http://www.nytimes.com/2006/04/16/us/16tax.htmlUnless Congress takes action, one in four families with children — up from one in 22 last year — will owe up to $3,640 in additional federal income tax come next April.
Few of them realize that their taxes have increased, because Congress has not voted to raise taxes. Instead, Congress let a tax break expire. That break limited the alternative minimum tax, which takes back part of the tax cuts sponsored by President Bush.

The expiration of the A.M.T. patch and the tax break for investment income almost balance each other out this year, according to the Tax Policy Center, a nonprofit organization whose computer model of the tax system has been deemed reasonable and reliable by the Bush administration. The impact will be felt primarily among taxpayers of two different income levels.
The A.M.T. will cost Americans who earn $50,000 to $200,000 nearly $13 billion more next April. That is about how much people who earn more than $1 million will save because of the break on investment income like dividends and capital gains. Both figures were provided by the Tax Policy Center, which is a joint project of the Brookings Institution and the Urban Institute.
