Fraud warning: deceptive third-party solicitations
The Montana Secretary of State's office continues to warn business owners about third-party mailers and emails — with names like "National Business Services" and "US Filing Services" — that mimic official state notices and demand payment (recent examples cite a $51 fee) to file an annual report or obtain a certificate. These solicitations are not affiliated with the Secretary of State. Annual reports and certificates should only be filed and paid for directly through biz.sosmt.gov.
