Washington's Labor & Industries (L&I) taxes are essential for funding workers' compensation and other employee benefits. With the right information and tools, you can confidently handle these calculations and keep your business running smoothly. Let's break down the process, focusing on the current rates and requirements.

Understanding WA L&I Taxes

Washington L&I taxes are mandatory for employers and vary depending on your industry. These taxes fund the state's workers' compensation system, which provides benefits to employees who are injured on the job. The rates for L&I taxes can change yearly, so it's important to stay updated with the latest rates for 2026.

In 2026, the L&I tax rates will vary significantly based on your business's classification. For most businesses, the rates will range from 0.1% to 12.5% of your employee's gross wages. To determine the specific rate for your industry, you can consult the L&I website or your industry association.

Steps to Calculate Washington L&I Taxes

1. Gather employee wage data — Start by collecting the gross wages for each employee. This includes hourly wages, salaries, and any bonuses. 2. Identify your industry classification — Look up your business's industry classification in the L&I database to find the applicable tax rate. 3. Calculate L&I tax for each employee — Multiply each employee's gross wages by your industry's L&I tax rate. For example, if your employee earns $50,000 annually and your rate is 2.5%, the L&I tax would be $1,250. 4. Sum the total L&I taxes — Add up the calculated L&I taxes for all employees to get the total L&I tax liability for your business.
