When is the next single audit due?
If FOUR RIVERS SANITATION AUTHORITY is again required to have a single audit for the fiscal year ending Apr 30, 2027, the reporting package is due to the Federal Audit Clearinghouse by Jan 31, 2028 at the latest.
Whether an audit is required depends on federal awards expended in that year (the single audit threshold). The rule, 2 CFR 200.512(a): the reporting package is due within 30 calendar days after the auditee receives the auditor's report or nine months after the end of the audit period, whichever is earlier; the date above is the nine-month date, moved to Monday when it falls on a weekend. Last verified: 2026-11-15.
Illinois also publishes audit reports of local governments: Illinois Office of Comptroller. Last verified: 2026-11-15.
Which federal programs did this organization report?
From the most recent accepted report, as listed on its schedule of expenditures of federal awards (SEFA). "Major" is the designation the auditor made under 2 CFR 200.518, not ours.
| ALN | Program | Expended | Major |
|---|---|---|---|
| 66.458 | CLEAN WATER STATE REVOLVING FUND | $5,502,706 | Yes |
| 66.458 | CLEAN WATER STATE REVOLVING FUND | $1,620,247 | Yes |

How we computed this
Every row comes from the Federal Audit Clearinghouse record named beside it, one report per audit year, with a resubmission superseding the filing it replaces. The auditor is the one named on that filing — it is not a statement about who audits FOUR RIVERS SANITATION AUTHORITY now. Form 990 figures come from the IRS e-filed return named by its object id. This page exists because the organization filed at least two single audits, or one with a finding.
