What Is Modified Adjusted Gross Income (MAGI)?

An individual's Adjusted Gross Income (AGI) is referred to as Modified Adjusted Gross Income (MAGI) after subtracting specific deductions and tax penalties. It's crucial to comprehend it because it can reduce taxable income, particularly when considering retirement plan contributions.

Furthermore, MAGI is a major factor in determining eligibility for various benefits. These benefits include the Child Tax Credit, interest deductions on student loans, and income-based Medicaid coverage or health insurance subsidies.

MAGI is a more comprehensive financial calculation than gross income and adjusted gross income (AGI).

Gross income is the entire amount of money you get from all sources, including tips, investments, pension payments, and rental income.

After deducting specific items, gross income becomes adjusted gross income. However, it's important to note that this calculation does not consider standard or itemized deductions and exemptions.

The fact that multiple definitions of MAGI are applied for different tax benefits makes MAGI more complicated.

Although bringing back excluded foreign-earned income is typical of MAGI calculations, not all methods include adding back adoption benefits or excludable savings bond interest. 

Key Takeaways

  • Modified Adjusted Gross Income (MAGI) reduces taxable income and determines eligibility for various benefits and subsidies.
  • When calculating MAGI, some excluded income, such as foreign-earned income, is added to the adjusted gross income (AGI).
  • MAGI determines contributions to retirement plans, student loan interest deductions, the Child Tax Credit, and Medicaid/health insurance subsidies.

Understanding Modified Adjusted Gross Income (MAGI)

Modified Adjusted Gross Income (MAGI) refers to a household's AGI after certain amounts, such as interest income exempt from taxes and certain tax deductions, have been subtracted.

IRS uses MAGI to decide if you qualify for various tax-related perks. Here's a summary of its main applications:

  1. Roth IRA Eligibility: MAGI helps assess whether your income is above the range for contributing to a Roth Individual Retirement Account (IRA). Contributions to a Roth IRA come with tax benefits, especially when withdrawing funds in retirement.
  2. Traditional IRA Deductions: MAGI plays a major role in confirming eligibility for the contribution amount to the traditional IRA deduction. It determines your eligibility for a tax deduction on retirement plan contributions for you and your spouse with 401(k) plans.
  3. Premium Tax Credit: Modified Adjusted Gross Income (MAGI) is a key factor in determining the eligibility for the Premium Tax Credit. This credit may provide financial aid to individuals who purchase health insurance through State or Federal Health Insurance Marketplaces. Eligibility for this credit is primarily determined by comparing income to MAGI.

MAGI and Its Uses

Modified Adjusted Gross Income (MAGI) is a key financial metric influencing your taxable income and eligibility for various tax credits and deductions.

Certain credits and deductions have MAGI thresholds, and you may lose some or all of these benefits if your MAGI exceeds these limits.

Furthermore, MAGI is critical in determining your eligibility for healthcare waivers and incentives made available by the Affordable Care Act (ACA) through state health insurance marketplaces. It is also an important eligibility criterion for state Medicaid programs.

In essence, MAGI is a comprehensive measure that goes beyond taxable income to influence various aspects of your financial eligibility and benefits in the areas of taxation and healthcare.

The following are the traditional and Roth IRA income limits for 2023:

ROTH IRA

Your eligibility to contribute to a Roth IRA is also based on your MAGI. Unlike regular retirement funds that grow tax-deferred, Roth accounts are tax-exempt and funded using after-tax money.

If your MAGI exceeds the IRS-specified restrictions, you are not eligible to contribute to a Roth IRA.

If you meet the income requirement, the actual amount you can contribute is also based on your MAGI. If your MAGI is higher than permitted, your contributions are phased out.

Roth IRA income limits

Traditional IRA 

If you contribute more than the allowable amount, you will face a tax penalty unless you remove the excess contributions. The remaining balance in your IRA is taxed at a 6% annual rate.

Your married spouse's income and participation in employer-sponsored retirement plans determine whether you can deduct traditional IRA contributions from their income.

Up to the maximum amount of contributions, you are qualified for a full deduction if a workplace plan does not cover your spouse. However, if one partner has health insurance through their job, your deduction may be limited.

Calculation of MAGI (Modified Adjusted Gross Income)

The MAGI (Modified Adjusted Gross Income) is important in calculating and determining tax credits and deductions.

  • Step 1: Calculate Gross Income
  • Step 2: Calculate Adjusted Gross Income
  • Step 3: Calculate Modified Adjusted Gross Income

Step 1: Calculate Gross income

Your gross income (GI) is the most basic type of money you receive. It contains your entire income before any tax deductions are applied to the total.

There are numerous sources of your GI, such as taxable income received from:

  • Pay, gratuities, and income
  • Earnings
  • Royalties and rentals
  • Capital gains.
  • Profits from businesses
  • Agricultural revenue
  • Lack of Work
  • Alimony from divorce settlements obtained
  • Retirement income with interest

You can determine your GI (Gross Income) on line 7b on IRS Form 1040 instead of doing the math yourself. 

Step 2: Calculate Adjusted Gross Income

After calculating your gross income, the adjusted income by deducting allowable deductions to arrive at your adjusted gross income (AGI).

It determines whether you are eligible for certain tax credits, such as:

  • The credit for dependent care and children
  • Credits for people who are too old or too crippled to work
  • The credit for adoption
  • Children's Tax Credit
  • The tax credits for lifetime learning and American opportunity
  • The Credit for Earned Income

Modifications may consist of the following:

Contributions to IRAs and some business costs for contract government workers, reservists, and gig performers.

Contributions to a traditional IRA are permitted regardless of your household income. However, if you exceed the contribution limit and do not withdraw the excess funds, you will be subject to a 6% annual tax penalty until the surplus is withdrawn.

  • Health savings contribution Account (HSA) 
  • Health insurance Premium (for self-employed individuals)
  • Self-employment (50%)
  • Moving costs
  • Alimony awards
  • Education costs
  • Penalty for early withdrawals from savings
  • Deductions for tuition and fees
  • Interest deductions on student loans

AGI above a certain threshold bars you from deducting many things, including total itemized deductions, mortgage insurance premiums, and charitable contributions.

Your AGI can be found on line 11 of IRS form 1040, but your MAGI is not shown on your federal income tax return. To ensure you've completed the calculations accurately, you can work with a tax expert if you need assistance with the adjustments.

Step 3: Calculate Modified Adjusted Gross Income

You are now prepared to compute your Modified Adjusted Gross Income after determining your AGI.

As your income rises, the IRS phases out credits and allowable deductions. The IRS calculates your MAGI by deducting these items from your AGI to determine how much you made.

To calculate your MAGI, add the following to your AGI:

  • Interest deduction on student loans
  • Half of the taxes you pay on self-employment
  • Permissible educational costs, such as tuition and fee deductions
  • Inactive earnings or deficits
  • Losses from publicly traded partnerships or from rentals
  • IRA installments
  • Social Security benefits that are not taxable

Conclusion

When evaluating who is eligible for certain benefits, like the Child Tax Credit, student loan interest deductions, and health insurance subsidies, MAGI is a critical factor. It also significantly impacts retirement planning decisions, influencing traditional and Roth IRA contributions.

The influence of MAGI on qualifying for tax credits, deductions, and healthcare incentives draws attention to how important it is. The comprehensive 2023 Roth and traditional IRA income limits provide useful information for budgeting.

With the practical approach provided by the step-by-step guide to MAGI calculation, one can accurately calculate their Modified Adjusted Gross Income.

The importance of MAGI in helping make well-informed decisions regarding financial planning and tax liability is frequently emphasized.
