1. Account Types: Traditional vs. Roth
401(k) accounts may include both pre-tax (traditional) and after-tax (Roth) contributions. These two account types are treated differently for tax purposes:
- Traditional 401(k): Taxable when distributed.
- Roth 401(k): Tax-free if conditions are met (e.g., age and holding period).
Your QDRO must specify whether the division includes both types and be clear on how the transfer is allocated proportionally between these accounts.
