401(k) Succession After Death: Key Steps for Beneficiaries (2026)

Beneficiaries must understand that a 401(k) transfers directly to the named beneficiary, not through the will. Contact the plan provider or employer HR to verify primary and contingent beneficiaries, and ensure all forms are updated with life changes. After death, the plan administrator will not automatically distribute funds. The beneficiary must submit a death certificate and a distribution request form to initiate a lump-sum payout, transfer to another account, or establish a beneficiary account, as required by each institution. Spouse beneficiaries have options to roll over funds or take a lump sum, while non-spouse beneficiaries typically must withdraw the full amount within 10 years under the SECURE Act. Pretax balances are taxed upon withdrawal; Roth balances are generally tax-free. Failure to name or update beneficiaries may result in the 401(k) going through probate. Always seek tax and legal advice before acting, and ensure copies of the death certificate are provided to all relevant institutions.
