How to Protect Your Business From GST Notices, Scrutiny and Audit

Most GST notices today are not picked by an officer reading your file. The GST system compares your own returns with each other, with your suppliers' returns and with e-invoice and e-way bill data, and sends a notice when the numbers do not agree. So the best protection is simple: keep your books, your returns and your suppliers' data in agreement every month.

The notices businesses get most, and how to avoid each

"Set limit" for DRC-01B and DRC-01C is notified by the government and can change. If you get either one, explain or pay through Part B of the form on the portal; until you reply, GSTR-1 of the next period can be blocked.

What a delay costs

• Late fee for GSTR-3B and GSTR-1: Rs 50 a day (Rs 20 for a nil return), capped at Rs 2,000, Rs 5,000 or Rs 10,000 by turnover (Rs 500 for nil). CGST and SGST together.
• Late fee for GSTR-9: Rs 50, Rs 100 or Rs 200 a day by turnover, capped at 0.04% or 0.5% of turnover.
• Interest: 18% a year on tax paid late in cash, and 18% on ITC wrongly taken and actually used (section 50). Try the free interest & late fee calculator.
• Three-year bar: GSTR-1, GSTR-3B, GSTR-9 and other returns cannot be filed once three years have passed from their due date. An old unfiled return cannot be fixed later.
• Penalty under section 74A (FY 2024-25 onwards): without fraud, 10% of tax or Rs 10,000, whichever is higher; but no penalty if you pay tax and interest before the notice or within 60 days of it. With fraud or suppression, penalty equal to the tax.

15 habits that keep you out of trouble

• Enter bills daily, not at month-end. Late entry is where most missed bills and wrong dates come from.
• Keep masters clean: correct GSTIN, state and registration type for every party; correct HSN and rate for every item.
• Check a supplier before the first purchase: GSTIN active, returns filed. Free GSTIN checker.
• File GSTR-1 first, carefully. GSTR-3B sales come from it; fix mistakes in GSTR-1A before 3B.
• Act on IMS before the 14th so GSTR-2B shows the right bills.
• Claim ITC only from GSTR-2B, and only eligible credit. See choosing eligible ITC with BUSY.
• Pay suppliers within 180 days or reverse that ITC (Rule 37); MSME suppliers within 45 days for the income-tax deduction (43B(h) checker).
• Match e-invoices and e-way bills with the books. Cancel an unused e-way bill within 24 hours, and report e-invoices on time (businesses above Rs 10 crore turnover have a 30-day reporting window).
• Pay RCM in cash on legal fees, GTA and other notified services before taking its credit.
• Match GSTR-3B tax with the books every month; GSTR-3B vs books.
• Reconcile party ledgers with major customers and suppliers every quarter; differences become notices later.
• Keep cash and bank honest: no big cash sales without bills, no cash payments over Rs 10,000 to one party in a day (income-tax rule).
• Before the annual return, reconcile the whole year: sales, ITC, tax paid, stock. GSTR-9 / 9C from BUSY.
• Keep a monthly folder: returns filed, challans, 2B, reconciliation and working. Records must be kept for 72 months from the annual return due date.
• Never ignore a notice. Read the date by which a reply is due and reply on the portal, even if only to ask for time.

If a notice does come

1. Read it fully

   Note the form (ASMT-10, DRC-01B, DRC-01C, DRC-01...), the period, the amount and the last date for reply. Download it from the portal: Services > User Services > View Notices and Orders.

2. Find the cause in your books

   Most notices are a mismatch you can find in an hour: a bill in the wrong month, a supplier who did not file, a credit note missed, ITC claimed twice.

3. Pay what is really due

   If the department is right, pay tax and interest through DRC-03 quickly. Under section 74A, paying before the notice or within 60 days of it removes the penalty in non-fraud cases.

4. Reply with proof

   Where you are right, reply on the portal with a reconciliation, copies of bills, e-way bills and payment proofs. Keep the reply short and factual.

5. Take professional help for demands

   For a show cause notice, an audit or anything over a few thousand rupees, involve your CA or tax practitioner early.

How BUSY helps

BUSY keeps GSTIN, HSN and rates in the masters and prepares GSTR-1, GSTR-3B and GSTR-9 from your entries, so returns and books agree. Matching with GSTR-2B and party ledgers can be done inside BUSY with Bharat GST Champ and Bharat Darpan. Before every filing, run the GSTR-1 and GSTR-3B checklist.

General information, not legal advice. GST rules, limits and forms change often: check the latest notifications and GSTN advisories, and consult your CA or tax practitioner for any notice or demand.
