I am moving all of the funds in a traditional IRA to my Roth IRA via a Roth Conversion. All of the funds in the traditional IRA were before-tax, so I expect to need to pay an estimated quarterly tax payment on the distribution when I do the Roth Conversion. Can I just pay the expected tax payment before the April 15 deadline or do I need to submit the payment with some sort of paperwork as well?
