A stock mismatch is no longer just an accounting headache. Under GST, the stock in your books, the stock in your godown and the figures in your returns are all expected to tell the same story. When they do not, a GST officer can ask why, and the answer can cost you input tax credit, tax on presumed sales, interest and penalty.
This guide explains where GST risk comes from, what the law says about lost and stolen goods, and a simple stock reconciliation process to keep your numbers aligned.
This article is general information, not legal or tax advice. Please confirm the treatment for your business with your CA.
Why stock mismatches attract GST attention
GST returns are built from invoices, and purchases are matched through the credit system. Your stock position can be worked out from opening stock, purchases and sales. If physical stock found during an inspection or audit is lower than book stock, the department may treat the shortage as goods sold without an invoice. If it is higher, the excess may be treated as purchases made outside the books.
Common triggers include inspections and surveys at the premises, departmental audits under Section 65 (which include physical verification of stock), and mismatches between GSTR-9 annual return figures and the financial statements.
What the law says about lost, stolen or destroyed goods
Section 17(5)(h) of the CGST Act blocks input tax credit on goods that are lost, stolen, destroyed, written off or disposed of by way of gift or free samples. If you already claimed ITC on such goods, you must reverse it, and interest applies where the credit was used.
In practice:
- Identify the quantity and value of goods lost, stolen or destroyed
- Work out the ITC originally claimed on them
- Reverse that ITC in GSTR-3B for the relevant period
- Keep evidence: physical verification records, police report for theft, survey report for damage, insurance correspondence
Reporting stock in GSTR-9
GSTR-9 (the annual return) includes details that link to your stock position, and many businesses also show closing stock as at 31 March in the reconciliation with audited accounts. Large differences between what your books, your returns and your financial statements say are an easy red flag.
The cost of getting it wrong
If a shortage is treated as unrecorded supply, tax is demanded on it with interest at 18% per annum. Penalty depends on the case: for non-fraud cases it is generally 10% of the tax or ₹10,000, whichever is higher, and for cases involving fraud or suppression it can be equal to the tax. For demands from FY 2024-25 onwards these are handled under Section 74A; earlier periods fall under Sections 73 and 74. Your CA can confirm which applies.
Stock reconciliation: what it means
Stock reconciliation is the process of matching three numbers and explaining every difference:
- Book stock, from your accounting system (Tally or ERP)
- Physical stock, from an actual count
- Return figures, from your GST returns and annual statements
Stock reconciliation process: step by step
Step 1: Fix a cut-off date
Usually month end, quarter end or 31 March. Stop or separately record movement after the cut-off.
Step 2: Count physical stock
Run a physical stock verification by item and location. See our full physical stock verification guide.
Step 3: Pull book stock
Export the Stock Summary as at the cut-off date, item-wise and godown-wise.
Step 4: Compare and classify differences
For each item, classify the difference as timing (goods in transit, pending GRN or invoice), error (wrong item, unit or rate), or real loss or gain (theft, damage, expiry, excess supply).
Step 5: Correct the books
Fix posting errors at source. Record real losses through a loss account, and reverse ITC on goods lost, stolen or destroyed.
Step 6: Tie back to returns
Check that purchases and sales in the books match GSTR-1, GSTR-3B and the credit statement, and that closing stock agrees with the financial statements and annual return working.
Step 7: Document everything
Keep count sheets, approvals, reasons and evidence together. A clean file is the best defence in an audit.
Stock reconciliation statement format
| Item | Book qty | Physical qty | Difference | Classification | Value (₹) | ITC to reverse (₹) | Action and evidence |
|---|---|---|---|---|---|---|---|
| Item A | 500 | 480 | -20 | Theft | 24,000 | 4,320 | Reverse ITC; FIR attached |
| Item B | 120 | 124 | +4 | Pending invoice entry | 3,200 | 0 | Post purchase bill |
(Example figures only; ITC shown at 18%.)
How to keep stock and GST aligned all year
- Count stock monthly or quarterly instead of once a year
- Reconcile book stock with physical stock after every count
- Reverse ITC in the same month a loss is confirmed
- Keep a damaged and expired goods register
- Reconcile purchases with the credit statement every month
How TrueStock helps
TrueStock counts RFID-tagged stock in hours, compares the count with your Tally book stock and shows differences item by item and godown by godown. Because counting becomes quick, you can reconcile every month instead of discovering a shortage during a GST audit. Learn how to do stock reconciliation in Tally with the TrueStock integration.
Conclusion
Under GST, stock is evidence. Count often, reconcile every difference, reverse ITC on genuine losses and keep your records audit-ready.
Make every stock count audit-ready.
Frequently asked questions
What happens if physical stock is less than book stock under GST?
The shortage may be treated as goods supplied without an invoice, with tax, interest and penalty demanded, unless you can explain it with records.
Is ITC reversed on stolen goods?
Yes. Section 17(5)(h) of the CGST Act blocks ITC on goods lost, stolen, destroyed or written off, so credit already claimed must be reversed.
What is stock reconciliation?
Matching book stock, physical stock and return figures, then explaining and correcting every difference.
How often should stock be reconciled?
At least quarterly; monthly is better for businesses with high stock values or bank limits.
Does physical stock verification happen in a GST audit?
It can. Audits under Section 65 and inspections may include physical verification of stock.
