The Value of Keeping Your 401(k) and IRA Beneficiary Forms Up to Date

by Tyson Mavar, CFP®, Wealth Enhancement

Many Illumina employees focus on building their retirement savings but may overlook one crucial detail—updating their 401(k) and IRA beneficiary forms. After finalizing a will, it’s easy to think your estate plan is complete. However, these beneficiary documents—not your will—determine who receives your retirement assets.

In most cases, the beneficiary designations take precedence over your will’s instructions. That means your 401(k) or IRA funds are distributed based on the most recent forms filed with your plan administrator. Outdated or incomplete beneficiary information can lead to costly and irreversible outcomes after death.

Why This Matters for Illumina Employees

The beneficiary listed on your retirement plan will receive those funds directly, regardless of what your will says. This could unintentionally exclude newer family members or benefit someone you no longer wish to include. Regularly reviewing your Illumina 401(k) and any linked IRA accounts after major life events—such as marriage, divorce, or the birth of a child—helps keep your intentions consistent with your current situation.

Common Beneficiary Mistakes

Naming the estate as beneficiary
According to IRS regulations, naming your estate creates a “non-designated beneficiary.” This limits distribution options and could eliminate certain tax advantages, like the spousal rollover or 10-year payout rule.

Leaving out contingent beneficiaries
Always list both primary and contingent beneficiaries. This allows for flexibility if the primary beneficiary predeceases you or declines the inheritance, preserving potential tax efficiencies for your family.

Not updating after a rollover or transfer
When you move funds—such as rolling your Illumina 401(k) into an IRA—new beneficiary forms are required. Each account keeps its own beneficiary record, and old designations do not automatically transfer.

Overlooking spousal rights
Under federal law, a spouse is typically the default beneficiary of a 401(k). To name another beneficiary, your spouse must sign a formal waiver. This rule applies to most corporate retirement plans, including those at large employers.

Ignoring beneficiary updates after divorce
For ERISA-governed plans like 401(k)s, plan administrators must follow the designation on file even if a divorce decree states otherwise. Some states automatically revoke an ex-spouse’s designation for IRAs, but federal plans do not.

Failing to coordinate with trusts
If a trust is meant to manage your retirement assets, it must be correctly named as a beneficiary and meet IRS “see-through” rules. Otherwise, your trust may lose intended tax and estate planning advantages.

The Value of Regular Review

Even a well-organized estate plan can be undermined by outdated beneficiary forms. Periodically confirming your Illumina retirement account designations can help align your estate intentions and reduce future tax complications.
