Your PTO’s bake sale might feel harmless.
Your silent auction might feel “too small” to matter.
But here’s the reality — the IRS doesn’t care if you’re a group of well-meaning parents selling brownies to fund playground swings.
If you break the rules, they will notice. And they will fine you. None of this requires bad intentions. It just requires nobody realizing a bake sale and a business both answer to the same tax code.
Fundraising ≠ Free-for-All
Even though PTOs are typically nonprofit organizations, the IRS still has rules about:
- How you earn money
- How you report it
- How you spend it
None of these three requirements are unique to big organizations. They apply just as fully to a PTO that raised four hundred dollars as one that raised forty thousand.
Ignoring those rules isn’t just risky — it’s expensive.
Three Ways PTOs Accidentally Cross the IRS
1. Forgetting to Report Fundraiser Income
Fundraising proceeds generally need to be properly recorded and reported, depending on the type of activity and the PTO’s tax status. Leaving it off your report can trigger penalties.
Example: One PTO didn’t think they needed to report a $4,000 carnival because “it all went back to the school.” The IRS saw it differently and slapped them with fines. Money going back to the school doesn’t automatically make the proceeds exempt from reporting.
2. Mixing “Nonprofit” and “Personal” Money
If funds from a fundraiser even briefly touch a personal account, it’s a red flag.
Example: A volunteer used her personal Venmo to collect payments for a spirit wear sale. She transferred the money later, but the IRS classified it as her income until she proved otherwise. A personal Venmo account feels convenient in the moment. It’s also the fastest way to turn a PTO’s fundraiser into someone’s personal tax problem.
3. Spending Outside the Mission
If PTO funds are spent on items unrelated to your group’s mission, the IRS can argue you’re no longer operating as a nonprofit. A single off-mission purchase rarely triggers scrutiny on its own. A pattern of them is exactly what an audit looks for.
What the IRS Expects
- Accurate Records: Dates, amounts, sources, and receipts for all income and expenses.
- Proper Filings: Annual Form 990 (or 990-EZ/990-N) depending on your revenue.
- Mission Alignment: Spending must support your PTO’s stated purpose.
None of these three expectations require an accounting degree to meet. They just require someone deciding to keep up with them consistently.
How to Stay Out of Trouble
- Track Every Fundraiser — No matter how small.
- Deposit Immediately — Into the PTO’s account, never personal accounts.
- Document Spending — Keep receipts, invoices, and board approval minutes.
- Get Professional Help — Especially for annual filings or unusual transactions.
None of these four habits are complicated individually. Skipping just one of them is usually how a PTO ends up explaining itself to the IRS.
True Story: A PTO raffled off an iPad without following their state’s raffle licensing rules. Not only did they have to return the money, but they also had to deal with the consequences of running an unlicensed raffle. Raffle rules vary by state, so check the requirements before you sell a single ticket.
Bottom line: The IRS doesn’t care if you’re a group of unpaid parents. They care about accurate reporting and compliance. The easiest way to keep the IRS happy — and your PTO safe — is to make professional accounting part of your yearly routine. The PTOs that never hear from the IRS aren’t the ones with the smallest fundraisers. They’re the ones who treated every dollar the same way, whether it came from a bake sale or a five-figure gala.
