Inheriting a 403(b): What Non-Spouse Beneficiaries Must Do

The 403(b)'s Two Product Types: Why It Matters

Unlike a 401(k), which almost always holds mutual funds in a custodial account, a 403(b) plan can hold one of two very different products:

1. Custodial accounts (mutual funds)

These look and function much like a 401(k) or brokerage IRA. The account holds mutual funds or ETFs in a custodial arrangement. Rolling these to an inherited IRA is straightforward: a direct trustee-to-trustee transfer, identical to the 401(k) process. Most plans at large hospitals and universities use this format.

2. Annuity contracts (insurance products)

Many 403(b) plans — especially those offered by older school districts, smaller nonprofits, and religious organizations — hold individual insurance company annuity contracts. This is where the complications arise:

• Surrender charges. Annuity contracts typically carry surrender periods of 6–8 years with declining exit fees (often starting at 6–7% and declining 1% per year). Most contracts include a death benefit exception that waives the surrender charge when the account owner dies — but not all do. Your first step is to request the contract terms from the insurance company, not the employer plan administrator.
• Different custodians. The "plan administrator" may be the employer's HR department, but the actual contract is held by an insurance company (Lincoln, TIAA, Voya, AXA Equitable, or similar). You'll need to contact both.
• Rollover to inherited IRA requires liquidation. You can roll an annuity contract's cash value to an inherited IRA, but it requires surrendering the contract (or requesting a direct rollover). If the contract has a no-surrender-charge death benefit provision, this happens cleanly. If surrender charges apply, you'll either pay the charge or keep the annuity in-place and take IRC §72(s) distributions — a less flexible option.
• In-plan distribution option. For annuity contracts, beneficiaries also have the option to elect an annuitized death benefit (monthly income over a fixed period or lifetime). This avoids surrender charges but locks in a payment schedule that may not be optimal for your tax situation.

Spouse vs. Non-Spouse: Different Rules

Before anything else, confirm your relationship to the deceased — it determines what options are available.

Surviving spouse options

• Roll into your own IRA. The cleanest option for most spouses. The account becomes yours entirely — your RBD governs, your beneficiary designation controls what happens next, and inherited-account distribution rules no longer apply. Usually the best option for spouses who don't need the money immediately.
• Keep as inherited 403(b). Preserves plan investment options and allows penalty-free withdrawals before age 59½ if you need income now.
• Roll to an inherited IRA. Provides investment flexibility and delays RMDs if the spouse wants to defer distributions.

Non-spouse beneficiary options

If you are a child, sibling, parent, domestic partner, or anyone other than a surviving spouse:

• Roll to an inherited IRA (recommended for most). Preserves investment flexibility, avoids immediate full taxation, and starts the 10-year distribution clock in a controlled way.
• Keep in the plan. Allowed only if the plan's terms permit it. Many plans require distributions within a plan-specified timeframe that can be shorter than 10 years.
• Take a lump sum. The entire pre-tax balance is added to your ordinary income in the year received. Usually the worst tax outcome for large accounts.

Rolling an Inherited 403(b) to an Inherited IRA

The mechanics are similar to an inherited 401(k) but involve one or two more parties if the account is an annuity contract.

For custodial accounts (mutual funds)

1. Open an inherited IRA at the brokerage of your choice (Fidelity, Vanguard, Schwab, etc.). The account must be titled as an inherited/beneficiary IRA — for example: "Jane Doe (deceased), for the benefit of Michael Doe, beneficiary." Never commingle with your own IRA.
2. Contact the plan administrator — typically the employer's HR or benefits office. Request the direct rollover paperwork. Provide your inherited IRA account number and custodian transfer details.
3. Request a direct trustee-to-trustee transfer. The check or wire must go to the new IRA custodian, not to you.
4. Confirm the 1099-R is coded correctly. Distribution code "4" (death distribution) is correct. Code "1" or "2" would indicate an error requiring correction.

