If a charitable gift was larger than the percentage of adjusted gross income the tax code lets you deduct in one year, the 5-year charitable contribution carryover lets you deduct the excess over the next five tax years. The unused amount keeps the same AGI ceiling it had when you made the gift, gets applied after each new year’s current contributions, and expires permanently if any balance remains after the fifth carryover year.
What Creates a Carryover in the First Place
A carryover exists only because annual deduction ceilings cap how much of a gift you can write off in the year you made it. Those ceilings are set as a percentage of AGI, and they depend on what you gave and who received it:
- 60% of AGI for cash contributions to public charities (churches, hospitals, universities, most community foundations).
- 50% of AGI for non-cash contributions other than capital gain property to those same public charities, and when a donor elects to reduce an appreciated property gift to its cost basis.
- 30% of AGI for long-term capital gain property given to public charities at fair market value, for cash gifts made “for the use of” a public charity rather than directly to it, and for cash or ordinary-income property given to private non-operating foundations.
- 20% of AGI for capital gain property given to private non-operating foundations or other organizations that aren’t public charities.
Anything above the ceiling that applies to your gift becomes a carryover. If your AGI is $200,000 and you gave $150,000 in cash to a public charity, your current-year deduction is $120,000 (60% of $200,000), and $30,000 carries forward.
Ceilings stack in a set order within a single year: 60%/50% contributions come off first, then 30%, then 20%. Lower-percentage categories only fill whatever AGI room is left. And none of this matters in a given year unless you itemize on Schedule A; if the standard deduction beats your itemized total, you get no current-year deduction, though the carryover rules still apply going forward.
How the Five-Year Clock Works
The clock starts the year after the gift. A donation made in 2026 that produced excess can be deducted in 2027 through 2031. Anything still unused after 2031 is gone.
In each carryover year, the deduction follows a strict sequence. You calculate that year’s AGI ceiling using that year’s income, apply all of that year’s new charitable contributions against it, and only then let carryover amounts absorb whatever ceiling capacity is left over. Current-year gifts always go first.
When you’re carrying balances from more than one prior year, the oldest one goes first. The statute requires first-in, first-out ordering, so a 2025 carryover has to be fully used before any 2026 carryover comes into play. That protects the oldest balances from hitting the five-year deadline while newer ones sit idle.
The Carryover Keeps Its Original Character
The percentage bucket a contribution falls into doesn’t change with time. A 30%-limit gift of appreciated stock stays a 30%-limit deduction in year three of the carryover, measured against that year’s AGI. A 60%-limit cash gift stays a 60%-limit deduction. You recalculate the dollar ceiling each year using current income, but you never reclassify the gift itself.
This is why income swings matter. If the carryover was created in a lean year and your income rises later, the higher AGI produces a bigger dollar ceiling and you absorb the balance faster. If your income falls, you may not absorb much at all, and the five-year window keeps running whether you use the room or not.
Appreciated Property: The Most Common Carryover Source
Donating long-term appreciated assets like publicly traded stock or real estate to a public charity is efficient, and it’s also where carryovers show up most often, because the 30% ceiling is tight compared to the 60% cash ceiling.
The default is fair market value deducted against a 30%-of-AGI limit, with excess carrying forward five years under the standard rules. As an alternative, you can elect to reduce the deduction from fair market value down to cost basis, which lifts the ceiling from 30% to 50% of AGI. The math usually favors keeping fair market value, because the full appreciated amount at 30% typically produces a larger deduction over the carryover life than basis at 50%. The election makes sense mainly if you expect income to drop sharply and want to claim more of the deduction now.
The election is all-or-nothing for the year. Make it, and every capital gain property gift you made that year to public charities gets reduced to basis. You can’t apply it selectively.
Capital gain property given to a private non-operating foundation is stricter still: the ceiling is the lesser of 20% of AGI, or 30% of AGI reduced by any capital gain property already claimed under the 30% public-charity limit. Carryovers from these gifts apply last in the ordering, and they still expire after five years.
2026 Rule Changes That Affect the Carryover Math
Two provisions in the One Big Beautiful Bill Act change how much of a gift actually reaches the percentage ceiling starting in tax year 2026.
