Tax payment method
Learn how the Roth Conversion Calculator models IRA withholding and possible early distribution penalty assumptions.
If age is below 59.5 and no exception is selected, the calculator models a 10% penalty only on the amount withheld from the IRA for taxes.
Withholding from the IRA means part of the IRA distribution is assumed to be used for taxes rather than converted to Roth.
For users under 59.5, the calculator models a possible 10% early distribution penalty on the withheld amount unless the penalty exception toggle is enabled.
The estimate is simplified and does not replace professional review of withholding rules, exceptions, account paperwork, or tax return treatment.
Open the calculator with this tax payment method prefilled, then adjust withheld amount, age, penalty exception, income, basis, and conversion amount.
