TPC Tax Calculator Shows What Avoiding Fiscal Cliff Means for Taxpayers

Following Congress’s last minute passage of legislation averting a plunge off the fiscal cliff, TPC has released a new Tax Calculator that lets users examine the effects of the American Taxpayer Relief Act of 2012 (ATRA). As with earlier versions, the new calculator compares income and payroll tax liabilities under alternative scenarios:

  1. ATRA, the tax law that will apply in 2013.
  2. 2012 tax law (with an AMT patch). This is what you paid in 2012, including the now-expired payroll tax cut and a patched AMT.
  3. Pre-ATRA 2013 tax law. This is what you would have paid if Congress hadn’t acted and we’d gone over the fiscal cliff for all of 2013.

(More details on these plans, including their treatment of the AMT and estate taxes, are available here.)

To make things easy, you can look at ready-made examples or create your own case.
