DBA Hawaii - Filing a Hawaii DBA is Easy, Follow These 2 Steps

Step 1: Start With a Hawaii DBA Name Search

If you haven't already, head over to the Hawaii Department of Commerce and Consumer Affairs website to make sure your trade name isn't taken by another registered Hawaii business. Your name can be similar to other business names, but it’s still a good practice to create a unique name.

TIP: Our business name generator tool is a great resource for entrepreneurs who are still working to create the perfect business name or website address. You can also use our free logo generator tool to make a logo yourself! No design experience necessary!

Hawaii also recommends checking with the Department of Taxation and searching local phone directories and Polk City Directories to see if your trade name has been used.

In Hawaii, your trade name should not include:

  • Any business entity suffix, such as LLC, Incorporated, Corp., etc unless the business is actually an LLC, corporation, or etc.
  • Any terms given to financial institutions, including: "bank," "banc," "banco," "banque," "banker," "trust company," "savings and loan association," "savings bank," "credit union" or other similar words.

You can find additional information regarding Hawaii business name rules and regulations here.

Next, a quick search on the U.S. Trademark Electronic Search System will tell you whether someone else has already trademarked your name.

Now would be the perfect time to make sure there’s a web domain available for your DBA as well.

DBAs don’t require insurance because DBAs aren't a business entity. However, the business entity that the DBA is under will need protection from losses that can happen naturally in the course of business, such as property damage or lawsuits.

You can transfer a trade name in Hawaii online or by filling out and returning this form. The fee is $10.

Is my Hawaii DBA protected from being used in other places?

There are some state-level laws that prevent DBAs that are too similar to existing ones from being used, but your name is not protected in Hawaii. It is possible to create a federal trademark for a DBA, which would offer stronger protection across state lines.

How many DBAs can I have?

You can have as many DBAs as you can afford to create and are able to keep track of. However, more isn’t necessarily better. Each one will come with additional incremental expense and paperwork, so you will want to make sure you have a good reason for each one you have.

Can a DBA get an EIN or Tax ID?

DBAs aren’t required to have a separate EIN because DBAs aren’t a business entity. The business entity that the DBA is under would have an EIN if an EIN is required.

To learn more about EINs and when you would need one for your business, read What is An EIN from our friends at TRUiC.

Can a DBA become an LLC?

Your DBA is just a name. A DBA is often confused with a sole proprietorship. If you mean “can my sole proprietorship become an LLC?” then the answer is “Yes. Absolutely.”

To learn how to form an LLC, visit our Form an LLC state guides.

Can a DBA have "Inc." in the name?

A DBA can only have "Inc." in the name if the business entity the DBA is attached to is a corporation.

How do I set up a DBA for a Rental Property?

It’s always best to consult an attorney. Usually, the best option is to form an LLC to protect your personal assets in the event of an issue with the rental property. Holding the rental property in your name and with a DBA will not afford you any protection.
