- Rollover the contributions to a traditional IRA or a Vanguard Individual Retirement Account (IRA).
- Convert the traditional IRA to a Roth IRA, which allows you to pay taxes on the converted amount in the year of conversion.
- Contribute after-tax dollars to the Roth IRA, which can be done through Vanguard's website or mobile app.
