How to Change Your LLC Name in South Dakota

Changing your South Dakota LLC name requires filing Articles of Amendment with the Secretary of State and paying the required fee. Whether you need to rebrand, resolve trademark issues, or simply want a better business name, the process is straightforward but involves several important steps both before and after filing.

When You Might Need to Change Your LLC Name

Several situations could prompt you to change your South Dakota LLC name:

• Business pivot or rebranding: Your company has evolved and needs a name that better reflects your current services or market position
• Trademark conflicts: Another business claims your current name infringes on their trademark rights
• Market expansion: You’re entering new markets where your current name doesn’t resonate or has negative connotations
• Partnership changes: Adding or removing partners may necessitate a name change to reflect new ownership structure
• Better domain availability: You’ve found a more marketable name with available web domains and social media handles

Step-by-Step Process to Change Your LLC Name

Step 1: Check Name Availability

Before filing any paperwork, you must verify that your desired new name is available and complies with South Dakota naming requirements. The name must be distinguishable from other business entities registered in the state and include “Limited Liability Company” or an approved abbreviation like “LLC” or “L.L.C.”

You can search available LLC names using the South Dakota Secretary of State’s online database. If you find your desired name is available, consider reserving it for $25 to hold it for 120 days while you prepare your amendment documents.

Step 2: Prepare Articles of Amendment

You’ll need to file Articles of Amendment to officially change your LLC name. This document must include:

• Your LLC’s current legal name
• The proposed new name
• A statement that the amendment was approved according to your operating agreement and state law
• The signature of an authorized member or manager

The Articles of Amendment form is available on the South Dakota Secretary of State website.

Step 3: File and Pay the Required Fee

Submit your completed Articles of Amendment along with the filing fee. You have two options:

• Online filing: $153 total ($150 base fee + $3 convenience fee)
• Paper filing: $165 total ($150 base fee + $15 paper processing fee)

For faster processing, you can add expedited service for an additional $50. The state accepts major credit and debit cards for payment.

After Your Name Change is Approved

Once the Secretary of State processes your Articles of Amendment, you’ll receive confirmation that your LLC name change is official. However, your work isn’t done. You must update your business information with various agencies and organizations.

Update Your Federal Tax Information

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

• Calling the IRS Business and Specialty Tax Line at 800-829-4933
• Faxing a signed letter explaining the name change to 855-641-6935
• Mailing the letter to the IRS at the address provided in Publication 1635

The IRS will send you Letter 147C confirming your name change, which you should keep for your records.

Update Banking and Financial Accounts

Contact your business bank to update your account names and any associated business credit cards or loans. Most banks will require:

• A certified copy of your filed Articles of Amendment
• Updated signature cards
• New business checks and debit cards

Update Business Licenses and Permits

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

• State business licenses
• Professional licenses
• Sales tax permits
• Industry-specific permits
• Local business licenses

Some licenses may require you to file amendments, while others might need complete renewal under the new name.

Update Your Operating Agreement

Amend your LLC’s operating agreement to reflect the new business name. Even though South Dakota doesn’t require an operating agreement, having one protects your business interests and clarifies member roles and responsibilities.

Update Marketing Materials and Online Presence

Update all your business marketing materials, including:

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

Timeline and Processing

The South Dakota Secretary of State processes Articles of Amendment during the normal course of business. Standard processing typically takes several business days to a few weeks, depending on filing volume.

If you need faster processing, the expedited service option for an additional $50 can significantly reduce processing time. Online filings generally process faster than paper submissions.
