TEC or Tax Exepmtion Certificates are required from time to time for appropriate TDS in a property sale. The TEC is an essential requirement for a property sale in general conditions for a NRI. The TEC helps in off-setting the non-essential excess TDS that may be appropriated by the Purchaser which is directed as per law. However with the TEC this can be avoided. Moreover the TEC has other secific uses also which will assist in the long term.
