Form 990 is the annual federal information return most tax-exempt organizations use to report their mission, programs, finances, pay, governance and compliance to the IRS and the public. The law says an organization must make it available for public inspection, and an authorized officer signs it under penalties of perjury. The form asks what board review took place, but federal tax law does not require the board to review or approve it. Good practice is for the board to understand the public story the return tells and to review it through named owners.
Many people call Form 990 the nonprofit tax return. That is familiar, but it misleads. A better name is a public information return: a record of what an organization says it did, how it raised and spent money, who runs it and how it is governed. Most tax-exempt organizations, not all, have a 990-series filing every year. A paid preparer may build the return, but it belongs to the organization, and the board is accountable for the story it tells. This guide is based on the 2025 Form 990 and its instructions, and it links to a deeper article on each question.
What is Form 990, and why is it more than a tax return?
Form 990 is an annual information return required of most organizations exempt from income tax under section 501(a). The IRS instructions say the form gives the IRS the information required by section 6033. It is not mainly a tax calculation. An organization that earns unrelated business income reports that on a separate Form 990-T.
Think of Form 990 as a public record assembled from tax, accounting, program, people and governance facts. The IRS and the filing organization must make the completed return available to the public, and the instructions note that some members of the public rely on it as their primary or only source of information about an organization. Donors, funders, reporters, regulators and prospective directors all read it. States can also require a copy to meet their own reporting rules.

Which Form 990 does a nonprofit file?
The IRS routes organizations by gross receipts and year-end assets. This is a first-pass map, not a diagnosis. The IRS chart is on its which-forms page.
| If the organization has | It files |
|---|---|
| Gross receipts normally $50,000 or less | Form 990-N, the e-Postcard, or it may choose Form 990-EZ or the full Form 990 |
| Gross receipts under $200,000 and total assets under $500,000 | Form 990-EZ or the full Form 990 |
| Gross receipts of $200,000 or more or total assets of $500,000 or more | The full Form 990 |
| A private foundation | Form 990-PF |
Dollar limits can change. Check the instructions for your tax year.
Then qualify it. Churches and certain church-related, governmental, political, supporting and other organizations follow exceptions or special rules, and some organizations must use the full form whatever their size. An organization can also owe Form 990-T or another filing. “Nonprofit” under state law and “tax-exempt” under federal law are not the same thing. For the details, including how gross receipts are figured, see Form 990 for small nonprofits.
Who is responsible for Form 990, and who signs it?
The organization is responsible for a complete and accurate return. The instructions say that using a paid preparer does not relieve the organization of that responsibility. A preparer applies the reporting rules and asks for support, but cannot know facts the organization does not give. Facts come from inside the organization:
| Fact | Usually owned by |
|---|---|
| The ledger, reconciliations and financial statements | Finance |
| Program descriptions and results | Program leaders |
| Pay support and employee counts | HR and payroll |
| Contribution records | Development |
| The board, policies and relationships | The board chair, secretary and governance committee |
| Applying the reporting rules and preparing the return | The preparer |
These roles are practice, not law. Change them to fit your staff.
An officer authorized to sign as of the filing date signs under penalties of perjury. The instructions name the president, vice president, treasurer, assistant treasurer, chief accounting officer or another corporate officer, such as a tax officer. If your usual signer is not an officer, call a specialist. See who signs Form 990.
Federal tax law does not require the board to review or approve the return. Part VI, line 11a asks whether a complete copy went to all members of the governing body before filing, and line 11b asks how any review happened. Answer with what actually happened. Our article on whether the board has to approve the Form 990 shows how.
What should the board review before Form 990 is filed?
Good practice is a question, an owner, a date and proof. Six questions are enough to start. Review means checking the return’s material facts and public story. It does not mean directors prepare tax schedules.
- Are the legal name, exempt classification and filing year correct?
- Do the mission and program descriptions match what the organization actually did?
- Do the headline revenue, expense, asset, liability and pay figures match reliable records?
- Are the answers on governance, independence, policies, related parties and the pay process true?
- Is every required schedule attached, and does each agree with the main form?
- Has someone checked both the filing copy and the version meant for public disclosure?
Here is a fictional example. River Arts Collaborative is a made-up calendar-year public charity with $1.6 million in gross receipts. Its CPA sends a draft five days before the deadline. The treasurer finds that Part III describes an after-school program the board ended in August, that line 11a says “Yes” although only the finance committee saw the return, and that the proposed public PDF holds a contributor attachment no one has reviewed.
The directors do not rewrite the return in the meeting. The chief executive corrects the program facts. The board secretary writes the review that really happened on Schedule O, and either the corrected final reaches every director before filing or line 11a becomes “No.” The finance lead and the preparer check the public copy. The board sets a deadline and keeps the IRS acceptance. The teaching point: good oversight is not “it looks fine.” It is a question, an owner, a date and evidence that the answer reached the filed return.
To do this yourself, use the twelve-question checklist, the 15-minute scan and the check of your own line. The free download below puts all three on paper.
What happens if Form 990 is late, rejected or missed?
The return is generally due on the 15th day of the fifth month after the tax year ends. For a calendar-year organization that is May 15, moved to the next business day if it falls on a weekend or legal holiday. The IRS due-date table lists the dates for other year-ends. Eligible organizations can request an automatic six-month extension on Form 8868 by the original due date, but Form 8868 cannot extend Form 990-N, and it does not extend time to pay tax.
A 2025 Form 990 must be e-filed. Publication 4163, written for e-file providers, says an e-filed return is not considered filed until the IRS accepts it. A “sent” screen is not acceptance, so save the IRS acceptance.
Late or incomplete returns can bring penalties, and three missed years in a row end tax-exempt status automatically. We do not print penalty amounts, because they change. The IRS cannot undo a proper automatic revocation, and the organization must apply for reinstatement. The full picture is in Form 990 late or missed. The useful action is an owned filing calendar with a backup, not a scare.
What becomes public after Form 990 is filed?
In general, the whole return, including its schedules and attachments. The IRS public disclosure overview says the return includes any schedules and attachments filed with the form. Names, titles and pay in Part VII are public, and so is Schedule O. Most organizations are not required to make contributor names and addresses on Schedule B public, but private foundations and section 527 organizations are, and other Schedule B information can still be public. Do not promise donors that their names are always private.
Keep a controlled filed copy and a separately checked public copy. Never put Social Security numbers on the return. Do not redact casually: ask the preparer to prepare the public copy by the current instructions. Accuracy is not public relations. The aim is a complete return whose public story agrees with your records. For how to provide copies and what to check first, see is Form 990 public.
What is changing, and where should you go next?
Form 990 changes, and not every change is final. As of October 31, 2026, the 2025 form is final, the 2026 form is a draft and Treasury’s plan to add reporting on government grants and fiscal sponsorship is only a plan. Our status report labels each item.

Based on the 2025 Form 990 and its instructions, checked against the IRS pages on October 31, 2026. The IRS has posted a draft 2026 form, which keeps Part VI, lines 11a and 11b at the same numbers, but drafts can change. Filing rules depend on your organization’s classification, facts, tax year and state. This guide is general education, not legal, tax or accounting advice.
