Washington registration and tax info

• Washington Department of Revenue - business license
  • You'll register with this agency first—the other agency accounts will be created once your business license information is shared by this agency.
• Washington State Department of Labor and Industries (L&I) - worker’s compensation
• Washington Employment Security Department (ESD) - unemployment tax and Paid Family and Medical Leave

There are two options for registration, each with its own timeline for getting you the necessary tax account information you'll need before you can run payroll.

• Online registration—you'll receive tax account information 10 days after you complete the registration [recommended].
• By mail—you'll receive tax account information 6 weeks after sending in your business license application. 

Register your company in the state

1. The steps required to register as a business differ depending on your business structure:
   • Sole proprietorships and general partnerships
     • File a Business License Application with the Business Licensing Service.
   • Corporations, limited partnerships, LLCs and LLPs
     • First, create a business structure with the Office of the Secretary of State. 
     • Once the business structure is complete, file a Business License Application with the Business Licensing Service.
   • Businesses that are already licensed but that are hiring employees for the first time
     • Refile a business license application with the Business Licensing Service.
2. The Department of Revenue will process your application and:
   • Notify WA Labor & Industry (L&I) to open a workers' compensation account.
   • Notify the Employment Security Department (ESD) to open an unemployment insurance account.
3. You'll receive a letter from your new Workers' Comp account manager, and a packet of information which you'll need to retain that includes:
   • Your Unified Business Identification (UBI)
   • Your ES (Employment Security) Reference Number
   • Your Workers' Comp Account ID
   • Your Participant Activation Code (PAC) for WA L&I 
     • Reminder: the Department of Revenue no longer issues PAC codes–The PAC code Gusto requires will be issued by Washington L&I.
   • Your State Unemployment and Employment Administration Fund rate

The letter and packet will be sent to you 10 days after registering online, or within 6 weeks if registering by mail.

Workers' Compensation insurance protects and covers your business against injuries and illness that could occur as a direct result of the work done while your employees are on the job.

Washington requires that employers get their coverage through a state-operated fund—as such, Gusto will pay this insurance premium on your behalf to the state.

Once you've filed your business license (see instructions in the dropdown above), you can find the workers' comp rates assigned to you online.

• Heads up: Risk class codes are different than Standard Operational Classification (SOC) codes. SOC codes are also required for Washington employees—check out this article for more information.
