5 Heads of Income Under the Income Tax Act

If you have ever filed an income tax return, you have already interacted with the concept of the five heads of income, even if you did not consciously think about it.

The Income Tax Act does not simply look at how much money you earn in a year. It looks at where that money came from. A salary, rent from property, profit from selling shares, and interest from a fixed deposit may all increase your bank balance, but the tax laws treat them differently.

That is why the Income Tax Act divides income into five specific categories. These are known as the heads of income, and they determine how tax is calculated, which deductions apply, and how you report the income while filing your return.

Most taxpayers in India typically deal with two or three of these categories. If you are employed, you will report income from salary. If you have investments, you might have income from capital gains or interest income under income from other sources. Property owners deal with income from house property, while business owners report profits and gains from business or profession.

Understanding these heads is not just about filing returns correctly. It helps you structure your finances better and avoid errors while declaring income under the Income Tax Act.

Why Are There 5 Heads of Income?

The Income Tax Act is built around a structured approach to taxation. Rather than applying one rule to all types of income, the law categorizes earnings into defined heads so that each category can have its own tax calculation method. This classification comes from Section 14 of the Income Tax Act, which states that all taxable income must be grouped under five specific heads before computing total income. The five heads exist mainly for three reasons.

1. Different types of income behave differently

Salary income is predictable and usually taxed through TDS by the employer. Business income fluctuates and involves expenses. Capital gains arise from selling assets and depend on the holding period.

If the Income Tax Act taxed everything the same way, the system would ignore these differences.

2. Deductions vary across income types

Certain deductions apply only to specific heads.

For example:

• Interest deduction for home loans applies to income from house property
• Business expenses reduce income from a business or profession
• Standard deduction applies to income from salary

Without classification, applying these deductions correctly would become messy.

3. It simplifies tax administration

From the government’s perspective, dividing income into heads helps track how taxpayers earn money. When you file your return, income is reported in specific schedules:

• Schedule S – Income from salary
• Schedule HP – Income from house property
• Schedule BP – Business or profession  income
• Schedule CG – Income from capital gains
• Schedule OS – Income from other sources

This structure makes tax reporting more consistent. Before calculating tax liability, you must organise your income under these five heads defined by the Income Tax Act.

1. Income From Salary

For many, income from salary is the primary source of earnings. If you are an employee drawing a salary, that money is taxed under this head.

Under the old 1961 Act, sections 15–17 defined salary income; under the Income Tax Act, 2025, the corresponding provisions have been reorganized into the early salary chapter (around the section 30 series) while keeping the substance largely the same. 

What counts as income from salary? 

Income from salary includes several components, not just your monthly basic pay. Typical components are:

• Basic salary
• Dearness allowance
• House Rent Allowance (HRA)
• Leave travel allowance
• Bonuses and incentives
• Commissions from the employer
• Gratuity
• Leave encashment
• Pension from a former employer
• Perquisites such as a company car or accommodation

Even an advance salary or salary received in arrears falls under income from salary.

Example:

Suppose you work in Bengaluru and your annual salary package looks like this:

Your gross income from salary would be ₹ 15,00,000.

However, the Income Tax Act allows certain deductions before calculating taxable salary.

Standard deduction

Under the old 1961 Act , the standard deduction available for salaried individuals is ₹ 50,000. It continues in the new Act but has simply moved from section 16(ia) to section 19 in the Income‑tax Act, 2025. 

So taxable salary becomes:

₹ 15,00,000 – ₹ 50,000 = ₹ 14,50,000

Example:

Assume you pay a rent of ₹ 25,000 per month in a metro city.

Your HRA exemption calculation considers:

• Actual HRA received
• Rent paid minus 10% of salary
• 50% of salary (metro rule)

The lowest of these values becomes exempt under Section 10(13A). As per new income tax act 2025, it falls under section 11‑type income‑not‑included provisions in the new Act, with broadly the same rules for metro vs non‑metro cities (subject to the new HRA‑city list from April 2026). 

This means a portion of your income from salary may become tax-exempt, depending on the rent paid.

TDS on salary

Employers deduct tax directly from your salary under Section 192 of the Income Tax Act.

At the end of the financial year, you receive Form 16, which shows:

• Salary paid
• Tax deducted
• Deductions claimed

When filing your return, you report these figures under the income from the salary head.

2. Income From House Property

If you own real estate that generates rent, that income falls under income from house property under the Income Tax Act.

Even when a property is not rented, certain tax rules may still apply.

Types of property for tax purposes

The Income Tax Act broadly recognises three situations:

Self-occupied property

This is the house you live in. Normally, there is no taxable income here.

Let-out property

If you rent out a house or apartment, the rental income is taxed under income from house property.

Deemed let-out property 

If you own more than two houses, additional properties may be treated as deemed rented.

How income from house property is calculated

The calculation uses the concept of Annual Value.

Step-by-step formula:

Net Annual Value (NAV) = Gross Annual Value – Municipal taxes paid

From NAV, you can claim deductions.

