All servicesGST
Returns filed on time, input credit reconciled properly, and the process fixed where the same errors keep appearing.
Most GST trouble is not caused by the return itself. It comes from upstream: invoices raised with the wrong place of supply, purchases recorded against the wrong GSTIN, credit notes not linked, or vendors who do not file. By the time it shows up as a mismatch in the return, the fix is far more expensive.
We handle the full compliance cycle and treat reconciliation as the centre of the work — matching purchase records against what vendors have actually reported, chasing the gaps while they can still be corrected, and documenting what was claimed and why.
Where a business has recurring mismatches, we run a health check across a past period, quantify the exposure, and change the invoicing and recording process rather than only filing a corrected return.
What you receive
Scope of work
The cycle
The filing is the visible part. The work that decides whether the filing is correct happens before it.
Credit is claimed in the books that the vendor never reported. It looks fine until the reconciliation, and by then the return has been filed.
Reconciling before filing — rather than after a department query — is the single change that removes most recurring GST problems.

Which of these apply to you depends on your registration, turnover and scheme. Due dates are amended from time to time and extensions are notified during the year, so treat this table as orientation rather than as the current statutory position. We confirm the dates that apply to your entity when we set up your compliance calendar.

Every month
Whatever the month, the rhythm is the same. These are the days that matter, and they do not change.
| Day | Obligation | What it covers |
|---|---|---|
| 7th | TDS & TCS payment | Income tax deducted or collected during the previous month. |
| 10th | GSTR-7 and GSTR-8 | GST TDS, and TCS collected by e-commerce operators, for the previous month. |
| 11th | GSTR-1 | Outward supplies for the previous month — monthly filers. |
| 13th | GSTR-6, and IFF for QRMP filers | Input service distributor return; optional invoice furnishing under QRMP. |
| 14th | GSTR-2B becomes available | Auto-drafted input credit statement. Not a filing — this is when you reconcile. |
| 20th | GSTR-3B | Summary return and tax payment for the previous month — monthly filers. |
| 25th | PMT-06 | Monthly tax payment for QRMP filers, in the first two months of a quarter. |
Quarterly and annual dates sit on top of this — CMP-08 and the QRMP returns after each quarter, advance tax in June, September, December and March, and the annual return in December. We set all of them out as a calendar for your entity when an engagement starts.

Questions
Beyond filing returns: determining whether and where you need to register, reconciling input tax credit against vendor filings, advising on classification and place of supply, responding to notices, and correcting the invoicing and recording process that produced the problem in the first place.
Usually because the credit claimed in your books is not matched by what your vendors have reported, or because invoices are recorded against the wrong GSTIN or period. A reconciliation exercise across a few months normally identifies the pattern — and it is generally a vendor or a data-entry issue rather than an isolated error.
A review of a past period — commonly a financial year — comparing your books, returns and reconciliation statements to identify under-reported liability, credit claimed but not eligible, and documentation gaps. It gives you a quantified picture of exposure before a department query does.
Yes. We review the notice, assemble the supporting records, prepare a reply with annexures, and handle the follow-up. Send the notice and the relevant returns; the response deadline usually sets the pace of everything else.
