"The American Taxpayer Relief Act allows the Bush-era tax rates to sunset after 2012 for individuals with incomes over $400,000 and families with incomes over $450,000; permanently patches the alternative minimum tax (AMT); revives many now-expired tax extenders, including the research tax credit and the American Opportunity Tax Credit; and provides for a maximum estate tax of 40 percent with a $5 million exclusion. The bill also delays the mandatory across-the-board spending cuts known as sequestration."--Publisher website
