Vermont Congressman Peter Welch, and New Hampshire Democrats Paul Hodes and Carol Shea-Porter were on the winning side as the House voted to protect more than 20 million mostly upper-income taxpayers in danger of being slapped with a tax increase.
The House voted on Wednesday to fix the alternative minimum tax, which would have hiked taxes an average of $2,300 for many taxpayers.
Without a fix, the number of taxpayers swept up by the alternative minimum tax could balloon from around 4 million to between 25 million to 30 million.
The tax was enacted in 1969 to catch a small number of very rich tax dodgers, but the tax now hits many more people because it was never adjusted for inflation.
The plan now moves to the Senate.
