Medicare IRMAA for 2026 will raise costs for higher‑income Medicare beneficiaries, with surcharges starting when 2024 income goes above roughly $109,000 (single) or $218,000 (married filing jointly). These income-related monthly adjustment amounts apply on top of the standard Part B premium and any Part D premium you owe.

What IRMAA Is in 2026

IRMAA is an extra charge added to Medicare Part B and Part D premiums when your modified adjusted gross income (MAGI) from two years prior crosses certain thresholds. For 2026, that means your 2024 federal tax return is what determines whether you pay IRMAA and how much.

  • IRMAA affects:
    • Medicare Part B (medical insurance) premiums.
* Medicare Part D (drug coverage) premiums, including stand‑alone plans and many Medicare Advantage plans with drug coverage.
  • Social Security notifies you by letter in late 2025 if an IRMAA will apply for 2026, showing which income bracket you’re in and the new monthly amount.

2026 Standard Premiums and IRMAA Ranges

The standard Part B premium and the typical Part D base premium both increase in 2026, and IRMAA adds a tiered surcharge on top.

  • Part B:
    • Standard premium: about $202.90 per month in 2026.
* IRMAA surcharge range: roughly **$81.20 to $487.00** extra per month depending on income.

* Total Part B premium for higher‑income enrollees: around **$284.10 up to about $689.90** per month.
  • Part D:
    • Average base (stand‑alone) premium: about $46.50 per month.
* IRMAA surcharge range: about **$14.50 to $91.00** extra per month.

These surcharges rise in steps across several income brackets and were reported to have increased by roughly 3% for brackets and about 9% for surcharge dollar amounts versus the prior year.

2026 IRMAA Income Thresholds

IRMAA is bracketed: once your MAGI crosses a threshold, you move into a higher premium band. For 2026, multiple independent Medicare/finance sources report the following lower thresholds for owing IRMAA.

Key starting thresholds

  • First IRMAA tier begins when:
    • Single filers / married filing separately: income above about $109,000.
* **Married filing jointly:** income above about **$218,000**.
  • Below or at those amounts, you pay only the standard Part B premium and no IRMAA on Part D.

Higher tiers step up from there and extend into very high incomes (for example, individual incomes up to and above $500,000 and joint incomes up to and above $750,000), with the top bracket currently frozen until at least 2028.

How the look‑back works

  • Year used: 2024 MAGI determines 2026 IRMAA.
  • Your MAGI includes:
    • Adjusted gross income plus certain add‑backs (like tax‑exempt interest).
  • If your income changes later (for example, retirement, divorce, death of a spouse), you may qualify to ask Social Security to reduce or remove IRMAA via an appeal.

Practical Impact and Planning Ideas

Rising IRMAA in 2026 makes income planning around Medicare more important for many near‑retirees and retirees. Even one‑time events—like selling a home, large Roth conversions, big capital gains, or cashing in large IRAs—can trigger a one‑year spike in premiums two years later.

Common strategies discussed by retirement and Medicare planners include:

  • Managing taxable income across years:
    • Spreading Roth conversions over several years to avoid jumping a bracket.
* Coordinating when you realize big capital gains (such as property or stock sales).
  • Using tax‑advantaged accounts and deductions:
    • Qualified charitable distributions (QCDs) from IRAs after age 70½ to reduce taxable IRA income.
* Maximizing HSA contributions and other tax‑favored savings while working, so less taxable income is needed later.
  • Appealing IRMAA when life events sharply cut income:
    • Retirement or reduced work.
    • Divorce, death of a spouse, or loss of a pension.

Because IRMAA brackets are indexed annually (except the top bracket, which is temporarily frozen), many people slowly drift into surcharges as their retirement income and inflation‑adjusted thresholds move.
