How long do employers keep their quarterly tax reports?

Employers are generally required to keep their quarterly tax reports, such as Form 941, for at least four years from the date the tax was paid or the return was filed, whichever is later. This retention period ensures compliance with IRS regulations in case of audits or inquiries. Some employers may choose to retain records for longer periods for their own record-keeping purposes. It's also advisable to consult local laws, as some states may have different requirements.
