The step-by-step process how-to actually convert a traditional IRA to a Roth IRA is actually fairly easy. First, notify the custodian of your traditional IRA that you would like to convert the IRA to a Roth IRA. They may have you sign a form saying that you understand what you are doing, but they will handle the rest.
Then, you’ll get a form from the custodian that you will use to file your federal income taxes and pay the tax required on the conversion on your regular income tax form, usually a Form 1040.
If you made non-deductible contributions to the traditional IRA, you may also need to file Form 8606 to account for those contributions so that you do not have to pay taxes on that part of the conversion.
That’s it.
