A retired teacher in her late 60s stops working in June, watches her income drop by half, and then opens her first Medicare bill to find a monthly premium hundreds of dollars above the standard rate. The surcharge is based on her tax return from two years earlier, when she was still earning a full salary. She pays it, assuming nothing can be done.
She would be wrong. The Social Security Administration allows Medicare beneficiaries to request a lower premium after specific life changes, and when the numbers support it, the agency issues refunds. The process costs nothing, requires one form, and is written directly into federal regulation. Yet the overwhelming majority of people who qualify never file. As of June 2026, free help is available through every state’s State Health Insurance Assistance Program (SHIP), and the form itself can now be submitted online.
How the IRMAA surcharge works
Medicare’s income-related monthly adjustment amount, known as IRMAA, is an extra charge added to Part B and Part D premiums for beneficiaries whose modified adjusted gross income (MAGI) exceeds certain thresholds. The Social Security Administration determines the surcharge using IRS tax data from two years prior. For 2026 premiums, SSA looks at 2024 tax returns.
The standard Part B premium for 2026 is $202.90 per month, according to the CMS fact sheet. Beneficiaries whose 2024 MAGI exceeded $106,000 as an individual or $212,000 as a married couple filing jointly pay more. Here is how the surcharges stack up across the five IRMAA tiers for Part B alone:
- Tier 1 (individual MAGI $106,001–$133,000): approximately $284 per month, adding about $975 per year over the standard premium.
- Tier 2 (individual MAGI $133,001–$167,000): approximately $406 per month, adding roughly $2,437 per year.
- Tier 3 (individual MAGI $167,001–$200,000): approximately $527 per month, adding roughly $3,889 per year.
- Tier 4 (individual MAGI $200,001–$500,000): approximately $527 per month at the same level as Tier 3 under the 2026 schedule.
- Tier 5 (individual MAGI above $500,000): approximately $594 per month, adding roughly $4,693 per year.
Part D carries its own separate IRMAA surcharges on top of whatever drug plan premium a beneficiary already pays. For a married couple where both spouses are enrolled and surcharged, the combined annual hit doubles. A couple in the second bracket could face more than $4,800 in additional Part B premiums per year before Part D surcharges are counted.
The life changes that qualify for a reduction
Federal regulation (20 CFR § 418.1205) lists the specific events that allow a beneficiary to ask SSA to use a more recent year’s income instead of the two-year-old tax return. The qualifying events are:
- Marriage
- Divorce or annulment
- Death of a spouse
- Work stoppage or work reduction (including retirement)
- Loss of income-producing property (due to disaster, fraud, or similar cause)
- Loss of pension income
- Receipt of an employer settlement payment
The common thread is that each event causes a meaningful drop in MAGI. Retirement is the most frequent trigger. Consider someone earning $150,000 in 2024 who retires in early 2025 and expects only $50,000 in pension and Social Security income going forward. Their 2026 IRMAA, set by that 2024 return, does not reflect their actual financial situation. Filing for a reduction corrects that mismatch.
Divorce works similarly. If a couple filed jointly with a combined MAGI of $250,000 and one spouse’s post-divorce income drops to $80,000, that spouse no longer belongs in any IRMAA bracket at all.
How to file the appeal
The request is made on Form SSA-44, titled “Medicare Income-Related Monthly Adjustment Amount – Life-Changing Event.” SSA accepts the form three ways:
- Online through a my Social Security account.
- By phone at 1-800-772-1213 (TTY 1-800-325-0778).
- In person at a local Social Security office (appointments recommended).
The form asks the beneficiary to identify the qualifying life event, estimate income for the relevant year, and attach supporting documents. A retirement letter from an employer, a final pay stub, a pension statement, a divorce decree, or a death certificate can all serve as evidence depending on the event.
SSA staff evaluate whether the reported change produces a MAGI low enough to reduce or eliminate the surcharge. If the agency agrees, it recalculates the premium. Beneficiaries whose premiums are withheld from Social Security checks see the adjustment in future payments. Those billed directly by CMS through the Medicare Premium Bill receive a credit or refund for months already overpaid. SSA’s Program Operations Manual System (POMS) describes the specific notices and system processes that trigger these adjustments.
No attorney is needed. No filing fee exists. The process is treated as routine workload at local SSA offices.
Timing matters. Beneficiaries can file Form SSA-44 as soon as the life-changing event occurs, even before the higher premium takes effect. Filing early can prevent overpayment entirely rather than requiring a retroactive correction. SSA does not publish average processing times for SSA-44 requests, but Medicare counselors generally advise allowing several weeks and keeping copies of all submitted documents.
Why so few people file
The process is entirely opt-in. SSA does not flag potentially eligible beneficiaries or prompt them to file after a life event. The IRMAA determination letter (SSA’s “Initial Determination Notice”) explains appeal rights in general terms, but it does not walk recipients through the SSA-44 or highlight which life changes qualify.
Many retirees assume the surcharge is final once it appears on a bill. The two-year lookback rule is confusing enough that people who do hear about IRMAA often misunderstand when and how it can be challenged. For a surviving spouse or someone navigating a divorce, a Medicare premium appeal is rarely top of mind during an already difficult transition.
Financial advisors who specialize in retirement planning describe the SSA-44 filing as one of the most overlooked savings opportunities in Medicare. The SHIP program, funded by the federal government and available in every state, offers free one-on-one counseling that includes help with IRMAA appeals. Yet awareness of SHIP itself remains low among new retirees.
What to do if SSA says no
Beneficiaries who disagree with an IRMAA determination after filing Form SSA-44 have the right to request formal reconsideration. If that fails, the dispute can move to a hearing before an administrative law judge and, in rare cases, to the Medicare Appeals Council or federal court.
For most filers, the initial request resolves the issue. The key is providing clear documentation that ties the qualifying event directly to a drop in income. Incomplete paperwork or vague income estimates are the most common reasons for delays or denials, according to Medicare counseling organizations. Keeping a copy of the submitted SSA-44 and all attachments protects against lost-document problems if a follow-up is needed.
One important catch: IRMAA resets every year
An approved SSA-44 request lowers the surcharge for the year in question, but IRMAA is recalculated annually. If income rises again the following year (because of a large Roth conversion, a capital gain from selling a home, or a return to part-time work), the surcharge can return. Beneficiaries should review their IRMAA status each fall when SSA sends new determination letters and be prepared to file another SSA-44 if a new qualifying event applies.
Conversely, once income stabilizes at a lower level, the two-year lookback eventually catches up on its own. A person who retired in 2025 with sharply lower income will see that reflected automatically in their 2027 IRMAA calculation, based on the 2025 tax return, without needing to file again.
The practical math of filing
For retirees paying hundreds of extra dollars each month on a premium set by income they no longer earn, the step is straightforward: check whether a qualifying event applies, gather the documentation, and file Form SSA-44. The potential savings, often $1,000 to $4,000 or more for a single year on Part B alone, are significant enough that skipping the filing amounts to voluntarily overpaying for Medicare coverage the government already built a process to correct.
The form is free. The appeal right is federal law. And for anyone unsure where to start, a SHIP counselor can walk through the entire process at no cost. The only real barrier is knowing the option exists.
