Why Is My Medicare Premium Higher? IRMAA Explained
Every year, millions of people on Medicare pay a Part B premium that is higher than the standard amount. If you open a letter about it and feel puzzled, you are not alone. The reason is usually a rule called IRMAA, short for Income-Related Monthly Adjustment Amount. Here is how it works in plain English.
What IRMAA Means
Most people pay the same standard Part B premium. As of October 2026, Medicare lists that amount as $202.90 a month for 2026, with a $283 yearly deductible. If your income is above a certain level, you pay an extra amount on top of that. A similar extra amount can be added to your Medicare drug plan (Part D) costs.
Who Pays the Extra Amount
According to Social Security, for 2026 the extra amount applies when your modified adjusted gross income is above $109,000 for a single person, or above $218,000 for a married couple filing together. The extra Part B amount starts at $81.20 a month and rises in steps as income rises. The Part D add-on starts at $14.50 a month. Most people are below these levels and pay only the standard premium.
Social Security usually uses your tax return from two years earlier. For 2026 amounts, that is generally your 2024 return. The numbers change each year, so check the current table on ssa.gov.
If Your Income Has Dropped
Sometimes the old tax return no longer matches your life. Social Security lists several “life-changing events” that can lead to a new decision, including:
- Marriage, divorce or the death of a spouse
- You or your spouse stopped working or cut back your hours
- Loss of income-producing property because of a disaster or other event beyond your control
- A pension plan that ended or was reorganized by an employer
- A settlement from an employer after a closure or bankruptcy
You will need proof, such as a death certificate or a retirement letter from your employer. The request is made on Form SSA-44, which you can find on ssa.gov.
What to Do Next
- Read the letter you received. It shows the income year Social Security used.
- Compare it with your own records for that year.
- If your situation has changed, gather your documents and ask Social Security about Form SSA-44.
- If you are unsure, a free Medicare counselor can help. Find one at shiphelp.org.
One safety reminder: a real Medicare premium never needs to be paid with gift cards, cryptocurrency or a wire transfer. If a caller or text pushes you to pay that way, hang up and contact Social Security directly using the number on your official letter or on ssa.gov.
This is general information, not tax or legal advice. Rules vary by situation, so check yours with Social Security or a SHIP counselor.
