The Centers for Medicare & Medicaid Services (CMS) announced the 2026 Medicare costs on November 14, 2025. The headline figure: the standard monthly Part B premium climbs to $202.90, an increase of $17.90 from the $185.00 of 2025 — the largest dollar jump since 2022 and the first time the standard premium has crossed the $200 line.

The annual Part B deductible also moves up, to $283 from $257 — a $26 increase. Together, the two changes will be felt in January’s Social Security deposit by the roughly italico66 million Americans/italico enrolled in Medicare, and they will weigh in particular on the budget of retirees who rely on Social Security as their primary income.

Here are all the new numbers in one place, what they mean in practice, and what to plan for in 2026.

The new Part B numbers, side by side

The change in the standard Part B premium is small in percentage terms — 9.7% — but it is the headline cost most Medicare beneficiaries see, because the premium is automatically deducted from the monthly Social Security benefit. Here is the year-on-year comparison, based on the official CMS fact sheet:

  • Standard monthly premium: $185.00 in 2025 → $202.90 in 2026 (+$17.90)
  • Annual deductible: $257 in 2025 → $283 in 2026 (+$26)
  • Immunosuppressive drug premium (post-kidney transplant coverage): $103.00 → $121.60

CMS attributes the increase mainly to projected price growth and assumed utilization increases. The agency also noted that without the changes finalized in the 2026 Physician Fee Schedule Final Rule — which is expected to cut Medicare spending on skin substitutes by about 90% — the premium increase would have been roughly $11 a month higher, taking the standard premium close to $214.

For context: the 2026 increase compares with a 2.8% cost-of-living adjustment (COLA) on Social Security benefits, which adds about $56 a month to the average retired-worker check. Net of the higher Part B premium, that leaves roughly $38 of net COLA in the average retiree’s pocket — a tighter margin than the headline COLA suggests.

Part B IRMAA: what high-income retirees will actually pay

About 8% of Medicare beneficiaries pay more than the standard premium because of an income-related surcharge known as IRMAA — Income-Related Monthly Adjustment Amount. IRMAA is based on the modified adjusted gross income (MAGI) reported two years earlier (so the 2026 surcharges look at 2024 tax returns).

For 2026, the income brackets for individual filers (and for joint filers, in parentheses) are the following. Total monthly Part B premium is the standard $202.90 plus the surcharge:

  • MAGI up to $109,000 ($218,000 joint) → no surcharge → $202.90/month
  • $109,001 to $137,000 ($218,001 to $274,000 joint) → +$81.20 → $284.10/month
  • $137,001 to $171,000 ($274,001 to $342,000 joint) → +$202.90 → $405.80/month
  • $171,001 to $205,000 ($342,001 to $410,000 joint) → +$324.60 → $527.50/month
  • $205,001 to $499,999 ($410,001 to $749,999 joint) → +$446.30 → $649.20/month
  • $500,000 and above ($750,000 joint) → +$487.00 → $689.90/month

That last bracket means a high-income retired couple can pay more than $8,200 a year per person in Medicare Part B premiums alone, before any drug coverage, supplemental policy, or out-of-pocket spending. The cliff between brackets is sharp: a single dollar of MAGI over a threshold can lift the monthly bill by more than $80, so taxpayers near a cutoff often manage withdrawals from retirement accounts carefully.

The same income brackets drive a separate Part D surcharge, ranging from $14.50 to $91.00 a month on top of the underlying drug-plan premium. Combined, a top-bracket beneficiary can end up paying close to $9,300 a year just in Medicare premiums.

Part A 2026: hospital deductible up to $1,736

Most beneficiaries — about 99% — do not pay a Part A premium because they earned at least 40 quarters of Medicare-covered employment. But Part A still has its own out-of-pocket structure, and those numbers also shift in 2026:

  • Inpatient hospital deductible (per benefit period): $1,676 in 2025 → $1,736 in 2026
  • Daily coinsurance, days 61–90: $419 → $434
  • Daily coinsurance, lifetime reserve days: $838 → $868
  • Skilled nursing facility coinsurance, days 21–100: $209.50 → $217.00

Beneficiaries who do not have 40 quarters of covered employment pay a Part A monthly premium that rises to $565 in 2026 (or $311 for those with at least 30 quarters). It is a relatively rare situation but it can apply to retirees with non-traditional or interrupted work histories — for example, those who spent most of their career in jobs not covered by Social Security.

