Congress has always adjusted the AMT in the past, and the IRS is preparing as if lawmakers will do so again, acting IRS Commissioner Steven T. Miller said in a recent letter to members of Congress. If lawmakers don't address the AMT, about 60 million taxpayers, nearly half of all individual filers, would have to wait until late March — if not later — to file their returns while the IRS reworks its systems, Miller said.
"Essentially, IRS has said it will be chaos — chaos! — trying to make it work," said Rep. Sander Levin of Michigan, the ranking Democrat on the tax-writing House Ways and Means Committee.
