Introduction
GST Return Filing is the mandatory process of reporting your business's sales, purchases, output GST collected, and Input Tax Credit (ITC) claimed to the government. Every GST-registered business in India must file GST returns on a monthly or quarterly basis, depending on their turnover and registration type.
A2Z Accounting & Tax Firm provides comprehensive GST return filing services starting at ₹5,000/month, including GSTR-1, GSTR-3B filing, ITC reconciliation with GSTR-2B, and e-Way bill advisory.
What is GST Return Filing?
GST Return Filing is the process of submitting periodic returns to the GST department detailing all sales (outward supplies), purchases (inward supplies), tax collected, and Input Tax Credit (ITC) availed. The primary returns are GSTR-1 (sales return), GSTR-3B (summary return with tax payment), and GSTR-9 (annual return).
Why is GST Return Filing Important?
- Legal Requirement — Non-filing of returns attracts late fees of ₹50/day (₹20/day for NIL returns) and interest at 18% per annum
- Input Tax Credit — ITC can only be claimed by filing timely returns
- Avoid Registration Cancellation — Non-filing for 6 consecutive months leads to suo-moto cancellation of GSTIN
- GSTR-2B Reconciliation — Ensures ITC claimed matches supplier-uploaded invoices, preventing demand notices
- Compliance Rating — Regular filing improves your GST compliance rating, which affects your business reputation
