Taxation Basics for Foreign Investors in India: A Short Legal Guide

Foreign investors and researchers examining India’s tax law as part of a broader legal or business study usually need a short map of the system before anything else makes sense, since Indian tax law runs on more statutes than most single-jurisdiction comparisons expect.

Direct tax: a code mid-overhaul

Income tax in India was governed by the Income-tax Act, 1961 for over six decades; a new Income-tax Act, 2025 has now been enacted to replace it with simplified language and structure, effective from April 2026, though its substantive rules largely carry forward the 1961 Act’s framework (residency tests, heads of income, deductions) rather than reinventing them. Foreign investors should note the three residential-status categories (resident, resident but not ordinarily resident, and non-resident) that determine how much of a person’s or entity’s global income India can tax.

Indirect tax: GST’s single-tax reform

The Goods and Services Tax (GST), introduced in 2017 under the 101st Constitutional Amendment, replaced a patchwork of central excise duty, state VAT, service tax, and other indirect levies with a single, though still multi-rate, tax administered jointly by the centre and states through the GST Council, a cooperative-federalism body often cited in its own right as a model of centre-state fiscal coordination.

Double taxation and transfer pricing

India has Double Taxation Avoidance Agreements (DTAAs) with over 90 countries, and foreign investors structuring an India entry typically need to assess both the DTAA with their home jurisdiction and India’s transfer pricing rules (Sections 92 to 92F of the Income-tax Act), which require related-party transactions to be priced at arm’s length and are enforced through a dedicated Transfer Pricing Officer mechanism, an area generating a substantial share of India’s tax litigation.

Where professional advice is still essential

This guide is educational, not tax advice; foreign investors should engage a qualified chartered accountant or tax counsel for entity structuring, withholding tax computation, and DTAA treaty-benefit claims specific to their home jurisdiction.

Lexfolio’s Income-tax Act 2025 and GST course covers the compliance mechanics of both regimes for readers who want the applied version.
