You can deduct mileage for volunteer work at 14 cents per mile when you drive your own vehicle for a qualified charity, provided you itemize deductions on Schedule A. For tax year 2026, a new rule adds a second hurdle: your total charitable contributions must exceed 0.5% of your adjusted gross income before any of them count.
The 14-Cent Rate
The charitable mileage rate is fixed by statute at 14 cents per mile under Section 170(i) of the Internal Revenue Code.1Office of the Law Revision Counsel. 26 USC 170 – Charitable, Etc., Contributions and Gifts Congress wrote the number directly into the law, so the IRS cannot adjust it for inflation the way it adjusts the business mileage rate each year. It has been 14 cents since the late 1990s, and it remains 14 cents for 2026.2Internal Revenue Service. Standard Mileage Rates
A volunteer who drives 1,000 miles for a food bank over the year gets a $140 deduction. Drive 2,000 miles and it’s $280. The math is simple, and it’s also modest.
Which Organizations Qualify
Your driving has to be for an organization eligible to receive tax-deductible contributions under Section 170(c). That covers groups organized for religious, charitable, educational, scientific, or literary purposes, and certain government entities when the contribution serves a public purpose.1Office of the Law Revision Counsel. 26 USC 170 – Charitable, Etc., Contributions and Gifts In everyday terms, that means 501(c)(3) nonprofits, churches and other religious institutions, and units of federal, state, or local government.
Helping a neighbor move, volunteering at a for-profit company’s event, and running errands for a political campaign do not qualify, no matter how charitable the work feels. If you’re unsure, look the organization up in the IRS Tax Exempt Organization Search.3Internal Revenue Service. Tax Exempt Organization Search Churches and government entities often don’t appear in that database but still count.
Two Ways to Calculate the Deduction
You have a choice. Either multiply your charity-related miles by 14 cents, or track and deduct the actual cost of gas and oil consumed on those specific trips.4Internal Revenue Service. Publication 526, Charitable Contributions You can’t switch methods midyear for the same vehicle. The actual-cost approach rarely beats the standard rate unless your vehicle is a fuel hog, and you still have to log the miles either way.
Under either method, parking fees and tolls paid on volunteer trips are deductible on top of the mileage or gas-and-oil figure.4Internal Revenue Service. Publication 526, Charitable Contributions
Overnight Travel, Meals, and Lodging
When volunteer work takes you away from home overnight, reasonable meals and lodging are deductible as long as the expenses are directly tied to your service.5Internal Revenue Service. Tax Tips You Should Know If You Have Charity-Related Travel Expenses If a local Habitat for Humanity chapter sends you to a week-long build in another city, the hotel and out-of-pocket meals qualify.
The catch is written into the statute: the deduction is denied entirely if the trip involves a “significant element of personal pleasure, recreation, or vacation.”1Office of the Law Revision Counsel. 26 USC 170 – Charitable, Etc., Contributions and Gifts Enjoying the work doesn’t disqualify you, but your volunteer duties have to be genuine and substantial throughout. Three days at a build site followed by four days at the beach will sink the deduction, and if your duties are only token for large portions of the trip, the IRS can disallow the whole thing rather than just the personal part.4Internal Revenue Service. Publication 526, Charitable Contributions
Conventions follow the same logic. If a qualified charity picks you as its delegate, unreimbursed travel, meals, and lodging are deductible. Attending as an ordinary member is not, though costs directly tied to services you perform for the organization at the event still count.4Internal Revenue Service. Publication 526, Charitable Contributions
What You Cannot Deduct
The exclusions catch more people than the eligibility rules. None of the following are deductible:
- The value of your time or the income you give up to volunteer, no matter how skilled the work.
- General vehicle costs like depreciation, insurance, registration, tires, and routine maintenance and repairs. You get gas and oil (or the standard rate), and that’s it.4Internal Revenue Service. Publication 526, Charitable Contributions
- Traffic tickets and parking fines picked up on the way to a volunteer shift.6Internal Revenue Service. Publication 463, Travel, Gift, and Car Expenses
- Any expense the charity reimburses. Only unreimbursed amounts qualify.4Internal Revenue Service. Publication 526, Charitable Contributions
- Sightseeing, entertainment, unrelated meals, and expenses for a spouse or children who come along.
The exclusion of vehicle overhead is the one that stings. Your car wears down, your insurance covers those miles, and your tires lose tread — none of it counts. The deduction is designed to cover the marginal cost of fuel, not the full cost of operating a vehicle.
What Records to Keep
The IRS expects contemporaneous records, not a spreadsheet reconstructed the night before you file. Log each trip with four details: the date, where you drove, the number of miles, and the charitable purpose. If you use the actual-cost method, keep gas and oil receipts tied to volunteer trips.4Internal Revenue Service. Publication 526, Charitable Contributions Save receipts for parking and tolls too. A mileage app on your phone is fine as long as the records are detailed enough to back up what’s on your return.
If your total out-of-pocket charitable contributions for the year reach $250 or more, you also need a written acknowledgment from the organization. It has to state whether the charity gave you anything of value in return, and you need it in hand by the date you file your return.7Internal Revenue Service. Substantiating Charitable Contributions Charities don’t send these automatically. You have to ask.
How to Claim It on Your Return
Volunteer mileage goes on Schedule A (Form 1040) as a charitable contribution.4Internal Revenue Service. Publication 526, Charitable Contributions That means you have to itemize. Taking the standard deduction cancels the benefit entirely.
For 2026, the standard deduction is $16,100 for single filers, $32,200 for married couples filing jointly, and $24,150 for heads of household.8Internal Revenue Service. IRS Releases Tax Inflation Adjustments for Tax Year 2026 Mileage alone almost never gets you past those thresholds. Itemizing usually makes sense only when volunteer expenses combine with mortgage interest, state and local taxes, medical costs, and other charitable contributions. Add everything up before deciding.
The New 0.5% AGI Floor for 2026
The One, Big, Beautiful Bill Act added a floor that takes effect for tax years beginning after December 31, 2025. Starting in 2026, your charitable deduction is allowed only to the extent your total charitable contributions exceed 0.5% of your adjusted gross income.1Office of the Law Revision Counsel. 26 USC 170 – Charitable, Etc., Contributions and Gifts This is permanent and applies to all itemizers.
On an $80,000 AGI, the floor is $400. Your first $400 of giving produces no deduction. A volunteer who drives 2,000 miles and donates nothing else has $280 of mileage — well below $400, and worth zero on the return.
The floor looks at aggregate contributions, so cash gifts, donated property, and volunteer expenses all count toward clearing it. Add $1,000 in cash gifts to the same church, and your combined total is $1,280. Subtract the $400 floor and $880 is deductible. Mileage still helps, but it needs company.
