How to lower IRMAA

Start with the two-year lookback

IRMAA is not based on your income this month. It is based on a tax return from two years earlier. For 2026 premiums, Social Security generally starts with income from 2024. That delay explains most surprises. A bonus, a property sale, or a retirement distribution can raise a premium long after the event feels finished.

Before you change anything, find the income figure that was actually used. Compare it with the bracket table. If the figure is wrong because of a listed event, you may have a path to a review. If the figure is right, the question becomes how to plan the next income year rather than how to argue with the current one.

File Form SSA-44 after a life-changing event

Form SSA-44 is the main correction route. It tells Social Security that a listed event changed your income, and it asks the agency to use a newer figure. The form has to match the event and the proof has to support the new number.

The strongest filings are specific. A retirement letter with a date is stronger than a statement that work became less busy. A pension termination notice is stronger than a general claim that income fell. A marriage certificate is stronger than a description of a new household.

File the form, keep a copy, and ask how the office will contact you. An appeal does not lower the premium automatically while it is pending. The review has to finish and the decision has to be issued. If the decision is still wrong, ask for the next level of review rather than sending the same form again.

Time large income events

The second lever is timing. Because the premium uses a two-year-old return, income in one year can set a premium two years later. If you are near a bracket line, the exact year of a sale or distribution can matter more than the size of the event.

Suppose you expect a large one-time distribution. Doing it in a year when your income is otherwise low may keep the total below the next bracket. Doing it in an already high-income year may push you over a line for two premium years if the income repeats. This is planning, not a guarantee, and it needs a tax preparer who can see the whole return.

The same logic applies to a business sale, a large capital gain, or a final paycheck with unused leave. The premium year is not the year you feel the cash. It is the year the old return is used.

Check the next cliff before a Roth conversion

A Roth conversion adds to modified adjusted gross income in the year of the conversion. That can move you into a higher IRMAA tier two years later. The right question is not whether the conversion is a good idea in general. The right question is how much room you have before the next bracket.

Use the IRMAA calculator with the projected income before the conversion. Read the headroom to the next tier. Then decide whether to convert all at once, split the conversion across two years, or wait until a lower-income year. A conversion that crosses the line can cost more than expected in Medicare premiums, even if it saves tax later.

The calculator does not model the income tax on the conversion. It only shows the IRMAA tier and the surcharge. Use a tax preparer for the combined decision.

Use the right income figure

IRMAA uses modified adjusted gross income, not salary and not taxable income in the everyday sense. The figure starts with adjusted gross income and adds certain items the tax rules require. That is why a tax-exempt interest payment or a foreign income exclusion can still matter for Medicare.

Do not estimate from your bank balance. Do not use the income you expect next year without saying so. Either use the lookback-year return, or use the newer documented figure you are asking SSA to accept. Mixing the two produces a number that does not match any official decision.

What does not lower IRMAA

Choosing a cheaper Medicare Advantage plan does not lower the Part B surcharge. Buying a Medigap policy does not lower it. A Medicare Savings Program helps with premiums and cost sharing for people with low income and resources, but it does not rewrite the IRMAA table.

A Part D plan with a lower premium can lower the plan premium part of your drug coverage. It does not lower the Part D IRMAA add-on, which is set by income. If you have no Part D plan, you generally do not pay the Part D IRMAA amount, but the Part B surcharge can still apply.

Be careful with advice that promises a simple fix. The legitimate levers are evidence, timing, and the correct income figure. Everything else is either a different program or a sales pitch.

How much can you earn before IRMAA

For 2026, a single filer pays the standard premium at or below $109,000.00 of modified adjusted gross income. A married couple filing jointly pays the standard premium at or below $218,000.00. Married filing separately has a much lower first threshold at $109,001.00.

These are cliff lines, not gradual phases. One dollar above the line can start the surcharge for the whole year. That is why the headroom number matters more than the tier label.

Worked example

A single filer expects $137,001.00 of modified adjusted gross income. That is inside the second IRMAA tier. The Part B total for that tier is $405.80, and the Part D add-on is $37.50. The combined monthly surcharge is $240.40, or $2,884.80 a year.

If the same person had kept income at $109,000.00, the standard premium would apply and the surcharge would be zero. The difference is $240.40 a month. That is the amount a timing decision, an appeal, or a conversion plan is trying to protect.

Keep a paper trail

Every legitimate route depends on evidence. Keep the tax return that produced the income figure, the premium notice that shows the tier, and the proof for any event you use in an appeal. If you call Social Security, write down the date, the representative’s name if it is given, and what you were told to send.

A paper trail also helps at tax time. If a conversion or a sale is planned, keep the projection and the final return together. The following year, you can see whether the premium matched the plan. That is how a household learns where its own cliffs are.

Do not rely on a verbal promise that the premium will be fixed. Ask for the decision in writing and check the next notice. A pending review is not the same as an approved change.

Can you lower IRMAA after retirement

Retirement can be a qualifying life-changing event for an SSA-44 request. The event has to be documented, and the newer income figure has to support a lower tier. A retirement date alone is not enough if the income used for the premium is still above the threshold.

The first step is to compare the income on the notice with the income after retirement. If the notice uses a working year and the current year is materially lower, the form may fit. If the notice already uses a low-income year, the request may not change the tier.

The evidence usually includes a retirement letter, a final pay stub, a pension or annuity statement, or a Social Security award letter. The exact documents depend on the event and the income source. Ask the local office what it wants rather than sending everything.

Timing matters. The request should be filed when the event and the new income are documented. A request based on an expectation can be premature. A request filed long after the premium year may still be reviewed, but the adjustment may be limited.

A lower IRMAA tier is not the same as a lower tax bill. Retirement can reduce income and also change the tax brackets, the Roth conversion window, and the Medicare premium two years later. Look at the whole picture with a tax preparer before making a move.

If the request is approved, check the next premium notice. Keep the decision with the tax records. If it is denied, ask why and whether a different event or a corrected income figure would qualify.

Three honest caveats

1. A lower IRMAA tier is not the same as a lower tax bill. A Roth conversion can raise both, and the combined effect needs a tax preparer.
2. Form SSA-44 depends on a listed event and proof. A normal market loss or a general claim that income feels lower is usually not enough.
3. This page is guidance, not tax or legal advice. Confirm the income year, the filing status, and the current table with the official sources before you act.

Frequently asked questions

How much can you earn before IRMAA?

For 2026, the standard tier ends at $109,000.00 for a single filer and $218,000.00 for a married couple filing jointly. The first surcharge starts one dollar above the line.

Can I appeal IRMAA without a life-changing event?

Form SSA-44 is built around listed life-changing events. Without one, the usual route is to correct the income record if it is wrong, or to plan the next income year.

Does a Roth conversion always raise IRMAA?

Only if the conversion raises modified adjusted gross income enough to cross a threshold in the lookback year. A small conversion under the first line may not change the tier.

Can I split a Roth conversion across two years?

Often you can choose the amount and the year, but the tax rules and your other income determine the result. Ask a tax preparer before splitting a conversion.

Does IRMAA apply to both spouses?

Each spouse who is enrolled in Medicare can pay the surcharge. A joint return can therefore produce two IRMAA amounts, one for each spouse.

Do Medicare Advantage or Medigap premiums count toward IRMAA?

No. IRMAA is an income-based add-on to Part B and Part D. It is separate from the premium you pay for a Medicare Advantage or Medigap plan.
