What is a DBA?

DBA is an acronym that means “doing business as.” The DBA meaning is when the name, also called a trade name or fictitious name, isn’t registered as an LLC or some other legal entity but is a legal business. 

Practically, using the DBA or a fictitious business name as a company name is when you call and promote your business under a different name other than the legal name or your own name. This is helpful for marketing but also offers legal protections and tax advantages to sole proprietors, a limited liability companies (LLC), and general partnerships.

How to search DBA names in Washington

No one can start running a business under a company name like a DBA. There are rules that states have about the name of your business, including Washington State. One of the biggest rules states have is that you can’t have a registered name that’s exactly like or too similar to another company name.

Potential business owners must check for name availability against a registered name even when picking a DBA name. Start with the state list from the Washington Secretary of State office, but you can also double-check local DBA names against business licenses at the county clerk’s office.

Be sure to check under general licenses, and corporate entity searches, and also check with the U.S. Patent and Trade Mark Office if you plan to launch a national company or have an invention.

Go to the Washington Clerk’s Secretary of State’s page

Once you are on the Secretary of State page, look for the free tool to check corporate entity listings. Put your name idea into the entity box. This is a free tool so you can check as many names as you want. Although there is a place to create an account, you don’t have to make one in order to use the tool located further down on the page.

Review the search results

The search will show you any exact matches or similar names to the name you want. You want your business name to be unique so you can do better marketing and not be confused with other businesses. However, the state doesn’t prevent anyone from using the same DBA name, even if it’s a registered name.

Register a name you like

When you find a unique name, you can go ahead and register it with the Washington Department of Revenue as a trade name. You must register a trade name if you have a sole proprietorship and are using any other name for business, if you are an LLC, limited partnership, or corporation using any name other than the legal name, or if you are any business using any other name other than the legal registered name.

You can register an unlimited number of trade names, each remaining registered indefinitely until you cancel it.

What comes next

Just because you have a registered trade name doesn’t mean you are ready to open your doors. There are several other things you must do at the state level to be ready to open for business in Washington. These are things that make sure you are cleared legally to do business. 

Open up a business checking account

Banks will allow those with DBA certificates to open up accounts under the DBA name. This should be one of the first things you should do for your new business to accept payments and pay for expenditures.

Get an EIN

This is a federal employer identification number associated with your business. This is important in filing taxes, hiring employees, and dealing with vendors. Most require it on contracts or other financial forms.

Check state tax requirements

Washington has a different set of tax requirements for businesses, so you should check where your DBA falls in the system. How you are taxed sometimes depends on whether you are a sole proprietor or a registered business like an LLC, but it’s always safe to check to make sure you’re aware of the requirements by clicking here.

Check with state insurance and hiring requirements

Some states are more strict than others when it comes to hiring practices and worker’s compensation for employees. Some require it for even part-time or family workers. Be sure to look here at Washington’s laws, so you stay within the standards. You should include liability insurance in your plan to have liability protection.

Set up your business goals and policies

A business plan makes good sense even for sole proprietors. Having a good, written business structure provides a reference whenever something comes up, whether it’s dealing with employees or customers.

Establish a marketing plan

A solid marketing plan for your new DBA can help your business go in the right direction from the state. A good marketing plan, including internet and local newspaper ads, will help you hit the ground running and be an avenue for growth. It helps establish your brand and keeps your DBA in front of the public.

Connect with resources for help

Washington State has plenty of resources to help small business owners in their startups. The Office of Commercialization at Washington State University has a list, but there is also Startup 365 from the Washington State Startup Small Business Training & Education Center and startup resources from the Foster School of Business.

If you plan to get an EIN, you can do so on the IRS website.

Who is a DBA best for? 

Sole proprietorships often use DBA names so they can separate their personal name from the business name to protect personal assets. General partnerships use it for the same reason, and so all partnerships can monitor business dealings. 

Any type of legal business entity can do business under a DBA, and many do it to build a branded image or because they have multiple niche businesses they wish to keep as separate legal entities. The idea is to keep a DBA name from the legal name, which can be a company name or a personal name. The name of the business is one of the most important things you can do.
