New Corporate Alternative Minimum Tax (AMT) Requirements

As we move into the new year, I would like to inform you about the latest requirements for the Corporate Alternative Minimum Tax (AMT) established by the Inflation Reduction Act of 2022. To assist in your tax preparation and planning, here is a summary of the critical aspects of the corporate AMT based on IRS announcements:

Form 4626 for Corporate AMT:

  • The IRS has released a draft Form 4626, designated for calculating the corporate AMT for the 2023 tax year.

  • All corporations, unless excluded, must file Form 4626 with their tax returns to assess whether they are an "applicable corporation" for the AMT, and to calculate the AMT due, if applicable.

Safe Harbor and Simplified Method:

  • Draft instructions detail a safe harbor, simplified method for determining if a corporation is affected by the AMT.

  • Corporations not classified as "applicable corporations" under this safe harbor do not need to file Form 4626 for the first tax year post-2022.

Filing Exclusions:

  • Certain entities such as S corporations, regulated investment companies, and real estate investment trusts are excluded from filing the Form 4626.

Corporate AMT Thresholds:

  • The corporate AMT imposes a 15% minimum tax on the adjusted financial statement income (AFSI) of corporations with over $1 billion in AFSI.

  • For companies with foreign parents, an additional $100 million income threshold applies.

Interim Rules and Guidance:

  • Several notices have provided interim rules and guidance, which taxpayers can rely upon for a limited time, including the 2023 tax year.

  • These notices include initial applications of the corporate AMT, interim guidance on insurance-related issues, relief from certain underpayment penalties, and additional applications of the corporate AMT.

It's essential for your corporation to review these new AMT requirements and understand how they may impact your tax obligations. If your corporation has substantial AFSI, it's crucial to determine whether you fall within the scope of the new AMT and prepare accordingly.
