Terms of Use   

A Conversion Roth IRA is defined as a Roth IRA that receives money from Traditional IRAs through a conversion, rollover or direct transfer.

If an account is designated as a Conversion Roth IRA, then that account can only accept IRA conversion contributions made in a single year. A separate Conversion Roth IRA must be established each year in which an individual desires to convert assets into a Roth IRA.
Contributions are permitted until April 15th for the prior tax year.
