I just received an inheritance. Will it raise my Medicare premiums, and for how long?
Answered by 4 licensed agents
Medicare looks at your taxable income to determine whether you pay an additional amount for Part B and Part D. That additional charge is called IRMAA — the Income-Related Monthly Adjustment Amount.
So the first question is: What did you inherit?
Cash or property you inherit is generally not counted as taxable income just because you received it. But what happens afterward can matter. Interest, dividends or rent produced by inherited assets may increase your income. Selling inherited property could create a taxable gain. And taxable withdrawals from an inherited traditional IRA generally count as income.
The timing is important too. Medicare generally looks at your tax return from two years earlier when determining IRMAA. For example, income reported on a 2026 tax return would generally affect your Medicare premiums in 2028.
If the inheritance creates a large amount of taxable income in only one year, the higher Medicare premium may also last only one year. If the inherited assets continue producing taxable income, or you continue taking taxable distributions from an inherited retirement account, the higher premiums could continue longer.
One important point: receiving an inheritance by itself is not one of Social Security's listed life-changing events for lowering IRMAA. However, if the inheritance followed the death of your spouse, death of a spouse is a qualifying life-changing event and should be reviewed separately.
So before assuming your Medicare premium will increase, look at what you inherited, how it will be taxed, and which tax year the income will appear in. That will tell you whether Medicare is likely to be affected — and for how long.

Long Answer: Medicare uses your Modified Adjusted Gross Income from two years prior to determine if you owe an IRMAA (Income-Related Monthly Adjustment Amount), which is an extra surcharge added to your Part B and Part D premiums. If your income crosses specific thresholds, your premiums will go up. An inheritance will only trigger higher premiums if it generates taxable income, such as taxable withdrawals from an inherited retirement account (Traditional IRA or 401k) or ongoing dividends from inherited stocks.
