| Situation | Tax Result |
|---|---|
| Husband donates his own assets, builds a joint carryover, then dies | Wife keeps her small allocated share; husband’s larger share is usable only on the year-of-death joint return |
Scenario 3: Estate wants to honor the deceased’s wishes
| Situation | Tax Result |
|---|---|
| Family wants the estate to “use up” the decedent’s leftover carryover | Not allowed; the estate gets only its own §642(c) deduction for gifts it actually makes |
Three Named Examples
Robert, single, Texas. Robert gives $400,000 cash to his church in 2025 when his AGI is $150,000. Cash gifts cap at 60% of AGI, so he deducts $90,000 in 2025 and carries $310,000 forward. He dies in early 2026 with a final-year AGI of $40,000. He deducts only $24,000 (60% × $40,000) on his final return, and $286,000 is lost.
Linda and James, married, California. James donates his own appreciated land in 2025, creating a $300,000 joint carryover. He dies in 2026. Because the gift traces to James’s assets, the allocation gives Linda only about $40,000 of the carryover to keep; the remaining roughly $260,000 is usable only on the 2026 joint return and is otherwise lost.
The Estate of Carol, Florida. Carol dies in 2025 with a $200,000 unused charitable carryover. Her children, as executors, want the estate to claim it on Form 1041. Their CPA explains the carryover cannot transfer to the estate; only Carol’s final Form 1040 can use any of it. The estate may make and deduct its own charitable gifts, but Carol’s personal carryover is gone.
The 2026 Wrinkle: The New 0.5% AGI Floor
A new rule changes the carryover math starting in tax year 2026, so anyone dealing with a death in 2026 or later must factor it in. Under the One Big Beautiful Bill Act (OBBBA), itemizers can now deduct charitable gifts only to the extent they exceed 0.5% of AGI. The first 0.5% of AGI in giving is simply not deductible.
This floor is effective for tax years beginning in 2026 and is a permanent change. For example, a taxpayer with $400,000 AGI who gives $20,000 loses the first $2,000 of the deduction to the floor, per Taft Law’s illustration. The 60%-of-AGI cap on cash and the 30% cap on appreciated property still apply above the floor.
The floor interacts with carryovers in two important ways. First, carryovers from gifts made before January 1, 2026 are not subject to the 0.5% floor when used in later years. Second, post-2025 carryovers used in a future year are subject to that year’s floor, which can shrink how much of the carryover actually helps — including on a final return.
The consequence for death planning is that the new floor gives the final-year deduction even less reach in 2026 and beyond, making carryover loss at death slightly worse. The fix is the same: use carryovers quickly and plan large gifts around realistic income.
Does Your State Follow This Rule?
Start with the federal rule, then check your state, because states do not automatically copy federal law. Most states that allow an itemized charitable deduction generally follow the federal carryover and death treatment, but conformity varies and some states cap or disallow the deduction entirely.
Nine states have no broad personal income tax at all — including Florida, Texas, Washington, Nevada, South Dakota, Wyoming, Alaska, Tennessee, and New Hampshire (which taxes only certain investment income, phasing out). In those states, the federal carryover-at-death question is the only one that matters for income tax, because there is no state charitable deduction to lose.
In income-tax states, the divergence shows up in the details. Some states use federal taxable income as a starting point and inherit the federal carryover rules automatically; others have their own charitable rules, caps, or addbacks. The consequence of assuming your state mirrors the IRS is an incorrect state return and possible penalties.
What you should do about it: confirm your state’s treatment on your state department of revenue’s charitable-deduction page before filing the final state return, and never use the federal carryover figure as a stand-in for the state amount without checking.
How to Claim the Final-Year Deduction (Form Walkthrough)
The carryover is claimed on Schedule A (Form 1040) attached to the decedent’s final Form 1040 for the year of death. The executor, administrator, or surviving spouse signs and files this return. Learn the line-by-line mechanics in our guide on how to fill out Schedule A and the broader final Form 1040 process.
- Step 1 — Identify the carryover. Pull the carryover amount and its character (cash vs. appreciated property, 60% vs. 30%) from the prior year’s Schedule A carryover worksheet.
- Step 2 — Compute the final-year AGI limit. Apply the correct percentage (60%, 30%, or 20%) to the decedent’s AGI on the final return.
- Step 3 — Enter the allowed amount on Schedule A in the charitable contributions section, current-year gifts first, then carryover.
- Step 4 — Mark the return as final. Write “DECEASED,” the name, and date of death across the top, per IRS final-return guidance.
- Step 5 — Keep records. Retain the appraisal (for property over $5,000), the Form 8283 noncash gift form, and contribution receipts.
The deadline is the standard one: the final Form 1040 is due April 15 of the year after death (April 15, 2026, for a 2025 death), with a six-month extension available on Form 4868. Missing the deadline can forfeit the deduction and trigger late-filing penalties. A straightforward final return may cost a few hundred dollars to prepare; an estate with large carryovers and property gifts often runs $1,000 or more in professional fees — money well spent to capture a five- or six-figure deduction.
Mistakes to Avoid
- Assuming the carryover passes to heirs. It does not; the excess is lost, costing the family the full tax value of the unused deduction.
- Letting the estate try to claim the decedent’s §170 carryover on Form 1041. The IRS will disallow it, with interest and possible penalties.
- Filing separately in the year of death when joint is better. This can shrink the AGI room and waste part of the decedent’s carryover.
- Ignoring the spousal allocation. Overstating the survivor’s share invites an IRS adjustment; understating it leaves deductions unused.
- Forgetting Form 8283 for property gifts over $500. Missing this form can disallow the entire noncash deduction.
- Skipping the qualified appraisal for property over $5,000. Without it, the IRS can deny the deduction outright.
