GST on E-Commerce and Digital Services in India — OIDAR, Marketplace and SaaS Compliance
The growth of cross-border digital commerce has created a distinct and rapidly evolving GST compliance landscape in India. Foreign companies providing digital services, SaaS platforms, streaming content, online marketplaces, and database access services to Indian consumers and businesses face GST obligations that are fundamentally different from those applying to conventional goods and services trade. The rules are specific, the compliance thresholds are low, and the penalties for non-compliance are significant — yet the majority of foreign digital service providers operating in India remain unregistered and non-compliant.
At A2 Consultants, we provide specialist GST advisory and compliance services for foreign companies providing digital services into India — covering OIDAR registration and returns, marketplace operator compliance, SaaS and subscription service GST structuring, e-commerce operator TCS obligations, and the rapidly evolving digital economy GST framework that continues to expand in scope with each Finance Act amendment.
OIDAR Services — Online Information Database Access and Retrieval
What Are OIDAR Services
OIDAR services are a specific category of digital services defined under the IGST Act as services delivered over the internet or electronic network and whose supply is essentially automated, involving minimal human intervention, and impossible to ensure in the absence of information technology. The definition captures a broad range of digital services including cloud computing services, software as a service, platform as a service, infrastructure as a service, online gaming, streaming music and video, digital content downloads, online advertising services, distance learning through automated online platforms, database access services, online marketplaces, and web hosting services.
The defining characteristic of OIDAR services is automation — services that are delivered automatically through technology without meaningful human involvement at the point of delivery. This distinguishes OIDAR services from professional advisory or consulting services delivered electronically, which are not OIDAR and are subject to standard import of services reverse charge rules instead.
Who Must Register for OIDAR GST in India
A foreign supplier of OIDAR services to recipients located in India is required to register for GST in India as a Non-Resident Online Service Provider — regardless of whether the Indian recipient is a registered business or an individual consumer. Unlike the reverse charge mechanism that applies to B2B import of services, OIDAR services supplied to unregistered Indian recipients — individual consumers, small businesses below the GST threshold, and exempt entities — are taxable in the hands of the foreign OIDAR provider directly. There is no threshold for OIDAR registration — even a single taxable supply of OIDAR services to an Indian recipient creates a registration obligation.
OIDAR Registration Process
Foreign OIDAR providers register for GST in India as Non-Resident Taxable Persons through a simplified online registration process on the GST portal. Registration requires appointment of an authorised representative in India, a valid overseas tax identification number or equivalent, details of the digital services being provided, and a declaration of the estimated value of supplies to Indian recipients. Unlike domestic GST registration, OIDAR registration does not require an Indian PAN — a significant simplification for foreign providers without an India corporate presence.
We manage the complete OIDAR registration process — including authorised representative appointment, GST portal registration, GSTIN issuance, and initial compliance setup.
OIDAR GST Returns
Registered OIDAR providers must file quarterly GST returns reporting the value of OIDAR supplies made to Indian recipients during the quarter and paying the applicable IGST. The return is simplified compared to domestic GST returns — OIDAR providers file a consolidated quarterly statement rather than the monthly GSTR-1 and GSTR-3B cycle applicable to domestic registrants. However the return must accurately capture all supplies made to Indian recipients — both B2B supplies to registered businesses and B2C supplies to unregistered consumers — and payment must be made in Indian rupees through the GST portal.
B2B vs B2C OIDAR Supplies — Critical Distinction
The GST treatment of OIDAR services differs fundamentally depending on whether the Indian recipient is a registered GST taxpayer or an unregistered consumer.
For B2B supplies — where the Indian recipient is a GST-registered business — the reverse charge mechanism applies. The Indian recipient pays GST on the OIDAR supply received and the foreign OIDAR provider is not required to charge GST on the B2B invoice. However the foreign provider must still track B2B supplies separately in its OIDAR return to avoid double taxation.
For B2C supplies — where the Indian recipient is an individual consumer, unregistered business, or exempt entity — the foreign OIDAR provider is directly liable to collect and remit IGST. There is no reverse charge available for B2C OIDAR supplies. The foreign provider must charge 18% IGST on all B2C supplies to Indian recipients, collect it from the customer, and remit it to the Indian government through the quarterly OIDAR return.
