We operate branches in the states of New Mexico and Iowa. Those states request that sales tax is remitted to the state for transaction fees. We are unsure if the Reg E disclosure needs to have the sales tax amount calculated out for the customer and disclosed on the disclosure or can we just generically say "New Mexico only: All fees subject to New Mexico gross receipt tax" and for IA "All fees subject to Iowa sales tax".
Example: Our Foreign ATM Transaction Fee is $2. Do we have to put a total fee of $2.14 for NM and IA on our Reg E disclosure? Or can we just generically say that in those states the customer is subject to a sales tax?

Thank you for any input!
