Nonprofit Tax Compliance: What Every 501(c)(3) Needs to Know

For 501(c)(3) organizations, tax compliance is the foundation of your exempt status. Here are the most critical things nonprofits must do to stay compliant, protect donors, and keep funding flowing.

File Form 990 Every Year

File Form 990, 990-EZ, or 990-N by the 15th day of the 5th month after your fiscal year ends. Miss three consecutive years and the IRS automatically revokes your tax-exempt status. Reinstatement is costly — prevention is the better strategy.

Acknowledge Every Donation Over $250

Provide written acknowledgment for any single donation of $250 or more. Include your EIN, donation date, amount, and confirm no goods or services were exchanged. Without this, your donor cannot legally claim the deduction.

Watch for Unrelated Business Income (UBIT)

Income from activities unrelated to your exempt mission may be taxable. Keep detailed records and consult a tax professional if your nonprofit earns revenue beyond its core programs.

Separate Program vs. Administrative Expenses

Funders and the IRS expect a clear breakdown between program services, management, and fundraising costs. Proper QuickBooks bookkeeping from day one makes this effortless at year-end.
