How to Get a DBA in Washington: Rules, Fees, and Filing Steps

If you want to operate your business under a name that is different from your legal business name, Washington requires you to register a trade name. Many business owners call this a DBA, which stands for “doing business as.” In Washington, the state term is trade name, but the idea is the same: it is the public name you use in the course of business.

A DBA can help you build a brand, open a business bank account, and create a name that tells customers what you do. It is also a practical tool for sole proprietors, partnerships, LLCs, and corporations that want to market under a different name than the one on their formation records.

What a DBA Means in Washington

A DBA does not create a separate legal entity. It does not replace your LLC, corporation, or sole proprietorship, and it does not change how your business is taxed. Instead, it functions as an alternate name that you use publicly.

Washington requires trade name registration for:

• A sole proprietor or partnership using a name other than the full legal name of the owner or owners
• A corporation, limited partnership, or LLC operating under a name different from the one registered with the Washington Secretary of State
• Any business using a name that is not its full legal name

That means a trade name is not just a branding choice. In many cases, it is a legal filing requirement.

Why Business Owners Register a DBA

A Washington DBA can serve several business goals:

• Branding: Use a name that is easier for customers to remember and understand
• Privacy: Keep a personal name out of day-to-day business use when operating as a sole proprietor or partnership
• Banking: Many banks want a trade name on file before opening a business account
• Expansion: Use different names for different products, services, or markets
• Organization: Separate one business line from another without forming a new company every time

For example, a freelance designer using her personal name may prefer a trade name that clearly describes her services. A growing LLC may also want a second brand name for a new product line.

How to Choose a Washington DBA Name

Before filing, choose a name that is practical, memorable, and available for use.

A strong trade name should:

• Reflect your business purpose
• Be easy to spell and search
• Avoid confusion with other brands in your market
• Work well on signs, websites, invoices, and social profiles

Washington recommends checking several sources before filing:

• The Department of Revenue business lookup database
• The Washington Secretary of State database for corporations and LLCs
• The U.S. Patent and Trademark Office for federal trademarks

These searches help you avoid obvious conflicts. They do not guarantee that a name is risk-free, but they are a smart first step.

If your business will operate beyond Washington, consider whether a trademark would better protect your brand. A trade name records your business name with the state. A trademark is designed to protect brand use in commerce.

How to Register a DBA in Washington

Washington registers trade names through the Business License Application. You can apply online through My DOR or by mail.

1. Confirm your business structure

If your business is a corporation, LLC, limited partnership, or LLP, Washington requires you to file with the Secretary of State before submitting the Business License Application. That step comes first for formal entities.

If you are a sole proprietor or general partnership, you typically proceed directly to the business license process if you want to use a name other than the owners’ full legal names.

2. Check whether the name is available

Search for similar or identical names before filing. This is especially important if your name sounds similar to an existing business or if you plan to brand nationally.

Use the state business lookup, the Secretary of State records, and trademark searches as part of your review.

3. File the Business License Application

When you file in My DOR, enter your DBA in the trade name section. Washington treats the DBA as a trade name to be added to your business license record.

You can also file by mail using the Business License Application and any supporting documents.

4. Pay the required fees

Washington charges:

• $5 for each trade name registered
• A nonrefundable Business License Application processing fee

The processing fee depends on the type of filing, so check the state’s current fee guidance before submitting your application.

5. Wait for approval and keep your records

Once the state processes your filing, your trade name becomes part of your business record. Keep a copy of the confirmation with your business documents, banking records, and formation files.

Does a Washington DBA Need to Be Renewed?

No. A Washington trade name remains registered indefinitely until you cancel it.

That is one of the simpler parts of the process. You do not need to file a routine renewal just to keep the name active.

How to Change or Cancel a Trade Name

If you decide to update or stop using your trade name, Washington provides straightforward options.

To change a DBA

You can update the trade name online or by mail. If filing by mail, use the Business Information Change form and indicate that you want to change the trade name.

To cancel a DBA

You can cancel online through My DOR or by paper using the Business Information Change form. Washington does not charge a fee to cancel a trade name.

If you are no longer using the name, canceling it keeps your records clean and avoids confusion with customers, vendors, and banks.

Does a DBA Protect My Business Name?

Not by itself.

Registering a trade name in Washington does not give you exclusive ownership of the name. Another business may still be able to use a similar name, especially outside your local market. A trade name also does not replace trademark protection.

If brand protection matters, consider whether a trademark is a better fit for your long-term strategy. Many businesses use both:

• A trade name for state registration and operations
• A trademark for brand protection

Common Questions About Washington DBAs

Do I need a DBA if I use my own name?

If you are a sole proprietor and you are using only your full legal name, you may not need a trade name. If you add any other name or branding, you usually do.

Can a business have more than one DBA?

Yes. Washington allows a business to register an unlimited number of trade names.

Is a DBA the same as an LLC?

No. An LLC is a legal business structure. A DBA is just a name used by the business.

Does a DBA affect taxes?

No. A DBA does not create a separate tax entity.

How long does a Washington DBA stay active?

It stays active until you cancel it.
