Understand the Different Types of Contributions
The Withumsmith+brown 401(k) Employee Savings Plan likely includes multiple types of contributions:
- Employee Deferrals (Pre-Tax): These funds are typically 100% vested and part of the marital estate.
- Employer Matching Contributions: These may be subject to a vesting schedule.
- Roth Contributions: These are post-tax and taxed differently than pre-tax contributions during distribution.
Your QDRO must specify whether you’re dividing just the vested account balance or both vested and unvested portions. It’s also crucial to identify Roth and traditional accounts separately so that tax treatment is preserved.
