New Delhi: The Income Tax Act, 2025 officially replaced the six-decade-old Income Tax Act, 1961 starting April 1, 2026, ushering in one of the most significant overhauls in India’s direct tax system. Aimed at boosting predictability, transparency, and ease of compliance, the new law condenses the entire framework while keeping core tax policies untouched. From a unified “Tax Year” to merged declaration forms, expanded search powers over virtual assets, and fresh exemptions on salary perks, every aspect has been re-engineered for today’s digital economy. This comprehensive guide covers every provision, notification, and practical impact announced so far.
Structural Overhaul: Leaner Law, Same Policy
The new Act slashes the number of sections from 819 to 536 and schedules from 14 to 16. Forms have been dramatically reduced from 390 to 190, while rules drop from 511 to 333. The government has used simpler language, integrated provisos into main text, replaced lengthy narratives with tables and formulas, and eliminated excessive cross-referencing. Most definitions remain unchanged, and there are zero alterations to tax rates, regimes for individuals or corporations, offences, or penalties.
A standout feature is the separation of Minimum Alternate Tax (MAT) and Alternate Minimum Tax (AMT) into distinct sub-sections. MAT continues to target “zero tax companies” that report substantial book profits and pay dividends yet pay little or no tax because of incentives. AMT applies similar rules to non-corporate taxpayers, but MAT itself is restricted to corporate taxpayers only.
The traditional distinction between Financial Year (FY) and Assessment Year (AY) has been merged into a single “Tax Year.” Importantly, this alignment with the existing financial year means businesses and individuals do not need to change their accounting periods or financial statements.
Search and Seizure Powers Modernised for Digital Age
The definition of undisclosed income in search cases now explicitly includes virtual digital assets, expanding beyond the earlier list of money, bullion, jewellery, and valuable articles. Income-tax authorities can now access “virtual digital space” during raids. This term covers email servers, social media accounts, online investment and trading platforms, and any websites storing asset ownership details. These updates reflect the growing role of digital assets in the economy.
Official Rollout Timeline and Notifications
The Bill was passed by Parliament on 12 August 2025 and received Presidential assent on 21 August 2025, becoming the Income-tax Act, 2025 via Gazette Notification. The Central Board of Direct Taxes notified the Income-tax Rules, 2026 on 20 March 2026 to operationalise the new provisions. All corresponding new forms have also been notified—simplified, standardised, and re-engineered for easier compliance. The PIB release on 1 April 2026 at 8:37 PM (Release ID: 2248005) described the reform as a landmark step toward Viksit Bharat, marking a shift to greater clarity without changing underlying tax policy.
Key Form Changes That Directly Affect Individuals
Taxpayers no longer need to choose between Form 15G and Form 15H for preventing excess TDS. Both declarations have been merged into a single unified Form 121 under Section 393(6), applicable to all declarants irrespective of age. Form 26AS has been renamed Form 168. Tax audit reports previously filed as Forms 3CA, 3CB, and 3CD are now consolidated into one smart Form 26. PAN and TAN applications have been split into category-specific forms (individuals versus companies) so only relevant fields appear, reducing errors and time.
Salary and Perquisite Changes Under the Old Tax Regime
While income-tax slabs remain identical to those announced in Budget 2026, several exemptions and perquisite valuations have been updated from 1 April 2026, primarily benefiting salaried employees under the old regime:
- Children’s education allowance rises from ₹100 per month to ₹3,000 per month per child.
- Hostel expenditure allowance jumps from ₹300 per month to ₹9,000 per month per child.
- House Rent Allowance (HRA) exemption now covers four additional cities—Ahemdabad, Bengaluru, Hyderabad, and Pune—at 50 per cent of salary (previously limited to Chennai, Delhi, Kolkata, and Mumbai at 40 per cent in those metros).
- Corporate meal cards (free food and non-alcoholic beverages) are now tax-free up to ₹200 per meal, up from ₹50.
