The old tax regime has been in place for decades and allows taxpayers to claim a wide range of deductions and exemptions. These include Section 80C investments up to Rs. 1.5 lakh (PPF, ELSS, life insurance premiums), HRA exemption for rent paid, NPS contribution under Section 80CCD, home loan interest deduction under Section 24, standard deduction of Rs. 50,000, and many more.
The old regime tax slabs for FY 2025-26 are: income up to Rs. 2.5 lakh is exempt, Rs. 2.5 lakh to Rs. 5 lakh is taxed at 5%, Rs. 5 lakh to Rs. 10 lakh at 20%, and above Rs. 10 lakh at 30%. If your taxable income after all deductions is Rs. 5 lakh or below, you get a full rebate under Section 87A and pay zero tax.
What is the New Tax Regime?
The new tax regime was introduced in FY 2020-21 and has been made the default regime from FY 2023-24. It offers lower tax rates but allows very few deductions — only a standard deduction of Rs. 75,000 is available. All other exemptions like HRA, 80C, NPS, and home loan interest are not allowed.
The new regime slabs for FY 2025-26 are more granular: up to Rs. 3 lakh is exempt, Rs. 3 lakh to Rs. 7 lakh at 5%, Rs. 7 lakh to Rs. 10 lakh at 10%, Rs. 10 lakh to Rs. 12 lakh at 15%, Rs. 12 lakh to Rs. 15 lakh at 20%, and above Rs. 15 lakh at 30%. The rebate under Section 87A applies if taxable income is Rs. 7 lakh or below, making income up to Rs. 7.75 lakh effectively tax-free.

Which Regime is Better? — With Examples
The answer depends entirely on your deductions. Here are three common scenarios:
Scenario 1 — Income Rs. 8 lakh, Deductions Rs. 2.5 lakh
Old regime taxable income: Rs. 5.5 lakh. Tax: Rs. 25,000 + 4% cess = Rs. 26,000. New regime taxable income: Rs. 7.25 lakh. Tax: Rs. 22,500 + 4% cess = Rs. 23,400.New regime saves Rs. 2,600.
Scenario 2 — Income Rs. 12 lakh, Deductions Rs. 3.5 lakh
Old regime taxable income: Rs. 8.5 lakh. Tax: Rs. 82,500 + 4% cess = Rs. 85,800. New regime taxable income: Rs. 11.25 lakh. Tax: Rs. 95,000 + 4% cess = Rs. 98,800.Old regime saves Rs. 13,000.
Scenario 3 — Income Rs. 15 lakh, Deductions Rs. 1.5 lakh
Old regime taxable income: Rs. 13.5 lakh. Tax: Rs. 2,12,500 + 4% cess = Rs. 2,21,000. New regime taxable income: Rs. 14.25 lakh. Tax: Rs. 1,72,500 + 4% cess = Rs. 1,79,400.New regime saves Rs. 41,600.
General Rule of Thumb
As a general rule, if your total deductions (80C + HRA + NPS + home loan interest + others) exceed Rs. 3.75 lakh for income up to Rs. 15 lakh, the old regime is likely better. If your deductions are below Rs. 3.75 lakh, the new regime usually saves more tax. However this breakeven point varies with income level, so always calculate both using our income tax calculator before deciding.
Can You Switch Between Regimes?
Salaried employees can switch between old and new regime every year at the time of filing their ITR. However, taxpayers with business income can switch only once from new to old regime. Since the new regime is now the default, you need to actively opt for the old regime when filing your ITR if you want to claim deductions.
