Income-tax I: Concepts, Residential Status, Exemptions, Heads of Income, Deductions and Clubbing

Unit 10 is the only unit of the Commerce paper in which the answer can change from one year to the next, because the Finance Act rewrites the numbers every February. The syllabus, however, asks concepts: what an assessee and a previous year are, how residence is decided and what it does to the scope of income, which incomes are exempt and how agricultural income is treated, the five heads and their computation, the Chapter VI-A deductions, how an individual is assessed and when another person's income is taxed as yours. This chapter gives each of those as the rule plus the current figure, labelled with the financial year it belongs to, and opens by placing the Income-tax Act, 2025 that took over from the 1961 Act this April.

1. Basic concepts, and the change of statute

ℹ️ The Income-tax Act, 2025 is in force from 1 April 2026
Parliament passed the Income-tax Act, 2025 in August 2025 to replace the Income-tax Act, 1961, and it applies from 1 April 2026 — the tax year 2026-27 is the first under it. It was written as a simplification, not a change of policy: the heads of income, the residence tests, the exemptions, the deductions and the clubbing rules carry over, while the twin concepts of 'previous year' and 'assessment year' are replaced by a single 'tax year', provisos and explanations are recast as tables and formulae, and every section is renumbered. Textbooks, the NTA vocabulary and the questions asked so far use the 1961 Act's section numbers, and so does this chapter; where a section number appears below, it is the 1961 section, and the 2025 Act's provision on the same point carries a different number. The rates quoted are those for the financial year 2025-26 set by the Finance Act, 2025.
The definitions the paper asks
TermMeaningPoint tested
Assessment year, s. 2(9)The period of twelve months beginning on 1 April in which income of the previous year is assessedIncome earned in financial year 2025-26 is assessed in assessment year 2026-27; the 2025 Act merges the two into 'tax year'
Previous year, s. 3The financial year immediately preceding the assessment year, in which the income is earned; for a new business or source, from the date it beginsUniform for all assessees since 1989; the exceptions where income is taxed in the year earned are shipping business of non-residents, persons leaving India, AOPs formed for a short time, and persons likely to transfer property to avoid tax
Person, s. 2(31)Seven categories: individual, Hindu undivided family, company, firm, association of persons or body of individuals, local authority, and every artificial juridical personA deity, a university, a bar council are artificial juridical persons; a firm includes an LLP
Assessee, s. 2(7)A person by whom any tax or other sum is payable, including a deemed assessee (a representative such as a legal heir or agent of a non-resident) and an assessee in default (one who fails to deduct or pay tax)An assessee need not have income — a person against whom proceedings are taken is one
Income, s. 2(24)An inclusive definition: profits and gains, dividend, perquisites, capital gains, winnings from lotteries and games, gifts above 50,000 rupees from non-relatives, and moreIncludes illegal income and receipts in kind; excludes capital receipts unless specifically taxed and pure gifts from relatives
Gross total income and total income, ss. 80B(5), 2(45)Gross total income is the aggregate of the five heads after set-off of losses; total income is what remains after Chapter VI-A deductionsTax is charged on total income, rounded to the nearest ten rupees (s. 288A); tax is rounded likewise (s. 288B)

Income-tax is a direct tax on the total income of the previous year of every person, charged under section 4 at the rates fixed each year by the Finance Act, which Parliament passes with the Union Budget under Article 265 — no tax shall be levied or collected except by authority of law. The Act is administered by the Central Board of Direct Taxes under the Department of Revenue. Capital receipts are not income unless the Act makes them so — a compensation for loss of a capital asset is capital, compensation for loss of profits is revenue. Income is taxed on the basis of receipt or accrual depending on the head and the method of accounting regularly followed, and the burden of proving that a receipt is not income lies on the assessee once the department shows the receipt.

2. Residential status and tax incidence; exempt incomes and agricultural income

Residence is decided afresh for every previous year on physical presence, not on citizenship or domicile. An individual is resident in India under section 6(1) if in the previous year the individual was in India for 182 days or more, or was in India for 60 days or more in the previous year and 365 days or more in the four preceding years. The 60-day limb is relaxed to 182 days for an Indian citizen leaving India for employment or as a crew member of an Indian ship, and for an Indian citizen or person of Indian origin visiting India — except that a visiting citizen or person of Indian origin whose Indian income exceeds 15 lakh rupees becomes resident at 120 days, and is then treated as resident but not ordinarily resident. Section 6(1A), added in 2020, deems an Indian citizen with Indian income above 15 lakh rupees who is not liable to tax in any other country to be resident — again as not ordinarily resident. A resident is 'ordinarily resident' unless the individual was non-resident in nine of the ten preceding years or was in India for 729 days or less in the seven preceding years; failing either test makes the individual resident but not ordinarily resident. A Hindu undivided family is resident if its control and management is even partly in India, and ordinarily resident by reference to its karta; a company is resident if it is an Indian company or its place of effective management is in India.

