The Income Tax Act 2025 is set to come into force from April 1, marking a significant reform in India’s direct tax framework. The new legislation replaces the six-decade-old Income Tax Act 1961, which has undergone numerous amendments over the years and has become lengthy and complex.
However, despite the introduction of the Income Tax Act 2025, taxpayers should note that tax slabs and tax rates are not expected to change immediately. Government officials have clarified that the primary objective of the new law is to simplify and modernise India’s tax structure, rather than introduce new tax rates.
The Income Tax Act 2025 implementation date aligns with the start of the new financial year, ensuring a smooth transition from the older legislation to the new simplified framework.
No Change in Tax Slabs or Rates Under Income Tax Act 2025
One of the most important clarifications regarding the Income Tax Act 2025 is that existing tax slabs and tax rates will remain unchanged. Both the old tax regime and the new tax regime will continue to apply as they currently exist.
Tax experts have confirmed that the purpose of introducing the Income Tax Act 2025 is primarily to remove outdated provisions, reorganise sections, and simplify legal language. Any revisions to tax rates or slabs will continue to be announced through the Union Budget, just as under the existing system.
This means that taxpayers will not see immediate changes in their tax liability for FY 2025-26 or FY 2026-27 simply because the new law has been introduced.
New Tax Regime: Default System for FY 2026-27
The new tax regime will remain the default option under the Income Tax Act 2025, continuing the policy introduced in previous years.
Under this regime, individuals earning up to ₹12 lakh annually may effectively have zero tax liability after applying the Section 87A rebate, provided the income is considered normal taxable income. Special-rate incomes such as capital gains are excluded from this calculation.
New Tax Regime Slabs
-
₹0 – ₹4,00,000: Nil
-
₹4,00,001 – ₹8,00,000: 5%
-
₹8,00,001 – ₹12,00,000: 10%
-
₹12,00,001 – ₹16,00,000: 15%
-
₹16,00,001 – ₹20,00,000: 20%
-
₹20,00,001 – ₹24,00,000: 25%
-

Salaried individuals will still have the option to switch to the old tax regime while filing their income tax return. However, if a taxpayer files a belated ITR, they will only be allowed to file under the new tax regime.
Key Benefits Under the New Tax Regime
The Income Tax Act 2025 retains several important benefits under the new tax regime, which aim to make the system simpler and more taxpayer-friendly.
The standard deduction for salaried employees and pensioners is ₹75,000, which reduces taxable income directly. Additionally, the Section 87A rebate allows resident taxpayers with taxable income up to ₹12 lakh to eliminate their tax liability.
Another important benefit is the NPS contribution deduction under Section 80CCD(2). Salaried employees can claim a deduction of up to 14% of basic salary for employer contributions to the National Pension System.
Old Tax Regime: Suitable for Deduction-Focused Taxpayers
Although the new tax regime remains the default, many taxpayers still prefer the old tax regime due to the wide range of deductions and exemptions available.
The old regime allows taxpayers to claim deductions under Section 80C, including investments in PPF, ELSS, and LIC, up to ₹1.5 lakh. Additional deductions are available for health insurance premiums under Section 80D, education loan interest under Section 80E, and home loan interest under Section 24.
Salaried taxpayers can also claim House Rent Allowance (HRA), Leave Travel Allowance (LTA), and a standard deduction of ₹50,000.
Old Tax Regime Slabs for Individuals Below 60
-
₹0 – ₹2,50,000: Nil
-
₹2,50,001 – ₹5,00,000: 5%
-
₹5,00,001 – ₹10,00,000: 20%
-
Above ₹10,00,000: 30%
Different slabs continue to apply for senior citizens and super senior citizens.
Objective of the Income Tax Act 2025
The Income Tax Act 2025 aims to simplify India’s tax legislation, which has grown complex after decades of amendments to the Income Tax Act 1961.
The new law focuses on reorganising provisions, simplifying legal language, and improving clarity in definitions. This restructuring is expected to make tax compliance easier for both taxpayers and administrators while reducing interpretation disputes.
Experts believe that although taxpayers may not see immediate financial changes, the simplified framework under the Income Tax Act 2025 will significantly improve transparency and ease of compliance.
The Income Tax Act 2025, effective from April 1, represents an important reform in India’s tax system. However, taxpayers should understand that tax slabs and rates will remain unchanged for now.
Instead, the focus of the Income Tax Act 2025 is on simplifying the tax law, removing outdated provisions, and improving clarity. Any changes to tax rates will continue to be introduced through the annual Union Budget, ensuring continuity in India’s tax policy.