- Treating the 2026 carryover like the old rules. Forgetting the new 0.5% floor on post-2025 gifts can overstate the deduction.
- Assuming the state mirrors federal. This produces a wrong state return and possible state penalties.
Do’s and Don’ts
- Do use carryovers as fast as the AGI limits allow — speed protects them from death and the five-year expiration.
- Do file the final Form 1040 promptly and mark it “DECEASED,” because the deadline is firm and the deduction window closes with it.
- Do calculate the spousal allocation carefully, since only the survivor’s share survives beyond the year of death.
- Do consider accelerating income (like Roth conversions) into the final year, so the carryover has more income to offset.
- Do keep every receipt, appraisal, and Form 8283, because the IRS can deny undocumented gifts.
- Don’t assume the carryover is “money in the bank” — it is a time-limited attribute that expires.
- Don’t let the estate claim the decedent’s personal carryover, because it is not transferable.
- Don’t wait until April to discover the rule, since planning options end at death.
- Don’t mix up the income-tax carryover with an estate-tax bequest deduction; they are different rules on different forms.
- Don’t guess your state’s treatment — confirm it, because conformity genuinely varies.
Pros and Cons of the Carryover Rule
- Pro: The carryover lets generous donors deduct the full value of large gifts over time, not just in one capped year.
- Pro: The five-year window gives flexibility to match deductions to higher-income years.
- Pro: The spousal allocation preserves at least the survivor’s own share of a joint carryover.
- Pro: Pre-2026 carryovers escape the new 0.5% floor, a meaningful break for older large gifts.
- Pro: The rule rewards lifetime giving with a real, bankable tax benefit while you are alive to use it.
- Con: Death permanently destroys the unused carryover — the single biggest weakness for large donors.
- Con: Low AGI caps (especially 30% for property) make full use hard for big gifts.
- Con: The deceased spouse’s share dies even for married couples, surprising many survivors.
- Con: The estate cannot rescue the carryover, so heirs get no benefit from the donor’s generosity.
- Con: The new 0.5% floor further erodes the value of post-2025 carryovers, including on final returns.
When to Call a Professional
This is educational information, not legal or tax advice for your specific situation. Bring in a CPA, tax attorney, or estate attorney when the carryover is large, when gifts involve appreciated property or appraisals, when a spouse has died with a joint carryover, or when an estate (Form 706 or 1041) is involved. That help typically includes calculating the spousal allocation, planning income acceleration before death, and documenting property gifts to survive IRS scrutiny.
What to Do Next
- Locate the carryover on the most recent Schedule A carryover worksheet, and note its dollar amount and character.
- Estimate the final-year AGI and apply the correct percentage cap to see how much can be saved before it is lost.
- Decide on filing status for the year of death (joint is often best for a surviving spouse) before April 15 of the following year.
- Gather records — receipts, Form 8283, and any qualified appraisal for property over $5,000.
- Mark the final Form 1040 “DECEASED” and file it (or extend with Form 4868) by the deadline.
- Call a CPA or estate attorney now if the carryover is large or property is involved — planning options end at death, so move early.
FAQs
Does a charitable carryover transfer to my heirs when I die?
No. An unused charitable carryover is a personal tax attribute that ends at death. It can be used only on the decedent’s final Form 1040, and any remaining amount is permanently lost — heirs cannot use it.
Can the estate claim the deceased person’s leftover charitable carryover?
No. The estate (Form 1041) cannot inherit the decedent’s personal §170 carryover. The estate may deduct only its own charitable gifts under §642(c) for contributions it actually makes from estate income.
How long does a charitable carryover last while I’m alive?
Five tax years. Excess charitable contributions carry forward for up to five years under IRC §170(d). After the fifth year, any unused amount expires and is lost forever, even while you are living.
What happens to a joint carryover when one spouse dies?
The survivor keeps only their allocated share. Under Reg. §1.170A-10(d)(4), the carryover is split between spouses. The deceased spouse’s share is usable only on the year-of-death return, then it is lost.
Can a surviving spouse use the deceased spouse’s carryover in later years?
No. The decedent’s allocated share can be claimed only on the year-of-death joint or final separate return. After that year ends, the survivor cannot use the deceased spouse’s portion in any future year.
What form claims the carryover on the final return?
Schedule A (Form 1040). The carryover is reported in the charitable contributions section of Schedule A, attached to the decedent’s final Form 1040 for the year of death, subject to that year’s AGI limits.
When is the final Form 1040 due after someone dies?
April 15 of the following year. For a 2025 death, the final return is due April 15, 2026, with a six-month extension available via Form 4868. Missing the deadline can forfeit the deduction.
Does the new 2026 0.5% floor affect older carryovers?
No. Carryovers from gifts made before January 1, 2026 are not subject to the 0.5% AGI floor when used in later years. Only post-2025 carryovers face the floor in the year they are used.
Is a charitable bequest in a will the same as an income-tax carryover?
No. A bequest is an estate-tax charitable deduction claimed on Form 706, not an income-tax deduction. It follows different rules and is separate from the lifetime §170 income-tax carryover discussed here.
Do all states follow the federal carryover-at-death rule?
No. State treatment varies. Nine states have no broad income tax, so no state deduction exists. Income-tax states may follow federal rules or impose their own caps — confirm with your state’s department of revenue.
Can I avoid losing a carryover by giving everything in one year?
Not entirely. Large one-year gifts often exceed the AGI caps (60% cash, 30% property), creating the very carryover that risks dying with you. Spreading gifts across years and using carryovers quickly is safer.
What if the decedent had no income in the year of death?
The carryover is essentially lost. With little or no AGI on the final return, there is almost no room to absorb the carryover, so nearly all of it expires unused at death.
