When your employer terminates a defined benefit pension, a pension plan termination lump sum is the single payment that represents the present value of the lifetime annuity you had been earning. The plan converts your future monthly checks into one dollar figure using IRS-published interest rates and a required mortality table, and you generally choose between taking that lump sum or keeping the annuity. The number can swing significantly depending on the month your distribution is calculated, and the decision is permanent once made.
How the Lump Sum Is Calculated
Federal law sets a floor for the calculation through minimum present value rules. Two actuarial inputs do almost all the work: an interest rate and a mortality table.
Segment Rates
The IRS publishes three segment rates each month, and plans use them as discount rates on your projected future payments. Each rate applies to a different time horizon. Your plan document specifies a stability period (a month, quarter, or year) during which the rates stay fixed, and a lookback month that tells the actuary which of the five months before the stability period supplies the rate. You do not get to pick either one.
As of early 2026, the three segment rates for minimum present value calculations run roughly from 4% on the short end to over 6% on the long end. These rates move with bond markets. When rates rise, lump sums shrink; when rates fall, lump sums grow. A one-percentage-point increase across all three segments can reduce a lump sum by roughly 20% or more for a participant in their early 50s, with a smaller effect for participants closer to retirement age.
The intuition is simple. A dollar you would receive 20 years from now is worth less than a dollar today because today’s dollar could be invested. The higher the rate the plan assumes on that invested dollar, the less it needs to hand you now to replicate the annuity. Low rates mean the plan has to set aside more, so your check is larger.
Mortality Table
The mortality table estimates how long you would live and therefore how many annuity payments the lump sum has to replace. For distributions with annuity starting dates in stability periods beginning in 2026, the IRS requires a static unisex mortality table blending 50% male and 50% female rates. A longer projected life expectancy means more payments to replace, which increases the payout.
Anti-Cutback Floor
Many plans use their own internal interest and mortality assumptions in addition to the IRS-required factors. Federal law prohibits any amendment that reduces benefits you have already earned. In practice, your lump sum must be the larger of the amount calculated using the plan’s own factors or the amount calculated using the IRS segment rates and mortality table. You get whichever method produces the bigger check.
Taxes and Rollovers
What you do with the money when it arrives determines whether you owe tax now, later, or with a penalty attached.
Direct Rollover
A direct rollover sends the lump sum straight from the plan’s trustee to the trustee of an IRA or your new employer’s plan. The money never passes through your hands, nothing is withheld, and you owe no tax until you eventually draw on the IRA in retirement. For most people, this is the right move. The administrator reports the transfer on Form 1099-R, but the taxable amount shown will be zero.
The 20% Withholding Trap
If the distribution is paid to you instead of rolled over directly, the plan must withhold 20% for federal income tax. You have 60 days to deposit the full original amount into an IRA or qualified plan to avoid tax on the distribution, but to complete that rollover you have to make up the missing 20% out of pocket.
An example makes the arithmetic concrete. Your lump sum is $200,000. The plan sends you $160,000. To finish the rollover you need to deposit $200,000 into your IRA within 60 days. If you deposit only the $160,000 you actually received, the IRS treats the $40,000 shortfall as a taxable distribution. If you are under 59½, you also owe a 10% early withdrawal penalty on that $40,000. You will get the withheld $40,000 back as a credit when you file your return, but you created a taxable event you did not intend. The IRS can waive the 60-day deadline in hardship situations like natural disasters, but do not count on it.
Early Withdrawal Penalty and the Age 55 Rule
A taxable distribution taken before age 59½ generally triggers a 10% additional tax on top of regular income tax. Several exceptions apply to pension distributions:
- Separation from service during or after the year you turned 55 (age 50 for public safety employees of state or local governments). This exception only works for distributions paid directly from the employer plan. Roll the money into an IRA first and you lose it.
- Substantially equal periodic payments calculated under one of three IRS-approved methods, continued for at least five years or until you turn 59½, whichever is later. Modifying the schedule early triggers the penalty retroactively, plus interest.
- Total and permanent disability, or payment to a beneficiary after the participant’s death.
One nuance that catches people off guard: a plan termination is not automatically a separation from service. If your employer terminates the pension but you keep working there, the age 55 exception will not apply to your termination distribution. You would need to have actually left the company during or after the year you turned 55.
