No, employers are not required to offer a pension. Federal law does not force any private company to sponsor a pension or any other retirement plan, and as of March 2025 only 14 percent of private-industry workers had access to a traditional pension, while 70 percent had access to a defined contribution plan like a 401(k).1Bureau of Labor Statistics. Employee Benefits in the United States Summary Whether you have one depends on your industry, your employer’s size, and whether a union bargained for it. A handful of states now require employers to give workers access to a retirement savings account, but that is not the same as a pension.
What Federal Law Actually Requires
The Employee Retirement Income Security Act, known as ERISA, is the main federal law covering workplace retirement plans. It regulates plans that already exist. It does not require any private employer to create one.2Office of the Law Revision Counsel. 29 U.S.C. 1001 – Congressional Findings and Declaration of Policy A business can legally operate without offering retirement benefits of any kind. If an employer does choose to sponsor a plan, ERISA then imposes rules on funding, reporting, fiduciary duties, and participant rights.
ERISA also does not cover every employer. Government plans and most church plans are exempt.3Office of the Law Revision Counsel. 29 U.S.C. 1003 – Coverage Public-sector pensions for teachers, police officers, and other government employees are governed by state or federal law instead, which is why the rules and benefit levels vary from one public employer to another.
State Retirement Savings Mandates
Where the federal government has stayed out, a growing number of states have stepped in. As of early 2026, roughly 20 states have enacted laws requiring certain private employers to provide access to a retirement savings program. Most are auto-IRA programs: if an employer does not already offer a qualified plan, it must automatically enroll workers into a state-facilitated individual retirement account funded through payroll deductions. These programs typically apply to businesses with a minimum number of employees, often five or more.
A state-mandated auto-IRA is not a pension. The employer does not contribute money and does not guarantee any payout. A percentage of your wages is deducted and deposited into an IRA unless you opt out. Penalties for employers that fail to register range from roughly $20 to $750 per employee depending on the state. These programs widen access to a savings vehicle, but the entire financial burden and investment risk sit with the worker.
Pensions vs. 401(k) Plans
A traditional pension is a defined benefit plan. The employer promises a specific monthly payment for the rest of your life after you retire, calculated by a formula based on your salary and years of service. The employer bears the investment risk and must keep the fund adequately funded to meet those promises.
A 401(k) is a defined contribution plan. You contribute money from your paycheck, your employer may match some of it, and the balance rises or falls with the market. There is no guaranteed monthly payment at retirement. What you get is whatever your account is worth.
The shift between the two has been dramatic. In the early 1980s, roughly half of private-sector workers with retirement coverage were in defined benefit plans. By 2025, that figure had fallen to 14 percent in private industry.1Bureau of Labor Statistics. Employee Benefits in the United States Summary Employers moved away from pensions because managing a pension fund carries long-term financial risk, requires actuarial oversight, and creates liabilities that stay on the company’s books for decades.
Where Pensions Still Exist
Public-sector employment is the most reliable place to find a traditional pension. Federal civilian workers, state employees, local government staff, public school teachers, law enforcement officers, and firefighters commonly receive defined benefit plans through large public retirement systems governed by state or federal law rather than ERISA.
In the private sector, pensions survive mainly in heavily unionized industries: telecommunications, utilities, manufacturing, and the building trades. Many of these are multi-employer plans, where several companies in the same industry contribute to a shared fund. That structure lets workers carry pension credits between employers within the same trade or union.
Outside government and unionized trades, traditional pensions are rare. Technology companies, retailers, and service-sector employers almost exclusively offer 401(k)-type plans. If a guaranteed retirement income matters to you, focusing your job search on public-sector positions or union-covered trades significantly raises your chances of finding one.
If Your Employer Does Offer a Pension
Once a plan exists, ERISA sets minimum standards the employer has to meet. A plan generally cannot exclude a worker who has reached age 21 and completed one year of service, meaning any 12-month period in which you work at least 1,000 hours.4Office of the Law Revision Counsel. 26 U.S.C. 410 – Minimum Participation Standards Once you clear both thresholds, the plan must let you start accumulating benefits.
