Source and scope
How the records were matched
- Federal expenditures are the total federal awards expended as reported in the organization’s public single audit. The audit shows the full fiscal date range and can include both direct and pass-through awards.
- Form 990 total revenue is the total revenue field in the IRS extract. It covers the filing’s revenue categories. The IRS publishes the end month in this extract, so the tax period may have a different start date or reporting scope from the audit.
- The match requires the same EIN and end month. We keep the latest accepted equivalent public audit and omit unclear audit spans or conflicting tax amounts. The IRS files cover returns filed in calendar years 2022–2024. Later audits may have an unavailable tax comparison in this collection.
- Read the figures separately. Audited award expenditures and Form 990 revenue use different accounting measures. The sources behind each figure are linked in the table.
