Hawaii handles business name registration differently than most states. It uses the term "trade name" instead of "DBA," and registration is optional, not legally required. This guide explains what that means, who should still file, and how to complete the process through every available submission method.
What does DBA mean in Hawaii?
DBA stands for "doing business as," a term used across most of the U.S. to describe operating under a name other than your legal name. Hawaii uses the official term "trade name" instead. The concept is identical: a sole proprietor named Leilani Akana, for example, might operate publicly as Aloha Bookkeeping Services.
Trade name vs. legal business name vs. trademark in Hawaii
| What it is | What legal protection it provides | Who files it and where | |
|---|---|---|---|
| Trade name registration | A public record that you are operating under a name other than your legal name | Creates public notice of your name use in Hawaii; does not grant exclusive rights | Any business owner; filed with Hawaii DCCA Business Registration Division (BREG) |
| Legal entity formation | The formal creation of a business structure, such as an LLC, corporation, or partnership, with a registered legal name | Establishes your legal business name with the state; provides liability separation for LLCs and corporations | Business owner; filed with DCCA BREG as part of entity formation |
| Federal trademark registration | A federal registration of a word, phrase, or logo that identifies your goods or services in the marketplace | Grants nationwide exclusive rights to use the mark in your industry; the strongest available name protection | Business or individual; filed with the U.S. Patent and Trademark Office (USPTO) |
Registering a Hawaii trade name does not create a new legal entity. It also does not give you trademark rights. If two businesses register similar trade names, the registration alone does not decide who has the legal right to use the name. For exclusive, enforceable protection, a federal trademark is the right next step.
Do you need to register a trade name in Hawaii?
No. Hawaii law does not require you to register a trade name before using one in commerce. That said, most banks require a registered trade name before opening a business checking account in that name. Filing also creates a public record that can deter others from using the same name and signals legitimacy to customers, vendors, and partners who may search the DCCA database before doing business with you.
Who should file a Hawaii trade name?
Any business type can file. The deciding factor is whether you plan to operate under a name that differs from your legal name or your entity's registered name.
Sole proprietors
If you operate under your own full legal name, no registration is needed. But if you want to do business as "North Shore Landscaping," a trade name registration creates the public record that banks and customers expect. For a sole proprietor, a trade name is also the only formal way to establish a business identity separate from your personal name without forming an LLC or corporation.
LLCs
An LLC's registered name is its legal name on file with BREG. If Hilo Surf Collective LLC wants to market itself as "Hilo Surf" or launch a second brand called "Wave Ready Rentals," filing a trade name bridges the gap between what the state has on record and what customers actually see.
If you're still working through starting an LLC in Hawaii, factor trade name planning into that early stage rather than treating it as an afterthought.
Corporations
A corporation registered as "Kona Coastal Enterprises, Inc." might promote one product line under an entirely different public-facing name. Filing a trade name formally connects that operating name to the legal entity on record.
If you're considering forming a Hawaii corporation, working out your trade name strategy alongside entity formation saves extra steps down the road.
Partnerships
General partnerships should file a trade name if they operate under any name other than the combined surnames of all partners. A partnership run by the Torres and Yamamoto families can use "Torres & Yamamoto" without registering, but "Oahu Event Group" requires a trade name on file with BREG.
How to check if a Hawaii trade name is available
Before you submit your application, confirm that your proposed trade name isn't already registered and that it meets Hawaii's naming requirements. BREG runs its own check when you file, but discovering a conflict after submission wastes time and fees.
- Go to the DCCA Business Name Search tool. The Hawaii Business Express portal hosts a public name search database. You can also search for available Hawaii business names using LegalZoom's tool.
- Search your exact proposed name. Review every result, not just exact matches. BREG evaluates "substantially identical" names, meaning minor variations may still trigger a rejection.
- Search variations of your name. Try alternate spellings, phonetic equivalents, and versions with or without "Hawaii" or "Hawaiian."
- Check beyond the BREG database. The state recommends also checking the Department of Taxation website and local business directories. Because registration is voluntary, a business could be actively using a name without ever having registered it with BREG — and an unregistered prior user can still have ownership rights.
- Confirm your name meets Hawaii's naming rules. Even a name with no existing registrations can be rejected if it violates specific restrictions.
Hawaii trade name naming rules and common rejection reasons
Hawaii's naming rules are spelled out in Section 16-36-15 of the Hawaii Administrative Rules. A proposed name that is "substantially identical" to a registered name will be rejected, and that term covers more ground than most applicants expect.
