Selling Online? Here’s What GST Rules in 2025 Mean for E-Commerce Businesses

NEW DELHI — India’s e-commerce sector is experiencing explosive growth. With over 1.2 crore active sellers across platforms like Amazon India, Flipkart, and Meesho, and the industry projected to reach $160 billion by 2028, online selling has become one of the most significant economic opportunities for small businesses, home entrepreneurs, and MSMEs across Delhi NCR. Yet behind every successful online store lies a compliance landscape that trips up thousands of sellers every year — leading to blocked payments, cancelled GSTINs, ITC mismatches, and costly notices from tax authorities. B M C & Associates, a leading GST and tax advisory firm in Delhi NCR with 14+ years of experience, breaks down what changed in 2025 for e-commerce GST compliance and what every online seller — from a Meesho reseller to an Amazon FBA merchant — must do right now to stay compliant and protect their business.
The E-Commerce GST Landscape in 2025: Why Compliance Has Never Been More Critical
The Goods and Services Tax framework for e-commerce sellers operates very differently from that for traditional brick-and-mortar businesses. Three critical distinctions define the compliance challenge for online sellers in India:
📌  3 Rules That Make E-Commerce GST Unique:
•        GST registration is MANDATORY for all e-commerce sellers regardless of turnover — the standard ₹20 lakh threshold does NOT apply (Section 24, CGST Act)
•        E-Commerce Operators (ECOs) like Amazon, Flipkart, and Meesho must deduct TCS (Tax Collected at Source) at 0.5% on every seller transaction under Section 52 of the CGST Act
•        Platforms also deduct Income Tax TDS at 0.1% under Section 194-O — creating a dual deduction regime that sellers must track and reconcile separately
 
“The most dangerous assumption we see among Delhi NCR’s online sellers is that because their turnover is below ₹20 lakh, they don’t need GST registration. For e-commerce, this is completely wrong. The moment you list a product on Amazon, Flipkart, or Meesho, GST registration becomes mandatory from day one — with no exceptions.”
— CA Bipin Kumar Jha, Partner, B M C & Associates
What Specifically Changed for E-Commerce GST Compliance in 2025
1. TCS Rate Reduced to 0.5% — But Reconciliation Scrutiny Has Intensified
From July 10, 2024, the GST TCS rate was reduced from 1% to 0.5% of the net taxable value of supplies made through e-commerce platforms. For inter-state sales, this means 0.5% collected as IGST. For intra-state sales, it splits as 0.25% CGST and 0.25% SGST.
While the rate reduction is a relief, the government simultaneously tightened reconciliation requirements. From April 2025, GSTR-8 filings by platforms must include more granular state-wise and product-category data. The GST system now auto-matches TCS deductions reported in GSTR-8 against what sellers claim in GSTR-3B — any mismatch triggers automated notices without human intervention.
⚠️  What This Means for Sellers in Practice:
•        Your TCS credit appears in GSTR-2B (auto-generated on the 14th of each month) — verify this against your marketplace settlement reports before claiming in GSTR-3B
•        If your GSTIN on the marketplace is incorrect or mismatched, your TCS credit may NOT appear in GSTR-2B — causing a compliance gap
•        Sellers on multiple platforms (Amazon + Flipkart + Meesho) must reconcile TCS from each platform separately, as each files its own GSTR-8
 
2. Income Tax TDS Under Section 194-O Now at 0.1% — Non-PAN Sellers Pay 5%
Separate from GST TCS, e-commerce platforms are also required to deduct Income Tax TDS under Section 194-O of the Income Tax Act. From October 1, 2024, this rate was reduced to 0.1% of gross sales (previously 1%) for sellers who have furnished their PAN or Aadhaar.
However, sellers who have NOT provided their PAN or Aadhaar to the marketplace face a steep 5% TDS deduction from the first rupee — a severe cash flow penalty for non-compliance. This TDS is reflected in Form 26AS and the Annual Information Statement (AIS) and must be claimed as credit while filing the annual Income Tax Return.
❌  Common TDS Mistake Costing Sellers Lakhs:
•        Not linking PAN with marketplace account — results in 5% TDS instead of 0.1%
•        Forgetting to claim 194-O TDS credit in annual ITR — this money is permanently lost if not claimed
•        Treating TDS as final tax — it is an advance payment, actual liability may be lower and a refund may be due
•        Not cross-checking Form 26AS against marketplace settlement statements to ensure all TDS is captured
 
3. GST on Quick Commerce, Delivery Fees and Cloud Kitchens — New 2025 Rules
Budget 2025 and subsequent GST Council decisions introduced new compliance requirements for the booming quick commerce sector (10–30 minute delivery platforms like Blinkit, Zepto, Swiggy Instamart):
•        Delivery charges levied by quick commerce platforms are now subject to 18% GST, regardless of whether the platform or the customer bears the cost
•        Cloud kitchens and dark stores operating in multiple states must obtain separate GST registrations in each state where they have operations — a single GSTIN is no longer sufficient
•        Platform commission fees, promotional charges, and listing fees may now attract Reverse Charge Mechanism (RCM) liability in certain scenarios, requiring sellers to self-assess and pay GST directly
 
