Medicare costs are expected to rise again in 2026 — and for many seniors, that means less money in their Social Security check. Between premium increases, IRMAA surcharges, and higher deductibles, your healthcare expenses could take a bigger bite than last year.
That’s why understanding 2026 Medicare premiums and IRMAA before the enrollment season is essential. At Skyline Benefit, we help seniors stay ahead of the numbers, compare Advantage and Part D plans, and find smart ways to reduce out-of-pocket costs — all at no cost to you.
What is IRMAA (Income-Related Monthly Adjustment Amount)?
IRMAA is an additional monthly charge added to your standard Medicare Part B and Part D premiums if your income is above a certain threshold. Medicare calculates this surcharge each year using income brackets, so higher earners pay a larger share of their Medicare costs. The government determines your IRMAA based on your tax return from two years earlier.
How Much Will Medicare Part B Cost in 2026?
According to the Medicare Trustees’ latest report, the standard Part B premium is projected to rise 11.6% in 2026 — from $185.00 in 2025 to $206.50 next year.
- 2025 standard premium: $185.00
- 2026 projected premium: $206.50
- Dollar increase: $21.50/month
This would be the biggest Part B premium hike since 2022, and for most beneficiaries, the cost is automatically deducted from their monthly Social Security benefits.
What’s the Projected Part B Deductible for 2026?
The Part B annual deductible is expected to jump to $288.00 in 2026 — up from $257 in 2025. That’s an 11.2% increase, and it means you’ll pay more out-of-pocket before Medicare begins covering doctor visits, labs, and outpatient care.
What About Medicare Part D Premiums in 2026?
Part D premiums vary by plan, but the base beneficiary premium is projected to be $38.99 — compared to $34.70 in 2025. However, most enrollees pay less due to CMS’s premium stabilization rules.
Other projected changes:
- Annual deductible: Rising to $615 (up from $590 in 2025)
- Out-of-pocket cap: Increasing to $2,100, up from $2,000
After reaching this cap, your covered prescription costs drop to $0 for the rest of the year
2026 Medicare Premiums and IRMAA: Who Pays Extra?
If your income is above a certain threshold, you’ll owe a surcharge called IRMAA (Income-Related Monthly Adjustment Amount). This applies to both Part B and Part D.
Your 2026 IRMAA is based on your 2024 modified adjusted gross income (MAGI).
How Will the 2026 Medicare Premiums Affect Your Social Security Check?
In 2026, Social Security is expected to boost monthly benefits by about 2.6% to 2.7%, which adds roughly $54 to the average retiree’s check.
However, Medicare Part B premiums are also increasing by $21.50, and Social Security will automatically deduct that amount from your benefits. That means your real increase could drop to about $32.50 per month.
In short, even if you get a raise, Medicare could take nearly 40% of it before you notice the difference.
When Is the 2026 Medicare Enrollment Window?
Medicare Open Enrollment runs from October 15 to December 7, 2025. During this time, you can:
- Switch from Original Medicare to Advantage (Part C)
- Enroll in or change your Part D drug plan
- Drop or switch Medicare Advantage plans
