If you volunteer for a qualified charity, the IRS lets you deduct unreimbursed out-of-pocket costs tied to that work — mileage, supplies, uniforms, and travel — as a charitable contribution. The value of your time is never deductible, no matter what your hourly rate would be. And IRS deductions for volunteer work only help you if you itemize on Schedule A, meaning your total itemized deductions have to beat the standard deduction for your filing status ($16,100 single, $32,200 married filing jointly, $24,150 head of household in 2026).1Internal Revenue Service.

The Charity Has to Be Qualified
Your expenses only count when the organization is one the IRS recognizes. Most qualifying groups are 501(c)(3) nonprofits: religious congregations, schools, hospitals, scientific research organizations, and literary or educational charities.2Internal Revenue Service. Exempt Organization Types Federal, state, and local governments also qualify, so volunteering at a public school or a government-run program counts even without a separate IRS determination letter.3Internal Revenue Service. Tax Tips You Should Know if You Have Charity-Related Travel Expenses
Contributions to individuals, political campaigns, or candidates never qualify. Before claiming anything, verify the organization’s status using the IRS Tax Exempt Organization Search at irs.gov. Churches and government entities don’t always appear there because they aren’t required to apply for recognition, but other nonprofits should.
What You Can Deduct
Every expense you claim has to be unreimbursed, directly connected to your volunteer duties, incurred only because of those duties, and not personal or family in nature.4Internal Revenue Service. Publication 526, Charitable Contributions – Section: Out-of-Pocket Expenses in Giving Services The charity doesn’t need to have asked you to pay the cost. What matters is that the expense came directly from the work you did.
Driving Your Own Car
Vehicle costs are the most common volunteer deduction. You have two ways to calculate them: track actual gas and oil used on charitable trips, or use the IRS standard rate of 14 cents per mile.5Internal Revenue Service. IRS Sets 2026 Business Standard Mileage Rate at 72.5 Cents Per Mile, Up 2.5 Cents That 14-cent figure is set by statute and hasn’t moved in decades, unlike the business rate (72.5 cents in 2026) that the IRS updates each year. Because 14 cents barely covers fuel, tracking actual gas and oil often produces a larger deduction, especially on longer trips. If you use the standard rate, you cannot also deduct insurance, maintenance, or depreciation.
Either way, tolls and parking fees are deductible on top of the mileage calculation. Keep a contemporaneous log: date, destination, miles driven, and purpose of each trip, written down at or near the time of the trip. A log reconstructed at tax time is exactly what auditors challenge.
Supplies, Uniforms, and Small Costs
You can deduct materials you buy specifically for the charity’s work — groceries for a soup kitchen, lumber for a Habitat for Humanity build, printer paper for a nonprofit mailing. The items have to be consumed by the charity’s mission, not something you also use personally.
Uniforms and special clothing are deductible only if they aren’t suitable for everyday wear. A hospital volunteer vest or a scout leader uniform qualifies. A blazer you bought for board meetings does not, because you could wear it anywhere else.
Phone calls, postage, and other small administrative costs you pay out of pocket for the charity qualify too. Save every receipt.
Travel and Lodging
When volunteer work takes you away from home overnight, transportation, lodging, and meals are all deductible. This comes up with disaster relief, mission trips, and conventions for qualified charities.3Internal Revenue Service. Tax Tips You Should Know if You Have Charity-Related Travel Expenses Transportation covers airfare, train and bus tickets, rental cars, and taxi fares between stations and your lodging.
The IRS applies a strict rule here: there can be no significant element of personal pleasure, recreation, or vacation in the trip.6Office of the Law Revision Counsel. 26 U.S. Code 170 – Charitable, Etc., Contributions and Gifts Your duties have to be real and substantial throughout. Tagging along on a group resort trip and doing a few token hours of service won’t survive scrutiny. If your role is nominal or you spend chunks of the trip on personal activities, the IRS will disallow the whole deduction.
On a trip that mixes volunteer days with personal days, only the lodging and meals for the actual work days are deductible. Transportation to and from the destination can still be fully deductible if the primary purpose was volunteering, but sightseeing and recreation costs never are.
Hosting a Foreign Exchange Student
If you host a foreign exchange student through a qualified organization, you can deduct up to $50 per month for the time the student lives with you.7United States Department of State. Commonly Asked Questions The student has to be enrolled full-time in high school (through 12th grade) and can’t be a relative or dependent. The sponsoring organization must be a qualifying 501(c)(3) that runs or partners on a State Department–approved program. The $50 is a flat monthly amount, so you don’t have to track actual grocery or utility costs. Any month the student is with you for fewer than 15 days doesn’t count.
What You Cannot Deduct
The biggest limit: the value of your time is never deductible.4Internal Revenue Service. Publication 526, Charitable Contributions – Section: Out-of-Pocket Expenses in Giving Services An attorney who bills $400 an hour and donates 20 hours of legal work to a charity gets no deduction for the $8,000 in foregone billings. Lost wages from taking unpaid time off to volunteer aren’t deductible either.3Internal Revenue Service. Tax Tips You Should Know if You Have Charity-Related Travel Expenses
Personal expenses that happen to overlap with volunteer work are also out. Dry cleaning a suit you also wear to the office, buying a meal on your way home from volunteering, or paying for childcare so you can volunteer are all nondeductible, because they aren’t incurred solely because of the charitable work.
You also cannot deduct travel, meals, or lodging for a spouse or children who come along, even if they help out informally.8Internal Revenue Service. Publication 526, Charitable Contributions Each family member would need to be performing genuine volunteer services independently for their own costs to count.
Lobbying expenses and any political campaign activity are off limits too, even when the organization is otherwise a qualified charity.
Records You Need to Keep
The IRS can disallow any deduction you can’t document. For every cost, keep a receipt showing the amount, date, and purpose. Vehicle logs need date, destination, miles, and charitable purpose for each trip, written down at the time.
A separate rule applies to any single contribution of $250 or more: you must get a written acknowledgment from the charity before you file. Unreimbursed volunteer expenses count toward this threshold, so if you spent $300 out of pocket on supplies for one project, you need that letter. It has to state the amount of your cash contribution or describe any property contributed, and note whether the organization gave you anything in return (and if so, a good-faith estimate of its value). Without the acknowledgment, the deduction is gone regardless of how good your own records are. For expenses under $250, your receipts, bank statements, and mileage logs are enough on their own.
Claiming It on Your Return
Volunteer expenses go on Schedule A (Form 1040) as part of your total charitable contributions, combined with any cash or property donations you made during the year.9Internal Revenue Service. 2025 Instructions for Schedule A (Form 1040) – Itemized Deductions The practical barrier is that itemizing only pays off when your total itemized deductions — state and local taxes, mortgage interest, medical expenses, and charitable contributions combined — exceed your standard deduction.
For a married couple already close to $32,200 from mortgage interest and property taxes, a few thousand dollars in volunteer costs and other giving can tip them over. For a single renter with no mortgage interest, the math rarely works. Run it both ways before assuming the deduction helps you; tax software or a preparer can show the comparison quickly.