4. Stricter Place of Supply Rules and E-Way Bill Validation
The determination of Place of Supply (PoS) has become stricter in 2025. Online sellers must correctly identify whether each transaction is intra-state (CGST + SGST applies) or inter-state (IGST applies) based on the buyer’s location — not the seller’s location. Errors in PoS classification are one of the most common triggers for GST audits.
Additionally, e-Way Bill validation has been strengthened with tighter digital checks. Sellers dispatching goods above ₹50,000 in value across state lines must ensure e-Way Bills are generated before dispatch and are correctly linked to the sale invoice.
5. Multi-Factor Authentication (MFA) Mandatory on GST Portal
From 2025, the GST portal has implemented phased Multi-Factor Authentication (MFA) for all taxpayers. Sellers and their accountants must now verify logins via an OTP sent to the registered mobile number. Any GSTR filing without MFA-verified access is considered invalid. For sellers who have their CA or accountant file on their behalf, this means both parties must coordinate OTP verification for every filing cycle.
7 GST Compliance Mistakes E-Commerce Sellers in Delhi Must Stop Making
B M C & Associates’ GST advisory team has identified the seven most costly errors made by online sellers across Delhi NCR, based on their compliance work with sellers on all major platforms:
MISTAKE 1: Selling Without GST Registration — or With Expired Registration
Operating on any e-commerce platform without a valid GSTIN is illegal under GST law, regardless of your turnover. Platforms like Amazon and Flipkart are legally required to deactivate sellers with invalid or expired GSTINs. Beyond platform suspension, penalty under Section 122 of the CGST Act can be ₹10,000 or the amount of tax evaded, whichever is higher.
✅ Fix: Register for GST before listing your first product. Registration via the GST portal takes 3–7 working days with Aadhaar-based authentication. BMC can complete registration in 48 hours.
MISTAKE 2: Not Reconciling TCS Credits Before Filing GSTR-3B
Many sellers claim TCS credits in GSTR-3B without first verifying that those credits actually appear in GSTR-2B (auto-populated from platforms’ GSTR-8 filings). If there is a mismatch — due to incorrect GSTIN on the platform, timing differences, or platform filing errors — the credit claim is invalid and creates a recoverable demand.
✅ Fix: Every month: download GSTR-2B on the 14th, reconcile against each platform’s settlement report, then file GSTR-3B on the 20th. Only claim TCS credits that appear in GSTR-2B.
MISTAKE 3: Incorrect HSN/SAC Code Classification Leading to Wrong Tax Rates
Every product must be classified under the correct Harmonised System of Nomenclature (HSN) code, and the corresponding GST rate must be applied on each invoice. Many sellers either use a generic code or apply incorrect rates, leading to short-payment of GST (which attracts interest and penalty) or excess GST collection from buyers (which must be refunded).
✅ Fix: For turnover above ₹5 crore, HSN codes at 6-digit level are mandatory. For ₹1.5–5 crore, 4-digit codes apply. Below ₹1.5 crore, 4-digit codes are recommended. Use the CBIC HSN code finder or consult BMC’s GST team for correct classification.
MISTAKE 4: Losing ITC on Marketplace Commissions, Logistics and Advertising Fees
Every fee that platforms charge sellers — commission (18% GST), FBA fulfilment fees, sponsored ads, storage fees, return processing fees — comes with a GST invoice. Sellers who do not claim Input Tax Credit on these expenses are paying significantly more tax than they legally need to.
✅ Fix: Download all platform fee invoices each month from your seller account dashboard. Ensure they appear in GSTR-2B and claim ITC in GSTR-3B. Note: ITC must be reversed for returns where goods come back unsold.
MISTAKE 5: Multi-State Operations Without State-Wise GSTIN Registration
Sellers who store inventory in Amazon FBA warehouses or Flipkart fulfilment centres in multiple states are legally required to register for GST in each state where they have stock. Operating with a single GSTIN while storing goods in multiple states constitutes non-compliance and can attract significant penalties under GST law.
✅ Fix: Check your FBA/fulfilment inventory report to identify which states your stock is stored in. Register for GST in each such state as an 'Additional Place of Business'. BMC handles multi-state GST registrations routinely.
MISTAKE 6: Filing GSTR-1 and GSTR-3B With Mismatched Turnover Figures
The turnover reported in GSTR-1 (outward supply details) must match the turnover in GSTR-3B (tax payment return) and must also align with the data reported by platforms in their GSTR-8. With auto-matching now active on the GST system, even minor discrepancies — caused by returns, cancelled orders, or commission netting — trigger automated scrutiny notices.
✅ Fix: Reconcile your marketplace sales report with GSTR-1 data before every filing. Account for returns, cancellations, and credit notes separately. BMC provides monthly reconciliation services specifically designed for multi-platform sellers.
MISTAKE 7: Missing the GSTR-9 Annual Return — Or Filing an Inaccurate One
Sellers with annual turnover above ₹2 crore must file GSTR-9 (annual return) by December 31 each year. Those above ₹5 crore also need GSTR-9C (self-certified reconciliation). Many high-volume online sellers cross these thresholds without realising it, and either miss the filing or submit inaccurate figures — attracting a late fee of ₹200 per day and potential audit scrutiny.
✅ Fix: Track your cumulative turnover across all platforms monthly. Once you approach ₹2 crore, engage a CA to prepare GSTR-9 in advance. BMC prepares annual returns for e-commerce sellers with multi-platform reconciliation built in.
“E-commerce sellers in Delhi NCR are sitting on significant ITC they are not claiming. Between platform commissions, logistics fees, advertising costs, and packaging materials, most sellers are eligible for substantial input tax credit that directly reduces their GST outgo. Our job is to make sure not a single rupee of legitimate credit is left unclaimed.”
