A client recently came into our Manhattan office with a letter from a financial services company. Her father had passed away, and this letter confirmed she was the beneficiary of his 401(k)—an account holding nearly a million dollars. She was overwhelmed. Her first instinct was to call the company and have them send her a check. Fortunately, she called us first. That single decision likely saved her hundreds of thousands of dollars in immediate income taxes.
Inheriting a retirement account is not like inheriting a house or a bank account. These assets are governed by federal rules, and the choices you make in the first few months are often irrevocable. The goal is not just to access the money, but to be a prudent steward of a legacy built over a lifetime of work.
Your Relationship Defines Your Options
The first question I ask any client in this situation is, “What was your relationship to the deceased?” The answer determines everything that comes next. The rules for a surviving spouse are vastly different from those for a child, a sibling, or another relative.
If you are the surviving spouse, you have the greatest flexibility. You can typically treat the inherited 401(k) as your own by rolling it over into your personal IRA. This is often the most powerful choice. It allows the funds to continue growing tax-deferred, and you will not be required to take distributions until you reach the mandated age for Required Minimum Distributions (RMDs) yourself. You essentially step into your late spouse’s shoes and assume full control.
If you are a non-spouse beneficiary—a child, for instance—your path is more restricted. Following the SECURE Act, which took effect in 2020, most non-spouse beneficiaries must withdraw all funds from the inherited account within 10 years of the original owner’s death. There are no annual RMDs during that decade, but the entire balance must be zero by December 31st of the tenth year. This “10-year rule” requires careful planning to manage the tax impact of the withdrawals over time.
The Inherited IRA: A Critical Tool
For a non-spouse beneficiary, the most common and effective strategy is to direct the 401(k) plan administrator to transfer the funds into an “Inherited IRA.” This is not an IRA you contribute to; it is a custodial account designed specifically to hold inherited retirement funds. It preserves the tax-deferred status of the assets while you strategically withdraw them over the 10-year period.
Why is this so important? Because the alternative is a lump-sum distribution. Taking the entire amount at once can be a financial catastrophe. The full balance is treated as ordinary income for that tax year, potentially pushing you into the highest federal and state tax brackets. A lifetime of tax-deferred savings can be decimated by a single, ill-advised withdrawal.
The establishment of an Inherited IRA must be handled as a direct rollover or trustee-to-trustee transfer. If the check is made out to you personally, it could be considered a full distribution, triggering the massive tax liability we work so hard to avoid. Getting this procedure wrong has irreversible tax consequences.
Beneficiary Designations and the Will
People are often surprised to learn that a 401(k) passes to its named beneficiary completely outside of the will. The beneficiary designation form on file with the plan administrator is a contract, and it supersedes any instructions in a will or trust. This is why we spend so much time with our clients ensuring these forms are correctly filled out and regularly updated.
When there is no beneficiary named, or the named beneficiary is deceased, the 401(k) assets are paid to the estate. At that point, the funds are subject to the probate process in Surrogate’s Court and distributed according to the will—or state intestacy laws if there is no will. This is a worst-case scenario. It adds delay, expense, and often accelerates the tax deadline for distributions.
In New York, this process is governed by a body of law including the Estates, Powers and Trusts Law (EPTL). Specifically, EPTL § 13-3.2 confirms the rights of designated beneficiaries to receive these assets directly. A properly executed beneficiary form is the simplest and most powerful estate planning tool for retirement accounts. Ignoring it can negate an otherwise well-laid plan.
If you have recently been named the beneficiary of a 401(k), the most prudent next step is to understand all your options before you sign any paperwork from the plan administrator. We regularly schedule initial consultations to review the specific terms of an inherited plan and map out a tax-efficient distribution strategy that honors the legacy you have been entrusted with.
