GST Tax Planning for E-commerce
How we helped a multi-state e-commerce business optimize their GST structure, reduce tax liability by 22%, and achieve full compliance across multiple jurisdictions
Client Overview
A rapidly growing e-commerce company specializing in consumer electronics with operations across 18 states in India.
Our client had experienced exponential growth over the past two years, expanding from a regional player into a nationwide e-commerce platform. With annual revenue exceeding ₹85 crore, the company was facing increasingly complex GST challenges across multiple jurisdictions. Their product catalog included over 5,000 SKUs across various electronics categories, with warehouses in 6 different states and customers throughout India.

Key Challenges
-
Complex Multi-State Compliance
Managing GST registrations and filings across 18 states
-
Input Tax Credit Issues
Struggling to optimize ITC utilization across operations
-
Inefficient Supply Chain Structure
Tax-inefficient movement of goods between warehouses
-
Compliance Penalties
Facing significant penalties for filing discrepancies
The Challenge
The client's rapid expansion had created a complex GST compliance landscape with significant inefficiencies and risk exposure.
The e-commerce company had grown so quickly that their tax infrastructure couldn't keep pace with their operational expansion. This created several critical problems:
- The company was maintaining separate GST registrations in all 18 states where they had customers, creating an unnecessary compliance burden
- Their supply chain was designed without GST considerations, resulting in cascading taxes and suboptimal warehouse locations
- Input Tax Credit (ITC) was not being properly tracked or utilized, leading to approximately ₹1.8 crore in unclaimed credits
- There were significant gaps in their e-invoicing and e-way bill processes, resulting in compliance penalties exceeding ₹35 lakh in the previous fiscal year
- Product classification was inconsistent, with some items being charged at incorrect GST rates
- The finance team was spending over 250 hours monthly on GST compliance activities, taking resources away from strategic financial management
Additionally, the company was planning expansion into 5 more states and considering international markets, which would further complicate their tax structure. They needed a comprehensive GST strategy that would support their growth while ensuring compliance and optimizing their tax position.

Working with Sompalli & Co transformed our approach to GST. Before their intervention, we were essentially throwing money away through inefficient tax structures and missed input credits. Their systematic approach not only recovered significant tax amounts but created a sustainable framework that continues to deliver value as we expand. The most impressive part was how they integrated GST optimization with our business strategy, turning what was once a compliance burden into a competitive advantage.
