Learn about the Indian tax system, tax calculation methods, and important concepts to help you make informed financial decisions.
The Indian Tax System: An Overview
The Indian income tax system is governed by the Income Tax Act, 1961, and is administered by the Income Tax Department under the Department of Revenue, Ministry of Finance. The tax system in India follows a progressive structure, where higher income levels are taxed at higher rates.
Indian Tax System Structure
The Indian financial year runs from April 1 to March 31. Income earned during this period is assessed for tax in the following assessment year. For example, income earned during the financial year 2024-25 (April 1, 2024, to March 31, 2025) will be assessed for tax in the assessment year 2025-26.

How Income Tax is Calculated
Income tax calculation in India follows a step-by-step process. The method differs slightly between the old and new tax regimes due to the availability of deductions and exemptions.
Tax Calculation Process
Calculate Gross Total Income
Add income from all sources: Salary, House Property, Business/Profession, Capital Gains, Other Sources
Apply Exemptions
Subtract exempt income like HRA, LTA (only in old regime)
Apply Deductions
Subtract eligible deductions under Chapter VI-A (only in old regime)
Calculate Taxable Income
Gross Total Income - Exemptions - Deductions
Apply Tax Slabs
Apply progressive tax rates to different income slabs
Add Cess
Add Health & Education Cess (4% of tax amount)
Final Tax Liability
Tax on Slabs + Cess
Detailed Example: Tax Calculation
Let's understand the tax calculation process with a practical example for a salaried individual aged 35 years with the following income and deductions:
Income
- Basic Salary: ₹8,00,000
- HRA Received: ₹2,40,000
- Other Allowances: ₹1,60,000
- Interest Income: ₹20,000
Deductions & Exemptions
- HRA Exemption: ₹1,80,000
- Section 80C: ₹1,50,000
- Section 80D: ₹25,000
- Standard Deduction: ₹50,000
Old Tax Regime Calculation
- On first ₹2,50,000: ₹0
- On next ₹2,50,000 (₹2,50,001 to ₹5,00,000) @ 5%: ₹12,500
- On next ₹3,15,000 (₹5,00,001 to ₹8,15,000) @ 20%: ₹63,000
New Tax Regime Calculation
- On first ₹4,00,000: ₹0
- On next ₹4,00,000 (₹4,00,001 to ₹8,00,000) @ 5%: ₹20,000
- On next ₹4,00,000 (₹8,00,001 to ₹12,00,000) @ 10%: ₹40,000
- On next ₹20,000 (₹12,00,001 to ₹12,20,000) @ 15%: ₹3,000
Conclusion
In this example, the New Tax Regime is more beneficial, resulting in a tax saving of ₹13,000 compared to the Old Tax Regime.
Types of Income Under Indian Tax Law
The Income Tax Act categorizes income into five heads for the purpose of calculation and taxation:
Five Heads of Income
Income from Salary
Includes basic salary, allowances, perquisites, and retirement benefits received from an employer.
Income from House Property
Rental income from properties, including deemed rental income from self-occupied property.
Income from Business/Profession
Profits and gains from business or professional activities.
Income from Capital Gains
Profits from the sale of capital assets like property, shares, or mutual funds.
Income from Other Sources
Income that doesn't fall under the other four heads, like interest, dividends, lottery winnings, etc.
Important Note on Income Aggregation
Income from all five heads is aggregated to arrive at the Gross Total Income. However, each head has its own set of rules for calculating taxable income, including specific deductions and exemptions.
For example, under "Income from House Property," you can claim a standard deduction of 30% of the annual value, as well as interest paid on home loans. Similarly, under "Income from Business/Profession," you can claim various business expenses.
Common Deductions and Exemptions
Deductions and exemptions help reduce your taxable income, thereby lowering your tax liability. These are primarily available under the Old Tax Regime.
Major Deductions Under Chapter VI-A
Section 80C (₹1.5 Lakh)
Section 80D (₹25K-₹1L)
Section 24 (₹2 Lakh)
Section 80E (No Limit)
Section 80G (50-100%)
Section 80TTB (₹50K)
