Which inherited 403(b) options fit your family and retirement date?

The first 30 days with the plan administrator

Your plan administrator, not the hospital HR office, handles the beneficiary claim and usually asks for the death certificate, your Social Security number, a beneficiary claim form, and details for the receiving account. After the paperwork is complete, payout or transfer work commonly takes 2–6 weeks.

If this is you, run this checklist before choosing where the money goes:

• Are you named on the current beneficiary form?
• Are you a spouse or a non-spouse beneficiary?
• Had the owner reached RMD age, 73, or 75 for someone born in 1960 or later?
• Is the account pre-tax, Roth, or both?
• Are there co-beneficiaries, such as siblings?
• Did the owner already take this year's RMD?

What age changes a surviving spouse's choice?

A surviving spouse under 59½ often keeps the money as an inherited IRA first, because rolling it into an IRA in the spouse's own name can make withdrawals before 59½ subject to the 10% additional tax. The inherited account generally allows access at any age without that penalty, although ordinary income tax can still apply to pre-tax money.

A spouse in their 40s or 50s may leave the account inherited until 59½, then move it into their own IRA. That can preserve access now and delay the spouse's own RMD start. A sole-beneficiary spouse may also elect to be treated as the deceased spouse for RMD timing. Ask the plan administrator whether the plan offers that election.

How long does a non-spouse beneficiary have?

A non-spouse beneficiary generally has until December 31 of the 10th year following the owner's death to reduce the inherited account to $0. If the owner died before RMD age, no annual amount is generally required in years 1–9 under the 10-year rule; if the owner had reached RMD age, annual RMDs may also apply in those years.

The dates arrive in order. A qualified disclaimer must usually be completed within 9 months of death and before taking money. The owner's unpaid RMD is generally due by December 31 of the death year. Beneficiaries are determined by September 30 of the following year, and separate accounts for co-heirs should generally be established by December 31 of that following year. The final balance is due by December 31 of year 10.

A missed RMD can create a 25% excise tax on the shortfall, reduced to 10% when corrected within the IRS correction window. Ask your CPA to confirm the amount and correction process. The IRS has also issued transitional relief for some early years under the newer inherited-account rules, so a missed amount should not simply be ignored.

The inherited-account rules changed before your retirement window

For deaths before 2020, many named heirs could stretch withdrawals over their own life expectancy. Those older inherited accounts may keep that treatment. For deaths after 2019, most adult children face the 10-year payout instead, even if a parent's estate roadmap was written around lifetime withdrawals.

Later IRS regulations added annual RMDs in years 1–9 when the owner had already begun RMDs. The IRS waived some penalties during the first few years of the change. If the owner was already taking RMDs, have your CPA compare the account history with the current IRS rule before moving money.

Ingrid's 10-year window and 3 possible start dates

Ingrid is 46, single, and works as a travel nurse. She has $510K across 7 small employer plans and an IRA after signing contracts with 6 employers in 5 years. Her mother leaves her a $200K traditional 403(b). Her mother died at 70, before RMD age, so the main rule is a $0 balance by December 31 of year 10 (hypothetical, round numbers).

Ignoring investment growth, Ingrid can divide $200K by the years left in the window. Starting in year 1 means $20K annually for 10 years. Waiting 2 years means $25K annually for 8 years. Waiting 5 years means $40K annually for 5 years. Waiting until year 10 means $200K on one tax return.

Ingrid currently defers $14,500 from wages into a current 403(b). The IRS limit for 2026 is $24,500 across her employer plans, so raising her deferral shelters another $10K of wages each year. Her inherited withdrawal still counts as income, but the larger deferral offsets part of the income while she has a job offering a 403(b). The offset disappears during a gap between contracts.

The table's Year 1 row is the place to start if Ingrid expects steady wages; watch the final column grow as the withdrawal date slides. Once she turns 50, the IRS catch-up for these plans adds $8,000 of room in 2026, but the Year 6 choice still creates $22K of net added income annually after that catch-up ($40K minus $10K minus $8,000), compared with $10K when she starts now. Invested inherited money can fall below the amount inherited, so waiting can produce both a smaller account and a larger tax bill.

Ingrid's decision rule is practical: if you are a non-spouse heir with steady wages for the next 10 years, divide the balance by the years left and take at least that amount each year. A known low-income year, such as a gap between contracts, can justify taking more in that year. Midflorida Credit Union would put that annual amount and the December 31 deadline on one roadmap, rather than leaving the inherited account as a forgotten eighth account.

The deferral offset has a limit

Why waiting can backfire

How much of each withdrawal counts as income?

A pre-tax inherited 403(b) withdrawal generally counts fully as ordinary income and increases adjusted gross income and modified adjusted gross income; heirs do not face the 10% additional tax merely because they are under 59½. That income can affect other decisions, including the Roth IRA phase-out and later Medicare IRMAA.

For 2026, the IRS Roth IRA income phase-out for a single filer is $153K–$168K. Medicare Part B IRMAA is set by modified adjusted gross income from 2 years earlier: the 2026 premium uses 2024 income, and the single surcharge begins above $109K. An inherited withdrawal therefore only matters for Medicare if it lands within 2 years of enrollment. For Ingrid, Medicare starts at 65, so a withdrawal at 63 or later would raise a premium, while her 10-year window ends at 56.

Inherited Roth 403(b) money still follows the 10-year rule, but distributions can be tax-free once the original 5-year holding period is met. Ask the custodian how pre-tax and Roth sources are tracked. A calculator can show how several smaller withdrawals compare with one large withdrawal, but your CPA should check the actual return.

Income is more than the account balance

Roth money follows a different tax path

Which heirs can use a different payout rule?

Some eligible designated beneficiaries can still use life-expectancy payments instead of the standard adult-child approach. They include a surviving spouse, the owner's minor child until the child reaches 21, a disabled or chronically ill beneficiary, and an heir no more than 10 years younger than the owner, such as a sibling.

An estate or certain trusts may face a 5-year payout when the owner died before RMD age. That is not a do-it-yourself beneficiary claim. The trust document, beneficiary form, plan rules, and tax facts need review by an estate attorney and CPA.

The rule also changes when there are siblings. Separate inherited accounts can preserve each beneficiary's own timeline, but the setup deadline matters. Midflorida Credit Union keeps the account separate from your IRA or 403(b), with 1 or 2 funds and its own line on the roadmap.
