Several issues around the GSTN portal have been addressed and efforts are on to make the filing smooth, the network's chairman Ajay Bhushan Pandey said. In an interview to PTI, Pandey said a group of ministers (GoM) headed by Bihar Deputy Chief Minister Sushil Kumar Modi reviews the functioning of the GST Network (GSTN) every fortnight to ensure that it is working smoothly. The GoM will meet next on October 28 to review the actions taken to make the filing of GST process smooth. This will be the third meeting of the GoM since it was constituted in September.
