What’s the AGI Limit on a Donor-Advised Fund Deduction? (w/Examples) + FAQs

This article reflects federal rules as of June 2026 and covers tax years 2025 and 2026. State rules vary and are addressed in general terms. Tax law changes — confirm current figures with the IRS or a licensed tax professional before you file.

Quick Answer

For tax year 2025, you can deduct up to 60% of your adjusted gross income (AGI) for cash given to a donor-advised fund, and up to 30% of AGI for long-term appreciated assets like stock. Both limits stay the same in 2026, but a new 0.5%-of-AGI floor now trims the first slice of every deduction.

The Short Version, In Context

When you give to a donor-advised fund (a charitable investment account you fund now and give from later, often called a DAF), the IRS does not let you deduct an unlimited amount in one year. Your deduction is capped as a percentage of your AGI, and that percentage depends on what you give. Cash earns the highest ceiling at 60% of AGI, while long-term appreciated property such as stock is held to 30% of AGI. Anything you cannot use this year is not lost — it carries forward for up to five more years under IRC Section 170.

Two things make 2026 different from 2025, and both shrink the benefit. A brand-new 0.5%-of-AGI floor under the One Big Beautiful Bill Act (OBBBA) disallows the first half-percent of your AGI in giving, and a 35% cap limits the value of the deduction for the highest earners. Donors who gave in 2025 dodged both, which is why so many accelerated gifts into last year. According to DAFgiving360, every itemizer in 2026 must now clear that 0.5% floor before a single dollar of charitable deduction counts.

Donor-Advised Funds, Deconstructed

A donor-advised fund is an account you open at a sponsoring public charity, such as a community foundation or the charitable arm of a brokerage. You contribute cash or assets, take your tax deduction in the year of the gift, and then recommend grants to operating charities over time. The key tax fact is timing: you get the full deduction the year you fund the account, even if the money sits there for years before reaching a working charity. That separation of deduction from distribution is the entire appeal.

Because a DAF sponsor is a public charity under Section 501(c)(3), gifts to it qualify for the most generous AGI limits in the tax code — the same limits that apply to gifts made directly to a church, school, or food bank. This matters because gifts to a private foundation face stricter caps (30% for cash, 20% for appreciated assets). A DAF gives you foundation-like control over timing without the harsher foundation limits.

The deduction is also irrevocable. Once you fund the account, you cannot take the money back, and you cannot receive any personal benefit — no gala tickets, no dinner, no naming-rights perk that has cash value. If you do, the IRS reduces or denies the deduction. Understanding the four moving parts — the asset type, the AGI percentage cap, the new floor, and the carryforward — is what separates a clean deduction from an audited one.

The AGI Percentage Limits, By Asset Type

The single most important rule is that your deduction ceiling depends on what you donate, not just how much. Cash and appreciated property are treated very differently.

Cash Contributions: 60% of AGI

For tax year 2025 and continuing in 2026, cash gifts to a donor-advised fund are deductible up to 60% of your AGI, a limit the OBBBA made permanent according to Taft Law. “Cash” includes check, wire, and credit-card gifts. The consequence of exceeding 60% is not a lost deduction — the excess simply carries forward for up to five years. A common misconception is that the 60% cap was a temporary pandemic-era rule; it is now permanent law. What you should do: if a large cash gift would blow past 60% of your AGI, expect a carryover and plan your next four returns around using it.

Long-Term Appreciated Assets: 30% of AGI

When you donate publicly traded stock, mutual funds, real estate, crypto, or private business interests held more than one year, your deduction is generally the full fair market value, but it is capped at 30% of AGI for tax years 2025 and 2026, as LinkedIn-cited advisor guidance and Accounting Insights explain. The huge upside is that you also avoid capital-gains tax on the appreciation. The consequence of donating short-term assets (held one year or less) is that your deduction drops to your cost basis, not market value. What you should do: confirm your holding period before transferring shares, because one day short of a year can cut your deduction dramatically.

The Stacking Rule When You Give Both

If you give cash and appreciated stock in the same year, the limits do not simply add to 90%. Your total deduction is capped at 60% of AGI overall, and the 30% appreciated-asset limit fits inside that ceiling. In practice, appreciated property is counted first against the 30% limit, and cash can fill the remaining room up to 60%. The consequence of ignoring this is over-claiming, which the IRS will adjust on audit. What you should do: run the math in the order the IRS uses, appreciated assets first, then cash.

