Tax Calculator

I recently found this tax calculator (link at bottom of page) from the non partisan Tax Policy Foundation.  The calculator gives you an estimate of your federal tax burden under a variety of currently proposed scenarios. 

The three default scenarios are: full expiration of all Bush-era and Obama tax cuts, the Republican plan to extend the Bush-era tax cuts (H.R. 8, the Job Protection and Recession Prevention Act of 2012), and President Obama's plan to partially extend these cuts for families making under $250,000 per year ($200,000 for single filers) as well as extending tax cuts in the 2009 stimulus bill. Amounts shown are for tax year 2013, but this can be changed for other scenarios you might want to add. 

Don't forget to subtract any 401K, Deductible IRA and pretax health insurance premiums from your income as there are no separate lines for them in the calculator.   Also, if you click on the "detailed" button you can make it more accurate.
