Introduction
Your Modified Adjusted Gross Income (MAGI) is one of the most important numbers on your tax return. The IRS uses it to decide if you qualify for tax breaks like Roth IRA contributions, traditional IRA deductions, and education credits. MAGI starts with your Adjusted Gross Income (AGI) and adds back certain deductions and exclusions, such as foreign earned income, student loan interest, and IRA contributions. Many people assume their AGI and MAGI are the same, but even one add-back can change your number and affect your eligibility.
This free MAGI calculator makes it simple to find your Modified Adjusted Gross Income in seconds. Just enter your AGI and any add-back items, choose your filing status, and the tool does the math for you. It also shows a clear breakdown of each item, a visual chart, and checks your MAGI against key 2024 IRS income thresholds so you can see where you stand.

What Is Modified Adjusted Gross Income (MAGI)?
Modified Adjusted Gross Income, or MAGI, is a number the IRS uses to decide if you qualify for certain tax benefits. It starts with your Adjusted Gross Income (AGI), which is your total income minus specific deductions like student loan interest or IRA contributions. Then, some of those deductions get added back in. The result is your MAGI.
Your AGI is found on line 11 of your federal tax return (Form 1040). MAGI takes that number and adds back items such as foreign earned income exclusions, non-taxable Social Security benefits, student loan interest deductions, and IRA contribution deductions. Not every person has these add-backs. If you don't, your MAGI and AGI will be the same number.
Why Does MAGI Matter?
The IRS uses your MAGI to determine if you can contribute to a Roth IRA, deduct traditional IRA contributions, or qualify for premium tax credits on health insurance. Medicare also uses MAGI to decide if you pay extra for Part B and Part D coverage. If your MAGI is too high, you may lose access to these benefits or pay higher costs. Understanding where your income falls relative to tax brackets is also essential for overall tax planning.
MAGI Thresholds for 2024
Each tax benefit has its own income limits, and these limits change based on your filing status. For example, in 2024, single filers start to lose Roth IRA eligibility at $146,000 and are fully phased out at $161,000. Married couples filing jointly phase out between $230,000 and $240,000. Traditional IRA deduction limits and Medicare surcharge thresholds also depend on your MAGI and filing status. If you earn investment income, be aware that capital gains taxes can also be affected by your overall income level.
How to Lower Your MAGI
You can reduce your MAGI by contributing to a workplace retirement plan like a 401(k), putting money into a Health Savings Account (HSA), or increasing deductions that are not added back into the MAGI calculation. Our 401k Calculator can help you see how increasing your contributions affects your retirement savings, and our HSA Calculator can show the tax advantages of maximizing your health savings contributions. Lowering your MAGI can help you stay within the income limits for tax benefits you want to keep.
