1. What Is Alternative Minimum Tax (AMT)?
The Alternative Minimum Tax (AMT) is a supplemental income tax imposed by the United States federal government on individuals, corporations, estates, and trusts that have certain items that receive special treatment under the tax law. The AMT is designed to ensure that these entities pay a minimum amount of tax, regardless of deductions, credits, and exclusions that may significantly reduce their regular tax liability.
The AMT operates by disallowing certain deductions and credits allowed under the regular income tax system. It then applies a separate, lower tax rate to the adjusted income. If the resulting AMT liability exceeds the taxpayer’s regular tax liability, the taxpayer must pay the higher AMT amount.
1.1. Historical Context and Purpose
The AMT was introduced in 1969 in response to reports that some wealthy individuals were using various tax loopholes to avoid paying any income tax. The original intent was to ensure that all taxpayers, regardless of income level or access to tax planning strategies, contribute their fair share to the federal government.
Over the years, the AMT has undergone several changes and adjustments. However, its fundamental purpose remains the same: to prevent high-income taxpayers from using deductions and credits to eliminate their tax liability entirely.
1.2. Who Is Subject to the AMT?
While the AMT was initially targeted at high-income earners, it can affect taxpayers at various income levels, especially those who claim certain deductions or credits. Common factors that may trigger the AMT include:
- High state and local taxes
- Numerous personal exemptions
- Incentive stock options
- Accelerated depreciation
- Private activity bonds
1.3. How the AMT Works
The AMT calculation involves several steps. First, taxpayers must calculate their regular taxable income. Then, they must add back certain deductions and exemptions that are not allowed under the AMT rules. This adjusted income is known as Alternative Minimum Taxable Income (AMTI).
Next, taxpayers subtract an AMT exemption amount, which varies based on filing status. The remaining amount is then multiplied by the AMT tax rate. The AMT tax rate is generally lower than the regular income tax rates, but because the AMT disallows many common deductions, the resulting tax liability can still be significant.
Finally, taxpayers compare their AMT liability to their regular tax liability. If the AMT liability is higher, they must pay the difference in addition to their regular taxes.
