Not tax advice. This page summarizes general IRS rules for U.S. organizations and links to the sources. Rules change and situations vary. Your treasurer, your district or a tax professional should confirm how they apply to your organization and your donors.
Quick answer. Donations to a 501(c)(3) walk-a-thon organizer are generally deductible for donors who can claim charitable deductions, in the year they're paid. Send a written acknowledgment for any single gift of $250 or more, and a disclosure when a donor gives over $75 and gets something back. Only say gifts are tax deductible if your organization actually qualifies.
Step 1: know your organization's status
| Who's running the walk | Are gifts generally deductible? | What to check |
|---|---|---|
| PTA, PTO or booster club with 501(c)(3) status | Yes, for qualifying donors | Your status in the IRS Tax Exempt Organization Search4 |
| Parent group without 501(c)(3) status | Generally no | Whether you fundraise under a qualifying parent organization |
| Public school or district | Often yes; contributions to government units for public purposes can qualify | Ask the district business office how gifts should be made and receipted |
| Church or charity | Generally yes, for qualifying donors | Your treasurer's standard receipting process |
| Gift to an individual (e.g. one family) | No | Don't describe personal fundraising as deductible |
Whether a particular donor benefits also depends on their own tax situation, so say “may be tax deductible to the extent allowed by law” rather than promising a deduction.
A few school types have their own wrinkles. Catholic parish schools covered by a group exemption may not appear by name in the IRS search (see the Catholic school walk-a-thon guide); charter schools need to decide which entity receives the money (see the charter school guide); and not every homeschool co-op is a 501(c)(3) organization (see the homeschool walk-a-thon guide).
Step 2: understand pledges and timing
A pledge isn't a contribution until it's paid. The IRS treats a pledge as deductible in the year the donor pays it, and only for the amount actually paid.2,3 For a walk-a-thon that means:
- A flat donation paid online counts on the date it's paid.
- A per-lap pledge counts when the donor pays the final total after the walk, for the amount they paid (laps × rate, up to any cap). The pledge calculator works out that total.
- Walks in late November or December can push per-lap payments into January, and so into the next tax year. Mention it in your collection message if your walk is late in the year.
Step 3: send the right acknowledgments
Gifts of $250 or more: written acknowledgment
A donor can't deduct any single contribution of $250 or more without a contemporaneous written acknowledgment from the organization. It should include the organization's name, the amount, and a statement of whether the organization provided any goods or services in return (and, if so, a good-faith estimate of their value).1 Check whether your online donation tool's receipt comes from your organization and includes the amount and the goods-or-services statement; if not, send your own. For checks and cash, your treasurer sends it.
Over $75 with something in return: disclosure
If a donor pays more than $75 and receives goods or services in return, such as a dinner ticket or a premium item, the organization must give a written statement explaining that only the amount above the value of what they received is deductible, with a good-faith estimate of that value.1 Token items of small value can be exempt; IRS Publication 1771 explains the thresholds. A shirt handed to a student walker who paid nothing isn't a donor benefit, but ask your treasurer about anything else.
Registration fees are different
At walks with a registration fee (common at charity and community walks), the person paying usually gets something back: a shirt, a medal, food. That makes the fee a quid pro quo payment. Only the amount above the fair market value of what they received is deductible, and if the fee is more than $75 you must give the written disclosure described above.1 Extra fundraising beyond the fee, with nothing more received in return, is treated as a regular contribution. See the charity walk-a-thon guide for fee models.
Sample acknowledgment wording
“Thank you for your gift of $[amount] on [date] to [Organization], a 501(c)(3) organization (EIN [number]), in support of our [Event Name]. No goods or services were provided in exchange for this contribution.”
A version you can personalize is in the letter and message templates. Adjust the last sentence if donors received something of value. Public school districts use their own acknowledgment wording (no EIN or 501(c)(3) line needed); ask the district business office.
Matching gifts: an easy way to raise more
Many employers match employees' donations to eligible schools and nonprofits. Matches are usually requested by the donor through their employer, and eligibility rules vary by company. Include one line about matching gifts in your kickoff letter and receipt (“Ask your employer whether it matches gifts to [Organization]”), and keep your EIN and mailing address handy for verification requests. More tactics are in walk-a-thon fundraising ideas.
Business sponsors are different
Sponsorship payments from businesses follow their own IRS rules on acknowledgment versus advertising. See the walk-a-thon sponsorship guide.
Record keeping for organizers
- Keep a donation log with donor name, amount, date paid, method, and receipt sent.
- Reconcile online, cash and check totals against your log before announcing the final number. See handling cash and checks.
- Keep pledge sheets and lap records until collection closes and your books are reviewed.
- Hand the log to next year's treasurer as part of the PTA/PTO handoff.

Frequently asked questions
Are walk-a-thon donations tax deductible?
Often, but not always. Gifts to a 501(c)(3) organization, such as a PTA or PTO with that status, a church or a charity, are generally deductible for donors who qualify to claim charitable deductions. Gifts to a group without 501(c)(3) status, or money given directly to an individual, are not. Donors should check current IRS rules or a tax professional for their own situation.
Is a per-lap pledge deductible when it's made or when it's paid?
When it's paid. Under IRS rules a pledge is deductible in the year the donor actually pays it, and only the amount paid counts. A per-lap pledge made in December but paid in January belongs to January's tax year.
Do walk-a-thon organizers have to send donation receipts?
For any single gift of $250 or more, the donor needs a written acknowledgment from the organization to claim the deduction. If a donor pays more than $75 and receives goods or services in return, the organization must give a written disclosure of their value. Many groups send a thank-you receipt for every gift because it's good practice and builds next year's donor list.
Our PTO isn't a 501(c)(3). Can donors still deduct their gifts?
Generally no, unless the money goes to a qualifying organization. Some parent groups fundraise under a 501(c)(3) parent organization or for a public school district. Check your status in the IRS Tax Exempt Organization Search and be accurate in your messages: don't call gifts tax deductible unless they are.
