California Insurance Commissioner Ricardo Lara adopted a new advisory pure premium rate for workers' compensation insurance on July 10, 2026, setting it at $1.65 per $100 of payroll — a 6.6% increase over the 2025 approved rate. According to the California Department of Insurance, the new advisory pure premium rate is effective September 1, 2026.

For California small-business owners, the practical question is straightforward: what will this do to renewal quotes, and how should you plan payroll and cash flow around it? Insurers are not required to use the advisory rate, so your renewal could come in higher or lower than the 6.6% benchmark. The Department attributed the increase to higher claim-related costs, so owners should plan for possible renewal pressure rather than assume the benchmark will be temporary.

What did Commissioner Lara actually do?

The adopted rate of $1.65 per $100 of payroll is an advisory pure premium rate. That is a benchmark, not a mandate. Insurance companies operating in California file their own rates and are free to price above or below the Commissioner's number based on their loss experience, expenses, and business mix.

The Workers' Compensation Insurance Rating Bureau of California (WCIRB), the licensed statistical agent for the state, had requested a 10.4% increase. Department of Insurance actuaries recommended a smaller adjustment, and Commissioner Lara adopted the lower figure. An actuary representing the public members of the WCIRB board also recommended a rate increase, so the debate was over the size of the change, not whether costs are rising.

In the Department's announcement, Commissioner Lara said: "Our actions must be guided by data and focused on maintaining a workers' compensation system that protects injured workers, supports California businesses, and promotes a stable and competitive insurance marketplace."

Why are workers' comp rates going up in California?

The Department pointed to four cost pressures pushing loss ratios higher:

• Higher medical treatment costs on open and new claims.
• Higher medical-legal costs, meaning the expense of medical evaluations used to resolve disputed claims.
• More projected cumulative trauma claims, meaning injuries attributed to repeated exposure rather than a single incident.
• Higher claim-adjustment expenses, meaning it costs more for insurers to investigate and administer each claim.

At the same time, the rates insurers have been charging remained low, which is why accident-year combined ratios, a standard measure of underwriting profitability, have been deteriorating. Wage growth from a stronger economy has offset some of the pressure because premium scales with payroll, but not enough to close the gap.

What does the rate change mean for a California small business?

The California Department of Industrial Relations says California employers, including employers with one employee, generally must have workers' compensation insurance or be self-insured. That baseline obligation does not change with this rate action. What can change is the number on your renewal quote.

Three things to keep in mind:

1. The advisory rate is a benchmark, not your rate. Your actual premium depends on your class code (which reflects the type of work your employees do), your experience modifier (which reflects your own claims history), your payroll, and the individual insurer's filed rates. A landscaper, an accounting firm, and an HVAC contractor start from very different pure premium rates before any of that math happens.

2. Your experience modifier still matters. A lower experience modifier may help reduce the impact of statewide rate pressure, but the effect depends on your payroll, class codes, claims history, and insurer pricing. If you had a claim recently, you may see a compounding effect.

3. The effective date is September 1, 2026. Ask your broker how insurer filings may affect policies written or renewed around that date. Insurers can and do file rate changes at other points in the year.

How should you prepare for your next workers' comp renewal?

Before renewal, you can check the inputs that affect your quote and reduce avoidable surprises.

Audit your class codes. Employees are assigned class codes based on the work they actually do. If an office manager is coded as field labor instead of clerical staff, the business may be quoted a higher rate than the role requires. Ask your broker for a class-code review, and be ready to describe what each employee actually does day to day.

Reconcile payroll early. Workers' comp premium is based on estimated payroll at bind and then trued up at audit. If you overestimate payroll, you pay too much up front and wait for a refund. If you underestimate, you get an audit bill after the policy expires. Neither is good for cash flow. Pull year-to-date payroll from your accounting or payroll system and use that as the basis for the next policy's estimate.

Document safety programs and return-to-work practices. Written safety programs, documented training, and a return-to-work policy that gets injured employees back on modified duty can affect loss experience over time. Ask your broker whether your insurer considers documented safety programs or return-to-work practices when pricing your policy.

Get more than one quote. Because insurers can price above or below the advisory rate, quotes for the same business in the same class code can vary meaningfully. Two or three quotes from an independent broker is standard practice.

How should California small businesses budget for the workers' comp rate change?

For planning purposes, a 6.6% benchmark increase on a policy that ran $8,000 last year works out to roughly $528 more, assuming your insurer moves in line with the benchmark and nothing else on your policy changes. On a $25,000 policy, it's about $1,650. Those are illustrative, not predictions. Your renewal could be flat, higher, or lower depending on the factors above.

Where should businesses hold money for insurance premiums?

Workers' comp premium is one of the more predictable large line items in a small business's year: you know roughly when the renewal hits, you know the payroll base, and you can plan for it. The problem is that it often lands the same month as quarterly taxes or a big vendor payment.

Setting aside the estimated renewal amount monthly keeps the payment from competing with payroll or rent when the invoice arrives. Novo business checking has a $0 monthly fee, and Novo Reserves can help you earmark funds for recurring obligations like insurance premiums, quarterly estimated taxes, and payroll. One tradeoff to know up front: Novo does not accept cash deposits, so cash-heavy operations will need a solution for that piece.

Frequently asked questions

Does the new rate apply to my policy immediately?

The advisory pure premium rate is effective September 1, 2026, but your actual renewal timing depends on your policy date and your insurer's filed rates. Ask your broker how the effective date applies to your policy.

Am I required to use an insurer that follows the advisory rate?

No. California workers' compensation is an open, competitive market. Insurers file their own rates. The Commissioner's advisory rate is a benchmark that reflects the Department's actuarial view of what pure loss costs will be, and insurers can price above or below it.

If I'm a sole proprietor with no employees, do I need coverage?

If you are a sole proprietor with no employees, confirm your workers' compensation obligation with a licensed broker or the California Department of Industrial Relations before deciding whether to carry coverage. Some contracts, particularly with general contractors or larger clients, require coverage as a condition of doing business.

What is the difference between the pure premium rate and my final premium?

The pure premium rate covers expected losses and loss-adjustment expenses. Your final premium adds insurer expenses, profit, taxes, and assessments, and is then modified by your class code mix, payroll, and experience modifier.

Where can I check my insurer's filed rates?

The California Department of Insurance operates a public rate-filing system accessible through insurance.ca.gov. Filings are viewable through the Department's Virtual Viewing Room.

What should California employers do before renewal?

Rates are moving up because claim costs are moving up, and the Commissioner's 6.6% figure is a smaller increase than the rating bureau requested but still an increase. Plan for it, shop your renewal, and check your class codes and experience modifier before you accept the first quote. The advisory rate is one input insurers may consider, not the final price on your renewal.
