Who needs to register for a Hawaii Trade Name?

More information about the laws behind Trade Name registration can be found in Hawaii Statutes § 482-2,1 but it is voluntary to register for a fictitious business name in Hawaii.  There are a few reasons a business may want to register.  

A sole proprietorship and general partnership are the most common type of business structure to register for a Hawaii DBA. By default, the name of a sole proprietorship and general partnership is the owner(s) legal name. But, unlike most states, it is optional for a Hawaii business to register for a Trade Name.

Even though this is an optional registration, there are a few reasons that many sole proprietors or partnerships will want to register for a Trade Name:

  • Proves that small business exists.
  • Banks, merchant processors, and vendors may require one.
  • No other business can register the same name or obtain a trademark for that name in Hawaii.

A corporation, Limited Liability Company, or Limited Liability Partnership won’t typically register for a Hawaii DBA since a unique entity name is created during the entity formation process. However, some will want to register for a DBA if they have another business or brand name they want to operate in addition to the legal name of the business. This can allow multiple businesses to operate with the liability protection of a Hawaii corporation or Limited Liability Company without having to form another entity.

Steps to Register a Hawaii Trade Name?

Step 1: Check Available Names

In Hawaii, Trade Names are registered by the Hawaii Department of Commerce and Consumer Affairs (DCCA), Business Registration Division. To register a name, it must be unique and not similar to other registered names. To find out if the name you want is available, first do a Hawaii business name search on the DCCA website.

Additionally, applicants need to search the local phone directories of each island, the city directory, and the Hawaii Department of Taxation to verify no other business is using the name they want to register. 

Something to note is that if a business name isn’t used by the applicant for 365 consecutive days, the Trade Name may be revoked and available for anyone to register.

Step 2: Fill out and File the Trade Name Form

After verifying the name you want to use is available, the Application for Registration of Trade Name (Form T-1 ) and either submit online through the Hawaii Business Express website or by mailing the form

Information needed on the form includes:

  • Name and address of the applicant
  • Status of the applicant (type of business entity)
  • Name being requested
  • Nature of the business

Step 3: Submit the Form

You can file online or in person or submit the form along with the filing fee by email, mail, or fax. Email, mail, or fax filings must include the Trade Name form and credit card information.

In-person: Filings can be made at a Hawaii Business Action Center.
