Form 941-X — Adjusted Employer's Quarterly Federal Tax Return or Claim for Refund
Form 941-X is used to correct errors on a previously filed Form 941. It is also the form used to claim the Employee Retention Credit (ERC) retroactively for 2020 and 2021. For tax professionals, Form 941-X is one of the most consequential forms in recent years — the IRS has issued thousands of ERC audits and disallowance letters, and practitioners must be able to defend or correct ERC claims filed by clients.
