In Texas, if you notify a hotel upon check-in that you will occupy the room for at least 30 consecutive days, the state occupancy taxes will be waived after the 30th day, retroactive to the first day; the total amount will be credited to your bill. (Any interruption in the term of occupancy will void the exemption.)
If you stay in the hotel for more than 30 consecutive days without notifying the hotel of your intention, occupancy taxes will be waived for the 31st day and all consecutive days, but will not be waived retroactively.
If you learn after check-in that you will be staying for 30+ consecutive days, notify the hotel immediately; after the 30th day, occupancy taxes will be waived retroactively to the date of notification.
