Complete Guide: Old IT Act 1961 vs New Income Tax Act, 2025
The Income Tax Act, 2025 has brought the most comprehensive overhaul of India's tax system in over six decades. This tool provides a detailed side-by-side comparison of every major form, section, and compliance requirement under the old IT Act 1961 and the new IT Act 2025. Whether you are a salaried individual, business owner, tax professional, or chartered accountant, this tool helps you quickly find how your familiar forms and sections have changed, been renumbered, or replaced under the new law. Key Conceptual Change: The new Act introduces the unified concept of "Financial Year" which replaces the old dual system of "Financial Year (FY)" and "Assessment Year (AY)". The concept of "Assessment Year" has been entirely abolished. For example: Instead of FY 2025-26 and AY 2026-27, all income earned and assessed will simply fall under Financial Year 2026-27 (also referred to as "Tax Year" in some contexts). This eliminates the perennial confusion between FY and AY. To understand how this affects your tax liability, use our Old vs New Tax Regime Calculator.
What Has Changed Under Income Tax Act, 2025?
The new Income Tax Act consolidates and renumbers hundreds of sections from the original 1961 legislation. While many core concepts remain the same, the section numbers, forms, filing processes, and compliance requirements have been significantly updated. The most notable changes include the new default tax regime with revised slabs and enhanced standard deduction of ₹75,000, renumbered TDS/TCS sections for better organization, digital-first compliance through the redesigned Income Tax portal, and the introduction of the Annual Information Statement (AIS) alongside Form 114 (formerly Form 26AS). Calculate your exact tax liability with our Income Tax Calculator 2026.
Section 393 — Unified TDS Section (Formerly 194A-194T)
Under the new Income Tax Act, 2025, over 30 non-salary TDS sections (194A through 194T) have been consolidated into a single Section 393. This is a major simplification for tax professionals. Important Note on Threshold Limits: The individual threshold limits for each payment type remain separate and are NOT pooled. For example, TDS on bank interest still has a ₹40,000 threshold, contractor payments have a ₹30,000 threshold (₹1 Lakh aggregate), and professional fees have a ₹30,000 threshold. These sub-limits continue to apply independently under the unified Section 393 framework. The consolidation simply means one section number for reference, but the underlying rate structure and thresholds remain distinct for each payment category. Use our TDS Calculator to compute TDS on various payments.
