2008 Adjusted Gross Income (AGI)

Adjusted gross income is defined as gross income minus adjustments to income. If your income (e.g., change in job) or personal circumstances (e.g., change in marital status) did not change from last year, we suggest you refer to your 2007 federal income tax return to get a quick estimate of your 2008 AGI. On your 2007 federal tax return, please refer to:

  • Line 4 if you filed a Form 1040EZ
  • Line 21 if you filed a Form 1040A
  • Line 37 if you filed a Form 1040

Important Reminder: If your filing status was single on your 2007 tax return and you plan to file a joint return for 2008, then add your spouse's 2007 AGI to yours when estimating your 2008 AGI.

For more details, see the Instructions for Form 1040 or you may want to refer to the Form 1040.
