Section 2 explained: this guide covers what it means, who it applies to, the step-by-step process, documents required, fees, due dates and penalties in India — so you can stay compliant with confidence and avoid costly mistakes.
Section 2 is the dictionary of the Act. It opens with the words "In this Act, unless the context otherwise requires", and every defined term then carries its listed meaning wherever it appears. This article covers clauses (1) to (21), from "accountant" to "business trust", as per the Income-tax Act, 2025 (30 of 2025) as amended by the Finance Act, 2026. These terms decide how income is classified on a return, which is why our income tax return filing work begins with them.
Clauses (1) to (21) of section 2 define terms such as agricultural income, amalgamation, assessee, Assessing Officer, block of assets, books of account and business trust. Several are definitions in full; others simply point to another section. Section 2 was amended by section 35 of the Finance Act, 2026. The remaining clauses are explained in our sibling articles, linked below.
How section 2 is organised
Section 2 has 112 numbered clauses in alphabetical order. This article takes the first twenty-one. The rest are split over five more articles: clauses (22) to (35) are in the article on capital asset, charitable purpose, company and demerger, clauses (36) to (48) in the article on dividend, fair market value, firm and foreign company, and the others in the articles on income and interest, on person and resident, and on transfer and virtual digital asset. The meaning of "tax year" is in section 3; see our article on sections 1 and 3.
Clauses that only point elsewhere
Some clauses give no meaning of their own; they send the reader to another provision.

| (2) | Additional Commissioner | A person appointed to be an Additional Commissioner of Income-tax under section 237(1) |

For the annual value, see our post on Section 21 and annual value. The Central Boards of Revenue Act, 1963 is another law; its terms are not explained here and the reader should check it.
Clause (5): agricultural income
This is the longest of the early clauses. Agricultural income means:
- (a) any rent or revenue derived from land situated in India and used for agricultural purposes;
- (b) any income derived from such land by (i) agriculture, (ii) the performance by a cultivator or receiver of rent-in-kind of any process ordinarily employed to render the produce fit to be taken to market, or (iii) the sale by a cultivator or receiver of rent-in-kind of produce on which no process has been performed other than such a process;
- (c) income from a building owned and occupied by the receiver of the rent or revenue of such land, or occupied by the cultivator or receiver of rent-in-kind, where the building is on or in the immediate vicinity of the land and is required as a dwelling house, store-house or other out-building by reason of his connection with the land; and
- (d) income derived from saplings or seedlings grown in a nursery.
For a building under (c), two conditions apply together. The land must be assessed to land revenue in India or be subject to a local rate assessed and collected by Government officers; where it is not, it must not be in an area specified in clause (22)(iii)(A) or (B). The building must also be required as a dwelling house or store-house or other out-building.
The definition does not include: (i) income from a building or land referred to in (c) that arises from using it for any purpose other than agriculture, including letting it for residence or for a business or profession; or (ii) income from the transfer of land referred to in clause (22)(iii)(A) or (B).
Clause (6): amalgamation
For companies, amalgamation means the merger of one or more companies with another company, or of two or more companies to form one. The merging companies are the amalgamating company or companies; the surviving or newly formed company is the amalgamated company. Three conditions must all hold:
- All the property of the amalgamating company or companies immediately before the amalgamation becomes the property of the amalgamated company.
- All their liabilities likewise become the liabilities of the amalgamated company.
- The shareholders holding not less than three-fourths in value of the shares in the amalgamating company or companies become shareholders of the amalgamated company. Shares already held immediately before by the amalgamated company, its nominee or its subsidiary are left out of this count.
The result must not come from one company acquiring the property of another by purchase, or from distributing that property to the other company after the first is wound up.
Clauses (11) to (13): assessee, Assessing Officer, assessment
Assessee (clause 11). A person by whom any tax or any other sum of money is payable under the Act. It also includes every person in respect of whom a proceeding has been taken for assessing his income, his loss or a refund due to him, or the income, loss or refund of another person whom he is assessable for; every person deemed to be an assessee; and every person deemed to be an assessee in default.
Assessing Officer (clause 12). (a) The Assistant Commissioner, Deputy Commissioner, Assistant Director, Deputy Director or Income-tax Officer who is vested with jurisdiction by directions or orders under section 241(1), (2) or (3) or any other provision; and (b) the Additional Commissioner, Additional Director, Joint Commissioner or Joint Director directed under section 241(5)(b) to exercise the powers and functions of an Assessing Officer.
Assessment (clause 13). Includes reassessment and recomputation.
Clauses (16) to (17): average rate and block of assets
- Average rate of income-tax (16): the income-tax calculated on the total income divided by that total income.
- Block of assets (17): a group of assets within a class comprising tangible assets (buildings, machinery, plant or furniture) or intangible assets (know-how, patents, copyrights, trade-marks, licences, franchises or other business or commercial rights of a similar nature, not being goodwill of a business or profession), in respect of which the same percentage of depreciation is prescribed. The depreciation rules that use the term sit in section 33.
Clauses (19) to (21): books, business, business trust
- Books or books of account (19) include ledgers, day-books, cash books, account-books and other books, kept in written form, in electronic or digital form, on cloud based storage or on an electromagnetic data storage device, or as print-outs of data stored in such form.
- Business (20) includes any trade, commerce or manufacture, or any adventure or concern in the nature of trade, commerce or manufacture.
- Business trust (21) means a trust registered as an Infrastructure Investment Trust or as a Real Estate Investment Trust under the respective Securities and Exchange Board of India Regulations, 2014 made under the Securities and Exchange Board of India Act, 1992. These are other laws; check them for their own terms.
Example: is a farmhouse income agricultural?
Kavita owns land in a village and lives in a house on it that she needs as a dwelling because she cultivates the land. Her income from the crop is within clause (5)(b)(i). The house is within clause (5)(c) only if the land is assessed to land revenue or local rate, or is outside the areas in clause (22)(iii)(A) or (B), and the house is required for her work on the land. If she lets the house to a tenant for residence, clause (5), as excluded under (i), does not treat that rent as agricultural income. The Act's text does not attach a rupee figure to these tests.