Standard deduction

A flat 30% deduction is allowed for maintenance and repairs.

Example:

Rental income per year = ₹ 6,00,000
Municipal tax paid = ₹ 30,000

NAV = ₹ 5,70,000

Standard deduction = 30% of ₹ 5,70,000 = ₹ 1,71,000

Taxable income from house property becomes:

₹ 5,70,000 – ₹ 1,71,000 = ₹ 3,99,000

Home loan interest deduction

Under Section 24(b) of the Income Tax Act, interest on home loans can be deducted from income from house property.

Limits include:

• Up to ₹ 2,00,000 for self-occupied property

Under the Income‑tax Act, 2025 this deduction has been regrouped into section 22. But the overall limits (like ₹ 2,00,000 cap for interest on home loan for a self‑occupied home under the old regime) remain the same. 

Example:

Suppose you purchased an apartment in Pune with a home loan.

Annual figures:

Rental income = ₹ 3,60,000
Municipal taxes = ₹ 20,000
Interest on loan = ₹ 2,40,000

Net Annual Value = ₹ 3,40,000
Standard deduction = ₹ 1,02,000

Remaining = ₹ 2,38,000

After deducting interest:

₹ 2,38,000 – ₹ 2,40,000 = ₹ 2,000 loss

The Income Tax Act allows you to set off such losses against other income up to ₹ 2,00,000.

3. Income From Business or Profession

If you run a business, work as a consultant or earn money independently without an employer-employee relationship, your earnings fall under profits and gains from business or profession. This category covers a wide range of activities.

Typical examples include:

• Freelancers
• Consultants
• Doctors and lawyers
• Chartered accountants
• Retail traders
• Manufacturing businesses

How business income is calculated

The calculation is straightforward:

Business Profit = Revenue – Allowable Expenses

The Income Tax Act allows the deduction of legitimate business expenses.

These may include:

• Rent for office premises
• Employee salaries
• Electricity and internet bills
• Advertising expenses
• Travel costs
• Depreciation on equipment

Example scenario

Suppose you are a freelance digital marketing consultant.

Annual figures:

Professional fees received = ₹ 18,00,000

Expenses:

Office rent = ₹ 2,40,000
Software subscriptions = ₹ 80,000
Laptop depreciation = ₹ 40,000
Internet and utilities = ₹ 60,000
Marketing expenses = ₹ 1,20,000

Total expenses = ₹ 5,40,000

Taxable income from business or profession becomes:

₹ 18,00,000 – ₹ 5,40,000 = ₹ 12,60,000

Presumptive taxation

Small businesses can use presumptive taxation schemes under Sections 44AD and 44ADA of the old Income Tax Act. These schemes simplify tax calculations.

For example:

• Professionals can declare 50% of receipts as income under Section 44ADA if receipts are within limits.
• Small businesses can declare 6%–8% of turnover as profit under Section 44AD.

This reduces bookkeeping requirements significantly.

Presumptive schemes continue under the new income tax Act, but the section numbers have changed. What used to be sections 44AD / 44ADA are now grouped into the small‑business presumptive chapter in the 130‑series (with the same broad thresholds and 6%/8% / 50% presumptive percentages). 

4. Income From Capital Gains

Whenever you sell an asset and make a profit, that profit becomes income from capital gains.

Assets covered include:

• Real estate
• Shares and securities
• Mutual funds
• Gold
• Bonds

Short-term vs long-term capital gains

The Income Tax Act classifies gains based on holding period.

For listed shares and equity mutual funds:

• Less than 12 months → Short-term
• More than 12 months → Long-term

Holding period rules under the current capital‑gains regime

• Listed equity shares and equity‑oriented mutual funds:
  • Short‑term: held up to 12 months
  • Long‑term: held more than 12 months
• Unlisted shares (including many foreign shares):
  • Short‑term: held up to 24 months
  • Long‑term: held more than 24 months
• Immovable property (land and building, including residential/commercial property):
  • Short‑term: held up to 24 months
  • Long‑term: held more than 24 months
• Most other non‑financial assets such as gold, jewelry, or artwork:
  • Short‑term: held up to 24 months
  • Long‑term: held more than 24 months

Tax rates

For equity investments:

Short-term capital gains: 20%

Long-term capital gains: 12.5% above ₹ 1.25 lakh

For property or other assets:

Long-term gains are typically taxed at 20% with indexation.

Example:

Suppose you bought shares worth ₹ 2,00,000.

After 18 months, you sell them for ₹ 3,20,000.

Capital gain:

₹ 3,20,000 – ₹ 2,00,000 = ₹ 1,20,000

Since this is a long-term equity gain and below the exemption threshold of ₹ 1.25 lakh, your income from capital gains may not attract tax.

These rates reflect the post‑July‑2024 capital‑gains overhaul, which the Income‑tax Act, 2025 carries forward: for listed equity and equity‑oriented mutual funds, short‑term gains are taxed at 20%, and long‑term gains at 12.5% on the portion above ₹ 1.25 lakh, ignoring surcharge and cess.

