President Obama, using the autopen, signed the American Taxpayer Relief Act of 2012 (the “Act”) into law on January 2, 2013. The following is a summary list of the Act’s major changes to and extensions of prior law. We will keep you informed of possible important updates resulting from a comprehensive tax reform.
Individual Income Tax Rates. The Act keeps in place the Bush-era income tax rates for most individuals (staying at 10%, 15%, 25%, 28%, 33%, and 35%) except that the highest marginal income tax bracket rises to 39.6% for individual filers whose taxable income is more than $400,000 ($450,000 for joint filers and for qualifying surviving spouses; $425,000 for qualifying heads of households; and $225,000 for married taxpayers filing separately).
Medicare Taxes. The Act does not affect the Medicare taxes effective in 2013. There will thus be an additional 0.9% Medicare tax on wages over $200,000 for single individual filers ($250,000 for joint filers and qualifying surviving spouses; $200,000 for qualifying heads of households; and $125,000 for married taxpayers filing separately). The 3.8% Medicare tax on certain net investment income also starts to apply to single individual filers with modified adjusted gross income over $200,000 ($250,000 for joint filers and for qualifying surviving spouses; $200,000 for qualifying heads of households; and $125,000 for married taxpayers filing separately).
