Q&A: How capital gains boost Medicare premiums

Dear Liz: We are retired and living mainly on a pension, which covers our month-to-month needs. We own our house outright and are considering downsizing. When we do that, will the capital gain cause our Medicare premiums to go up two years later? If so, will it automatically go down again after one year?

Answer: A big-enough capital gain can trigger Medicare’s income-related adjustment amount, which are surcharges on your Part B and Part D premiums. As you note, there’s a two-year delay between the higher income on your tax returns and higher premiums.

If you’ve had a life-changing event — marriage, divorce, a spouse’s death or loss of income, for example — you can appeal the increase by filing form SSA-44. Otherwise, consider saving some of the home sale profits to cover your higher premiums for that one-year period.
