Traditional vs. Roth Contributions
Most 401(k) plans allow participants to contribute both pre-tax (traditional) and post-tax (Roth) dollars. It’s essential for your QDRO to clarify how each type of account is to be divided. The reason? Roth accounts have already been taxed, meaning future withdrawals (if qualified) are tax-free. Traditional contributions are taxed when withdrawn.
If your spouse has both, you need to decide whether to divide each account separately, proportionally, or exclude one. Failing to address both types can cause delays and tax surprises down the road.
