Around 56 per cent of the registered taxpayers filed their GSTR-3B returns for October within due date.
"The number of taxpayers filing their GSTR-3B returns is showing marked improvement month after month with about 43.67 lakh of them filing their GSTR-3B returns for October till November 20, 2017, the highest so far," GSTN said in a statement.

"There is a steady rise in the number of taxpayers filing their GSTR-3B returns every month which is encouraging to see. The trend of taxpayers filing their returns on the last day continues though. Taxpayers are urged to file their returns early to avoid last minute hassles," GSTN CEO Prakash Kumar said.