Any other income accruing and received outside IndiaTaxableNot taxableNot taxable
Past untaxed foreign income remitted to IndiaNot taxable — remittance is not receiptNot taxableNot taxable

Section 10 lists incomes that do not form part of total income at all. The ones the paper asks are agricultural income (10(1)); a member's share of HUF income (10(2)) and a partner's share of firm profit (10(2A)), since the family and the firm are taxed themselves; leave travel concession (10(5)); death-cum-retirement gratuity, exempt fully for government employees and up to 20 lakh rupees for others under the Payment of Gratuity Act (10(10)); commuted pension (10(10A)); leave encashment on retirement up to 25 lakh rupees for non-government employees (10(10AA)); retrenchment compensation (10(10B)); voluntary retirement compensation up to 5 lakh rupees (10(10C)); payments from a statutory or recognised provident fund and the Public Provident Fund (10(11), 10(12)); house rent allowance to the extent of the least of actual HRA, rent paid less 10% of salary, and 50% of salary in the four metros or 40% elsewhere (10(13A)); scholarships (10(16)); awards instituted by government (10(17A)); income of local authorities, certain funds and institutions; and dividend from a domestic company, which was exempt under 10(34) until 31 March 2020 and has been taxable in the shareholder's hands since the dividend distribution tax was abolished. Long-term capital gains on listed equity are exempt up to 1.25 lakh rupees a year under section 112A, a partial exemption rather than a section 10 item.

🎯 Agricultural income: exempt, yet integrated
Agriculture is a State subject, so section 10(1) exempts agricultural income as section 2(1A) defines it: rent or revenue from land in India used for agricultural purposes, income from agricultural operations on such land including processing ordinarily employed to make the produce marketable, and income from a farm building on or near the land. Basic operations on the land — tilling, sowing, watering — are essential; so income from dairying, poultry, or timber cut from spontaneous growth is not agricultural, and for tea the Rules deem 60% of composite income agricultural, coffee 75% or 60%, rubber 65%. Then comes partial integration: where an individual, HUF, AOP or artificial juridical person has net agricultural income above 5,000 rupees and non-agricultural income above the basic exemption limit, tax is computed on the aggregate, then on agricultural income plus the exemption limit, and the difference is the tax — so agricultural income pushes the other income into higher slabs without itself being taxed.

