What is Income Tax?
Income tax is a direct tax that the Government of India collects from individuals and organisations on the income they earn in a financial year. The money collected is used to fund public services — roads, schools, hospitals, defence, and government schemes.
It is governed by the Income Tax Act, 1961 and administered by the Central Board of Direct Taxes (CBDT) under the Ministry of Finance.
💡 Simple way to think about it: If you earn money in India — from salary, business, property, or investments — the government takes a small percentage as tax. That percentage depends on how much you earn.
Who Must Pay Income Tax?
In India, income tax applies to the following:
- Individuals — salaried employees, freelancers, self-employed
- Hindu Undivided Families (HUF)
- Companies and firms
- Partnership firms and LLPs
- Trusts and associations
As an individual, you are required to pay income tax if your gross annual income exceeds the basic exemption limit — ₹2.5 lakh under the old regime or ₹3 lakh under the new regime.
✅ Good news: If your total income is below ₹7 lakh (new regime) or ₹5 lakh (old regime), you pay zero tax after the Section 87A rebate.
Types of Income That Are Taxed
Under the Income Tax Act, income is divided into 5 heads:
| Head of Income | Examples |
|---|---|
| Salary | Wages, basic pay, HRA, bonuses, allowances |
| House Property | Rent received from property owned |
| Business / Profession | Income from freelancing, trade, or profession |
| Capital Gains | Profit from selling shares, mutual funds, property |
| Other Sources | Bank interest, dividends, lottery winnings, gifts |
How is Income Tax Calculated?
Tax calculation follows a simple 4-step process:
- Calculate Gross Total Income — Add income from all 5 heads above.
- Subtract Deductions — Apply 80C, 80D, HRA, standard deduction, etc. (old regime only).
- Apply Tax Slabs — Apply the percentage rates on your taxable income slab-by-slab.
- Add Cess — Add 4% Health & Education Cess on the final tax amount.
⚠️ Don’t forget surcharge: If your income exceeds ₹50 lakh, an additional surcharge applies on top of the base tax.

Quick FAQs
Is income tax the same as TDS?
No. TDS (Tax Deducted at Source) is tax deducted by your employer or bank before paying you. It is part of your income tax liability — not a separate tax. When you file your ITR, TDS is adjusted against your total tax due.
Do I need to file a return if I have no tax to pay?
Yes, if your gross income exceeds the basic exemption limit, you must file a return even if your final tax is zero after deductions and rebates.
What happens if I don’t pay income tax?
Non-payment or late filing attracts penalties under Section 234A (interest), Section 234B (advance tax default), and Section 271 (concealment penalty). In serious cases, prosecution under Section 276C is possible.
