The alternative minimum tax uses a different calculation that limits or adjusts certain regular-tax benefits. Owing AMT depends on the return as a whole, not simply whether someone describes themselves as a high earner.

Incentive stock option exercises, certain deductions, and other adjustments can be relevant. An expense that reduces regular taxable income may not produce the same result in the AMT calculation.

Before exercising substantial options or accelerating deductions, ask for a projection that considers both systems and the applicable filing-year rules. Keep grant documents, exercise confirmations, and prior AMT records so potential credits and carryovers are not overlooked.