3. Computation of taxable income under the five heads

The five heads of income, section 14
Head and sectionsWhat is chargedHow it is computedCurrent figures, FY 2025-26
Salaries, ss. 15–17Salary due or paid by an employer, including wages, pension, gratuity, fees, commission, perquisites, profits in lieu of salary, advance salary and leave encashment; needs an employer-employee relationshipGross salary less section 10 exemptions (HRA, gratuity and the rest) gives salary; less section 16 deductions — standard deduction, entertainment allowance for government employees, professional tax — gives income from salary; perquisites valued under Rule 3Standard deduction 50,000 rupees in the old regime, 75,000 in the new regime
Income from house property, ss. 22–27The annual value of buildings and land appurtenant of which the assessee is owner, not used for own business; a deemed owner includes a transferor to spouse or minor child without considerationGross annual value (higher of expected rent and actual rent, expected rent capped at standard rent) less municipal taxes paid gives net annual value; less 30% standard deduction (s. 24(a)) and interest on borrowed capital (s. 24(b)); a self-occupied house has nil annual valueUp to two houses may be treated as self-occupied; interest deduction on them capped at 2 lakh rupees (30,000 if the loan is not for acquisition or construction within five years); pre-construction interest allowed in five equal instalments; loss set-off against other heads capped at 2 lakh rupees
Profits and gains of business or profession, ss. 28–44DBProfits of any business or profession carried on at any time in the previous year, including speculative business, export incentives, compensation for termination of agency, and keyman insuranceNet profit per accounts adjusted for expressly allowed deductions (rent, repairs, insurance, depreciation under s. 32, bad debts, general deduction under s. 37 for revenue expenditure wholly for business) and disallowances (s. 40 for tax not deducted, s. 40A for excessive payments to relatives and cash payments above 10,000 rupees, s. 43B for statutory dues unpaid by the return date)Presumptive taxation: 8% of turnover (6% for digital receipts) for businesses up to 2 crore rupees under s. 44AD, 3 crore where cash receipts are under 5%; 50% of gross receipts for professionals up to 50 lakh under s. 44ADA, 75 lakh with the same cash condition; tax audit under s. 44AB above 1 crore turnover, 10 crore with the 5% cash condition, 50 lakh for professions
Capital gains, ss. 45–55AProfit on transfer of a capital asset in the previous year; a capital asset is property of any kind except stock-in-trade, personal effects other than jewellery, art and the like, and rural agricultural landFull value of consideration less expenses of transfer, cost of acquisition and cost of improvement; long-term if held more than 12 months for listed securities, units of equity funds and zero-coupon bonds, and more than 24 months for every other asset since 23 July 2024; the fair market value on 1 April 2001 may be adopted as cost for assets acquired earlierLong-term gains taxed at 12.5% without indexation (s. 112), and on listed equity at 12.5% above an exemption of 1.25 lakh rupees (s. 112A); short-term gains on listed equity at 20% (s. 111A), other short-term gains at slab rates; resident individuals and HUFs may still choose 20% with indexation on land or buildings acquired before 23 July 2024 if it gives a lower tax; exemptions on reinvestment under ss. 54, 54B, 54EC (bonds, 50 lakh cap) and 54F
Income from other sources, ss. 56–59The residuary head: dividend, interest on securities and deposits, winnings from lotteries, crossword puzzles, races and games, family pension, gifts above 50,000 rupees from non-relatives, income from letting machinery, and any income not falling under the other headsDeductions under s. 57 for expenses to earn the income — collection charges, interest on money borrowed to invest, one-third of family pension up to 15,000 rupees (25,000 in the new regime); no deduction against winningsWinnings from lotteries, games and online games taxed at a flat 30% (ss. 115BB, 115BBJ) with no basic exemption; dividend taxable at slab rates with interest on borrowing deductible up to 20% of the dividend
⚠️ Which loss can be set off against what
Section 70 allows set-off within a head and section 71 across heads, with four blocks. A business loss may not be set off against salary. A speculation loss may be set off only against speculation profit, and a loss from owning and maintaining racehorses only against that activity. A capital loss may be set off only against capital gains — long-term only against long-term, short-term against either. A house-property loss may be set off against other heads only up to 2 lakh rupees, the rest carried forward. Carry-forward runs eight years for business, house-property and capital losses, four years for speculation and racehorse losses, and indefinitely for unabsorbed depreciation; business and capital losses can be carried forward only if the return was filed by the due date, but house-property loss and depreciation need no timely return.

4. Deductions from gross total income, assessment of individuals and clubbing of income

Chapter VI-A deductions the paper asks (old regime, FY 2025-26)
SectionForLimit
80CLife insurance premium, provident fund, PPF, ELSS, NSC, five-year bank deposit, tuition fees for two children, home-loan principal, Sukanya Samriddhi1.5 lakh rupees, shared with 80CCC (pension plans) and 80CCD(1) (NPS) under 80CCE
80CCD(1B), 80CCD(2)Additional own NPS contribution; employer's NPS contribution50,000 extra; employer's contribution up to 10% of salary (14% for government employees, and for all under the new regime) — 80CCD(2) survives in the new regime
80DMedical insurance premium and preventive health check-up; medical expenditure of uninsured senior citizens25,000 for self and family, 50,000 if a senior citizen; the same again for parents; check-up within it up to 5,000
80DD, 80UMaintenance of a dependant with disability; the assessee's own disability75,000; 1.25 lakh for severe disability — flat, regardless of spending
80EInterest on a loan for higher education of self, spouse, children or a student for whom the assessee is guardianNo monetary limit; for eight years from the year repayment begins
80GDonations to approved funds and institutions100% or 50%, with or without a qualifying limit of 10% of adjusted gross total income; no deduction for cash above 2,000 rupees
80GGRent paid by a person who receives no HRA and owns no house at the place of workLeast of 5,000 a month, 25% of total income, and rent less 10% of total income
80TTA, 80TTBInterest on savings accounts; all deposit interest for senior citizens10,000; 50,000 for senior citizens in place of 80TTA
  1. Determine residential status for the previous year, and so the scope of income under section 5.
  2. Compute income under each head separately after the exemptions and deductions of that head, and add income clubbed under sections 60 to 64.
  3. Set off current losses within and across heads (ss. 70–71) and brought-forward losses (ss. 72–74A); the total is gross total income.
  4. Deduct Chapter VI-A — in the old regime; in the new regime only the standard deduction, employer's NPS under 80CCD(2), 80CCH for Agnipath and 80JJAA for new employment survive — to reach total income, rounded to ten rupees.
  5. Apply the rates — the slabs for normal income, special rates for capital gains and winnings, and partial integration for agricultural income — then the rebate under section 87A for a resident individual.
  6. Add surcharge where total income exceeds 50 lakh rupees (10%, 15% above 1 crore, 25% above 2 crore, 37% above 5 crore in the old regime, capped at 25% in the new; 15% on capital gains and dividend), with marginal relief, then health and education cess at 4% on tax plus surcharge.
  7. Less TDS, TCS and advance tax paid; the balance is self-assessment tax under section 140A, payable with interest under sections 234A, 234B and 234C before the return is filed.

