"This is one sector where we have beaten the world. Today the sector is facing challenges overseas including protectionism and anti-globalisation.
"While government support on global issues has been exemplary, it will be ironic if GST reform implementation is such that it throws up crippling operational challenges for the sector," Nasscom President R Chandrashekhar told PTI.
Such operational challenges could undermine global competitiveness of the sector, he cautioned.
Nasscom contends that challenges for the IT sector arise because a single IT service contract may have multiple locations where an intangible service is delivered to and from -- be it domestic or exports.

Complex place of supply, input credit and valuation requirements, in addition to multiple registration, is leading to an unviable situation, Nasscom said.
"This is for companies that have pan India operations to enable centralised single point billing and to minimise multiple avoidable transactions for export contracts," Nasscom has said.
This would also require appropriate changes to place of supply rules, it added.
Expressing concern over classification of software, Nasscom said, "We thought that the debate over software being a service or a good was laid to rest, with the release of the initial model law, where intangibles were classified as services. Unfortunately this has been resurrected in the revised model law."
