Charitable deduction 2026: 0.5% floor, 35% cap and $1,000 rule

The 2026 charitable deduction has a 0.5% floor and a 35% cap for top earners. Non-itemizers can deduct up to $1,000, or $2,000 joint. Here is how each works.

The charitable deduction for 2026 comes with three new rules. If you itemize, the first 0.5% of your AGI in gifts is not deductible. In the 37% bracket, each deducted dollar now saves at most 35 cents.

If you do not itemize, you can now deduct up to $1,000 of cash gifts, or $2,000 on a joint return. All three rules began on January 1, 2026, with no end date. Gifts must be made by December 31, 2026 to count this year.

Law	Public Law 119-21, the One Big Beautiful Bill Act
Itemizers	Gifts count only above 0.5% of AGI
37% bracket	Each itemized dollar saves at most 35 cents
Non-itemizers	Up to $1,000 in cash, or $2,000 joint
Status on October 22, 2026	In effect, with no end date

What changed for the charitable deduction in 2026?

Four changes apply to 2026 gifts.

A 0.5% floor. Itemized gifts count only above 0.5% of AGI, so the first dollars you give each year earn nothing.
A cap in the 37% bracket. Itemized deductions are cut by 2/37, so each dollar saves at most 35 cents.
A deduction without itemizing. You can deduct up to $1,000 of cash gifts, or $2,000 joint, on top of the standard deduction.
The 60% cash limit stays. It was due to drop to 50% of AGI after 2025, and is now permanent.

What is the new 0.5% floor on charitable deductions in 2026?

It is a yearly threshold: only gifts above 0.5% of your AGI are deductible. A couple with $400,000 of AGI who give $10,000 can deduct $8,000.

The floor comes off what the AGI limits allow, and what it takes is usually lost. It carries forward only from a year in which your gifts also exceed an AGI limit.

How does the 35% cap affect donors in the 37% bracket?

It cuts what each itemized dollar saves from 37 cents to at most 35 cents. The law reduces your itemized deductions by 2/37 of the smaller of two amounts. One is those deductions. The other is your taxable income, plus those deductions, above the start of the 37% bracket.

For 2026, that bracket starts at $768,700 of taxable income on a joint return and $640,600 for single filers. The cut reaches every itemized deduction, not only gifts, and comes after the floor.

How do the floor and the cap stack for a top-bracket donor?

They stack: the floor comes off first, and the 2/37 cut applies to the rest. Take a married couple with $1,000,000 of AGI who already itemize and give $50,000 in cash. Their income stays deep in the 37% bracket.

Step	Amount
Lost to the 0.5% floor	$5,000
Left after the floor	$45,000
Cut by 2/37	$2,432
Tax saved at 37%	$15,750
Saved without the new rules	$18,500

The couple saves 31.5 cents per dollar given. The larger the gift is compared with AGI, the closer that gets to 35 cents.

Can you claim charitable donations without itemizing in 2026?

Yes: from 2026 you can deduct up to $1,000 of cash gifts to qualifying charities, or $2,000 joint. It comes off after AGI, next to the standard deduction, so it does not lower your AGI.

Neither the floor nor the 2/37 cut applies to it. Gifts to donor-advised funds and supporting organizations do not qualify, and neither do gifts of property or carryovers.

For 2026, the standard deduction is $16,100 for single filers and $32,200 on a joint return. Itemize only if your total beats that plus the cash gift deduction you would give up.

What are the AGI limits for cash and stock donations?

Cash to public charities counts up to 60% of AGI, and stock held over a year up to 30%.

Gift to a public charity	Limit
Cash	60% of AGI
Stock held one year or less, at cost	50% of AGI
Stock held over a year, at market value	30% of AGI

Most private foundations get lower limits: 30% for cash and 20% for long-held stock. Gifts above a limit carry forward for five years.

Should I bunch donations in 2026 or a later year?

Bunching still pays, but no later year has better rules to wait for. The chance to give before the floor and cap ended on December 31, 2025.

Bunch to itemize. Give two or three years of gifts in one year. In the other years, give up to $1,000, or $2,000 joint, in cash straight to charities.
Pay the floor less often. It applies in every year you give, so at a steady AGI, fewer and larger gift years lose less to it.
Use a donor-advised fund. You deduct the gift when you fund it and recommend grants later. See our donor-advised fund guide.
Give appreciated stock. Stock held over a year and given to a public charity is deducted at market value. You never pay tax on its gain.
Give in your highest-income year. A deducted dollar saves about 35 cents in both the 35% and 37% brackets, but less in a 32% year.

When do the new charitable rules apply?

Date	What happens
July 4, 2025	The law is signed
January 1, 2026	The three new rules begin
December 31, 2026	Last day for a 2026 gift
Before you file	Get receipts for gifts of $250 or more

A mailed check counts the day you mail it. Shares a broker moves for you count only once they reach the charity or fund.

What should you do now?

Compare your 2026 state and local taxes, mortgage interest and gifts with your standard deduction.
Above $505,000 of modified AGI, your SALT cap shrinks from $40,400 toward $10,000, which makes itemizing harder.
If you itemize in 2026, consider moving gifts planned for 2027 into a donor-advised fund now.
Start stock transfers in early December, and get a written receipt for each gift of $250 or more.