Clubbing, sections 60 to 64, taxes in the hands of one person income that legally belongs to another, so that a family cannot lower its total tax by splitting income among members. Section 60 clubs income transferred without transfer of the asset that produces it; section 61 clubs income from a revocable transfer of assets, and section 62 saves transfers irrevocable for the transferee's lifetime or for at least six years. Section 64(1)(ii) clubs remuneration paid to a spouse by a concern in which the individual has a substantial interest — 20% of voting power or profit — unless the spouse has technical or professional qualification and the pay is attributable to it. Section 64(1)(iv) clubs income from assets transferred to a spouse, and 64(1)(vi) to a son's wife, without adequate consideration or in connection with an agreement to live apart; 64(1)(vii) and (viii) cover transfers to any person for the benefit of the spouse or son's wife. Section 64(1A) clubs all income of a minor child with the parent whose total income is greater, except income of a minor with disability and income from the child's own manual work, skill, talent or specialised knowledge; the parent gets an exemption of 1,500 rupees per child under section 10(32). Section 64(2) clubs income from self-acquired property converted into HUF property. Income on the accretions to a transferred asset — interest reinvested, bonus shares — is not clubbed, and the clubbed income keeps its head.

🧠 The four numbers that open Unit 10 questions
182 days — the first residence test. 729 days in seven years, or non-resident in nine of ten — the line between ordinarily and not ordinarily resident. 5,000 rupees of agricultural income and the basic exemption of other income — the threshold for partial integration. 1,500 rupees per child — the exemption against a minor's clubbed income. Each has appeared as a bare numerical question.

Key takeaways

  • The Income-tax Act, 2025 applies from 1 April 2026 with a single 'tax year' in place of previous and assessment year; the concepts, heads, exemptions and clubbing rules carry over and the 1961 section numbers are what textbooks and questions still use.
  • Residence turns on 182 days, or 60 days plus 365 in four years (120 days for visiting citizens with Indian income over 15 lakh); ordinarily resident fails on nine-of-ten non-residence or 729 days in seven years; ROR is taxed on world income, RNOR adds only business controlled from India, NR only Indian income.
  • Agricultural income is exempt under 10(1) but partially integrated above 5,000 rupees when other income exceeds the basic exemption; a partner's share and an HUF member's share are exempt because the firm and family are taxed.
  • Five heads under section 14; house property gets a 30% standard deduction and 2 lakh of interest; long-term is 12 months for listed securities and 24 months for everything else, taxed at 12.5% without indexation; business loss never offsets salary and capital loss only capital gains.
  • 80C caps at 1.5 lakh with 50,000 more for NPS under 80CCD(1B); the new regime is the default with slabs from 4 lakh, a 75,000 standard deduction and a rebate that zeroes tax up to 12 lakh; a minor's income is clubbed with the higher-earning parent less 1,500 per child.

Practice questions (9)

Attempt each one before opening the answer. Every explanation names the tempting wrong option as well as the right one, because that is where marks are lost.

