Does anyone know where I can find a record retention schedule for banks doing business in New York State?

What do you mean by: Doing business in New York State? Are you a multi-State operation? If so, you should have your legal counsel review this opinion.

If not, then this is the citation in that opinion:

Very few States have detailed retention requirements. You might try contacting one of the NY State banking associations to see if they publish a more detailed retention guide. Such as: https://www.nyba.com/

Don't forget to cross-reference with federal regulations. You will need to comply with whichever is longer.

Thank you!
