What Triggers the Alternative Minimum Tax?

Certain financial activities can trigger the AMT, increasing your tax liability.

Additionally, high state and local tax deductions or certain types of investment income can also push you into AMT territory. Using an AMT tax calculator can help you identify these triggers and plan accordingly.

How to Use the AMT Calculator for ISO Exercises

Exercising Incentive Stock Options (ISOs) can significantly impact your AMT liability. Our ISO AMT calculator helps you estimate the tax implications by factoring in the spread between the exercise price and the fair market value of the stock. This is essential for employees who receive ISOs as part of their compensation package.

Understanding AMT Deductions

While the AMT disallows many deductions allowed under the regular tax system, some deductions are still available. These include medical expenses, mortgage interest on a primary residence, and certain charitable contributions. Our AMT calculator helps you identify which deductions apply to your situation and how they affect your overall tax liability. This makes it easier to plan and optimize your tax strategy.

AMT and Capital Gains: What You Need to Know
