2027 IRMAA Brackets: Who Pays Extra for Medicare in Elizabeth

ELIZABETH, N.J. — As Medicare's Annual Enrollment Period runs from Oct. 15 through Dec. 7, many Union County retirees are opening letters from Social Security with a phrase that raises eyebrows: IRMAA, short for the Income-Related Monthly Adjustment Amount. It's the surcharge higher-income beneficiaries pay on top of their standard Part B and Part D premiums, and the income thresholds are set to shift again for 2027.

What's changing this fall for higher earners

If you're an Elizabeth resident whose income has climbed — because of a Roth conversion, the sale of a home, or a strong year of investment gains — this is the moment to understand how those numbers translate into your Medicare bill.

How IRMAA actually works

IRMAA isn't a separate bill. It's an add-on to your monthly Part B premium and, if you have drug coverage, your Part D premium. Social Security decides who owes it based on your modified adjusted gross income (MAGI) from two years earlier. So your 2027 IRMAA will be based on your 2025 tax return.

A few key points worth knowing:

• The surcharge applies to both Original Medicare enrollees and most Medicare Advantage members, because nearly all Advantage plans still include Part B.
• The Part D portion of IRMAA is paid directly to Medicare, even if your drug coverage is through a private plan.
• IRMAA is a "cliff" — go one dollar over a bracket and you pay the full higher amount for that tier.

The 2027 income brackets (single and joint filers)

For 2026, IRMAA surcharges kick in when a single filer's MAGI exceeds $109,000, or a married-filing-jointly MAGI exceeds $218,000. Above those points, there are five higher tiers, each with a larger surcharge, topping out for singles above roughly $500,000 and couples above roughly $750,000.

The exact monthly dollar amounts for each tier are set by CMS and published on Medicare.gov. Because the surcharge is layered on top of the standard Part B premium (which also adjusts each year), your total monthly cost depends on both.

If you'd like to see the current tier chart in one place, search "Medicare costs" at medicare.gov — CMS updates it as new figures are finalized.

What Elizabeth residents should watch for

Elizabeth is in Union County, where beneficiaries have access to Original Medicare plus a range of stand-alone Part D and Medicare Advantage options during AEP. IRMAA is the same nationwide — it doesn't change by ZIP code — but a few local realities matter:

• New Jersey's higher median incomes mean more households cross the first IRMAA threshold than in some other states.
• Union County has an active SHIP (State Health Insurance Assistance Program) counselor network through NJ Department of Human Services, offering free, unbiased help.
• If you're still working past 65 in Elizabeth and enrolled in Medicare, wage income can push you into IRMAA territory even if you don't feel "high income."

If your income has dropped, you can appeal

This is the part many people miss. If you had a life-changing event — retirement, the death of a spouse, divorce, loss of a pension, or reduced work hours — you can ask Social Security to recalculate IRMAA using your current income instead of a two-year-old return.

The form is SSA-44, available at ssa.gov. Bring documentation: a retirement letter, a death certificate, or pay records showing the change. Appeals are common and often successful when the paperwork is clear.

How IRMAA fits with the rest of 2027 Medicare

A few other figures are worth keeping in the same mental file:

• Part D out-of-pocket cap: $2,100 in 2026 and $2,400 in 2027 — a hard ceiling on what you pay for covered drugs.
• Part D maximum deductible: $615 in 2026 and $700 in 2027.
• The old coverage gap ("donut hole") is gone as of 2025; Part D now has three phases.
• The Medicare Prescription Payment Plan lets you spread drug costs into monthly installments at no extra charge.

IRMAA is separate from all of these — it's about premiums, not drug costs — but together they shape your total Medicare spending.
