An India income tax calculator helps you compare the Old and New tax regimes side by side for FY 2025-26 (AY 2026-27). India offers two tax regimes — the New regime with lower rates but fewer deductions, and the Old regime with higher rates but extensive deduction options under sections 80C, 80D, HRA, and more. This tool calculates tax, surcharge, cess, and take-home pay under both regimes so you can choose the one that saves you more.

How to Use This India Income Tax Calculator
Choosing between the Old and New tax regimes is one of the most important financial decisions for Indian taxpayers each year. The New regime, which became the default from FY 2023-24, offers lower tax rates spread across more slabs but removes most deductions and exemptions. The Old regime retains higher base rates but allows you to claim deductions under sections 80C, 80D, HRA, NPS, and home loan interest — which can substantially reduce your taxable income. This India income tax calculator computes your liability under both regimes simultaneously so you can make an informed choice.
Step 1: Enter Your Gross Annual Salary
Start by entering your total annual income (CTC or gross salary) in the input field. This should be your income before any deductions or exemptions. The calculator uses this as the base to compute taxable income under both regimes. For FY 2025-26, both regimes apply a standard deduction — Rs 75,000 for the New regime and Rs 50,000 for the Old regime — which is automatically deducted from your gross salary.
Step 2: Enter Old Regime Deductions
Fill in the deductions that apply to you under the Old regime. Section 80C covers investments up to Rs 1,50,000 in PPF, ELSS, EPF, life insurance, and tuition fees. Section 80D covers health insurance premiums (Rs 25,000 for self, Rs 50,000 if senior citizen, plus additional for parents). Enter your HRA exemption amount, NPS contribution under 80CCD(1B) (up to Rs 50,000), home loan interest under Section 24 (up to Rs 2,00,000), and any other deductions. These fields only affect the Old regime calculation — the New regime ignores them.
Step 3: Compare Both Regimes
Click "Compare Tax Regimes" to see results side by side. Each regime card shows the complete tax computation: gross salary, deductions applied, taxable income, base income tax, Section 87A rebate (if applicable), surcharge, Health and Education Cess (4%), total tax payable, annual and monthly take-home pay, and effective tax rate. The recommendation banner at the top tells you which regime saves you more tax and by exactly how much.
Understanding the Section 87A Rebate
Under the New regime for FY 2025-26, if your total income (after standard deduction) does not exceed Rs 12,00,000, you are eligible for a full tax rebate under Section 87A — meaning you pay zero tax. With the Rs 75,000 standard deduction, this effectively makes gross income up to Rs 12,75,000 tax-free under the New regime. Under the Old regime, the 87A rebate limit is Rs 5,00,000 of taxable income. The calculator automatically applies the correct rebate for each regime.
New Regime Tax Slabs for FY 2025-26
The New regime slabs are: Nil on the first Rs 4,00,000; 5% on Rs 4,00,001 to Rs 8,00,000; 10% on Rs 8,00,001 to Rs 12,00,000; 15% on Rs 12,00,001 to Rs 16,00,000; 20% on Rs 16,00,001 to Rs 20,00,000; 25% on Rs 20,00,001 to Rs 24,00,000; and 30% above Rs 24,00,000. These rates are lower than the Old regime, which charges 5% from Rs 2,50,001 and jumps to 20% from Rs 5,00,001 and 30% above Rs 10,00,000.

What is the difference between Old and New tax regime in India?
The New regime (default from FY 2023-24) offers lower tax rates across more slabs but does not allow most deductions like 80C, 80D, or HRA. The Old regime has higher base rates but lets you claim deductions that can significantly reduce taxable income. Which is better depends on your total deductions.
What is the rebate under Section 87A in the New regime?
Under the New regime for FY 2025-26, if your total income after standard deduction does not exceed Rs 12,00,000, you pay zero tax thanks to the Section 87A rebate. With the Rs 75,000 standard deduction, this means gross salary up to Rs 12,75,000 is effectively tax-free.
Which tax regime is better for salaried employees?
It depends on your deductions. If your total deductions under 80C, 80D, HRA, NPS, and home loan interest exceed approximately Rs 3-4 lakh, the Old regime may save you more tax. If you have few deductions, the New regime with its lower rates is usually better. Use this calculator to compare both side by side.
How is surcharge calculated on Indian income tax?
Surcharge is an additional tax on the income tax amount. For income between Rs 50 lakh and Rs 1 crore, the surcharge is 10%. Between Rs 1-2 crore it is 15%, Rs 2-5 crore is 25%, and above Rs 5 crore is 37% (Old regime) or 25% max (New regime). The 4% Health and Education Cess is then applied on tax plus surcharge.
What deductions are available under the Old tax regime?
The Old regime allows deductions under Section 80C (up to Rs 1,50,000 for PPF, ELSS, life insurance, etc.), 80D (health insurance premiums), HRA exemption, NPS contribution under 80CCD(1B) (up to Rs 50,000), and home loan interest under Section 24 (up to Rs 2,00,000). These can substantially reduce your taxable income.
Does this calculator include Health and Education Cess?
Yes, the calculator applies the 4% Health and Education Cess on top of the income tax and surcharge amount, just as the Indian tax system requires. The total tax shown includes base tax, applicable surcharge, and the 4% cess.