For annuity contracts

1. Contact the insurance company directly. The plan administrator may not have the annuity contract details. You need the insurance company's death claim department.
2. Request the death benefit certificate and contract terms. Confirm whether the death benefit exception waives surrender charges.
3. Request a direct rollover to an inherited IRA. Ask the insurance company to transfer the cash surrender value (or the death benefit if higher) directly to your inherited IRA custodian.
4. Allow extra time. Insurance company death claims often take 4–8 weeks longer than standard custodial transfers. Follow up every two weeks.

Timing matters: Some plans require beneficiaries to elect their distribution option within 60–90 days of the account owner's death. Missing this window may limit your choices. Contact the plan administrator within the first 30 days of death.

The 10-Year Rule and Your Distribution Deadline

Under the SECURE Act (IRC § 401(a)(9)(H), effective for deaths after December 31, 2019), most non-spouse beneficiaries of inherited 403(b) accounts must fully deplete the account by December 31 of the 10th year following the year of death.²

Example: Your mother, a high school teacher, dies in June 2025 with a $320,000 403(b) balance. You roll it to an inherited IRA. Your 10-year deadline is December 31, 2035. The entire balance — plus any growth — must be distributed by then.

Within the 10-year window, you choose the distribution pattern freely (subject to annual RMD rules, discussed below). You could take nothing in years 1–9 and the entire balance in year 10, take equal annual amounts, or any irregular schedule — as long as the account is empty by year 10.

Who is exempt from the 10-year rule?

Eligible Designated Beneficiaries (EDBs) can take distributions over their remaining life expectancy instead of being subject to the 10-year deadline. EDB categories are the same for 403(b)s as for IRAs:

• Surviving spouse
• Minor child of the deceased account owner (10-year rule kicks in after reaching the age of majority — age 21 under most interpretations)
• Disabled individuals (IRC § 72(m)(7))
• Chronically ill individuals
• Any beneficiary not more than 10 years younger than the account owner

See our complete 10-year rule guide for EDB details and the stretch distribution mechanics.

When Annual RMDs Are Required in Years 1–9

Many beneficiaries assume they can simply wait until year 10 and take one large distribution. This is wrong for a significant share of inherited 403(b) accounts. IRS final regulations (T.D. 10001, July 2024) clarified the rule:³

What is the Required Beginning Date for a 403(b)?

Under SECURE 2.0 (§ 107), the Required Beginning Date is April 1 of the calendar year following the year the account owner reaches:⁴

• Age 73 — if born between January 1, 1951 and December 31, 1959
• Age 75 — if born on or after January 1, 1960

Example: Your aunt, a retired hospital administrator born in 1956, dies at age 69 in 2025. Her RBD would have been April 1, 2030 (the year after she turned 73). Since she died before her RBD, no annual RMDs are required — you can defer all distributions until December 31, 2035, the last day of your 10-year window.

Contrast: Your father, a retired university professor born in 1947, dies at age 78 in 2025. He passed his RBD (age 73) in 2020 and had already started RMDs. Since he died after his RBD, you must take annual RMDs in years 1–9 of your 10-year window. Skipping even one annual RMD triggers a 25% excise tax on the missed amount (reduced to 10% if corrected promptly per SECURE 2.0).

Inherited Roth 403(b): Same Clock, No Tax

If you inherited a Roth 403(b), the 10-year rule applies — but distributions come out federal-income-tax-free when qualified. A distribution from an inherited Roth 403(b) is "qualified" (tax-free) when the original account was established at least 5 years before the distribution is taken.

For most beneficiaries inheriting from a parent or senior colleague who had a Roth 403(b) for years, the 5-year clock is already satisfied. You must still empty the account within 10 years — but all distributions are tax-free.

One caution: if the Roth 403(b) was opened very recently before the account owner died, earnings may not yet be "qualified." Confirm the account opening date with the plan administrator. In practice this affects very few beneficiaries — it only matters if the plan was opened in the last few years before death.

