"In order to resolve the same, emergency maintenance is being carried out on the system. Therefore, in the interest of taxpayers it has been decided to extend the last date for filing of returns in GSTR-3B for the month of April by 2 days till May 22," the statement said.
The goods and services tax (GST) mop-up in April -- the first month of current fiscal -- came in at Rs 1.03 lakh crore.
From 2018-19 fiscal year that began last month, the government has shifted to a cash basis of accounting where revenues accrued at the completion of a month would be taken on record immediately at the end of the month.
Meanwhile, GST Tech, which is the official twitter handle for IT related queries on GST tweeted: "Due to emergency maintenance activity, GST Portal will be unavailable on 18th May, 2018, from 2:45 PM to 3:15 PM".
