The Business License Application (BLA) is a simplified application used to apply for many state and city endorsements, registrations, and permits. You may use it to:
- Apply for a Washington State Unified Business Identifier (UBI) number or tax registration number.
- Open or reopen a business.
- Change ownership of a business.
- Open a new or change a business location.
- Register or change a trade name.
- Hire employees.
- Apply for a Minor Work Permit.
- Add an endorsement to an existing business location.
- Get optional insurance coverage for the business owner.
Hire people to work in or around your home.
A UBI number is a nine-digit number that registers you with several state agencies and allows you to do business in Washington State. A UBI number is sometimes called a tax registration number, a business registration number, or a business license number. Use the Business License Application to apply for a UBI number.
As soon as the UBI is issued, you may begin using it for business purposes. Some business licenses require that you have the license posted before you can officially open your business to the public.
You need a license if you meet one or more of the following criteria:
- Your business requires city and state endorsements.
- You are doing business using a name other than your full name legal name.
- You plan to hire employees within the next 90 days.
- You sell a product or provide a service that requires the collection of sales tax.
- Your gross income is $12,000 per year or more.
- Your business is required to pay taxes or fees to the Department of Revenue.
- You are a buyer or processor of specialty wood products.

Are there other licensing requirements I must meet that aren’t covered by the Business License Application?

To look up business information online, go to:
- Business Lookup - When you are using the Business Lookup tool, you will first need to select the type of account you are looking for. The most common search types are by tax account, reseller permit, and by general business license.
Tax account: use this search to show information related to the registered tax account. This name may not be the same as the trade name the business is operating under, and not all businesses will have a tax account.
Reseller permit: use this search to verify the business name on a reseller permit, if it is active, and the effective dates.
General business license: use this search to find information about the Department of Revenue business license. This may not be the same name that is used for a tax account.
Secretary of State Corporations Registration Data Search - Corporation and limited liability company names.
- U.S. Patent and Trademark Commission - Search for federally registered names.
If your business is a corporation, a limited liability company, a limited liability partnership, or requires a state or city endorsement available through the Business Licensing Service, you will need to renew your license annually. The expiration date is determined when you apply, and will be printed on the top right hand side of your Business License under the Unified Business Identifier (UBI) number.
Business Licensing Service sends a courtesy renewal notice to owners approximately 45 days before their license expires. If you don’t receive a renewal notice, please contact the Business Licensing Service at 360-705-6741.
For licenses not handled through the Business Licensing Service, contact the regulatory agency listed on your license or permit.
Business licenses with state or city endorsements are renewed annually. If any of these endorsements appear on your Business License, an expiration date will be printed in the upper right-hand corner.
If you have multiple endorsements, it is possible that there are multiple expiration dates, and those dates will be printed next to the endorsement they refer to.
Renewals are due before the expiration date printed on your Business License.

To file by mail:
Call 360-705-6705 to have a paper copy of your renewal form, with the itemized fees for your accounts, mailed to the mailing address on file.
Courtesy reminders for renewals are mailed out 45 days before the expiration date. Regardless of whether this notice is received your renewal is due by the expiration date printed on the license. Penalty fees will be charged if not completed by the expiration date.
You are eligible to renew your Business License up to two months before the expiration date printed on your license.
Renewals are due by the expiration date. Renewals received after the expiration date are charged a late penalty fee. These fees cannot be waived, for further details see RCW 19.02.085.
Renewals will prorate to an existing expiration date in the following situations:
- A new city has partnered with the DOR to do their city licensing and had a different expiration date on file from the DOR.
A state endorsement was recently applied for. Most state endorsement origination fees pay for a full 12 months, and the expiration date prorates to the existing expiration date on file.
You should receive your tax forms from the Department of Revenue, Department of Labor and Industries, and the Employment Security Department at the end of the first quarter in which you start reporting. You will need to file personal property taxes with your county assessor. Contact your local assessor for instructions.
New accounts generally need to report every quarter; however, you may change your reporting frequency to monthly or annually. You will be notified of any changes and sent the appropriate tax returns for filing. Personal property listings must be filed with your county assessor's office by April 30 of each year.