Capital gains exemptions

The Income Tax Act offers exemptions under certain sections.

Important ones include:

Section 54

Exemption if you reinvest gains from selling a house into another residential property.

Section 54EC

Exemption on the gains if you invest the amount in notified bonds, such as those issued by NHAI or REC.

These provisions allow taxpayers to manage income from capital gains more efficiently.

In new income tax act 2025

Capital‑gains exemptions have been renumbered but retained. 

• Exemption on reinvestment in a new residential house, which earlier fell under section 54, is now provided in section 82 of the Income‑tax Act, 2025 (with capital‑gains computation moved from old section 48 to new section 72) 
• The bond‑based exemption that sat in section 54EC has moved alongside it. The underlying ideas reinvest within a specified time, lock in notified bonds, and investment caps remain similar unless a later Finance Act tweaks them.

5. Income From Other Sources

Not every income fits neatly into the first four heads.

That is where income from other sources comes in. It acts as a residual category under the Income Tax Act.

Typical incomes taxed under this head include:

• Interest from savings accounts
• Fixed deposit interest
• Dividend income
• Lottery winnings
• Gifts from non-relatives
• Family pension

Interest income

Interest earned from savings accounts and fixed deposits is taxed according to your slab rate.

Example:

Savings account interest = ₹ 18,000

You can claim a deduction of ₹ 10,000 under Section 80TTA.

Taxable interest becomes ₹ 8,000.

Under the old Act, the ₹ 10,000 savings‑interest deduction was in section 80TTA, and the senior‑citizen ₹ 50,000 limit in section 80TTB. 

Under the Income‑tax Act, 2025, the old interest‑income deductions under Sections 80TTA and 80TTB have been consolidated into Section 153. It allows up to ₹10,000 deduction on savings‑account interest for non‑senior individuals and HUFs, and up to ₹50,000 for senior citizens on interest from deposits (including FDs and RDs), broadly mirroring the earlier 80TTA/80TTB benefits for taxpayers in the old regime. 

Lottery winnings

Winnings from lotteries or betting are taxed differently. They are taxed at 30% under Section 115BBJ, plus cess and surcharge. No deductions are allowed.

In the new income tax act, Special flat‑rate taxation for windfall incomes (lottery, game shows, etc.) continues under a renumbered provision equivalent to section 115BBJ, still at 30% plus surcharge and cess with no deductions. 

Gifts

If you receive gifts worth more than ₹ 50,000 in a year from people who are not your relatives, the amount is taxed under income from other sources.

However, gifts from relatives such as spouse, parents, or siblings are exempt.

How the 5 Heads of Income Are Used in Income Tax Filing

When you file an income tax return, you do not simply enter your total income.

Instead, the Income Tax Act requires you to classify earnings under the appropriate head.

For example, your ITR may look like this:

Total income = ₹ 16,90,000

After adding all heads together, deductions under Chapter VI-A are applied.

These may include:

• Section 80C investments
• Section 80D health insurance
• Section 80CCD pension contributions

This process ultimately determines your taxable income under the Income Tax Act.

How Deductions Apply Across Income Heads

One important detail many taxpayers overlook is that deductions do not apply uniformly across all heads. The Income Tax Act assigns specific deductions to specific income categories.

Salary deductions

These include:

• Standard deduction ₹ 50,000
• Professional tax

House property deductions

These include:

• Interest on home loan
• Standard deduction of 30%

Business deductions

Here, the law allows deduction of actual business expenses, such as:

• Office rent
• Salaries
• Depreciation

Capital gains exemptions

These involve reinvestment provisions such as:

• Section 54
• Section 54F
• Section 54EC

Other source deductions

Interest income deductions include:

• Section 80TTA (₹ 10,000)
• Section 80TTB (₹ 50,000 for senior citizens)

Understanding where deductions apply helps reduce your tax liability legally under the Income Tax Act.

Under the Income‑tax Act, 2025, most Chapter VI‑A deductions are preserved but renumbered. For example, section 80C (investments) now appears as section 123, 80CCD (NPS) as section 124, 80D (medical insurance) as section 126, and the small‑taxpayer rebate that was under section 87A now sits in section 156. If you are using the old tax regime, your planning logic around these sections stays broadly the same; only the section numbers quoted in forms and advice change. 

Note: Most of the deduction sections are applicable in the Old Tax Regime. Carefully evaluate which regime suits your situation better or consult a tax expert.

Conclusion

The five heads of income under the Income Tax Act form the backbone of India’s income tax system. Every rupee you earn must fall under one of these categories. For most taxpayers, the primary heads include income from salary, income from house property, income from capital gains, and sometimes income from other sources.

The classification may look procedural, but it plays an important role in how tax is calculated. Each head has its own calculation rules, exemptions, and deductions. When you file your return, the first step is always organising your earnings according to these heads.

Once you understand this structure, tax filing becomes more logical. Instead of looking at income as one large number, you see how each type of earning is treated under the Income Tax Act. And that clarity often makes tax planning far easier.
