GST and TCS for marketplace sellers: registration and reconciliation

The two blanket rules repeated in many seller guides—“every marketplace seller needs GST registration” and “TCS is 1%”—are not current. Registration depends on the supplier, turnover, geography and fulfilment model, while the combined GST TCS rate has been 0.5% since July 2024.

This guide is general operational information, not tax advice. Confirm the legal entity, products, states, stock locations and fulfilment model with a qualified GST professional before onboarding, moving inventory or changing a filing position.

What changed in October 2026?

On 8 October 2026, the GST Council recommended inserting Rule 14B into the CGST Rules. The proposed mechanism would let qualifying small goods suppliers register in a State or Union territory where they have no physical presence by declaring an e-commerce operator's warehouse there as their principal place of business.

The official 57th GST Council meeting release describes three important boundaries:

• it is a recommendation for a simplified registration mechanism, not an extension of the unregistered-seller exemption;
• it is intended for supplies through e-commerce operators in States or Union territories where the seller lacks physical presence; and
• it is intended for sellers passing on input tax credit of not more than ₹2.5 lakh per month, excluding stock transfers between distinct persons.

The release says registration would be granted automatically by the system subject to conditions. It does not, by itself, supply the final operative rule, its commencement date, the complete conditions or the marketplace workflow.

What sellers should do now

Treat the 8 October announcement as a recommended future route until the necessary rule or notification takes effect and the GST portal and chosen marketplace support it. Do not move stock into another State, alter invoice mapping or cancel an existing registration because of a press report.

Before using the proposed route, retain the final notification, effective date, portal acknowledgement, operator consent or warehouse document, and professional advice supporting the chosen registration. This distinction matters: a Council recommendation can describe the intended policy without yet changing the operative compliance position.

Do marketplace sellers always need GST registration?

No. Notification 34/2023-Central Tax, dated 31 July 2023, waived mandatory registration under section 24(ix) for certain people supplying goods through e-commerce operators. It took effect on 1 October 2023 and remains a conditional exemption—not a general permission to sell anywhere without a GST registration.

A goods supplier using the exemption must, among other conditions:

• remain below the applicable registration threshold in both the preceding and current financial year;
• make no inter-State supply of goods;
• supply through e-commerce operators in only one State or Union territory;
• hold a PAN;
• declare the principal place of business and obtain the prescribed enrolment number on the common portal before supplying; and
• stop using that enrolment number when a later GST registration takes effect.

Failing any condition can change the answer. A seller planning inter-State customer supplies, dispatching from more than one State, crossing the applicable threshold or already registered should not assume the exemption applies. Marketplace onboarding and category controls may also be narrower than the tax-law exemption, so confirm the current platform workflow separately.

Registration exemption and simplified registration are different

The enacted 2023 exemption and the recommended 2026 mechanism solve different problems:

• Notification 34/2023: an eligible supplier remains unregistered and makes only intra-State goods supplies through operators in one State or Union territory.
• Recommended Rule 14B: a qualifying small supplier would obtain a registration for platform sales in another State or Union territory despite having no physical premises there, using an operator warehouse as the principal place of business.

Do not merge these routes in a checklist. Record which legal route is being used for each State and the evidence supporting it.

Use a stock-movement decision gate

Marketplace fulfilment can make a registration question look like a logistics setting. In reality, enabling a fulfilment centre in another State can change stock location, registration, invoicing and return-reporting requirements.

Before approving a new dispatch State or moving stock, document:

1. the PAN and legal entity that owns the inventory;
2. current GST registrations and enrolment numbers;
3. expected aggregate turnover in the preceding and current financial year;
4. each State from which stock may be dispatched or returned;
5. whether customer supplies or stock transfers can cross State borders;
6. the marketplace's proposed fulfilment and invoicing flow; and
7. the operative notification and professional review supporting the structure.

Pause the stock move if the registration route, principal place of business, invoice GSTIN or effective date is unresolved. A reversible account setting is not evidence that the tax treatment is correct.

What is GST TCS on marketplace sales?

Under section 52, an e-commerce operator that collects customer consideration may have to collect tax at source on the net value of taxable supplies made through it by other suppliers. This is separate from marketplace commission, shipping and other commercial fees.

Net taxable value for the period reduces taxable supplies by taxable returns during that period. The GST Council's official TCS FAQ explains that a negative amount is not carried forward when returns exceed supplies for a supplier in a tax period.

GST TCS is also not income-tax TDS. Keep separate ledger columns for GST TCS, any income-tax deduction, GST charged on marketplace service invoices and commercial fees. Combining them makes settlement and tax reconciliation harder.

