How to Amend a New Hampshire LLC or Corporation

Business changes happen. Your company may move, expand into a new line of work, change its name, or update ownership details. When that happens, your state records should reflect the new reality. In New Hampshire, LLCs and corporations use amendment filings to update formation documents and keep their business information accurate.

If you run a New Hampshire business, knowing when to amend your formation document can save time, reduce compliance risk, and help you avoid problems with banks, licensing agencies, and the state’s good standing process. This guide explains when an amendment is needed, what forms New Hampshire uses, and how to file the change correctly.

What an amendment does

An amendment updates the public record for your business entity. For an LLC, that usually means changing information in the Certificate of Formation. For a corporation, it means changing information in the Articles of Incorporation.

Typical reasons to amend include:

• Changing the business name
• Updating the company purpose or NAICS code
• Revising share structure for a corporation
• Making changes to internal governing provisions
• Correcting information that is no longer accurate in the formation record

An amendment is not the same thing as a tax filing, an annual report, or a simple internal record update. It is a formal state filing that changes the entity’s public records.

LLCs vs. corporations in New Hampshire

The filing name depends on your entity type:

• New Hampshire LLCs amend the Certificate of Formation using Form LLC-3, Certificate of Amendment.
• New Hampshire corporations amend the Articles of Incorporation using Form 14, Articles of Amendment.

Both filings are used to update the original formation document, but the details you provide will differ depending on whether you operate as an LLC or a corporation.

When you should file an amendment

You should file an amendment when the information in your formation document changes and the state requires a formal update.

For example, a New Hampshire business should consider an amendment if it needs to:

• Rename the entity
• Change the stated business purpose
• Update the NAICS code used in the state’s records
• Change a corporation’s share provisions
• Revise other provisions that were part of the original formation filing

The New Hampshire Secretary of State also notes that if a business changes its primary purpose or NAICS code, an amendment filing and fee are required.

When a different filing may be required

Not every business change is handled through a standard amendment. Some updates use a separate form or a different state process.

A common example is a change to the registered agent or registered office. In New Hampshire, that is handled through Form 10, Statement of Change of Registered Office or Registered Agent or Both.

According to the state’s current guidance, this filing carries a $15 fee.

Other changes may also have separate update procedures depending on the entity type and what information is changing. Before filing, confirm whether the change belongs on an amendment, an annual report update, or another state form.

Information to gather before filing

The filing goes more smoothly if you prepare the details in advance.

For an LLC or corporation amendment, gather:

• Your exact legal business name
• Your New Hampshire business ID, if needed
• The exact language of the amendment you want to make
• Any approved change to share structure or class rights, if applicable
• The date the change was approved
• The name and signature of an authorized person

If multiple changes are being made at once, write them clearly and make sure the wording matches the internal approval you received.

How to amend a New Hampshire LLC

If you own a New Hampshire LLC, the amendment process usually follows these steps.

1. Confirm that an amendment is the correct filing

Review the Certificate of Formation and identify exactly what is changing. If the change affects the public formation record, an amendment may be the right filing.

2. Draft the amendment text

Write the new language carefully. If the amendment changes the entity name or purpose, the new wording should be precise and consistent with your business decision.

3. File Form LLC-3

File Form LLC-3, Certificate of Amendment, through NH QuickStart or by mail.

The state’s filing fee for this amendment form is $35 at the time of writing.

4. Keep the confirmation with your records

After the state processes the filing, keep the confirmation with your company records. You may need it for banks, licensing, lenders, or future compliance tasks.

How to amend a New Hampshire corporation

For a corporation, the process is similar, but the filing document is different.

1. Identify the section that needs to change

Corporations often amend their Articles of Incorporation when changing the business name, purpose, or share-related provisions.

2. Prepare the Articles of Amendment

The amendment should clearly describe what is being changed. If your filing involves share classes, share rights, or authorization changes, the wording should be carefully drafted to match the board and shareholder approval.

3. File Form 14

New Hampshire corporations use Form 14, Articles of Amendment to the Articles of Incorporation.

The current filing fee is $35.

Corporations may file online, by mail, or in person, depending on the filing option available through the Secretary of State.

4. Retain proof of filing

Save the stamped or approved filing for your corporate records. This document becomes part of the company’s official history and may be needed later for due diligence or compliance review.

Can you restate the formation document instead?

Yes. New Hampshire also allows businesses to use a restated formation document with or without amendments.

A restated filing is useful when the original document has been amended multiple times and you want a cleaner, consolidated version of the record. Instead of layering new amendments on top of old language, a restated document can present the current terms in one place.

This does not change the legal entity itself. It simply replaces the record document with a more readable version that includes the updated provisions.

Why staying current matters

Keeping your state records up to date is more than administrative housekeeping. Inaccurate records can create real business problems.

If your entity information is outdated, you may run into issues with:

• Business banking
• Loan applications
• Licensing and permit renewals
• Foreign qualification in other states
• Vendor verification
• Certificates of good standing

The New Hampshire Secretary of State uses public business records to track entity status and filings. If the record is incorrect, it can complicate compliance and make it harder to prove your business is in good standing.

Common mistakes to avoid

A few filing errors come up often:

• Filing an amendment when a separate form is required
• Using vague amendment language instead of exact wording
• Forgetting internal approval before submitting the filing
• Leaving out a signature from an authorized person
• Not keeping a copy of the filed amendment for company records

The biggest mistake is assuming that all business changes can be handled the same way. New Hampshire uses different forms for different types of updates, so it is worth confirming the filing path before you submit anything.

Final thoughts

A New Hampshire business amendment is straightforward when you know which form to use and which changes belong in a separate filing. LLCs use Form LLC-3, corporations use Form 14, and registered agent or registered office changes use Form 10.

If your company has outgrown the information in its original formation document, updating the state record is the right next step. Accurate records support good standing, reduce friction with third parties, and keep your business ready for what comes next.

Whether you are updating a New Hampshire LLC or corporation, taking care of the filing promptly is usually the best way to protect the business and keep compliance on track.
