1. Identifying Account Types
Most 401(k) plans have multiple sources of funds:
- Employee pre-tax contributions (traditional 401(k))
- Employer matching or discretionary contributions
- Roth (after-tax) contributions
- Loan balances (if applicable)
Your QDRO should specify whether the alternate payee (typically the non-employee spouse) will receive a share of all sources, or only certain types. Roth and traditional funds have different tax treatment, so it’s important to separate them in the order.
