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% jump 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 speaks to current Part B enrollees and anyone within a year or two of enrolling. If your modified adjusted gross income sits comfortably below $109,000 (single) or $218,000 (joint), you pay the standard premium and nothing more. The surcharge structure below applies 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 increases, both consistent with historical patterns. The agency also noted that without its policy action on skin substitute reimbursement in the 2026 Physician Fee Schedule Final Rule, the Part B premium would have risen by roughly $11 more per month.

The Part B annual deductible climbed alongside the premium, reaching $283 in 2026, up $26 from $257. The deductible applies once per calendar year before Part B pays its 80% share of approved services.

For context, the broader Consumer Price Index rose 4.2% over the 12 months ending in May 2026, its highest annual reading since April 2023, while the Federal Reserve’s preferred core PCE measure climbed 3.3% over the 12 months ending in April 2026. Medicare’s 9.7% premium increase outpaces both of those benchmarks by a meaningful margin.

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. Critically, IRMAA is a cliff structure, not 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, smaller Part D surcharge applies at the same income tiers, starting at $14.50 a month in the first tier.

The Two-Year Lookback Most Enrollees Forget

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

That timing creates a delayed reckoning, because the events that push retirees into a surcharge tier are usually one-time: 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 see the surcharge appear in 2026, two years after the cash was moved.

The interaction with retirement account withdrawals runs deeper than most retirees expect. As Suze Orman has put it on her podcast, “The money that you take out from a traditional retirement account will count towards income and probably increase your Medicare B premiums.” The same withdrawal can also push more Social Security income into taxable territory, layering a second cost onto the conversion.

The Survivor Trap and the Limits of SSA-44

Two follow-on mechanics deserve attention. First, when one spouse dies, the survivor begins filing as single. The single brackets run roughly half the joint brackets, so a household whose income never changed can newly trigger IRMAA, or jump a tier, the year after a death. The bracket shifts even though the income holds steady.

Second, Form SSA-44 lets a beneficiary request an IRMAA recalculation when income drops because of a qualifying life-changing event: 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. SSA-44 does not unwind a voluntary income event. A Roth conversion or a home sale, however much it raises MAGI, will not qualify.

Implications of the 2026 Numbers

Three things follow from the 2026 figures worth keeping front of mind.

Your 2024 tax return, specifically line 11 plus line 2a, determines your 2026 IRMAA exposure. Because the brackets are cliffs, a household within roughly $10,000 of the next threshold faces asymmetric risk from any late-cycle 2026 income event: crossing by $1 costs the same as crossing by $10,000.

If a qualifying life event has cut your income, Form SSA-44 is how you request an IRMAA recalculation. Filing it with supporting documentation, such as a retirement letter, death certificate, divorce decree, or employer notice, can apply the recalculation to the current premium year rather than forcing a two-year wait.

Finally, if your combined income sits within roughly $10,000 of an IRMAA bracket, the two-year Medicare premium effect becomes a meaningful variable in any Roth conversion decision, stacking on top of the standard tax-bracket math. Quantifying that second-order cost before pulling the trigger is worth the effort.

Editor’s note: This update corrected all “percent” usages to the “%” symbol, added that the May 2026 CPI reading of 4.2% is the highest since April 2023 per the Bureau of Labor Statistics, explicitly described IRMAA’s cliff (non-graduated) bracket structure, and confirmed the 2026 Part B standard premium of $202.90 and $283 deductible against official CMS and RRB sources.
