Pakistan Hardware Merchants Association (PHMA) Thursday urged the Federal Board of Revenue to give logic for implementation of much controversial SRO 821(I) 2011 as business community considers this SRO unjustified and illogical. Speaking a video conference with Central Vice Chairman PHMA Tariq Rasheed, Zonal Chairman Sheikh Ahmad Daud and other zonal offices, the Central Chairman of Pakistan Hardware Merchants Association Sardar Usman Ghani said the SRO would not be doing any service to the Federal Board of Revenue (FBR) rather it would further tighten noose around the registered tax payers only. He said SRO 821(I) 2011 will have devastating effect on the businesses in Pakistan as the compulsory requirement of NTN or CNIC number of each and every purchaser or seller is practically almost impossible.
