To provide the text, context and practical orientation for the Income-tax Act, 1961, a central fiscal statute governing levy, computation, assessment, collection and administration of income-tax in India.
Overview #
The Income-tax Act, 1961 is the principal legislation governing income-tax in India. It consolidates and amends the law relating to income-tax and super-tax, and provides the statutory framework for charging tax on income, determining taxable income, filing returns, assessment, deduction and collection of tax at source, advance tax, penalties, prosecution, appeals and recovery.
The Act extends to the whole of India and, except as otherwise provided, came into force on 1 April 1962. The PDF available on this page is described as the Income-tax Act, 1961 as amended by the Finance Act, 2026. Because income-tax law changes frequently through annual Finance Acts, notifications, circulars and rules, users should always verify the current position before relying on any provision for filing, advisory, litigation or compliance purposes.
Object of the legislation #
The object of the Income-tax Act, 1961 is to create a complete statutory code for taxing income in India. It identifies the persons who may be taxed, the income that is chargeable, the manner in which income is computed under different heads, the deductions and exemptions available, and the machinery by which tax is assessed, collected, recovered and disputed.
The Act also serves an administrative and compliance purpose. It empowers the income-tax authorities to obtain information, conduct assessments, require tax deduction or collection at source, levy interest and penalties, and regulate appeals and rectification mechanisms. For businesses, professionals and institutions, including companies, LLPs, partnerships, hospitals, pharmacies and other healthcare enterprises, the Act is central to financial reporting, tax planning and statutory compliance.
Scope and relevance #
The Act applies across India and covers individuals, Hindu undivided families, firms, LLPs, companies, associations of persons, bodies of individuals, local authorities and other taxable persons. Its practical scope includes taxation of salary, business and professional income, capital gains, income from house property, income from other sources, charitable and institutional receipts, international income, deductions, exemptions, loss set-off, return filing, assessment and appellate remedies.
For legal researchers and practitioners, the Act is relevant not only as a tax statute but also as a compliance framework connected with company law, partnership law, contracts, accounts, audits and business structuring. For the pharmaceutical, healthcare and allied sectors, it has day-to-day relevance for business income, professional receipts, depreciation, TDS on payments, charitable hospital or trust taxation, employee tax compliance, payments to vendors and documentation during scrutiny or assessment proceedings.

How to use this Bare Act #
- Use the PDF as a bare statutory text and first identify the relevant assessment year, because income-tax provisions may differ from year to year.
- Read charging, definition and computation provisions together; a term defined in Section 2 or elsewhere may materially change the tax result.
- For business or professional issues, cross-check the computation provisions with the applicable Income-tax Rules, audit requirements, TDS provisions and current Finance Act amendments.
- For litigation or advisory work, verify whether the provision has been amended, substituted, omitted or made applicable from a particular date.
