A.M.T.
The A.M.T. has its own rules, including fewer deductions and just two tax rates, 26 percent and 28 percent. Taxpayers in the phase-out zone pay even higher rates on wage income than other people trapped by the A.M.T. The A.M.T. has become such a money maker that by 2008 its repeal would cost more than repealing the regular income tax, according to the Tax Policy Center, a joint venture of the Urban Institute and the Brookings Institution, two research institutions in Washington.
