2027 IRMAA Brackets: Medicare in Montgomery, AL

Montgomery, Alabama — If your income has climbed in recent years, your 2027 Medicare bill could look different than a neighbor's. Starting in January, higher-income beneficiaries will again pay an Income-Related Monthly Adjustment Amount, or IRMAA, on top of standard Part B and Part D premiums. With the Annual Enrollment Period running Oct. 15 through Dec. 7, now is the time to understand where the income lines fall — and what to do if you land just above one.

What IRMAA actually is

IRMAA is not a separate plan or penalty for late enrollment. It's a surcharge the Social Security Administration adds to your Part B and Part D premiums when your income is above a set threshold. Most people pay only the standard premium. A smaller group — generally higher earners — pays that standard amount plus an IRMAA amount tied to their income bracket.

Two important things to know up front:

• IRMAA is set each year using your modified adjusted gross income (MAGI) from your tax return two years earlier. For 2027, that means your 2025 tax return.
• The Part B surcharge is billed the same way your Part B premium is (usually deducted from Social Security). The Part D surcharge is billed separately by Medicare, even if you pay your drug plan's base premium to a private insurer.

The 2027 income thresholds

For 2026, IRMAA begins once a single filer's MAGI is above $109,000, or above $218,000 for a married couple filing jointly. Income at or below those amounts means you pay only the standard Part B and Part D premiums — no surcharge.

From there, the surcharge steps up through several income tiers. The highest tier applies to single filers with MAGI at or above roughly $500,000 (and married couples at or above roughly $750,000). Each step higher adds a larger dollar amount to both your Part B and your Part D premium. CMS publishes the exact dollar figures each fall at Medicare.gov.

A few quick notes on the brackets:

• Married filing separately has its own, much tighter thresholds — the surcharge can kick in at a far lower income.
• The tiers are cliffs, not phase-ins. One dollar over a threshold puts you into the next bracket for the whole year.

Why the two-year lookback matters

Because 2027 IRMAA is based on 2025 income, a one-time bump — selling a house, cashing out an IRA, taking a large capital gain — can push you into a surcharge bracket even if your current income is much lower.

If a life-changing event has reduced your income since 2024, you can ask Social Security to use more recent figures. Qualifying events include:

• Marriage, divorce, or the death of a spouse
• Work stoppage or reduced work hours (including retirement)
• Loss of income-producing property (not from a sale)
• Loss or reduction of a pension
• An employer settlement payment

The form is SSA-44, "Medicare Income-Related Monthly Adjustment Amount – Life-Changing Event." You file it with Social Security, along with documentation. If approved, they'll recalculate your surcharge.

How this fits with the rest of 2027 Medicare

Even if you pay IRMAA, the broader 2027 Medicare rules still apply to you:

• Part D out-of-pocket cap: $2,100 in 2026 and $2,400 in 2027 on 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 (deductible, initial coverage, catastrophic).
• Medicare Prescription Payment Plan: an optional program that lets you spread your out-of-pocket drug costs into monthly installments instead of paying at the pharmacy counter.

IRMAA does not change these figures. It changes what you pay in premiums, not what you pay at the pharmacy or the doctor's office.

What Montgomery residents can do this fall

Montgomery is in Montgomery County, where beneficiaries choose between Original Medicare (with or without a stand-alone Part D drug plan) and Medicare Advantage plans offered by private insurers. For 2027, the county has 67 Medicare Advantage plans from 8 carriers. You can see the current options and compare them using the Plan Finder at Medicare.gov.

If IRMAA affects you, a few practical steps during AEP (Oct. 15 – Dec. 7):

1. Check your 2025 tax return. Look at your MAGI and compare it to the 2027 thresholds once CMS publishes them later this fall. 2. Watch your mail. Social Security sends an IRMAA determination letter — usually in November or December — telling you what you'll owe. If you disagree, the letter explains how to appeal or file SSA-44. 3. Review your Part D or Medicare Advantage plan's Annual Notice of Change. Your plan's own premium, formulary, and pharmacy network can shift year to year, independent of IRMAA. 4. Talk to Alabama SHIP. The State Health Insurance Assistance Program offers free, unbiased Medicare counseling. In Alabama, it's run through the Department of Senior Services.
