A pension in finance is an employer-sponsored retirement plan that sets aside money during your working years to provide income after you retire. The word covers two very different structures. A defined benefit plan promises you a specific monthly payment for life, calculated by a formula tied to your salary and years of service. A defined contribution plan, such as a 401(k), gives you an individual account whose value at retirement depends on how much you and your employer put in and how the investments perform. Only about 15 percent of private-sector workers still have access to a traditional defined benefit pension, so the first thing to know about your own pension is which kind it is.
Defined Benefit Plans
A defined benefit plan is what most people picture when they hear the word “pension.” The employer promises a specific monthly amount at retirement, calculated by a formula that typically factors in your salary history and your years with the company. A common formula multiplies years of service by a percentage of your average salary over your final working years. Someone with 30 years of service under a plan that credits 1.5 percent per year with a final average salary of $60,000 would receive $27,000 annually.
The employer carries all the risk. If the plan’s investments underperform, the company must contribute more to cover what was promised. The employer also absorbs longevity risk, meaning payments continue no matter how long you live. From your side as an employee, this is the most financially secure type of retirement plan because the benefit does not fluctuate with the stock market.
Defined Contribution Plans
A defined contribution plan, such as a 401(k) or 403(b), works like an individual investment account. You contribute from each paycheck, your employer may add a matching contribution, and the money is invested in funds you choose from the plan’s menu. Your retirement income depends entirely on how much goes in and how those investments perform.
For 2026, you can defer up to $24,500 of your salary into a 401(k), 403(b), or similar plan. If you are 50 or older, you can add an extra $8,000 in catch-up contributions, bringing the total to $32,500. Workers aged 60 through 63 get a higher catch-up limit of $11,250 under the SECURE 2.0 Act, allowing total deferrals of $35,750.1Internal Revenue Service. 401(k) Limit Increases to $24,500 for 2026, IRA Limit Increases to $7,500
The tradeoff is risk. You bear the investment risk; if your funds lose value, your retirement balance shrinks. You bear the longevity risk too, because you are responsible for making the balance last your entire retirement. Your employer’s obligation ends once the contribution hits your account.
Cash Balance Plans
A cash balance plan blends features of both structures. It is legally a defined benefit plan, so the employer carries the investment risk, but your benefit is expressed as a hypothetical account balance rather than a monthly payment formula. Each year the employer credits your account with a pay credit (often a percentage of your salary) and an interest credit tied to a fixed rate or an index such as the one-year Treasury bill rate.2U.S. Department of Labor. Cash Balance Pension Plans
“Hypothetical” matters here. The balance on your statement does not represent segregated assets or real investment gains allocated to you. It is a bookkeeping device the employer uses to calculate what you are owed. If the plan’s actual investments lose money, that is the employer’s problem; your credited balance keeps growing at the guaranteed rate.
When Your Benefit Becomes Yours: Vesting
Vesting determines how much of your employer-funded pension you keep if you leave the company. Your own contributions to a defined contribution plan are always 100 percent vested immediately, but employer contributions follow a schedule set by federal law. Leave before you are fully vested and you forfeit some or all of the employer-funded portion.
Defined benefit plans must use one of two schedules:3Office of the Law Revision Counsel. 26 USC 411 – Minimum Vesting Standards
- Five-year cliff vesting: you get nothing until you complete five years of service, then you are 100 percent vested all at once.
- Three-to-seven-year graded vesting: you vest 20 percent after three years, with another 20 percent each year until you reach 100 percent at seven years.
Defined contribution plans vest faster. Employer matching or profit-sharing contributions follow either a three-year cliff (0 percent until year three, then 100 percent) or a two-to-six-year graded schedule starting at 20 percent after two years and reaching 100 percent at six.
This is where people lose real money. If you are weighing a job change at four years of service under a five-year cliff, one more year can mean the difference between keeping your full accrued benefit and forfeiting it. Check your plan’s summary plan description for the exact schedule.
