The IRS recently extended the statute of limitations on ERC refunds by two years, giving itself a total of five years to conduct audits on businesses that may lack proper documentation proving their eligibility. Those businesses that have or will be applying for the ERC before it ends in 2024 (for 2020) and 2025 (for 2021) must file amended tax returns (941x) for any taxes already submitted. There is also no time limit for the IRS to audit what they believe to be false or fraudulent ERC claims intentionally filed to evade employer payroll taxes.
