1. Traditional vs. Roth Account Distinctions
If the plan contains both traditional (pre-tax) and Roth (post-tax) subaccounts, your QDRO should specify how both are being divided. Roth 401(k) funds have favorable tax treatment but different distribution rules.
- Traditional 401(k): Taxes are deferred until withdrawal.
- Roth 401(k): Contributions are made after-tax, but qualified withdrawals are tax-free.
Be sure your QDRO keeps the tax status of each account type intact, or you might face unintended taxes or penalties.
