CBDT released comprehensive transition FAQs on 20 March 2026 to guide practitioners through the changeover from ITA 1961 to ITA 2025 on 1 April 2026. Key clarifications:
(a) Assessment jurisdiction: Income of FY 2025-26 (AY 2026-27) = governed by ITA 1961 throughout its lifecycle (return, assessment, appeal). Income from Tax Year 2026-27 onwards = governed by ITA 2025. No hybrid treatment.
(b) Pending proceedings: All assessments, reassessments, revision, and appeal proceedings initiated under ITA 1961 continue under that statute even if they conclude after 1 April 2026. The repeal does not abate proceedings.
(c) ITR-U (updated return): ITR-U for AY 2024-25, AY 2025-26, and AY 2026-27 will continue to be available under ITA 1961. Under ITA 2025, the updated return (for Tax Year 2026-27 onwards) is available for 48 months from end of Tax Year, with graduated additional tax (25% → 50% → 60% → 70% based on years elapsed).
(d) TDS returns: Q4 FY 2025-26 TDS return (January–March 2026) is filed under ITA 1961 with existing form numbers. Q1 FY 2026-27 (Tax Year 2026-27) uses new form numbers under ITA 2025 and is filed by 31 July 2026.
Practice utility: Download and circulate the CBDT FAQ document to all team members handling tax filings. Keep a printed copy as quick reference. Particularly useful for: (a) explaining transition to clients; (b) responding to client queries on whether existing assessments are affected; (c) briefing corporate accounts teams on TDS form number changes.