The Election Paperwork
Once termination is underway, the plan administrator sends you an explanation of your distribution options, sometimes called a Section 402(f) notice or an annuity commencement notice. It lays out the lump sum amount, the equivalent monthly annuity, and the tax consequences of each option. Federal regulations require that notice to arrive at least 30 days before the distribution date and no more than 90 days before. You can waive the 30-day waiting period in writing if you want your money faster.
The plan sets a deadline for returning your election form. If you want the lump sum, you specify whether it is paid to you directly or sent as a direct rollover to an IRA or qualified plan. The direct rollover avoids the 20% withholding, which is why it is the default choice for most people.
Spousal Consent
If you are married, the law assumes your spouse is entitled to a qualified joint and survivor annuity. Electing a lump sum instead requires your spouse’s written consent, witnessed by either a plan representative or a notary public. The consent has to identify the specific form of payment being elected, and your spouse must acknowledge giving up the survivor annuity. If your spouse refuses, you take the annuity.
Small Balances
The SECURE 2.0 Act raised the mandatory cash-out limit from $5,000 to $7,000 for distributions after December 31, 2023, though sponsors adopt the higher limit at their option. If the present value of your vested benefit is at or below the plan’s threshold, the plan can pay it out as a lump sum without your election and without spousal consent. Above the threshold, the plan needs your written consent before distributing anything.
If the Plan Is Underfunded
Everything above assumes a standard termination, where the plan holds enough assets to cover every dollar owed. If the sponsoring employer is in severe financial trouble and the plan cannot pay all promised benefits, the termination is a distress termination and the PBGC steps in as trustee. The PBGC guarantees benefits only up to a statutory monthly maximum that varies by age. For 2026, the cap for a 65-year-old on a straight-life annuity is $7,789.77 per month; at age 55, the cap is $3,505.40 per month. Anything above the cap is lost.
The PBGC does not generally pay lump sums in distress terminations; benefits are typically paid as monthly annuities. If your plan is heading into PBGC trusteeship, the lump sum question may not be yours to answer.
Lump Sum or Keep the Annuity
There is no universal right answer, but a few factors push decisively.
The annuity cannot run out. However long you live, the checks keep coming. Live well past your actuarial life expectancy and the annuity pays far more than the lump sum could reasonably generate. It also removes investment risk and requires no financial management on your part.
The lump sum gives you control. You can invest it, leave it to heirs, or handle large one-time expenses that a monthly check cannot cover. In exchange, you take on investment risk and the risk of outliving the money. If you earn less than the plan’s assumed discount rate on the invested lump sum, you end up with less total income than the annuity would have provided. The higher the segment rates used in your calculation, the smaller the lump sum relative to the annuity, and the more the math favors keeping the annuity.
Health matters. A participant with a serious medical condition and shortened life expectancy may receive more total value from a lump sum than from an annuity that ends at death. Someone in excellent health with long-lived parents has the odds tilted toward the annuity. If Social Security and other guaranteed income already cover your basic expenses, the annuity’s insurance value is smaller and the lump sum’s flexibility is worth more.
Divorce and QDROs
If you are divorced or divorcing, pension benefits earned during the marriage are often divided through a Qualified Domestic Relations Order. A QDRO is a court order directing the plan to pay a portion of your benefit to your former spouse as the alternate payee. Without a valid QDRO on file, the plan pays according to its own terms regardless of what the divorce decree says. An alternate payee who is a former spouse pays tax on the distribution as though they were the participant; if the QDRO directs payment to a child or other dependent, the tax stays with you. A plan termination compresses the timeline, so getting the QDRO qualified by the plan before benefits are distributed becomes urgent.
If You Ignore the Notices
A terminated plan has to distribute everything and close. If you cannot be found or do not respond, the plan handles your money without you. Benefits at or below the cash-out threshold can be forced into an automatic rollover IRA in your name, with the administrator picking the provider and a default low-risk investment such as a money market or stable value fund. For larger benefits where the plan cannot locate you, the administrator will either buy an annuity from a private insurer in your name or transfer your funds to the PBGC’s missing participants program, which holds the money until you surface. Either way, you lose the choice between the lump sum and the annuity. Do not let inertia decide this for you.
