Without a Unified Business Identifier (UBI) number from the Washington State Department of Revenue, you cannot legally operate, open a business bank account, or apply for most local permits in Tacoma. This registration, also called a state business license or master business license, is issued by the Washington State Department of Revenue and serves as your core business tax ID. Key facts:

Your Washington State Business License and its associated Unified Business Identifier (UBI) Number are required for all businesses operating in Tacoma, as they establish your legal existence with the Washington State Department of Revenue. This registration is mandated under state law, including the Washington Business Corporation Act (RCW 23B), Limited Liability Company Act (RCW 25.15), and other statutes governing partnerships and trade names (RCW 19.80). It is the foundational step that authorizes you to conduct business, collect sales tax, and remit other state taxes. Without it, your restaurant is not legally recognized by the state, which blocks all subsequent local licensing steps with the City of Tacoma.
Operating without this active registration carries significant, escalating penalties. Based on Washington state administrative codes and court procedures, the consequences include:
Legal code: State business corporation act, LLC act, partnership act, assumed name statutes
Recent update: As of 2026, the state's Business Licensing Service (BLS) online portal has consolidated several endorsements, but the core UBI registration process and fees remain unchanged from the prior year.
| Type | Required | Notes |
|---|---|---|
| Restaurant (Full-Service) | Required | Any food service establishment with a permanent location that sells prepared food and employs staff is required to obtain a UBI, per the Washington State Department of Revenue (DOR) Business Licensing Service (BLS). |
| Bar / Nightclub | Required | These establishments are required for a UBI as they hold a liquor license, engage in retail sales, and are subject to business and occupation (B&O) tax reporting to the Washington DOR. |
| Food Truck | Required | A UBI is required for mobile vendors as they are considered a retail business conducting taxable sales in Washington, and the number is necessary to report sales tax and B&O tax. |
| Coffee Shop / Café | Required | Required because they sell retail goods (coffee, food) for consumption on or off-premises, triggering the need for a UBI for tax reporting to the state. |

See Full Requirements →Enter the exact, official name of your business as it is registered with the Washington Secretary of State or your formation documents (e.g., 'Tasty Tacoma, LLC').
COMMON MISTAKE: Using the DBA/trade name instead of the formal legal entity name; misspelling or omitting the legal suffix (LLC, Inc., LP).
State your business entity type as recognized by the state, such as 'Limited Liability Company (LLC)', 'Corporation', 'Sole Proprietorship', or 'Partnership'.
COMMON MISTAKE: Using informal terms like 'family business' or 'small business' instead of the precise legal structure.
Enter the name you are 'Doing Business As' (DBA), which is the public-facing name of your restaurant (e.g., 'Sunset Grill'). Leave blank if your legal name is also your trade name.
COMMON MISTAKE: Confusing this with the legal name or entering a name that is not registered with the county auditor if required locally.
Provide the complete street address where your restaurant is physically located and operates, including suite or unit number if applicable. Use the official address recognized by the local post office.
COMMON MISTAKE: Using a P.O. Box, a personal home address, or an incorrect/unofficial version of the street address.
Enter the address where you wish to receive official mail from the state. This can be a P.O. Box or a different physical location from your business address.
COMMON MISTAKE: Leaving it blank or entering 'Same as physical address' instead of writing out the complete address again.
For sole proprietorships, enter the individual owner's full legal name. For LLCs or corporations, enter the name of the authorized representative or member filing the application.
COMMON MISTAKE: For an LLC, listing the business name instead of a responsible individual's name, or using a nickname instead of a legal first and last name.
Enter the 9-digit Employer Identification Number (EIN) issued by the IRS for your business entity, or your Social Security Number (SSN) if you are a sole proprietor with no employees.
COMMON MISTAKE: Entering an incorrect or formatted number (e.g., using dashes: 12-3456789), or providing an EIN for a different, unrelated business entity.
Provide a direct, working phone number for the business, ideally one that is answered during standard business hours. Use the standard 10-digit format (e.g., 2535551234).
COMMON MISTAKE: Providing a personal cell number without identifying it as the business line, or entering a disconnected or invalid number.
Enter a professional email address that is monitored regularly, as the Washington Department of Revenue will send your UBI number and important tax notices here.
COMMON MISTAKE: Using a personal, informal, or rarely checked email address, or one with typos that will bounce.
Enter the date you began or will begin conducting business in Washington. For new restaurants, this is your planned opening date. Use the MM/DD/YYYY format.
COMMON MISTAKE: Entering the date the LLC was formed instead of the date revenue-generating activity starts, or using an incorrect format (e.g., writing 'June 1st').

