              Alternative Minimum Tax 
The tax laws give special treatment to some types of income and allow special deductions
and credits for some types of expenses. These laws enable some corporations with
substantial economic income to significantly reduce their regular tax. The purpose of the
corporate alternative minimum tax (AMT) is to ensure that these corporations pay a
minimum amount of tax on their economic income. A corporation owes AMT if its tentative
minimum tax is more than its regular tax.
Tentative minimum tax of a small corporation. For tax years
beginning after 1997, the tentative minimum tax of a small corporation is zero. This means
that a small corporation will not owe AMT.
Small corporation. For AMT purposes, a corporation is
a small corporation if it meets any of the following tests.
  1) This is its first tax year.
  2) This is its second tax year and its annual gross receipts for its first tax year were
  not more than $5,000,000.
  3) This is its third tax year and its average annual gross receipts for its first two tax
  years were not more than $5,000,000.
  4) This is its fourth tax year and its average annual gross receipts for its first three
  tax years were not more than $5,000,000.
  5) This is its fifth or later tax year and it meets both of the following tests.
  
    a) Its average annual gross receipts for its first 3-tax-year period
    beginning after 1993 were not more than $5,000,000.
    b) Its average annual gross receipts for all later 3-tax-year periods beginning after 1993
    and ending before the current tax year were not more than $7,500,000.
  
For these tests, gross receipts for a short tax year are annualized.
