MADISON—Last minute federal changes to the Alternative Minimum Tax (AMT) saved more than 20 million taxpayers from being affected by the additional tax. The increase in the AMT exemption amount was one of the most significant of the income tax law changes for 2007. Additional new rules for filers of 2007 state and federal returns may affect parents, educators, students, low- and middle-income filers, and those planning for retirement, according to the Wisconsin Taxpayers Alliance (WISTAX). Explanations of these changes and "plain-English" instructions for filing federal and state tax returns are available in Taxes08, WISTAX’s pocket tax guide. WISTAX is a nonprofit, nonpartisan organization dedicated to public-policy research and citizen education. (more)
