If you don’t know where to start, don’t worry. We’ll walk you through the types of business licenses and permits you might need for your Washington business and how our Business License Report service can help you get it done easily.

What is a business license?

Most businesses need some form of license or permit to operate. The exact applications you need to file depend on your location, industry, and business activities. It can sometimes feel like a wild goose chase when you are tracking down the information on what you need. 

Consider using our Business License Report Service to make the process less time-consuming and stressful. You’re going to have enough going on already when starting a new business. 

Step 1: Obtain a Washington State general business license

Not all states require businesses to obtain a general business license, but Washington does. This is typically referred to as a Master Business License and is necessary for many business tasks, including the following:

The application for your Washington State Master Business License is filed with the Business Licensing Service, which is part of the Department of Revenue. You can apply for your Washington business license online or via postal mail. Some business types are not eligible to apply online. These include: 

Applications completed online are typically processed within two days. A confirmation email is sent at the completion of processing. Postal mail applications can take up to 21 days to be processed. You can submit payment at the time of filing. 

Washington Business License vs. Registration 

Obtaining a business license isn’t the same as registering your business. Register your business with the state before submitting your Master Business License application. For your business to become an official entity, you must register formation documents with the Washington Secretary of State. Whether you choose to form a corporation, limited liability company, sole proprietorship, or another type of business depends on a number of factors. These may include preferred business structure, management style, tax obligations, industry, and more. 

Once you register the business, you’ll be assigned a unified business identifier (UBI) number. You need to have this number for your Washington business license application. 

Step 2: Obtain applicable federal licenses for your Washington business

Business licenses requirements are found at all levels of government. Check this list to find out more about the industries that are federally regulated and determine if your Washington business fits into one of these categories. If so, you can contact the listed agency for more information. 

If you aren’t sure whether your company falls into one of the above categories, the agency listed will be able to provide more information.

Step 3: Check for Washington permits and licenses

Washington state-level licenses and permits are called endorsements. Use the Department of Revenue Business Licensing Wizard tool as a first-stop to check for state licensing requirements. Licenses are industry-specific and regulated by various agencies. Some industries that may need state-level licenses include:

Step 4: Check for city or county for local licensing in Washington

There are 39 counties in Washington. Each county or municipality may have its own licensing and permitting requirements. It’s important to make sure you check with your county clerk’s office, local tax office, and any city administrators to make sure you fulfill all local licensing and permit requirements. 

Step 5: Search for applicable Washington professional licenses

If your profession has a specific education requirement in order to perform services, you probably need a professional license. Obtaining a professional license certifies that you have the knowledge, experience, and skills to perform your specific job. Professional licenses are important and usually issued by state boards specific to the occupation. Some licensed occupations include:

This is only a small sampling of professions that require specific licensure. Check the Washington State Department of Licensing for more information on professional licenses. 

Step 6: Obtain any other necessary Washington business licenses and permits

All businesses have varying degrees of regulation. Depending on what it is that you do, you may need a number of other licenses and permits. A massage therapist is going to have very different licensing requirements than a pharmaceutical manufacturer. 

Potential permits include:

This is not an exhaustive list, but these types of permits are common requirements.

Step 7: Apply for Washington home-based business licenses

Washington home-based businesses need to register with the state like any other business entity. Licensing and permits are issued by the municipality where the home is located. Each area has different stipulations regarding home-based businesses. Common rules pertain to the primary use of the residence, signage, parking, appointments, staffing, equipment, type of business, and other regulations. If you’re planning on opening a home-based business, contact your local government for more information on what you’re permitted to do and what documents need to be filed. 

Step 8: Maintain your Washington licensing

Failing to acquire and maintain all necessary Washington business licenses and permits could result in fines, penalties, legal disputes, and even an inability to operate in the state or municipality where the violation occurred. Most business licenses and permits must be renewed periodically. It’s important to keep track of what is due for renewal and when. All this compliance may seem overwhelming, but we can help.
