Donation tax deduction limits cap what you can write off in a single year at a percentage of your adjusted gross income. The ceiling is 60% of AGI for cash given to a public charity. Lower limits of 50%, 30%, and 20% apply depending on what you give, who receives it, and whether the property has appreciated. And starting in 2026, a new floor removes the first 0.5% of AGI in charitable giving from any deduction at all.
The New 0.5% AGI Floor for 2026
The One Big Beautiful Bill Act introduced a floor on charitable contribution deductions beginning with the 2026 tax year. Only the portion of your total charitable gifts above 0.5% of your AGI counts toward your deduction. If your AGI is $100,000, the first $500 of donations produces zero tax benefit. Anything above that stays deductible, subject to the percentage caps below.
The floor applies regardless of how you donate or which qualifying organization receives the gift. It effectively wipes out the deduction for small annual giving in some households, which catches moderate-income donors off guard.
Percentage Caps by Gift Type and Recipient
The overall ceiling on your charitable deduction is 60% of AGI, but that applies only to cash gifts to public charities. Other combinations trigger lower limits.1Internal Revenue Service. Publication 526 – Charitable Contributions
- Cash to a public charity: 60% of AGI. This is the highest limit and covers gifts by check, credit card, or electronic transfer to churches, hospitals, schools, and most well-known nonprofits.
- Non-cash property that hasn’t appreciated, given to a public charity: 50% of AGI. Used clothing, furniture, and similar items sit here.
- Appreciated capital gain property to a public charity: 30% of AGI. Stocks, real estate, or other assets held longer than one year that have gone up in value fall here when you deduct at fair market value.
- Cash to a private foundation: 30% of AGI.2Internal Revenue Service. Private Operating Foundations
- Appreciated capital gain property to a private foundation: 20% of AGI. This is the lowest percentage in the system.1Internal Revenue Service. Publication 526 – Charitable Contributions
When you give to both public charities and private foundations in the same year, contributions to public charities are applied first. Private foundation gifts then use only whatever room remains under the overall ceiling. Consider someone with an AGI of $200,000 who gives $110,000 in cash to a public charity (within the 60% limit of $120,000) plus $30,000 to a private foundation. The foundation gift may be partially limited because total deductions across all categories still cannot exceed 60% of AGI.
Short-term holdings work differently from the appreciated-property rules above. If you held an asset for one year or less before donating it, your deduction is limited to your cost basis rather than the current market value, no matter how much the asset has gone up.
The Cost Basis Election for Appreciated Property
If the 30% cap on appreciated property is too restrictive for your giving plans, you can elect to deduct only your original cost basis rather than fair market value. Making that election raises your deduction limit to 50% of AGI for the year.3Office of the Law Revision Counsel. 26 U.S. Code 170 – Charitable, Etc., Contributions and Gifts The trade-off is direct: a smaller per-share deduction in exchange for a larger total dollar amount you can claim.
The election makes sense mainly when you hold a large position with modest appreciation and want to donate a significant chunk in one year. If the stock has tripled, giving up fair market value treatment for 20 extra percentage points of headroom rarely comes out ahead.
You Have to Itemize for Any of This to Matter
Charitable donations only reduce your tax bill if you itemize on Schedule A. For 2026, the standard deduction is $16,100 for single filers, $32,200 for married couples filing jointly, and $24,150 for heads of household.4Internal Revenue Service. IRS Releases Tax Inflation Adjustments for Tax Year 2026 If your total itemized deductions (charitable gifts, mortgage interest, state and local taxes, and everything else on Schedule A) don’t exceed the standard deduction for your filing status, your charitable contributions add nothing to your tax outcome.
This math matters more than people expect. With standard deductions this high, many households that give regularly still come out ahead taking the standard deduction. The donations aren’t wasted; you just need a strategy, and the bunching approach below is built for exactly this situation.
Carrying Forward What Exceeds the Cap
If your donations exceed the applicable AGI percentage limit, you don’t lose the excess. The unused portion carries forward for up to five additional tax years.5Office of the Law Revision Counsel. 26 USC 170 – Charitable, Etc., Contributions and Gifts Each future year applies the same percentage limits based on that year’s AGI. Current-year contributions are applied first; only after those are accounted for does any remaining room absorb the carryover, on a first-in, first-out basis.
Any carryover still unused after five years expires permanently. That risk is real for retirees who donate heavily in their final working year and then watch their AGI drop. If you’re planning an unusually large gift, timing it against expected income is one of the few situations where a tax professional pays for itself.
Bunching to Get Past the Standard Deduction
Because the 2026 standard deduction is $16,100 for single filers and $32,200 for joint filers, many households with moderate charitable giving never clear the itemizing threshold. Bunching addresses this by concentrating two or more years of donations into a single tax year. You itemize in the year you bunch and take the standard deduction in the off years.
A married couple that normally gives $8,000 per year might give $24,000 every third year instead. Combined with mortgage interest and state and local taxes, that $24,000 could push their total itemized deductions past $32,200. In the two intervening years, they take the standard deduction.
A donor-advised fund makes bunching logistically simple. You contribute cash or assets to an account held by a sponsoring public charity, take the deduction in the year of the contribution, and then recommend grants to specific charities on your own timeline. Because the sponsor is a public charity, your contributions follow the standard public-charity limits: 60% of AGI for cash, 30% for appreciated property.1Internal Revenue Service. Publication 526 – Charitable Contributions The deduction lands when you fund the account, not when the grants eventually reach individual nonprofits.
Which Organizations the Limits Apply To
The percentage caps only matter if the recipient qualifies in the first place. Deductible donations must go to organizations the IRS recognizes as qualified recipients under the tax code. The most common category is the 501(c)(3) organization, which includes religious institutions, schools, hospitals, and publicly supported charities.6Internal Revenue Service. Exempt Organization Types Federal, state, and local government bodies also qualify if your gift is earmarked for a public purpose.5Office of the Law Revision Counsel. 26 USC 170 – Charitable, Etc., Contributions and Gifts
You can verify an organization’s status using the IRS Tax Exempt Organization Search tool.7Internal Revenue Service. Tax Exempt Organization Search Churches, synagogues, mosques, and similar religious organizations sometimes do not appear in the database but qualify by default under the tax code.
Gifts That Never Produce a Deduction
Several common types of giving fall entirely outside the deduction system, so the AGI caps never come into play. You cannot deduct gifts to individuals (even needy ones), political organizations or candidates, most foreign charities, civic leagues, labor unions, chambers of commerce, homeowners’ associations, or social clubs.1Internal Revenue Service. Publication 526 – Charitable Contributions GoFundMe campaigns, money handed directly to someone in crisis, and payments to a hospital designated for a specific patient’s care all fail the deductibility test. The value of your time volunteering is likewise never deductible, no matter how skilled the work.
Quid pro quo gifts are treated as partially deductible. When you receive something in return for a donation, only the amount exceeding the value of what you received counts. Pay $200 for a charity gala where the meal is worth $75, and your deductible amount is $125. The charity must provide a written disclosure statement for any quid pro quo contribution over $75, stating the estimated fair market value of the benefit and the deductible portion.8Internal Revenue Service. Charitable Contributions – Quid Pro Quo Contributions Ask for that disclosure before filing if the charity hasn’t sent one.
