Volunteer Mileage Reimbursement for Nonprofits
Volunteer time cannot be deducted — but the miles driven in service of a charity can be.
Many volunteers do not track that mileage, which means they either leave a tax benefit
unclaimed or miss out on direct reimbursement their organization is ready to provide. The
barrier is almost always documentation, not eligibility.
Charities use mileage logs to reduce the financial cost of volunteering in two ways: through
the IRS charitable mileage deduction on a volunteer's own tax return, or through a direct
tax-free reimbursement under an accountable plan. Both require the same accurate, timely
records — and MileHawk provides exactly that, for free, on any phone.
Method one: the charitable mileage tax deduction
Volunteers who itemize their federal taxes can deduct 14 cents per mile driven in service
of a qualifying 501(c)(3) organization. The rate is set by statute and covers driving to
and from the volunteer site, delivering goods for the charity, transporting clients, and
similar service-related travel. Parking fees and tolls are always deductible as a
separate out-of-pocket expense on top of the mileage rate.
As an alternative to the standard rate, volunteers may deduct actual fuel costs — but
this requires documenting the amount of fuel used and the cost per gallon in addition to
the standard trip log. Overhead costs such as depreciation, maintenance, repairs, and
registration fees are not deductible under either method.
To claim the deduction, the volunteer needs a contemporaneous log showing dates,
destinations, the charitable purpose of each trip, and miles driven. For any single
unreimbursed contribution of $250 or more, the organization must provide a written
acknowledgment stating the service performed, the date, and confirming that no goods or
services were received in exchange. The volunteer must have this acknowledgment in hand
by the time they file. Without it, the deduction is disallowed regardless of how good
the mileage log is.
One significant limitation: this approach only benefits volunteers who itemize on
Schedule A. For the majority of filers who take the standard deduction, the charitable
mileage deduction produces no tax benefit — which is one reason direct reimbursement is
often more practical.
Method two: accountable plan reimbursements
Many nonprofits prefer to reimburse volunteers directly rather than asking them to wait
for tax season. Under an IRS accountable plan, a charity can reimburse volunteers up to
14 cents per mile — the federally capped charitable rate — completely tax-free to the
volunteer. The volunteer receives a check or direct deposit shortly after submitting their
log, with no tax reporting required on either side.
Accountable plans are particularly valuable for lower-income volunteers or those affected
by high fuel costs. The ability to be made whole quickly — rather than waiting to see
whether itemizing pays off — removes a meaningful barrier to participation, especially for
volunteers who drive regularly for meal delivery, patient transport, or site visits.
For the plan to qualify, the organization must have a written policy requiring volunteers
to submit documentation within a reasonable period (the IRS guidance is 60 days), and the
documentation must include dates, destinations, service purpose, and mileage. MileHawk's
export meets all of these requirements out of the box.
What accurate logs mean for volunteer engagement
Organizations that actively help volunteers track and claim mileage — whether through
reimbursement or by walking them through the tax deduction process — consistently report
stronger volunteer retention. Covering the out-of-pocket cost of gas and wear-and-tear
makes it easier for more people to say yes to driving roles, including those who would
otherwise feel the cost is too high relative to the contribution.
Some corporate employers add another layer through Dollars for Doers programs: matching
grants paid directly to the nonprofit based on employee volunteer hours and, in some
programs, miles driven. Accurate mileage logs support these applications and help the
organization capture matching funds it might otherwise miss.
What volunteers cannot deduct
The IRS is clear that the value of a volunteer's time, skills, and expertise is never
deductible — even for professionals donating hundreds of dollars an hour of specialized
work. Only actual out-of-pocket expenses are in play, and not all of those qualify.
Specifically not deductible: childcare costs incurred so the volunteer can serve,
personal clothing purchased or cleaned for volunteer work (unless it is a required
uniform that cannot be worn in everyday life), and meals or snacks unless the work
requires an overnight stay away from home. The fair market rental value of personal
equipment or space provided to the charity is also not deductible, though consumable
supplies like paper and postage are.
For a comprehensive treatment of these rules, the IRS publishes detailed guidance in
Working with Volunteers
and Publication 526, Charitable Contributions.
Frequently asked questions
Can a volunteer deduct the value of their time or skills?
No. The IRS is explicit on this point: the value of a volunteer's time, skills, and expertise is not deductible as a charitable contribution — even if the volunteer is a professional donating services worth hundreds of dollars per hour. Only out-of-pocket expenses directly related to the volunteer work are potentially deductible, and only those that meet the specific IRS requirements for substantiation.
What personal expenses are NOT deductible for volunteers?
