Inherited 403b Rules for Beneficiaries

Inheriting a retirement account involves navigating a specific set of rules. A 403(b) plan, a retirement savings vehicle for employees of public schools and certain non-profits, is governed by federal regulations that dictate how its assets are passed to the next generation. Understanding these rules is the first step for a beneficiary to properly manage the funds they have received.

The process begins with notifying the plan provider of the account holder’s death, which requires submitting a death certificate. The provider then verifies the beneficiary designation on file and contacts the named individuals to present their distribution options.

Determining Your Beneficiary Category

The first step after being notified of an inheritance is to determine your specific beneficiary classification, as this dictates the withdrawal rules you must follow. The SECURE Act of 2019 established distinct categories, and the subsequent SECURE 2.0 Act of 2022 introduced further refinements to these rules. Your relationship to the deceased account owner places you into one of them.

A spousal beneficiary is the surviving spouse of the 403(b) account owner. This category provides the most flexibility in terms of how the inherited funds can be managed. Federal law often requires a married individual to name their spouse as the primary beneficiary for at least 50% of the account unless the spouse formally waives this right.

A non-spouse beneficiary who is not an adult child may fall into the category of an Eligible Designated Beneficiary (EDB). This group includes minor children of the original account owner, individuals who are disabled or chronically ill under specific IRS definitions, and any beneficiary who is not more than 10 years younger than the deceased account owner.

The next classification is a Designated Beneficiary (DB), which is any individual who does not qualify as a spouse or an EDB. The most common example of a DB is an adult child of the account holder. Finally, a Non-Designated Beneficiary (NDB) is an entity rather than a person. This includes the deceased’s estate, a charity, or certain types of trusts that do not meet specific legal requirements.

Distribution Rules for Each Beneficiary Type

Spousal beneficiaries have the most options. They can treat the inherited 403(b) as their own by rolling the assets into their personal IRA or another qualified retirement plan. This action allows the funds to continue growing tax-deferred and consolidates them with the spouse’s own retirement savings. Alternatively, a spouse can open an inherited IRA and take distributions based on their own life expectancy or, if they choose, follow the 10-year rule. Some 403(b) plans may also permit the surviving spouse to simply remain a beneficiary of the existing account.

Eligible Designated Beneficiaries (EDBs) can take advantage of a “stretch” provision, allowing them to take distributions over their own life expectancy. This method can extend the tax-deferred growth of the account for many years. A key aspect of this rule is that the EDB status can be temporary. For example, when a minor child of the account owner reaches the age of 21, their EDB status ends, and they become subject to the 10-year rule from that point forward.

Designated Beneficiaries (DBs) are subject to a strict 10-year rule. This rule mandates that the entire balance of the inherited 403(b) must be withdrawn by December 31 of the 10th year following the year of the original owner’s death. If the original account owner died after they had begun taking their own RMDs, you must take annual RMDs in years one through nine. If the owner died before they had started taking RMDs, no annual distributions are required during the 10-year period. In either case, the full remaining balance must be withdrawn by the end of the 10th year.

Non-Designated Beneficiaries (NDBs), such as an estate or a charity, face the most restrictive timelines. The specific rule depends on when the original account owner passed away relative to their Required Beginning Date (RBD) for taking RMDs. If the owner died before their RBD, the entire account must be distributed within five years. If the owner died on or after their RBD, distributions must be taken over the deceased’s remaining single life expectancy, as calculated in the year of their death.

Tax Treatment of Inherited 403(b) Distributions

For a traditional 403(b), any distributions the beneficiary receives are taxed as ordinary income in the year the withdrawal is made. These withdrawals are not subject to the 10% early withdrawal penalty, regardless of the beneficiary’s age. Plan administrators are often required to withhold 20% of a distribution for federal income taxes unless the funds are moved via a direct rollover to an inherited IRA.

If you inherit a Roth 403(b), the rules are different. Qualified distributions from a Roth account are generally received tax-free by the beneficiary. For a distribution to be qualified, the original account owner must have held the Roth account for at least five years.

A spousal beneficiary who chooses to execute a direct rollover of the inherited 403(b) into their own retirement account does not trigger a taxable event. This move is considered a transfer, not a distribution, so taxes remain deferred. The surviving spouse will only pay income taxes when they later take distributions from their own account, following the standard rules for retirement withdrawals.

Beneficiaries subject to the 10-year rule have some control over their tax burden. Since the entire amount must be withdrawn within the 10-year period, you can strategically time your distributions. For instance, you might spread withdrawals over several years to avoid a large, single-year distribution that could push you into a higher marginal tax bracket. This allows for a degree of tax planning to manage the financial impact of the inheritance.

Process for Claiming and Managing the Account

To begin the claim, you will need to collect specific documents. The primary document required is a certified copy of the death certificate. You will also need to provide your own government-issued identification to verify your identity as the named beneficiary.

The next step is to contact the plan administrator, which is the financial institution or employer that manages the 403(b) plan. You can typically find their contact information on a statement from the deceased’s account or by contacting their former employer. The administrator will provide you with the necessary death benefit claim forms and guide you through their specific procedures.

Completing the claim forms is where you will formally elect your chosen distribution option. Whether you are initiating a rollover to your own IRA, establishing a new inherited IRA, or requesting a lump-sum distribution, you will make this selection on the provided paperwork. Once the completed forms are submitted, the plan administrator will process your request.
