A Roth Conversion Can Affect More Than Your Tax Return
One of the biggest mistakes with Roth conversions is evaluating them only through the lens of this year's taxes.
The converted amount increases taxable income in the year of the conversion.
But that income can affect other parts of your financial landscape too.
One example is Medicare.
Conversion income contributes to the modified adjusted gross income used to determine Medicare Part B and Part D income-related premiums two years later.
That's why the question shouldn't simply be:
“How much can I convert?”
It should be:
“How much makes sense within the rest of my plan?”
Taxes.
Medicare.
Cash flow.
Future required distributions.
Legacy goals.
They aren't separate decisions.
They're different parts of the same financial landscape.
Good planning connects them before making the move.