Vesting
Vesting is your right to keep the pension benefits your employer has funded on your behalf. You may participate for years before those benefits are permanently yours. Federal law caps how long an employer can make you wait.5Office of the Law Revision Counsel. 29 U.S.C. 1053 – Minimum Vesting Standards Plans typically use one of two schedules:
- Five-year cliff vesting. You have no ownership of employer-funded benefits until you complete five years of service, at which point you become 100 percent vested at once.
- Three-to-seven-year graded vesting. Ownership increases gradually: 20 percent after three years, 40 percent after four, 60 percent after five, 80 percent after six, and 100 percent after seven or more.
If you leave before fully vesting, you forfeit the unvested portion of your employer-funded benefit. Contributions you made from your own wages, however, are always 100 percent yours. Leaving a job one year short of full vesting can mean losing a significant chunk of your expected retirement income, so it pays to know exactly where you stand.
Spousal Survivor Benefits
Federal law requires most pension plans to protect your spouse. If you are vested and die before your payments begin, your surviving spouse is entitled to a qualified preretirement survivor annuity, an ongoing payment for the rest of their life based on the pension you had earned.6Office of the Law Revision Counsel. 29 U.S.C. 1055 – Requirement of Joint and Survivor Annuity and Preretirement Survivor Annuity Once you retire, benefits are paid by default as a joint and survivor annuity, meaning your spouse continues receiving payments after your death, typically at a reduced rate.
You can choose a different payment form, such as a higher monthly amount during your lifetime only, but your spouse must consent to the waiver in writing, witnessed by a plan representative or notary public.6Office of the Law Revision Counsel. 29 U.S.C. 1055 – Requirement of Joint and Survivor Annuity and Preretirement Survivor Annuity A plan may require that you and your spouse were married for at least one year for the survivor benefit to apply.
If a Private Pension Plan Fails
If your employer’s pension fund runs out of money or the company goes under, the Pension Benefit Guaranty Corporation steps in. The PBGC insures most private-sector defined benefit plans, covering single-employer plans and multi-employer plans through separate insurance programs.7Pension Benefit Guaranty Corporation. PBGC Pension Insurance Coverage Public-sector plans and church plans are not covered.
When the PBGC takes over a failed plan, it continues paying benefits up to a legal maximum. For 2026, the maximum guaranteed monthly payment for someone retiring at age 65 from a single-employer plan is $7,789.77 under a straight-life annuity.8Pension Benefit Guaranty Corporation. Maximum Monthly Guarantee Tables The cap is lower if you retire before 65 and higher if you retire later. If your promised pension was below this limit, you should receive the full amount. If it exceeded the cap, your benefit may be reduced.
Filing for bankruptcy does not automatically end a pension plan. Termination is a separate legal event.9Pension Benefit Guaranty Corporation. Understanding Your Pension and PBGC Coverage In a standard termination, the employer can only end the plan after showing the PBGC that the fund has enough assets to pay all benefits owed, and participants receive their full benefits. In a distress termination, the plan is underfunded and the employer proves it cannot stay in business unless the plan ends; the PBGC then takes over as trustee and pays benefits up to the guaranteed limits. If you are already receiving payments when the PBGC steps in, payments continue without interruption, though they may be adjusted to reflect the caps.
Getting Plan Information and Challenging a Denial
If your employer offers a pension or other retirement plan, ERISA guarantees your right to detailed information about how it works. Your employer must provide a Summary Plan Description, a plain-language document covering benefits, participation rules, vesting, and claims procedures, within 90 days of the date you become a participant.10Office of the Law Revision Counsel. 29 U.S.C. 1024 – Filing With Secretary and Furnishing Information
If you think your benefits have been calculated incorrectly or your plan is being mismanaged, start with the Summary Plan Description and the plan administrator. If a claim for benefits is denied, you have 60 days from the written denial to file a formal appeal through the plan’s internal process.11U.S. Department of Labor.
