How the work is done — five clear stages

You’ll know which stage you’re at, from the first call through to a checked submission and a clear outcome.

Collect sales, purchase and ledger data

We collect the period’s sales, purchases, credit and debit notes, cancelled invoices and reverse-charge records, and identify missing information.

For the applicable regular-taxpayer route, we prepare GSTR-1 or IFF and reconcile purchase records with GSTR-2B, including relevant invoice-management actions.

Prepare GSTR-3B

We work out output tax, eligible input credit, reversals and reverse charge, then share the draft GSTR-3B figures and any net tax payable.

4

File GSTR-3B

After you approve the figures and arrange payment, we submit GSTR-3B using the applicable authentication and confirm the portal filing status.

5

File and preserve ARN and reconciliation records

We share the filed return, acknowledgement and reconciliation summary, highlighting supplier follow-ups or corrections to carry into the next review.

Questions people ask us most

GST Return Filing FAQs

Do I need to file a GST return when there are no sales?

Normal and casual taxpayers generally still need to file the applicable return for the period. A nil GSTR-3B is available only when the official nil-return conditions are satisfied, including no outward supply, reverse-charge liability, ITC claim or other liability.

Can a filed GST return be revised?

A filed GSTR-3B cannot simply be reopened and revised. Corrections may need to be reported through the permitted facility or a later open period. For the same period, optional GSTR-1A may correct or add outward-supply records after GSTR-1 and before GSTR-3B.

What is the difference between GSTR-1 and GSTR-3B?

GSTR-1 reports outward-supply details. GSTR-3B is the summary return used to declare liability, eligible ITC and tax payment. The figures should be reconciled before filing.

What is GSTR-2B and why is it checked?

GSTR-2B is an auto-drafted ITC statement based on supplier reporting and portal processing. It is compared with purchase records before eligible ITC is considered.

What is the Invoice Management System?

IMS allows recipients to accept, reject or keep applicable supplier documents pending so that input-credit records are handled correctly. Actions should be reviewed before GSTR-2B and GSTR-3B are finalised.

Is QRMP a quarterly-only compliance process?

No. Eligible taxpayers file GSTR-1 and GSTR-3B quarterly, but tax is paid in the first two months through PMT-06. Optional IFF may also be used for B2B documents.

What happens when GST returns are filed late?

Late fee may apply to the delayed return and interest may apply to delayed tax payment. Continued non-filing can also lead to notices and other portal restrictions. The exact position should be checked for the GSTIN and period.