How You Get Paid at Retirement
When you reach retirement age, how you take the money is one of the highest-stakes financial decisions you will make. The two main options are a lifetime annuity and a lump sum.
Annuity Payments
An annuity converts your pension into a guaranteed monthly check for life. You can usually choose a single-life annuity that pays the maximum amount but stops at your death, or a joint-and-survivor annuity that continues paying a reduced amount to your spouse after your death.4Pension Benefit Guaranty Corporation. Annuity or Lump Sum If you are married, federal law requires the default payout to be a joint-and-survivor annuity unless both you and your spouse consent in writing to waive it. An annuity eliminates the risk of outliving your money, and taxes apply only to the payments you receive each year.
Lump-Sum Distributions
A lump sum gives you the entire present value of your future benefit in one payment. You get more control, but you take on all the investment and longevity risk yourself. The size is not fixed. Lump sums fluctuate with IRS-prescribed interest rates called segment rates: when interest rates rise, lump sums shrink, and when rates drop, lump sums grow.5Internal Revenue Service. Minimum Present Value Segment Rates
The tax consequences can be severe. The full amount counts as ordinary income in the year you receive it, which can push you into the highest brackets. To avoid that, execute a direct rollover into an IRA or another qualified retirement account. If the plan writes the check to you instead, it must withhold 20 percent for federal income tax.6Internal Revenue Service. Topic No. 412 – Lump-Sum Distributions You then have 60 days to deposit the full original amount, including replacing that withheld 20 percent from your own pocket, into a qualifying account. Miss the deadline and the entire distribution becomes taxable, plus you may owe a 10 percent early withdrawal penalty if you are under 59½.7Internal Revenue Service. Rollovers of Retirement Plan and IRA Distributions
Spousal and Survivor Protections
Federal law builds in protections for spouses that many people never learn about until something goes wrong. These apply automatically to defined benefit plans, money purchase plans, and certain other pension structures.
If You Die Before Retirement
A qualified pre-retirement survivor annuity (QPSA) pays your surviving spouse a lifetime income if you die before you start collecting benefits, as long as you were vested. Plans must provide this automatically to all married participants unless both spouses sign a written waiver witnessed by a plan representative or notary.8Internal Revenue Service. Retirement Topics – Qualified Pre-Retirement Survivor Annuity (QPSA) If the total value of your benefit is $5,000 or less, the plan can pay a lump sum instead without anyone’s consent.
If You Die After Retirement
A qualified joint and survivor annuity (QJSA) is the default payout form for married retirees. It pays you a monthly benefit while you are alive, then continues paying your surviving spouse between 50 and 100 percent of that amount for their lifetime. Your monthly check is smaller than a single-life annuity because the plan is covering two lifetimes, but your spouse is not left without income.
Divorce
Pension benefits earned during a marriage are often marital property. A court can divide them through a qualified domestic relations order (QDRO), which directs the plan to pay a portion of your benefit to a former spouse, child, or dependent. The QDRO must specify each alternate payee by name and state the exact amount or percentage. A former spouse receiving benefits under a QDRO pays taxes on those payments as if they were the plan participant themselves.9Internal Revenue Service. Retirement Topics – QDRO: Qualified Domestic Relations Order
Early Withdrawal Penalties and Exceptions
Taking money from a pension or retirement plan before age 59½ triggers a 10 percent additional tax on top of regular income tax. The penalty applies to both defined benefit and defined contribution distributions.10Internal Revenue Service. Retirement Topics – Exceptions to Tax on Early Distributions
Several exceptions reduce or eliminate it:
- Separation from service at 55 or older. If you leave your job during or after the year you turn 55, distributions from that employer’s qualified plan are penalty-free. This does not apply to IRAs.
- Public safety employees at 50. Firefighters, law enforcement officers, corrections officers, and certain other public safety workers in governmental plans can take penalty-free distributions starting at age 50.
