Washington State Department of Licensing Startup Guide

Starting a business in Washington usually means three core moves: form your entity with the Washington Secretary of State, get your state business license and tax accounts through the Department of Revenue, and check whether the Washington State Department of Licensing or another agency regulates your profession. Washington has no state income tax, but it does have business and occupation tax, sales tax, city endorsements, and industry licenses that can surprise first-time founders.

Here is the plain-English roadmap.

Registration

Most Washington founders start by choosing a legal structure, then registering with the Washington Secretary of State if they want an LLC, corporation, nonprofit, or limited partnership.

Common options are:

• Sole proprietorship: Easiest to start, but no liability separation. You may still need a state business license, city endorsement, trade name, tax account, or professional license.
• General partnership: Similar to a sole proprietorship, but with two or more owners. Use a written partnership agreement.
• Limited liability company, or LLC: The common choice for first-time founders who want liability protection and flexible tax treatment.
• Corporation: Often used when you plan to raise outside investment, issue stock, or build a more formal ownership structure.
• Nonprofit corporation: Used for charitable, educational, religious, or community purposes. State formation does not automatically create federal tax-exempt status.

For an LLC, the formation filing is generally called a Certificate of Formation. For a corporation, it is generally called Articles of Incorporation. These are filed with the Washington Secretary of State, Corporations and Charities Division.

Washington requires most registered entities to have a registered agent with a physical street address in Washington. This can be you, another individual, or a commercial registered agent. A P.O. box by itself is not enough.

Your business name must be distinguishable from existing Washington entities and must include the proper designator, such as “LLC,” “Limited Liability Company,” “Inc.,” or “Corporation,” depending on the entity type. If you are not ready to form yet, Washington allows name reservation for a limited period, typically 180 days, for a small filing fee. If you plan to operate under a public-facing name that is different from your legal entity name, you will usually register a trade name through Washington’s Business Licensing Service rather than through the Secretary of State.

Typical registration costs and timing:

After formation, Washington entities must file an annual report with the Secretary of State. Missing it can lead to late fees, administrative dissolution, and problems opening bank accounts or proving good standing.

Taxes

Washington is unusual because it has no personal income tax and no traditional corporate income tax. That does not mean your business is tax-free. Most Washington businesses deal with the business and occupation tax, commonly called B&O tax, plus sales tax if they sell taxable goods or services.

The main state tax agency is the Washington State Department of Revenue.

You will usually register with the Department of Revenue through the Business Licensing Service. This is the step that gives many businesses a Washington Unified Business Identifier, or UBI, and sets up state tax accounts. The UBI is a key number you will use with state agencies, banks, cities, and licensing bodies.

Important Washington tax items:

• Federal EIN: Get this from the IRS. Most LLCs, corporations, partnerships, and employers need one. Even if you are a single-member LLC, an EIN is usually useful for banking and vendor paperwork.
• B&O tax: This is a gross receipts tax, not a profit tax. Rates vary by classification, such as retailing, wholesaling, manufacturing, or service and other activities. Filing may be monthly, quarterly, or annually depending on your business volume.
• Sales tax: Washington’s state sales tax rate is 6.5%, and local rates are added on top. The total rate varies by location and is often meaningfully higher than the state rate alone. Washington generally uses destination-based sales tax sourcing for in-state sales.
• Use tax: If you buy taxable items without paying Washington sales tax, use tax may apply.
• Employer taxes: If you hire employees, you will likely register with the Washington Employment Security Department for unemployment insurance and with Washington State Department of Labor & Industries for workers’ compensation. Washington also has Paid Family and Medical Leave requirements administered through the Employment Security Department.
• No state payroll income tax withholding: Washington does not have state personal income tax withholding, but federal payroll taxes still apply.

Your filing cadence depends on the Department of Revenue’s assignment. Many new businesses start annual or quarterly, but businesses with higher tax volume may file monthly. Always read the filing frequency assigned to your account after registration.

Also check city-level taxes. Seattle, Tacoma, Bellevue, Bellingham, and other cities may have local business license taxes, square-footage taxes, or gross receipts requirements. Some city endorsements are handled through the state Business Licensing Service, while others require a separate local filing.

Licenses

Washington does not have one single license that covers every business activity. Instead, it uses a mix of state business licensing, city endorsements, and profession-specific licenses.

The first licensing stop for many founders is the Washington State Department of Revenue Business Licensing Service. This is where you apply for a Washington business license, register trade names, add many city endorsements, and notify the state that you will collect sales tax or hire employees.

The Washington State Department of Licensing is still important, but it is not the same thing as the Department of Revenue’s Business Licensing Service. The Department of Licensing handles many occupational and professional license programs and also manages driver and vehicle licensing. If your work is regulated by DOL, you may need approval before you can legally offer services.

