When you change your business name, you need to notify the Montana Secretary of State by filing an amendment to update your official business records.
You can file an amendment to your business name on the Montana Secretary of State’s online filing portal at https://biz.sosmt.gov/.
Here are the steps:
Sign in to the portal with your username and password (create an account if you don’t have one).
Use the search function to find your existing business registration.
Click on your business name from the results list.
On the right-hand panel, click the "Filing Actions" button.
Select the amendment form (such as Articles of Correction or Name Change).
Complete the online amendment form with the correct business name and any other requested information.
Submit your amendment and pay the applicable fee online.
Once your filing is approved, you will receive a confirmation email with instructions on downloading your updated filings.
If you have any questions, you can contact the Montana Secretary of State's Business Services at (406) 444-3665 for assistance.
Additionally, you must inform the Internal Revenue Service (IRS) of the name change. You should also notify any Montana state agencies where you have an account or license. Don’t forget to update your local bank and your city or county officials about the name change to ensure all your records remain accurate and current.
