India GST Registration for Foreign Companies: Complete 2026 Guide

Introduction

Goods and Services Tax (GST) is India's unified indirect tax that replaced a labyrinth of state and central taxes in 2017. For a foreign company setting up an Indian subsidiary, GST registration is mandatory in certain circumstances — and the threshold rules are frequently misunderstood, leading companies to either register too early and take on unnecessary compliance burden, or register too late and face retrospective liability.

This guide covers when GST registration is mandatory for a foreign-owned Indian company, the registration process, the ongoing compliance calendar, and the specific issues that foreign-owned GCCs and subsidiaries face that purely domestic companies do not.

When Is GST Registration Mandatory?

Threshold-Based Registration (Most Domestic Businesses)

For Indian companies supplying goods or services domestically, GST registration is mandatory once aggregate annual turnover exceeds INR 40 lakhs (for goods) or INR 20 lakhs (for services). Companies in certain special category states have lower thresholds of INR 20 lakhs (goods) and INR 10 lakhs (services).

Mandatory Registration Regardless of Turnover

Foreign-owned Indian subsidiaries often fall into categories where GST registration is mandatory from Day 1, regardless of whether they have crossed the threshold. These include:

Companies making inter-state supplies of goods or services

Companies making taxable supplies as an e-commerce operator

Companies required to pay GST under the reverse charge mechanism

Non-resident taxable persons conducting occasional taxable transactions in India

The GCC and Export of Services Situation

This is the most common situation for foreign-owned Indian GCCs: the Indian entity provides services exclusively to its overseas parent, billing on a cost-plus basis. These services qualify as Export of Services under GST, which means they are zero-rated — the Indian entity charges 0% GST on the invoice to the parent company.

However, zero-rated does not mean exempt from GST compliance. The Indian entity must be GST-registered, must file monthly returns, and must process refund claims for Input Tax Credit (ITC) on inputs used to provide the zero-rated service. Companies that skip GST registration under the assumption that 'we don't charge GST to our parent' face retrospective registration demands and penalties.

The GST Registration Process

Step 1 — Gather Documents

PAN of the Indian company

Proof of principal place of business: ownership documents or rent agreement

Bank account proof: cancelled cheque or bank statement with IFSC and account number

Authorised signatory details: PAN, Aadhaar, and digital signature (DSC) of the signatory

Photograph of the authorised signatory

Memorandum of Association showing nature of business

Step 2 — File GST REG-01 on the GST Portal

The application is filed on gstin.gov.in. The applicant selects the 'Normal Taxpayer' registration type for most foreign-owned subsidiaries. The application requires entering business details, place of business, nature of supply, bank account details, and uploading the documents listed above.

Step 3 — Processing and GSTIN Issuance

GST officers typically process applications within 3-7 working days. If the officer requires clarification or additional documents, they issue a notice in Form GST REG-03, to which the applicant responds in Form GST REG-04 within 7 working days. Once approved, the GSTIN (GST Identification Number) is issued — a 15-digit number beginning with your state code.

Input Tax Credit: The Refund Issue for GCCs

A GCC that exports services (charges 0% GST to its overseas parent) still pays GST on its Indian expenses — office rent, IT hardware, professional fees, and other inputs. This creates accumulated Input Tax Credit that cannot be used to offset output GST (because output GST is zero).

The mechanism to recover this is a GST refund application under Rule 89 of the CGST Rules. The refund claim covers ITC on inputs used for making zero-rated supplies. This refund process is quarterly or monthly and requires filing of RFD-01 on the GST portal, along with supporting documents.

Many GCCs leave significant refunds unclaimed simply because their accounting team is not aware of the mechanism. If your Indian GCC is paying GST on inputs but not filing refund claims, you are effectively paying a cost that you are legally entitled to recover.

Penalties for Non-Compliance

Late registration: INR 10,000 penalty for failure to register when mandatory, plus tax interest at 18% per annum on tax due from the date registration should have been obtained.

Late return filing: INR 50 per day (INR 20 for Nil returns) late fee for GSTR-1 and GSTR-3B, capped at INR 5,000 per return.

Non-filing: Suspension of GSTIN after consecutive non-filings. A suspended GSTIN means the company cannot make taxable supplies — effectively shutting down India operations.
