Frequently Asked Questions

What is the most important compliance deadline?

Form 990. If you miss filing with the IRS for three consecutive years, your 501(c)(3) status is automatically revoked. Everything else matters too, but this one can end your organization's tax-exempt status without warning.

What if I miss a state filing deadline?

Consequences vary by state. Many states impose late fees or interest. Some will administratively dissolve your nonprofit, which means you lose legal status, liability protection, and the ability to conduct business until you reinstate. Check your state guide for specific deadlines and consequences.

Do small nonprofits need to worry about compliance?

Yes. Even if your gross receipts are under $50,000, you still need to file Form 990-N (e-Postcard) annually, maintain your state registrations, and follow governance requirements. Small organizations are actually at higher risk because they often lack dedicated staff to track deadlines.
