Pension lump sum vs. monthly payments

A traditional pension, also called a defined benefit plan, promises a monthly payment in retirement based on a formula, usually tied to pay and years of service. Some plans also let participants take the value of that benefit as a single lump sum. The Pension Benefit Guaranty Corporation (PBGC), the federal agency that insures private pensions, notes that an employer may ask for this choice at a job change, at retirement, or even after monthly payments have started. The decision is usually permanent.

How the monthly payment works

The monthly option is an annuity: a fixed payment for life. Plans typically offer several forms. PBGC's overview of benefit options describes the common ones:

• Straight-life annuity. Payments last for the retiree's lifetime and stop at death. Nothing goes to a survivor.
• Joint and survivor annuity. Payments continue for the retiree's life, and after the retiree's death a spouse or other beneficiary receives a set share for the rest of that person's life, commonly 50, 75 or 100 percent.
• Certain-and-continuous annuity. Payments last for life, and if the retiree dies within a set period, such as 10 years from the start, a beneficiary receives the payments for the remainder of that period.

The form that covers more, such as two lives instead of one, generally pays a smaller monthly amount.

Spousal protections

Federal law builds in a default for married participants. The IRS explains that a defined benefit plan generally must pay a qualified joint and survivor annuity to a married participant unless the participant and spouse consent in writing to a different form. The IRS page describes an exception for very small benefits. The survivor's payment must be at least 50% and no more than 100% of the amount paid during the participant's life, and the spouse's consent must be witnessed by a plan representative or a notary.

How a lump sum works

A lump sum is the plan's calculation of what the future monthly payments are worth today. The plan uses interest rate and life expectancy assumptions required by law, so the offer can change from year to year as interest rates change. In general, higher interest rates produce smaller lump sums, and lower rates produce larger ones.

Once paid, the money belongs to the recipient, along with the responsibility for investing it and making it last.

Comparing the tradeoffs

PBGC summarizes the benefits and risks of each path. The comparison below draws on its list.

A simple way to put the two offers side by side is to count years of payments. As a hypothetical example, suppose a plan offers either $1,500 a month for life or $270,000 today. The monthly option pays $18,000 a year, so the lump sum equals 15 years of payments, before considering any investment gain or loss on the lump sum and before taxes. On that simple count, someone who lives well beyond 15 years collects more in total payments from the monthly option, and someone who does not may collect less. This arithmetic is a starting point only and leaves out survivor benefits and inflation.

PBGC suggests weighing factors such as health (the participant's and the spouse's), other steady income such as Social Security, living expenses, debts, savings, and investment skill and how it may change with age.

Taxes on each option

Monthly pension payments are generally taxable as ordinary income in the year received. If the participant made after-tax contributions, part of each payment is not taxed. The IRS covers the details in Topic no. 410.

A lump sum paid directly to the participant is generally taxable all at once, and the IRS notes that mandatory withholding of 20% applies to most taxable lump sums paid to the recipient from an employer plan. A recipient under age 59½ may also owe the 10% additional tax on early distributions unless an exception applies.

A direct rollover avoids both the withholding and the immediate tax. The plan sends the money straight to a traditional IRA or another employer plan, and tax is postponed until it is withdrawn. The guide on how a 401(k) rollover works explains direct and indirect rollovers.

What protects a pension

Some people consider a lump sum out of concern about the employer's finances. When PBGC becomes trustee of an insured single-employer plan, it pays benefits up to limits set by law.

The limit generally depends on the year the plan ends and the age at which benefits begin. PBGC's maximum monthly guarantee tables show, for a 65-year-old receiving a straight-life annuity, a maximum of $7,789.77 a month for 2026 and $8,113.64 a month for 2027, with lower amounts at younger ages and for forms with survivor benefits. PBGC states that most benefits in the plans it takes over are below the maximum. Separate guarantees apply to multiemployer plans.

Once money leaves the plan as a lump sum, PBGC coverage no longer applies to it.

Questions worth asking the plan

• Which payment forms are available, and what is the monthly amount for each?
• Can part of the benefit be taken each way? PBGC notes that some plans allow this.
• Does the monthly benefit include any cost-of-living adjustment?
• What is the deadline for the election, and can it be changed afterward?
• If the lump sum is taken, can it be sent as a direct rollover?
