Inherited Pension and Pension Rollover IRA: What Beneficiaries Need to Know in 2026

You just inherited a pension or an IRA that originally came from a pension rollover. The rules that apply — and the decisions you face — depend on two things: whether what you inherited is a defined benefit pension (a monthly annuity from an employer) or a rolled-over IRA, and whether you are the surviving spouse or a non-spouse beneficiary. These two variables determine everything from whether you can defer taxes to whether you must take annual withdrawals starting this year.

The Two Completely Different Scenarios

Before anything else, clarify which of these you're dealing with:

The two scenarios have almost nothing in common legally. Most beneficiaries mix them up because the original source was a pension — but once the pension was rolled to an IRA, it became an IRA governed by IRA rules, not ERISA pension rules.

Scenario 1: Inheriting a Defined Benefit Pension Still in the Plan

A defined benefit (DB) pension is an employer-sponsored plan that promises a monthly annuity based on years of service and salary. What you can inherit from it depends almost entirely on what election the retiree made — or did not make — before their death.

If the retiree elected a joint-and-survivor (J&S) annuity

You receive a monthly payment equal to the elected survivor percentage (50%, 75%, or 100% of the original annuity) for the rest of your life. This is the best-case scenario for surviving spouses: it requires no decision from you. The plan simply redirects payments at the reduced amount. ERISA §205 requires plans to default to at least a 50% joint-and-survivor annuity for married participants — the spouse must have signed a notarized waiver to override this, so a married retiree who elected life-only without the spouse's written consent may have given the surviving spouse a legal claim to a survivor annuity.

If the retiree elected life-only

Payments stop at death. Nothing passes to the surviving spouse or any beneficiary. This is the actuarial trade-off for the higher monthly income a life-only annuity provides. If you are discovering this after the fact, your only recourse is to verify that the required ERISA §205 spousal consent was properly obtained. If it was not — if your signature was forged, or if you were pressured into waiving without full disclosure — consult an ERISA attorney.

If the plan offers a lump sum that hasn't been taken yet

Some employer plans allow a surviving spouse to take a lump sum rather than the survivor annuity. If the plan is a large corporate plan and the participant died before distributions began, call the plan administrator's beneficiary services line within 60 days. Many offer a limited window. A direct rollover to your IRA avoids the 20% mandatory withholding trap. If you receive the check made out to you instead of your IRA, you have 60 days to deposit the full amount (including the 20% withheld, which you fund out of pocket and recover in a tax refund) or the withheld amount becomes taxable income.

Non-spouse beneficiaries of a DB pension

ERISA does not require plans to extend benefits to non-spouse beneficiaries beyond what the plan document allows. For most corporate DB pensions, if no spouse survivorship election applies, there is no inheritance for children or other relatives. Some plans provide a "period certain" option (e.g., payments guaranteed for 10 years even if the retiree dies) — non-spouse beneficiaries would then receive the remaining guaranteed payments. Non-spouse beneficiaries cannot roll DB pension payments to an IRA. The 60-day rollover rule does not apply to annuity payments from a pension plan to a non-spouse.

PBGC protection for inherited DB pension benefits

If you are inheriting a survivor annuity from a terminated corporate plan, PBGC coverage limits apply to your benefit too. The 2026 PBGC maximum is $7,789.77/month (straight-life at age 65); for a 50% J&S survivor annuity, the effective cap on the survivor's payment is lower because it reflects the joint-life actuarial adjustment. For details, see our PBGC Pension Guarantee guide.

Scenario 2: Inheriting an IRA That Came From a Pension Rollover

Once a pension lump sum was rolled to a traditional IRA, that money became a regular IRA subject to IRA inheritance rules. The pension origin is irrelevant. What matters is:

• Your relationship to the deceased (spouse vs. non-spouse)
• Whether the deceased had passed their Required Beginning Date (RBD) for RMDs
• Whether you qualify as an Eligible Designated Beneficiary (EDB)

Surviving Spouse: The Most Flexible Position

A surviving spouse has options no other beneficiary has. You face one primary decision:

Surviving spouse's RMD timing after rolling into own IRA

Once you roll the inherited IRA into your own IRA, your RMD start age is determined by your own birth year, not the deceased's. Under SECURE 2.0: age 73 if you were born 1951–1959; age 75 if you were born 1960 or later.¹ This is often the biggest benefit of the rollover: if the deceased was in their mid-to-late 70s and already taking RMDs, a surviving spouse in their 60s who rolls the account into their own IRA can potentially delay RMDs for a decade.

Non-Spouse Beneficiaries: The 10-Year Rule

If you are not the surviving spouse and you do not fall into one of the special Eligible Designated Beneficiary (EDB) categories, you are subject to the 10-year rule under IRC §401(a)(9)(H): you must empty the inherited IRA by December 31 of the 10th year following the year of death. There are no required distributions in years 1–9 if the account owner died before their RBD. But if the deceased died after their RBD, annual distributions are required in years 1–9.

The annual RMD trap: T.D. 10001

Treasury Decision 10001 (July 2024) finalized regulations confirming that when a non-EDB beneficiary inherits from an account owner who died on or after their RBD, annual RMDs are required in each of years 1–9 of the 10-year period — not just by the final year 10 deadline.² The annual RMD is calculated using the beneficiary's single life expectancy table divided by the beneficiary's remaining life expectancy factor, recalculated annually. Failure to take the annual RMD triggers a 25% excise tax on the shortfall (reduced to 10% if corrected within two years under SECURE 2.0).

