GST return filing is a monthly (or quarterly) compliance requirement for all GST-registered businesses. Returns include GSTR-1 (outward supply details), GSTR-3B (summary return with payment), and GSTR-9 (annual return). Missing deadlines attracts daily penalties and interest on unpaid tax.
Critical: GSTR-1 must be filed before GSTR-3B — if GSTR-1 is not filed, your buyers cannot see your invoices in their GSTR-2B and their ITC is blocked. Persistent non-filing of GSTR-1 results in your customers switching to compliant suppliers, directly impacting your business revenue.
Invoice-wise sales details
GSTR-1 reports all outward supplies (sales) made during the month — customer-wise for B2B and aggregate for B2C. Must be filed by the 11th of next month (or quarterly for QRMP registrants).
Net tax payment each month
GSTR-3B is the monthly summary return where you report total supplies, ITC claimed, and net GST payable. Tax must be paid along with this return by the 20th of each month.
Match supplier invoices
ITC can only be claimed for invoices reported by your suppliers in their GSTR-1. We reconcile your purchase data with GSTR-2B monthly to maximize eligible ITC claims and catch supplier defaults.
Quarterly returns for small businesses
Businesses with aggregate turnover below ₹5 crores can opt for the QRMP (Quarterly Return Monthly Payment) scheme — filing GSTR-1 and GSTR-3B quarterly while paying tax monthly.
All GST-registered businesses must file returns even in periods of no business activity.
Every business with a regular GSTIN must file GSTR-1 and GSTR-3B monthly (or quarterly under QRMP). This applies even for months with zero transactions — a 'NIL' return must be filed.
Composition scheme registrants file Form CMP-08 (quarterly statement) and GSTR-4 (annual return) — much simpler than regular returns.
E-commerce operators (like Amazon, Flipkart) file GSTR-8 for TCS collected from sellers. Sellers on these platforms must also reconcile TCS credit in their own returns.
Non-resident taxable persons (foreigners with temporary GST registration) file GSTR-5 during their registration period.
GST mistakes compound quickly — interest, penalties, and blocked ITC add up to significant financial losses.
We reconcile your purchases with GSTR-2B monthly — ensuring you claim every rupee of eligible ITC without over-claiming, which triggers department scrutiny.
Discrepancies between your GSTR-1 (invoices) and GSTR-3B (payment) generate automated notices. We ensure perfect internal consistency across returns.
Late filing attracts ₹50 per day (₹20/day for nil returns) — capped at ₹5,000 per return. But with 12–24 returns per year, penalties quickly exceed ₹25,000–₹50,000 for a non-filer.
Rule 86A allows the department to block ITC for suspicious claims. We maintain proper documentation and supplier compliance to prevent ITC blocking.
Exporters and inverted duty structure businesses can claim GST refunds — but only if returns are filed correctly and on time. We manage the entire refund cycle.
Annual GSTR-9 must match the aggregate of all monthly GSTR-1 and GSTR-3B filings. Monthly accuracy prevents complex year-end reconciliation adjustments.