The Two New 2026 Rules That Shrink Your Deduction

OBBBA left the percentage caps alone but added two permanent hurdles starting in tax year 2026. Both apply to DAF gifts just like any other charitable gift.

The 0.5%-of-AGI Floor (Effective 2026, Permanent)

Beginning in tax year 2026, itemizers may deduct charitable gifts only to the extent they exceed 0.5% of AGI, per the Greenleaf Trust analysis of new IRC Section 170(b)(1)(I). The first half-percent of your AGI in giving is simply disallowed. The consequence is small for big donors and painful for modest ones. As Taft Law illustrates, a donor with $400,000 AGI who gives $20,000 loses the deduction on the first $2,000 and deducts only $18,000. A common misconception is that you can carry the lost 0.5% forward freely; the disallowed amount can carry over five years, but Fredrikson notes it stays subject to the same floor in future years. What you should do: in 2026, “bunch” several years of giving into one large DAF contribution so a single 0.5% haircut covers many years of grants.

The 35% Deduction-Value Cap (Effective 2026, Top Bracket Only)

For taxpayers in the 37% bracket, OBBBA caps the value of itemized deductions at 35 cents per dollar starting in 2026, as BOK Financial reports. A 37%-bracket donor who once saved $37 per $100 deducted now saves $35. Per PG Calc, this hits only single filers above $640,601 and joint filers above $768,701 of taxable income in 2026. The consequence is a roughly 5% reduction in tax savings for the wealthiest donors. What you should do: high earners who can give in a year before they hit the top bracket, or who already gave in 2025, capture more value.

Which Situation Applies to You?

The right move depends on who you are. Find your row.

You are a high-income donor in the 37% bracket: the 35% cap and the 0.5% floor both apply in 2026. Front-loading or bunching gifts matters most for you.
You had a one-time windfall (business sale, IPO, big bonus): donate long-term appreciated stock to a DAF in the windfall year to offset spiking income, subject to the 30% cap with a five-year carryover.
You are a steady middle-income giver: the 0.5% floor takes a real bite each year, so consider bunching two or three years of gifts into one.
You are a non-itemizer: the percentage caps do not apply to you, but a separate above-the-line deduction of up to $1,000 single / $2,000 joint exists in 2026 — though Taft Law confirms it generally does not cover gifts to a DAF.

Worked Examples With Real Dollar Figures

Numbers make the rules concrete. These are illustrative scenarios, not tax advice for your specific return.

Example 1 — Cash Gift, 2025 (Before the Floor)

Maria has an AGI of $300,000 in 2025 and gives $200,000 cash to her DAF. Her cash cap is 60% of AGI, or $180,000. She deducts $180,000 this year and carries forward the remaining $20,000 for up to five years. No 0.5% floor applies in 2025, so she keeps the full $180,000.

Maria’s 2025 Cash Gift	Result
AGI	$300,000
Cash contributed	$200,000
60% AGI ceiling	$180,000
Deductible this year	$180,000
Carried forward (5 yrs)	$20,000

Example 2 — Appreciated Stock, 2026 (With the Floor)

David has an AGI of $500,000 in 2026 and donates stock worth $200,000 (cost basis $40,000) held three years. His appreciated-asset cap is 30% of AGI, or $150,000. But the 0.5% floor first disallows $2,500 (0.5% of $500,000). His starting deductible figure is $200,000 minus $2,500 = $197,500, still capped at $150,000 this year, with $47,500 carried forward. He also avoids capital-gains tax on $160,000 of appreciation.

David’s 2026 Stock Gift	Result
AGI	$500,000
Stock fair market value	$200,000
0.5% AGI floor disallowed	$2,500
30% AGI ceiling	$150,000
Deductible this year	$150,000
Capital gain avoided	$160,000

Example 3 — Top-Bracket Donor Feels the 35% Cap

Priya is a single filer with $900,000 of taxable income in 2026, placing her in the 37% bracket. She gives $100,000 cash to her DAF. After the 0.5% floor on her AGI removes a slice, her remaining deduction is valued at only 35 cents per dollar, not 37. On a $99,000 net deduction, her tax savings are about $34,650 rather than the $36,630 she would have gotten under the old 37% value — a roughly $1,980 difference.

