GST is not a once-a-year obligation. Monthly or quarterly returns, annual reconciliation, and a running match between your books and the credit the portal shows in GSTR-2B — all of it has to line up. Most notices we see do not arise from tax evasion; they arise from mismatches that nobody reconciled for eight months.
Who needs this
- Every registered person, including those with nil turnover
- Businesses under the QRMP quarterly scheme
- Composition dealers filing CMP-08 and GSTR-4
- Exporters claiming refunds, where filing accuracy determines how fast money returns
Documents required
This is the usual list. Depending on your state and your specific facts, an authority may ask for more — we tell you at the scope stage rather than midway through.
- Sales register and issued invoices for the period
- Purchase register with supplier GSTINs
- Debit and credit notes issued or received
- Details of exports, exempt and reverse-charge supplies
- Previous period returns and the challans already paid
How we handle it
1. Reconciliation first
Purchases are matched against GSTR-2B before anything is filed. Credit that does not appear there is flagged to you with the supplier's name, so you can chase it while it is still recoverable.
2. Return preparation
GSTR-1 for outward supplies and GSTR-3B for summary and payment are prepared, with the tax position explained before you approve.
3. Filing and payment
Returns are filed against the due date and challans are generated for the payable amount.
4. Annual close
GSTR-9 and, where applicable, GSTR-9C are prepared from the full year's reconciled data rather than assembled at the last minute.
Fees and timeline
Recurring due dates: GSTR-1 by the 11th and GSTR-3B by the 20th for monthly filers. QRMP filers follow a quarterly cycle with monthly payment. Dates shift when the government grants extensions.

Common questions
What happens if a return is filed late?
Late fee accrues per day per return, and interest applies on unpaid tax. Beyond that, continued non-filing blocks e-way bill generation and can lead to registration cancellation.
A supplier has not uploaded my invoice. Can I still claim credit?
Credit is tied to what appears in GSTR-2B. If the supplier has not reported it, the practical route is to chase the supplier. We flag these month by month so the list stays short.
Do I have to file if there were no sales?
Yes. A nil return is still a return, and the late fee applies to nil filings as well.
