How to Register a Business Name in New Hampshire

If you plan to open a business in New Hampshire you must find out whether or not you need to register your business name. If you are going to be self-employed and use only your legal name for your business, then you do not need to register your business name in New Hampshire. If you are going to use any name besides your own personal legal name you need to register your business name with New Hampshire. It is easy to do and will only take a few minutes.

Lookup your business name. The secretary of state (where you will need to register your business name in New Hampshire) has a relatively helpful Web site (see Resources below). Once there, you can, and should, look up your business name to make sure you don't register a business name that is the same or similar to others in the state. Your business name must be available to take the next steps.

Choose the proper business type. You will have to choose from the categories of corporation, limited liability company, limited liability partnership, non-profit, and trade name before continuing to the form. If you do not already know what type of business yours will be you need to go to a page on the Web site (see Resources below) to learn more about the different types of businesses and which one would be best for you.

Select the right form. Once you click on the right business type you can click on a link that will bring you to a page that will ask you if you want a foreign or domestic form. Since you are registering your business name in New Hampshire you will need to select "Domestic form."

Fill out the form online by selecting the appropriate answers in the PDF file, and then print out the form. Print out at least two copies, so you can keep one for your own records. Sign and date both forms.

Mail the form with your payment. The fee for your business name registration will be listed at the top of the form. You can send a check with your form. Make the check payable to the State of New Hampshire and mail to the address listed at the bottom of the form.


  • Take advantage of what you can get done online, which is everything except signing and mailing the form.
