How to Change Your LLC Name in New Hampshire

Changing your LLC’s name in New Hampshire requires filing Articles of Amendment with the Secretary of State and paying a $100 filing fee. The process involves several steps, from checking name availability to updating all your business records after approval.

Whether you’re rebranding for marketing reasons, avoiding trademark conflicts, or simply want a name that better reflects your business, here’s everything you need to know about changing your New Hampshire LLC name.

When You Might Need to Change Your LLC Name

Business owners change their LLC names for various reasons:

• Rebranding: Your business has evolved, and the current name no longer fits your services or target market
• Trademark issues: Another business claims rights to a similar name, or you want to avoid potential conflicts
• Expansion: You’re adding new services or entering new markets that your current name doesn’t reflect
• Partnership changes: Adding or removing partners whose names are part of the LLC name
• Marketing reasons: A more memorable, marketable, or professional-sounding name

Step-by-Step Process to Change Your LLC Name

Step 1: Check New Name Availability

Before filing any paperwork, you must verify that your desired new name is available for use in New Hampshire. The name must be distinguishable from all other business entities registered with the Secretary of State.

Your new LLC name must also comply with New Hampshire’s naming requirements:

• Include “Limited Liability Company,” “LLC,” or “L.L.C.”
• Not contain prohibited words without proper licensing
• Be distinguishable from existing registered business names

You can search for name availability using the New Hampshire LLC name search tool on the Secretary of State website. If your preferred name is available, consider reserving it for $15 to hold it while you prepare your amendment filing.

Step 2: Prepare Articles of Amendment

New Hampshire requires you to file Articles of Amendment to officially change your LLC name. You’ll need to provide:

• Current LLC name exactly as it appears on your Certificate of Formation
• New desired LLC name
• Statement that the amendment was approved according to your operating agreement
• Signature of an authorized member or manager

The Articles of Amendment form is available on the New Hampshire Secretary of State website. Make sure all information is accurate before submitting, as errors can delay processing.

Step 3: File and Pay the Fee

Submit your completed Articles of Amendment along with the $100 filing fee. You can file either:

• Online: Adds a $2 processing fee for a total of $102
• By mail: Send to New Hampshire Secretary of State, State House Room 204, Concord, NH 03301

Processing typically takes within 30 days for standard filing. Online submissions may receive faster approval than paper filings.

After Your Name Change is Approved

Once the Secretary of State approves your Articles of Amendment, your LLC’s legal name is officially changed. However, your work isn’t done. You need to update all records and accounts that reference your old name.

Update Your Federal Tax Records

Contact the IRS to update your Employer Identification Number (EIN) records with your new LLC name. You can:

• Call the IRS Business and Specialty Tax Line at 800-829-4933
• Send a letter to the IRS with your EIN, old name, new name, and effective date
• Wait for Letter 147C from the IRS confirming the name change

Your EIN number stays the same, but the IRS needs to update their records to match your new legal name.

Update Banking and Financial Accounts

Contact all banks and financial institutions where your LLC has accounts. Most banks require:

• Copy of the approved Articles of Amendment
• Updated operating agreement (if member names changed)
• New signature cards
• Updated business banking resolutions

This process can take several business days, so plan accordingly if you have pending transactions or automatic payments.

Update Business Licenses and Permits

Review all business licenses, permits, and professional certifications your LLC holds. Contact each issuing agency to update their records with your new name. This might include:

• Professional licenses
• Sales tax permits
• Federal and state employer tax accounts
• Industry-specific permits
• Local business licenses

Update Your Operating Agreement

Amend your LLC’s operating agreement to reflect the new name. Even if New Hampshire doesn’t require an operating agreement, having updated internal documents prevents confusion and maintains good corporate records.

Update Marketing Materials and Online Presence

Update all customer-facing materials with your new name:

• Website domain and content
• Business cards and letterhead
• Social media profiles
• Email signatures
• Advertising materials
• Contracts and proposals

Consider creating a communication plan to inform customers, vendors, and partners about your name change.

Processing Time and Costs

The total cost to change your LLC name in New Hampshire includes:

• Articles of Amendment: $100 (paper filing) or $102 (online filing)
• Name reservation (optional): $15
• Additional costs: New business cards, signage, website updates, etc.

Processing typically takes within 30 days from the Secretary of State’s receipt of your filing. Online filings may be processed faster than paper submissions.

Plan for additional time to update all your business records after the name change is approved. The complete process of updating all accounts and materials can take several weeks.

Alternatives to Consider

DBA (Doing Business As) Name

If you want to operate under a different name without changing your legal LLC name, consider filing a DBA. New Hampshire calls this a “Trade Name” and charges a $50 filing fee. This option works well for:

• Testing a new brand before committing to a full name change
• Operating multiple brands under one LLC
• Using a shorter, more marketable name for customer-facing activities

Forming a New LLC

In some cases, it might make more sense to start a new LLC with your desired name and wind down the old one. Consider this option if:

• You want to completely rebrand and start fresh
• There are liability concerns with the existing entity
• The business structure or ownership is changing significantly

Frequently Asked Questions

Can I change my LLC name online?

Yes, New Hampshire allows online filing of Articles of Amendment through their Secretary of State website. Online filing costs $102 ($100 filing fee plus $2 processing fee) and may be processed faster than paper filings.

How long does a name change take?

The Secretary of State processes Articles of Amendment within 30 days. However, updating all your business records, bank accounts, and licenses can take several additional weeks.

What if my desired name isn’t available?

If your preferred name is taken, try variations like adding descriptive words or using different LLC designators. You can also contact the Secretary of State to see if similar names are distinguishable enough to be approved.

Do I need to notify customers about the name change?

While not legally required, it’s good business practice to inform customers, vendors, and partners about your name change. This helps maintain relationships and ensures you don’t lose business due to confusion.

Can I change my registered agent at the same time?

Yes, but this requires a separate filing. If you need to update your New Hampshire registered agent, you can file those changes separately or simultaneously with your name change.

Changing your LLC name in New Hampshire is straightforward but requires attention to detail and follow-through. By carefully following these steps and updating all your business records, you can successfully rebrand your LLC while maintaining compliance and protecting your business relationships.
