Tourist (TDT) tax question

[Stefhan Malherbe]

Hello BP community,

I pay the TDT tax to the county each month for my monthly STR income.

However, I have a 50-day booking which covers most of February and March. Since this is a booking of more than 30 days, do I still need to pay the TDT tax? 

My understanding is that I must pay the TDT tax for any booking under 30 days but bookings over 30 days are considered long / medium term rental. 

The booking does not cover 30 days in a single month, it covers most of Feb and March but not 30 days in each specific month. I also do not have a separate lease agreement for this booking, only the Airbnb booking confirmation. 

 I appreciate any advice.

Thank you
