Prevents an IRS rule that would simplify how some large businesses pay a minimum tax.

This resolution would stop an IRS rule that aimed to make it simpler for certain large businesses, specifically partnerships, to calculate their Corporate Alternative Minimum Tax. If passed, the IRS's "simplifying" guidance would not take effect. This means the existing, potentially more complex, way of applying this tax to partnerships would continue.

What Would Change

Today, the IRS has issued guidance (IRS Notice 2025-28). It aims to simplify how certain large businesses structured as partnerships calculate their Corporate Alternative Minimum Tax. If this resolution passes, that specific IRS guidance would be canceled and would not take effect. This means the current, potentially more complex, methods for applying the Corporate Alternative Minimum Tax to partnerships would remain in place. The intended simplification would not happen.
