How AGI is calculated
Start with total income and subtract allowable adjustments to income. The IRS lists these adjustments in Part II of Schedule 1 (Form 1040).
AGI, taxable income and MAGI
AGI is not the same as taxable income or take-home pay. Modified adjusted gross income (MAGI) also differs from AGI, and its definition depends on the tax provision being applied.
Keep the supporting records
Keep those records available when preparing a return. Eligibility depends on the applicable rules; an expense is not automatically an allowable adjustment.
US federal tax reference
See the IRS definition of adjusted gross income. This entry explains the term and does not calculate a tax liability.
