Under the scheme, approved by the cabinet last month, all shopkeepers and self employed persons as well as retail traders with GST turnover below Rs 1.5 crore and aged between 18-40 years can enroll for the scheme.
"Currently, there are about 1.5 crore traders in the country who are near the age of 60 years and they should not be deprived from this scheme," Confederation of All India Traders (CAIT) said in a communication to Prime Minister Narendra Modi.
It has also suggested to give immediate effect to the scheme from next financial year.
"Large number of traders are not required to be registered under GST and as such they will also be deprived of the scheme," it said adding they should be included in the scheme which may be linked with their annual turnover.
"In this way, the scheme will cover traders comprehensively," it added.
