Why You Need a Washington Sales Tax Registration
A Washington Sales Tax Registration is legally required for any business engaging in retail sales, leases, or rentals of tangible personal property within Spokane and Washington state. The requirement is mandated by the Washington Department of Revenue under RCW Title 82, the state's tax code governing retail sales tax, use tax, and business and occupation (B&O) tax. You must register before making your first taxable sale. This registration legally authorizes your business to collect sales tax from customers on behalf of the state and remit those funds. Operating without this registration means you are illegally collecting tax you have no authority to charge, creating significant liability.
Failure to obtain and maintain a valid registration carries serious, escalating consequences:
- Late filing and payment penalties: The Department of Revenue assesses penalties, typically 1-5% per month, on any unpaid tax due. Interest is also charged on the outstanding balance from the original due date.
- License and operational jeopardy: Persistent non-compliance can lead to the revocation of your business license, effectively shutting down operations. In severe cases of deliberate fraud, the state may pursue criminal prosecution.
- Business and financial impacts: Unresolved tax debt can lead to liens against your business assets, damage your credit, and violate terms in commercial leases or loan agreements that require you to maintain all necessary licenses in good standing.
Legal code: State tax code, sales/use tax statutes, withholding requirements
Recent update: As of 2026, the Washington Department of Revenue has integrated its business licensing and tax systems more closely, requiring consistency between your Unified Business Identifier (UBI) and all tax registrations.

188 of 226 auto-filledLegal Entity/Owner Name
textEnter the official, registered name of your business as it appears on your Secretary of State or Department of Revenue filings. For a sole proprietorship, enter your full legal name.
COMMON MISTAKE: Entering a 'doing business as' (DBA) name here instead of the registered legal name, which can cause the application to be rejected as mismatched against state business records.
Unified Business Identifier (UBI)
textEnter your Washington state-issued 9-digit UBI number, which is also your business registration number from the Secretary of State or Department of Revenue.
COMMON MISTAKE: Leaving this blank for a new business (a UBI is required to register for taxes), or entering a federal EIN, which is a different identifier and will not be accepted.
Federal Employer Identification Number (FEIN)
textEnter your 9-digit Employer Identification Number issued by the IRS. If you are a sole proprietor without employees, you may use your Social Security Number, but an EIN is strongly recommended.
COMMON MISTAKE: Transposing digits or using an outdated EIN from a previous business entity, which will cause a mismatch during federal verification.
Ownership structure - Sole Proprietorship
textCheck this box only if your business is owned and operated by one individual, with no legal distinction between the owner and the business entity.
COMMON MISTAKE: A sole proprietor incorrectly checking the 'Corporation' or 'LLC' box, which misrepresents the business's tax and liability structure and can invalidate the application.
Ownership structure - Corporation
textCheck this box only if your business is a C-Corp or S-Corp formally incorporated and registered with the Washington Secretary of State.
Ownership structure - General Partnership
textCheck this box only if your business is a partnership where all partners share equally in management, profits, and liability.
Ownership structure - Limited Partnership
textCheck this box only if your business is a partnership with at least one general partner (with liability) and one limited partner (with liability limited to their investment).
Ownership structure - LLC (Member-Managed)
textCheck this box only if your business is a Limited Liability Company where all members (owners) participate in the day-to-day management decisions.
COMMON MISTAKE: Confusing this with 'Manager-Managed' LLC; selecting the wrong management type creates a discrepancy with the LLC's official operating agreement on file with the state.
Ownership structure - LLC (Manager-Managed)
textCheck this box only if your business is a Limited Liability Company where appointed managers (who may or may not be members) handle daily operations.
COMMON MISTAKE: Confusing this with 'Member-Managed' LLC; selecting the wrong management type creates a discrepancy with the LLC's official operating agreement on file with the state.
Ownership structure - Limited Liability Partnership (LLP)
textCheck this box only if your business is a formal partnership, typically for licensed professionals, where partners have limited personal liability.

