Income Tax Calculator – Compare Old vs New Regimes Side-by-Side
Understanding personal taxation in India is a key component of wealth management. In recent budgets, the Ministry of Finance has introduced substantial modifications to make tax compliance simpler and lower the tax liability for middle-income segments. Taxpayers are faced with a crucial decision: selecting between the **Old Tax Regime**, which allows multiple investment exemptions, and the **New Tax Regime**, which features lower tax slabs but eliminates deductions.
For the financial year (FY) 2025-26, the New Tax Regime is the default choice and offers a standard deduction of ₹75,000 for salaried employees. Furthermore, under Section 87A, individuals earning up to ₹12 Lakhs can qualify for tax rebates, rendering their net tax liability zero.
Our online **Income Tax Calculator** provides an interactive, side-by-side comparison of your tax liabilities. By inputting your annual income, deductions (like Section 80C, 80D, and HRA), and home loan interest, you can instantly compare your options. The tool is free, secure, and helps you optimize your tax planning for both FY 2024-25 and FY 2025-26.

Section 87A rebate provides tax relief to taxpayers. For FY 2025-26 (New Regime), taxpayers with taxable income up to ₹12 Lakhs are eligible for rebate up to ₹60,000, effectively reducing tax to zero. For FY 2024-25, the zero-tax rebate limit was ₹7 Lakhs.
How do the Old and New regimes differ?
The New Regime offers lower tax slab rates but does not allow major exemptions (like 80C, 80D, HRA). The Old Regime has higher slab rates but allows deductions for investments, insurance, home loans, and rents, which help reduce taxable income.
Can I choose which tax regime to file under?
Yes, salaried individuals can choose between the Old and New tax regimes every year at the time of filing their Income Tax Return (ITR), provided they do not have business or professional income. Business owners can only switch regimes once in a lifetime.
What deductions are allowed under the New Tax Regime?
The New Tax Regime allows very few deductions. Key permitted allowances include the standard deduction of ₹75,000 (increased in Budget 2024), employer contributions to NPS under Section 80CCD(2), and family pension deductions.
What is the limit of Section 80C under the Old Tax Regime?
Under the Old Tax Regime, Section 80C allows a maximum deduction of ₹1.5 Lakhs per financial year. This includes investments in PPF, EPF, ELSS, NPS, tax-saving FDs, life insurance premiums, school tuition fees, and home loan principal repayments.
How is the Health and Education Cess calculated?
A flat 4% Health and Education Cess is calculated on the cumulative sum of your calculated income tax and applicable surcharge. This cess is mandatory under both the Old and New Tax Regimes.
What are the surcharge rates for high-income earners?
Surcharges are levied on taxpayers with incomes exceeding ₹50 Lakhs. Under the New Tax Regime, the maximum surcharge is capped at 25% (for income above ₹5 Crores), while under the Old Tax Regime, the maximum surcharge remains at 37%.
Does the calculator include Capital Gains tax?
Our basic tax calculator is optimized for salary, business, and house property income. Capital gains (short-term and long-term) have specialized tax rates (like 12.5% for LTCG on equities) and should be computed separately.
What happens if I don't select a regime at the time of filing?
The New Tax Regime is the default option. If you do not actively opt out of it and file Form 10-IEA (where applicable) to select the Old Regime, your ITR will automatically be processed under the New Tax Regime rules.
