Nonprofit Compliance Checklist

Category 1: Federal Tax Filings

Every 501(c)(3) organization files an annual information return with the IRS, the specific form depending on its gross receipts and total assets:

• Form 990-N, a short electronic notice, for organizations with gross receipts normally $50,000 or less.
• Form 990-EZ or the full Form 990, for larger organizations, depending on gross receipts and total assets.
• Form 990-PF, for private foundations regardless of size.

The return is due the 15th day of the 5th month after your fiscal year ends, May 15 for a calendar-year organization. If your organization has unrelated business income of $1,000 or more in a year, it also owes a separate Form 990-T, in addition to its regular annual return, per the IRS. Missing the required annual return for three consecutive years automatically revokes tax-exempt status, with no advance warning beyond the missed deadlines themselves; reinstatement then means reapplying to the IRS and paying the user fee again, not just filing the overdue returns.

Category 2: State Corporate Filings

Separate from the federal return, most states require your nonprofit corporation to file its own annual or biennial report with the state's business filing agency, confirming your registered agent and officer information, similar to what a for-profit corporation files. You also have to maintain a registered agent at a physical address in your state of formation continuously, not just at incorporation; see our guide on does a nonprofit need a registered agent for what that role covers. If your nonprofit operates, hires staff, or owns property in a state other than where it incorporated, it may also need to register there as a foreign nonprofit corporation.

Category 3: Board Governance

Most state nonprofit corporation statutes expect an annual meeting of the board of directors, and Form 990 itself asks a series of governance questions, including whether the organization has a written conflict of interest policy, a whistleblower policy, and a document retention policy, and whether it keeps minutes of board and committee meetings. None of these governance documents are a one-time task completed at formation; a conflict of interest policy only works if directors actually sign a disclosure statement periodically, and minutes only help if every meeting produces them, not just the first one.

Category 4: Fundraising Registration

If your nonprofit solicits donations from the public, roughly 40 states require a separate charitable solicitation registration before you do, renewed annually, often alongside a copy of your Form 990. A handful of states, including Delaware, Texas and Wyoming, have no general requirement. This registration follows where you solicit, including through an online donation page accessible nationwide, not only where you're incorporated; see multi-state charitable registration explained if you fundraise across state lines.

Building a Single Combined Calendar

Because these four categories run on different schedules, set by different agencies, the most reliable way to stay current is one combined calendar rather than four separate ones tracked by different people. List your federal Form 990 deadline, your state corporate filing deadline, your board's annual meeting date, and every state charitable registration renewal date together, and review it at the start of each fiscal year. For a deadline-by-deadline version of this same calendar organized across a full year, see nonprofit compliance checklist by year.

What Happens When Something Is Missed

A single missed state filing usually triggers a grace period and a late fee before anything more serious happens; a single missed Form 990 triggers no immediate consequence beyond the next year's filing becoming more urgent. The real risk compounds: three consecutive missed federal returns means automatic revocation, and repeated missed state filings can lead to administrative dissolution of the corporation itself. Treat any missed deadline as an item to fix immediately, not something to let ride into a second year.

A Checklist Only Works if Someone Owns It

Many small nonprofits rely on a volunteer board member or part-time staffer to track compliance, and that knowledge can disappear when that person moves on. Assign compliance ownership explicitly, and keep the calendar itself with the organization's permanent records rather than in one person's personal files.

Growth Can Change Which Form You File

If your gross receipts or total assets grow past the Form 990-N or 990-EZ threshold during the year, you may owe a more detailed return than you filed previously. Check your current-year numbers against the thresholds each year rather than assuming last year's simplest form still applies.

A Compliant Nonprofit Still Benefits From a Second Set of Eyes

Even a nonprofit current on every filing can miss a subtler governance gap, such as a conflict of interest policy that exists on paper but is never actually used when a real conflict comes up. An annual internal review, separate from the filing checklist itself, catches gaps a deadline calendar alone will not.

This Is Not Legal or Tax Advice

Specific deadlines, thresholds, and state requirements depend on your organization's size, activities, and state of formation. Talk to a nonprofit accountant or attorney to confirm your organization's full compliance obligations.
