Washington Business Name Change

Are you thinking about how to change a business name in Washington? While “out with the old in with the new” is a timeworn saying, sometimes it’s the right thing to do. A new business name can revamp a waning company or add a little more sparkle to your star as it rises in popularity.

If you’re thinking about a business name change in Washington, we’ve got you covered. The first thing you need to do to change a limited liability company (LLC) or a corporation name is file paperwork with the State of Washington. When you file name change paperwork, you keep your business legally compliant.

To finalize a business name change in Washington, you’ll need to submit amendments to your business formation documents: an Amended Certificate of Formation (for LLCs) or an Articles of Amendment of a Profit Corporation Certificate (for corporations). Have you been meaning to file but haven’t found the time? We can register your amendment forms for you with our Amendment Filing Service.

3.) File your Washington amendment 

Once you’re ready to file your amendment, you can download an Amended Certificate of Formation of an LLC form or an Articles of Amendment of a Profit Corporation form, fill it out, and mail it with a fee to P.O. Box 40234, Olympia, WA 98504-0234, or send it by courier to 801 Capitol Way South, Olympia, WA 98501-1126. You may also fill out and submit an amendment form and fee on the Washington Secretary of State Business page online.

Or we can take care of your name change documents for you. Let us file your amendment so you have more time to share your new business name with the world.

After You Change Your Business Name

Nearly all businesses have licenses and permits listed with various local and federal government branches. Be sure to contact the Washington offices associated with those permits. For instance, you can visit the Washington Office of the Insurance Commissioner to learn how to change your business name on their forms.

Now that you’ve registered a new business name change in Washington, it’s time to notify the IRS. Be sure to visit the IRS website for specific business name change requirements. 

And don’t forget to change your business’s branding so it displays your new company name and logo. Remember to change all your business forms, signage, and website too. Then contact your website administrators and ask them to redirect your site to your new domain if necessary.

  1. What's the difference between a doing-business-as (DBA) name and business name? 

    A DBA allows sole proprietorships to conduct business under a name different from its legal name. Companies and corporations already have a separate name as part of their business or product identity. Like LLC and corporate name changes, however, a DBA must still be registered with the Washington State Business Licensing Service.

  2. Do I have to change my business name if I have a DBA name? 

    In Washington, you don’t have to change your business name if you use a DBA name. A DBA name isn’t your legal business name, but a commercial one. Imagine it more as the outward face of your business.

  3. How do I register my business name in Washington? 

    Go to the Washington Department of Revenue and click on the “open a business” tab. From there, you’ll be able to read and complete all the steps needed to register your business name.

  4. How many amendments can I make to my business?

    You may file an amendment as many times as you need to as your business changes. Keep in mind that each time you file, fees apply.
