I rolled over my wife's Roth 401k into a traditional and a Roth IRA (Her contributions were post tax, employer's contribution were pre-tax). I know that you can treat income rolled over from a traditional IRA to a Roth IRA as a contribution after 5 years, but is there any rule of treating money rolled over from a Roth 401k into a Roth IRA as a contribution? Please cite IRS regs if possible.
P.S. I'm not sure if it matters, but my wife did not have a Roth IRA prior to rolling over the Roth 401k
