The Big Question: Old or New Tax Regime? A Complete Guide for Indian Taxpayers (FY 2025-26)

Making the wrong choice could cost you a significant amount in tax.

This tax season, the single most important decision for every Indian taxpayer is choosing the right tax regime. With the new tax regime now the default, many are left wondering: should I stick with the simpler, lower-rate new regime, or is the old regime, with its valuable deductions, still the better option for me?

Making the wrong choice could cost you a significant amount in tax. This complete guide will break down both regimes, compare them side-by-side, and give you a clear framework for making the right decision for the FY 2025-26.

Understanding the Two Regimes

1. The New Tax Regime (Default)

Introduced to simplify the tax structure, the new regime operates on a “lower tax rate, no exemptions” principle. It is now the default option, which means if you don’t actively choose the old regime, your taxes will be calculated under these rules.

Key Features:

Lower Tax Rates: The new regime has more tax slabs with generally lower rates.
Minimal Exemptions: It disallows most common exemptions and deductions, such as those under Section 80C, 80D, HRA, and LTA.
Standard Deduction: A standard deduction of ₹75,000 is available for salaried individuals and pensioners.
Higher Rebate: A significant tax rebate under Section 87A makes income up to ₹12 lakh effectively tax-free.

2. The Old Tax Regime

The familiar “old” regime is based on the principle of “higher tax rates, but with many exemptions and deductions.” It encourages tax-saving investments and expenses.

Key Features:

Higher Tax Rates: The slab rates are higher, with a 20% tax rate starting at ₹5 lakh and the highest rate of 30% starting at ₹10 lakh.
Extensive Deductions: It allows a wide range of deductions and exemptions, which can substantially reduce your taxable income.

Old vs. New: A Side-by-Side Comparison

To help you decide, here is a detailed breakdown of the two regimes for the Financial Year 2025-26 (Assessment Year 2026-27).

Feature	Old Tax Regime	New Tax Regime (Default)
Basic Exemption Limit	Up to ₹2.5 lakh (for individuals below 60)	Up to ₹4 lakh
Tax Slabs	₹2.5L-₹5L: 5% ₹5L-₹10L: 20% > ₹10L: 30%	₹4L-₹8L: 5% ₹8L-₹12L: 10% ₹12L-₹16L: 15% ₹16L-₹20L: 20% > ₹20L: 30%
Standard Deduction	₹50,000 for salaried individuals	₹75,000 for salaried individuals
Rebate u/s 87A	Tax-free income up to ₹5 lakh	Tax-free income up to ₹12 lakh
Deductions	Allows a wide range of deductions, including: – Sec 80C: Investments up to ₹1.5 lakh (PPF, EPF, ELSS, life insurance, etc.) – Sec 80D: Health insurance premiums – Sec 24(b): Home loan interest	Mostly disallowed. Only a few specific deductions like employer’s contribution to NPS are allowed.

How to Make the Right Choice: The Decision Framework

Your choice depends entirely on your financial behavior and investment habits. There is no one-size-fits-all answer.

Do you have significant deductions?
- If you have a home loan, pay a high rent, and make substantial investments under Section 80C and 80D, the Old Regime will likely result in a lower tax liability. The ability to claim these deductions often outweighs the lower tax rates of the new regime.
Are your deductions limited or non-existent?
- If you don’t have a home loan, live in your own home, or prefer not to lock your money in long-term investments, the New Regime is probably the better choice. Its lower tax rates and higher standard deduction will provide more tax savings and give you greater control over your finances.
Use a Tax Calculator.
- The most accurate way to decide is to calculate your tax liability under both regimes. Use the official income tax portal’s tax calculator or a reliable online tool. This will give you a clear, numbers-based comparison.

Sample Case: A Salaried Professional’s Dilemma

The Problem: Meet Rohan, a young salaried professional in Bengaluru. This year, the new default tax regime left him completely confused. He had invested in ELSS and was paying a home loan EMI, but he wasn’t sure if the old regime’s deductions would save him more tax than the new regime’s lower rates. With the filing deadline approaching, he was anxious about making a costly mistake.

The Kanoons Solution: Rohan contacted Kanoons, and our tax experts immediately set up a consultation. We conducted a detailed, side-by-side analysis of his income, investments, and expenses under both tax regimes.
