1. Introduction of the Income Tax Act, 2025

One of the biggest reforms is the introduction of the Income Tax Act, 2025, which will completely replace the Income Tax Act, 1961.

Why a New Tax Act?

The previous law had become complex over time due to:

• Multiple amendments
• Legal interpretations
• Outdated provisions

Objectives of the New Act

The new law aims to:

• Simplify tax language for better understanding
• Remove redundant and outdated provisions
• Reduce litigation and disputes
• Make compliance easier for taxpayers
• Improve transparency in tax administration

Overall, this reform is designed to make the Indian tax system more modern, efficient, and taxpayer-friendly.

2. Income Tax Rules, 2026

Along with the new Act, Income Tax Rules, 2026 will also come into force. These rules redefine how deductions, allowances, and reporting requirements are handled.

Major Improvements

• Updated deduction limits to reflect current economic conditions
• Simplified documentation requirements
• Revised PAN-related compliance
• Introduction of new reporting formats

Updated Allowances and Benefits

The government has significantly increased limits on several employee benefits:

• Free Meal Limit increased from ₹50 to ₹200 per meal

For company-provided vehicles:

• Higher perquisite valuation limits depending on engine size

For medical treatment abroad:

Impact

These changes are particularly beneficial for salaried individuals, as they increase tax-free components of salary and improve overall tax efficiency.

3. Income Tax Slabs for FY 2026–27

Despite major structural changes, income tax slabs remain unchanged under the new tax regime.

Current Tax Rates

• Up to ₹4 lakh – No tax
• ₹4–8 lakh – 5%
• ₹8–12 lakh – 10%
• ₹12–16 lakh – 15%
• ₹16–20 lakh – 20%
• ₹20–24 lakh – 25%
• Above ₹24 lakh – 30%

Rebate Benefit

Taxpayers opting for the new regime can claim a rebate of up to ₹60,000 under Section 87A. This effectively makes income up to ₹12 lakh tax-free.

What This Means

Although tax rates remain the same, increased deductions and simplified rules improve overall tax savings.

4. Introduction of the “Tax Year” Concept

A major conceptual change is the replacement of:

• Financial Year (FY)
• Assessment Year (AY)

with a single term: Tax Year

Why This Change Matters

Previously, many taxpayers found it confusing to differentiate between FY and AY. The introduction of the Tax Year simplifies:

• Filing process
• Tax calculations

This is a major step toward making taxation more user-friendly.
