Employer Audits

A complete payroll audit involves an examination of any subsidiary records, including payment records for services that were not classified as employment or wages. The Colorado Employment Security Act (CESA) 8-72-107 requires that all records must be open for inspection so that the records may be audited and verified at any reasonable time and as often as necessary. You are required to keep work records for a minimum of five years. More about employer audits>
