Account Types: Traditional vs. Roth 401(k)
This plan could include both traditional (pre-tax) and Roth (post-tax) 401(k) accounts. It’s critical that your QDRO specifies how to divide each type. For example, some spouses agree to split only the pre-tax funds or assign percentages to both. The tax implications vary:
- Traditional 401(k): Distributions are taxed when withdrawn.
- Roth 401(k): Qualified distributions are tax-free but subject to different handling by the plan administrator.
Failing to distinguish between Roth and traditional accounts is one of themost common QDRO mistakes.
