Medicare IRMAA 2026: $109,000/$218,000 Income Lines, Appeal Steps
IRMAA applies in 2026 if your 2024 modified adjusted gross income was above $109,000 for an individual or $218,000 for a joint return, and it is added to your Part B and Part D premiums. Because of the two-year lookback, 2026 premiums rest on your 2024 tax return. Find your Social Security notice and check which tax year it used.
TL;DR:
- IRMAA affects Part B and Part D only; it does not change Part A coverage, and about 8% of beneficiaries pay the surcharge.
- A Part D surcharge is separate from your plan premium, stays the same across plans, and must be paid to keep drug coverage.
- Request a new decision when a qualifying event, such as retirement or a spouse’s death, lowers income; appeal when Social Security used incorrect tax information.
- Married people filing separately who lived with a spouse during the tax year face lower income thresholds, while each enrolled spouse pays an individual surcharge.

What is Medicare IRMAA and which parts does it affect?
IRMAA stands for Income-Related Monthly Adjustment Amount. It is an extra charge added on top of the standard Medicare Part B premium and on top of your Part D prescription drug plan premium when your income is above certain levels. You may also see it called the Medicare income surcharge. It does not touch Part A, and it does not change what your coverage pays.
The income measure is modified adjusted gross income, or MAGI. In plain terms, MAGI is your adjusted gross income from your federal tax return plus any tax-exempt interest you earned. You do not calculate it for Social Security. The agency uses MAGI from your federal tax return, which the IRS shares with it, and typically from two years earlier.
Here is the part that reassures most readers: IRMAA only affects people whose MAGI crosses the thresholds. About 8% of beneficiaries are affected, and CMS notes that most people pay the standard monthly premium. If you are in that group, you will get a letter from Social Security explaining the extra amount.
One detail trips people up. A one-time spike, such as selling a home, converting a retirement account to a Roth, or cashing out a large investment, can push your MAGI over a line for a single year. That spike can affect your Medicare premiums later, even if your income has dropped back to normal. Knowing how the number is built is the first step to managing it.
What are the 2026 IRMAA brackets and surcharge amounts?
The 2026 standard Part B premium is $202.90 per month. If your MAGI is above the thresholds, you pay that amount plus an IRMAA surcharge that grows with each bracket. The Part D surcharge is separate and is added to whatever your drug plan charges.
CMS publishes the full 2026 Part B and Part D IRMAA tables with the exact surcharge dollars for every bracket, and the Social Security Medicare premiums page shows the same brackets with Part B and Part D amounts side by side. Check those tables for the surcharge that matches your income, since the amounts apply to each month of 2026.
Here is how the brackets work in practice:
- Standard premium only: If your 2024 MAGI was $109,000 or less (individual) or $218,000 or less (joint), you pay the $202.90 standard Part B premium and no Part B surcharge.
- First surcharge bracket: Income above those lines moves you into the first IRMAA tier, and your Part B premium rises above $202.90.
- Higher tiers: Each step up in MAGI brings a larger Part B surcharge and a larger Part D surcharge. The top tier applies to the highest earners.
- Part D surcharge: This amount is added to your plan premium. It is the same no matter which drug plan you pick, so shopping for a cheaper plan lowers the plan portion but not the surcharge.
- Married filing separately: If you lived with your spouse at any point during the tax year and filed separately, you reach higher tiers at much lower income levels than joint filers. SSA’s premium guidance explains these special rules.
- Individual versus joint: Joint thresholds are double the individual ones at the lowest line, so a couple with a combined income can stay under the surcharge longer than a single person with the same total.
Multiply the monthly surcharge by 12 to see the yearly cost. A couple should do this for both spouses, because each person on Medicare pays their own surcharge. For a household where both people are enrolled, a single tier can mean thousands of dollars over a year, which is why it pays to check your bracket before assuming the number is right.
How does Social Security determine IRMAA and when do you hear about it?
The rule is the two-year lookback. For 2026 premiums, Social Security uses your 2024 tax return, the MAGI the IRS provided to it. For a later premium year, Social Security generally uses tax information from two years earlier. This is why people who retire or lose income often get hit with a high premium in the first year of their new, lower income.
There is some flexibility in how the data is chosen. Social Security may use older data in special situations, such as when the IRS has not yet received your most recent return. It also rechecks IRS information, so your bracket can move up or down over time.
Each year Social Security sends a notice that explains your premium and, if it applies, your IRMAA. The agency’s annual verification notice guidance describes what the letter should contain: the tax year used, the income figure, the new premium amount, and your rights to ask for a new decision or file an appeal. Read it line by line. Mistakes do happen, such as an old return being used or an amended return that has not been picked up.
Three things on that letter deserve your attention:
- The tax year: Confirm it matches the lookback year you expect.
- The income figure: Compare it with your actual return. If it is wrong, an appeal is the right path.
- The bracket: Check that the surcharge matches the table for your filing status.
If everything matches but your income has since dropped for a qualifying reason, that is a different path, covered next.
What are life-changing events and how do you use SSA-44?
If your income truly went down, you do not have to wait two years. You can ask for a new decision. Social Security’s request to lower IRMAA page explains that qualifying events must be backed by documentation, and that requests can be made on SSA.gov, by mail, or in person at a local Social Security office.
