Why Online Sellers Get GST Notices: 5 Triggers and How to Avoid Them

Most GST notices to online sellers come from five triggers the system checks every month: tax in GSTR-1 higher than tax paid in GSTR-3B, credit claimed above GSTR-2B, marketplace figures that differ from yours, returns not filed, and credit you should have reversed. A short check before each filing avoids nearly all of them.

Why do online sellers get more notices?

Because more people report on you. You file GSTR-1 and GSTR-3B. Your suppliers' returns build your GSTR-2B, the monthly statement of credit available to you. And every marketplace files GSTR-8, which shows what you sold through it and the TCS (tax collected at source) it held back. Three sources, compared by machine, every month. A shop selling only offline has one.

The good news is that each trigger is predictable. The table shows all five.

Trigger 1: GSTR-1 shows more tax than GSTR-3B

When the tax in your GSTR-1 is higher than the tax you paid in GSTR-3B by more than a limit the GST Council sets, rule 88C sends Part A of DRC-01B. Until you pay or reply, rule 59(6) stops you from filing your next GSTR-1. Declaring more sales in GSTR-1 than in GSTR-3B is also listed in rule 21 as a ground on which registration can be cancelled. The reply process is in our guide to the DRC-01B reply.

For sellers the cause is almost always one of two things: GSTR-3B was filed from the bank payout or a rough total, or one marketplace's report was left out of it.

Trigger 2: credit claimed above GSTR-2B

Rule 88D works the same way for input tax credit, the GST you paid on purchases and set off against tax on sales. Claim more in GSTR-3B than GSTR-2B shows, beyond the Council's limit, and you get DRC-01C with seven days to pay or explain. If you do neither, the amount can be demanded through a show cause notice. A supplier who files late is the usual reason. Wait for the invoice to reach GSTR-2B before you claim it.

Trigger 3: marketplace figures that differ from yours

Section 52 says the supplies a marketplace reports are matched with what you report. A discrepancy is told to both sides. If you do not fix it and the marketplace's figure is higher, the difference is added to your tax with interest. Cancelled and returned orders are the usual cause. The month by month method is in matching GSTR-8 with GSTR-1.

Trigger 4: returns not filed

A missed return brings a GSTR-3A reminder under rule 68. Keep missing them and rule 21 makes your registration liable to cancellation: six months in a row for a monthly filer, two tax periods for a quarterly filer. Without a valid registration you cannot go on selling as a registered seller. Late fee and interest also build up from the due date. See late fees for GSTR-1 and GSTR-3B for the current amounts.

Trigger 5: credit you should have reversed

Two cases catch sellers. Under rule 37A, if a supplier reported your invoice in GSTR-1 but has not filed GSTR-3B for that period by 30 September after the year, you reverse that credit in a GSTR-3B filed by 30 November. After that, it is payable with interest. You can claim it again once the supplier files.

The second case is stock. Section 17(5)(h) blocks credit on goods lost, stolen, destroyed, written off, or given as gifts or free samples. Damaged customer returns that you throw away fall here. The GST Council has proposed easing parts of this block, but that is not law yet. More detail is in ITC reversal rules.

A worked example

Sana sells kitchen storage on three marketplaces. In October her purchase register shows credit of Rs 42,000, but GSTR-2B shows Rs 30,000, because her carton supplier filed late. If she claims Rs 42,000, the Rs 12,000 gap may bring DRC-01C. She claims Rs 30,000 now and the Rs 12,000 next month, once it appears. Cost of waiting: nothing.

In the same month she writes off 60 returned units that arrived broken. The credit she took when she bought them was Rs 2,700. She reverses it. If she does not, the credit she holds is more than her stock supports, and a scrutiny notice can ask for Rs 2,700 with interest, plus her time explaining it.

A monthly check before you file

1. Total taxable sales and tax from every marketplace report, less returns. Use the same figures for GSTR-1 and GSTR-3B.
2. Take credit only up to what GSTR-2B shows for the month.
3. Open the TCS credit received screen and compare each marketplace's net figure with yours before accepting.
4. Note any goods written off or given free, and reverse their credit.
5. Before 30 November, list suppliers who have not filed GSTR-3B and reverse that credit.
6. File both returns by the due date, even when there were no sales.

The mistake sellers usually make

They treat the marketplace payout as their sales. The payout is after commission, shipping, returns, TCS and TDS, so it never matches GSTR-1 or GSTR-8. Build returns from the sales reports, not the bank statement. The trigger list in our Seller Intelligence report started this article.
