Most federal employees have access to a pension plan, but the type and amount depend on when you were hired and which agency employs you

Yes, federal government jobs typically include pension coverage. The vast majority of civilian federal employees participate in one of two retirement systems: the Federal Employees Retirement System (FERS) or the Civil Service Retirement System (CSRS). Which system covers you depends almost entirely on your hire date. If you were hired before 1984, you are almost certainly under CSRS. If you were hired in 1984 or later, you are under FERS. A small number of employees hired after 2013 fall into a modified FERS category with different contribution rates.

The key difference between these systems is how much you and your employer contribute, how your benefit is calculated, and what other retirement income you receive. CSRS is more generous to the employee but requires higher contributions. FERS is less generous upfront but includes a match to your own retirement savings, similar to a 401(k) match in the private sector. Both systems pay you a monthly pension for life once you meet the age and service requirements.

State and local government jobs are different. Some states run their own pension systems for state employees, some offer 401(k)-style plans instead, and some offer both. County and city workers may be covered by a county or municipal pension fund, a state system, or a hybrid plan. There is no single answer for non-federal government work.

Key Takeaways

  • Federal civilian employees hired before 1984 are covered by CSRS, which pays a pension based on your highest three years of salary and years of service, with no Social Security offset.
  • Federal employees hired in 1984 or later are covered by FERS, which combines a smaller pension, a Thrift Savings Plan match (similar to a 401(k) match), and Social Security may be able to access.
  • You must work at least five years as a federal employee to earn any pension benefit under either system.
  • State and local government pensions vary widely by employer and location; some states offer pensions, some offer only 401(k)-style plans, and some offer both.
  • Federal employees and some state and local workers do not pay Social Security taxes on their government wages, which affects their retirement income picture.

How CSRS pensions work

The Civil Service Retirement System covers federal employees hired before January 1, 1984. Under CSRS, your pension is calculated using a formula based on your length of service and your highest average salary over three consecutive years (usually your last three years of work).

The basic formula is: 1.5% × years of service × high-three average salary. So if you worked 30 years and your average salary in your highest three years was $80,000, your annual pension would be 1.5% × 30 × $80,000 = $36,000 per year for life. You receive this pension starting the month after you separate from federal service, as long as you meet the age and service requirements.

To receive a CSRS pension, you must have at least five years of creditable service. However, the amount you receive depends on your age when you leave. If you have 30 years of service, you can retire at any age. If you have 20 years of service, you must be at least age 50. If you have fewer than 20 years, you cannot receive a pension until age 62. CSRS employees do not pay Social Security taxes on their federal wages, and they do not receive Social Security benefits based on that work.

How FERS pensions work

The Federal Employees Retirement System covers federal employees hired on or after January 1, 1984. FERS is a three-part system: a basic pension, a Thrift Savings Plan (TSP) with employer match, and Social Security.

The FERS basic pension formula is: 1% × years of service × high-three average salary. This is smaller than CSRS because FERS employees also build Social Security credits and receive an employer match to their retirement savings. If you worked 30 years with a high-three average of $80,000, your FERS pension would be 1% × 30 × $80,000 = $24,000 per year. You also earn Social Security credits on your federal wages (though at a reduced rate due to the Government Pension Offset, explained below), and your employer contributes up to 5% of your salary to your TSP account if you contribute at least 3%.

FERS employees must have at least five years of service to earn a pension. The age requirements are: age 62 with five years of service, age 56 with 30 years of service, or age 50 with 20 years of service. These thresholds are slightly different from CSRS and have changed for employees hired after 2013.

The Thrift Savings Plan and employer match

FERS employees have access to the Thrift Savings Plan (TSP), a retirement savings account similar to a private-sector 401(k). You choose how much to contribute from your paycheck (up to annual IRS limits), and your employer matches a portion of your contributions. The federal government contributes 1% of your salary automatically, even if you do not contribute yourself. If you contribute 3% or more, the government matches your full contribution up to 5% of your salary.

This match is a significant part of FERS retirement income and is one reason the basic FERS pension is smaller than CSRS. Over a 30-year career, the employer match can grow to a substantial sum, especially if you invest it in the TSP's stock or bond funds. Unlike the pension, which is may provide, the TSP balance depends on how well your investments perform and how much you contribute.

