For millions of retirees, Medicare is one of the most important safety nets in retirement. But for higher-income seniors, there’s an extra cost that often comes as an unpleasant surprise: IRMAA. In 2025, some retirees could face up to $14,000 in additional Medicare costs due to this surcharge.
Here’s everything you need to know about what IRMAA is, who pays it, and how much it could affect your budget this year.
What Is IRMAA?
IRMAA stands for Income-Related Monthly Adjustment Amount. It’s an extra charge that higher-income Medicare beneficiaries must pay on top of their standard Medicare Part B (medical coverage) and Part D (prescription drug coverage) premiums.
The idea is simple: those with higher incomes contribute more toward Medicare’s cost. But for retirees living on fixed incomes, this can feel like a heavy financial burden.
Standard Medicare Premiums vs. IRMAA Costs
- The standard Medicare Part B premium in 2025 is expected to be around $179 per month (final amounts will be confirmed later this year).
- The standard Medicare Part D premium varies depending on the plan but averages about $35–$40 per month.
If your income is above certain thresholds, IRMAA is added to both Part B and Part D, meaning your monthly Medicare costs could more than double. Over a full year, this can add up to as much as $14,000 in extra costs.
Medicare Premiums With and Without IRMAA in 2025
Here’s a quick look at how much retirees may pay depending on income levels in 2025.
| Income (Single / Joint) | Part B Premium (Monthly) | Extra Part D IRMAA (Monthly) | Total Annual Cost (Approx.) |
|---|---|---|---|
| Up to $103,000 / $206,000 | $179 (standard) | None | ~$2,148 |
| $103,001 – $129,000 / $206,001 – $258,000 | $251 | +$13 | ~$3,168 |
| $129,001 – $161,000 / $258,001 – $322,000 | $323 | +$33 | ~$4,272 |
| $161,001 – $193,000 / $322,001 – $386,000 | $395 | +$53 | ~$5,364 |
| $193,001 – $500,000 / $386,001 – $750,000 | $467 | +$68 | ~$6,432 |
| Above $500,000 / $750,000 | $540 | +$81 | Over $14,000 |
Who Pays IRMAA in 2025?
The Social Security Administration (SSA) determines IRMAA based on your Modified Adjusted Gross Income (MAGI) from two years prior (so for 2025, your 2023 tax return is used).
Here are the 2025 income brackets that determine IRMAA charges:
- Individuals earning $103,000 or less (or couples $206,000 or less): Pay only the standard premiums, no IRMAA.
- Above $103,000 (individual) or $206,000 (joint): IRMAA charges begin.
The higher your income, the higher your surcharge.
2025 IRMAA Brackets (Estimated)
Medicare Part B Premiums With IRMAA:
- Income ≤ $103,000 (individual) / $206,000 (joint): Standard premium (~$179/month).
- $103,001 – $129,000 (individual) / $206,001 – $258,000 (joint): Around $251/month.
- $129,001 – $161,000 / $258,001 – $322,000: Around $323/month.
- $161,001 – $193,000 / $322,001 – $386,000: Around $395/month.

Medicare Part D Premiums With IRMAA:
- Additional $13 to $81 per month, depending on income level.
When you combine both Part B and Part D IRMAA charges, the highest-income retirees can pay more than $14,000 annually.
How IRMAA Is Collected
- If you receive Social Security benefits, IRMAA is usually deducted automatically from your monthly payment.
- If you are not yet taking Social Security, you’ll get a bill for the adjusted Medicare premium.
Can You Appeal IRMAA?
Yes. If your income has recently dropped due to certain life events, you may be able to request a reduction in your IRMAA charges. Accepted events include:
- Retirement or work reduction
- Marriage or divorce
- Death of a spouse
- Loss of income from property
You can file an appeal using Form SSA-44 (Medicare IRMAA Life-Changing Event form).
Why It Matters in 2025
The rise in IRMAA costs comes at a time when many retirees are already facing higher living expenses due to inflation and healthcare costs. While Medicare provides essential coverage, wealthier retirees should budget carefully for these surcharges.
For some, IRMAA could mean paying two to three times the standard Medicare cost, significantly impacting retirement planning.
