How Income Tax is Calculated
This free online income tax calculator for India helps you calculate your income tax liability for Financial Year 2024-25 (Assessment Year 2025-26). The calculator supports both Old and New tax regimes and calculates tax based on standard deduction, progressive tax slabs, Section 87A rebate, and health & education cess. Understanding how income tax is calculated helps you plan your finances better and know exactly how much tax you need to pay.
Tax Calculation Steps:
- Standard Deduction = ₹50,000 (applied to both Old and New regimes)
- Taxable Income = Annual Gross Income - Standard Deduction
- Age group determines the non-taxable base before slabs apply:
- Below 60 years: non-taxable up to ₹2.5L
- Senior Citizen (60-80): non-taxable up to ₹3.0L
- Super Senior Citizen (80+): non-taxable up to ₹5.0L
- Income Tax is calculated using progressive tax slabs based on regime and age
- Section 87A Rebate is applied if eligible:
- New Regime: If Taxable Income ≤ ₹7,00,000 → Income Tax = 0 (rebate up to ₹25,000)
- Old Regime: If Taxable Income ≤ ₹5,00,000 → Income Tax = 0 (rebate up to ₹12,500)
- Health & Education Cess = 4% of Income Tax (only if Income Tax > 0)
- Total Tax Payable = Income Tax + Cess
- Net Income After Tax (Tax Impact Only) = Annual Gross Income - Total Tax Payable
New Regime Tax Slabs (FY 2024-25):
- ₹0 - ₹3,00,000: 0%
- ₹3,00,001 - ₹6,00,000: 5%

- ₹9,00,001 - ₹12,00,000: 15%
- ₹12,00,001 - ₹15,00,000: 20%
- Above ₹15,00,000: 30%
Old Regime Tax Slabs (FY 2024-25):
Below 60 years:
- ₹0 - ₹2,50,000: 0%

Important Note: Standard deduction reduces taxable income for tax calculation but does not reduce your actual salary received. The standard deduction is a tax benefit that lowers your taxable income, thereby reducing your tax liability, but it does not affect the actual amount you receive in your bank account.
Example Calculations
Example 1: Section 87A Rebate - Old Regime
Let's calculate tax for an individual with the following details:
- Annual Gross Income: ₹5,50,000
- Age Group: Below 60 years
- Tax Regime: Old Regime
Using the tax calculation formula:
- Standard Deduction = ₹50,000
- Taxable Income = ₹5,50,000 - ₹50,000 = ₹5,00,000
- Section 87A Rebate Check: Taxable Income (₹5,00,000) ≤ ₹5,00,000 → Rebate applies
- Income Tax (Before Cess) = ₹0 (rebate applied)
- Health & Education Cess (4%) = ₹0 (since Income Tax = 0)
- Total Tax Payable = ₹0
- Net Income After Tax (Tax Impact Only) = ₹5,50,000 - ₹0 = ₹5,50,000
Example 2: Section 87A Rebate - New Regime (Zero Tax Example)
Let's calculate tax for an individual with the following details:
- Annual Gross Income: ₹7,50,000
- Age Group: Below 60 years
- Tax Regime: New Regime
Using the tax calculation formula:
- Standard Deduction = ₹50,000
- Taxable Income = ₹7,50,000 - ₹50,000 = ₹7,00,000
- Section 87A Rebate Check: Taxable Income (₹7,00,000) ≤ ₹7,00,000 → Rebate applies
- Income Tax (Before Cess) = ₹0 (rebate applied - Section 87A eliminates tax completely)
- Health & Education Cess (4%) = ₹0 (since Income Tax = 0)
- Total Tax Payable = ₹0
- Net Income After Tax (Tax Impact Only) = ₹7,50,000 - ₹0 = ₹7,50,000
Key Takeaway: With Gross Income of ₹7,50,000 under New Regime, your taxable income after standard deduction is exactly ₹7,00,000, which qualifies for Section 87A rebate. This means Total Tax Payable = ₹0, demonstrating the significant tax benefit of the rebate provision.
Example 2D: Section 87A Rebate - New Regime (Gross Income ₹7,00,000 → Tax ₹0)
Explicit rebate example: Gross Income ₹7,00,000 (New Regime) → Tax ₹0 due to Section 87A
- Annual Gross Income: ₹7,00,000
- Age Group: Below 60 years
- Tax Regime: New Regime
- Gross Income ₹7,00,000 - Standard Deduction ₹50,000 = Taxable Income ₹6,50,000
- Taxable Income ₹6,50,000 ≤ ₹7,00,000 → Section 87A Rebate applies
- Income Tax (Before Cess) = ₹0
- Health & Education Cess (4%) = ₹0
- Result: Total Tax Payable = ₹0
Key Takeaway: With Gross Income of ₹7,00,000 under New Regime, after standard deduction of ₹50,000, your taxable income becomes ₹6,50,000, which qualifies for Section 87A rebate. This means you pay zero tax, demonstrating the significant benefit of the rebate provision. This builds huge trust in the calculator.
Example 3: Tax Calculation with Cess
Let's calculate tax for an individual with the following details:
- Annual Gross Income: ₹12,00,000
- Age Group: Below 60 years
- Tax Regime: New Regime
Using the tax calculation formula:
- Standard Deduction = ₹50,000
- Taxable Income = ₹12,00,000 - ₹50,000 = ₹11,50,000
- Section 87A Rebate Check: Taxable Income (₹11,50,000) > ₹7,00,000 → Rebate does not apply
- Tax Calculation (New Regime):
- Tax on first ₹3,00,000 = ₹0
- Tax on next ₹3,00,000 (₹3L to ₹6L) = ₹3,00,000 × 5% = ₹15,000
- Tax on next ₹3,00,000 (₹6L to ₹9L) = ₹3,00,000 × 10% = ₹30,000
- Tax on next ₹2,50,000 (₹9L to ₹11.5L) = ₹2,50,000 × 15% = ₹37,500
- Total Income Tax (Before Cess) = ₹0 + ₹15,000 + ₹30,000 + ₹37,500 = ₹82,500
- Health & Education Cess (4%) = ₹82,500 × 4% = ₹3,300
- Total Tax Payable = ₹82,500 + ₹3,300 = ₹85,800
- Net Income After Tax (Tax Impact Only) = ₹12,00,000 - ₹85,800 = ₹11,14,200
Quick Answers

