What is Form GSTR-1?
Form GSTR-1 is a monthly or quarterly return where every registered business needs to report details of their outward supplies — that is, sales of goods or services. This includes invoices, debit notes, credit notes, and any revised invoices.
Who is required to file GSTR-1?
All GST registered businesses must file GSTR-1 except:
✅ Input Service Distributors (ISD)
✅ Non-resident taxable persons (NRTP)
✅ Composition Scheme dealers
✅ Persons registered for TDS or TCS under GST
✅ Providers of OIDAR (Online Information & Database Access) services
What is IFF (Invoice Furnishing Facility)?
Businesses under the QRMP scheme (Quarterly Return Monthly Payment) with turnover up to ₹5 crore can use IFF to report B2B sales invoices for the first two months of a quarter. This ensures that their customers can claim input tax credit on time.
Do I need to file GSTR-1 even if there are no sales?
Yes. Even if there are no sales during the period, a Nil GSTR-1 must be filed.
When can GSTR-1 filing be restricted?
You cannot file GSTR-1 or use IFF in the following cases:
✔️ If GSTR-3B for the previous period is not filed
✔️ If GSTR-1 for the previous period is pending
✔️ If you’ve received a tax mismatch notice (DRC-01B) and haven't responded or paid the difference
✔️ If there's a mismatch in ITC claimed (DRC-01C) and you haven't responded or paid
✔️ If bank account details are not updated after GST registration

If I declare sales in GSTR-1 but don't pay tax in GSTR-3B, what happens?
In that case, it's treated as self-assessed tax liability. The department can initiate recovery proceedings for the unpaid amount.
What is Form DRC-01B and DRC-01C?
· DRC-01B – Sent if tax declared in GSTR-1 is more than GSTR-3B. You must pay the difference or explain within 7 days.
