Businesses Impacted by ERC Amendments Should Review IRS Penalties Now

Read time: minutes

Many businesses that claimed the Employee Retention Credit (ERC) later filed amended income tax returns to reduce wage deductions as required by law.

Those amended returns often resulted in additional tax liabilities, and many business owners subsequently paid IRS penalties and interest.

A recent court decision, Kwong v. United States (U.S. Court of Federal Claims, Nov. 25, 2025), may provide a path for some taxpayers to seek refunds or abatements of penalties and interest that accrued during the COVID disaster period.

Businesses may want to consider a review if they:

  • Claimed the Employee Retention Credit (ERC)
  • Filed amended income tax returns adjusting wage deductions
  • Owed additional tax because of those amendments
  • Paid IRS penalties or substantial interest


The decision is not yet final, and future appeals remain possible. However, many advisors believe taxpayers should preserve their rights by filing protective claims before applicable deadlines expire.

For many taxpayers, the key deadline is expected to be July 10, 2026.