The 0.5% AGI Floor
Individual charitable deductions now apply only to the extent contributions exceed 0.5% of AGI. On $300,000 of AGI, the first $1,500 of giving produces no deduction. Only what’s above that floor enters the percentage-limit calculation, which means for a gift that already exceeds the AGI ceiling, the floor slightly reduces the deductible portion and can push a bit more into the carryover.
New Reduction for High-Income Itemizers
OBBBA permanently repealed the old Pease limitation and replaced it with a reduction that applies to taxpayers whose AGI exceeds the threshold for the top marginal rate. The reduction equals 2/37ths of most itemized deductions, including charitable contributions. It doesn’t change the percentage ceilings that create carryovers, but it does shrink the actual tax benefit of both current-year deductions and carryover amounts once they’re claimed.
Boundary: The Non-Itemizer Deduction
Also starting in 2026, non-itemizers can deduct up to $1,000 ($2,000 for joint filers) of cash contributions to qualifying public charities directly from gross income. Gifts to donor-advised funds and private non-operating foundations don’t qualify. This deduction sits outside the itemized-deduction system and does not generate a carryover or interact with one.
Events That Reduce or End a Carryover
Death of the Donor
A charitable carryover doesn’t survive the donor. It can be claimed on the final return for the year of death, but any remaining balance after that is permanently lost. It cannot pass to the estate or heirs.
For joint filers, the loss is partial. Treasury regulations require that a remaining joint-return carryover be reallocated between the spouses as if they had filed separately in the year of the original contribution. The surviving spouse keeps the portion tied to their own contributions; the deceased spouse’s portion disappears.
Divorce
Divorce triggers the same reallocation. The original contributions are recomputed as though the spouses had filed separately, and each ex-spouse takes the carryover proportional to their own giving. The allocation is set by regulation and can’t be negotiated in the settlement.
Standard-Deduction Years
Switching from itemizing to the standard deduction in one of the five carryover years means no carryover deduction that year. The IRS acknowledges special rules apply here and notes their complexity. The carryover isn’t forfeited outright, but the year still counts against the five-year window. If you itemize again while the window is open, you can resume. Two or three standard-deduction years in a row will quietly eat most of the window with no benefit.
Net Operating Losses
If an NOL zeroes out taxable income, no charitable deduction is allowed that year. For corporations especially, the interaction between charitable carryovers and NOL absorption is intricate, and charitable carryovers can effectively convert into NOL carryovers in some situations. If both are in play, get professional help.
Records You’ll Need for Five Years or More
A carryover is only as good as the paperwork behind it. For each contribution that produced a carryover, keep the original year of the gift, the type of property, the type of recipient, the applicable AGI percentage limit, the amount deducted each year since, and the remaining balance. Without that trail, the IRS can disallow whatever’s left.
For noncash contributions totaling more than $500 in a year, Form 8283 goes with the return for the year of the gift. You also have to file Form 8283 in each carryover year in which you claim a deduction from that gift. Keep the original Form 8283 and the qualified appraisal (required for donations over $5,000) for the full carryover period.
Individuals report the deduction and track balances on Schedule A of Form 1040; the Schedule A instructions include a worksheet for AGI limits and remaining balances. The audit problem that catches most people isn’t aggressive deductions; it’s not being able to reconstruct, three or four years later, how much was used in each intervening year. A spreadsheet updated every filing season handles it.
Corporate Carryovers Work Similarly but With Different Limits
C corporations use the same five-year carryover framework, but their ceiling is 10% of taxable income (computed before the charitable deduction itself, the dividends-received deduction, NOL carrybacks, and certain other items). For tax years beginning after 2025, OBBBA adds a 1% floor: corporate contributions are deductible only to the extent they exceed 1% of taxable income and don’t exceed the 10% ceiling. Contributions above 10% carry forward for five years, applied in later years under the same 1%-to-10% band and the same first-in, first-out ordering. Qualified conservation contributions to certain farming and ranching organizations, and food inventory donations, get their own higher 15% ceilings with their own five-year carryovers.
