What Does Workers’ Compensation Insurance Cover?
How Workers' Comp Premiums Are Calculated in Oregon and Washington
If you're comparing workers' compensation insurance in Oregon or Washington, the factors used to calculate your premium can differ by state. Your business type, employee duties, claims history and other risk factors all play a role.
In Oregon
Oregon workers' comp premiums are generally based on factors such as:
Class code: The rate assigned to your employees' type of work is based on its level of risk.
Payroll: Premiums are generally calculated using payroll and the applicable rate for each classification.
Claims history: Your business claims experience can affect the rate you pay.
For example, an office employee and a construction worker can have very different workers' compensation rates because their job risks are different.

In Washington
Washington handles workers' compensation differently. The state system uses risk classifications, base rates, and an experience factor to calculate premiums. Washington also bases workers' compensation premiums on hours worked, rather than simply charging a percentage of payroll.
Washington's experience factor can also change based on a business's claims experience compared with other businesses in the same risk classification. An experience factor below 1.0 generally reflects lower expected claim costs for that classification.
Because Oregon and Washington use different systems, business owners operating in both states should not assume that the same workers' comp pricing rules apply to both locations.
When Should You Get Workers’ Compensation Insurance?
Is Workers' Comp Required for Your Business in Oregon and Washington?
Oregon
Oregon law (ORS Chapter 656) requires most employers with one or more subject workers to carry workers' compensation coverage. Unlike some states, Oregon generally does not set a minimum employee count, so hiring even one part-time employee can trigger the requirement. A few exceptions exist, including:
Sole proprietors and business partners with no employees
Certain corporate officers who qualify for an exemption
Some categories of workers specifically excluded under Oregon law
Outside of these exceptions, employers with one or more subject workers generally must carry workers' compensation coverage. This is why workers comp insurance in Oregon is an important requirement for most businesses, including very small companies. For newer companies still building their risk profile, it's also important to understand that workers' compensation coverage is separate from general liability. Workers compensation insurance for small business owners is frequently paired with a general liability policy, so both employee injuries and third-party claims have separate coverage.

Washington
Washington has its own workers' compensation system and generally requires employers to provide coverage for their workers unless a specific exemption applies. Coverage is administered through the Washington State Department of Labor & Industries (L&I), and employers generally obtain coverage through L&I or qualify as a certified self-insured employer. Washington does not allow employers to purchase workers' compensation coverage from private insurance carriers.
Washington also handles workers' compensation differently when employees work across state lines. If an employee regularly works in Washington or lives in Washington and works remotely from there, the employer may need a Washington workers' compensation account and must report that employee to L&I. Businesses with employees working in both Oregon and Washington may need to follow the workers' compensation requirements of both states.
Because Oregon and Washington use different workers' compensation systems, business owners should review the requirements for each state rather than assuming that coverage rules are the same in both.

Ways to Manage Your Workers' Comp Costs Without Cutting Coverage
Getting the most affordable workers' compensation insurance isn't just about shopping carriers — it's about lowering the risk factors that drive your rate in the first place.
Classify jobs correctly. Make sure employees are reported under the appropriate risk classification. Incorrect classifications can affect the premium you pay.
Maintain a documented safety program. A strong workplace safety program can help reduce workplace injuries and claims.
Keep payroll and work-hour records accurate. Oregon and Washington use different methods when calculating workers' compensation premiums, so accurate records are especially important when you operate in both states.
Monitor your claims history. Claims of experience can affect future workers' compensation costs. Washington, for example, uses an experience factor when calculating individual business rates.
Bundle with your commercial auto or property coverage. Carriers sometimes price these together more competitively than standalone policies.
For small business owners, an annual review can help identify classification, reporting, or coverage issues before they result in unexpected costs.

Most workers comp insurance in Oregon policies include both parts by default, so you're rarely buying employer liability as a standalone product. The distinction matters most when an injury leads to a lawsuit rather than a straightforward claim — that's when the liability side of the policy gets used. If your business carries higher injury risk (construction, manufacturing, transportation), it's worth asking your agent whether your liability limits should sit higher than the state minimum, and whether a separate commercial property or general liability policy is also needed to close any remaining gaps.
