Why Did My Medicare Premium Go Up After I Retired?

It seems backward, but there's usually a reason.

One of the more confusing conversations we have with new Medicare beneficiaries goes something like this:

"I just retired. I'm making less money than I was when I was working. So why did my Medicare premium go up?"

It's a fair question.

Most people assume that once they retire and their income drops, their Medicare premiums should go down too. But that's not always how it works.

In fact, it's pretty common for someone to retire and then receive a notice that they'll actually be paying more for Medicare.

The reason comes down to how Medicare calculates your premiums.

Medicare doesn't look at what you're earning today. Instead, it looks at your income from two years ago.

So, if you're paying Medicare premiums in 2026, Medicare is using your 2024 tax return to determine what you'll owe.

That can create a disconnect.

Maybe you retired in late 2025. Your income today is much lower than it was while you were working. But Medicare is still looking at those higher earning years, so your premiums haven't caught up to your current financial situation yet.

For some people, it's not just their salary that causes the increase.

Maybe you received a large bonus before retiring. Maybe you sold investments, converted money from a traditional IRA to a Roth IRA, or sold a rental property. All of those things can increase your taxable income for that year, and Medicare takes those numbers into account when calculating your premiums.

If your income rises above certain thresholds, Medicare adds what's called an Income-Related Monthly Adjustment Amount, or IRMAA, to your Part B and Part D premiums.

That's why someone can retire, have less monthly income than ever before, and still end up paying higher Medicare premiums.

The good news is that you're not necessarily stuck paying those higher premiums forever.

If your income has dropped because of a qualifying life event, retirement being one of them, Medicare gives you the opportunity to request a new review.

You'll do this by completing a form called SSA-44 through Social Security. The form allows you to explain that your income has changed because of retirement and provide documentation showing what your current income looks like.

If your request is approved, your Medicare premiums can be adjusted to better reflect your current financial situation instead of what you earned two years ago.

This is one of those things that many people simply don't know exists.

They receive the higher premium notice, assume there's nothing they can do about it, and continue paying more than necessary.

That's one of the reasons we encourage people to start planning before they retire instead of after.

A little planning around retirement income, Roth conversions, investment sales, and other taxable events can help you avoid unnecessary surprises when Medicare premiums are calculated later.

And if you've already retired and your premiums seem higher than they should be, it's worth taking a closer look. You may qualify for a reduction.

Bottom Line

Seeing your Medicare premiums increase after retirement feels backward, but it usually comes down to timing. Medicare is looking at income from two years ago, not what you're earning today.

If you've recently retired and your premiums don't seem to match your current financial picture, don't assume you're out of options. There may be a way to have your premiums adjusted, and we're happy to help you understand whether it makes sense in your situation.
