Somewhere in your nonprofit’s first year, a board member says the magic words: “We’re a 501(c)(3), so we don’t pay taxes.” It feels true. It’s also only partly true — and the gap between “partly” and “fully” is exactly where small nonprofits get a surprise letter from the IRS or their state. If you’ve ever felt a flicker of doubt about which taxes your organization actually owes, you’re asking the right question: do nonprofits pay taxes, and if so, which ones?
Here’s the honest version: tax-exempt doesn’t mean tax-free. It means you’re exempt from federal income tax on the money you raise and spend on your mission — a big, valuable exemption. But several other taxes don’t disappear, and a few depend entirely on your state. Think of 501(c)(3) status like a student discount: it’s real and worth a lot, but it applies to specific things. Flash it at the wrong counter and you still pay full price.
Key Takeaways
Mostly no, but not never. A 501(c)(3) pays no federal income tax on money it raises and spends on its mission, which is the tax most people mean when they ask the question. But the same organization can still owe payroll taxes, tax on unrelated business income, and — depending on the state — sales and property tax. The table below is the honest map.
| Tax | Does a 501(c)(3) pay it? | What to know |
|---|---|---|
| Federal income tax (mission income) | No | The core exemption — income raised and spent on your exempt purpose. |
| Annual return (Form 990) | File, but no tax | An information return. You report; you generally owe nothing on mission income. |
| Tax on unrelated business income | Yes | UBIT. File Form 990-T if gross unrelated income is $1,000 or more. |
| Payroll: income withholding + FICA | Yes | Same as any employer with paid staff. |
| Federal unemployment tax (FUTA) | No | 501(c)(3)s are exempt; state unemployment rules still vary. |
| State income tax | Usually no | Often exempt, but typically requires a separate state application. |
| Sales tax (buying or selling) | Depends on state | Not automatic. Some states even require nonprofits to collect sales tax on sales. |
| Property tax | Often exempt | Varies by state and locality; may require an application. |
The headline exemption is federal income tax on income related to your exempt purpose. When your organization raises donations, grants, and program revenue and spends them advancing your mission, that activity is not subject to federal income tax — which is exactly what makes the nonprofit model work. In most states, a similar income tax exemption follows, though you usually have to apply for it separately at the state level.
That’s the part the board member got right. The trouble starts when “exempt from income tax” quietly becomes “exempt from all taxes” in everyone’s mind. Those are different statements, and the next few sections are the difference.
The myth
“We’re a 501(c)(3), so we don’t pay any taxes and don’t file anything.”
The reality
You’re exempt from income tax on mission income, but you still file Form 990, pay payroll taxes on staff, may owe UBIT, and follow your state’s sales and property tax rules.
Yes — almost every 501(c)(3) files an annual Form 990, even though it usually owes no tax. The 990 is an information return: it tells the IRS and the public how your organization raised and used its money, not how much tax you owe. Skipping it is one of the few ways a nonprofit can actually lose its exempt status, because three consecutive missed filings trigger automatic revocation.
Which version you file depends on your size — the postcard-style 990-N, the 990-EZ, or the full 990. We cover the differences in Form 990-EZ vs 990, the timing in the Form 990 deadline calendar, and the mechanics in our step-by-step filing guide. The IRS’s About Form 990 page is the primary source.
Yes. If your nonprofit has paid employees, it handles payroll taxes like any other employer: you withhold federal income tax and the employee’s share of Social Security and Medicare (FICA), and you pay the matching employer share. Tax-exempt status applies to income tax, not employment tax — this catches a lot of first-time nonprofit employers off guard.
There is one real break: 501(c)(3) organizations are exempt from federal unemployment tax (FUTA). State unemployment is a separate question, and the rules vary — some states let nonprofits reimburse benefits paid rather than pay the standard tax. Getting payroll set up correctly from the start is far cheaper than fixing it after a notice; it’s one of the items we flag in the first 90 days of nonprofit bookkeeping.
Not sure if your 990 or UBIT is handled correctly?
GivingArc prepares Form 990 and nonprofit tax filings so nothing slips — and your exempt status stays protected.
UBIT — unrelated business income tax — is the income tax a nonprofit owes on money it earns from activities that aren’t related to its exempt mission. If your organization regularly carries on a trade or business that isn’t substantially related to your purpose, the profit from it can be taxable, even though your mission income isn’t. When your gross unrelated business income reaches $1,000 or more in a year, you file Form 990-T and may owe tax at standard corporate rates.
The classic examples: a museum cafe open to the public, advertising sold in your newsletter, or renting out facilities in certain ways. Plenty of activities have exceptions — volunteer-run efforts and genuine donations usually don’t count — which is exactly why UBIT is worth a quick check with someone who knows the rules rather than a guess. The IRS explains the basics on its Unrelated Business Income Tax page and the About Form 990-T page.
It depends entirely on your state, and this is where the “we don’t pay taxes” assumption causes the most surprises. Federal exemption does not automatically exempt you from state sales tax or local property tax — those are governed state by state, and the rules are genuinely inconsistent. Some states exempt your purchases, some don’t, and some even require your nonprofit to collect and remit sales tax on the things you sell.
Property tax is similar: many nonprofits are exempt on property used for their exempt purpose, but it often requires a separate application and varies by locality. The practical move is to confirm your state’s specific rules rather than assume — a short conversation now prevents an awkward assessment later. Keeping clean, well-categorized books (see our nonprofit chart of accounts guide) makes any of these filings far easier when they do apply.
The takeaway isn’t “you owe more than you thought” — it’s “know which boxes apply to you.” For most small nonprofits, the reality is simple: file your 990, run payroll correctly, watch for unrelated business income, and confirm your state’s sales and property rules once. Do those four things and the “do we owe taxes?” question stops being scary.

Common tax questions from small 501(c)(3) organizations.
Generally no. A 501(c)(3) pays no federal income tax on income related to its exempt mission, which is the core benefit of the status. The main exception is unrelated business income, which can be taxable under UBIT even though mission income is not.
Form 990 is an information return, not a tax bill. It reports how your organization raised and used its money so the IRS and the public can see it. You generally owe no tax on mission income, but filing is required — missing it for three consecutive years causes automatic loss of exempt status.
Yes. If you have paid staff, you withhold federal income tax and the employee’s share of Social Security and Medicare (FICA) and pay the matching employer share, just like any employer. 501(c)(3)s are exempt from federal unemployment tax (FUTA), but state unemployment rules vary.
UBIT is unrelated business income tax — income tax on profit from a trade or business that isn’t substantially related to your mission. If your gross unrelated business income is $1,000 or more in a year, you file Form 990-T and may owe tax at standard corporate rates.
It depends on your state. Federal exemption does not automatically exempt you from state sales tax. Some states exempt nonprofit purchases, some don’t, and some even require nonprofits to collect and remit sales tax on the goods or services they sell. Confirm your state’s specific rules.
Often they’re exempt on property used for their exempt purpose, but it varies by state and locality and frequently requires a separate application. Don’t assume exemption is automatic — confirm with your local assessor.
