Dear Sir 

I have booked an under construction flats costing more than Rs 50 lacs.

It includes Rs BSP + PARKING charges + PLC+ Int.free Security Deposit + lease rent + external & internal dev charges etc

Pl guide me as to whether 

- 1% TDS  is to be deducted on BSP ONLY  or total cost including all other charges as detailed above?
