The Tax Exempt Report displays bookings that have been set to "Tax Exempt" in the Booking Data of the booking. See Booking Data

This is a manual setting that prevents tax(s) from being automatically added to the folio when Room Rent, or other Items, are charged to the folio (such as manually or via Night Audit processes).

The booking must be set to "Tax Exempt" before night audit in order to prevent the tax from being automatically added to the folio. Again, if these Tax Exempt settings are checked, then ONLY Room Rent will be charged to the folio and NOT any taxes associated to the Room Rent item.

The report displays guest and booking information, folio balance and payments, the tax amount that would have been charged and the total room rent of the booking without tax. Reports can be run for one year at a time, starting on any date you choose (past or future), but will be limited to one year.

Note that this report is based on creation date of the booking, not the Arrival and Departure dates.
