If you work for the government, in some way your retirement is already being planned for you. Federal workers, teachers, police officers, and city staff all fall under some kind of retirement system. Most people don’t think much about it until they’re a few years away from retiring, and by then there’s a lot of catching up to do. It helps to get familiar with the basics early, even if retirement still feels far away.
Not every plan works the same way, and that’s where things get a little tricky. Some pay you a fixed check every month for life, no matter what happens in the stock market. Others build up a savings account that grows while you work, and the final amount depends on how much goes in and how the investments perform. A few plans try to do both at once, blending a guaranteed piece with a savings piece. The type of plan you have changes how you should think about saving, when you can retire, and what your monthly income will actually look like.
This can get confusing fast, especially with all the short forms like FERS, TSP, 403(b), and 457(b) floating around. Each one has its own rules for contributions, vesting, and withdrawals, and mixing them up can lead to bad assumptions about your own retirement. So let’s slow down and go through each type of plan, how it works, and what you should know before you retire.
What Are Government Retirement Plans?
A government retirement plan is a retirement program sponsored by a federal, state, or local public entity. Unlike private-sector plans governed broadly by ERISA, most public plans operate under their own statutes and regulations. These programs often feature statutory exemptions from ERISA’s Title I protections, giving them flexibility in design and funding. In contrast, private-sector plans must meet ERISA’s nondiscrimination and funding standards, making their structures more uniform across industries.
The Three Main Types of Government Retirement Plans
Before we go deep into any one plan, it helps to know the basic categories. Government retirement plans usually fall into one of three groups.
- Defined Benefit (DB) plans pay a set monthly amount after you retire, based on a formula
- Defined Contribution (DC) plans put money into your own account, and the balance depends on how much is put in and how it grows
- Hybrid plans mix features from both
| Plan Type | Who Carries the Risk | Example |
|---|---|---|
| Defined Benefit | Employer | FERS Basic Benefit, state pensions |
| Defined Contribution | Employee | TSP, 403(b), 457(b) |
| Hybrid | Shared | Cash balance plans |
Defined Benefit Plans and How FERS Works
Defined benefit plans are the classic pension. You work for a set number of years, and when you retire, you get paid a fixed amount every month, usually for the rest of your life. The formula most plans use looks like this:
Annual Benefit = Accrual Rate x Years of Service x High-3 Average Salary
Your high-3 is just the average of your highest three years of pay.
The Federal Employees Retirement System, or FERS, covers most federal workers hired after 1987. It actually has three parts working together, not just one. There is the Basic Benefit Plan, which is the pension part. There is Social Security, same as any other worker gets. And there is the Thrift Savings Plan, which works more like a 401(k). Employees pay 0.8% of salary toward the Basic Benefit and 6.2% toward Social Security, and the agency chips in matching contributions on top.
Here is what the numbers can look like for someone with 30 years of service and a high-3 salary of $80,000:
| Accrual Rate | Annual Pension | Monthly Pension |
|---|---|---|
| 1% (standard) | $24,000 | $2,000 |
| 1.1% (age 62+ with 20+ years) | $26,400 | $2,200 |
Some jobs get a better deal. Customs and Border Protection officers in law enforcement roles, for example, can retire as early as 57 with 20 years of service, and their accrual rate is 1.7% for those first 20 years.
State and city pensions work in a similar spirit but the details change from place to place. And many of them are dealing with funding gaps right now. A 2023 survey by NASRA looked at 126 large public pension plans and found the average funded level was only 76.4%. That means liabilities have grown faster than the money set aside to pay them, mostly because people are living longer and returns have not always kept up.
Defined Contribution Plans: TSP, 403(b), and 457(b)
Defined contribution plans flip the risk onto you. Instead of a guaranteed check, you and your employer put money into an account, you pick the investments, and your balance grows or shrinks depending on the market. For federal workers, this account is called the Thrift Savings Plan, or TSP.
TSP gives you five basic funds to choose from, plus 11 lifecycle funds that automatically shift your mix as you get closer to retirement.
- G Fund – government securities, the safest option
- F Fund – fixed income bonds
- C Fund – large U.S. company stocks
- S Fund – small and mid-size U.S. stocks
- I Fund – international stocks
Fees are low too. The L 2065 fund, for example, charges just 0.04%. New employees are automatically enrolled at a 5% deferral rate unless they choose otherwise, and the agency matches part of that, usually adding up to 6% total when you save 5% yourself.
If you’re not federal, you’re more likely dealing with a 403(b) or 457(b) plan instead. Teachers and nonprofit staff usually get a 403(b). State and local government workers usually get a 457(b). Here’s how the two stack up:
| Feature | 403(b) | 457(b) |
|---|---|---|
| Who uses it | Public schools, nonprofits | State and local government |
| 2025 contribution limit | $23,500 | $23,500 |
| Catch-up at age 50+ | $7,500 | $7,500 |
| Early withdrawal penalty | 10% before age 59½ | None once you leave the job |
Nonprofits that sponsor a 403(b) plan usually still have ERISA fiduciary duties to worry about, unlike most government plans. If that sounds like your organization, a 3(16) administrator can take over the daily filing and compliance work so nobody on staff has to become an ERISA expert overnight.
