If an employee is involuntarily terminated, his/her personnel records must be retained for one year from the date of termination. Under ADEA recordkeeping requirements, employers must also keep all payroll records for three years.
The length of time you must keep the records depends on the type of records involved. Supplementary basic records, (i.e., basic employment and earnings records and wage rate tables), order, shipping, and billing records, and records of additions to or deductions from wages paid, are required to be kept for two years.