  1. Income earned during the financial year 2025-26 is assessed to income-tax in the assessment year:

    1. 2026-27
    2. 2025-26
    3. 2024-25
    4. 2027-28
    Show answer

    Answer: A — 2026-27

    Income of the previous year is assessed in the assessment year that follows it, beginning 1 April 2026. The Income-tax Act, 2025 replaces the pair with a single 'tax year' from that same date.
  2. An individual who was in India for 100 days in the previous year and for 400 days in the four preceding years, and who is neither leaving for employment nor visiting as a citizen or person of Indian origin, is:

    1. Resident, because the 60-day and 365-day conditions are both met
    2. Non-resident, because the stay is less than 182 days
    3. Resident only if an Indian citizen
    4. Non-resident, because the four-year stay is less than 730 days
    Show answer

    Answer: A — Resident, because the 60-day and 365-day conditions are both met

    Section 6(1) has two alternative tests — 182 days, or 60 days in the year plus 365 days in the four preceding years. 100 and 400 satisfy the second. Citizenship is irrelevant to residence; 729 days in seven years is the ordinarily-resident test, not the residence test.
  3. Income that accrues and is received outside India from a business controlled from India is taxable in the hands of:

    1. A resident and ordinarily resident, and a resident but not ordinarily resident
    2. A resident and ordinarily resident only
    3. All three categories including a non-resident
    4. None, because it is foreign income
    Show answer

    Answer: A — A resident and ordinarily resident, and a resident but not ordinarily resident

    Section 5(1) taxes an RNOR on Indian income plus foreign income from a business controlled from or a profession set up in India; the ROR is taxed on all world income. A non-resident is taxed only on income received or accruing in India, so the control-from-India limb does not reach the non-resident.
  4. Partial integration of agricultural income with non-agricultural income applies to an individual when net agricultural income exceeds 5,000 rupees and:

    1. Non-agricultural income exceeds the basic exemption limit
    2. Agricultural income exceeds 50% of total income
    3. The land is situated in an urban area
    4. The individual is a non-resident
    Show answer

    Answer: A — Non-agricultural income exceeds the basic exemption limit

    Both conditions must hold. Tax is then computed on the aggregate and on agricultural income plus the exemption limit, and the difference is payable, so the exempt income raises the rate on the taxable income without being taxed itself.
  5. Under the head 'Income from house property', the standard deduction from net annual value under section 24(a) is:

    1. 30% of net annual value
    2. 50,000 rupees
    3. Actual repairs incurred
    4. 2 lakh rupees
    Show answer

    Answer: A — 30% of net annual value

    A flat 30% of net annual value is allowed whatever is actually spent on repairs. Two lakh rupees is the interest cap for a self-occupied house under section 24(b), and 50,000 (or 75,000) is the standard deduction from salary.
  6. For a transfer on or after 23 July 2024, a residential house held for how long is a long-term capital asset?

    1. More than 24 months
    2. More than 12 months
    3. More than 36 months
    4. More than 60 months
    Show answer

    Answer: A — More than 24 months

    The Finance (No. 2) Act, 2024 left only two holding periods: 12 months for listed securities, units of equity-oriented funds and zero-coupon bonds, and 24 months for every other capital asset. The 36-month period for other assets was removed.
  7. Which loss can NOT be set off against income under the head 'Salaries'?

    1. Loss from business or profession
    2. Loss from house property up to 2 lakh rupees
    3. Loss from other sources other than racehorses
    4. All of these can be set off against salary
    Show answer

    Answer: A — Loss from business or profession

    Section 71(2A) bars setting off a business loss against salary income. House-property loss may be set off against any head up to 2 lakh rupees, and an ordinary other-sources loss against any head; speculation, racehorse and capital losses are confined to their own kind.
  8. The aggregate deduction under sections 80C, 80CCC and 80CCD(1), by virtue of section 80CCE, cannot exceed:

    1. 1,50,000 rupees
    2. 1,00,000 rupees
    3. 2,00,000 rupees
    4. 50,000 rupees
    Show answer

    Answer: A — 1,50,000 rupees

    The combined ceiling is 1.5 lakh rupees. The additional 50,000 for own NPS contribution under 80CCD(1B) sits outside this ceiling, so the effective total can reach 2 lakh, but the 80CCE cap itself is 1.5 lakh.
  9. Under section 64(1A), the income of a minor child is clubbed with the income of:

    1. The parent whose total income, before clubbing, is greater — except income from the child's own skill, talent or manual work, or of a child with disability
    2. The father in every case
    3. The parent chosen by the child
    4. Neither parent; the minor is assessed separately
    Show answer

    Answer: A — The parent whose total income, before clubbing, is greater — except income from the child's own skill, talent or manual work, or of a child with disability

    The higher-earning parent takes the minor's income, with an exemption of 1,500 rupees per child under section 10(32); where the marriage does not subsist, the parent who maintains the child. Income from the minor's own manual work, skill, talent or specialised knowledge, and any income of a minor with a disability under section 80U, is excluded from clubbing.
