AGI vs MAGI on Your Taxes: What They Are, How to Calculate Them

In This Article

Understanding your income for taxes involves two key terms: AGI (Adjusted Gross Income) and MAGI (Modified Adjusted Gross Income). AGI is your total income minus deductions, while MAGI builds on AGI, adding certain deductions back and having an impact on tax liability and benefit eligibility.

For instance, IRA contributions depend on MAGI. To calculate, gather income information, subtract specific items for AGI, and then add back relevant deductions for MAGI.

1. AGI vs MAGI: What They Are

AGI (Adjusted Gross Income) is your total income minus specific deductions, such as IRA contributions and student loan interest on Form 1040. MAGI (Modified Adjusted Gross Income) is AGI plus certain deductions you add back, like tax-exempt interest and foreign income.

While AGI is directly on your tax return, you need to calculate MAGI for specific purposes. Both figures play a crucial role in determining taxable income and meeting various tax requirements.

In essence, Adjusted Gross Income (AGI) and Modified Adjusted Gross Income (MAGI) are distinct measures in taxation. AGI deducts certain expenses, while MAGI adds some back, influencing tax liability and eligibility for benefits.

For example, the deduction for traditional IRA contributions depends on MAGI, which includes AGI plus specific adjustments. MAGI thresholds include student loan interest deduction which varies based on your filing status. The Premium Tax Credit, aiding health insurance costs, relies on MAGI, including AGI and additional factors.

2. Differences Between AGI and MAGI

Adjusted Gross Income (AGI) and Modified Adjusted Gross Income (MAGI) are crucial metrics for tax calculations, influencing your tax liability and eligibility for various tax benefits. The key distinctions between AGI and MAGI are:

Composition of Income: AGI includes total income, including wages, interest, dividends, and capital gains. It deducts adjustments like IRA contributions, student loan interest, alimony payments, and half of the self-employment tax, while MAGI builds upon AGI, adding back specific deductions that you subtract initially. This includes items like the foreign earned income exclusion, tax-exempt interest, and certain deductions related to rental losses.

Determining Factors: AGI ascertains the federal income tax bracket, eligibility for tax credits (e.g., Child Tax Credit, Earned Income Tax Credit), and your ability to claim specific itemized deductions (e.g., medical expenses, miscellaneous itemized deductions), while MAGI evaluates your eligibility for particular tax deductions and benefits such as IRA contribution deductions, premium tax credit for health insurance, and income limits for Roth IRA contributions.

Calculation Reference: AGI is on line 11 of Form 1040 or 1040-SR, providing a straightforward measure of total income after adjustments, while MAGI requires reference to specific tax benefits or deduction instructions, as the calculation varies based on your particular situation.

3. Calculations and Comparisons for AGI and MAGI 

To calculate and compare AGI and MAGI, you need to:

  • Begin your tax reporting process with information gathering about your income from diverse sources, including wages, salaries, tips, dividends, interest, alimony, pensions, business income, and rental income. Use appropriate forms such as W-2, 1099, or Schedule C to report the amounts on your tax return.
  • Compute your Adjusted Gross Income (AGI), subtracting specific adjustments from your total income. These adjustments comprise contributions to IRAs, student loan interest, alimony payments, self-employment taxes, and other eligible items. Refer to Schedule 1 of Form 1040 or Form 1040-SR for a comprehensive list of adjustments.
  • Determine your Modified Adjusted Gross Income (MAGI), incorporating certain adjustments back into your AGI. The adjustments vary based on your purpose of calculating MAGI. Use a MAGI calculator or worksheet to facilitate this step, considering the specific adjustments applicable to your MAGI calculation purpose.
  • Compare your AGI and MAGI with income limits with various tax benefits, including credits, deductions, and exemptions. Consult the IRS website, relevant form instructions, or Publication 17 for these limits. Some tax benefits phase out gradually with increasing income, while others become entirely unavailable beyond certain thresholds. Thoroughly review the eligibility criteria for each tax benefit and make claims accordingly on your tax return.

