Modified Adjusted Gross Income (MAGI) is used to determine eligibility for premium tax credits and other savings for Marketplace health insurance plans and for Medicaid and the Children's Health Insurance Program (CHIP). For many people, it’s identical to or very close to adjusted gross income.

Modified adjusted gross income is adjusted gross income plus these 3 kinds of income, if any:

• Untaxed foreign income
• Non-taxable Social Security benefits
• Tax exempt interest

MAGI includes these income sources for all household members required to file a tax return.

MAGI does not include Supplemental Security Income (SSI). Supplemental Security Income (SSI) is a monthly benefit paid by Social Security to people with limited income and resources who are disabled, blind, or 65 or older. SSI benefits aren't the same as Social Security retirement or disability benefits.

MAGI does not appear as a line on your tax return.

 

What to include as income

 

When you fill out a Marketplace application, you’ll need to estimate what your household income is likely to be for the current calendar year.

• In most cases you’ll use your gross income — your total income before taxes and other deductions are taken out. But see details in the chart below to be sure.
• Marketplace savings are based on your expected household income for 2021, not last year’s income. You must make your best estimate so you qualify for the right amount of savings.
• You may have the option to enter your income as monthly or yearly. You may be asked to confirm a yearly amount if we got the information somewhere else.

Whose income to include in your estimate

For most people, a household consists of the tax filer, their spouse if they have one, and their tax dependents, including those who don’t need coverage.

The Marketplace counts estimated income of all household members who are required to file a tax return.

What income is counted

The Marketplace uses an income number called modified adjusted gross income (MAGI) to determine eligibility for savings. It’s not a line on your tax return.

The chart below shows common types of income and whether they count as part of MAGI. If you expect income types not shown or have additional questions, see details on what the IRS counts as income.

Types of income to include in your estimate

Report income changes to the Marketplace

Once you have Marketplace health insurance, it’s very important to report any income changes as soon as possible.

If you don’t report these changes, you could miss out on savings or wind up having to pay money back when you file your federal tax return for the year.
