Money Services Business (MSB) List

The MSB Registration List contains entities that have registered as Money Services Businesses (MSBs) pursuant to the Bank Secrecy Act (BSA) regulations at 31 CFR 1022.380(a)-(f), administered by the Financial Crimes Enforcement Network (FinCEN). Once a year, FinCEN drops from the updated List any entities that have not renewed their MSB registrations by the renewal deadline. The IRS contacts those businesses that appear to have failed to renew their registrations, usually by the end of August, to determine if this was an inadvertent error or if the businesses no longer conduct MSB services that would require them to register.
