If you work for one of the twenty California counties that runs its own pension plan under the County Employees Retirement Law of 1937, your retirement benefit comes from a defined benefit formula based on your age at retirement, your years of credited service, and your highest average pay. The 1937 Act county retirement systems operate independently of CalPERS, and the specifics of your pension depend on which county employs you, whether you’re classified as a General or Safety member, and whether you were hired before or after January 1, 2013.
Which Counties and Employers Are Covered
Twenty counties are authorized to maintain independent retirement associations under the CERL rather than contracting with CalPERS.1State Association of County Retirement Systems. County Employees Retirement Law (CERL) The largest include Los Angeles, Orange, Sacramento, San Diego, San Bernardino, Alameda, Contra Costa, and Fresno. The others are Imperial, Kern, Marin, Mendocino, Merced, San Joaquin, San Mateo, Santa Barbara, Sonoma, Stanislaus, Tulare, and Ventura. Each system has its own board of retirement, its own investments, and its own administrative office.
Coverage isn’t limited to direct county employees. Air quality districts, sanitation agencies, park districts, transportation authorities, and other special districts inside these counties often participate as member employers. If your paycheck comes from one of those districts, you’re likely a CERL member even if you don’t think of yourself as a county worker.
Becoming a Member and Getting Vested
You become a member automatically when you start a permanent position that meets the minimum hourly threshold your county’s retirement board has set. Members fall into two main categories. General members hold the broad range of county positions. Safety members hold jobs involving the direct protection of life and property, most commonly law enforcement officers, firefighters, and certain probation officers. Safety members have different retirement ages, different formulas, and in some counties a mandatory retirement age.
Vesting takes five years of credited service. Once vested, you have a guaranteed right to a future pension even if you leave county work before retirement age. If you leave with at least five years and don’t affirmatively choose an option, Government Code Section 31700 deems you to have elected deferred retirement, so the default preserves your benefit rather than refunding you out of the system.2Santa Barbara County Employees’ Retirement System. County Employees Retirement Law of 1937 (CERL) – Section 31700
Legacy Members and PEPRA Members
Your hire date sorts you into one of two rulebooks. Employees who first entered a CERL system before January 1, 2013, are Legacy (or Classic) members.3Los Angeles County Employees Retirement Association. Plans ABC – Pension Reform Those hired on or after that date generally fall under the California Public Employees’ Pension Reform Act of 2013 (PEPRA). One exception matters: if you worked for another California public employer before 2013 and established reciprocity within six months of joining a CERL system, you keep Legacy status even with a post-2012 CERL start date.4California Legislative Information. California Code Government Code GOV 7522.02 Legacy and PEPRA members use different formulas, different compensation definitions, and different caps on pensionable pay.
How Your Pension Is Calculated
The formula has three inputs: your age at retirement, your years of credited service, and your final average compensation. Each year of service earns a percentage of pay, and that percentage increases with the age at which you retire. Retire at 55 and each year of service is worth less than if you retire at 62. Written out: Age Factor × Years of Service × Final Average Compensation = Annual Pension.
Final Average Compensation
For most Legacy members, the system averages your highest 36 consecutive months of “compensation earnable” to find final average compensation. Some Legacy tiers use a 12-month window instead, depending on the member’s entry date and the county.5Ventura County Employees’ Retirement Association. Final Average Compensation Under Government Code Section 31461, compensation earnable is built from the average pay for your position based on the ordinary work schedule for your job classification, and it can include certain pay differentials and recurring bonuses on top of base salary.6San Mateo County Employees’ Retirement Association. Resolution Defining Compensation Earnable Pursuant to Government Code 31461
PEPRA members use a narrower measure called “pensionable compensation,” which is generally limited to base pay and standard recurring items. Overtime, one-time bonuses, and cash-outs of unused leave don’t count. PEPRA members always use a 36-month averaging period, and their pensionable compensation is capped each year by the state. For 2026, the cap is $159,733 if your employer participates in Social Security and $191,679 if it does not.7CalPERS. 2026 Compensation Limits for Classic and PEPRA Members These caps adjust annually with inflation.
