Follow our How to Set up an LLC in New Hampshire guide below to get started.

Steps to form an L L C in New Hampshire

Step 1: Create A Name For Your New Hampshire LLC

Before you register your LLC, you'll need to come up with a name. Your business name needs to be catchy for branding purposes and legitimate for legal purposes.

We go into depth on this topic in our LLC naming guide. We’ll go over the basics below.

Naming Your LLC

First, brainstorm some possibilities. Use our LLC name generator to get the ideas flowing.

Next, make sure your name meets New Hampshire guidelines:

  • it contains the words limited liability company, limited company, LLC, or L.L.C.
  • it doesn't contain restricted words or phrases (these often include words like bank, attorney, and university) without approval
  • it's distinguishable from any other entity or trade name registered in New Hampshire
  • full list of New Hampshire naming guidelines

Next, do a New Hampshire LLC name search with the Department of State to find out if your name is available in New Hampshire.

If your business name is available and meets guidelines, you’ll be able to register it when you file your Certificate of Formation with the Department of State.

Is the URL available? Before you commit 100% to a name, check to see if there’s a good web domain available.

We recommend buying your domain right away because even if launching a business website isn’t on your radar right now, it will be soon.

Step 2: Appoint A Registered Agent

When you file your Certificate of Formation, you'll need to list a registered agent.

A registered agent's job is to accept legal documents like service of process and tax notices for your LLC.

Your registered agent can be a person or a registered agent service. You can act as your own registered agent, but many business owners choose to use a registered agent service.

Here are a few things to think about before you decide to act as your own registered agent:

  • You’ll need to be available during normal (9 am - 5 pm) business hours at the address you provide
  • If you run your business from home, you’ll have to make your personal address public
  • You could be served with a lawsuit in front of your family or coworkers

Recommended: Most registered agent services offer a year of registered agent service free when you form an LLC with them. 

Step 3: File the NH Certificate of Formation

It’s time to officially form your LLC by filing your Certificate of Formation with the Nebraska Department of State .

You can file online with the Department of State or fill out a hard copy of the NH Certificate of Formation and mail it in. The filing fee is $100. 

Recommended: Now is a good time to decide if your LLC will be member-managed vs manager-managed.

You'll need to know the following information to complete the form

  1. Entity Name and Address
  2. Business Purpose
  3. Registered Agent Name and Registered Office Address
  4. Governing Authority Type (LLC Management Structure)

For more detailed help with completing the form, visit our New Hampshire Certificate of Formation guide.

Mail Your Certificate of Formation:

Send the form and payment (payable to the Department of State) to:

Corporation Division, NH Dept. of State
107 N Main St, Rm 204
Concord, NH 03301

How long does it take to get an LLC approved? LLC processing time is 7 to 10 business days by mail.

Step 4: Create A New Hampshire LLC Operating Agreement

Creating a New Hampshire LLC operating agreement is the only way to legally lock down your LLC’s management and ownership structure. Having this document in place will give you something to return to if a dispute or lawsuit arises. 

Even single-member LLCs benefit from having an operating agreement.

Your operating agreement should outline the following:

  • Each member’s responsibilities
  • How new members will be admitted
  • How existing members may transfer or terminate their membership
  • How profits and dividends will be distributed

You can add as many provisions as you want, as long as they don't conflict with New Hampshire business law. Take a look at our What is an Operating Agreement guide to learn more.

Step 5: Obtain An EIN

An Employer Identification Number (EIN) is like a Social Security number (SSN) for your company. The IRS and the state of New Hampshire will use this number to track your business activity.

Your EIN will come in handy when it’s time to:

  • Open a business bank account
  • File Federal and State taxes
  • Hire employees

The best way to get an EIN for your LLC in New Hampshire is by using the free online application on the IRS website.
