The Alternative Minimum Tax (AMT) is a parallel tax system designed to ensure that corporate and high-income noncorporate taxpayers pay a minimum level of tax, regardless of the deductions and credits they may otherwise be eligible for. It aims to limit the benefits of certain deductions to ensure tax liabilities align better with actual income.
What is the Alternative Minimum Tax?
The AMT is calculated at a flat rate of 26% or 28% for individuals, and 20% for certain corporations. This rate is applied to the taxpayer’s Alternative Minimum Taxable Income (AMTI), which includes taxable income plus certain adjustments and preferences. Taxpayers must pay the greater of their regular tax liability or their AMT liability.
Calculation of the Alternative Minimum Tax
- Determining AMTI:
$$ \text{AMTI} = \text{Regular Taxable Income} + \sum \text{Tax Preference Items} + \sum \text{Adjustment Items} $$
- Applying the AMT Rate:
$$ \text{AMT Liability} = \text{AMTI} \times \text{AMT Rate} $$
Types of Tax Preferences and Adjustments
- Tax Preference Items: These are specific deductions and credits that the IRS identifies as potentially reducing taxable income below what Congress deems fair. Examples include excess intangible drilling costs and tax-exempt interest from private activity bonds.
- Adjustments: This consists of items such as the difference between AMT and regular tax depreciation, and the effect of incentive stock options.
Historical Context and Applicability
The AMT was introduced in 1969 to ensure that high-income individuals and profitable corporations could not avoid paying federal income tax through legal tax avoidance strategies. Over the years, the scope of the AMT has broadened to cover a wider range of taxpayers.