CSRS employees do not have access to the TSP as part of their retirement benefit, though some agencies have offered limited TSP access to CSRS employees in recent years. Check with your agency's human resources office if you are under CSRS and want to know whether you can open a TSP account.

Social Security and the Government Pension Offset

FERS employees pay Social Security taxes on their federal wages and earn Social Security credits. When you retire, you will receive both your FERS pension and a Social Security benefit based on your federal earnings and any other covered work.

CSRS employees do not pay Social Security taxes on their federal wages and do not earn Social Security credits for that work. This means CSRS retirees do not receive a Social Security benefit based on their federal service. However, if a CSRS employee worked in other jobs covered by Social Security, they can claim a benefit based on that work.

There is a complication called the Government Pension Offset (GPO) that affects some FERS and CSRS retirees. If you receive a government pension and are also may be able to access for Social Security as a spouse or surviving spouse, the GPO reduces your spousal or survivor benefit by two-thirds of your government pension amount. This can significantly lower the total household income in some cases. The Windfall Elimination Provision (WEP) is a separate rule that may reduce your own Social Security benefit if you receive a government pension. Both rules are complex and depend on your specific situation.

State and local government pensions

State and local government workers do not have a single retirement system. Each state, county, and city sets its own rules. Some states offer defined-benefit pensions (similar to CSRS or FERS), some offer defined-contribution plans (similar to a 401(k)), and some offer both options or a hybrid.

For example, California's state employees are covered by CalPERS, a defined-benefit pension system. New York State employees are covered by the New York State and Local Retirement System. Texas state employees are covered by the Employees Retirement System of Texas. Each system has different contribution rates, benefit formulas, vesting periods, and age requirements. Some state systems are very generous; others are less so. Some are well-funded; others face long-term funding challenges.

If you work for a state or local government, your human resources or payroll office can tell you which retirement system covers you and what your benefits will be. You can also contact the system directly—most publish annual reports and benefit statements online. The National Association of State Retirement Administrators (NASRA) maintains a directory of state and local systems if you need to find the right contact.

Vesting, survivor benefits, and what happens if you leave early

Both CSRS and FERS require five years of service to earn any pension benefit. This is called the vesting period. If you leave federal service before five years, you do not receive a pension, though you can withdraw your own contributions to the TSP (FERS only) or your CSRS contributions.

If you leave after five years but before you reach the age and service requirements to receive a pension, you can leave your money in the system and claim your pension later, starting at age 62 (CSRS) or age 62 (FERS with five years of service). Your pension will be based on your salary and service at the time you left, not your salary at the time you claim it. This is called a deferred pension.

Both CSRS and FERS include survivor benefits. If you die while employed or after you retire, your spouse and children may receive monthly benefits. The amount depends on your years of service and salary. You can also elect to receive a reduced pension during your lifetime in exchange for a may provide benefit to your survivor after you die. These options are explained in detail when you are close to retirement.

Frequently Asked Questions

Can I lose my federal pension if I leave my job before retirement?

No. Once you have five years of service, your pension is vested and belongs to you. If you leave before you reach the age and service requirements to claim it, you can leave your money in the system and claim a deferred pension later, usually at age 62. Your pension amount is based on your salary and service at the time you left, not when you claim it.

Do federal employees pay into Social Security?

FERS employees pay Social Security taxes and earn Social Security credits on their federal wages. CSRS employees do not pay Social Security taxes on federal wages and do not earn credits for that work. If a CSRS employee worked in other jobs covered by Social Security, they can claim a benefit based on that work.

What is the difference between a pension and the Thrift Savings Plan?

A pension is a may provide monthly payment for life, based on a formula using your salary and years of service. The TSP is a savings account where you and your employer contribute money, and the balance grows based on your investment choices. FERS employees receive both. The pension provides income security; the TSP provides flexibility and can grow significantly if you invest wisely.

How much do federal employees contribute to their pension?

CSRS employees contribute 7% of their salary to the CSRS fund. FERS employees contribute 0.8% of their salary to the basic FERS pension and can contribute 3% to 10% of their salary to the TSP (the employer matches up to 5%). Contribution rates vary slightly for employees hired after 2013.

What happens to my pension if I move to a different federal agency?

Your service time counts toward your pension regardless of which federal agency employs you. If you work for the Department of Defense for 10 years and then the Department of Veterans Affairs for 15 years, your total service is 25 years, and your pension is based on that combined service. You do not start over when you change agencies.
