Donation Tax Deduction Calculator

Free calculator to estimate how much you can write off for charitable donations in 2025 and 2026. Compare your standard deduction against itemized deductions — including cash gifts to 501(c)(3) charities, non-cash donations valued at fair market value, SALT, mortgage interest, and medical expenses — to see whether itemizing beats the standard deduction and how much you'll save on your taxes.

Other itemized deductions

Keep it simple with the big ones.

Capped at $10,000 (federal).

Optional: medical expenses

Used for the 7.5% medical threshold and the cash donation limit estimate.

Only the amount above 7.5% of AGI is deductible.

How the donation tax deduction works

When you give to a qualified 501(c)(3) charity, the IRS lets you subtract the donation from your taxable income — but only if you itemize deductions on Schedule A instead of taking the standard deduction. For most taxpayers, itemizing only saves money when your total deductions (donations + state and local taxes + mortgage interest + qualifying medical) exceed the standard deduction.

The actual tax you save depends on your marginal tax bracket. A $1,000 donation saves a 24% bracket filer about $240, a 32% bracket filer $320, and so on. The calculator above does this math for you and flags the "aha" moment when itemizing starts beating the standard deduction.

How much can you write off for donations?

The IRS caps charitable deductions as a percentage of your adjusted gross income (AGI). For tax years 2024 and 2025, the most common limits are:

  • Cash to public charities: up to 60% of AGI
  • Non-cash goods (clothing, furniture, household items): up to 50% of AGI at fair market value
  • Long-term appreciated assets (stock, crypto, real estate): up to 30% of AGI
  • Contributions to certain private foundations: up to 20%–30% of AGI

Donations above the cap can typically be carried forward up to five years. Enable the carryforward toggle in the calculator to see how much excess could roll over.

2025 & 2024 standard deduction

Itemizing your donations only pays off when total itemized deductions exceed the standard deduction for your filing status.

Filing status 2025 2024
Single $15,000 $14,600
Married filing jointly $30,000 $29,200
Married filing separately $15,000 $14,600
Head of household $22,500 $21,900

Bunching tip: if your donations and other deductions are close to but below the standard deduction, consider concentrating two years of giving into a single tax year so you clear the threshold and itemize, then take the standard deduction next year.

Documentation & Form 8283

The IRS requires different records based on the value of your donations:

  • Under $250: bank record, credit card statement, or receipt from the charity
  • $250–$500: contemporaneous written acknowledgment from the charity
  • Over $500 in non-cash donations: attach Form 8283, Section A
  • Single non-cash item or similar group over $5,000: qualified appraisal and Form 8283 Section B

The Deductible.me app tracks every donation with photos, dates, FMV, and charity details — and generates IRS-ready Form 8283 reports automatically.

Frequently asked questions

How much can you write off for charitable donations?

For most taxpayers, cash donations to qualified 501(c)(3) charities are deductible up to 60% of AGI. Non-cash donations are generally capped at 50% of AGI, and donations of appreciated long-term assets are capped at 30%. Excess can usually be carried forward five years.

Can I deduct donations if I take the standard deduction?

No. For 2024 and 2025 you must itemize on Schedule A. The above-the-line $300/$600 donation deduction from 2020–2021 has expired.

What is the standard deduction for 2025?

$15,000 for single and married filing separately, $30,000 for married filing jointly, and $22,500 for head of household.

Do I need Form 8283 for donated items?

Yes — Form 8283 is required when your total non-cash donations for the year exceed $500. Items worth more than $5,000 generally also require a qualified appraisal.

How do I value donated clothing, furniture, or household goods?

Use fair market value — what a willing buyer would pay at a thrift store or on a resale marketplace. See the Donation Value Guide for typical price ranges by item and category, and a free FMV calculator.
