The order in which Roth IRA assets are distributed. Assets are distributed from a Roth IRA in the following order:

1. IRA participant contributions
2. Taxable conversions
3. Non-taxable conversions
4. Earnings


This set of rules is used to determine the applicable tax treatment of a nonqualified Roth IRA distribution.

Under the aggregation and ordering rules, all of an individual's Roth IRAs are treated as a single account.
