How long do employers have to keep payroll registers?

Employers are required to keep payroll registers for a minimum of three years, according to the Fair Labor Standards Act (FLSA). However, some states may have their own regulations that require longer retention periods. Additionally, it's advisable for employers to retain payroll records for at least four years to comply with the Internal Revenue Service (IRS) guidelines for tax purposes. Keeping records longer can also help in case of audits or disputes.