Top 5 Washington Sales Tax Registration Mistakes
1. Choosing the Wrong Registration Type for a Restaurant
Selecting the incorrect Business Activity Code (BAC) at the top of the application is the #1 cause of processing delays. In Spokane, restaurants selling both food and alcohol need at least two codes: one for the primary food service activity and another for alcohol sales under the 'Liquor by the Drink' classification. Using only a generic 'Restaurant' code triggers a manual review by the Washington Department of Revenue, as it doesn't account for taxable alcohol revenue, adding 2–3 weeks to your approval timeline. Ensure you select all applicable codes based on your exact menu and service model.
2. Entering Personal Information Instead of Business Entity Details
Applicants often enter their personal Social Security Number (SSN) and home address in the business information fields, especially for sole proprietorships. Washington's application requires the business's legal name, federal EIN (if applicable), and the restaurant's physical 'place of business' address in Spokane. Submitting with an SSN instead of an EIN or using a home address for the business location will result in immediate rejection, as the Department of Revenue cannot link the tax account to the correct business entity. Start with your official business registration documents from the Secretary of State to get these details right.
3. Miscalculating Projected Sales & Reporting Frequency
Underestimating or overestimating monthly taxable sales leads to an incorrect tax reporting frequency assignment (monthly, quarterly, or annually). The Washington DOR uses your projection to set filing deadlines and determine if you need to remit taxes monthly. If you project sales at $7,000/month but your actual first-month sales are $28,000, you may be assigned an annual reporting frequency, causing you to accrue large, unexpected tax liabilities without a monthly payment schedule. Provide a realistic, data-backed estimate based on your business plan to avoid this costly administrative error.

Gather Business and Financial Information
Collect your Business Unified Identification Number (UBI), Federal EIN, NAICS code, articles of incorporation (if incorporated), and detailed financial projections for monthly taxable sales. You'll also need your personal SSN or ITIN for owners/officers. Applications submitted without a NAICS code or with mismatched UBI/EIN information are a top cause of manual review delays at the Washington Department of Revenue.
Complete Online Application via DOR's "My DOR"
Log into the Washington Department of Revenue's "My DOR" system to complete the Business License Application, which includes sales tax registration. This single application registers you for multiple state taxes. You must select your business location's jurisdiction (Spokane city and Spokane County) for accurate local tax rates and specify your primary business activity. Nearly all applications are now filed this way—paper filings add 2+ weeks to the processing timeline.
Undergo Department of Revenue Review
The DOR reviews your application for completeness and assigns your business a 9-digit Unified Business Identifier (UBI), which serves as your tax registration number. This review verifies your reported NAICS code, projected sales volume for tax reporting frequency (monthly, quarterly, or annually), and ensures you've selected all applicable local jurisdictions (Spokane city tax is mandatory for businesses within city limits). Missing jurisdiction selections are a common rejection reason.

See All RequirementsProcessing time varies. According to the Washington State Department of Revenue, online applications for a new Business License (which includes the tax registration) can be approved immediately. Paper applications mailed to Olympia can take several weeks. The City of Spokane itself does not process this registration, but you will still need a local City Business License/Registration, which has its own timeline.
The state government filing fee is $0. Washington does not charge a fee to apply for a Business License and register for sales tax. However, you may need to pay other fees, such as those for your local Spokane business license, a Certificate of Occupancy, or any required professional registrations. Not legal advice — verify all costs with the Washington Department of Revenue.
No, you cannot simply transfer the registration. You must update your business address and location information with the Washington Department of Revenue through their My DOR account portal. If you move within Spokane, you'll also need to update your Spokane city business license separately. Operating from an unregistered location can result in penalties for filing returns with incorrect information.
Your Washington Business License, which authorizes you to collect sales tax, is valid for one year and must be renewed annually. Renewal notices are typically sent by the Department of Revenue about 45 days before expiration. The license must be kept current as long as you have taxable sales. Failure to renew can lead to license suspension and penalties, and may affect your ability to maintain other permits.
There is no physical inspection for a Washington Sales Tax Registration. The "inspection" is a review of your application data. The Department of Revenue verifies your business structure, location, and NAICS code to ensure proper tax classification. Their primary enforcement is through auditing your sales tax returns. For physical inspections related to your location, you'll likely need a Certificate of Occupancy from the City of Spokane.
