Charitable Donation Calculator: Give by December 31, 2026 to Claim the New $1,000 Deduction

Starting with tax year 2026, you can deduct up to $1,000 of cash donations to qualified charities even if you take the standard deduction. If you file a joint return, the limit is $2,000. The donations must be paid by December 31, 2026 to count for 2026. Use the calculator below to see how much room you have left under the limit and what the deduction could be worth to you.

The give-by-December-31 calculator

Donations count for 2026 only if they are paid by December 31, 2026.

Which best describes you?

Cash, check, card, transfer, or payroll deduction to a qualified organization only. Leave out property, donor-advised funds, and gifts to individuals.

What this deduction is

Before 2026, charitable donations generally only reduced your tax if you itemized deductions on Schedule A (Form 1040). Most filers take the standard deduction instead, so their donations produced no federal tax benefit.

Public Law 119-21, the law enacted on July 4, 2025 and often called the One Big Beautiful Bill Act, changed that for tax year 2026. The IRS states the new rule in Topic No. 506, Charitable Contributions: “Beginning with tax year 2026, if you do not itemize, you may deduct up to $1,000 ($2,000 if filing jointly) of your cash contributions to certain qualified organizations.”

Three points decide whether a donation counts:

  1. It must be cash. In IRS usage, cash contributions include money paid by cash, check, credit card, debit card, electronic transfer, or payroll deduction. Donations of clothing, household goods, stock, or other property do not count toward this $1,000 or $2,000 deduction. Property donations follow the separate itemized rules in IRS Publication 526.
  2. It must go to a qualified organization. Gifts to individuals are not deductible, no matter how worthy the cause. You can check an organization before you give with the IRS Tax Exempt Organization Search tool at irs.gov.
  3. It must be paid in 2026. A pledge is not a payment. The calculator above works on amounts you have already paid in 2026 plus amounts you still plan to pay by December 31, 2026.

The limits, in one table

Maximum deduction for cash donations if you do not itemize, tax year 2026
Your 2026 filing statusMaximum deduction
Single$1,000
Head of household$1,000
Married filing jointly$2,000

Source: IRS Topic No. 506 states the $1,000 limit and the $2,000 joint limit. One filing status is not shown: the limit for married filing separately has not been confirmed in the final 2026 Form 1040 instructions, which are still a draft, so this page does not state a figure for it yet.

The draft 2026 Form 1040, posted by the IRS on September 17, 2026 and still a draft when this page was reviewed, shows this deduction on its own line alongside the standard deduction. That placement means the deduction reduces taxable income. On the draft form it does not reduce adjusted gross income. Final line placement and wording will be confirmed when the IRS publishes the final 2026 Form 1040 and its instructions.

There is no carryforward for this deduction. If you give $400 of qualifying cash in 2026, the deduction is $400. If you give $3,000 as a single filer, the deduction is still $1,000. Amounts above the limit do not roll into 2027 under this rule.

What the deduction is worth

This is a deduction, not a credit. A $1,000 deduction does not cut your tax by $1,000. It cuts the income your tax is calculated on by $1,000, so the saving depends on your marginal tax bracket.

Approximate federal saving by marginal bracket
If your marginal federal bracket isA $1,000 deduction saves aboutA $2,000 deduction saves about
10 percent$100$200
12 percent$120$240
22 percent$220$440
24 percent$240$480
32 percent$320$640
35 percent$350$700
37 percent$370$740

These are simplified estimates. If the deduction moves part of your income into a lower bracket, or if your taxable income is smaller than the deduction, the actual saving is lower. The calculator handles the bracket method for single and joint filers using the tax year 2026 rate thresholds in IRS Revenue Procedure 2025-32, announced in IRS release IR-2025-103 on October 9, 2025. For other filing statuses, the calculator asks you to select your bracket instead of guessing it.

For context, the 2026 standard deduction itself is $16,100 for single filers and married filers filing separately, $32,200 for married couples filing jointly, and $24,150 for heads of household (Revenue Procedure 2025-32). You claim the standard deduction and this charitable deduction. You do not have to choose between them.

Donations that do not count toward this deduction

When in doubt, check the organization in the IRS Tax Exempt Organization Search tool before you pay, not after December 31.

If you itemize instead: the new 0.5 percent floor

Itemizers follow different math in 2026, and it also changed. Under Public Law 119-21, an itemizer can deduct charitable contributions only to the extent that total contributions exceed 0.5 percent of adjusted gross income. The first slice produces no deduction.

The itemizer floor at four income levels
If your 2026 adjusted gross income isThe first amount of giving that produces no itemized charitable deduction is
$50,000$250
$100,000$500
$200,000$1,000
$400,000$2,000

The calculator includes an itemizer mode that applies this floor as an estimate and compares the result with the standard deduction amounts above. Whether itemizing beats the standard deduction depends on all of your itemized deductions together, not charity alone. This page estimates the charitable piece only.

The long-standing limit that cash contributions to public charities are generally deductible up to 60 percent of adjusted gross income for itemizers continues, and Publication 526 carries the full percentage limits and carryover rules.

Questions and answers

Do I have to itemize to get the $1,000 charitable deduction in 2026?

No. That is the point of the new rule. Beginning with tax year 2026, the IRS states that if you do not itemize, you may deduct up to $1,000 of cash contributions to certain qualified organizations, or $2,000 if you file jointly.

Does a donation of clothes or household goods count toward the $1,000?

No. The new deduction covers cash contributions only. Property donations are covered by the separate itemized rules in Publication 526 and do not count toward this limit.

I already gave $600 this year. How much more can I deduct if I give by December 31?

As a single filer, $400 more of qualifying cash donations would bring you to the $1,000 limit. On a joint return, $1,400 more would bring you to the $2,000 limit. The calculator above works this out from your own figures, including gifts you have already paid.

Is the $1,000 a credit that cuts my tax by $1,000?

No. It is a deduction. It reduces taxable income, so the saving is the deduction multiplied by your marginal rate. At a 22 percent bracket, a $1,000 deduction saves about $220.

Can I carry unused room or extra giving into 2027?

No. There is no carryforward under this non-itemizer rule. Qualifying cash given in 2026 counts for 2026, up to the limit, and that is the end of it.

What if I give to a donor-advised fund?

Contributions to a donor-advised fund do not qualify for this deduction, based on summaries of Public Law 119-21. Give directly to a qualified operating charity if you want a donation to count toward the $1,000 or $2,000 limit, and verify the organization in the IRS Tax Exempt Organization Search tool.
