If you run a business in California with at least one employee, you must comply with the requirement for employer retirement plans in California. The state requires you to either enroll in CalSavers or offer a qualified private retirement plan.
Many business owners struggle with understanding deadlines, avoiding penalties, and choosing between CalSavers and private plans under the California employer retirement plan requirement.
This article covers who must comply, when deadlines hit, what penalties look like, and which plan options actually make sense for your business.
What the California Employer Retirement Plan Requirement Means
The California employer retirement plan requirement is a state law that forces California employers to give workers access to a retirement savings plan. If your business does not already offer a qualifying workplace retirement plan, you must register with CalSavers, California’s state-run retirement savings program.
The law exists because a large share of California’s private-sector workers had zero retirement savings access through their employers. The state created CalSavers to close that gap without putting the cost on employers. Understanding the California requirement for employer retirement plans fully, before a penalty notice arrives, is the smartest move any California business owner can make right now.
Which Employers Must Follow the Requirement
California employers with one or more W-2 employees not already enrolled in a qualified workplace retirement plan must comply with the requirement. The law originally applied to businesses with five or more employees.
Senate Bill 1126, signed in 2022, expanded it further. Now, even a business with just one employee must comply.
Employee Count, Eligibility, and Basic Rules
Employees must be at least 18 years old and work in California. Part-time workers qualify, not just full-time staff.
As an employer, you do not contribute anything. You only facilitate enrollment. Employees own their accounts and can opt out at any time with no penalty.
The rollout happened in phases based on employer size:
| Employer Size | Compliance Deadline |
| 100+ employees | September 30, 2020 |
| 50+ employees | June 30, 2021 |
| 5–99 employees | June 30, 2022 |
| 1–4 employees | December 31, 2025 |
Which Businesses May Be Exempt
Your business is exempt from the California employer retirement plan requirement if you already sponsor a qualifying retirement plan. These plans qualify:
- 401(k) plans
- 403(b) plans
- SEP IRAs
- SIMPLE IRAs
- Defined benefit pension plans
If you offer any of these, you register your exemption through the CalSavers employer portal at calsavers.com. You do not enroll in CalSavers itself. The exemption just confirms your existing plan satisfies the law.
When California Employers Need to Comply
For employers with five or more employees, every deadline has already passed. If you have not registered or claimed an exemption yet, enforcement is already possible. For businesses with one to four employees, the California employer retirement plan requirement deadline is December 31, 2025.
Registration and Employee Enrollment Basics
Registering with CalSavers takes about 30 minutes online. You need your federal EIN and basic employee details.
After you register:
- Upload your employee roster to the portal
- CalSavers sends enrollment notices directly to employees
- Employees get 30 days to set their preferences or opt out
- The default contribution is 5% of gross pay, with automatic 1% annual increases up to 8%
- The default account type is a Roth IRA
You do not select contribution amounts because employees control that. As an employer, you have to complete enrollment facilitation.
What Happens If an Employer Does Not Comply
The California Franchise Tax Board handles penalties.
- $250 per eligible employee if you are still non-compliant 90 days after receiving a formal notice
- $500 per eligible employee if you remain non-compliant 180 days after the notice
A 15-employee business that ignores both notices owes $11,250 in penalties. The state cross-references payroll records to identify non-compliant employers. There is no built-in grace period. The penalty clock starts when you receive the state’s notice, not when the original deadline passes.
Retirement Plan Options Employers Can Choose
The California employer retirement plan requirement gives you two paths: register with CalSavers, or offer a qualifying private plan. The difference is cost, tax benefit, and what you can do for your team.
A good retirement planning advisor can model both options against your payroll and tax situation before you lock in a decision.
CalSavers vs Private Retirement Plan Options
California employers choosing between CalSavers and a private plan should weigh these key differences:
| Feature | CalSavers | Private Plan (401k / SIMPLE IRA) |
| Setup cost | Free | Admin and setup fees apply |
| Employer contributions | Not allowed | Optional or required depending on plan type |
| Employee contribution limit | $7,000/year (Roth IRA limit) | Up to $23,000/year for 401(k)s |
| Employer tax deduction | None | Available if employer contributes |
| Admin work | Minimal | Moderate to high |
| Employee control | High | Varies by plan |
| Best fit | Very small businesses | Growing businesses wanting tax advantages |
CalSavers works cleanly if your goal is compliance with no added cost. A 401(k) plan gives employees six times the annual contribution room compared to CalSavers. A SIMPLE IRA is a middle-ground option. It costs less than a 401(k) to administer and offers employees up to $16,000 in annual contributions as of 2024. Employers must contribute to a SIMPLE IRA either through a 2% mandatory contribution or a 3% match, which is worth noting for budget planning.
How to Decide the Right Retirement Plan for Your Business
Picking the right retirement plan for your California business depends on your headcount, your budget, and what you want to offer long-term. A solid retirement-planning strategy starts with answering a few direct questions before you sign anything. The California employer retirement plan requirement does not tell you which private plan to pick. That part is your decision:
- Do you want a tax deduction? CalSavers gives you none. Employer contributions to a 401(k) plan or SIMPLE IRA are fully tax-deductible. This matters more as your payroll grows.
- How many employees do you have? CalSavers is genuinely the easiest path for businesses under 10 employees. Once you pass 20 employees, the 401(k)’s tax benefits and employee retention value start outweighing the extra admin cost.
- Can you handle annual filings? Private plans require Form 5500 filings and ongoing compliance monitoring. CalSavers does not.
- Are you trying to attract experienced workers? A 401(k) with any employer match beats CalSavers in a recruiting conversation every time. Employees notice the difference.
- What does your cash flow look like? If margins are tight, CalSavers costs nothing to run. That matters for businesses in early growth stages.
A retirement planning advisor who works with small California businesses can run real numbers based on your actual payroll. Choosing the right retirement plan is easier with someone who knows both California compliance rules and federal tax codes.
Tax planning for retirement decisions made at the employer level early on, especially around contribution structures, can save tens of thousands over a decade. A layered retirement planning strategy that accounts for both CalSavers fallback rules and private plan tax incentives gives you the clearest picture of your actual options.
Final Thoughts on Meeting the Employer Retirement Plan Requirement
The California employer retirement plan requirement is active, enforced, and only expanding. The real decision is how strategically you do it, whether through CalSavers for simplicity or a private plan for long-term tax efficiency and employee retention. Poor structuring today compounds into higher costs and limited flexibility later.