Several common volunteer-related costs are not deductible. A babysitter hired so the volunteer can serve the charity is not deductible. Clothing purchased or cleaned for volunteer service is not deductible unless it is a required uniform that cannot be worn in everyday life. Meals and snacks the volunteer buys for themselves are not deductible unless the work requires an overnight stay. The fair market value of personal equipment or space provided to the charity is also not deductible — though consumable supplies like paper are.
What is the IRS charitable mileage rate for volunteers?
The IRS sets a charitable mileage rate of 14 cents per mile for miles driven in service of a qualified 501(c)(3) organization. This rate is set by statute and does not adjust annually the way the business rate does. Volunteers can use this rate to calculate either a tax deduction on Schedule A or the amount to submit for reimbursement under an accountable plan.
What is the difference between a tax deduction and a reimbursement for volunteer mileage?
A tax deduction lets the volunteer claim the charitable mileage rate on their own federal return — but only if they itemize deductions on Schedule A, and only in the tax year the driving occurred. A reimbursement is a direct payment from the nonprofit to the volunteer, made shortly after the miles are driven, using an IRS-approved accountable plan. Reimbursements can be more accessible for volunteers who do not itemize or who need financial relief before tax season.
What is an accountable plan and how does a nonprofit set one up?
An IRS accountable plan is a formal reimbursement arrangement that meets three requirements: the expense must have a business (or in this case, charitable service) purpose, the employee or volunteer must substantiate the expense with documentation, and any excess reimbursement must be returned. Reimbursements made under a qualifying accountable plan are tax-free to the volunteer. A nonprofit establishes one by adopting a written policy that requires volunteers to submit logs with dates, destinations, mileage, and purpose within a reasonable time — typically 60 days.
What records does a volunteer need to submit for mileage reimbursement?
The IRS and most nonprofits require the same five data points for each trip: the date of the drive, the starting point and destination, the specific volunteer service performed, the miles driven, and the vehicle's odometer reading at the start and end of the trip or reporting period. A MileHawk export — PDF or CSV — includes all of these fields and can be submitted directly to the organization's reimbursement coordinator.
Does a volunteer need to itemize their taxes to use the charitable mileage deduction?
Yes. The charitable mileage deduction is claimed on Schedule A, which requires the taxpayer to itemize rather than take the standard deduction. For volunteers whose total itemized deductions do not exceed the standard deduction for their filing status, the tax deduction provides no benefit — which is one reason direct reimbursement through an accountable plan can be more practical for many volunteers.
What does a charity need to provide for a volunteer mileage donation over $250?
For any unreimbursed charitable contribution — including mileage — valued at $250 or more, the IRS requires a contemporaneous written acknowledgment from the organization. The letter must describe the services performed and state whether the volunteer received any goods or services in return. Volunteers claiming the deduction without this acknowledgment risk having the deduction disallowed.
Can a volunteer be reimbursed and still claim a tax deduction?
No. A volunteer can only deduct miles that were not reimbursed. If the organization reimburses at the full 14-cent IRS charitable rate, there is no deductible amount remaining. If the organization reimburses at a lower rate, the volunteer may deduct the difference — but only if they itemize. Double-claiming reimbursed miles as a deduction is not permitted.
What are "Dollars for Doers" programs and how does mileage logging apply?
Dollars for Doers (also called volunteer grants) are corporate programs where an employer donates a cash grant to a nonprofit on behalf of an employee who volunteers there. Some programs also consider volunteer driving as part of the qualifying contribution. Accurate mileage logs help volunteers document their service hours and miles when submitting grant applications through their employer, ensuring the nonprofit receives the maximum matching benefit.
Why do nonprofits care whether volunteers track mileage accurately?
Inaccurate mileage logs create risk for both the volunteer and the organization. Over-reported miles can trigger IRS scrutiny of the volunteer's return and raise questions about the nonprofit's recordkeeping. Under-reported miles mean volunteers leave money on the table that could offset their out-of-pocket costs. Accurate, contemporaneous logs — especially those with odometer readings — protect both parties and support the organization's compliance with IRS accountable plan requirements.
Can a volunteer deduct actual fuel costs instead of using the standard mileage rate?
Yes. Instead of the 14-cent standard rate, a volunteer can deduct the actual amount paid for fuel — but the recordkeeping is more involved. In addition to the standard trip log requirements, the volunteer must document the amount of fuel used and the cost per gallon. Either way, parking fees and tolls are always deductible as separate out-of-pocket expenses. Overhead costs such as depreciation, maintenance, repairs, and registration fees cannot be deducted under either method.
How long should volunteers and nonprofits keep mileage records?
The IRS recommends keeping records and supporting documentation for at least three years. This applies to both the volunteer's personal log and the nonprofit's reimbursement records. In the event of an audit, the organization should be prepared to show that any payment was genuinely a reimbursement, what expense it covered, when it occurred, and how it relates to the organization's mission.