- Corporate gift cards, gift certificates, or coupons enjoy an annual exemption limit of ₹15,000.
- Allowance for employees in any transport system increases from ₹10,000 per month or 70 per cent (whichever lower) to ₹25,000 per month or 70 per cent (whichever lower).
Corporate loans at zero or below-market interest rates will now attract tax on the difference between the State Bank of India’s lending rate and the actual rate charged, except for loans below ₹2 lakh (previously ₹20,000) and those for medical emergencies, which remain fully tax-free.
On the cost side, perquisite valuation for employer-provided vehicles used for both official and personal purposes has risen. Cars with engines up to 1.6 litre attract ₹8,000 per month tax; larger vehicles attract ₹10,000 per month. This applies under both old and new regimes. Chartered Accountant Nitin Kaushik noted that an executive using a 1.8-litre SUV could see the taxable perquisite jump from roughly ₹2,400 to ₹7,000 monthly, plus an extra ₹3,000 if a chauffeur is provided—potentially adding over ₹1.2 lakh to annual taxable income.
Securities Transaction Tax (STT), Buyback, and TCS Rationalisation
The government has also adjusted transaction-level taxes effective 1 April 2026:
- STT on equity futures rises from 0.02 per cent to 0.05 per cent.
- STT on options increases from 0.1 per cent to 0.15 per cent.
- Proceeds from share buybacks are now taxed as capital gains. Promoter shareholders face a differential buyback tax—22 per cent for corporate promoters and 30 per cent for non-corporate promoters.
TCS rates have been rationalised to reduce refund delays and confusion:
- TCS on alcoholic drinks goes up from 1 per cent to 2 per cent.
- TCS on overseas tour packages is reduced from the earlier 5 per cent and 20 per cent slabs to a flat 2 per cent.
- TCS on Liberalised Remittance Scheme (LRS) remittances for overseas tour packages becomes a single flat 2 per cent with no threshold (earlier dual rates of 5 per cent and 20 per cent).
- TCS on LRS remittances for education and medical treatment drops from 5 per cent to 2 per cent.
Labour Codes Add Another Layer to Take-Home Pay
Simultaneous implementation of the new labour codes requires companies to treat at least 50 per cent of salary as basic wage. For employees earning ₹15,000 or more, the minimum monthly PF contribution is fixed at ₹1,800, with any higher contribution remaining discretionary. Since many firms contribute 12 per cent of basic pay to PF, increasing the basic component to meet the 50 per cent rule may reduce the “special allowance” or flexi-benefit portion, thereby lowering net in-hand salary.
Additional Compliance and Digital Reforms on 1 April 2026
All digital payment transactions must now follow two-factor authentication norms mandated by the Reserve Bank of India. Revised rules for applying for or updating a PAN card also took effect, alongside the updated FASTag annual pass fee for financial year 2026-27.
Presumptive Taxation, TDS/TCS, and Transition Provisions Simplified
Section 263 now consolidates rules for original, belated, revised, and updated returns into one section. All presumptive taxation schemes (earlier spread across Sections 44AD, 44ADA, and 44AE) are unified under Section 58. TDS provisions for non-salary payments, previously scattered across Sections 192 to 194T, are now presented in a single tabular format under Section 393, clearly listing nature of income, thresholds, and rates.
The government has assured taxpayers that the tax burden remains unchanged. Existing PAN and TAN numbers stay valid. Proceedings related to tax years before 1 April 2026 continue under the 1961 Act. Returns for income earned in FY 2025-26 will still use old ITR forms and be governed by the previous law, even if filed after the new Act’s commencement. Faceless collection of information and assessment processes remain operational.
Why the Government Undertook This Reform
Over six decades, the 1961 Act had accumulated numerous amendments, provisos, and explanations that made it difficult to navigate. The 2025 Act presents the identical tax policy in a more logical, reader-friendly format using modern legislative drafting standards. It promotes voluntary compliance, eases doing business, and aligns India’s system with global best practices. For small taxpayers, the shift means less reliance on expert interpretation and easier digital integration.
