Payroll Record Retention

Payroll might run on deadlines, but it’s built on documentation. From timecards and tax filings to employee onboarding forms, knowing what to keep — and for how long — isn’t just good housekeeping, it’s a compliance safeguard.

Federal regulations like the Internal Revenue Service (IRS) and the U.S. Department of Labor (DOL) set clear record-retention standards, and Pennsylvania employers must also follow guidance from the Pennsylvania Department of Revenue and the Pennsylvania Department of Labor & Industry.

For payroll professionals and business owners alike, understanding these requirements is key to avoiding penalties, responding confidently to audits, and protecting your organization. In the matrix below, we break down federal and Pennsylvania payroll record-retention rules, along with best recommended practices for each category.

Electronic recordkeeping

PremierNow and isolved have you covered with our HR solutions! You do not need to keep physical, paper payroll records. IRS and Department of Labor (FLSA) regulations permit electronic storage, provided the records are accurate, secure, easily accessible for audits, and printable. Digital, cloud-based systems are generally preferred for efficiency and security, though they must ensure data integrity and compliance.
