Income Tax Act 2025 — Key Changes Every Taxpayer Must Know
The Income Tax Act 2025 replaces the Income Tax Act 1961 — India's most significant tax law reform in six decades. This guide decodes the key changes in slab rates, zero-tax threshold, capital gains, TDS rationalisation, presumptive taxation, and compliance simplification that affect every Indian taxpayer from AY 2026-27.

The Income Tax Act 2025 — passed by Parliament in February 2025 and effective from 1 April 2026 (AY 2026-27) — is India's most comprehensive tax law overhaul since 1961. While retaining the structural framework, it simplifies language, consolidates provisions, rationalises tax rates, and overhauls TDS compliance. Here is what every taxpayer, business, and NRI needs to know.
The Income Tax Act 2025 is largely a consolidation and simplification exercise — it rewrites the 1961 Act in plain language, removes redundant provisions, and modernises the structure. Key changes include:

Old Act (1961)
New Act (2025)

₹12 lakh (enhanced 87A rebate)

Important Note
The Income Tax Act 2025 renumbers many sections. The substance of provisions largely remains the same, but section references in old contracts, court orders, and tax notices will need to be mapped to new section numbers. Our CA team has the complete mapping table.
New Income Tax Slabs — Zero Tax up to ₹12 Lakh
The most significant taxpayer-friendly change: individuals with income up to ₹12 lakh effectively pay zero income tax under the new regime, thanks to the enhanced Section 87A rebate of ₹25,000 (up from ₹12,500).

Tax at ₹12 lakh income: ₹0 + ₹20,000 + ₹30,000 + ₹30,000 = ₹80,000 — fully offset by Section 87A rebate of ₹25,000 and the marginal relief provision. Net tax = ₹0.
For salaried employees: After standard deduction of ₹75,000, income up to ₹12.75 lakh results in zero tax liability.
87A Rebate on Special Rate Income
The enhanced 87A rebate of ₹25,000 does not apply to special rate incomes like STCG on equity (20%), LTCG on equity (12.5%), and lottery winnings. Even if total income is below ₹12 lakh, special rate income tax must be paid separately without 87A offset. This is a crucial planning point for investors.
Impact on Salaried Employees — What Changed
Standard deduction increased: ₹75,000 (new regime) vs ₹50,000 (old regime). New regime is now default.
Zero tax effectively up to ₹12.75 lakh for salaried — making the new regime highly attractive for most employees
Section 80C deductions: Still NOT available under new regime. If 80C investments + HRA + home loan interest exceed ₹3 lakh, old regime may still be beneficial.
Leave encashment exemption: Limit enhanced to ₹25 lakh (from ₹3 lakh). Applicable to non-government employees at retirement.
NPS employer contribution: Deduction under new section (erstwhile 80CCD(2)) increased to 14% of salary (from 10%) for both private and government employees.
Perquisites: Tax treatment of perquisites rationalised. Employer-provided accommodation and car perquisites have revised valuation rules.
Capital Gains Tax — Major Restructuring
Capital gains taxation has been significantly restructured — effective from 23 July 2024 (Budget 2024) and codified in the Income Tax Act 2025:
Equity and Equity Mutual Funds
LTCG rate: Raised from 10% to 12.5%. Holding period: >12 months. Exemption limit raised to ₹1.25 lakh per year (from ₹1 lakh).
STCG rate: Raised from 15% to 20%. Holding period: ≤12 months.
Indexation on equity: Never applied — no change here.
Immovable Property (Land & Buildings)
LTCG rate:12.5% without indexation (previously 20% with indexation). Holding period: >24 months.
Indexation removed: The Cost Inflation Index (CII) benefit is no longer available on property sold after 23 July 2024. For property purchased before 2001, fair market value as of 1 April 2001 is allowed as cost.
Option for pre-July 2024 property: For property acquired before 23 July 2024, taxpayers can choose between: (a) 12.5% without indexation OR (b) 20% with indexation — whichever gives a lower tax liability.
Exemptions retained: Section 54 (reinvest in residential property), Section 54EC (NHAI/REC bonds up to ₹50 lakh), Section 54F (invest net consideration in residential property)
Debt Mutual Funds and Bonds
Debt MF (purchased after 1 April 2023): Taxed at slab rate — no LTCG/STCG distinction. This was introduced in March 2023 and continues under the new Act.
Listed bonds: LTCG at 12.5% (holding >12 months); STCG at slab rate.
Unlisted bonds/debentures: LTCG at 12.5% without indexation (holding >24 months).
Capital Gains Planning — Act Now
The removal of indexation on property LTCG significantly increases tax liability for long-held properties. If you are planning to sell property, calculate both options (12.5% vs 20% with indexation for pre-July 2024 property) with our CA team to choose the optimal tax treatment.

