menu_book 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.

Important: Verify with Official Sources

This tool is prepared based on the Income Tax Act, 2025 as enacted by Parliament. However, the CBDT is still issuing final rules and notified forms through the Draft Income Tax Rules, 2026. Section mappings, form numbers, and filing procedures are subject to change. Always verify the latest provisions with official sources including the Income Tax portal (incometax.gov.in), CBDT notifications, and consult a qualified Chartered Accountant for specific tax planning advice. For estimating your total tax including surcharge and cess, use our Surcharge & Cess Calculator.

help_outline Frequently Asked Questions (People Also Ask)

Is Form 16 still valid for Tax Year 2026-27? expand_more
Yes, but it has been renumbered. Under the Draft Income Tax Rules, 2026, Form 16 is now called Form 111. It continues to serve as the salary TDS certificate, but with updated section references. The standard deduction is now ₹75,000 (under Section 19), and the new regime is the default. Employers will issue Form 111 instead of Form 16 starting from Tax Year 2026-27 (effective April 1, 2026). NOTE: Form 111 is from Draft Rules and may change before final notification.
What happened to Section 80C in the new Income Tax Act, 2025? expand_more
Section 80C has been renumbered to Section 123 under the Income Tax Act, 2025. The deduction limit of ₹1.5 Lakh remains the same, and eligible investments (PPF, ELSS, NSC, LIC, etc.) continue to qualify. However, this deduction is only available under the old tax regime. To claim Section 123 deductions, you must file the designated declaration form (form number awaiting CBDT notification) to opt out of the default new tax regime. The new regime does not offer Section 123/80C benefits.
What is the new Section 194T for partner TDS? expand_more
Section 194T is a brand-new provision under the Income Tax Act, 2025 that introduces 10% TDS on payments to partners by a firm. This includes salary, bonus, commission, or remuneration paid to partners exceeding ₹20,000. This provision never existed in the 1961 Act and is part of the unified Section 393. It applies from Tax Year 2026-27 and is a major compliance change for partnership firms.
What is the tax rebate under Section 156? expand_more
Section 156 (formerly Section 87A) provides an enhanced rebate of ₹60,000 under the new tax regime for Tax Year 2026-27. This means individuals with taxable income up to ₹12 Lakh effectively pay zero tax. Combined with the ₹75,000 standard deduction (Section 19), salary income up to approximately ₹12.75 Lakh is tax-free under the new regime. This rebate is auto-applied when filing ITR under the default new regime.
Do I need to file a form to opt for the old regime? expand_more
Yes, if you want to claim old regime deductions. Under the Income Tax Act, 2025, the new tax regime (Section 202) is the DEFAULT. If you want to claim deductions like Section 123 (80C), Section 126 (80D), HRA exemption, or home loan interest (Section 22), you must file the designated opt-out declaration form (form number to be notified by CBDT) before the return due date. This is the reverse of the old system where Form 10-IE/10-IEA was used to opt FOR the new regime. The specific form number for opting OUT under the 2025 Act is awaited from CBDT.
What happened to Form 15G and 15H? expand_more
Form 15G and Form 15H have been merged into a single unified Form 121 under the Income Tax Act, 2025. There is no longer a separate form based on age. Form 121 is used to declare that your income is below the taxable limit so that no TDS is deducted on interest income. The income threshold now considers the enhanced rebate of ₹60,000 (taxable income up to ₹12 Lakh) under the new regime.
Is ITR-4 (Sugam) still available under IT Act 2025? expand_more
Yes, ITR-4 (Sugam) continues for Tax Year 2026-27 under the Income Tax Act, 2025. It is used for presumptive taxation under Section 58 (which consolidates old Sections 44AD, 44ADA, and 44AE). Business income can be declared at 8% of turnover (6% for digital), and professional income at 50% of gross receipts. The new regime is default for presumptive taxpayers as well.
