How to Change Your LLC Name in Connecticut

Changing your LLC name in Connecticut is a straightforward process that involves filing Articles of Amendment with the Connecticut Secretary of State. Whether you’re rebranding your business, expanding into new markets, or simply want a name that better reflects your company’s mission, you can complete this change for $120 and typically see approval within 5-7 business days.

When You Might Need to Change Your LLC Name

Business owners change their LLC names for several practical reasons. Your original name might be too limiting as your business grows and diversifies. You may discover another company is using a similar name, creating potential trademark conflicts. Sometimes the name just doesn’t resonate with customers or reflect your brand anymore.

Other common reasons include:

• Merging with another business or acquiring a new company
• Expanding into markets where your current name doesn’t translate well
• Simplifying a complex or hard-to-pronounce business name
• Avoiding negative associations with your current name
• Aligning with a new business strategy or target market

Step-by-Step Process to Change Your Connecticut LLC Name

Step 1: Choose and Verify Your New Name

Before filing any paperwork, you need to ensure your desired name is available and complies with Connecticut naming requirements. Your new LLC name must include “Limited Liability Company,” “LLC,” or “L.L.C.” and be distinguishable from existing business names in the state.

Check name availability through the Connecticut LLC name search system. This search covers all registered business entities in Connecticut, including corporations, LLCs, and partnerships.

Step 2: Consider Reserving Your New Name

If you’re not ready to file immediately but want to secure your chosen name, you can reserve it for $60 using an Application for Reservation of Name. This gives you 120 days to file your Articles of Amendment while ensuring no one else can register your desired name.

Step 3: File Articles of Amendment

Connecticut requires you to file Articles of Amendment to officially change your LLC name. You can file online or by paper with the Connecticut Secretary of State.

The Articles of Amendment must include:

• Your LLC’s current legal name
• The new name you want to adopt
• A statement that the amendment has been approved according to your operating agreement
• The signature of a manager (if manager-managed) or member (if member-managed)

The filing fee is $120 whether you file online or by mail. Online filing typically processes faster and allows you to track your submission status.

Step 4: Wait for Approval

Standard processing time is 5-7 business days for online filings. Paper filings may take longer. Connecticut offers expedited processing for online filings only, though the specific expedited fee isn’t disclosed publicly. Contact the Secretary of State directly for expedited service pricing and availability.

Essential Updates After Your Name Change is Approved

Once Connecticut approves your LLC name change, you’ll need to update your information with multiple agencies and organizations to ensure your business operates smoothly under its new name.

Update Your EIN with the IRS

The IRS requires notification when you change your business name, even though your EIN remains the same. Call the IRS Business & Specialty Tax Line at (800) 829-4933 or write to them with your name change documentation. They’ll send you Letter 147C confirming the update.

Update Financial Accounts

Contact your bank and any other financial institutions where you have business accounts. They’ll typically require a copy of your approved Articles of Amendment to update their records. This includes:

• Business checking and savings accounts
• Business credit cards and lines of credit
• Merchant services and payment processing accounts
• Investment accounts

Update Licenses and Permits

Review all your business licenses and permits to determine which ones need updating. This might include:

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

Some agencies may charge fees for updating licenses, while others provide the service at no cost.

Update Your Operating Agreement

Amend your LLC’s operating agreement to reflect the new business name. While Connecticut doesn’t require you to file your operating agreement with the state, keeping it current protects your limited liability status and ensures all members are aware of the change.

Update Marketing Materials and Online Presence

Don’t forget to update your business’s public-facing materials:

• Website domain and content
• Business cards and letterhead
• Social media accounts
• Directory listings and review sites
• Marketing materials and advertisements
• Email signatures

Processing Time and Expedited Options

Standard processing for Connecticut LLC name changes is 5-7 business days for online filings. Paper filings typically take longer due to manual processing requirements.

Connecticut offers expedited processing exclusively for online submissions. The state doesn’t publish specific expedited fees, so contact the Secretary of State directly if you need faster processing.

Plan ahead when possible, especially if your name change needs to coordinate with marketing campaigns, lease agreements, or other business activities.

Frequently Asked Questions

Can I change my LLC name to anything I want?

Your new name must comply with Connecticut naming requirements. It must include an LLC designation (“Limited Liability Company,” “LLC,” or “L.L.C.”) and be distinguishable from existing registered business names in the state. The name cannot suggest the LLC is organized for purposes other than those permitted by Connecticut law.

Do I need to notify customers about the name change?

While Connecticut doesn’t legally require customer notification, it’s good business practice to inform customers, vendors, and partners about your name change. This prevents confusion and maintains business relationships during the transition.

Will changing my name affect my credit history?

Your business credit history should remain intact since your EIN doesn’t change. However, you’ll need to update your information with credit reporting agencies and any creditors to ensure continuity in your credit profile.

How long do I have to update everything after the name change?

While there’s no specific deadline for updating all your records, you should complete updates as quickly as possible to avoid business disruptions. Start with the IRS and your bank, then work through licenses, permits, and marketing materials systematically.

Can I operate under both names during the transition?

You can use a “doing business as” (DBA) name during the transition period if needed, but you’ll need to register the DBA with the appropriate county clerk where your business operates. This allows you to conduct business under your old name while transitioning to the new one.
