GST returns & filing pack
Prepare a month for GST filing — pre-filing checks, the HSN summary, B2B sales by customer, the downloadable CA pack, and recording the ARN once your CA files.
Kapda Stock does not file returns. It gets the month's numbers right, flags problems, packages everything for your CA, and keeps a record of what was filed.
Prepare the month#
Open GST & Compliance and pick the month and year. Figures cover issued invoices dated in that month (IST); drafts, cancelled invoices and proformas are excluded.
Pre-filing checks#
Before this goes to your CA lists problems found in the month's bills. Each check shows a hint and example invoices (and N more). Blocking problems are shown first.
| Check | What it means |
|---|---|
| Customer GSTIN is not a valid number | The portal rejects the whole return over one malformed GSTIN. Correct it on the customer before your CA files. |
| Items sold without an HSN code | A line has no HSN code. |
| Tax type does not match the customer's state | Intra-state sales take CGST + SGST; inter-state take IGST. Check the customer's GSTIN state code. |
| Taxable invoices carrying no GST | Fine for exempt goods — otherwise the tax was missed. Worth a look before the figures go to your CA. |
| Large B2B invoices with no e-invoice IRN | Invoices above ₹2,50,000 without an IRN. |
| Large sales recorded without a GSTIN | Sales above ₹2,50,000 to a customer with no GSTIN — if the buyer is a business, add their GSTIN so they can claim input credit — and so the sale reports as B2B. |
When nothing is flagged you see: Every invoice in (month) has a valid GSTIN where one is needed, an HSN code on every line, and tax that matches the customer's state. Download the pack and send it on.
Fix problems at the source — the customer's GSTIN in Customer profiles — then reload.
HSN summary#
Quantity and tax per HSN code and rate — table 12 of GSTR-1, built from the month's bills.
Columns: HSN, Description, UQC (unit), Qty, Rate, Taxable, CGST, SGST, IGST.
B2B sales by customer#
These buyers will look for your invoices in their GSTR-2B — a mismatch here is the call you get next month.
Columns: GSTIN, Customer, Invoices, Taxable, Tax.
Download the CA pack#
Download the CA pack exports one workbook: summary, invoice register, HSN summary, B2B ledger, checks and the raw GSTR figures. Send it to your CA for filing.
The GST snapshot on the Reports hub shows this month's GSTR-3B headline figures at a glance.
Record a filed return#
After your CA files on the GST portal:
- In Filing record, click Record GSTR-1 or Record GSTR-3B.
- Enter the ARN the portal gave for that month — Enter the ARN the GST portal gave your CA for GSTR-1 MM/YYYY — for example
AA0107260012345(two letters followed by 13–16 digits). - You see GSTR-1 recorded for MM/YYYY.
Returns are filed by your CA on the GST portal. Record the ARN here so you always know what has gone in, and for which month. The table shows Return, Period, Status, ARN and Recorded (IST).
Each return can be recorded once per month: GSTR-1 for MM/YYYY is already recorded (ARN …).
