Indiana Form MCS-NC is a specialized affidavit used by the Motor Carrier Services Division to officially document a change in a business’s legal name when the underlying business structure remains exactly the same. This form is intended for companies that have legally renamed themselves—such as amending their articles of incorporation—but have not dissolved, re-incorporated, or changed their Federal Employer Identification Number (FEIN). It serves as a sworn statement to link the old identity to the new one in the state’s records, ensuring that tax reporting and operating authority remain consistent. It is critical to understand that this form is not for use if your business has undergone a structural change, such as a sole proprietorship converting into a partnership (which often happens when a spouse joins a business), or if you have been assigned a new FEIN; in those cases, the state considers it a new entity entirely and requires you to open a new account rather than simply changing the name.
How To File Indiana Form MCS-NC
Filing this form requires you to physically complete the document, sign it, and mail it to the Indiana Department of Revenue. Because it is an affidavit containing a sworn statement, it must be signed by an individual with the authority to execute documents on behalf of the company, such as an owner, partner, or corporate officer. Once verified and signed, the original form should be mailed directly to the Motor Carrier Services Division at 7811 Milhouse Road, Suite M, Indianapolis, IN 46241-9612.

How To Complete Indiana Form MCS-NC (Line-By-Line Instructions)
Follow these specific instructions for each line to ensure your affidavit is accepted without delay.
Federal Employer Identification Number (FEIN)
Enter the nine-digit federal tax ID number assigned to your business. If this number has changed as part of your rebranding or restructuring, do not use this form; you must contact the department to set up a new entity instead.
Social Security Number (SSN)
This field is reserved exclusively for sole proprietors who do not operate with a FEIN. If you are a partnership, corporation, or a sole proprietor with a FEIN, leave this line blank.
Company’s Previous Legal Name
Write the full legal name of your business exactly as it appeared on your account before the change occurred.
Company’s New Legal Name
Enter the new full legal name of the business exactly as it is legally organized and recognized for federal tax purposes.
Name Under Which You Are Doing Business As (DBA)
If your company uses a trade name or “DBA” that is different from the legal name you just entered, list that trade name here. If you do not use a separate trade name, you may leave this blank.
New DBA Name
If you are updating your trade name or adopting a new “DBA” alongside your legal name change, enter the new trade name in this space.
