Inherited 401k Rollover Options

You Can't Just Roll an Inherited 401(k) Into Your Own IRA

That's the mistake people make most often. A non-spouse beneficiary who inherits a 401(k) cannot roll it into their own IRA. Only surviving spouses have that option. A direct trustee-to-trustee transfer to an inherited IRA preserves tax deferral; a cash distribution paid to the beneficiary is generally taxable, and any separate IRA contribution must meet the annual contribution and compensation limits.

The options available to you depend on two things: whether you're the surviving spouse or a non-spouse beneficiary, and what the plan document allows. 401(k) plans aren't required to offer the same flexibility as IRAs, so the plan's own rules narrow your choices before the IRS rules even come into play.

Surviving Spouse Options

Surviving spouses have the widest range of choices:

Roll into your own IRA. The inherited 401(k) becomes your IRA — not an inherited IRA, but your own. You contribute to it and name your own beneficiaries. RMDs generally begin for the calendar year you reach your applicable age (73 for people born 1951–1959, 75 for those born in 1960 or later, and an earlier age for prior cohorts), though you can delay the first distribution until April 1 of the following year. This is usually the best option for a surviving spouse who doesn't need the money now and wants to defer taxes.

Roll into your own employer's 401(k). If your employer's plan accepts incoming rollovers, this consolidates everything in one place. Same tax deferral benefits as rolling into your own IRA, plus potential creditor protection under ERISA.

Transfer to an inherited IRA. The account stays titled in the deceased's name, for your benefit. You take life-expectancy distributions based on your age. The key advantage: penalty-free withdrawals at any age, even before 59½. If you're under 59½ and need access to the funds, this option avoids the 10% early withdrawal penalty that would apply if you rolled into your own IRA.

SECURE 2.0 Section 327 election. For employer plans specifically, you can elect to be treated as the deceased employee for RMD purposes. This uses the Uniform Lifetime Table (more favorable than the Single Life Table); if the employee died before their RBD, it also defers your first RMD until the year they would have reached their applicable RMD age. This is a newer option that many plan administrators are still implementing.

Lump-sum distribution. Take the entire balance at once. The full amount is taxable as ordinary income in the year received. Rarely makes sense unless the balance is small or you have unusual tax circumstances.

Non-Spouse Beneficiary Options

Transfer to an inherited IRA. This is the standard path. You request a direct trustee-to-trustee transfer from the 401(k) plan to an inherited IRA at a retail brokerage (Fidelity, Schwab, Vanguard, etc.). The account is titled in the deceased's name, for your benefit. You get more investment choices than the 401(k) offered and more control over distribution timing within the 10-year window.

Stay in the plan. Some 401(k) plans permit non-spouse beneficiaries to remain in the plan. If the plan's investment options are good and the fees are reasonable, this can be a valid choice. But many plans don't allow it — they require beneficiaries to transfer out within a set period (often 12 months).

Lump-sum distribution. Same as above — generally a taxable event. A taxable nonperiodic distribution to a non-spouse beneficiary generally has 10% federal withholding by default, unless the beneficiary elects another rate. The mandatory 20% rate generally applies to eligible rollover distributions, which beneficiary payments usually are not.

You cannot roll it into your own IRA or your own 401(k). This cannot be emphasized enough. Only spouses can do this. A direct transfer to an inherited IRA preserves tax deferral; a cash distribution to the non-spouse beneficiary is generally taxable. Any separate contribution to the beneficiary's own retirement account must meet the ordinary contribution rules.

The Direct Transfer Requirement

Any movement of inherited 401(k) money must be done as a direct trustee-to-trustee transfer — from the plan administrator directly to the receiving custodian. You cannot take a check made out to you and deposit it within 60 days (the indirect rollover method). That 60-day rule applies only to your own retirement accounts, not inherited ones.

If the plan administrator sends you a check made out to the plan "FBO" (for the benefit of) the deceased, endorse it and send it to the receiving custodian with the inherited IRA paperwork. If they send a check made out to you personally, you've received a taxable distribution and cannot undo it.

Timing and the Year-of-Death RMD

Before any rollover or transfer, the year-of-death RMD must be satisfied if the deceased had reached their Required Beginning Date and hadn't completed their full RMD for the year. This obligation cannot be rolled over — it must be taken as a distribution and reported as income.

Once the year-of-death RMD is completed, the remaining balance can be transferred. Most plan administrators won't process the transfer until they've confirmed the year-of-death RMD has been addressed.

Which Option Should You Choose

For surviving spouses under 59½ who need access to the money: inherited IRA (penalty-free withdrawals). For surviving spouses who don't need the money: rollover to own IRA (maximum deferral). For non-spouse beneficiaries: transfer to inherited IRA for investment flexibility and controlled distributions over the 10-year window.

The Retirement Account Claims toolkit includes a rollover decision tree for each beneficiary type, plus the custodian scripts and document checklists needed to execute the transfer.
