Enter your filing status, income, deductions and credits and we will estimate your total taxes for 2012. Based on your projected withholdings for the year, we can also estimate your tax refund or amount you may owe the IRS next April 2013. In 2012, Federal income tax rates were scheduled to increase to pre-2001 levels, but the 'Tax Relief, Unemployment Insurance Reauthorization, and Job Creation Act of 2010' left the existing tax brackets in place through 2012.
