In 2011, personal exemptions and standard deductions will rise and tax brackets will widen due to inflation related to eight tax provisions that were either modified or extended by the Tax Relief, Unemployment Insurance Reauthorization and Job Creation Act of 2010 that became law on Dec. 17. New dollar amounts affecting 2011 returns, filed by most taxpayers in early 2012, include the following:

• The value of each personal and dependent exemption, available to most taxpayers, is $3,700, up $50 from 2010.
• The new standard deduction is $11,600 for married couples filing a joint return, up $200, $5,800 for singles and married individuals filing separately, up $100, and $8,500 for heads of household, also up $100.
• Tax-bracket thresholds increase for each filing status. For a married couple filing a joint return, for example, the taxable-income threshold separating the 15-percent bracket from the 25-percent bracket is $69,000, up from $68,000 in 2010.
• The maximum earned income tax credit (EITC) for low- and moderate- income workers and working families rises to $5,751, up from $5,666 in 2010. The maximum income limit for the EITC rises to $49,078, up from $48,362 in 2010.
• The modified adjusted gross income threshold at which the lifetime learning credit begins to phase out is $102,000 for joint filers, up from $100,000, and $51,000 for singles and heads of household, up from $50,000.

Several tax benefits are unchanged in 2011. For example, the monthly limit on the value of qualified transportation benefits (parking, transit passes, etc.) provided by an employer to its employees remains at $230.

By law, the dollar amounts for a variety of tax provisions, affecting virtually every taxpayer, must be revised each year to keep pace with inflation.
