Tax Avoidance, Evasion and GAAR: McDowell to Tiger Global

Every taxpayer may arrange his affairs to pay less tax, but the law draws a line. Tax planning within the law's intent is legitimate; evasion through concealment or fraud is a crime; avoidance sits in between, lawful in form but contrary to the purpose of the law. Indian courts have moved between these positions for decades, and Parliament added a General Anti-Avoidance Rule from 2017. This note traces the cases and explains GAAR.

1. Planning, Avoidance and Evasion

Figure 1: Three concepts

• Tax planning. Choosing among options the law offers, such as investing for a deduction, in line with the policy behind the relief.
• Tax avoidance. Arrangements that comply with the letter of the law but defeat its purpose, often through steps with no commercial reason.
• Tax evasion. Reducing tax by illegal means such as concealing income, inflating expenses or falsifying records; it attracts penalty and prosecution.

2. How the Cases Developed

Figure 2: From Westminster to Tiger Global

• Duke of Westminster (1936). The House of Lords held that every man is entitled to order his affairs so that the tax is less than it would otherwise be.
• McDowell and Co. v CTO (1985). A Constitution Bench held that tax planning may be legitimate within the framework of law, but colourable devices cannot be part of it, and it is wrong to encourage the belief that it is honourable to avoid tax by dubious methods.
• Azadi Bachao Andolan (2003). The Court upheld the CBDT circular accepting Mauritian residence certificates as sufficient for treaty benefits, held that treaty shopping is not illegal in itself, and read McDowell as not overruling Westminster.
• Vodafone (2012). A three judge bench held that the transfer of shares of an offshore company, which indirectly held Indian assets, was not taxable in India. The Revenue may look at a transaction as a whole, but cannot treat a genuine structure as a sham.

3. Retrospective Amendment and Its Withdrawal

Parliament responded to Vodafone through the Finance Act, 2012, which clarified retrospectively that a share in a foreign company deriving substantial value from Indian assets is situated in India. The amendment drew international arbitration. The Taxation Laws (Amendment) Act, 2021 provided that no demand would be raised under it for transfers before 28 May 2012, and that demands already raised would be withdrawn on conditions, including withdrawal of pending litigation.

4. The General Anti-Avoidance Rule

Figure 3: Impermissible avoidance arrangement

• Origin. Introduced as Chapter X-A (ss.95 to 102) of the 1961 Act and effective from 1 April 2017; carried forward into the Income-tax Act, 2025.
• Test. An arrangement whose main purpose is a tax benefit, and which has at least one tainted element: rights or obligations not at arm's length, misuse or abuse of the Act, lack of commercial substance, or means or manner not normally employed for bona fide purposes.
• Consequence. The tax benefit is denied, and the arrangement may be disregarded, combined or recharacterised; treaty benefits may also be denied.
• Safeguards. Reference to an Approving Panel; under Rule 10U of the 1961 Rules, GAAR did not apply where the tax benefit was up to Rs 3 crore, and income from investments made before 1 April 2017 was protected.

5. Tiger Global (2026)

Tiger Global's Mauritius entities sold shares of Flipkart's Singapore holding company during Walmart's acquisition and claimed exemption under the India-Mauritius treaty. The Authority for Advance Rulings found the arrangement prima facie for tax avoidance; the Delhi High Court reversed it. In January 2026, the Supreme Court restored the AAR's ruling. It held that a tax residence certificate is not conclusive, that the grandfathering of pre-2017 investments does not protect an arrangement yielding a tax benefit after that date, and that treaty benefits may be denied on a substance over form analysis.

6. Frequently Asked Questions

What is the difference between tax avoidance and tax evasion?

Avoidance uses lawful means to reduce tax, often against the purpose of the law, and is countered by anti-avoidance rules. Evasion uses illegal means such as concealment or falsification, and attracts penalty and prosecution.

Did McDowell overrule the Westminster principle?

No. In Azadi Bachao Andolan (2003), the Supreme Court read McDowell as condemning colourable devices, not as overruling the right to plan one's affairs within the law; Vodafone (2012) took the same view.