Priya’s 2026 Top-Bracket Gift	Result
Cash contributed	$100,000
Tax value at old 37%	~$36,630
Tax value at new 35% cap	~$34,650
Lost benefit from cap	~$1,980

The Five-Year Carryforward and Bunching

Any contribution that exceeds your AGI limit is not wasted. Under IRC Section 170, the excess carries forward for up to five tax years, keeping its original character — cash stays subject to the 60% limit, appreciated property to the 30% limit. The consequence of forgetting your carryover is real money left on the table when the five years expire. What you should do: track carryforwards on your tax software or a simple spreadsheet so none lapse unused.

Bunching is the strategy that pairs perfectly with a DAF. Instead of giving $20,000 a year for five years, you give $100,000 to your DAF in one year to clear the standard deduction and the new 0.5% floor once, then recommend $20,000 in grants each year. This concentrates your itemized deductions into a single high-impact year while your charities still receive steady support. In a 2026 world with a yearly 0.5% haircut, bunching means you absorb that haircut once rather than five times.

Form 8283 and How to Claim the Deduction

Cash gifts to a DAF are claimed on Schedule A of Form 1040 as an itemized deduction, with a written acknowledgment from the DAF sponsor required for any gift of $250 or more. There is no special form for cash beyond your receipt and Schedule A.

Noncash gifts are different. If your total noncash contributions exceed $500, you must file Form 8283, Noncash Charitable Contributions, and attach it to your return, per the IRS. Section A covers items valued at $500 to $5,000; Section B covers items over $5,000 and generally requires a qualified appraisal. Publicly traded securities are exempt from the appraisal requirement even above $5,000. The consequence of skipping a required appraisal or a missing Form 8283 is a fully disallowed deduction, even when the gift itself was legitimate — courts have upheld denials over this paperwork alone. What you should do: get the appraisal before you file, attach Form 8283, and keep the DAF acknowledgment letter with your records.

Mistakes to Avoid

Donating short-term assets: stock held one year or less is deductible only at cost basis, slashing your deduction.
Receiving a personal benefit: accepting gala tickets or perks with cash value reduces or voids the deduction.
Skipping Form 8283: noncash gifts over $500 without the form mean the IRS denies the entire deduction.
Missing the qualified appraisal: noncash gifts over $5,000 (other than publicly traded stock) require an appraisal or the deduction is lost.
Ignoring the 0.5% floor in 2026: over-claiming the disallowed first slice triggers an IRS adjustment.
Forgetting carryforwards: unused excess deductions expire after five years if you do not track them.
Confusing DAF limits with private-foundation limits: assuming the 20%/30% foundation caps apply costs you deduction room a DAF does not impose.
Donating depreciated assets in kind: if an asset is worth less than you paid, sell it, take the capital loss, and donate the cash instead.

Do’s and Don’ts

Do donate long-term appreciated stock to dodge capital-gains tax and deduct full market value — it is the most tax-efficient gift.
Do bunch multiple years of giving into one DAF contribution in 2026 to absorb the 0.5% floor only once.
Do keep every acknowledgment letter and appraisal, because the IRS denies deductions on missing paperwork.
Do track your five-year carryforward so no excess deduction expires unused.
Do time large gifts to high-income years to maximize the value of the deduction.
Don’t expect cash to take goods or services back from the DAF — the gift is irrevocable.
Don’t donate assets held one year or less expecting a full market-value deduction.
Don’t assume your state follows the federal rules — conformity varies widely.
Don’t ignore the 35% cap if you are in the 37% bracket in 2026.
Don’t file noncash gifts over $5,000 without the required appraisal.

Pros and Cons of Using a DAF

Pro — Immediate deduction, flexible giving: you deduct now and grant later, separating tax timing from charitable timing.
Pro — Capital-gains avoidance: appreciated assets transfer without triggering capital-gains tax, stretching your gift further.
Pro — Most generous AGI limits: DAF gifts get the 60%/30% public-charity caps, not the harsher foundation caps.
Pro — Simplified recordkeeping: one DAF receipt replaces dozens of individual charity receipts.
Pro — Built-in bunching tool: a DAF is the natural vehicle for clearing the standard deduction and 0.5% floor in one year.
Con — Irrevocable: once funded, you cannot reclaim the money for personal use.
Con — No payout requirement pressure for charities: money can sit undistributed, drawing criticism that funds are not reaching working charities.
Con — Fees: sponsors charge administrative and investment fees that reduce the amount available to grant.
Con — No personal benefit allowed: you cannot use DAF funds for anything with private value, like event tickets.
Con — 2026 rules reduce the benefit: the 0.5% floor and 35% cap shrink the federal tax savings versus prior years.

