How to File a New Hampshire LLC Amendment: A Step-by-Step Guide

As your business grows and evolves, the information you originally provided in your Certificate of Formation may need to change. In New Hampshire, when you need to update fundamental details like your LLC's name or its business purpose, you must formally file an amendment with the Department of State (DOS).

This guide provides a comprehensive, step-by-step walkthrough of the New Hampshire LLC amendment process, ensuring your business remains compliant and up to date.

When Do You Need an LLC Amendment?

A Certificate of Amendment is required whenever you make significant changes to your business structure as filed with the state. The most common reasons include:
* Changing the legal name of your LLC.
* Updating the business purpose of the LLC.
* Correcting information previously filed in the Certificate of Formation.

Step 1: Prepare the Certificate of Amendment

To begin the process, you must obtain and complete the "Limited Liability Company Certificate of Amendment to the Certificate of Formation."

  • Accuracy is Key: Ensure that all information, including your LLC’s current name as registered with the state, is accurate.
  • Form Preparation: You can type directly into the DOS-provided form or write clearly by hand in black ink.

Step 2: File with the New Hampshire Department of State

New Hampshire offers multiple ways to submit your amendment:

Online Filing

The quickest and most efficient way to file is through the New Hampshire Secretary of State’s website. Online filings allow for credit card payments and generally have the fastest processing times.

Filing by Mail or In Person

If you prefer a paper filing, you can mail the signed original amendment or drop it off in person at the DOS office in Concord.

  • Mailing Address:
    New Hampshire Department of State
    Corporate Division
    107 North Main Street
    Concord, NH 03301-4989

  • Filing Fees: The cost to file an LLC amendment in New Hampshire is $35. Checks should be made payable to the “State of New Hampshire.” If filing in person, cash must be in the exact amount owed.

Processing Times

Once submitted, the processing time varies depending on the method of filing:
* Mailed Documents: 5-8 business days.
* In-Person (Walked-in): 3-5 business days.
* Online: Usually the fastest method, often processed within a few business days.

After the amendment is processed, the DOS will mail an acknowledgment to the individual or LLC that filed the document.

What You Cannot Include in an Amendment

It is important to understand that not all business changes are handled via a Certificate of Amendment. In New Hampshire, you cannot use an amendment to:

1. Change Your Registered Agent

To change your registered office or registered agent, you must file a specific "Statement of Change of Registered Office or Registered Agent" form.

2. Update Principal or Mailing Addresses

If you have already filed your annual report, address updates must be submitted in writing on company letterhead via mail or email to the DOS.

3. Change Members or Managers

Updates to your LLC’s members or managers are not handled through an amendment. Instead, these changes must be submitted in writing on company letterhead to the DOS annual reports division.

Alternatives: Restated Certificate of Formation

If you have made numerous changes over time, you might consider filing a "Restated Certificate of Formation." This document compiles your original certificate and all subsequent amendments into a single, clean document. You can also file a "Restated Certificate of Formation including Amendment" if you wish to restate and make a new change simultaneously. The fee for either restatement form is also $35.