What Taxpayers Should Do Now
The transition is designed to be smooth, but salaried individuals, F&O traders, frequent overseas remitters, and companies providing perks should review their salary structures and compliance calendars immediately. The new exemptions on education, hostel, meals, gifts, and HRA can reduce taxable income under the old regime, while higher vehicle perquisites and STT may increase costs elsewhere.

The Income-tax Act, 2025 marks a new chapter in India’s tax administration—leaner, digital-ready, and focused on ease of compliance—without altering the fundamental tax liability for any citizen or business. As the first Tax Year under the new law begins, millions of taxpayers will experience a noticeably simpler filing journey while the government continues its journey toward a fully modernised, transparent, and taxpayer-centric system.
FAQs
1. When did the new Income Tax Act 2025 come into effect and what does it replace?
The new Income Tax Act, 2025 officially came into force on April 1, 2026, replacing the six-decades-old Income Tax Act, 1961. The objective of this landmark reform is to enhance predictability, transparency, and reduce compliance burden through simpler language, streamlined structure, and fewer forms. The Act has been condensed from 819 sections to 536 sections and forms reduced from 390 to 190, while keeping core tax rates, regimes, offences, and penalties completely unchanged.
2. What are the major changes in forms under the new Income Tax Act 2025?
Several important forms have been simplified and merged under the Income Tax Act, 2025:
• Form 15G and Form 15H have been merged into a single unified Form 121 applicable to all declarants regardless of age for preventing excess TDS.
• Form 26AS has been renamed as Form 168.
• Tax audit reports (Forms 3CA, 3CB, and 3CD) are now consolidated into one smart Form 26.
• PAN and TAN applications have been split into category-specific forms to show only relevant fields. These changes aim to make compliance easier and reduce confusion for individual taxpayers.
3. How does the new Income Tax Act 2025 affect salaried employees’ take-home salary and exemptions?
While income tax slabs remain unchanged, several exemptions under the old tax regime have been revised from April 1, 2026:
• Children’s education allowance increased to ₹3,000 per month per child (from ₹100).
• Hostel expenditure allowance raised to ₹9,000 per month per child (from ₹300).
• HRA exemption now includes four new cities — Ahmedabad, Bengaluru, Hyderabad, and Pune at 50%.
• Meal card exemption increased to ₹200 per meal (from ₹50).
• Corporate gift coupons exemption raised to ₹15,000 per year.
• Perquisite tax on employer-provided cars has increased (₹8,000/month for cars up to 1.6L engine and ₹10,000/month for larger vehicles). Additionally, low-interest corporate loans above ₹2 lakh will now be partially taxable. These changes can positively or negatively impact in-hand salary depending on the salary structure.
4. Does the new Income Tax Act 2025 change tax rates or introduce new taxes?
No. The Income Tax Act, 2025 does not change tax rates, tax regimes for individuals or corporations, or introduce any new taxes. The reform focuses purely on simplification — merging concepts like Financial Year and Assessment Year into a single “Tax Year”, using clearer language, and reducing the overall size of the law. However, certain transaction taxes like Securities Transaction Tax (STT) on futures and options, and TCS rates on overseas remittances and alcoholic drinks have been adjusted.
5. Will I need to change my accounting year or file returns differently under the new ‘Tax Year’ concept?
No change is required in your accounting period. The new “Tax Year” concept simply merges the old Financial Year (FY) and Assessment Year (AY) into one unified term, but it remains aligned with the existing financial year (April–March). Proceedings related to tax years before April 1, 2026 will continue under the old 1961 Act. Returns for income earned in FY 2025-26 will still use the old ITR forms even if filed after April 1, 2026. Existing PAN and TAN numbers remain valid.
