A related IRS release—IR-2013-4 [PDF 27 KB]—explains that:


  • Beginning in tax year 2013 (generally for individual income tax returns filed in 2014), a new tax rate of 39.6% has been added for individuals whose income exceeds $400,000 ($450,000 for married taxpayers filing a joint return). The other marginal rates—10%, 15%, 25%, 28%, 33%, and 35%— remain the same as in prior years. Rev. Proc. 2013-15 contains the taxable income thresholds for each of the marginal rates.
  • The standard deduction increases to $6,100 ($12,200 for married couples filing jointly), up from $5,950 ($11,900 for married couples filing jointly) for tax year 2012.
  • There is a limitation on itemized deductions claimed on a 2013 return of individuals with incomes of $250,000 or more ($300,000 for married couples filing jointly).
  • The personal exemption increases to $3,900, up from the 2012 exemption of $3,800. However, beginning in 2013, the exemption is subject to a phase-out that begins with adjusted gross incomes of $250,000 ($300,000 for married couples filing jointly). It phases out completely at $372,500 ($422,500 for married couples filing jointly.)
  • The alternative minimum tax exemption amount for tax year 2013 is $51,900 ($80,800, for married couples filing jointly), set by the American Taxpayer Relief Act of 2012, which indexes future amounts for inflation. The 2012 exemption amount was $50,600 ($78,750 for married couples filing jointly).
