How to Fill Out Form 990 (2026): Nonprofit Return Guide

Form 990 is the annual information return that tax-exempt organizations file with the IRS. It reports revenue, expenses, governance, and compensation. For calendar-year organizations, the 2026 return is due May 17, 2027.

What's new for 2026:

The daily late filing penalty for large organizations rises to $135 for 2026 returns.
May 15, 2027 falls on a Saturday, so the due date moves to Monday, May 17. Form 8868 extends it to November 15, 2027.
Nonprofits now need a Single Audit once they spend $1,000,000 or more in federal grant funds in a year, up from $750,000, for fiscal years beginning on or after October 1, 2024.

Most nonprofits owe no tax on this return, but it is fully public. Donors, grantmakers, and charity rating sites read it, so the expense breakdown and governance answers matter as much as the numbers.

Part	What to enter	Where it comes from in your books
Part I: Summary	Headline revenue, expenses, net assets, employees, and volunteers	Calculated from the parts below. Review it last, since readers see it first

Part IV: Schedules checklist	Yes/no questions that decide which schedules you must attach	Your activities, grants, and governance records

Worked example: a $1.2 million community health nonprofit

Revenue (Part VIII): $700,000 in government grants, $350,000 in individual and foundation contributions, and $150,000 in program service fees, for $1,200,000 total.

Functional expenses (Part IX):

Expense	Total	Program	Management and general	Fundraising
Salaries (allocated 75/15/10 by time records)	$650,000	$487,500	$97,500	$65,000
Rent (allocated 80/15/5 by square footage)	$120,000	$96,000	$18,000	$6,000
Direct program costs	$240,000	$240,000
Audit and accounting	$40,000		$40,000
Fundraising consultant and donor outreach	$50,000			$50,000
Total	$1,100,000	$823,500	$155,500	$121,000

About 75% of spending goes to programs, the ratio grantmakers and rating sites check first. That split is only defensible if salaries and rent are allocated on a documented basis during the year, such as time records and square footage, not estimated in April when the return is being prepared.

Your Form 990 prep checklist

When	Task
Throughout the year	Tag every expense by function (program, management and general, fundraising) in the books
Throughout the year	Track restricted gifts separately from unrestricted ones
Year-end	Close the books and reconcile contribution revenue to the donor database
January	Pull compensation figures from W-2s and 1099s for Part VII
February to March	Complete the audit or review, if required by grants or your state
Before the board meeting	Share the draft Form 990 with the board. Part VI asks whether you did
By May 17, 2027	E-file the return or file Form 8868 to extend

Common mistakes to avoid

Estimating functional expenses at filing time. After-the-fact allocations produce ratios that look made up. Allocate salaries and shared costs monthly using time records and square footage.
Filing the wrong version. An organization that crosses $200,000 in gross receipts or $500,000 in assets must move from Form 990-EZ to the full Form 990.
Publishing donor names. Schedule B donor names and addresses must not appear in the public copy for most organizations. Check the public PDF before posting it.
Mixing restricted and unrestricted funds. Part X requires net assets split by donor restriction. If your books do not track restrictions, the balance sheet cannot be completed accurately.
Missing three years of filings. Organizations that do not file for three consecutive years, including the 990-N, lose tax-exempt status automatically.

If you file late or get it wrong

Late filing penalties are charged for each day the return is late and are adjusted for inflation each year. Large organizations pay $135 per day for 2026 returns, up to a maximum cap. Smaller organizations pay a lower daily rate, capped at the lesser of a fixed amount or 5% of gross receipts. An incomplete return can be penalized the same way as a late one. If you find an error after filing, file an amended Form 990 by checking the "amended return" box.

Nonprofit callout: government-funded organizations

Nonprofits that spend $1,000,000 or more in federal grant funds in a year need a Single Audit for fiscal years beginning on or after October 1, 2024, and the audited financials feed directly into Parts XI and XII. Government grants must also be reported separately from other contributions in Part VIII, because they count differently in the Schedule A public support test. Keep grant revenue and spending tracked by grant from the start of the year. Confirm your organization's audit and reporting requirements with your CPA before relying on these notes.

Frequently asked questions

Do nonprofits pay tax on Form 990?

Generally no. Form 990 is an information return, not a tax return. Tax is owed only on unrelated business income, which is reported on Form 990-T.

Is our Form 990 really public?

Yes. Anyone can request it from your organization or view it on IRS and third-party databases. The main exception is donor names and addresses on Schedule B, which most organizations do not have to disclose publicly.

Can we file Form 990-N if our receipts were unusually high one year?

The 990-N test uses gross receipts that are "normally" $50,000 or less, which generally means an average over several years rather than a single year. If one large gift pushes your average over the limit, you will need to file Form 990-EZ or Form 990 for that year.
