I know with BSA the annual audit has a 15 month window but is there any stipulation for wire transfer audit? We do it annually but for example last year we did it in July and this year it's scheduled for November.

There is no stipulated 15-month window on a BSA audit. Frequency of audits are derived from your risk assessments (except the annual ACH audit which has a November deadline).

Our firm recommends a Wire Transfer audit once per calendar year due to the inherent risk in the function. Obviously, it wouldn't make sense to do one in November of year 1 and then in February of year 2. I don't have a problem with your scheduling.
