Frequently Asked Questions
1. Can GSTR-1 be filed if the previous GSTR-3B is pending?
A taxpayer may be restricted from furnishing GSTR-1 or using IFF if the required GSTR-3B for the preceding tax period has not been filed. Taxpayers should clear pending returns before attempting the next filing.
2. Can a taxpayer furnish invoices through IFF after filing GSTR-3B for the same month?
IFF is available only for the first two months of a quarter. Invoices not successfully furnished through IFF should be reported in the quarterly GSTR-1 within the prescribed timeline.
3. Is a taxpayer required to file GSTR-7 if no tax has been deducted under GST during July 2026?
No. GSTR-7 is required only when tax has actually been deducted under Section 51 of the CGST Act, 2017 during the relevant tax period.
4. Can a composition taxpayer file GSTR-3B instead of CMP-08?
No. A taxpayer registered under Section 10 (Composition Scheme) is required to furnish CMP-08 and GSTR-4, as applicable. Filing GSTR-3B is meant for regular taxpayers and does not substitute composition compliance.
5. If an Input Service Distributor (ISD) does not receive any inward services during July 2026, is GSTR-6 still required?
Yes. An Input Service Distributor is generally required to furnish GSTR-6 for every tax period during which the registration remains active, even if there is no ITC available for distribution.
6. Can a QRMP taxpayer opt for the Fixed Sum Method while depositing tax through PMT-06 even if actual liability is lower?
Yes. Under the Fixed Sum Method, the taxpayer may deposit 35% of the tax paid in cash in the previous quarter (or 100% of the previous month’s cash tax, as applicable). Any excess payment is adjusted while filing GSTR-3B for the quarter.
7. Can GSTR-5 be filed after the registration of a Non-Resident Taxable Person (NRTP) has expired?
Yes. An NRTP is required to furnish GSTR-5 within 13 days after the end of the calendar month or within seven days after the expiry of registration, whichever is earlier.
8. Is GSTR-8 required to be filed if an e-commerce operator has made no taxable supplies during July 2026?
Yes. An e-commerce operator liable to collect TCS under Section 52 of the CGST Act is generally required to furnish GSTR-8 even if there are no supplies liable for TCS during the tax period, unless otherwise exempt.
9. Can Ebizfiling assist in identifying blocked ITC before filing GSTR-3B for August compliances?
Yes. Ebizfiling assists businesses in reconciling purchase registers with GSTR-2B, identifying ineligible or blocked ITC under Section 17(5) of the CGST Act, and validating eligible credits before filing GSTR-3B.
10. Does Ebizfiling help businesses reconcile GSTR-1, GSTR-3B, GSTR-2B, and e-Invoice data before filing August 2026 GST returns?
Yes. Ebizfiling provides end-to-end GST compliance support, including reconciliation of GSTR-1, GSTR-3B, GSTR-2B, e-Invoice data, books of accounts, and tax liability, helping businesses minimize reporting errors and reduce the risk of GST notices.