Calculate AGI

Calculate AGI, totaling income from lines 1 to 8, then subtract the sum from line 22 of Schedule 1. This result is your AGI, you report on line 11 of Form 1040 or Form 1040-SR.

Your gross income is the total income you earn from various sources in a tax year before you apply any deductions or adjustments.

To calculate your total gross income, you add up all the amounts from lines 1 to 8 of Form 1040 or Form 1040-SR. This is the starting point to determine your taxable income and your tax liability.

For additional guidance and worksheets, consult the Form 1040 and Form 1040-SR instructions, or utilize online tools and software to assist with your tax return.

Calculate MAGI

You derive your Modified Adjusted Gross Income (MAGI) from your Adjusted Gross Income (AGI) when you add certain deductions or adjustments back in. To compute MAGI, you add back deductions relevant to the purpose of your calculation.

For instance, if determining MAGI for the IRA deduction, include additions like IRA contributions and student loan interest. Adjust your AGI accordingly, based on the specific deductions you require for your MAGI calculation.

Types of Adjustments

Common adjustments include:

IRA Deductions: MAGI determines your eligibility to deduct IRA contributions based on your income and coverage limits.

Student Loan Interest: MAGI determines your qualification for the student loan interest deduction based on income thresholds.

Tuition and Fees: MAGI determines eligibility for education credits like the American Opportunity Credit or the Lifetime Learning Credit.

Types of Income in Gross Income

Wages, Salaries, and Tips: This includes the compensation you receive for services you perform as an employee. Report these amounts on line 1 of Form 1040 or Form 1040-SR, referencing information from your Form W-2.

Interest: The money you earn for lending your money to entities such as banks, corporations, or the government. Report interest income on line 2 of Form 1040 or Form 1040-SR, using information from your Form 1099-INT or other relevant statements.

Dividends: Income you receive from owning shares in a corporation or mutual fund. Report dividends on line 3 of Form 1040 or Form 1040-SR, using information from your Form 1099-DIV or other statements.

Capital Gains: Gains or losses from selling or exchanging capital assets like stocks, bonds, real estate, or collectibles. Report this on line 7 of Form 1040 or Form 1040-SR, referencing your Schedule D and Form 8949.

Other Income: Income from sources that are not above, including alimony, pensions, business income, rental income, unemployment compensation, and gambling winnings. Report this on line 8 of Form 1040 or Form 1040-SR, using information from your Schedule 1 and other relevant forms or statements.

4. Tips to Compare Your AGI and MAGI

Identify Income Limits: Determine the income limit or phase-out range for the relevant tax item, using a web search tool, consulting instructions, or referring to publications with the applicable forms or schedules.

 

Calculate AGI: Compute your AGI, subtracting eligible adjustments from your gross income. Locate your AGI on line 11 of Form 1040 or Form 1040-SR.

 

Calculate MAGI: Calculate your MAGI, reintegrating specific adjustments into your AGI. Use a MAGI calculator or worksheet tailored to your MAGI calculation purpose.

 

Compare with Income Limits: Compare your AGI or MAGI with the income limit or phase-out range for the tax item. If your income falls below the limit or within the range, you may qualify for the tax benefit. If your income exceeds the limit or falls outside the range, you are not eligible, or your benefit reduces.

 

Determine Benefit Amount: Ascertain the deduction, credit, or benefit you can claim based on your income and other factors. Employ formulas, tables, worksheets, or software for precise calculations. For instance, the IRA deduction requires using Worksheet 1-1 to determine your deductible amount based on MAGI and filing status.

 

Use Interactive Tax Assistant: Utilize the Interactive Tax Assistant tool on the IRS website for further assistance. This tool addresses tax law questions specific to your circumstances. Input your information to receive responses unique to your situation, and explore topics through search features or categories on the tool’s page.   

Recap

AGI (Adjusted Gross Income) deducts expenses, while MAGI (Modified AGI) adds some back, impacting tax and benefit eligibility. AGI determines tax brackets and credits; MAGI influences deductions like IRA contributions and student loan interest.

To calculate, gather income sources, compute AGI (subtracting adjustments), and then calculate MAGI (adding back specific deductions). Compare with income limits for benefits and use IRS tools for clarity.
