As noted, you need to familiarize yourself with your state's record retention requirements. They could say anything.
As for BSA, you are not required to keep "the form." You are required to keep the information listed in the regulation for 5 years. How you keep it is how you keep it; i.e. microfilm, fiche, electronic, paper, they really don't care as long as you can produce it in a reasonable period of time.
