The American Taxpayer Relief Act of 2012:
1) Allowed Bush-era tax rates to expire for individuals earning over $400,000 and families over $450,000, raising their tax rate to 39.6%;
2) Permanently patched the AMT by increasing exemption amounts; and
3) Provided for a maximum 40% estate tax and $5 million exemption.
It effectively raised taxes for all by not extending a payroll tax cut and delayed mandatory spending cuts. Congress will revisit tax and spending policies when addressing the debt limit in February, with entitlement reforms and the "chained CPI" likely to be controversial topics.
