How to Get GST Number for Online Selling: Quick Guide for Sellers

If you’ve just started selling online whether on Amazon, Flipkart, Meesho or your own store, you’ve probably wondered, “Do I need a GST number to sell online?”

As you are selling online, the answer is yes, every online seller in India should have a GST number. It is not complicated as it sounds. In this quick and easy guide by Swipe Billing App, we’ll explain what GST is, why you need it and how you can get your GST number step by step, without any confusion.

What Is GST and Why Does It Matter?

Goods and Services Tax(GST) is basically a tax that you pay when selling goods or services in India. Before GST, there were different taxes. It was very difficult to keep track of everything. Now, everything is under one system called GST.

If your annual sales are above ₹20 lakh (₹10 lakh in some states), you must register for GST. But even if your sales are less, you still need GST if you’re selling online.

Why Do Online Sellers Need GST?

•Online marketplaces like Amazon, Flipkart and Meesho make GST mandatory.

•Without GST, you can’t list products on most platforms.

•It allows you to claim Input Tax Credit (ITC). It means you can reduce the tax you pay.

•It makes your business look professional and trustworthy.
