What Is Modified Adjusted Gross Income (MAGI)?
It is an important number to understand since it can help reduce an individual's taxable income (to account for your retirement account contributions), factor in the eligibility for benefits like the student loan interest deduction and the Child Tax Credit, and establish eligibility for income-based Medicaid coverage or health insurance subsidies.
- Modified adjusted gross income (MAGI) is an important figure for understanding your taxable income.
- MAGI adjusts the adjusted gross income (AGI) for certain tax deductions and credits.
- You’ll have to crunch some numbers to find your MAGI, but tax preparation software makes this work easy.
- MAGI can change your eligibility for certain programs like qualified retirement account contributions as well as other programs.
Modified Adjusted Gross Income (MAGI)
Understanding Modified Adjusted Gross Income (MAGI)
Modified adjusted gross income can be defined as your household’s AGI after any tax-exempt interest income and after factoring in certain tax deductions. The Internal Revenue Service (IRS) uses MAGI to establish whether you qualify for certain tax benefits. MAGI notably determines:
- Whether your income does not exceed the level that qualifies you to contribute to a Roth individual retirement account (IRA)
- Whether you can deduct your traditional IRA contributions if you and/or your spouse have retirement plans, such as a 401(k) at work
- Whether you’re eligible for the premium tax credit, which lowers your health insurance costs if you buy a plan through a state or federal Health Insurance Marketplace
You can contribute to a traditional IRA no matter how much money you earn. You can typically deduct the IRA contribution amount, reducing your taxable income for that tax year. However, you can’t deduct contributions when you file your tax return if your MAGI exceeds limits set by the IRS and you and/or your spouse have a retirement plan at work.
MAGI and Its Uses
Your MAGI is an important figure, not only for understanding your taxable income, but also for qualifying for certain tax credits or deductions. Several such credits and deductions have thresholds that look at your MAGI and not your unadjusted gross income. MAGI's above those thresholds will see those credits or deductions phase-out or disappear.
MAGI is also used to determine eligibility for healthcare waivers and incentives under the Affordable Care Act (ACA) for states' health insurance marketplaces. It is also used as a threshold for qualifying for state Medicaid programs.
MAGI is also used to determine your eligibility to contribute to a Roth IRA. Roth accounts use after-tax dollars and grow tax-exempt (unlike traditional retirement accounts that are instead tax-deferred).
To contribute to a Roth IRA, your MAGI must be below the limits specified by the IRS. If you’re within the income threshold, the actual amount you can contribute is also determined by your MAGI. If your MAGI exceeds the allowed limits, then your contributions are phased out.
Here’s a rundown of Roth IRA income limits for 2022:
|2022 Roth IRA Income Limits|
|If your filing status is…||And your modified AGI is…||Then you can contribute…|
|Married filing jointly or qualifying widow(er)||Less than $204,000||Up to the limit|
|More than $204,000 but less than $214,000||A reduced amount|
|$214,000 or more||Zero|
|Single, head of household, or married filing separately and you didn’t live with your spouse at any time during the year||Less than $129,000||Up to the limit|
|More than $129,000 but less than $144,000||A reduced amount|
|$144,000 or more||Zero|
|Married filing separately and you lived with your spouse at any time during the year||Less than $10,000||A reduced amount|
|$10,000 or more||Zero|
If you contribute more than you’re allowed, you have to remove the excess contributions. Otherwise, you’ll face a tax penalty. Excess contributions are taxed at a rate of 6% per year for as long as the excess amount remains in your IRA.
Your MAGI and whether you and your spouse have retirement plans at work determine whether you can deduct traditional IRA contributions. If neither spouse is covered by a plan at work, then you can take the full deduction up to the amount of your contribution limit. However, if either spouse has a plan at work, then your deduction may be limited.
Here’s a rundown of traditional IRA income limits for 2022:
|2022 Traditional IRA Income Limits|
|If your filing status is…||And your modified AGI is…||Then you can take…|
|Single, head of household, qualifying widow(er), married filing jointly or separately and neither spouse is covered by a plan at work||Any amount||A full deduction up to the amount of your contribution limit|
|Married filing jointly or qualifying widow(er) and you’re covered by a plan at work||$109,000 or less||A full deduction up to the amount of your contribution limit|
|More than $109,000 but less than $129,000||A partial deduction|
|$129,000 or more||No deduction|
|Married filing jointly and your spouse is covered by a plan at work||$204,000 or less||A full deduction up to the amount of your contribution limit|
|More than $204,000 but less than $214,000||A partial deduction|
|$214,000 or more||No deduction|
|Single or head of household and you’re covered by a plan at work||$68,000 or less||A full deduction up to the amount of your contribution limit|
|More than $68,000 but less than $78,000||A partial deduction|
|$78,000 or more||No deduction|
|Married filing separately and either spouse is covered by a plan at work||Less than $10,000||A partial deduction|
|$10,000 or more||No deduction|
Tax laws are complicated and change periodically. If you need help figuring out your MAGI, or if you have any questions about IRA contribution and income limits, contact a trusted tax professional.
