FAQs

In this blog, we'll go through the step-by-step registration process for GST & TCS as an online marketplace seller in India, from the documents you need to how the tax system works.

Key Takeaways

You need to register for GST even if your annual sales are only ₹1,000.

Your GST registration is linked directly to your Permanent Account Number (PAN).

The 1% tax the marketplace cuts is not a loss because you get it back as a balance to pay your future taxes.

You must file your returns every month, as missing a deadline results in daily penalties.

Using a service like Gonukkad helps you maintain a high ROAS on Myntra, Flipkart, and Amazon.

Is GST Registration Really Necessary for Small Online Shops

Under the law, any person supplying goods through an e-commerce operator must have GST & TCS Registrations for Online Marketplace Sellers.

Unlike a local kirana store, which only needs to register for GST after crossing a high turnover threshold, an online seller is considered an "Inter-state" supplier from day one.

Since you are selling to customers across India, the government wants to track every transaction to ensure fair tax collection.

Understanding TCS Under GST for E-commerce Sellers

TCS stands for Tax Collected at Source. When you sell a product for ₹2,000 on a marketplace, the platform is required by law to deduct 1% (₹20) before sending the rest of the money to your bank account.

It is called TCS Under GST for E-commerce Sellers.

The marketplace pays 1% to the government on your behalf.

Every month, you can claim 1% TCS back into your GST Electronic Cash Ledger to pay your own taxes.

Understanding TCS Compliance for E-commerce Sellers in India

Once you start selling, you must stay compliant. It means following the rules every month so the government doesn't freeze your account. TCS Compliance for E-commerce Sellers in India involves comparing your sales reports with the marketplace's records.

If you sell ₹1,00,000 worth of goods in a month:

The marketplace collects ₹1,000 as TCS.

You must file your returns to accept this amount.

If you forget to file, you lose that ₹1,000 and have to pay extra penalties.

GST Filing for Online Marketplace Sellers

As an online seller, you will generally deal with two main filings:

GSTR-1: It is where you tell the government who you sold to and for how much. (Due by the 11th of every month).

GSTR-3B: It is your final monthly summary for paying any remaining tax. (Due by the 20th of every month).

Conclusion

Getting your GST & TCS Registration for Online Marketplace Sellers is the first official step to becoming a successful digital seller. While the 1% TCS and monthly filings might seem like a lot of work, they are simply part of the modern way of doing business in India. By staying compliant, you build a healthy business that can grow without legal penalties.
