How to Appeal IRMAA After Retirement in 2026 and Lower Your Medicare Costs

Retired, but still paying an income-related Medicare surcharge? You may be able to ask Social Security to use more recent income after you or your spouse stops working or reduces work. This is not an automatic reduction, and it does not require changing Medicare plans.

People often call this an “IRMAA appeal.” For a qualifying retirement-related income drop, the usual starting point is a new initial determination, commonly requested with Form SSA-44. A formal appeal is a separate process.

Why can Medicare premiums stay high after retirement?

For 2026, Social Security generally starts with your 2024 tax return, or 2023 if 2024 information was unavailable. Your old working income may therefore affect the premium even after you retire. Medicare IRMAA uses modified adjusted gross income (MAGI): adjusted gross income plus tax-exempt interest, not simply your salary or taxable income.

California residents use the same federal IRMAA rules as other U.S. residents. Retirement can qualify as work stoppage; working fewer hours can qualify as work reduction. Social Security needs the event and the relevant income information to decide whether a lower adjustment applies. See the official SSA-44 instructions.

A hypothetical 2026 savings example

Suppose one person has both Part B and Part D and Social Security approves a move from the first IRMAA tier to the standard tier:

• Part B changes from $284.10 to $202.90 per month: an $81.20 difference.
• The $14.50 monthly Part D adjustment is removed. The drug plan’s own premium remains separate.
• The combined difference is $95.70 per month, or $1,148.40 for 12 months if the reduction applies throughout the year.

This calculation uses CMS’s published 2026 Part B rates and the SSA-44 adjustment table. It is an illustration, not a client result or a promise of approval, timing, or a refund. For joint filers, the income threshold is household-based, but IRMAA is charged per person.

Prepare for a retirement-related SSA-44 request

1. Check your notice. Identify the premium year, income year, filing status, and adjustment being charged. Keep the notice and any deadlines.
2. Identify the event. On SSA-44, retirement generally falls under “Work Stoppage”; reduced work may fall under “Work Reduction.” There is no separate “Retirement” checkbox.
3. Prepare income information. Follow the form’s instructions for the correct year. Ask your tax professional to help estimate full-year MAGI, including income other than wages.
4. Gather evidence. The form explains acceptable proof of work changes and income. Ask Social Security what it needs for your circumstances.
5. Submit through Social Security. Use the official online request, mail, fax, or appointment options. Keep a copy and follow up with SSA if further information is requested.

Do not upload tax returns, Social Security numbers, or Medicare numbers to Skyline’s general contact form. Submit sensitive evidence directly through Social Security’s official channels.

SSA-44 request or formal appeal?

A new initial determination asks SSA to consider qualifying new information. If you disagree with its determination, follow the notice’s reconsideration instructions. The appeal deadline is generally 60 days after receiving the determination notice. Do not assume an SSA-44 request automatically preserves appeal rights. Read SSA’s IRMAA appeal guidance and Form SSA-561 information.

If the issue is an amended return or incorrect tax information, contact SSA about the appropriate process. A voluntary property sale or Roth conversion is not itself an SSA-44 qualifying life-changing event. The agency’s new-determination guidance explains why these paths differ.

Retirement and IRMAA questions

Do I have to wait until I file another tax return?

Not always. SSA-44 allows estimated income in specified circumstances, including anticipated reductions. Follow its instructions and update SSA when your estimate changes or your return is filed.

Does my spouse need a separate request?

Yes. A new determination for one spouse is not automatically applied to the other. Each spouse seeking a change must contact SSA.

Will switching Medicare plans remove IRMAA?

No. IRMAA is a federal income-related adjustment. A different plan may change other costs or coverage, but does not itself remove IRMAA.

How long does approval take, and will I get a refund?

There is no guaranteed timeline or refund. SSA decides your request and any effective date or billing correction. Follow your notice and continue paying required premiums while the matter is reviewed.
