Madras High Court Seeks Centre Response on Retrospective Income Tax Amendments in Finance Act 2026

The Madras High Court on June 15, 2026, sought responses from the Union government and the Income Tax Department on a petition challenging retrospective amendments introduced to the Income Tax Act, 1961, through the Finance Act, 2026. A Division Bench of Chief Justice SA Dharmadhikari and Justice Arul Murugan issued notice on the plea filed by the Revenue Bar Association (RBA), which argues that the amendments retrospectively nullify High Court rulings without removing their legal basis.

The Challenged Amendments

The Revenue Bar Association challenges several amendments made with retrospective effect. These include amendments to Section 92CA of the Income Tax Act, 1961, relating to transfer pricing proceedings, which was inserted with retrospective effect from June 1, 2007. The petition also challenges retrospective changes to provisions concerning the Dispute Resolution Panel procedure, assessment timelines, reassessment, and validation of tax proceedings. The RBA argues that these amendments have the effect of validating actions that were previously held to be unlawful by High Courts, effectively overriding judicial decisions through legislative action.

Constitutional Arguments Against Retrospective Taxation

The core constitutional argument is that retrospective tax legislation, particularly when it overrides court decisions, violates Article 14 (equality before law) and Article 19(1)(g) (freedom to practise any profession, or to carry on any occupation, trade or business). The Supreme Court in Mardia Chemicals Ltd. v. Union of India (2004) held that while Parliament's power to legislate retrospectively is not in doubt, such legislation must satisfy the test of reasonableness and non-arbitrariness. The Vodafone International Holdings case (2012) also raised similar concerns about retrospective tax amendments. As covered in our analysis of new income tax rules 2026, the tax landscape continues to evolve significantly.

Implications for Taxpayers and Practitioners

If the Madras High Court rules in favour of the RBA, it could invalidate key retrospective provisions of the Finance Act 2026, providing relief to taxpayers who had won cases in High Courts that the retrospective amendments sought to nullify. The case also raises broader questions about the limits of Parliament's power to legislate retrospectively in tax matters. The matter is likely to be heard next on July 21, 2026. Tax practitioners and businesses with pending transfer pricing or reassessment proceedings should monitor this case closely.
