What’s Included in GST Filing
Every GST return your business is required to file — prepared, reconciled and submitted for you.
GSTR-1 — Outward Supplies
Filing of your sales / outward supply return, monthly or quarterly under QRMP, with accurate invoice-level detail so your buyers get their input credit.
GSTR-3B — Summary & Tax Payment
Preparation and filing of the monthly / quarterly summary return with correct tax liability, input credit set-off and challan payment.
QRMP Scheme
Quarterly Return Monthly Payment management for eligible small taxpayers (turnover up to ₹5 crore) — quarterly GSTR-1 & 3B with monthly PMT-06 challans.
Annual Return — GSTR-9 / 9C
Annual return GSTR-9, and the GSTR-9C reconciliation statement where turnover exceeds the threshold, reconciled against your books.
ITC Reconciliation (2A / 2B)
Monthly reconciliation of your purchase register against GSTR-2A / 2B so you claim every eligible rupee of input tax credit and avoid mismatches.
Nil Return Filing
Timely nil GSTR-1 and GSTR-3B filing for dormant or zero-activity periods, so late fees never accrue on a quiet month.
LUT for Exporters
Filing of the annual Letter of Undertaking (LUT) so exporters and SEZ suppliers can supply at zero-rated GST without paying IGST upfront.
Notices & Reconciliation Support
Help responding to GST mismatch notices and reconciling your filed returns with your books and e-invoices.