Saving consistently adds up more than people expect. Putting away $5,000 a year for 35 years at a 6% return grows to roughly $472,300. Max out the 2025 limit of $23,500 a year under the same assumptions, and you’re looking at close to $2.2 million by the time you retire. Small numbers over a long career turn into real money.
Hybrid and Cash Balance Plans
Hybrid plans try to give you the best of both worlds, a pension guarantee plus a clear account balance you can actually track. The most common version in government work is the cash balance plan. Each year your account gets two credits:
- A pay credit, usually a fixed percent of your salary
- An interest credit, either a set rate or one tied to something like the 30-year Treasury yield
At retirement you can take the balance as a lump sum, or convert it into a monthly annuity. A few real examples show how this plays out differently depending on the state. Indiana’s PERF offers a cash balance option for some workers. Michigan’s MPSERS built a hybrid tier for new teachers. San Diego’s city pension guarantees a minimum pension on top of extra cash balance savings.
These plans are easier to understand month to month, since you can see your balance grow like a savings account. But they can also be harder to explain during onboarding, and interest credit costs can rise if rates go up unexpectedly.
Vesting, Rollovers, and Getting Your Money Out
Vesting is the point where employer money truly becomes yours, even if you leave. It’s worth knowing your numbers here before you make any career moves.
| Plan | Vesting Period |
|---|---|
| TSP match (FERS) | 2 years |
| FERS pension | 5 years |
| CSRS pension | 3 years |
| State and local pensions | 5 to 10 years, depends on the state |
One more thing about vesting. If you leave your job and come back after a break of more than a year, some plans reset your vesting clock back to zero. Shorter breaks are usually fine, and some plans let you “buy back” your old service by repaying past contributions.
When you leave a job, you usually have a few choices for your account. You can roll it directly into an IRA with no tax hit. You can move it into a new employer’s plan if they accept rollovers. Or with TSP, you can simply leave it where it is. If you take a check yourself instead of a direct rollover, you have 60 days to deposit the full amount somewhere else, or you’ll owe taxes plus a possible 10% penalty on top.
Most withdrawals before age 59½ carry that same 10% penalty along with regular income tax. There are a few exceptions worth remembering. 457(b) plans allow penalty-free withdrawals once you separate from the job. Hardship withdrawals are sometimes allowed for medical bills or to prevent eviction. And if you become disabled, the penalty is usually waived.
Loans work a bit differently. TSP lets you borrow up to 50% of your balance, capped at $50,000, with five years to repay a general purpose loan or up to 15 years for a home purchase loan. Many state DC plans offer something similar.
TSP loan interest is set at the G Fund rate at the time you take the loan, and that interest goes back into your own account, not to anyone else. State DC plans work a bit differently. Their interest rate is often tied to something like the prime rate plus a small margin. If you leave your job with a loan still unpaid, you’ll usually need to pay it off in full, or it gets treated as a taxable withdrawal.
Survivor Benefits, Disability, and Cost of Living
Retirement plans usually protect more than just the retiree. FERS retirees can choose to give their spouse 50% of their pension after they pass away, though their own monthly check gets reduced by around 6.8% to pay for it. CSRS retirees can choose 55% survivor coverage instead, funded by a 2.5% contribution during their working years.
Disability is covered too, though the rules differ by system. FERS requires at least 18 months of service, and you must apply within a year of leaving your job. CSRS asks for three years of service. Disability pay works on a formula too. Under FERS, if you have less than 20 years of service, you get the lower of two numbers, either 60% of your high-3 average salary, or your normal pension formula amount. If you have 20 or more years of service, or you meet the MRA+10 rule, you get an unreduced pension instead.
On the cost of living side, CSRS retirees get a full yearly adjustment tied to inflation, while FERS retirees only start getting COLA increases after turning 62, and even then the bump can run a bit behind actual inflation.
FERS Special Retirement Supplement
FERS also offers something called the Special Retirement Supplement. This is extra money paid between the time you retire and age 62, when Social Security actually starts. It’s meant to bridge that gap so your income doesn’t drop before Social Security kicks in. To qualify, you need to retire under the MRA+10 rule with at least 30 years of service, or 20 years of service if you’re retiring at age 60.
Final Thoughts
Government retirement plans aren’t one-size-fits-all, and that’s actually a good thing once you understand the differences. A guaranteed pension gives you certainty. A savings account gives you control and portability. A hybrid plan tries to split the difference. Knowing which one covers you, and what your vesting and contribution rules look like, puts you in a much better spot when retirement actually shows up.
If you sponsor a 403(b), 401(k), or similar plan for your organization and want help handling the fiduciary side of things, it may be worth talking to a retirement fiduciary about where your responsibilities begin and end. Reach out to a team that handles this daily, and let them walk you through what fits your plan.