The Federal Benefit Ceiling
Federal tax law also caps how much any defined benefit plan can pay out. Under Internal Revenue Code Section 415(b), the maximum annual pension from a single defined benefit plan is $290,000 for 2026.8Internal Revenue Service. Retirement Topics – Defined Benefit Plan Benefit Limits That limit applies to the pension itself, not to the salary used in the calculation. Most members won’t approach it, but long-serving members in high-ranking positions occasionally do.
The Different Kinds of Retirement
Service Retirement
A service retirement is the standard case: you meet your tier’s minimum age and service requirements and start drawing a monthly pension for life. For most General members, that means reaching at least age 50 with ten years of service, though the exact combinations vary by tier. Safety members can often retire earlier. PEPRA members face somewhat higher minimum retirement ages than Legacy members in the same county.
Disability Retirement
If a medical condition permanently prevents you from doing your job, you may qualify for disability retirement regardless of your age. Government Code Section 31720 provides a service-connected disability retirement when a workplace injury or illness substantially caused the incapacity, and it is available regardless of how many years of service you have because the injury arose from the employment itself.9Justia. California Code Government Code 31720 The benefit is often more favorable and carries tax advantages compared with a standard service pension.
A non-service-connected disability retirement covers incapacity unrelated to your job and requires at least five years of credited service. Either track involves medical evaluations and a determination by the retirement board that the condition is permanent and prevents you from performing your duties.
Deferred Retirement
Leaving county work after vesting but before retirement age doesn’t cost you your pension. You can leave your contributions in the fund and claim a deferred retirement when you reach the age you would have been eligible had you stayed. Your benefit is calculated under the law as it stands when you actually start collecting, not when you left.10Santa Barbara County Employees’ Retirement System. County Employees Retirement Law of 1937 (CERL) – Section 31705 The alternative is withdrawing your contributions, but doing so permanently forfeits the employer-funded portion of your benefit.
Mandatory Retirement for Some Safety Members
Some counties impose a mandatory retirement age on Safety members. Under Government Code Section 31662.4, a county’s board of supervisors can require Safety members (other than elected officials) to retire at age 60, with an exception allowing sheriffs and undersheriffs to serve until age 70.11Justia. California Code Government Code 31662-31664.65 Not every CERL county has activated this provision, so whether it applies depends on where you work.
Cost-of-Living Adjustments
CERL pensions include annual cost-of-living adjustments tied to the Consumer Price Index, but each county caps the yearly increase, usually at 2%, 3%, or 5% depending on the tier. When inflation runs above the cap, the excess percentage rolls into a “COLA bank” the system draws from in years when inflation runs below the maximum.12Los Angeles County Employees Retirement Association. COLA Accumulation The banking mechanism smooths adjustments across years, so your benefit tracks inflation more consistently than a hard yearly cap alone would allow.
Survivor and Beneficiary Protections
If an active member dies before retirement, the system pays a lump-sum death benefit equal to the member’s accumulated contributions plus credited interest. For retirees, the protections are more substantial.
Under Government Code Section 31760.1, when a retired member dies, 60 percent of the member’s pension (if not already modified by an optional settlement) continues for life to the surviving spouse or registered domestic partner.13California Legislative Information. California Code Government Code GOV 31760.1 The continuing allowance applies automatically in counties that have adopted the relevant provisions. Under Government Code Section 31760.2, the marriage or domestic partnership must have existed for at least two years before the member’s death and the surviving spouse must have reached age 55 by that date.14California Legislative Information. California Code Government Code GOV 31760.2 The exact requirements depend on which section your county has adopted, so verify the details with your retirement system.
Optional Settlements at Retirement
At retirement, you can choose one of four optional settlements that reduce your monthly pension in exchange for a larger or guaranteed benefit to your designated beneficiary after your death.15Santa Barbara County Employees’ Retirement System. County Employees Retirement Law of 1937 (CERL) – Sections 31760-31764
- Option 1 pays a reduced pension for life; if you die before collecting an amount equal to your accumulated contributions at retirement, the remaining balance goes to your estate or a named beneficiary.
- Option 2 pays a reduced pension for life, and 100 percent of that reduced amount continues to your named beneficiary for their lifetime after your death.
