Using this template.
Form 990 is part financial statement and part governance disclosure. The fastest filings pull structured data from your accounting system, not from scattered spreadsheets.
This checklist is a gather list for the long Form 990, Parts I through XII, plus the schedules most filers need. It is not Form 990-EZ or 990-N. Ask your preparer which return applies. It includes board and officer facts, conflict of interest documents, program accomplishments, related organizations and joint ventures, and revenue breakdowns. Net asset schedules should tie to your financials.
Federal tax law does not require the board to approve the return. Part VI asks whether each voting member received a complete copy of the final return before filing, and for a Schedule O description of the review process.
Work through the list with your finance lead and executive director at least six weeks before the deadline. If a policy or a fund balance is missing, fix the records before numbers go on the return.
Confirm every item against the current IRS instructions.
