This easy to use online alternative minimum tax (AMT) calculator estimates your tax liability after exercising Incentive Stock Options (ISO).

You will only need to pay the greater of either your Regular Income Tax Owed or your AMT Tax Owed, so being as detailed as possible is important to tax planning. If you have our Premium membership, try and input as many of your deductions, capital gains, and ISO grants that you know of or can predict you will have by end of year.