Your application will likely be rejected if any of the following apply.
- The name sounds the same as an existing registration, even if spelled differently.
- The only difference is adding "Hawaii" or "Hawaiian." Names like "Omni, Inc." and "Omni of Hawaii, Inc." are considered substantially identical. The same applies when "Hawaii" or "Hawaiian" appears at the beginning.
- The only difference is a plural, possessive, or common article. Adding or removing a possessive "s," a plural, or small connecting words like "and," "the," or "of" does not distinguish a name from an existing registration.
- The name implies a government connection. Names suggesting affiliation with a government agency will be denied unless that agency has specifically authorized the use.
- The name uses banking or financial terms without authorization. Such terms cannot be included unless approved by the Hawaii State Commissioner of Financial Institutions.
- The name is a purely geographic term or landmark. Names like "Honolulu," "Diamond Head," "Pearl Harbor," or "King Street" cannot be registered, even with a business entity suffix added.
- The name contains deceptive language.

How to register a trade name in Hawaii: Step-by-step
All Hawaii trade name registrations go through BREG. The basic process is the same regardless of submission method: search for availability, complete Form T-1 (the Application for Registration of Trade Name), pay the filing fee, and wait for confirmation.
BREG accepts four submission methods: online, by mail, by fax, and in person.
Filing online through Hawaii Business Express
- Create or log in to your Hawaii Business Express account at hbe.ehawaii.gov.
- Complete Form T-1. Enter your proposed trade name, legal name or entity name, business address, business type, and a brief description of your business.
- Pay by credit card. BREG accepts Visa, MasterCard, Discover, American Express, Diners Club, and JCB.
- Receive your confirmation. Online filing typically results in quicker review times. Your account also lets you check filing status, view deadlines, and purchase documents after submission.
Filing by mail
- Download and complete Form T-1 from the BREG website. Paper filings must be typewritten or printed and signed in black ink.
- Make your check payable to the Department of Commerce and Consumer Affairs for the exact amount. A $25.00 fee applies to dishonored checks.
- Mail your form and payment to P.O. Box 40, Honolulu, HI 96810. Processing times are longer than online filing.
Filing by fax
- Complete Form T-1 using the same requirements as mail: typewritten or printed, signed in black ink, on standard letter-sized paper.
- Include credit card payment information with your fax: card number, card type, cardholder name, expiration date, CVV code, charge amount, whether you want expedited or standard review, a contact phone number, and an email address.
- Send your fax to (808) 586-2733. Processing times are similar to mail.
Filing in person
- Complete Form T-1 before you arrive.
- Bring payment by check, money order, or credit card.
- Visit the BREG office at the King Kalakaua Building, 335 Merchant Street, Room 201, Honolulu, Hawaii 96813. Hours are Monday through Friday, 7:45 AM to 4:30 PM Hawaii Standard Time, except state holidays.
In-person filing gives you the best chance of same-day processing, since BREG staff can review your form at the window and flag issues on the spot.
Hawaii trade name filing fees and processing times
The standard filing fee for Form T-1 is $50.00, with an optional expedited service fee of $20.00. Filing fees are not refundable.
| Filing method | Standard fee | Expedited fee | Estimated processing time |
|---|---|---|---|
| Online (Hawaii Business Express) | $50.00 | +$20.00 | Often same day or next business day |
| $50.00 | +$20.00 | Longer; delays possible depending on volume | |
| Fax | $50.00 | +$20.00 | Similar to mail |
| In person | $50.00 | +$20.00 | Same day or near-immediate at the service window |
Fees are current as of publication but subject to change. Confirm at cca.hawaii.gov/breg/ before filing.
The $50.00 fee covers the full five-year registration term. A certified copy costs $10.00 plus $0.25 per page, with an additional State Archives fee of $1.00.
A note on current processing times: BREG is transitioning to a new IT system, causing delays for paper-based submissions. Online filing is the most reliable option for speed right now.
A few other things to know:
- Expedited review applies to the review step, not the delivery method. For the fastest outcome, combine online filing with the expedited fee.
- Errors mean refiling. If your application contains mistakes or your name conflicts with an existing registration, BREG will reject it and you'll need to refile, restarting the clock and paying the fee again. A thorough name search before you submit is the most effective way to avoid that outcome.
How to renew, amend, or cancel a Hawaii trade name
Your Hawaii trade name registration is valid for five years. At the end of that period, or anytime during the six months before it expires, you need to reregister to keep the name active.