What is the current TCS rate?

The combined GST TCS rate is 0.5% from 10 July 2024:

• intra-State taxable supplies: 0.25% CGST plus 0.25% SGST or UTGST; or
• inter-State taxable supplies: 0.5% IGST.

The Ministry of Finance recorded the change in its 2024 year-end release, citing the three amending notifications dated 10 July 2024. The GST portal's current GSTR-8 FAQ separately confirms that the portal validation changed from 1% before the July 2024 tax period to the revised range from July 2024 onward.

If a current settlement appears to use 1%, first check the supply date, tax period, tax heads and whether the line is GST TCS rather than another deduction. Preserve the source report and investigate the variance instead of overwriting it to force the expected result.

Illustrative TCS calculation

Suppose a registered seller has ₹120,000 of taxable supplies and ₹20,000 of taxable returns through one operator in the same tax period. The illustrative net taxable value is ₹100,000, so combined TCS at 0.5% is ₹500.

For intra-State supplies, that illustrative ₹500 would be split as ₹250 CGST and ₹250 SGST or UTGST. For inter-State supplies, it would be ₹500 IGST. This simplified example excludes facts that can change the treatment and is not a filing calculation.

Where does marketplace TCS appear?

The operator reports supplies, returns and TCS in Form GSTR-8. The GST portal's Electronic Cash Ledger FAQ states that accepted TDS and TCS credits reflect in the electronic cash ledger and can be used to discharge tax liabilities.

TCS is therefore not input tax credit and should not be booked as a marketplace fee. It is a cash-ledger amount linked to the operator's reporting. GST charged on eligible marketplace service invoices follows a separate invoice and input-tax-credit review.

Reconcile GSTR-8 before accepting the credit

The current GST portal GSTR-8 manual says operator-reported TCS details can be accepted or rejected by the supplier. It also states that an operator cannot amend details once the supplier has accepted them, while rejected records remain available for operator action.

That makes acceptance a control point, not a routine click. Use one reconciliation line per operator, supplier GSTIN, tax head and tax period:

1. Preserve the marketplace tax, return and settlement exports for the period.
2. Confirm that the exports cover the full period, legal entity and GSTIN.
3. Calculate taxable supplies and same-period taxable returns from transaction-level data.
4. Separate intra-State and inter-State transactions and calculate expected TCS using the applicable effective date.
5. Compare expected TCS with the operator report by CGST, SGST or UTGST, and IGST.
6. Compare the operator report with the GSTR-8/TCS record before accepting or rejecting it.
7. After acceptance, confirm that the amount appears under the correct heads in the electronic cash ledger.
8. Record every difference by reason: timing, return period, GSTIN, place of supply, taxable value, duplicate, omission or unidentified.
9. Keep the source export, GSTR-8 detail, acceptance or rejection evidence, cash-ledger extract and resolution reference together.

Do not mark a difference resolved merely because the bank payout matches. A settlement can net commercial fees, refunds, reimbursements and multiple tax deductions while the portal credit remains wrong.

Common GST and TCS mistakes

Acting on a recommendation as if it were operative law

Record the final rule or notification and effective date before changing registration or stock placement. The October 2026 announcement describes a recommended mechanism; it is not a substitute for the operative text.

Assuming low turnover is the only exemption test

The enacted exemption also restricts inter-State goods supplies and the State footprint. Test every condition against the proposed fulfilment model.

Looking for TCS in the input-tax-credit ledger

Accepted GST TCS goes to the electronic cash ledger. GST on eligible marketplace invoices follows separate input-tax-credit rules.

Accepting GSTR-8 data before matching it

Acceptance can close the operator's amendment route for that record. Preserve the displayed data, reconcile it and document the reason before accepting or rejecting.

Mixing legal entities or GSTINs

Seller-account master data, invoices, settlement reports and portal records must point to the intended entity and GSTIN. Reconcile each registration separately.

A clean onboarding and monthly-close handoff

Before the first listing or stock move, prepare a short handoff containing:

• legal entity, PAN and registration or enrolment status;
• the notification or rule relied upon and its effective date;
• principal and additional places of business;
• permitted dispatch and customer-supply geography;
• marketplace account-to-GSTIN and warehouse mapping;
• product tax classifications reviewed by the appropriate adviser;
• owners for marketplace exports, GSTR-8 review and cash-ledger reconciliation; and
• a monthly close date with an unresolved-variance log.

This makes the registration decision auditable and turns TCS from an unexplained payout deduction into a traceable ledger movement. Recheck the official sources whenever the fulfilment model, State footprint, portal workflow or law changes.
