Roth conversions and Medicare premiums: the warning to remember.

A conversion can raise income

The taxable portion of a Roth conversion is generally included in income for the conversion year. That can be useful planning, but it can also create side effects.

Medicare is one of the side effects

Higher income can affect Medicare Part B and Part D premiums through income-related monthly adjustment amounts. BucketSavers does not calculate those thresholds in v1, but the tool can still remind you when the issue deserves attention.

For official premium context, start with Medicare.gov.

The useful warning

The message is deliberately plain: “This could increase your Medicare premiums.” That is not a full answer, but it is often the right interruption before someone treats a bracket-only estimate as a complete tax plan.
