California residents often need to consider both federal tax and California state income tax when modeling a Roth conversion.
This page uses an example California marginal state tax rate so you can quickly see how state tax can change the upfront cost estimate.
The calculator does not replace California-specific tax guidance, and it does not model every credit, surcharge, or special income interaction.
