GST on Marketplace Purchases: Invoice Checks

When you buy from an online marketplace, the invoice you receive should clearly show the GST charged, the seller’s GSTIN, and the marketplace’s role in the transaction. Before you pay, check that the invoice is valid for input tax credit (ITC) if you are a business, and that the GST rate applied matches the product category. This article explains exactly what to look for on a marketplace invoice, how GST works on these platforms, and what to do if something looks wrong.

How GST Applies to Marketplace Purchases

In India, the Goods and Services Tax (GST) is a destination-based tax on the supply of goods and services. Under the GST framework, electronic marketplaces like Amazon, Flipkart, and Myntra are treated as “electronic commerce operators” (ECOs). The GST law mandates that the ECO collects tax at source (TCS) on net taxable supplies made through its platform. This means the marketplace is responsible for collecting a small percentage of the value of each sale and remitting it to the government. However, the actual GST on the sale (CGST, SGST, or IGST) is charged by the seller, not the marketplace. The invoice you receive should therefore be issued by the seller, but the marketplace’s TCS amount is often shown separately.

For most consumers (non-business buyers), the GST charged is a final cost. You cannot claim it back. For businesses registered under GST, the GST paid on purchases can be claimed as input tax credit, provided the invoice meets all the conditions under Section 16 of the CGST Act. This is why checking the invoice is critical for business buyers.

Key Fields to Check on a Marketplace Invoice

Not every field on an invoice is equally important. Here is a checklist of what to verify:

Seller’s GSTIN: This must be a valid 15-character GSTIN. The first two digits are the state code, the next ten are the PAN, the 13th is the entity code, and the 14th is ‘Z’ by default. The 15th is a checksum digit.
Invoice number and date: Must be unique and sequential. The date is the time of supply for GST purposes.
Place of supply: For goods, this is usually the delivery address. For services, it is the location of the recipient. This determines whether CGST+SGST or IGST applies.
GST rate and amount: The invoice should clearly state the rate (e.g., 5%, 12%, 18%, 28%) and the tax amount separately for each item. It should also show the taxable value (price before tax).
HSN code: The Harmonized System of Nomenclature code for the product. This helps verify the correct tax rate.
Marketplace TCS: A separate line item showing the TCS collected by the marketplace (usually 0.5% CGST + 0.5% SGST for intra-state, or 1% IGST for inter-state). This is not an additional cost to you; it is an advance tax collected from the seller, but it appears on your invoice for transparency.
Seller’s name and address: Should match the entity that actually supplies the goods.

Why the GST Rate on Your Invoice Might Be Wrong

A common issue is that the GST rate on the invoice does not match the rate for the product you bought. This can happen when the seller misclassifies the product under the wrong HSN code. For example, a laptop bag might be taxed at 18%, but if the seller codes it as a travel bag, it could be 28%. Conversely, a seller might under-charge GST to make the product look cheaper, but then you cannot claim ITC if you are a business. Always compare the HSN code on the invoice with the official GST rate schedule. If the rate is wrong, ask the seller to issue a credit note and a fresh invoice with the correct rate.

How to Verify a GSTIN on an Invoice

You can verify the seller’s GSTIN on the official GST portal (gst.gov.in) using the “Search Taxpayer” feature. Enter the GSTIN and check that the legal name matches the seller name on the invoice. Also, check that the GSTIN is active, not cancelled. A cancelled GSTIN means the seller is not registered, and any tax collected on the invoice is not valid. For a business buyer, this invalidates the ITC claim.

Common Problems with Marketplace Invoices

Missing HSN code: For invoices above a certain value, HSN codes are mandatory. If missing, the invoice is not valid for ITC.
Invoice from the marketplace, not the seller: Some marketplaces issue a consolidated invoice in their name. This is only valid if the marketplace is the actual supplier (e.g., Amazon Retail). If it is a third-party seller, the invoice must be from that seller.
Wrong place of supply: If the invoice shows the wrong state, the tax type (IGST vs CGST+SGST) will be wrong. This can cause problems when claiming ITC across states.
GSTIN with a different name: The name on the GSTIN must match the seller’s trade name. If not, the invoice is invalid.

What to Do If the Invoice Is Incorrect

If you spot an error, do not ignore it. For a business, an incorrect invoice means you cannot claim ITC, which directly increases your cost. Contact the seller first. Ask for a revised invoice with the correct details. If the seller does not respond, escalate to the marketplace’s customer support. Marketplaces have seller-rating systems and can force a correction. For a consumer, an incorrect GST rate might mean you overpaid tax. You can request a refund of the difference from the seller. If the seller refuses, you can file a complaint on the GST portal or with the consumer forum.

Marketplace TCS vs. Seller GST: What’s the Difference?

It is easy to confuse TCS with GST. TCS is collected by the marketplace under Section 52 of the CGST Act. It is not a tax on the buyer; it is a mechanism for the government to track transactions. The seller pays the actual GST on the sale, and the TCS is adjusted against the seller’s GST liability. On your invoice, you will see both. The TCS amount is not an additional cost to you—it is part of the total price you pay. But for a business buyer, the TCS is not available as ITC. Only the GST charged by the seller is creditable. So, when you claim ITC, use the GST amount, not the TCS.

Frequently Asked Questions

Can I claim ITC on a marketplace purchase without a GST invoice?

No. To claim input tax credit, you must have a tax invoice that contains all the prescribed particulars: seller’s GSTIN, your GSTIN, description of goods, value, tax rate, and amount. A simple payment receipt or order confirmation is not sufficient.

What if the invoice shows a different GST rate than what I was charged?

Check the HSN code and the GST rate schedule. If the rate is incorrect, the seller must issue a credit note and a new invoice with the correct rate. You should not pay a higher rate than applicable, and if you are a business, you can only claim ITC at the correct rate.

Why does my invoice show a TCS amount from the marketplace?

This is the Tax Collected at Source by the e-commerce operator. It is a statutory requirement. It is not an extra charge to you; it is an advance tax remitted to the government on behalf of the seller. The seller can claim this as a credit when filing their GST returns.

Can a marketplace issue the GST invoice instead of the seller?

Yes, but only if the marketplace is the actual supplier of the goods (e.g., Amazon Retail, Flipkart SmartBuy). If the sale is from a third-party seller, the invoice must be issued by that seller. If the marketplace issues an invoice in its own name for a third-party sale, it is invalid for ITC.

Is it legal for a seller to charge GST without being registered?

No. A seller must be registered under GST to charge GST on an invoice. If an unregistered seller charges GST, it is illegal, and you cannot claim ITC. You can report such sellers to the GST department.

What is the difference between IGST and CGST+SGST on my invoice?

If the seller and the delivery location are in the same state, the invoice will show CGST and SGST (equal rates). If they are in different states, it will show IGST (the sum of the two). The total tax rate is the same in both cases, but the type of tax matters for ITC claims and state-wise reporting.
