In 2019, the Washington State Legislature passed a law requiring employers to report SOC codes in their quarterly reports for unemployment insurance. Both taxable and reimbursable employers need to report SOC codes. Reporting SOC codes does not affect your tax rates.

What are SOC codes?


SOC stands for Standard Occupational Classification. It’s a federal coding system that helps government agencies and private businesses compare occupational data.

This data is used by:

  • Government program managers.
  • Industry and labor relations specialists.
  • Students considering career training.
  • Job seekers.
  • Vocational training schools.
  • Employers wishing to set salaries or locate a new business.

SOC codes are not the same as codes you submit to the state Department of Labor & Industries (L&I). Go to the L&I website for information about their risk classification codes.
