What is Adjusted Gross Income?
Adjusted gross income (AGI) is a term found on
Form 1040.
It is an important number because it is used to limit certain
deductions.
For example, you can only deduct the portion of medical
expenses that exceed 7.5% of AGI for federal income tax
purposes. However, for state income tax purposes, this limitation may
not apply. For example, in Arizona you can deduct 100% of medical
expenses.
Adjusted gross income is figured on lines 7 through 37 on the from a Form 1040 and includes various items of income and deductions from income.
Above-the-Line Deductions
Deductions used to arrive at adjusted gross income are referred to as above-the-line deductions.
Above-the-line deductions are deductible even if you don't itemize.
For tax year 2011, the following are above-the-line deductions:
- Loss from business (Line 12)

Below-the-Line Deductions
Deductions that reduce adjusted gross income are referred to as below-the-line deductions.
For example, the standard deduction or itemized deductions and personal exemptions
are below-the-line deduction since they are not considered when figuring
AGI.
Adjusted Gross Income May Limit Certain Deductions
Federal tax rules use adjusted gross income to limit the amount that may be deducted for certain expenses.
For example:
- The medical expense deduction:
- You can only deduct the amount of medical expenses that exceed 7.5%
of adjusted gross income.
- For example, if your adjusted gross income was $40,000 you could only deduct medical expenses that exceed $3,000 (7.5% x $40,000)
- So, if your medical expenses were $3,500, only $500 would
provide a tax benefit.
- Casualty and theft losses:
- Miscellaneous itemized deductions:
- Certain miscellaneous expenses, such as employer travel travel and entertainment expenses, employee union and professional dues, work clothes expenses, investment expenses, and tax preparation expenses, must exceed 2% of adjusted gross income to get any tax benefit.
- Charitable contribution deduction:
- A charitable contribution deduction is limited to 50%, 30%, or 20%, depending on the nature of the organization you contribute to and the donated property involved.