Federal vs. State Treatment

Federal law sets the AGI percentage caps, the 0.5% floor, and the 35% value cap. States are a separate question entirely. Some states with an income tax fully follow federal charitable-deduction rules, some impose their own caps or credits, and the nine states with no broad income tax — including Florida, Texas, and Washington — offer no charitable income-tax deduction because there is no income tax to reduce. The consequence of assuming your state mirrors the federal rules is a miscalculated state return. What you should do: check your state’s department of revenue page for charitable-deduction conformity before you file, since many states have not adopted the new federal 0.5% floor and may let you deduct more at the state level.

Federal Rule Comparison: 2025 vs. 2026

Rule	2025 vs. 2026
Cash deduction cap	60% of AGI in both years
Appreciated-asset cap	30% of AGI in both years
0.5% AGI floor	None in 2025; applies in 2026
35% value cap (37% bracket)	None in 2025; applies in 2026
Carryforward	Five years in both

What to Do Next

Decide what to give — long-term appreciated stock usually beats cash for the tax win.
Confirm your holding period is over one year and your asset has gained value.
Estimate your AGI and apply the right cap (60% cash, 30% appreciated), then subtract the 0.5% floor if giving in 2026.
Open or fund your DAF before December 31 to claim the deduction for that tax year.
Gather your acknowledgment letter, and for noncash gifts over $5,000, order a qualified appraisal.
File Schedule A for cash and Form 8283 for noncash gifts over $500.
Call a CPA or tax attorney if you are donating private business interests, real estate, crypto, or amounts large enough to trigger multi-year carryforwards — these situations carry real audit risk and benefit from professional review.

FAQs

What is the AGI limit for a cash donation to a donor-advised fund? 60% of AGI for tax years 2025 and 2026. Cash given to a DAF is deductible up to 60% of your adjusted gross income, with any excess carried forward for up to five years.

What is the AGI limit for donating stock to a DAF? 30% of AGI for long-term appreciated securities in 2025 and 2026. You deduct the full fair market value and avoid capital-gains tax, with excess carried forward five years.

Does the new 0.5% AGI floor apply to DAF gifts? Yes. Starting in tax year 2026, itemizers can deduct charitable gifts, including DAF gifts, only to the extent they exceed 0.5% of AGI. The first half-percent is disallowed.

Can I carry forward a DAF deduction I can’t use this year? Yes. Excess contributions above your AGI cap carry forward for up to five tax years, keeping the original 60% or 30% character of the gift.

What is the 35% deduction cap? A value limit for top earners. Beginning in 2026, donors in the 37% bracket save only 35 cents per dollar deducted instead of 37 cents.

Are DAF gifts deductible if I don’t itemize? No. The percentage caps require itemizing. The 2026 above-the-line deduction of up to $1,000 single / $2,000 joint generally does not cover gifts to a DAF.

Do I need to file Form 8283 for a DAF gift? Only for noncash gifts over $500. Cash gifts use Schedule A. Noncash contributions exceeding $500 require Form 8283 attached to your return.

Do I need an appraisal to donate stock to a DAF? No for publicly traded securities, even above $5,000. Other noncash property over $5,000 generally requires a qualified appraisal to claim the deduction.

Can I take my money back from a DAF? No. A contribution to a donor-advised fund is irrevocable. You can recommend grants over time, but you cannot reclaim the funds for personal use.

Is short-term appreciated stock deductible at market value? No. Assets held one year or less are deductible only at your cost basis, not fair market value, which usually makes cash a better gift.

Why did so many donors give in 2025 instead of 2026? To avoid the new limits. Tax year 2025 had no 0.5% floor and no 35% cap, so accelerating gifts into 2025 preserved the full deduction value.

Does my state follow these federal DAF rules? It depends on your state. Many states have not adopted the 2026 federal 0.5% floor, and no-income-tax states offer no charitable deduction at all. Check your state revenue agency.
