Registering a business name in Washington can be done in 3 ways. You can start your business as a separate entity of its own by registering as an LLC or Corporation, or you can file a DBA (known officially as a Trade Name) as a sole proprietor or general partnership. If you want federal recognition of your business name, you may also want to file a USPTO trademark.

You should determine your business name and have it registered prior to completing most other business filings, including:

  • Registering with the Washington State Department of Revenue (DOR) for a business license via the My DOR system, which is required for the collection of sales tax or hiring employees
  • Obtaining a professional or occupational license from the Washington State Department of Licensing
  • Get local business licenses and permits through the FileLocal website
  • Apply for an IRS Tax ID Number (EIN)
  • Open a separate bank account for your business

How much does it cost to Register a Business Name in Washington?

The cost to register a Washington business name varies depending on the type of registration:

  • Washington LLC cost: $200
  • Washington Corporation cost: $200
  • Washington DBA cost: $24

1. Check Business Name Availability

Before you dive into registering your name, you must ensure your chosen name is good to go. That means checking if it’s already being used or is too similar to other business names out there. This step is super important because it helps prevent problems like clashes with similar businesses or your Washington name registration being turned down. To do this properly, you should do three specific types of searches:

Start your Washington business name search with the help of professionals.

Trademark Search

Your first search should be for federal trademarks. Trademarks registered at the federal level provide the most legal protection. As a result, they override any registrations at the local or federal level, so it’s important to ensure that your name is not trademarked. If the business name you chose is the same or too similar to an existing trademark, come up with a new name.

To search the U.S. Patent and Trademark Office (USPTO) database, visit the Trademark Electronic Search System (TESS) page. Just be advised – the returned results can be overwhelming and hard to understand. Alternatively, you can use Trademark Engine’s Free Trademark Search, which provides results from TESS in an easier-to-use format.

Washington Business Name Search

After verifying that the business name you want isn’t a registered trademark, it’s time to move on to doing a Washington business name search. Use the Washington Corporations Search to search the Washington database of registered businesses.

Make sure you search more than just your exact business name, and you do some searches using either only parts of your name or wildcard characters. This is especially important because your name registration can be rejected if it’s too similar to an existing business.

Pro Tip: Pay close attention to if the business name you want to use was used in the past, even if it’s available now. Registering your business name using a name that was used in the past can cause a lot of problems when you try to get an EIN.

Using a previously registered name will often result in the online assistant rejecting your EIN application and returning reference number 101. This error happens when your name matches or is too close to a name that was already issued an EIN. If a business shows as being previously registered, they were also likely issued an EIN. If you get reference error 101, it will require that you call and fax your formation paperwork to the IRS, which is quite a headache.

Website Domain Search

Once you’ve verified you can use your business name, you should verify the matching website domain name is available. Most businesses will need some online presence, but even if you won’t build a website, you should register your domain name to prevent others from using it. You’ll also need it if you plan on using a matching business email address.

Domain Name and Business Email

You can use Namecheap to verify if your domain name is available. They also offer a business email service that’s free to try for the first 60 days when you purchase a domain.

2. Choose a Business Structure

When starting the process of registering your business name in Washington, you need to determine which business structure you’ll use. Your choice of business structure has many downline implications for your business and will change the process of how your business is registered. You should choose a business structure that matches the amount of liability risk, tax implications, and financing your business will require. If you can’t decide based on the information below, you can get more guidance by using our guide on Choosing a Business Structure, where you can get more in-depth information.

Recommended Business Structure:

Most new businesses benefit the most by starting as an LLC. You can have as many owners as needed and they provide tax and management flexibility. They have liability protection that sole proprietorships and general partnership lack and aren’t subject to double taxation (corporate income tax) like a corporation.

Consider using an LLC formation service to ensure your filing is completed correctly. Our list of the best LLC services can help you find the one that works best for you.

4. File a Trademark (Optional)

If you want to protect your business identity, consider filing for a trademark. A trademark can help safeguard your brand name and give you control over it. Unlike state registrations, trademarks offer federal-level protection nationwide.

While you can apply by yourself online, registering a trademark can be a complex and lengthy process. On average, it takes 7-9 months before a USPTO examining attorney reviews your application. You’ll need to properly prepare and submit your application to limit delays.

Consider seeking assistance from a qualified attorney or a trademark filing service to make the trademark registration process smoother. Their expertise can save you time and spare you the challenges involved in application submission and follow-ups.
