Calculate Your 2026 IRMAA

IRMAA stands for Income-Related Monthly Adjustment Amount. It's an additional premium that higher-income Medicare beneficiaries pay on top of their standard Part B and Part D premiums. Think of it as a "Medicare tax" based on your income from two years ago.

Medicare uses your tax return information from 2 years ago because that's the most recent complete tax data the IRS has available when they determine your premiums. For 2026 premiums, they'll look at your 2024 tax return. This gives the Social Security Administration time to process the data and set your rates accurately. However, if you've had a life-changing event (retirement, divorce, loss of income), you can file an appeal to have your IRMAA adjusted based on more recent circumstances.

Yes! If you've experienced a life-changing event such as retirement, job loss, divorce, or death of a spouse, you can file a "Medicare IRMAA Reconsideration Request" using form SSA-44. Green Insurance Agency can help you navigate this appeal process and potentially reduce your premiums if your current income is significantly lower than what the IRS reported from 2 years ago.

The standard Medicare Part B premium for 2026 hasn't been officially announced yet, but historical increases average 5-6% annually. If you're subject to IRMAA, you'll pay the standard premium PLUS an additional income-related amount. Part D premiums vary by plan, but IRMAA surcharges are added on top of whatever plan premium you choose. Use our calculator above to estimate your total costs based on your income level.

Your MAGI for IRMAA purposes is your Adjusted Gross Income (AGI) from your tax return, plus any tax-exempt interest income. This includes wages, self-employment income, pensions, Social Security benefits, investment income, rental income, IRA distributions, and capital gains. It does NOT include Roth IRA distributions or qualified HSA distributions. You'll find your AGI on line 11 of your Form 1040.

Yes, significantly more! Married individuals filing separately face the highest IRMAA surcharges, with thresholds starting at just $109,000 for 2026 (unless you lived apart from your spouse the entire year). If you're married and living together, it's almost always more advantageous to file jointly for Medicare IRMAA purposes. We can help you understand how your filing status impacts your Medicare costs.
