What is Income Tax?
Income tax is a direct tax imposed by the central government on the income earned by individuals and entities during a financial year. It is a key source of government revenue, which is utilized for infrastructure development, healthcare, education, agricultural subsidies, and various welfare schemes.
Taxes in India are broadly classified into two categories:
-
Direct Taxes -These are levied directly on an individual's or entity's income or wealth. Income tax is a prime example of a direct tax.
​​
-
Indirect Taxes - are imposed on goods and services and collected by intermediaries (such as sellers) on behalf of the government. The Goods and Services Tax (GST) is a notable indirect tax.
Income tax is crucial to the country's economic growth, ensuring financial stability and funding essential public services.
​
Direct taxes can be characterized as follows:
​
Income tax
​
This is the income tax paid by an individual, a Hindu Undivided Family, or any taxpayer other than a corporation. The legislation specifies the rate at which such income is taxed.
​
Corporate Tax
​
This is the tax that corporations pay on their profits. Again, India's income tax rules have imposed a certain tax rate on corporations.
Who Needs to Pay Income Tax in India? – Types of Taxpayers
Under the Income Tax Act, 1961, any individual or entity earning taxable income in India is required to file income tax returns. The individual or entity whose income is subject to taxation is referred to as an assessee.
Different categories of taxpayers are subject to different tax rules based on their classification.
Categories of Taxpayers who should file ITR are:
1. Individuals
2. Hindu Undivided Family (HUF)
3. Firms
4. Companies
5. Association of Persons (AOP)
6. Body of Individuals (BOI)
7. Local Authority
8. Artificial Juridical Person
Residential Status and Tax Liability
In India, taxation is determined based on a person’s residential status, not just their citizenship. Residential status is classified into:
• Resident
• Resident but Not Ordinarily Resident (RNOR)
• Non-Resident (NR)
A person’s number of days of stay in India within a financial year determines their residential status.
​
-
Residents must pay tax on their global income (both income earned in India and income earned abroad).
-
Non-resident Indians (NRIs) are only liable to pay income tax earned or accrued in India.
The residential status must be determined separately for each financial year.
Types of Income – The 5 Heads of Income
Anyone earning or receiving income in India is liable to pay income tax, whether they are a resident or a non-resident. To streamline taxation, the Income Tax Department categorizes income into five primary heads:​
Source of Income | Nature of Income Covered |
---|---|
Other Sources Income | Savings account interest, fixed deposit interest, lottery winnings, etc. |
Capital Gains Income | Profits from the sale of assets like shares, property, or mutual funds. |
Business or Profession Income | Income earned by self-employed individuals, businesses, freelancers, and contractors, as well as professionals such as life insurance agents, chartered accountants, doctors, lawyers, and private tutors, falls under this taxable category. |
House Property Income | Rental income from owned property. |
Salary Income | Salary and pension income. |
Tax Deductions and Tax-Saving Instruments
Taxpayers can reduce their taxable income by investing in tax-saving instruments under Sections 80C to 80U of the Income Tax Act. These deductions are applicable only under the Old Tax Regime.

To encourage adoption, Budget 2023 made the new tax regime the default option.

This rebate applies to resident individuals whose total income (after deductions under Chapter VI-A, such as Sections 80C, 80D, and 80U) does not exceed a specified threshold.
