Understanding the Results

Result 1: AMT Taxable Income

Once all inputs are entered, the calculator will compute your AMT Taxable Income using the formula: ordinary income + long-term capital gains – AMT exemption + state and local taxes.

Result 2: Alternative Minimum Tax

The Alternative Minimum Tax (AMT) is then calculated as 26% of your AMT taxable income.

Result 3: Regular Taxable Income

Your Regular Taxable Income is calculated by subtracting itemized deductions from the sum of ordinary income and long-term capital gains.

Result 4: Regular Tax

The Regular Tax amount is determined by calculating 24% of your regular taxable income.

Result 5: AMT Difference

The calculator will then compute the AMT Difference using the formula: maximum of (AMT – Regular Tax, 0). This represents the additional tax liability specific to AMT requirements.

Result 6: Total Tax Liability

Finally, the total tax liability is obtained by adding your regular tax and the AMT difference together, providing a complete view of your tax obligations.