Tax is calculated on taxable income (after deductions and exemptions) using the applicable slab rates. Health and education cess (4%) is added on the tax amount.
What is the difference between Old and New tax regime?
The Old Regime allows various deductions (e.g. 80C, 80D, HRA) but has higher slab rates. The New Regime has lower rates but only a standard deduction of ₹50,000.
What is standard deduction?
Standard deduction is a flat deduction from salary income. For FY 2025-26, it is ₹75,000 (salaried and pensioners) under the New Regime and ₹50,000 under the Old Regime.
What is Section 87A rebate?
Section 87A gives a rebate so that individuals with taxable income up to a threshold (e.g. ₹7 lakh under New Regime) may pay no tax. The rebate is applied before cess.
When do I need to choose Old vs New regime?
Salaried employees declare their choice to the employer; others can choose while filing the return. The choice can be made each financial year.
Frequently Asked Questions
What is Section 87A rebate and how does it work?
Section 87A rebate is a tax relief provision that reduces or eliminates income tax for individuals with lower taxable income. For FY 2024-25, under the New Regime, if your taxable income is ₹7,00,000 or less, you can claim a rebate of up to ₹25,000 (or 100% of your tax liability, whichever is less), effectively making your tax zero. Under the Old Regime, if your taxable income is ₹5,00,000 or less, you can claim a rebate of up to ₹12,500 (or 100% of your tax liability, whichever is less). The rebate is applied before calculating health & education cess, and if the rebate reduces your tax to zero, no cess is applicable.
What is the difference between Old and New tax regimes?
The Old Regime allows various deductions and exemptions like Section 80C, 80D, HRA exemption, etc., but has higher tax rates. The New Regime offers lower tax rates but with limited deductions (only standard deduction of ₹50,000). The New Regime is generally beneficial for individuals with fewer investments and deductions. Both regimes have the same standard deduction of ₹50,000. The choice between regimes depends on your individual circumstances, investments, and deductions. You can switch between regimes each financial year.
How does age affect income tax calculation?
Age group determines the non-taxable base (basic exemption limit) before tax slabs apply. For individuals below 60 years, the first ₹2,50,000 is non-taxable under Old Regime. For Senior Citizens (60-80 years), the first ₹3,00,000 is non-taxable. For Super Senior Citizens (80+ years), the first ₹5,00,000 is non-taxable. This higher exemption limit for senior citizens reduces their tax liability. Under the New Regime, age does not affect the tax slabs, but the basic exemption limit remains the same for all age groups (first ₹3,00,000 is non-taxable).
What is Health and Education Cess?
Health and Education Cess is an additional 4% tax levied on the total income tax amount. It was introduced to fund health and education initiatives in India. The cess is calculated after applying all tax slabs and rebates. For example, if your income tax is ₹50,000, the cess would be ₹2,000 (4% of ₹50,000), making your total tax liability ₹52,000. If your income tax becomes zero after Section 87A rebate, no cess is applicable.
Which tax regime should I choose - Old or New?
The choice depends on your deductions and exemptions. If you have significant investments (80C, 80D), home loan interest, HRA exemptions, and other deductions exceeding ₹3-4 lakhs, the Old Regime may be more beneficial. If you have minimal deductions or investments, the New Regime with its lower tax rates is usually better. Generally, for income up to ₹7-8 lakhs with few deductions, the New Regime is advantageous. You can switch between regimes each year (if you don't have business income).
What deductions are available under Section 80C?
Section 80C allows deductions up to ₹1,50,000 per year for investments and expenses including EPF (Employee Provident Fund), PPF (Public Provident Fund), ELSS (Equity Linked Savings Scheme), life insurance premiums, home loan principal repayment, children's tuition fees, NSC (National Savings Certificate), and 5-year fixed deposits. Note that 80C deductions are available only under the Old Regime, not the New Regime. This calculator focuses on standard deduction only; for detailed 80C planning, consult a tax professional.
