Tip - File and pay your sales tax returns by the 15th of the month to qualify for vendor compensation credit. When scheduling your WYIFS payment, please remember that while you can schedule it for the last day of the month, it must be scheduled for the 15th day of the month for you to qualify for vendor’s compensation if all other aspects of your account are in good standing.