This B2B versus B2C distinction is operationally significant for foreign OIDAR providers — it requires systems to identify the GST registration status of Indian customers at the point of transaction, apply the correct tax treatment, and maintain documentation to support the classification in the event of a GST audit.
SaaS and Subscription Services — GST Structuring
Software as a Service delivered to Indian recipients is OIDAR by definition — it is automated, technology-delivered, and requires minimal human intervention at the point of supply. Foreign SaaS companies providing subscription access to software platforms, productivity tools, CRM systems, ERP cloud solutions, design tools, and analytics platforms to Indian users are providing OIDAR services and are subject to the GST registration and compliance obligations described above.
Per-Seat Subscription Pricing and GST
For SaaS providers with per-seat or per-user pricing, GST applies on the total subscription value charged to each Indian customer. Where a single enterprise customer in India has multiple users across multiple Indian states, the place of supply is the Indian customer's registered address — and a single B2B invoice to the registered GST business triggers reverse charge in the hands of the Indian customer rather than GST collection by the foreign SaaS provider.
Freemium and Trial Period GST Treatment
Free tiers and trial periods for SaaS products do not attract GST as no consideration is received. The transition from free to paid creates the GST obligation. However where a free tier is provided alongside paid features — with the paid features being OIDAR services — only the paid component attracts GST. We advise on SaaS product structuring to ensure GST applies correctly at the right tier boundary.
Annual vs Monthly Billing and Time of Supply
GST becomes payable on the earlier of the date of invoice or the date of payment for subscription services. Annual subscriptions billed upfront create a full-year GST liability at the point of billing — not ratably over the subscription period. We advise on billing cycle structuring and GST payment timing to optimise cash flow for foreign SaaS providers with large Indian customer bases.
E-Commerce Marketplace Operators — TCS Obligations
Who Is an E-Commerce Operator Under GST
An e-commerce operator is any person who owns, operates, or manages a digital or electronic facility or platform for the supply of goods or services. Foreign companies operating online marketplaces that facilitate supplies by Indian sellers to Indian buyers — or by Indian service providers to Indian consumers — are e-commerce operators under GST and face distinct compliance obligations regardless of whether they are themselves making supplies in India.
Tax Collection at Source — TCS
E-commerce operators are required to collect Tax at Source at 1% of the net value of taxable supplies made through their platform by suppliers registered under GST. The TCS collected must be remitted to the government by the 10th of the month following the month of collection and reported in a separate TCS return — GSTR-8 — filed monthly. The TCS collected is reflected in the supplier's GSTR-2B and can be claimed as a credit against their GST liability.
Foreign Marketplace Operators and Indian TCS Obligations
Foreign marketplace operators facilitating supplies by Indian sellers face a particular compliance question — whether their obligation to collect TCS applies even where they are not incorporated in India. The GST law does not provide an explicit exemption for foreign marketplace operators and the practical position increasingly requires foreign platforms with significant Indian seller bases to register for GST in India and comply with TCS obligations.
We advise foreign marketplace operators on their TCS registration requirements, platform-level compliance architecture, seller GSTIN validation processes, and monthly GSTR-8 filing obligations.
Online Gaming — GST at 28 Percent
Following the Finance Act 2023 amendments, online gaming — including fantasy sports, online card games, and real money gaming platforms — is subject to GST at 28% on the full face value of bets or entry fees, not on the platform fee or gross gaming revenue. This amendment fundamentally changed the economics of online gaming in India and created significant retrospective liability for platforms that had been paying GST on platform fees at 18%.
Foreign online gaming companies providing services to Indian users — whether through OIDAR registration or through an Indian subsidiary — face the 28% GST rate on the full contest entry fee or bet amount. We advise on the GST structuring of online gaming platforms, the distinction between games of skill and games of chance for GST purposes, and compliance with the 28% rate including retrospective period management.
Digital Advertising Services — GST on Foreign Ad Platforms
Foreign digital advertising platforms — search engines, social media platforms, programmatic advertising networks — that provide advertising services to Indian businesses are providing OIDAR services. Indian businesses purchasing advertising on foreign digital platforms are subject to reverse charge GST on the advertising spend — with the Indian advertiser paying 18% IGST under reverse charge and claiming it as ITC.
We advise Indian businesses on their reverse charge obligations on foreign digital advertising spend and assist foreign advertising platforms on their OIDAR registration requirements where their Indian customer base includes significant B2C or small business volumes below the GST threshold.