Significant Relief
The increase in rent TDS threshold from ₹2.4 lakh to ₹6 lakh per year (i.e., ₹50,000/month) is a major relief for landlords and tenants. Many residential rental arrangements under ₹50,000/month are now free from TDS obligation under Section 194-I.
Changes for Businesses and Self-Employed
Presumptive tax for businesses (erstwhile 44AD): Limit retained at ₹3 crore (10 crore for digital transactions). Rate 8% of gross turnover (6% for digital receipts).
Presumptive for professionals (erstwhile 44ADA): Limit retained at ₹75 lakh. Rate: 50% of gross receipts deemed as profit.
Business loss carryforward: Losses can now be carried forward for 10 years (previously 8 years).
Updated return (erstwhile 139(8A)): Facility to file updated return extended to 4 years from the end of AY (previously 2 years). Additional tax of 60% applies for 3rd and 4th year.
Angel Tax abolished: Section 56(2)(viib) (Angel Tax) has been removed for all investors — a relief for startups. Investments by foreign and domestic investors are no longer taxable under this provision.
Startup deductions (erstwhile 80-IAC): Tax holiday for eligible startups continued — 100% deduction for 3 out of 10 years.
High Networth Individuals — Surcharge & Special Rates
Surcharge on income >₹50 lakh: 10% surcharge (new regime). 15% for income >₹1 crore. 25% for >₹2 crore.
Surcharge cap on LTCG/STCG: Maximum surcharge on LTCG (equity) capped at 15% — unchanged.
STCG at 20% + 15% surcharge + 4% cess: Effective STCG rate for HNIs with income >₹5 crore = 20% × 1.37 = 27.4% approximately.
Buyback taxation: From 1 Oct 2024, buyback proceeds are taxable in the hands of shareholders as dividend income (not as capital gains). This is a significant change for listed company shareholders participating in buybacks.
Trust taxation: Revised provisions for charitable trusts — corpus donations and accumulations have revised rules. Consult our team for trust-specific impact.
NRI Taxation Changes
Deemed resident threshold: Indian citizens in zero-tax jurisdictions with India income >₹15 lakh remain deemed residents (unchanged).
NRI capital gains on property: TDS rate on NRI property sales revised — now 12.5% for LTCG transactions (revised from variable rates).
15CA / 15CB: Thresholds for Form 15CA/15CB rationalised. CA certification (15CB) required for remittances exceeding ₹5 lakh in a year — previously ₹5 lakh per transaction.
DTAA provisions: New Act clarifies DTAA override — treaty provisions continue to prevail over domestic law where beneficial (Section 90(2) equivalent retained).
Faceless assessment for NRIs: NRI assessments under the new faceless assessment system — submissions can be made online without physical presence in India.
Compliance Simplification
Annual Information Statement (AIS): Expanded AIS now captures more financial transactions. Pre-filling of ITR significantly enhanced.
Faceless assessment: Fully implemented — all scrutiny assessments conducted electronically without face-to-face interaction.
TDS credit without TDS certificate: TDS credit now based on AIS/26AS — Form 16A not mandatory if AIS reflects the credit.
Faster refunds: Target refund processing time reduced to 10 days (from current 20-30 days) with enhanced CPC processing.
Simplified ITR forms: Revised ITR forms for AY 2026-27 aligned with new Act section numbering.
Penalty rationalisation: Several redundant penalty provisions merged. Late fee under erstwhile 234F retained at ₹5,000 (₹1,000 for income ≤₹5 lakh).
FAQs — Income Tax Act 2025
Yes. Under the new regime (default), individuals with total income up to ₹12 lakh pay zero income tax due to the enhanced Section 87A rebate of ₹25,000. For salaried individuals, the standard deduction of ₹75,000 further raises the effective zero-tax limit to ₹12.75 lakh. Note: special rate income (equity STCG, lottery) is not eligible for 87A rebate.
The new regime is beneficial for most salaried individuals earning up to ₹15–20 lakh with limited deductions. The old regime remains beneficial if you have significant 80C investments (₹1.5L), home loan interest (₹2L), health insurance (80D), and HRA. Our CAs compute tax under both regimes and recommend the optimal choice. Contact us for a personalised tax computation at no cost.
From 23 July 2024 (codified in IT Act 2025): LTCG on property is 12.5% without indexation (previously 20% with CII indexation). For property acquired before 23 July 2024, you can choose between (a) 12.5% without indexation or (b) 20% with indexation — whichever gives lower tax. TDS by buyer remains 1% on purchase price above ₹50 lakh. Exemptions under Section 54, 54EC, 54F continue.
Angel Tax (Section 56(2)(viib) of the old Act) has been completely abolished in the Income Tax Act 2025. This means investments received by unlisted companies from both resident and non-resident investors are no longer taxable as income in the hands of the company, regardless of whether the share premium exceeds fair market value. This is a major relief for the startup ecosystem.
The updated return (erstwhile Section 139(8A)) allows taxpayers to voluntarily disclose additional income missed in the original return. Under the Income Tax Act 2025, the window is extended to 4 years from the end of the relevant Assessment Year (previously 2 years). Additional tax: 25% for year 1-2, 50% for year 3, and 60% for year 4 of the update. You cannot file an updated return to claim a higher refund — only to pay additional tax.
