GST Registration for an E-Commerce Business

GST Registration for an E-Commerce Business by Sigma Solutions

Introduction

In 2024, an ambitious e-commerce entrepreneur based in North East India experienced rapid growth in online sales. As the business began receiving orders from across the country via platforms like Amazon, Flipkart, and its own Shopify-based website, the founder realized that operating without Goods and Services Tax (GST) registration was limiting business expansion.

The entrepreneur’s annual turnover had crossed ₹22 lakh, crossing the mandatory GST registration threshold of ₹20 lakh (for service providers) and ₹40 lakh (for goods suppliers). Without GST registration, the business:

Risked penalties and legal notices
Could not claim input tax credit (ITC)
Faced restrictions on interstate sales

The founder turned to Sigma Solutions for expert assistance in navigating the complex registration and compliance landscape.

Challenges Faced by the Founders

Although the e-commerce platform was growing fast, the founder faced multiple tax and compliance-related roadblocks:

Lack of Clarity on GST Applicability

Unsure if GST registration was mandatory for online sellers, especially since the business was based in Arunachal Pradesh.
No understanding of CGST, SGST, IGST, or composite vs. regular schemes.

Documentation Hurdles

Struggled to compile the necessary documents:
- Business PAN
- Address proof
- Bank account verification
- Photographs and Aadhaar authentication

Input Tax Credit (ITC) Confusion

Did not know:
- How to claim ITC on raw materials, packaging, shipping, and digital tools
- Which items were ineligible for credit
- How to maintain supplier compliance to avoid ITC mismatches

GST Compliance & Filing Issues

Unfamiliar with GST return types:
- GSTR-1 for outward supplies
- GSTR-3B for summary returns
- GSTR-9 for annual return
No system for return deadlines or payment tracking

E-Commerce Taxation and TCS Deductions

Selling on platforms like Flipkart and Amazon, but unaware of:
- Tax Collected at Source (TCS) at 1% under Section 52 of the CGST Act
- How to reconcile TCS deductions with GST returns
- Impact of TCS on cash flow and compliance