Common Washington licensing agencies include:

• Washington State Department of Licensing: Real estate brokers, appraisers, cosmetology-related professions, notaries, some security-related licenses, and other professional programs.
• Washington State Department of Labor & Industries: Contractor registration, electrical licensing, plumber certification, elevator work, workers’ compensation accounts, and workplace safety.
• Washington State Department of Health: Health care providers, massage therapists, food worker cards in coordination with local health departments, and many health-related professions.
• Washington State Liquor and Cannabis Board: Liquor licenses, cannabis licenses, and alcohol service compliance.
• Washington State Department of Agriculture: Food processors, dairies, plant-related businesses, pesticides, weights and measures, and certain agriculture-related operations.
• Department of Children, Youth, and Families: Child care licensing.
• Department of Financial Institutions: Some lenders, money transmitters, investment advisers, and financial services businesses.

A simple retail shop may need a state business license, sales tax registration, and a city endorsement. A restaurant may need all of that plus local health approval, food worker cards, fire inspection, signage approval, and possibly a liquor license. A contractor may need a business license, contractor registration through Labor & Industries, bond and insurance proof, and local permits for jobs.

Before you sell, ask three questions:

1. Does my business activity require a state license?
2. Does my city require a local license or endorsement?
3. Does my industry require approval before opening, serving clients, or advertising?

Permits

Permits are usually local. Your city or county decides whether your location, signage, construction, food handling, or home-based business is allowed.

Common Washington permits include:

• Zoning approval: Confirms your business activity is allowed at your address. This matters for storefronts, warehouses, studios, restaurants, child care, manufacturing, and home businesses.
• Home occupation permit: Many cities allow home businesses but restrict customer visits, employees, parking, noise, signs, storage, and deliveries.
• Building permit: Needed for remodels, structural work, electrical, plumbing, mechanical changes, and many tenant improvements.
• Fire inspection or fire permit: Common for restaurants, assembly spaces, day cares, salons, warehouses, and businesses using hazardous materials.
• Health permit: Required for restaurants, food trucks, caterers, coffee stands, mobile food units, and some personal services. Local county health departments usually handle this.
• Sign permit: Needed before installing exterior signs, window signs above certain limits, illuminated signs, or monument signs.
• Right-of-way or sidewalk permit: Needed for sidewalk seating, street vending, construction staging, or signs placed in public space.
• Environmental permits: May be needed for auto shops, manufacturing, stormwater discharge, hazardous waste, shoreline activity, or air emissions. The Washington State Department of Ecology may be involved.

Do not sign a long lease until you confirm zoning and permit feasibility. In Washington cities, a space can be beautiful and still not be approved for your use without expensive upgrades.

Insurance

Washington requires certain coverage once you hire employees or put vehicles on the road.

If you have employees, you generally need workers’ compensation coverage through the Washington State Department of Labor & Industries. Washington’s system is state-administered for most employers, and rates depend on worker classification and payroll. Some owners, officers, members, and sole proprietors may be exempt or may elect coverage, so confirm your specific setup with Labor & Industries.

If your business owns or uses vehicles, you need commercial auto insurance or appropriate business use coverage. Personal auto policies often exclude business use, deliveries, rideshare, hauling tools, or employee driving.

Common policies Washington founders carry include:

• General liability insurance: Covers many third-party injury or property damage claims.
• Professional liability, or errors and omissions: Important for consultants, designers, accountants, coaches, tech firms, and licensed professionals.
• Commercial property insurance: Covers equipment, inventory, furniture, improvements, and supplies.
• Business owner’s policy: Bundles general liability and property coverage for many small businesses.
• Cyber liability: Useful if you store customer data, take online payments, or run a software or ecommerce business.
• Product liability: Important if you make, import, distribute, or sell physical products.

Landlords, lenders, marketplaces, and clients may require certificates of insurance before you can start work.

Banking

Open a separate business bank account before taking your first payment. This keeps your books clean, supports liability separation, and makes tax filing easier.

For a Washington LLC or corporation, banks commonly ask for:

• Your EIN from the IRS
• Your Washington UBI number, if already issued
• Certificate of Formation or Articles of Incorporation
• Operating agreement or bylaws
• Business license or city endorsement, if applicable
• Trade name registration, if the account uses a DBA
• Photo ID and personal information for owners or authorized signers
• Beneficial ownership information required by bank compliance rules

Look for a bank or credit union that fits how you will operate. If you are cash-heavy, ask about deposit limits and branch access. If you are a contractor, ask about mobile deposits and same-day ACH. If you sell online, confirm integrations with your payment processor and bookkeeping software. Local Washington credit unions and community banks can be helpful when you want relationship banking, while national banks may be more convenient if you operate across states.

Do not mix personal and business spending. Pay yourself through owner draws, payroll, or distributions depending on your entity and tax election. Keep receipts and categorize expenses from day one.

State Resources

These are the real Washington agencies and programs most founders use:

• Washington Secretary of State, Corporations and Charities Division: Forms LLCs, corporations, nonprofits, and other registered entities. Also handles annual reports and certificates of status.
• Washington State Department of Revenue: Administers B&O tax, sales tax, reseller permits, excise taxes, and the Business Licensing Service.
• Washington State Department of Licensing: Handles many professional and occupational licensing programs, plus driver and vehicle licensing. Check this agency if your profession is regulated.

• Washington Employment Security Department: Handles unemployment insurance and Paid Family and Medical Leave reporting for employers.
