|| Tax laws provide tax benefits for certain kinds of income and allow special deductions and credits for certain expenses.
|| These benefits can drastically reduce some taxpayers’ tax obligations.
|| Congress created the AMT in 1969, targeting higher-income taxpayers who could claim so many deductions they owed little or no income tax.
||Because the AMT is not indexed for inflation, a growing number of middle-income taxpayers are discovering they are subject to the AMT.
||You may have to pay the AMT if your taxable income for regular tax purposes plus any adjustments and preference items that apply to you are more than the AMT exemption amount.
||The AMT exemption amounts are set by law for each filing status.
