Medicare Part B Just Crossed $200 a Month, Here’s What It Means for Retirees

The standard Medicare Part B premium crossed a new threshold in January: beneficiaries with income below the first surcharge tier now pay $202.90 a month, up $17.90 from $185.00 in 2025. That 9.7% increase means a household where both spouses enroll now pays more than $4,800 a year in standard premiums alone, and Social Security deducts that amount from the couple’s checks before any money reaches them.

This article addresses current Part B enrollees and anyone within a year or two of enrollment. If your modified adjusted gross income sits comfortably below $109,000 (single) or $218,000 (joint), you pay the standard premium and nothing beyond it. The surcharge tiers described below apply only to the roughly 8% of Part B enrollees who exceed those thresholds.

What Drove the Increase

CMS attributes the 2026 increase to projected price changes and assumed utilization growth, both in line with historical patterns. The agency noted that its policy action on skin substitute reimbursement in the 2026 Physician Fee Schedule Final Rule held the premium down considerably: without that intervention, the Part B premium would have climbed by roughly $11 more per month, with spending on skin substitutes expected to fall 90% as a result of the rule change.

The Part B annual deductible rose alongside the premium, reaching $283 in 2026, up $26 from $257 the prior year. The deductible must be satisfied once per calendar year before Part B covers its standard 80% share of approved services.

For context, the Consumer Price Index rose 4.2% over the 12 months ending in May 2026, and has since cooled to 3.4% through August 2026 per the Bureau of Labor Statistics. The Federal Reserve’s preferred core PCE measure held at 3.3% over the 12 months ending in July 2026. Medicare’s 9.7% premium increase outpaces all of those benchmarks by a substantial margin.

Looking ahead, the 2026 Medicare Trustees Report projects the standard Part B premium will rise to approximately $209.50 a month in 2027, a 3.25% increase from 2026. That projection carries the usual caveats: CMS confirms the official figure each November, and the Trustees have underestimated actual premiums in recent years. Private forecasters generally expect the real 2027 number to land somewhere between $215 and $219.

The IRMAA Tiers Above the Standard Premium

For higher-income enrollees, the Income-Related Monthly Adjustment Amount stacks on top of the standard premium. The 2026 brackets for full Part B coverage, drawn from CMS, are as follows:

Every figure in the surcharge and total columns is per person, per month, for full Part B coverage. IRMAA operates as a cliff structure rather than a graduated scale: crossing a bracket threshold by a single dollar triggers the full surcharge for that entire tier, with no blending between brackets. When both spouses land in the first surcharge tier, each pays an extra $81.20 a month, adding roughly $1,950 a year above the standard household premium. At the top tier, a two-person household pays close to $16,560 a year for Part B alone. A separate Part D surcharge applies at the same income thresholds, starting at $14.50 a month in the first tier and reaching $91.00 a month at the top tier.

The Two-Year Lookback Most Enrollees Forget

IRMAA uses a two-year income lookback. The 2026 Part B premium is based on the modified adjusted gross income reported on the 2024 tax return. For this purpose, MAGI is adjusted gross income from Form 1040 line 11 plus tax-exempt interest from line 2a, which means municipal bond income that feels tax-free to the recipient still counts toward the bracket threshold.

That timing gap creates a delayed reckoning, because the events that push retirees into a surcharge tier tend to be one-time occurrences: a Roth conversion, a home sale, a large required minimum distribution, or a severance payment. A retiree who converted $100,000 from a traditional IRA in 2024 may find the surcharge appearing on the 2026 bill, two full years after the cash moved.

The interaction with retirement account withdrawals runs deeper than most retirees anticipate. Finance commentator Suze Orman has noted on her podcast that withdrawals from a traditional retirement account count toward income and can raise Part B premiums. Those same withdrawals can simultaneously push a greater share of Social Security benefits into taxable income, layering a second cost on top of the conversion.

The Survivor Trap and the Limits of SSA-44

Two additional mechanics carry real consequences. First, when one spouse dies, the survivor files as single. Single IRMAA brackets run roughly half the joint brackets, so a household whose income has not changed can newly trigger a surcharge, or jump a tier, the year after a death. The premium rises even though the household’s income held steady.

Second, Form SSA-44 allows a beneficiary to request an IRMAA recalculation when income has fallen because of a qualifying life-changing event. The eligible triggers are: marriage, divorce or annulment, death of a spouse, work stoppage, work reduction, loss of income-producing property, loss of pension income, or an employer settlement. The form does not apply to voluntary income events. A Roth conversion or home sale, however large, will not qualify for a recalculation regardless of its effect on MAGI.

Implications of the 2026 Numbers

Three practical points follow from the 2026 figures.

Your 2024 tax return, specifically line 11 plus line 2a, is the document that determines your 2026 IRMAA exposure. Because the brackets are cliffs, a household sitting within roughly $10,000 of the next threshold faces outsized risk from any income event in the final months of a tax year: the surcharge cost of crossing by $1 is identical to the cost of crossing by $10,000.

If a qualifying life event has reduced your income, Form SSA-44 is the mechanism for requesting an IRMAA recalculation. Filing with the right supporting documents, such as a retirement letter, death certificate, divorce decree, or employer notice, can apply the revised determination to the current premium year rather than requiring a two-year wait under the standard lookback.

Finally, for households near an IRMAA bracket, the two-year Medicare premium effect becomes a meaningful variable in any Roth conversion plan. That second-order cost stacks on top of the standard income-tax math, and calculating it explicitly before acting is worth the time.

Editor’s note: This update refreshed the inflation benchmarks to include the August 2026 CPI reading of 3.4% and the July 2026 core PCE reading of 3.3% per the Bureau of Labor Statistics and Bureau of Economic Analysis, added the upper end of the 2026 Part D IRMAA range ($91.00 per month at the top tier per the Railroad Retirement Board), and incorporated the 2026 Medicare Trustees Report projection of approximately $209.50 for the 2027 standard Part B premium.
