Selling through digital marketplaces like Amazon, Meesho, or Flipkart offers wide market access, but multi-channel reporting creates distinct portal challenges. Small businesses handling both regular GST registrations and composition scheme options often face confusion regarding TCS deductions, inward input tax credit restrictions, and monthly return declarations. If you manage sales on ecommerce platforms, knowing the exact statutory mechanics keeps your working capital liquid.
Understanding the composition scheme cutover for online sellers
Under the provisions of the Section 10, CGST Act, small traders supplying goods intra-State through ecommerce operators can operate under the simplified composition levy. However, opting into or switching away from composition requires strict adherence to statutory credit rules.
When an existing regular taxpayer opts into composition, they must reverse all unutilised input tax credit on inputs held in stock and capital goods using Form GST ITC-03, as mandated by the Rule 44 of CGST Rules. Conversely, when a seller crosses the composition threshold and switches back to the regular scheme, they become eligible to claim input credit on inventory held in stock by filing Form GST ITC-01 within 30 days under the Rule 40 of CGST Rules.
Common mistake: Attempting to claim input tax credit on platform commissions, logistics fees, or inward stock while paying tax under Section 10. Under Section 17(5)(e) of the CGST Act, ITC on goods or services on which tax has been paid under Section 10 is strictly blocked. In addition, composition sellers do not file Form GSTR-1; they file quarterly statements in Form GST CMP-08.
How Section 52 TCS credits reflect in your electronic cash ledger
Every ecommerce operator collecting consideration for taxable supplies made through its marketplace must collect Tax Collection at Source (TCS) under Section 52 of the CGST Act. The platform operator reports these deductions by filing Form GSTR-8 on or before the 10th of the succeeding month, pursuant to the Rule 67(1) of CGST Rules.
Once the operator files Form GSTR-8, the collected tax is made available electronically to the seller on the GST common portal. Per the Rule 87(9) of CGST Rules, any amount collected under Section 52 and accepted by the seller is credited directly to their electronic cash ledger, which can then be utilised to discharge output GST liability in Form GSTR-3B.
Portal workflow to accept Section 52 TCS credits
- Navigate to TDS and TCS dashboard: Log in to the GST portal and go to Services → Returns → TDS and TCS credit received.
- Select the tax period: Choose the return period matching the platform deduction (for example, October 2026 for credits filed by 10 November 2026).
- Review marketplace deductions: Open the TCS details tile to review the net taxable value and tax collected reported under each operator GSTIN.
- Accept and file: Select the records, click Accept, and file the statement using DSC or EVC. The accepted amount updates your electronic cash ledger immediately.
Reporting ecommerce supplies in Form GSTR-1 Table 14
Regular taxpayers selling through marketplace platforms must report their outward supplies accurately across two distinct sections of Form GSTR-1. While state-level consumer sales appear in Table 7 (B2C Others) or Table 5 (B2C Large), the supplies facilitated through platforms must also be reported in Table 14.
According to the official GSTN GSTR-1 User Manual, Table 14 contains two separate tabs: (a) Liable to collect tax u/s 52 (TCS), and (b) Liable to pay tax u/s 9(5). Crucially, values entered under the Section 52 TCS tab of Table 14 are informational and are not added again to the total outward liability in the consolidated summary table, eliminating double taxation.
Worked example: reconciling monthly sales and TCS cash credit
Consider M/s Apex Retail, a proprietary seller registered in Maharashtra supplying lifestyle goods across India through Amazon and Flipkart. During October 2026, the business records total marketplace sales of ₹5,00,000 subject to 18% GST (9% CGST + 9% SGST).
| Description | Taxable value | CGST | SGST | Total |
|---|---|---|---|---|
| Gross marketplace sales | ₹5,50,000 | ₹49,500 | ₹49,500 | ₹6,49,000 |
| Customer sales returns | ₹50,000 | ₹4,500 | ₹4,500 | ₹59,000 |
| Net supplies under Section 52 | ₹5,00,000 | ₹45,000 | ₹45,000 | ₹5,90,000 |
| Section 52 TCS collected (0.5% + 0.5%) | ₹5,00,000 | ₹2,500 | ₹2,500 | ₹5,000 |
Here is how the numbers flow through the return filing cycle:
The marketplace operator collects TCS of ₹2,500 CGST and ₹2,500 SGST on net sales of ₹5,00,000. When Apex Retail accepts the TCS credit on the portal, ₹5,000 enters their electronic cash ledger. In Form GSTR-3B, the gross tax liability of ₹90,000 (₹45,000 CGST + ₹45,000 SGST) is offset using available input tax credit from GSTR-2B, with the remaining cash portion paid using this TCS cash balance.

E-way bill restrictions under Rule 138E
Timely filing of return statements is vital for continuous dispatches. Under the Rule 138E of CGST Rules, no person, including an ecommerce operator or courier agency, is permitted to generate Part A of Form GST EWB-01 if the seller has defaulted on return filings.
Specifically, Rule 138E blocks e-way bill generation if a composition taxpayer fails to furnish Form GST CMP-08 for two consecutive quarters, or if a regular taxpayer fails to furnish GSTR-3B or GSTR-1 for two consecutive tax periods. Staying current with return deadlines ensures your platform listings and carrier pickups remain active.
Frequently asked questions
Can an ecommerce seller opt into the composition scheme under Section 10?
Yes, eligible micro-sellers supplying intra-State goods through an ecommerce operator can opt for composition levy, but they cannot make inter-State outward supplies and cannot claim input tax credit.
Where does Section 52 TCS appear on the GST portal for ecommerce sellers?
Ecommerce operators file TCS returns in Form GSTR-8 by the 10th of the month. The collected amount appears under Services > Returns > TDS and TCS credit received on the portal and credits directly into the seller electronic cash ledger upon acceptance.
Does reporting supplies in GSTR-1 Table 14 increase total tax liability in GSTR-3B?
No, per the GSTN GSTR-1 user manual, values entered in Table 14 under the Section 52 TCS tab are informational and are not included in the computation of total outward tax liability in the summary table.
