Divorce and the Igm Biosciences, Inc.. 401(k) Plan: Understanding Your QDRO Options

Dividing retirement assets during a divorce isn’t always simple—especially when you’re dealing with a 401(k) plan like the Igm Biosciences, Inc.. 401(k) Plan. A Qualified Domestic Relations Order (QDRO) is the legal tool used to divide retirement accounts in divorce without triggering tax penalties or early withdrawal fees. But every plan is different, and when you’re dealing with employer-sponsored 401(k)s—especially from corporations in the general business sector—there are key details you need to get right.

Before we get into the process of dividing this specific account, here’s what we know about the plan:

• Plan Name: Igm Biosciences, Inc.. 401(k) Plan
• Sponsor: Igm biosciences, Inc.. 401(k) plan
• Plan Address: 325 EAST MIDDLEFIELD ROAD
• Plan Sponsor Details: 20250718115337NAL0000786931001, effective from 2018-01-01 through at least 2024-12-31
• Plan Type: 401(k) – defined contribution retirement savings
• Industry: General Business
• Organization Type: Corporation
• Plan Status: Active
• Plan Number: Unknown (required for QDRO)
• EIN: Unknown (required for QDRO)
• Assets, Participants, Contributions: Currently unknown

Despite having limited public information, a QDRO can still be effectively created for this plan if the missing details like EIN and Plan Number are obtained from the plan administrator.

Since the plan is a 401(k), it has particular characteristics that require attention during division:

• Employee Contributions: These are typically fully vested and can be divided without issue.
• Employer Contributions and Vesting: Here’s where things can get tricky. Many employer contributions are subject to a vesting schedule. If the plan participant is not fully vested at the time of divorce, the alternate payee (the non-employee spouse) may not be entitled to those unvested amounts.
• Loan Balances: If the employee spouse has taken loans against their 401(k), it affects how much money is available for division. QDROs must clearly state whether the alternate payee’s share is calculated before or after deducting the loan.
• Account Type – Roth vs. Traditional: This plan may have both types of subaccounts. Roth contributions are post-tax, while traditional contributions are pre-tax. The QDRO should specify how to divide each account type to avoid tax and distribution issues later.

401(k) division may seem routine to some attorneys or paralegals, but that assumption can lead to obstacles—especially with plans like the Igm Biosciences, Inc.. 401(k) Plan. Here are a few common pitfalls:

• Failing to Obtain Plan-Specific QDRO Guidelines: Every plan has different administrative rules for formatting and processing QDROs. Always request the guidelines from the plan administrator.
• Ignoring Unvested Contributions: If the participant is only partially vested in their employer match, the QDRO needs to reflect that. Otherwise, the alternate payee may believe they’re entitled to more than the plan will pay.
• Not Accounting for Outstanding Loans: A $50,000 401(k) balance might include a $15,000 loan. The actual divisible amount is only $35,000 unless the QDRO says otherwise.
• Mixing Roth and Traditional Funds: These are taxed differently. Make sure your QDRO specifies whether the Roth and traditional components should be split proportionally or handled separately.