Qualifying life-changing events include:
- Marriage
- Divorce or annulment
- Death of your spouse
- Work stoppage or work reduction, including retirement
- Loss of income-producing property
- Loss of pension income
- Receipt of a settlement payment from an employer or former employer due to the employer’s closure, bankruptcy, or reorganization
The SSA-44 form walks you through the process:
- Pick the event and the date. Check the event that applies and enter the date it happened.
- Report reductions that already happened. If your income has already dropped, enter the amounts for the year in question.
- Report reductions you expect. If the drop is still ahead, give your best estimate. Social Security will verify estimates with the IRS later.
- Attach evidence. Include proof such as a divorce decree, a retirement letter, an employer pension notice, or a signed tax return or IRS transcript.
Timing matters. Some new-decision requests have deadlines, so check Social Security’s official guidance and act promptly. Social Security checks what you report against IRS records, so accuracy counts.
Pro Tip: Send copies, not originals, and write the event date on every page of evidence so the reviewer does not have to hunt for it.
When should you file an appeal with SSA-561-U2?
A new decision and an appeal are not the same thing. A new decision is for when your life changed and your income fell. An appeal is for when you think Social Security used the wrong information, such as a MAGI figure that does not match your return or a return from the wrong year. Social Security’s publication on what to do if you think your premium is incorrect lays out both routes, and notes that if a qualifying event reduced your income, you may request a new decision without filing an appeal.
The first formal step is a Request for Reconsideration, form SSA-561-U2. Submit it with evidence that supports your case, such as a copy of your tax return, an IRS transcript, or an amended return showing the correct figures. Reference the date on your notice and keep proof of when you sent it.
If you disagree with the reconsideration decision, you can request a hearing before an Administrative Law Judge using form HA-501-U5. Further review is possible through the Medicare Appeals Council, and ultimately federal court, though most cases are resolved earlier.
A few habits help at every level:
- Keep a dated copy of everything you send.
- Describe your issue in one clear paragraph and tie it to a document.
- Consider asking a family member, advocate, or representative to help you manage the paperwork.
How does IRMAA affect Part D premiums and how is it collected?
The Part D surcharge is an extra amount on top of your drug plan’s premium. According to Medicare’s guide to drug coverage, Social Security deducts it from your benefit check. If your benefit is not large enough to cover it, you receive a separate bill from Medicare or another federal agency.
The key point is that there are two charges. You pay your plan’s premium to the insurance company, and you pay the IRMAA to the government. You must pay both to keep your drug coverage. Paying only the plan premium is not enough, and falling behind on the surcharge can put your coverage at risk.
Bills and notices may arrive at different times, so watch your mail and review any notices promptly. If you get a bill, do not ignore it. Compare it with your notice, confirm the amount against the 2026 table, and pay by the due date shown. If you think the amount is wrong, start the appeal process rather than withholding payment.
It also helps to know that comparing drug plans can lower the plan portion of your costs, but the surcharge stays the same no matter which plan you choose. That is why a Part D review focuses on the plan premium, the drugs you take, and the pharmacies you use.
What help is available if the premiums are hard to afford?
If higher premiums strain your budget, you have options:
- Extra Help: This program lowers Part D costs for people with limited income and resources. You can apply through Social Security or Medicare.gov. Applying can also trigger a referral to your state’s Medicare Savings Program.
- Medicare Savings Programs: These state programs can help pay Medicare premiums. Rules vary by state, so contact your state Medicaid office or your State Health Insurance Assistance Program (SHIP) to find out what you qualify for.
- Installment payments: If you owe back premiums or face severe hardship, ask Social Security about paying in installments or requesting a waiver.
Do not wait until a bill goes unpaid. Reaching out early gives you more choices.
What is your IRMAA checklist for 2026?
Work through this list in order:
- Find your Social Security notice and read it closely.
- Confirm the tax year used. For 2026, it should be 2024, or earlier in special cases.
- Pull your tax return or an IRS transcript and compare the MAGI.
- Decide your path: SSA-44 if your income dropped, SSA-561-U2 if the data is wrong.
- Gather proof, such as a divorce decree, retirement letter, employer pension notice, or amended return.
- Submit your form and keep copies.
- Follow up by phone until you get a written decision.
Free help is available. Call Social Security, call 1-800-MEDICARE, or contact your local SHIP for counseling at no cost.
Pro Tip: Call Social Security early in the day and early in the week, and write down the name of the person you speak with and the date.
Once your IRMAA status is settled, a review of your drug plan and your overall coverage can keep the rest of your costs in check.

FAQ
What will IRMAA brackets be in 2026?
The first IRMAA bracket starts when your 2024 MAGI is above $109,000 for an individual or $218,000 for a joint return. Higher brackets add larger Part B and Part D surcharges, and the full table is on the CMS 2026 fact sheet.
At what age does IRMAA go away?
IRMAA does not end at a certain age. It depends on your income from two years earlier, so it can disappear when your income falls below the thresholds. A qualifying event such as retirement can also lead to a lower surcharge through a new decision request.
How can you avoid IRMAA in 2026?
Because 2026 uses 2024 income, you can no longer change the tax year used. If your income has since dropped because of a life-changing event, you can ask Social Security for a new decision. For future years, spreading out large one-time income can help you stay below a bracket line.
What is the maximum income to avoid IRMAA?
To avoid IRMAA in 2026, your 2024 MAGI must be at or below $109,000 if you file individually or $218,000 if you file jointly. Married people filing separately face much lower limits.
