What is a Trade Name good for?

A Trade Name is required for many businesses to legally operate and provides information on the people operating a business.  In addition to the legal requirement, a Trade Name offers other benefits such as proving the existence of a business, opening a bank account under a business name, registering a merchant account to accept credit cards, and others.

Who needs to register for a Hawaii Trade Name?

Sole proprietorships and general partnerships are the most common type of entities to register for a DBA, but again, this registration is optional. 

The legal name of a sole proprietor or partnership can be the owner’s full first and last name, but most will use a business name.

  • Proves the 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.

Trade Names can’t be registered using words that are related to a financial institution (such as financial services, banker, credit union, etc.), insurance, or Certified Public Accountant (CPA) unless the business is licensed to provide those services.

A Trade Name can’t use a business entity suffix that is different from the type of entity. For example, a sole proprietorship can’t use the words LLC or corporation in its name.

An EIN or Employer Identification Number (also informally called a business tax ID number) is a unique nine-digit number that some businesses will register for through the Internal Revenue Department (IRS). An EIN is required for certain types of business structures, such as partnerships, corporations, multi-member LLCs, or any business that has employees.

Sole proprietorships and single-member LLCs without employees can use the owner’s social security number to identify the business.
