When does a Roth IRA conversion make sense?

A Roth conversion makes the most sense when you expect to be in a higher tax bracket in retirement than you are today, when you have years for tax-free growth to compound, or when you want to reduce future required minimum distributions (RMDs).

What taxes do I pay on a Roth conversion?

The converted amount is added to your ordinary income for the year of conversion and taxed at your marginal federal (and state) income tax rate. There is no 10% early withdrawal penalty if you follow the rules.

How long does it take to break even on a Roth conversion?

Break-even depends on your current vs. retirement tax rates and how long your money grows tax-free. Use our calculator above to model your specific scenario — most clients see a break-even within 8–15 years.