- Option 3 pays a slightly less reduced pension for life, and 50 percent of that amount continues to your named beneficiary for their lifetime.
- Option 4 is a flexible arrangement approved by the board and actuary, allowing a customized benefit to one or more named beneficiaries.
Once your first retirement check is issued, the election is irrevocable. The size of the reduction to your own benefit depends on both your age and your beneficiary’s age at retirement, since the actuary must equalize the expected total payout across options. Model the scenarios with your retirement system’s staff before you sign anything.
Reciprocity With CalPERS and Other Systems
If you move between a CERL system and CalPERS or another California public retirement system that has a reciprocal agreement, you can link your service across both. Reciprocity doesn’t transfer contributions or service credit. Both systems coordinate so your combined service counts toward eligibility, and the highest final compensation from either system can be used to calculate the benefit from both.16CalPERS. Reciprocity (Linking Retirement Systems)
To establish reciprocity, you generally must join the new system within a specific window after leaving the old one. At retirement, you apply to both systems using the same retirement date and receive separate monthly payments from each. Reciprocity also determines whether you’re treated as a Legacy or PEPRA member: if you had active membership in the earlier system before 2013, you keep Legacy status in the new one.4California Legislative Information. California Code Government Code GOV 7522.02
Buying Service Credit for Gaps
If your service history has gaps, you may be able to buy credit for certain periods and increase your pension. Common eligible categories include work for a covered employer before you were enrolled, unpaid medical leave of up to twelve consecutive months per absence, active-duty military leave, and prior service with another California public agency or the federal government if you are not already receiving or eligible for a pension from that service.17Stanislaus County Employees’ Retirement Association. Service Purchase Q and A
You can also redeposit contributions you previously withdrew. If you left, took a refund, and later returned to covered employment, paying back the withdrawn amount plus interest restores the original service credit. Payment can be by lump sum, pretax rollover from a 401(k), traditional IRA, or 457 plan, or payroll deduction. Installment plans accrue additional interest, and the CERL limits their length based on the type of credit purchased.
Taxes on Your Pension
CERL pension payments are subject to federal income tax. If you never made after-tax contributions to the system, the entire monthly pension is taxable. If you made after-tax contributions, part of each payment representing the return of those contributions is tax-free and the rest is taxable.18Internal Revenue Service. Topic No. 410 Pensions and Annuities Your system withholds federal tax based on the Form W-4P you file, so keep the withholding matched to your actual tax situation.
Members who retire before age 59½ may face a 10 percent additional tax on early distributions. Safety members and other public safety employees of a state or local government are exempt from this penalty if they separate from service during or after the year they turn 50.19Internal Revenue Service. Retirement Topics – Exceptions to Tax on Early Distributions
California treats pension income as ordinary income. There is no special state exclusion for public employee pensions. If you move out of California after retiring, federal law (4 U.S.C. § 114) prohibits the state from taxing your CERL pension as a former resident.
Social Security and the End of WEP and GPO
Several CERL counties don’t participate in Social Security, so no Social Security taxes come out of your paycheck and you earn no Social Security credits for that work. For decades, members who earned Social Security through other jobs saw two reductions: the Windfall Elimination Provision cut their own Social Security retirement benefit, and the Government Pension Offset cut spousal or survivor benefits. The Social Security Fairness Act, signed on January 5, 2025, eliminated both.20Social Security Administration. Program Explainer Windfall Elimination Provision21Social Security Administration. Program Explainer Government Pension Offset CERL members who also qualify for Social Security now receive the full amount of both benefits without reduction.
Going Back to Work After You Retire
Returning to work for a CERL employer after retirement is possible, but the rules are strict. You must wait at least 180 days after your retirement date before starting employment with a participating employer, and there cannot be any pre-retirement agreement, written or verbal, to return.22CalPERS. Retired Annuitant The restrictions exist to prevent retire-and-rehire arrangements that undermine the pension system.
Once you do return, your work is capped at 960 hours per fiscal year. Exceeding that cap can suspend your retirement allowance. The position must pay the same rate as the employer pays other employees doing similar work; no special arrangement for you. Employment with a private employer, or with a public employer outside your retirement system, doesn’t trigger any of these restrictions.
