1. What is Alternative Minimum Tax (AMT)?

The Alternative Minimum Tax (AMT) is a parallel tax system in the United States designed to ensure that high-income individuals, corporations, estates, and trusts pay at least a minimum amount of tax, regardless of deductions, credits or exemptions.

2. How Does the Calculator Work?

The calculator uses the basic AMT equation:

Where:

• \( AMTI \) — Alternative Minimum Taxable Income (USD)
• \( Exemption \) — AMT exemption amount (USD)
• \( 0.26 \) — 26% AMT rate (for this example)

Explanation: The equation calculates the tentative minimum tax by applying the AMT rate to income above the exemption amount.

3. Importance of AMT Calculation

Details: Calculating AMT is crucial for tax planning to determine whether you'll be subject to AMT and need to make estimated payments or adjust withholding.

4. Using the Calculator

Tips: Enter your Alternative Minimum Taxable Income and the applicable exemption amount. The calculator will compute your tentative AMT liability.
