I will add that BSA is just one concern when you bank a finance company. You may also have compliance and UDAAP concerns if the finance company is using your bank to obtain payments from consumers so at the very least, you need to know if your state requires finance lenders to be licensed, and if so, that your customer has the appropriate license and it is current. If your customer asks for ACH origination services, then you will really need to take a look at their operations in terms of UDAAP, SCRA, Military Lending Act, Fair Dept Collection and so on. Request copies of independent audits.
If the finance lender does mortgage lending, then they are required to have a BSA/AML program and you can request copies of independent testing of that program.