What this means for your Social Security check

The new Part B premium is automatically withheld from the monthly Social Security benefit. For a retiree whose check went up by the full 2.8% COLA — average retired-worker benefit now around $2,071 a month — the deduction works out as follows:

  • Pre-COLA monthly benefit (2025): about $2,015
  • 2026 COLA bump (2.8%): +$56 → about $2,071
  • Part B deduction (2026): –$202.90 (vs. –$185.00 in 2025) → net deposit roughly $1,868

In other words, of the $56 monthly COLA increase, roughly $18 is absorbed by the higher Part B premium. The remaining $38 has to absorb everything else: rent inflation, grocery prices, energy bills, supplemental insurance premium hikes, and any rise in Part D drug-plan premiums above the inflation rate. For retirees in higher IRMAA brackets, the net change can easily be italiconegative/italico.

The hold-harmless rule: what protects most retirees

The federal “hold-harmless” provision prevents the dollar amount of the standard Part B premium increase from exceeding the dollar amount of a beneficiary’s Social Security COLA, for those whose Part B premium is paid out of their Social Security check. With the 2026 COLA of 2.8% and an average benefit comfortably above $1,000 a month, the average Social Security recipient is fully protected: the COLA more than covers the $17.90 premium increase.

The hold-harmless rule does italiconot/italico apply to several groups, including: new Medicare enrollees in 2026, retirees whose Part B premium is not deducted from a Social Security check, those subject to IRMAA, and dual-eligible beneficiaries whose premiums are paid by Medicaid. For these groups — roughly 30% of all Medicare beneficiaries — the full $202.90 applies regardless of COLA.

What to do this year

A few practical steps make the 2026 numbers easier to manage:

  1. Update your budget with the new monthly figure. If Medicare Part B is paid out of your Social Security check, your January deposit will be smaller than December’s by roughly $17.90 — even after the COLA. Knowing this in advance avoids the surprise.
  2. Verify your IRMAA bracket against your 2024 tax return. Because IRMAA is based on income from two years prior, taxpayers can request a redetermination using SSA Form SSA-44 if a major life event (retirement, marriage, divorce, death of a spouse, work stoppage) significantly reduced their income.
  3. Coordinate withdrawals across retirement accounts. With IRMAA brackets and rising premiums, the amount you draw from a 401(k) or Traditional IRA in any given year can change next year’s Medicare bill. A measured withdrawal mix — including from a Roth IRA, where the new 2026 contribution limits give more room — can keep MAGI below the next IRMAA threshold.
  4. Review your Part D and Medigap plans during open enrollment. Medicare Open Enrollment ran through December 7, 2025 for 2026 coverage. Beneficiaries who missed the window still have until March 31, 2026 to switch from Original Medicare to a Medicare Advantage plan, or vice versa, during the Medicare Advantage Open Enrollment Period.
  5. Plan for the gap. Out-of-pocket healthcare spending for a 65+ household averages around $7,000 a year, and that figure rises faster than headline inflation. For most retirees, the answer is a layered income strategy that combines Social Security, retirement-account withdrawals, and other sources of recurring cash flow.

The 2026 numbers are not a crisis. They are, however, a reminder that healthcare costs are a structural — not cyclical — pressure on the household budgets of older Americans. The same pressure has, over the last two decades, been quietly reshaping how millions of Americans plan for retirement in the first place: longer working years, larger private savings buffers, and a closer eye on the difference between gross retirement income and what actually lands in the bank account each month after Medicare and taxes.

For 2026, the bottom line is simple. The standard Part B premium is $202.90, the deductible is $283, and the IRMAA brackets remain unchanged from 2025. Build the new figures into your monthly cash-flow plan now, before the first deposit of the year hits.
