The tax items for 2013 of greatest interest to most taxpayers include the following changes.
- Beginning in tax year 2013 (generally for tax returns filed in 2014), a new tax rate of 39.6 percent 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 percent — remain the same as in prior years. The guidance contains the taxable income thresholds for each of the marginal rates.
- The standard deduction rises 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.
- The American Taxpayer Relief Act of 2012 added a limitation for itemized deductions claimed on 2013 returns of individuals with incomes of $250,000 or more ($300,000 for married couples filing jointly).
- The personal exemption rises 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.)