Selecting an inaccurate 'Business Structure' (e.g., Sole Proprietorship vs LLC) is a common error that triggers review delays. The Washington Department of Revenue uses this classification to assign correct tax obligations. If you incorrectly list your LLC as a Sole Proprietorship, your application will be flagged, requiring a manual correction that typically adds 1-2 weeks to your licensing timeline. Avoid this by confirming your official legal structure with your formation documents before filing.
Failing to enter a NAICS (North American Industry Classification System) code, or choosing an inappropriate one for a restaurant, leads to processing holds. The state uses this code to determine your industry-specific tax and reporting requirements. For example, using a generic 'Retail Trade' code instead of the specific '722511 - Full-Service Restaurants' code can result in incorrect tax registration, requiring a follow-up submission to resolve. This mistake adds an average of 5 business days to the process.
Entering a P.O. Box or a home address as the 'Principal Place of Business' physical location, or having mismatched addresses across sections, is a high rejection risk. Washington requires a verifiable street address for the primary business location for licensing and tax jurisdiction. Providing a P.O. Box will cause an automatic rejection, forcing a re-submission that delays your UBI issuance by 2-3 weeks. Ensure all address fields match the restaurant's exact street address.

Before you begin, compile your business's legal structure details, all owners' Social Security Numbers or ITINs, NAICS code (find yours on the U.S. Census Bureau site), start date, and physical address. Have your bank account or credit card ready for the $19 government filing fee. Applications stall most often from incorrect NAICS code selection or missing owner identification.
Apply through the Washington State Department of Revenue's secure 'My DOR' portal. The online form has about 40 fields, covering business activities, locations, and ownership. Answer all questions; the 'Doing Business As' (DBA) name field is optional but crucial if your legal name differs from your trade name. Submitting with a DBA requires a separate registration with the Secretary of State.
DOR reviews your application, which triggers automatic registration for applicable state taxes like B&O (Business & Occupation) and sales tax. This step isn't an approval gate for the UBI itself but is where your tax account is established. If you selected complex activities or multiple locations, this internal routing can add time.
Applications go to the Washington secretary of state. Local procedures and fees may vary — select your city below.

See All RequirementsProcessing timelines for a Washington State Business License (UBI Number) vary significantly, typically ranging from a few days to several weeks. This depends on the application method and whether other registrations are involved. For example, if you need to concurrently register your business entity by filing Articles of Organization (LLC) or Articles of Incorporation (Corporation), the total timeline will be longer. Contact the Washington State Department of Revenue to confirm current processing estimates.
The government filing fee for the initial Washington State Business License (UBI Number) is $0–$0, according to the Washington State Department of Revenue. There is no base charge for obtaining the UBI, which is your account registration number with the state. However, this registration may trigger other requirements with separate fees, such as the annual Annual Report Filing. Not legal advice — verify with the Washington State Department of Revenue.
No, you cannot transfer a Washington State Business License (UBI Number) to a new location because the UBI is tied to your specific business entity. If you move your restaurant to a new address, you must update your business location with the Washington State Department of Revenue and the city. You will likely need to apply for a new local permit, such as the City Business License/Registration in Tacoma, using your existing UBI.
The UBI number itself does not expire or require renewal; it is your permanent state tax account identifier. However, you are required to renew your associated business license annually with the Washington State Department of Revenue and pay any associated fees for the license renewal. Failure to file your Annual Report Filing or renew your license on time can result in penalties and account suspension.
There is typically no physical inspection conducted by the Washington State Department of Revenue solely for obtaining a UBI number. The UBI is an administrative registration for tax purposes. However, opening a restaurant in Tacoma will trigger mandatory pre-opening inspections for other permits, such as the Certificate of Occupancy and health department approvals, which are separate from the state business license process.
