Schedule A (Form 1040) - Reduction of Itemized Deductions
1
In 2013, the IRS began limiting itemized deductions. For 2015, itemized deductions may be reduced for taxpayers with Adjusted Gross Income (AGI) above:
  • $309,900 for married filing joint or qualifying widow(er)
  • $284,050 for head of household
  • $258,250 for single
  • $154,950 for married filing separate

If your AGI exceeds the amount listed for your filing status, your itemized deductions will be reduced by the lesser of:
  • 3% of the AGI above the amount listed for your filing status or
  • 80% of the amount of itemized deductions otherwise allowable

This reduction does not apply to medical and dental expenses, investment interest, or casualty or theft losses.
