Comprehensive Guide: How to Calculate Income Tax in India (FY 2023-24) with Example PDF
Understanding how to calculate income tax in India is essential for every taxpayer to ensure compliance and optimize tax savings. The Indian income tax system operates under two regimes – the old tax regime with deductions and the new concessional tax regime with lower rates. This guide provides a step-by-step explanation with practical examples and comparisons.
1. Understanding Tax Regimes in India
India currently offers two tax regimes for individual taxpayers:
- New Tax Regime (Default since FY 2023-24): Introduced in Budget 2020 and made default in Budget 2023, this regime offers lower tax rates but disallows most deductions and exemptions (except standard deduction of ₹50,000 and a few others).
- Old Tax Regime: The traditional system with higher tax rates but allows for various deductions under Sections 80C, 80D, HRA, etc. Taxpayers can choose this regime if it results in lower tax liability.

4. Practical Example with PDF Calculation
Let’s consider Mr. Sharma, a 35-year-old salaried individual in Delhi with:
- Annual Salary: ₹12,00,000
- HRA Received: ₹3,00,000
- Annual Rent Paid: ₹2,40,000
- Section 80C Investments: ₹1,50,000
- Health Insurance Premium: ₹25,000
Calculation Under Old Regime:
- Gross Income: ₹12,00,000
- Deductions:
- Standard Deduction: ₹50,000
- Section 80C: ₹1,50,000
- Section 80D: ₹25,000
- HRA Exemption: ₹2,00,000 (minimum of HRA received, 50% of salary, rent paid minus 10% of salary)
- Taxable Income: ₹12,00,000 – (₹50,000 + ₹1,50,000 + ₹25,000 + ₹2,00,000) = ₹7,75,000
- Income Tax:
- Up to ₹2,50,000: Nil
- ₹2,50,001 – ₹5,00,000: ₹12,500 (5%)
- ₹5,00,001 – ₹7,75,000: ₹55,000 (20%)
- Total: ₹67,500
- Cess: 4% of ₹67,500 = ₹2,700
- Total Tax: ₹67,500 + ₹2,700 = ₹70,200
Calculation Under New Regime:
- Gross Income: ₹12,00,000
- Standard Deduction: ₹50,000
- Taxable Income: ₹11,50,000
- Income Tax:
- Up to ₹3,00,000: Nil
- ₹3,00,001 – ₹6,00,000: ₹15,000 (5%)
- ₹6,00,001 – ₹9,00,000: ₹30,000 (10%)
- ₹9,00,001 – ₹11,50,000: ₹37,500 (15%)
- Total: ₹82,500
- Rebate: ₹7,00,000 limit doesn’t apply (income > ₹7,00,000)
- Cess: 4% of ₹82,500 = ₹3,300
- Total Tax: ₹82,500 + ₹3,300 = ₹85,800
In this case, the old regime is more beneficial (₹70,200 vs ₹85,800). You can download a sample calculation PDF from the Income Tax Department’s e-filing portal.
