Pension Joint and Survivor Option 2026: 50/75/100% Reduction

What the law requires of a married participant

The rules below are in the Code and regulations we saved on October 27, 2026. Several differ from what common summaries say, so each row names its paragraph.

Source: 26 U.S.C. 417 (Cornell Legal Information Institute) and Treas. Reg. 1.401(a)-20 (eCFR), read and saved October 27, 2026.

A correction to the 90-day figure. The statute’s election period is 180 days, but Treas. Reg. 1.417(e)-1(b)(3)(i) in the eCFR still says the consent must be made “not more than 90 days before the annuity starting date”, and Q&A-10 of 1.401(a)-20 says a waiver “is only effective if it is made 90 days before the annuity starting date.” We follow the statute, since a regulation cannot shorten it, but the 180-day figure was not written into those paragraphs. Read the notice you receive for the dates your plan applies; the 30-day notice floor appears in both.

What a plan can charge: the actuarial-equivalence gap

Section 417 requires equal value, not a particular factor. Compare that with the lump sum, where 417(e)(3) fixes the interest rates and the mortality table: for a joint-and-survivor monthly pension the plan chooses its own assumptions and publishes its own factor table, so you cannot check it against a public number. Here is a benchmark.

We price the survivor benefit the way the Code prices a lump sum: the IRS 2027 unisex mortality table from Notice 2026-27 (the one for stability periods beginning in 2027), the August 2026 segment rates of 4.65%, 5.75% and 6.73% (first 5 years, next 15, then the rest), monthly payments in advance, the participant’s pension continuing at the full amount if the spouse dies first (no pop-up), and independent lives. The neutral factor is the single-life value divided by the value of the pension plus the survivor share of the value of the spouse’s payments after the participant’s death. It is a model, not a quote.

Our model: the reduction by age gap and survivor share

Participant age 65. Cells show the reduction from the single-life check and, in brackets, the monthly check per $1,000 of single-life pension.

Source: our arithmetic from IRS Notice 2026-27 (unisex table) and the IRS segment rates page, August 2026 row. The pension continues in full if the spouse dies first.

The last column is the chance, in the table’s own mortality, that the participant dies while the spouse is alive, which is the only case in which a survivor benefit is ever paid. At 65/65 it is exactly 50.0% because both lives use the same table; at a 10-year gap it is 76.7%. A spouse 10 years younger therefore costs 17.8% for a 100% survivor benefit against 11.8% at the same age, because the survivor stream is expected to last about 11.0 years on average per couple instead of 4.8.

Younger participants

Source: our arithmetic, same inputs.

In our model the reductions are smaller at 60 and 62 than at 65; at 60 with a spouse of 55 a 100% survivor benefit costs 11.5%. A plan with early-retirement subsidies can differ.

How much the inputs move it

Participant 65, spouse 62.

Source: our arithmetic; the male and female columns are the section 430 static tables printed beside the unisex column in IRS Notice 2026-27.

Two lessons. Interest rates matter less than ages: a full point on all three segment rates moves the 100% reduction by about 1.1 points. Who is the participant and who is the spouse matters more: with a husband of 65 and a wife of 62, the separate male and female columns raise the 100% reduction from 13.6% to 15.6%. Whether your plan uses a unisex table, its own table or older interest assumptions is the question to ask. The IRS table is the floor for lump sums; it is not a rule for these factors.

A second benchmark: PBGC’s 10%

PBGC publishes its maximum guarantee for two forms of annuity. We divided the two columns.

Source: PBGC, Maximum monthly guarantee tables for 2027, last updated October 19, 2026; the shares are our arithmetic. PBGC says the joint and 50% survivor amounts apply only if both spouses are the same age.

PBGC applies a flat 10% cut to a 50% survivor pension, against 6.2% in our same-age model at 65. The gap is a reminder that the factor is an assumption. It is not evidence that your plan charges 10%; ask for your plan’s table.

Pay for it, or self-insure?

The J&S election is a survivor policy whose premium is a lower monthly check for life. The alternative is to take the single-life amount and keep the difference. Take a 65-year-old with a spouse of 62 and a pension of $1,000 a month single-life. A 100% survivor option pays $863.68, so the premium is $136.32 a month. We save that each month at 4.96% (the 10-year Treasury par yield of October 22, 2026) and compare it, at the date the participant dies, with the capital that would buy the survivor’s $863.68 a month for the spouse’s life at the August 2026 segment rates.

Source: our arithmetic; before tax, fees and any raise, per $1,000 a month of single-life pension. Scale the dollars by your pension.

The savings catch up with the need if the participant dies at 87 (50.4% of 65-year-olds are alive then in the IRS table). Before that the household is short; after it, ahead. At 80 the savings are 42% of what the survivor would need. The test says nothing about the household’s other money. A reader with $250,000 or more elsewhere, a spouse with a pension or a large Social Security survivor benefit, or a survivor who could live on less may accept the shortfall; a household that an early death would push below its needs will not. Our guide to Social Security survivor benefits shows what the widow or widower would get from that side, and the widow’s tax penalty shows why the survivor’s net income falls by more than the pension alone.

Worked example (our arithmetic)

A participant, 65, is offered $3,000 a month single-life. The spouse is 62. With a 75% survivor option and our benchmark factor of 89.4%, the check would be $2,682.45; the spouse would receive $2,011.84 a month for life after the participant’s death; and the household gives up $317.55 a month, $3,811 a year, while both are alive. If the spouse dies first, that $3,811 a year was paid for nothing, unless the plan has a pop-up feature that restores the single-life amount. Ask whether it does, and what it costs.

Naming someone other than a spouse

A non-spouse beneficiary is limited by the minimum distribution incidental benefit (MDIB) rule once the participant reaches the required-distribution age. Table 1 in Treas. Reg. 1.401(a)(9)-6(b)(2)(iii) limits the survivor share:

Source: Treas. Reg. 1.401(a)(9)-6(b)(2)(iii), Table 1, saved October 27, 2026.

If the participant’s sole beneficiary is the spouse, the regulation says the payment to the spouse “would not violate the MDIB requirement if it were 100 percent of the annuity payment payable to the employee, regardless of the difference in the ages between the employee and the employee’s spouse.” The tables in section 1.401(a)(9)-9 are life-expectancy tables for required minimum distributions; the survivor-share cap for a pension is in -6.

Decision points

• Ask in writing for the single-life amount and the 50%, 75% and 100% amounts, the factors and the assumptions behind them, whether there is a pop-up, and the date by which you must elect.
• Check the dates. The election period ends on the annuity starting date; the plan’s notice should give the 30-day clock and any waiver.
• Spouse’s signature. To take any form other than a QJSA, the spouse’s consent must be written, witnessed by a plan representative or a notary public, and specific to the form and beneficiary; it binds that spouse only.
• Compare with your plan’s lump sum, if offered. Giving up the survivor annuity for a lump sum needs the same consent. Our pension lump sum guide has the minimum lump sums, and the annuity payout calculator models what buying a joint annuity yourself would cost. Delaying money into a QLAC is a separate tool.

What a reader can do with this

1. Take your plan’s 50%, 75% and 100% amounts and divide each by the single-life amount. Compare with the row for your age gap above; a much larger cut than our benchmark is a question for the plan.
2. Multiply the monthly reduction by 12 and compare it with the survivor income the household would need.
3. Use the self-insure table: the household needs to expect that the participant lives past the break-even age, or that the survivor needs less.
4. If you will give up the survivor annuity, plan the spouse’s signature and notary before the election window closes.

The reduction factors are set by your plan, not by the IRS.
