How a pension works
While you work, you earn credit under the plan’s formula, typically a percentage of your pay for each year of service, as in a traditional defined benefit plan. The credit becomes yours once you are vested. If you leave before retirement, a vested benefit usually waits in the plan, based on your pay and service when you left, until you reach its retirement age.
The plan pays in full at its normal retirement age, often 65, and many plans allow an earlier start at a reduced rate. The sponsor invests a pooled trust meant to cover everyone’s promised benefits, so you pick no investments and a market slump does not shrink your check. That is the core difference from a 401(k) or another defined contribution plan, where you own an account and carry the investment risk.
Pensions are now uncommon in private jobs. In March 2025 the Bureau of Labor Statistics found that 14% of private-industry workers had access to a defined benefit plan, against 70% with access to a defined contribution plan. Many public employees, such as teachers, police officers and firefighters, still earn one, sometimes in place of Social Security.
Pension payout options at retirement
When a pension starts, you usually choose how it is paid, and the choice is generally permanent. Each option trades a larger check now against protection for a spouse or heirs. For married participants in private plans, federal law makes a joint and survivor annuity the default: the survivor must receive between 50% and 100% of the amount paid during your life. Choosing an option without a survivor benefit requires your spouse’s written consent, witnessed by a notary or a plan representative.
- Single life annuity: the largest monthly check, which stops at your death.
- Joint and survivor annuity: a smaller check that continues to your spouse at 50%, 75% or 100%.
- Life with period certain: payments for life, plus a guaranteed minimum number of years for a beneficiary if you die early.
- Lump sum: if the plan offers one, the whole benefit paid at once, which you can roll into an IRA to keep tax deferral.
Is your pension safe if your employer fails?
The plan’s money sits in a trust separate from the employer’s own assets, so a bankruptcy does not by itself wipe out benefits you have earned. If a single-employer plan ends without enough money, the Pension Benefit Guaranty Corporation (PBGC), a federal agency, takes it over and pays benefits up to a legal maximum. For plans ending in 2026, that maximum is $7,789.77 a month for a straight life annuity starting at 65, and less for earlier starts or survivor forms. Benefit increases made in the five years before a plan ends may be only partly covered.
Multiemployer union plans sit in a separate PBGC program with a much smaller guarantee that is not indexed for inflation. Federal, state and local government plans and some church plans fall outside ERISA, the federal pension law, and are not insured by PBGC. Their security rests on the sponsoring government, the plan’s funding and state law, so read your plan’s funding reports.
How pension income is taxed
Pension payments are taxed as ordinary income. If you paid in after-tax dollars, part of each payment is a tax-free return of those contributions, figured under the IRS Simplified Method for pensions starting after November 18, 1996. You can have federal tax withheld by filing Form W-4P.
Payments before 59½ can also owe the 10% additional tax, but two exceptions cover most pension checks: lifetime payments that begin after you leave the employer, which count as substantially equal periodic payments, and payments after you leave in or after the year you turn 55, or 50 for many public-safety workers. The tax mostly reaches a lump sum cashed out early rather than rolled over.
A pension is not a wage, so it carries no Social Security or Medicare payroll tax and does not count toward the Social Security earnings test. States differ widely: some tax pensions fully, some exempt part of them, and some have no income tax.
Fitting a pension into your retirement plan
A pension works like a large, very conservative asset. Together with Social Security, it forms an income floor that arrives whatever markets do, so your savings have less to supply each year. That lowers the withdrawal rate your portfolio must sustain, or leaves room to delay Social Security.
Two details decide how much that floor is really worth. The first is inflation: some plans, especially public ones, raise payments with a cost-of-living adjustment, while many pay the same dollar amount for life, which steadily loses buying power. The second is the survivor: if the pension stops at the first death, the surviving spouse can lose that income just as single-filer tax brackets arrive, the widow’s penalty. Plan for the years after each spouse’s death, not just the first year of retirement.

The pension stands in for a sizable portfolio, but the $750,000 comparison assumes withdrawals that rise with prices. With no cost-of-living adjustment, this pension buys about 45% less after 20 years of 3% inflation, so compare pensions on their inflation terms, not only the starting check. Longevity risk works the other way: the longer you live, the more a lifetime pension pays.

Pension in MoneyWhatIf
Enter a pension you receive or have been quoted as its own income card, with a start date, a yearly change such as flat or tracking inflation, and any survivor share that continues after its owner’s death. If you are still earning it, turn on Work out the pension on the job to derive the benefit from service, a benefit percentage and final-average salary. Use one method, not both, or the pension counts twice. Pension income is charged income tax but no payroll tax, and survivor-option reductions are not priced, so enter the reduced benefit.
Common questions
Pension FAQs
How is a pension calculated?
Many traditional pensions multiply a benefit percentage, such as 1.5% or 2%, by your years of service and your average pay near the end of your career. At 1.5% for 30 years on $90,000 of average pay, that is $40,500 a year at the plan’s retirement age, before any reduction for an early start or a survivor option. The defined benefit plan page works through that formula, vesting and the 2026 benefit limit step by step.
What is the difference between a pension and a 401(k)?
A pension promises an income, usually for life, and the employer funds and invests the plan. A 401(k) promises nothing about the outcome: you and your employer contribute to an account in your name, and your balance depends on contributions, returns and fees. A 401(k) moves with you when you change jobs, while a pension rewards staying.
When can I start collecting my pension?
The full benefit starts at the plan’s normal retirement age, often 65. Many plans allow an earlier start with a reduction for each year before that age, and some public plans let you retire once your age plus years of service reach a set total, such as 80 or 85. You generally must leave the employer and apply. Your summary plan description or member handbook lists the ages and reductions.
Can I collect a pension and Social Security at the same time?
Yes. A pension from a job that paid Social Security tax never reduced your benefit. Pensions from work that did not pay Social Security tax, common for some teachers and public-safety workers, used to trigger the Windfall Elimination Provision and Government Pension Offset. The Social Security Fairness Act, signed January 5, 2025, ended both for benefits payable from January 2024, so those pensions no longer reduce Social Security.
What happens to my pension when I die?
That depends on the payout option you chose at retirement. A single life annuity stops at your death; a joint and survivor annuity keeps paying your spouse 50% to 100% for life; a period-certain option pays a beneficiary for any guaranteed years left. Some plans allow a non-spouse survivor, such as a child, at a reduced benefit. A lump sum rolled to an IRA passes by beneficiary designation instead.
Can my old state tax my pension if I move away?
Generally no. Federal law, 4 U.S.C. § 114, bars a state from taxing the retirement income of someone who is not a resident or domiciliary, and it covers pension payments from qualified and governmental plans. Your new state of residence may tax the pension under its own rules, so compare state income tax treatment of pensions before a move.
