Renaissance Aruba does not deduct any taxes regardless of the win amount.
If a guest is looking to file win/losses for taxes then the casino staff can print that out. There is also an app guest can download and their play information would display on that as well.
If a guest wins over the international customs threshold ($10k), the property would print out a statement (winning statement) for the guest on property so they can declare it at the airport. This form is required to carry that much cash.