- Governmental 457(b) plans. Distributions are not subject to the 10 percent penalty at all, regardless of age, unless the money was rolled in from another plan type.
The age-55 rule catches a lot of people off guard. It only applies to the plan of the employer you are separating from. Roll that money into an IRA first and the exception disappears, because the IRA follows its own rules, which generally require waiting until 59½.
Required Minimum Distributions
You cannot leave money in a tax-deferred retirement plan forever. Federal law requires you to start taking distributions from traditional IRAs, 401(k)s, and pension plans when you reach age 73. Your first distribution must be taken by April 1 of the year following the year you turn 73.11Internal Revenue Service. Retirement Topics – Required Minimum Distributions (RMDs)
One helpful exception applies to defined contribution plans. If you are still working at the company sponsoring the plan and you are not a 5 percent or greater owner, you can delay RMDs from that specific plan until you actually retire. A defined benefit pension already paying you a lifetime annuity generally satisfies the RMD requirement through those ongoing payments.
Federal Insurance If Your Pension Plan Fails
When a private-sector employer goes bankrupt or cannot fund its defined benefit pension, the Pension Benefit Guaranty Corporation (PBGC) steps in. The PBGC is a federal agency created by the Employee Retirement Income Security Act of 1974 (ERISA) that insures the basic benefits of roughly 31 million workers and retirees in private defined benefit plans.12U.S. Department of Labor. Types of Retirement Plans
The guarantee has limits. For 2026, a person retiring at age 65 under a straight-life annuity can receive a maximum guaranteed benefit of $7,789.77 per month, or about $93,477 per year. Retiring earlier reduces the guarantee and retiring later increases it: at age 55, the cap drops to $3,505.40 per month, while at age 75, it rises to $23,680.90. Joint-and-survivor annuities have lower caps because the benefit covers two lives.13Pension Benefit Guaranty Corporation. Maximum Monthly Guarantee Tables
Some benefits fall outside the guarantee entirely. The PBGC does not cover health or welfare benefits, severance pay, or benefit increases adopted within five years of the plan’s termination. If your employer sweetened the pension formula shortly before going under, you might not see the full increase.14Pension Benefit Guaranty Corporation. Guaranteed Benefits Defined contribution plans such as 401(k)s are not covered by the PBGC because there is no promised benefit to insure.
How Pension Income Is Taxed
Pension payments are generally taxed as ordinary income at the federal level. If you never made after-tax contributions to the plan, which is the case for most defined benefit participants, every dollar you receive is fully taxable. If you did make after-tax contributions, the portion of each payment that represents a return of those contributions comes back to you tax-free.15Internal Revenue Service. Topic No. 410 – Pensions and Annuities
State tax treatment varies widely. Some states exempt pension income entirely, others tax it fully, and many fall somewhere in between with partial exclusions. Check your state’s specific treatment before retirement to avoid a surprise on your first tax return as a retiree.
What Happens When You Change Jobs
Portability is one of the biggest practical differences between plan types. If you leave a job with a defined contribution plan, you can roll your 401(k) balance into your new employer’s plan or into an IRA. The money follows you.
Defined benefit pensions are far less portable. Your accrued benefit typically stays frozen with your former employer’s plan until you reach retirement age, at which point you can start collecting. In most cases, you cannot transfer years of service credit to a new employer’s pension. Some multiemployer plans and certain industry networks allow limited transfers, but those arrangements cover a small fraction of workers. The practical consequence is that switching jobs mid-career almost always means a smaller total pension than staying put, because the formula rewards long tenure and higher final salaries, both of which reset when you move.
If your vested defined benefit is small enough, the plan may offer a lump-sum cashout when you leave. Rolling that into an IRA preserves the tax deferral and gives you control over the investment. Taking it as cash triggers income tax and potentially the 10 percent early withdrawal penalty if you are under 59½.
