The Internal Revenue
Service (IRS) is
a federal, not
a Washington State, agency.
Whether or not you plan to
hire workers, you must get
an Employer Identification
Number (EIN) for your business.
Get one at IRS.gov/ss4.
Sole proprietorships that
won’t have employees are an
exception. They can choose
to use their Social Security
number as their federal business
identification number, though
they may not want to for
security reasons.
Upon request, foreign language support and formats for
persons with disabilities are available. Call 1-800-547-8367.
TDD users, call 711. L&I is an equal opportunity employer. PUBLICATION F101-079-000 [11-2023]
