Summary

The AMT uses two rates: 26% on the first portion and 28% on amounts above the threshold. It applies when the tentative minimum tax exceeds regular tax.

You do not owe AMT because your regular tax of $57,063 exceeds the tentative minimum tax of $45,994.

The AMT exemption phases out at 25 cents per dollar of AMTI above the phase-out threshold, which can significantly increase AMT for high-income taxpayers.

Common AMT triggers include large SALT deductions, ISO exercise spreads, and accelerated depreciation differences.