Renewing your Hawaii trade name
- Know your renewal window. You can renew within six months before the expiration date. If your trade name has already expired, you must treat it as a new filing — paying the full fee again with no guarantee the name is still available.
- File a new Form T-1. Check the renewal box rather than the new registration box. The fee is $50.00, with an optional $20.00 expedited service fee.
- Choose your submission method. All four methods are available. In Hawaii Business Express, log in, go to Manage, and select "Trade Names & Marks."
Tip: Hawaii Business Express offers a reminder service that sends email or text notifications before your renewal deadline, for $2.50 per trade name for the five-year period.
Under Section 482-6 of the Hawaii Revised Statutes, if a registered trade name goes unused for 365 consecutive days, it becomes subject to revocation by petition. Keeping your registration current and actively using the name protects against a third party challenging it on nonuse grounds.
Amending your Hawaii trade name
- Log in to Hawaii Business Express and select the trade name you'd like to update.
- Select the appropriate change form. Available changes typically include updating the registrant's address and contact information.
- Submit through the Manage workflow.
Important: If you want to change the trade name itself, that's not an amendment — it requires a new Form T-1 filing. If you no longer intend to use the old name, cancel that registration separately.
If the trade name was transferred to a new owner, BREG provides Form T-4 (Assignment of Print, Label, Trademark, Trade Name, or Service Mark). For complex situations such as a change in legal ownership, contact BREG directly at (808) 586-2727 or breg@dcca.hawaii.gov before filing.
Canceling your Hawaii trade name
- File a signed cancellation request letter. No separate BREG form is required, though BREG also provides specific cancellation forms for entities and for individuals or sole proprietors on the BREG forms page.
- Submit through any available channel — email, fax, mail, or in person. There is no filing fee to cancel.
Keep in mind: Canceling your BREG registration only removes the name from the state's public registry. It does not automatically close any business bank accounts, licenses, or contracts that reference the trade name.
Hawaii trade name tax considerations
Registering a trade name with BREG is a name filing, not a tax event. Your tax obligations, filing status, and existing EIN stay exactly as they were.
A trade name cannot have an EIN of its own. The underlying business or person may need one, but that requirement comes from the business structure, not the name registration.
One tax step that's easy to overlook: the Hawaii General Excise Tax (GET) license. A GET license is required for anyone doing business in Hawaii and functions as a general business license. You obtain it by filing Form BB-1, the State of Hawaii Basic Business Application, with the Hawaii Department of Taxation. The GET applies to most revenue your business earns, not just retail sales. For a full overview of what licenses your business may need, see how to get a Hawaii business license.
If you operate under more than one trade name, the Department of Taxation requires Form G-50, the General Excise Branch License Maintenance Form, to register a branch license for each trade name and location address. Branch licenses are free.
When applying for your GET license on Form BB-1, enter your trade name in the "Trade name or doing business as (DBA) name, if any" field. This connects your operating name to your tax account with the Department of Taxation.
Trade name registration and tax registration are parallel steps, not the same step. Form T-1 with BREG handles your name on the public record. Form BB-1 with the Department of Taxation handles your GET obligation. Filing one does not satisfy the other.
FAQs about DBAs in Hawaii
Does a Hawaii trade name registration protect my business name statewide?
Yes. A single DCCA/BREG filing covers all islands and counties. However, it does not grant exclusive trademark rights. Another business could use the same name in a different industry, and the registration alone would not resolve that dispute. For exclusive, enforceable protection, a federal trademark through the USPTO is the right next step.
What is the annual fee for an LLC in Hawaii?
The online filing fee for a Hawaii LLC annual report is $12.50, separate from the $50.00 trade name registration fee. Confirm the current fee at cca.hawaii.gov/breg/ before filing. You can learn more about the process in our guide on how to file a Hawaii annual report.
Can I use a Hawaii trade name on contracts and invoices?
Yes. Once registered, you can use your trade name on business documents, invoices, contracts, and marketing materials. Some contracts may still require disclosure of the legal owner behind the trade name. For contract-specific questions, speak with a Hawaii business formation attorney.
Do I need a separate trade name registration for each island or county in Hawaii?
No. A DCCA/BREG registration is statewide and covers the entire state.
How do I register a business name in Hawaii?
File Form T-1 with BREG and pay the $50.00 filing fee. You can submit online, by mail, by fax, or in person. Registration is valid for five years. See the How to register a trade name in Hawaii: Step-by-step section above for the complete walkthrough.
