1. Roth vs. Traditional Accounts
Many modern 401(k) plans include both pre-tax (traditional) and post-tax (Roth) contributions. This matters when preparing a QDRO because transfers need to keep the tax character of each source intact. For example, Roth assets remain Roth when transferred to the alternate payee. If you’re unaware of this and draft the QDRO improperly, the alternate payee could be hit with unintended taxes or even penalties.
