A pension, in finance, is an employer-sponsored retirement plan that provides income after you stop working. The term covers two very different structures. A defined benefit plan promises you a specific monthly payment for life, calculated by a formula. A defined contribution plan, such as a 401(k), builds a retirement balance from contributions and investment returns, with no guaranteed payout. Only about 15 percent of private-sector workers still have access to a traditional defined benefit pension, so the first thing to figure out is which type you actually have.
Defined Benefit Plans
A defined benefit plan is what most people picture when they hear the word “pension.” Your employer promises to pay you a specific monthly amount when you retire, calculated by a formula that typically factors in your salary history and how long you worked for the company. A common formula multiplies your years of service by a percentage of your average salary over the last few years of your career. 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 bears all the investment risk. If the plan’s portfolio underperforms, the company must contribute more money to cover what was promised. The employer also absorbs longevity risk: payments continue no matter how long you live. From the employee’s side, this is the most financially secure type of retirement plan because the benefit amount 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 a portion of each paycheck, your employer may add a matching contribution, and the money gets invested in funds you choose from a menu the plan offers. Your retirement income depends entirely on how much you and your employer contribute 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’re 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 changes made by 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 fundamental tradeoff is risk. You bear the investment risk: if your funds lose value, your retirement balance shrinks. You also bear longevity risk, because you’re responsible for making that balance last your entire retirement. Your employer’s obligation ends once the contributions hit your account.
Cash Balance Plans
A cash balance plan blends features of both structures. It’s 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 like the one-year Treasury bill rate.2U.S. Department of Labor. Cash Balance Pension Plans
The word “hypothetical” matters. The balance on your statement does not represent segregated assets or real investment gains allocated to you. It’s a bookkeeping device the employer uses to calculate what you’re owed. If the plan’s actual investments lose money, your credited balance still grows at the guaranteed rate. Many large employers that moved away from traditional pension formulas in recent decades switched to cash balance designs because they’re easier for employees to understand while still shifting investment risk to the company.
When Your Pension Benefit Becomes Yours: Vesting
Vesting determines how much of your employer-funded pension benefit you’re entitled to 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. Walk away before you’re fully vested and you forfeit some or all of the employer-funded portion.
For defined benefit plans, federal law gives employers two options:3Office of the Law Revision Counsel. 26 USC 411 – Minimum Vesting Standards
- Five-year cliff vesting: nothing until you complete five years of service, then 100 percent vested all at once.
- Three-to-seven-year graded vesting: 20 percent vested after three years, with an additional 20 percent each year until 100 percent at seven years.
Defined contribution plans have a slightly faster schedule. Employer matching or profit-sharing contributions must follow either a three-year cliff (0 percent until year three, then 100 percent) or a two-to-six-year graded schedule that starts at 20 percent after two years and reaches 100 percent after six.
This is where people lose real money. If you’re considering a job change at four years of service under a five-year cliff schedule, one more year could mean the difference between keeping your entire accrued benefit and forfeiting it completely. Check your plan’s summary plan description for the exact schedule your employer uses.
How You Get Paid at Retirement
When you reach retirement age, how you take your pension is one of the highest-stakes financial decisions you’ll make. The two main options are a lifetime annuity and a lump-sum distribution.
Annuity Payments
The annuity converts your pension into a guaranteed monthly check for life. You can typically choose a single-life annuity that pays the maximum amount but stops when you die, 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’re 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. The annuity eliminates the risk of outliving your money. 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. This hands you more control, but you take on all the investment and longevity risk yourself. The size of a lump sum is not fixed. It fluctuates with IRS-prescribed interest rates called segment rates. When interest rates rise, lump sums shrink because a smaller amount of money today can theoretically grow to cover the same future payments. When rates drop, lump sums get larger.5Internal Revenue Service. Minimum Present Value Segment Rates
Taxes on a lump sum can be severe. The full amount counts as ordinary income in the year you receive it, which can push you into the highest tax brackets. To avoid that, you need to 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’re under 59½.7Internal Revenue Service. Rollovers of Retirement Plan and IRA Distributions
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.8Internal 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.
Early Withdrawal Penalties
Taking money from a pension or retirement plan before age 59½ triggers a 10 percent additional tax on top of regular income tax. It applies to both defined benefit and defined contribution distributions.9Internal Revenue Service. Retirement Topics – Exceptions to Tax on Early Distributions Several exceptions reduce or eliminate the penalty:
- 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’re actually separating from. Roll that money into an IRA first and the exception disappears; the IRA follows its own rules, which generally require waiting until 59½.
Required Minimum Distributions
You can’t 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 73.10Internal Revenue Service. Retirement Topics – Required Minimum Distributions (RMDs) If you’re still working at the company sponsoring a defined contribution plan and you’re 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.
Spousal and Survivor Protections
Federal law builds in protections for spouses that many people don’t 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, as long as you were vested. Plans must provide this benefit automatically to all married participants unless both spouses sign a written waiver witnessed by a plan representative or notary.11Internal 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, the default payout form for married retirees is a qualified joint and survivor annuity (QJSA). It pays you a monthly benefit while you’re 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.
Pension benefits earned during a marriage are often considered 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. A former spouse who receives benefits under a QDRO reports and pays taxes on those payments as if they were the plan participant.12Internal Revenue Service. Retirement Topics – QDRO: Qualified Domestic Relations Order
What Happens If Your Employer Can’t Pay
When a private-sector employer goes bankrupt or can’t 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.13U.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, retiring later increases it. At age 55 the cap drops to $3,505.40 per month; at age 75, it rises to $23,680.90. Joint-and-survivor annuities have lower caps because the benefit covers two lives.14Pension Benefit Guaranty Corporation. Maximum Monthly Guarantee Tables Certain benefits fall outside the guarantee entirely: health or welfare benefits, severance pay, and benefit increases adopted within five years of the plan’s termination.15Pension Benefit Guaranty Corporation. Guaranteed Benefits
Defined contribution plans like 401(k)s are not covered by the PBGC because there’s no promised benefit to insure. Your 401(k) balance is what it is, and no federal agency backstops it.
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 industry-specific networks allow limited transfers, but these 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’re under 59½.
