How to Reinstate a Business

To Reinstate a Business:
Montana (domestic) corporations and LLCs are eligible for reinstatement within 5 years of their dissolution date. Out-of-state (foreign) entity types are not eligible to reinstate and must requalify. Most domestic business registrations require a Title 15 Certificate from the MT Department of Revenue to be reinstated. Request the certificate through the Department of Revenue's Transaction Portal. (A certificate is not required for single-member LLCs not taxed as corporations.)
Once you have your Title 15 certificate, please follow the steps below. Note that you must file all missing annual reports AND a reinstatement application to return the registration to an active status.

File your annual reports

1. Visit the online filing portal at https://biz.sosmt.gov/
2. Sign in to the site with your username and password. (If you don’t have an account, click the login button and you’ll see where you can create one.)
3. Once signed in, search for the business registration using the “Search” in the left-side menu.
4. Click on the business name in the results list, and find a panel on the right side of the screen.
5. Click the “File Annual Report” button, follow the steps, and make the payment ($35) to file each missing annual report.

Complete the reinstatement

1. When the annual reports are completed for all previous years, click on the “Filing Actions” button and choose the “Reinstatement” form.
2. Complete the form and upload the tax certificate to the documents page, if required.
3. Submit the filing for processing with its required fee. (Profit Corp - $30, LLC - $35, Nonprofit Corp - $10)
4. The Secretary of State's office will review the filing; once approved, the registration will be active again. All filed documents and receipts can be obtained from the “Work Queue.”
