Single audits by year

One row per audit year as the Federal Audit Clearinghouse accepted it. The auditor named is the one observed on that filing; CUSTER COUNTY is recorded in MILES CITY, Montana under EIN 816001347, and the Clearinghouse records it as a local government. Each report opens on the Clearinghouse itself; how to search the Federal Audit Clearinghouse explains the rest of the reporting package.

When is the next single audit due?

If CUSTER COUNTY is again required to have a single audit for the fiscal year ending Jun 30, 2026, the reporting package is due to the Federal Audit Clearinghouse by Mar 30, 2027 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.

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.

What findings did the auditor report?

The reference is the auditor’s; the requirement is the Compliance Supplement category the auditor selected. The finding text itself is not reproduced here; the FAC report linked above carries it in full. What the two severity levels mean: material weakness vs significant deficiency.

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 CUSTER COUNTY 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.
