How to Start an LLC in New Hampshire: Complete 2026 Guide

How to Form an LLC: Step-by-Step

1. 1

   Choose Your LLC Name

   Pick a unique name that ends with 'LLC' or 'Limited Liability Company' and isn't already taken in New Hampshire. Search the Secretary of State's business database to confirm availability before proceeding.

   Pro tip: Reserve your name for 120 days ($15 fee) if you need time to prepare other documents before filing.
2. 2

   Designate a Registered Agent

   Choose someone with a New Hampshire address to receive legal documents for your LLC. This can be yourself, a friend, or a professional service like ZenBusiness or Northwest Registered Agent.

   Pro tip: Using a professional registered agent keeps your home address private and ensures you never miss important legal notices.
3. 3

   File Certificate of Formation

   Submit Form LLC-1 to the New Hampshire Secretary of State with the $100 filing fee. You can file online, by mail, or in person at their Concord office.

   Pro tip: Online filing is fastest and provides immediate confirmation of your submission.
4. 4

   Create an Operating Agreement

   While not required by New Hampshire law, draft an operating agreement to outline ownership, management structure, and operating procedures. This protects your limited liability status and prevents disputes.

   Pro tip: Even single-member LLCs benefit from an operating agreement to maintain clear business separation from personal activities.
5. 5

   Obtain Your EIN

   Apply for an Employer Identification Number from the IRS online at irs.gov. This free federal tax ID number is required for banking, hiring employees, and filing taxes.

   Pro tip: Apply for your EIN immediately after your LLC is approved - the process is free and takes just minutes online.
6. 6

   Open a Business Bank Account

   Use your Certificate of Formation and EIN to open a dedicated business bank account. This keeps your business finances separate from personal accounts, which is crucial for maintaining limited liability protection.

   Pro tip: Compare business account fees and features across multiple banks - many offer free business checking for LLCs.
7. 7

   Get Required Licenses and Permits

   Determine what licenses your specific business needs at the federal, state, and local level. Check with New Hampshire's Business License Information Center and your city/town clerk for requirements.

   Pro tip: Start the licensing process early as some permits can take weeks to approve and may be required before you can legally operate.
