Medicare premiums in 2025 will be based on your modified adjusted gross income (MAGI) from two years prior—that is, your 2023 income. Understanding how this income is calculated is crucial for accurately predicting your Medicare costs. This article will detail the specific income types included and excluded, helping you determine your potential premium contribution.

Understanding Modified Adjusted Gross Income (MAGI)

Your MAGI is a slightly modified version of your adjusted gross income (AGI). The key difference lies in certain deductions and exclusions that are added back into your AGI to arrive at your MAGI. This calculation is significant because Medicare uses MAGI, not AGI, to determine your premium payments.

What's Included in MAGI:

• Wages and Salaries: Income from employment.
• Self-Employment Income: Profits from your own business.
• Interest and Dividends: Income from investments.
• Capital Gains: Profits from the sale of assets (stocks, bonds, real estate).
• Rental Income: Income from properties you rent out.
• Pension Income: Payments from retirement plans.
• Social Security Benefits (for some calculations): Although Social Security benefits themselves are generally not taxed, they can be included in MAGI calculations under certain circumstances, especially when determining the income-related monthly adjustment amount (IRMAA) for Medicare Part B and Part D premiums.

What's Generally Excluded from MAGI for Medicare Premium Calculations:

• Tax-Exempt Interest: Income from municipal bonds.
• Child Support Received: Payments received for child support.
• Most Welfare Benefits: Payments received from government assistance programs.
• Certain Deductions: Specific deductions (such as those for student loan interest) are added back into AGI to calculate MAGI. The precise deductions added back vary, so consulting the IRS guidelines or a tax professional is recommended.

Important Note: The exact inclusion or exclusion of certain income types can be complex and depends on specific circumstances. Consulting a tax professional or referring to official IRS publications is always recommended for accurate calculations.

How MAGI Impacts Your Medicare Premiums in 2025

Once your 2023 MAGI is determined, it’s used to calculate your Medicare Part B and Part D premiums for 2025. Higher MAGI generally translates to higher premiums. The Social Security Administration (SSA) publishes income brackets and corresponding premiums annually. You can find this information on the SSA website or through your Medicare Summary Notice.

Medicare Part B: This covers doctor visits, outpatient care, and some other services. The standard Part B premium for 2025 will be announced closer to the end of 2024, but it's likely to be influenced by MAGI brackets.

Medicare Part D: This covers prescription drugs. Similar to Part B, Part D premiums for 2025 will be based on your 2023 MAGI, with higher income leading to higher premiums. You’ll also pay an income-related monthly adjustment amount (IRMAA) if your income exceeds certain thresholds. This is separate from your standard Part D premium.

Determining Your 2025 Medicare Premiums: A Step-by-Step Guide

1. Gather your 2023 tax information: This includes your W-2 forms, 1099 forms, and any other documentation showing your income.
2. Calculate your 2023 Adjusted Gross Income (AGI): This is found on your 2023 tax return (Form 1040, line 8b).
3. Adjust for MAGI: Certain deductions might need to be added back into your AGI. Refer to IRS Publication 970, "Tax Guide to Modified Adjusted Gross Income," or consult a tax advisor.
4. Check the 2025 Medicare Premium Tables: Once you have your MAGI, refer to the official SSA tables to find the corresponding premiums for Part B and Part D. These tables will be released closer to the end of 2024.
5. Consider IRMAA: If your MAGI exceeds certain thresholds, you will pay an additional premium amount.