Eligible Designated Beneficiaries (EDBs) — who gets different treatment

Under IRC §401(a)(9)(E)(ii), the following categories are EDBs and are not subject to the 10-year rule:³

Most adult children inheriting a pension rollover IRA from a parent fall into the 10-year rule, not the stretch. EDB status is determined at the time of inheritance — you cannot retroactively qualify by becoming disabled after inheriting.

Tax Planning Within the 10-Year Window

The 10-year rule is not purely bad news. It gives you flexibility on when within those 10 years you take distributions. Large inherited IRAs (from pension rollovers, $300K–$2M is common) benefit from strategic distribution planning:

• Front-load in low-income years. If years 1–3 after inheritance coincide with lower income (career transition, parental leave, early retirement), taking larger distributions in those years avoids stacking income into a higher bracket in the mandatory year 10.
• Smooth the distributions over 10 years. For a $600K IRA at 5% growth, equal annual distributions of roughly $75K (varying with growth) keep more of the distribution in the 22–24% range rather than pushing into 32%+ in a single year.
• Avoid the year-10 pile-up. Deferring all distributions to year 10 is tempting but typically produces the highest total tax burden. $600K in one year likely crosses into the 32% bracket and triggers IRMAA, while $60K/year over 10 years might not.
• Coordinate with your own Roth conversions. If you were planning Roth conversions from your own IRA, inherited IRA distributions count as ordinary income in the same tax year. A large inherited IRA distribution plus your own Roth conversion can stack unexpectedly.

Federal Employee Pensions: FERS and CSRS Death Benefits

For beneficiaries of federal employees, the rules differ from private-sector pensions:

FERS employee who died before retirement

The surviving spouse receives the Basic Employee Death Benefit (BEDB): a lump sum equal to 50% of the employee's final salary plus $43,800.53 (for deaths after December 1, 2025, indexed annually).⁴ A monthly survivor annuity may also apply (50% of computed FERS annuity as of date of death) if the employee had at least 18 months of federal civilian service. Children under 18 also receive a separate monthly benefit. These payments are taxable as ordinary income. The BEDB lump sum can be rolled over to an IRA if it qualifies as an eligible rollover distribution — contact OPM to confirm before taking the cash.

FERS retiree who elected survivor benefit

The surviving spouse receives 50% (full survivor benefit) or 25% (partial) of the retiree's FERS annuity. This is a DB pension survivor benefit — not rollable, but COLA-adjusted. See our FERS Retirement Guide for annuity calculation details.

Military survivor (SBP)

SBP provides 55% of the covered base pay to the surviving spouse, COLA-adjusted for life. The SBP-DIC offset was permanently eliminated in January 2023, so a surviving spouse can now receive full SBP plus full Dependency and Indemnity Compensation from the VA without offset. 2026 DIC rate: $1,699.00/month.⁵ SBP payments are taxable as ordinary income. Unlike a pension lump sum, there is no IRA rollover option — SBP is a monthly annuity only.

Union and Multiemployer Pension Survivors

Multiemployer (union) pensions are subject to the same ERISA §205 QPSA and J&S requirements as corporate single-employer plans. However, most multiemployer plans do not offer lump-sum options — survivor benefits are in the form of a reduced monthly annuity. The PBGC multiemployer guarantee formula is much lower than the single-employer cap: $35.75 per month times years of service, capped at $1,072.50 per month for 30 years of service, vs. the $7,789.77/month single-employer cap.⁶

State and Municipal Pension Survivors

State and municipal plans (CalPERS, TRS, NYSLRS, PERA, etc.) are exempt from ERISA but almost all have their own survivor benefit rules. Most offer a 50% survivor option at retirement; some offer pre-retirement death benefits similar to FERS BEDB. These plans rarely offer lump sums to non-spouse beneficiaries, and you generally cannot roll a state plan survivor annuity into an IRA. Contact the plan administrator or your state's retirement system for the specific rules in your case.

Beneficiary Checklist: What to Do in the First 90 Days

1. Identify exactly what you inherited. DB pension still in a plan, or a rolled IRA? Get statements from both the employer plan and any IRA custodians (Fidelity, Vanguard, Schwab, TIAA, etc.).
2. Contact the plan administrator within 60 days if this is a DB pension. Ask specifically: Is there a lump sum option? What survivor annuity is available? What is the election deadline?
3. For inherited IRAs: open a properly titled inherited IRA account at the custodian. Do NOT roll the money into your existing IRA unless you are the surviving spouse electing rollover treatment. Commingling inherited IRA money with your own IRA destroys its inherited status and triggers a full distribution event.
4. Determine if annual RMDs apply. Did the deceased pass their RBD (April 1 after turning 73 or 75)? If yes and you are a non-EDB beneficiary, calculate your year-1 RMD and take it by December 31.
5. Model your 10-year distribution plan. Use our federal income tax guide and bracket tables to estimate the tax cost of different distribution schedules.
6. Update your own beneficiary designations. Once you inherit an IRA, you should name your own beneficiaries on the inherited account. If you die during your 10-year distribution period, your beneficiaries generally must complete the original 10-year window — they don't get a new 10 years.
7. Consider IRMAA exposure. Large inherited IRA distributions can push your income into IRMAA territory, increasing Medicare Part B and Part D premiums two years after the distribution year. See our IRMAA guide for the 2026 bracket thresholds.
