While prima facie, the GST rate does appear higher than the current taxation regime, the availability of input tax credit under the GST will neutralise the impact of higher taxes, Icra said in its report on 'Impact of GST on Corporate Sector'.
"Under GST, the composite supply of works contracts fall under the 18 per cent GST rate with full input tax credit (ITC). While prima facie, the GST rate does appear higher than the current taxation regime, in which majority of construction contracts fall under the nature of work contracts (which is overlapping between supply of services and supply of goods) and a combination of service tax and VAT is applicable," Icra said.
However, the agency said, many construction activities (like construction of roads, dams, irrigation) are under service tax exemption list and the VAT payable varies across states ranging from 1-15 per cent and is applicable on the supply of goods portion of the contract.
Thus, the effective tax incidence for an average construction contract in the pre-GST era is typically in the range of 11-18 per cent, which is lower in comparison to the announced GST rate of 18 per cent. The difference is more pronounced for the construction services which fall under the service tax exemption category, it said.
For infra projects under implementation, the GST rates could result in an increase in cost, if there is insufficient built in contingency factor and limited scope for contract renegotiation. For example, currently construction of road for public is exempt from service tax, but this does not appear in the GST exemption list and could result in increase in construction cost for the project, the report explained.