Church Plans and Non-ERISA 403(b)s

Not all 403(b) plans are subject to ERISA. Church plans — offered by religious organizations, church-affiliated hospitals and schools — are exempt from ERISA's Title I requirements under IRC § 414(e). Government employer plans (public school districts, state universities) are similarly ERISA-exempt.

What this means for beneficiaries:

• Fewer federal beneficiary protections. ERISA requires that a surviving spouse is the default beneficiary unless the spouse waives it in writing. Non-ERISA plans have no such requirement — the plan document governs, and the designated beneficiary on file (even if outdated) controls. This is why it's critical to request a copy of the beneficiary designation from the plan or insurance company immediately after the account owner's death.
• No PBGC backstop. Non-ERISA plans are not covered by the Pension Benefit Guaranty Corporation. For most 403(b) custodial accounts, this is irrelevant — the assets are held in your name, not the plan's. For annuity contracts, verify the insurance company's financial rating (AM Best A or higher is standard).
• Same IRC distribution rules. Despite ERISA exemption, church and governmental 403(b) plans are still subject to IRC § 401(a)(9) — the 10-year rule and annual RMD requirements apply equally. Non-ERISA plans cannot offer beneficiaries worse distribution options than federal tax law requires.

The Lump Sum Option: Fast but Expensive

You can take the entire 403(b) balance as a lump sum. The full pre-tax amount is added to your ordinary income in the year received. For a $350,000 inherited 403(b) received by a single filer with $80,000 in other income, the combined $430,000 of taxable income in 2026 would look roughly like this:

2026 ordinary income brackets per IRS Rev. Proc. 2025-32. Single filer standard deduction $16,100 (2026) assumed already reflected in other income figure. Illustrative only.

Spreading the same $350,000 over 10 years at $35,000/year keeps most distributions in the 22% bracket — potentially saving $40,000–$70,000 in total federal income tax versus the lump sum, depending on your other income. The right answer depends on your specific bracket trajectory over the 10-year window, not just this year's income.

Additionally, plan administrators are required to withhold 20% for federal taxes on any direct distribution (IRC § 3405). If you receive a $350,000 check, the plan sends $70,000 directly to the IRS — and you cannot put that $70,000 back into an inherited IRA after the fact.

Action Steps for the First 60 Days

1. Identify the product type. Is this a custodial account (mutual funds) or an insurance annuity contract? Contact the plan administrator and ask — the answer determines who you deal with and what your options are.
2. Get the beneficiary designation on file. Request a copy immediately. For ERISA-exempt plans especially, there may be no automatic spouse protection — confirm who is named.
3. For annuity contracts: request the contract terms. Ask whether the death benefit exception waives surrender charges. Get this in writing before electing any distribution.
4. Contact the plan administrator (and insurance company if applicable) within 30 days. Ask for the plan's distribution election deadline and all available options. Don't miss this window.
5. Open an inherited IRA at a brokerage before initiating the transfer. Title it correctly as inherited/beneficiary IRA — never in your own name alone.
6. Initiate a direct trustee-to-trustee transfer. Confirm the check or wire goes to the new custodian, not to you. No 60-day rollovers for non-spouse beneficiaries.
7. Determine whether annual RMDs apply. Did the original owner die before or after their Required Beginning Date? This controls your year 1 obligation. See the RMD calculator to map your full 10-year schedule.
8. Do not commingle with your own retirement accounts. An inherited IRA must remain separate. Rolling an inherited account into your own IRA as a non-spouse is a prohibited transaction that triggers full immediate taxation of the entire account.

Talk to an inherited 403(b) specialist

An inherited 403(b) has more moving parts than a standard IRA — two product types, possible surrender charges, ERISA exemptions for church and government plans, and a 10-year distribution window that interacts with your tax bracket trajectory year by year. A fee-only inheritance specialist handles these situations regularly. They can assess the annuity contract terms, determine whether annual RMDs are required, model the optimal distribution schedule, and coordinate the direct rollover so it's executed correctly the first time.
