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 PERKINS COUNTY RURAL WATER SYSTEM, INC 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.
