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.
