Published June 25, 2026·6 min read

Calculating Washington L&I rates for 2026 is essential for small businesses and solo-entrepreneurs in the state. Understanding these rates can help you manage your payroll taxes effectively and ensure compliance with state regulations. Washington's Labor & Industries (L&I) insurance provides coverage for work-related injuries and illnesses, and the rates vary by industry. In this guide, I'll walk you through how to calculate these rates and what factors you need to consider to ensure you're accurately assessing your payroll taxes in 2026.

Understanding Washington L&I Rates in 2026

The Washington L&I rates for 2026 depend on various factors, including the type of business you operate and your industry classification. Each industry has its own risk classification which determines its L&I insurance rate. You can find these classifications and corresponding rates on the Washington State L&I website. Generally, higher-risk industries will have higher rates compared to lower-risk ones. It's crucial to use the correct classification to avoid overpaying or underpaying your L&I insurance.

Steps to Calculate L&I Insurance Rates

1. Identify your industry classification — Use the Washington State L&I classification codes to determine your specific industry. This is crucial as rates vary significantly by industry. 2. Find the applicable rate — Once you know your classification, look up the corresponding L&I rate for 2026. This information is available on the L&I website. 3. Calculate your payroll — Determine your total payroll for the year. This includes wages paid to all employees. 4. Apply the rate — Multiply your total payroll by your industry's L&I rate. This gives you the total L&I insurance cost for the year. 5. Adjust for experience rating — If your business has a history of fewer claims, you might qualify for a lower rate. This adjustment can further reduce your costs.

Other Payroll Taxes to Consider in 2026

In addition to calculating Washington L&I rates, you need to account for other payroll taxes. For 2026, federal Social Security tax is set at 6.2% on wages up to $176,100. Medicare tax is 1.45% on all wages, with an additional 0.9% for high earners. Washington Paid Family and Medical Leave (PFML) tax is 0.74%, while the WA Cares Fund tax is 0.58%. Together, these taxes contribute to your overall payroll obligations. Make sure to factor these numbers into your calculations to avoid any surprises during tax season.
