How common are single audit findings among Illinois nonprofits?
Each row counts one report per organization for that audit year, nonprofit auditees only. A rate is shown as a count over its denominator because a percentage on its own cannot be checked.

10 of 11 audit years had at least 100 nonprofit reports and are shown; a rate over a dozen reports is not a rate. How we decide what to publish.
How does Illinois compare with the national rate?
Nationally in audit year 2025, 2,715 of 19,478 (13.9%) nonprofit single audits reported at least one finding, and 1,476 of 19,478 (7.6%) reported a material weakness. The Illinois figures above are on the same basis, so the two can be read together.
Which finding types are most common?

How we computed this
Counts come from the Federal Audit Clearinghouse, one report per organization and audit year, nonprofit auditees only, for Illinois. A resubmission supersedes the filing it replaces rather than being counted twice. An audit year with fewer than 100 nonprofit reports is not published.