Many deductions are not commonly used, so your MAGI and AGI could be similar or even identical.
Calculating Your MAGI
Determining your MAGI is a three-step process:
- Figure out your gross income for the year.
- Calculate your AGI.
- Add back certain deductions to calculate your MAGI.
Figure Out Your Gross Income
Your gross income includes everything you earned during the year from:
- Alimony, which are court-ordered payments to a spouse due to divorce or separation
- Business income
- Capital gains or any realized gains after selling an asset for a profit
- Dividends, which are typically cash payments to a company’s shareholders
- Farm income
- Rental and royalty income
- Retirement income
There are two scenarios in which alimony payments are not considered gross income. The first is if your divorce agreement was executed after 2018. The second is if your divorce agreement was executed before 2019 but later modified to expressly state that such payments are not deductible for the payer.
Your gross income appears on line 9 of Form 1040.
Calculate Your AGI
Your AGI is important because it’s the total taxable income calculated before itemized or standard deductions, exemptions, and credits are taken into account. It dictates how you can use various tax credits and exemptions. For example, AGI affects the amount of money you can claim for the Child Tax Credit.
Your AGI is equal to your gross income, minus certain tax-deductible expenses, including:
- Certain business expenses for performing artists, reservists, and fee-basis government officials
- Educator expenses
- Half of any self-employment taxes
- Health insurance premiums (if you’re self-employed)
- Health Savings Account (HSA) contributions
- Moving expenses for members of the armed forces moving due to active duty
- Penalties on early withdrawal of savings
- Retirement plan contributions (including IRAs and self-employed retirement plan contributions)
- Student loan interest
You can do the math to figure out your AGI. Or you can find it on line 11 of Form 1040.
Add Back Certain Deductions
To find your MAGI, take your AGI and add back:
- Any deductions you took for IRA contributions and taxable Social Security payments
- Deductions you took for student loan interest
- Tuition and fees deduction
- Half of self-employment tax
- Excluded foreign income
- Interest from EE savings bonds used to pay for higher education expenses
- Losses from a partnership
- Passive income or loss
- Rental losses
- The exclusion for adoption expenses
How Do I Calculate Modified Adjusted Gross Income?
Calculating your MAGI is relatively straightforward. To do so, calculate your adjusted gross income (AGI) and then add back any of the deductions specified by the Internal Revenue Service that apply to your situation. Examples of these deductions include income from foreign sources, interest from certain savings bonds, and expenses related to adopting a child. Because MAGI involves adding back these deductions, MAGI will always be greater than or equal to AGI. To calculate your MAGI:
- Add up your gross income from all sources.
- Check the list of “adjustments” to your gross income and subtract those for which you qualify from your gross income. The list is on the 1040 form under Schedule 1.
- The resulting number is your AGI.
- Add back any deductions for which you qualify; these can include student loan interest and individual retirement account contributions.
- The resulting number is your MAGI.
What Purpose Does MAGI Serve?
The IRS uses MAGI to determine whether you qualify for certain tax programs and benefits. For instance, it helps to determine the allowed amount of your Roth IRA contributions. Knowing your MAGI can also help you avoid facing tax penalties because over-contributing to these programs and others like them can trigger interest payments and fines. Your MAGI can also determine eligibility for certain government programs, such as the subsidized insurance plans available on the Health Insurance Marketplace.
What Is the Difference Between MAGI and AGI?
You modified adjusted gross income (MAGI) is your adjusted gross income (AGI) plus additional items such as student loan interest, qualified education expenses, passive income or losses, IRA contributions, and foreign income, among others.
Can MAGI and AGI Be the Same?
Yes, MAGI and AGI can be the same. For many people, the list of deductions that need to be added back to AGI to calculate MAGI will not be relevant. For instance, those who did not earn any foreign income would have no reason to use that deduction and would have none of those earnings to add back to their AGI.
The Bottom Line
Modified adjusted gross income (MAGI) is an important figure for your tax returns to determine what you owe the IRS. It takes your gross income and adjusts and modifies it for certain exemptions, qualifications, and allowances. Your MAGI will differ from your adjusted gross income (AGI) if you have foreign income, qualified education expenses, or passive losses, among other items.
