Inherited Vanguard 401(k): Beneficiary Claim Guide
Vanguard routes death claims through a dedicated inheritance team, and the process is manageable — if you know the sequence and refuse the one option that can never be repaired.
Below: the exact claim steps, the titling format an inherited IRA must use, and how the SECURE Act 10-year rule and 2025 RMD enforcement shape your distribution timeline.
The one mistake that cannot be undone
A non-spouse beneficiary has NO 60-day rollover. If the plan cuts a check in your name and you deposit it, the entire account becomes taxable income that year — there is no Rev. Proc. self-certification, no IRS letter, no fix. The ONLY safe move is a direct trustee-to-trustee transfer into a properly titled inherited IRA. If anyone offers to "just send you a check," stop the call and get help first.

Ordinary transfer processing: 5-7 business days (ACATS); 2-3 weeks for paper — death claims add a document-review stage on top, so budget extra weeks beyond that.

Vanguard quirks that also bite beneficiary transfers:
- Vanguard's outbound-transfer form is at 'Profile & account settings → Move money out → To another firm'. It's easy to miss — they bury it deeper than other custodians.
- If your 401(k) is at Vanguard Retirement Plan Services (employer plan), the path is different — log into Vanguard.com/retirementplans, not my.vanguard.com.
- Vanguard requires a Medallion Signature Guarantee for transfers over $100K (NOT a notary — a Medallion stamp, typically from a bank you have a relationship with). Get this in person before you start; finding a Medallion provider can take a couple days.
How to claim, step by step
- 1
Order 3–5 certified copies of the death certificate — Vanguard and every other institution will each want one.
- 2
Call Vanguard's beneficiary-services line and ask for the "death claim" or "beneficiary distribution" package for the specific plan. Have the deceased's SSN, date of death, and your ID ready.
- 3
Ask Vanguard to CONFIRM you are the beneficiary of record before discussing options — plan documents control, not the will.
- 4
Before signing anything, decide the destination: a properly titled inherited IRA (e.g., “Jane Doe, deceased, FBO John Doe, beneficiary”). Titling errors are treated as full distributions.
- 5
Insist on a DIRECT trustee-to-trustee transfer into the inherited IRA. Decline any option that mails you a check payable to you personally.
- 6
Get the transfer confirmation in writing, then calendar your RMD obligations for the current year — the deceased's year-of-death RMD may still be due.
Your distribution clock (2026 rules)
- Most non-spouse beneficiaries must empty the account within 10 years of the death — and if the owner had already started RMDs, annual withdrawals are required in years 1–9 (enforced since 2025, with a 25% excise tax behind them).
- The deceased's year-of-death RMD may still be due on YOUR calendar while the claim processes.

Common questions
Does Vanguard require a Medallion signature guarantee for beneficiary claims?
Plan on it for anything leaving Vanguard: even Vanguard's ordinary outbound rollovers frequently require a Medallion stamp, and death claims headed to an outside custodian face the same or stricter documentation review. Claims settled into a Vanguard inherited IRA typically avoid the stamp entirely — a real reason many beneficiaries settle in place first and transfer later.
Who actually handles the claim at Vanguard?
A dedicated inheritance/transition team — ordinary phone reps hand you off. Ask specifically for beneficiary services and have them send the claim kit; if the account is an employer 401(k) administered by Vanguard, the employer's plan rules apply first, so the kit will be specific to that plan.
