Scope of Income

Income under the Income‑Tax Act means any receipt of money or its equivalent that is earned by an individual, Hindu Undivided Family (HUF) or a firm during a financial year. The Act uses a broad definition to capture earnings from salaries, business, property, capital gains and other sources.

The definition is intentionally expansive because tax policy aims to tax the economic benefit received, not just cash in hand. Therefore, even non‑cash benefits such as perquisites, stock options, or the fair market value of a gifted asset are treated as income if they satisfy the statutory conditions.

For the NISM exam, remembering that "income" includes both cash and non‑cash receipts helps you avoid the common mistake of ignoring perquisites or deemed income while answering classification questions.

The Act classifies income into five distinct heads: Salary, House Property, Business or Profession, Capital Gains and Other Sources. Each head has its own set of rules for inclusion, deductions and exemptions, which the exam frequently tests through scenario‑based questions.

Salary includes basic wages, allowances, perquisites and bonuses. House Property covers rental income from a residential or commercial building, after allowing for standard deduction and interest on borrowed capital. Business or Profession captures profits from trade, commerce, manufacturing or professional services.

Capital Gains arise when a capital asset is transferred for a consideration exceeding its cost of acquisition. Other Sources is a residual head that captures income not covered elsewhere, such as interest, dividends, winnings and gifts.

Not every receipt is taxable. The Act distinguishes between "income" (taxable) and "exempt income" (non‑taxable). An amount is taxable if it is earned, accrued or received during the financial year and is not specifically exempted by law.

Exempt income includes agricultural income, certain allowances for government employees, and specific capital gains exemptions (e.g., Section 54 for residential house). However, the exemption is conditional – the asset must be sold after a specified holding period and the proceeds must be reinvested as prescribed.

For NISM candidates, the exam often asks you to identify whether a given receipt falls under taxable or exempt categories. Remember the rule: if the receipt is not mentioned in any exemption clause, it is automatically taxable under the appropriate head.

Gross Total Income (GTI) is the sum of income from all five heads after applying head‑specific deductions but before Chapter VI‑A deductions. The computation follows a step‑wise approach: first calculate income under each head, then aggregate.

For each head, the law prescribes standard deductions (e.g., 30% for house property) and specific allowances (e.g., depreciation for business). These are subtracted from the gross receipts of that head to arrive at the net income for the head.

Once GTI is determined, you apply deductions under Chapter VI‑A (such as Section 80C, 80D, etc.) to arrive at the final taxable income. The exam frequently tests the order of these steps, so memorising the sequence is essential.

Section 10 of the Income‑Tax Act lists several exempt incomes. Key examples include agricultural income (if less than ₹5,00,000), certain allowances for government employees, and interest on tax‑free bonds. Each exemption has a specific condition that must be satisfied.

Capital gains exemptions are provided under Sections 54, 54F, 54EC, etc. For instance, long‑term capital gains from the sale of a residential house can be exempted up to the amount reinvested in another residential property within the prescribed time‑frame.

Remember that exemptions reduce Gross Total Income, not taxable income directly. The exam may present a scenario where a student incorrectly deducts an exemption after applying Chapter VI‑A deductions – that is a typical error to avoid.
