1.1 Constitutional Basis & Overview of Income-tax Law
Article 246 • Entry 82 List IThe authority to levy and collect taxes in India is derived directly from the Constitution of India. Under Article 246 read with the Seventh Schedule, legislative competence is distributed among three lists:
- List I (Union List): Parliament has exclusive power to enact laws on matters enumerated in this list. Entry 82 of List I empowers Parliament to levy "Taxes on income other than agricultural income".
- List II (State List): State Legislatures have exclusive power over matters in this list. Entry 46 of List II grants States power to levy "Taxes on agricultural income".
- List III (Concurrent List): Both Parliament and State Legislatures hold concurrent power; however, no tax entry exists in the Concurrent List (except stamp duties).
The Five Components of Income-tax Law in India
Income-tax law in India does not consist solely of the primary statutory enactment. It functions as an integrated ecosystem of five legal instruments:
| Component | Statutory Source | Legal Force & Practical Scope |
|---|---|---|
| 1. Income-tax Act, 2025 | Primary Central Legislation | Enacted to consolidate and modernize tax administration. Extends to the whole of India. Comprises 23 Chapters, 536 Sections, and 16 Schedules. Came into force on 1st April, 2026. Sets out charging provisions, taxable heads, computation rules, and enforcement mechanisms. |
| 2. Annual Finance Act | Passed annually by Parliament |
Gives statutory effect to financial proposals of the Central Government. The First Schedule contains 4 vital parts:
• Part I: Rates of tax applicable for the current tax year. • Part II: Rates for deduction of tax at source (TDS) from income other than salaries. • Part III: Rates for computing advance tax and TDS from salary income. • Part IV: Rules for computation of net agricultural income for partial integration. |
| 3. Income-tax Rules, 2026 | CBDT powers under Section 534 | Subordinate legislation framed by the Central Board of Direct Taxes (CBDT) for carrying out the purposes of the Act. As per Section 2(80), "prescribed" means prescribed by rules. Rules cannot override or conflict with the parent Act; where conflict arises, the Act prevails. |
| 4. Circulars & Clarifications | Issued by CBDT under Section 239 | Binding on all income-tax authorities and officers subordinate to CBDT. Crucial Rule: Circulars are NOT binding on the assessee, Appellate Authorities (CIT(A)), Income Tax Appellate Tribunal (ITAT), High Courts, or the Supreme Court. However, assessees are entitled to claim the benefit of benevolent/favourable circulars. |
| 5. Judicial Precedents | Supreme Court & High Courts | Decisions of the Supreme Court constitute the law of the land under Article 141 of the Constitution and bind all courts and tribunals in India. Decisions of a High Court bind all subordinate authorities, tribunals, and assessees within its territorial jurisdiction. |
Sec 536 Repeal and Saving Provisions: Transition from 1961 Act
Transitional ContinuitySection 536 repeals the Income-tax Act, 1961 with effect from 1st April, 2026. However, to prevent administrative chaos and legal vacuum, extensive saving provisions are enacted:
- Continuity of Past Proceedings: All pending assessments, reassessments, appeals, revisions, penalty proceedings, and recovery actions relating to tax years commencing prior to 1st April, 2026 continue under the repealed 1961 Act.
- Preservation of Rights & Liabilities: Rights, obligations, privileges, and liabilities incurred under the 1961 Act remain intact.
- Validity of Past Options & Elections: Options, declarations, agreements, or approvals exercised under the 1961 Act remain valid under corresponding provisions of the 2025 Act.
- Brought Forward Losses & Deductions: Brought forward unabsorbed depreciation, business losses, MAT/AMT credit, and pending amortizations under the repealed Act are carried forward into the Income-tax Act, 2025 as if sustained under corresponding provisions.
Jurisprudence Rules of Statutory Interpretation & Judicial Aids
Tax JurisprudenceTaxation statutes demand rigorous principles of interpretation. Courts employ established cannons of statutory construction to ascertain the true legislative intent:
Underlying maxim: "Judges do not legislate; they only interpret law." If the words of a statute are plain, clear, and unambiguous, courts must give them their natural grammatical meaning. Nothing can be added, subtracted, or implied.
Originated in Heydon’s case (1584). Examines: (1) What was the common law before? (2) What was the mischief/defect unprovided for? (3) What remedy Parliament resolved? (4) The true reason of the remedy. Courts adopt the construction that suppresses the mischief and advances the remedy.
A departure from literal interpretation allowed only when a strictly literal reading produces absurdity, injustice, or repugnance that the legislature could never have intended. The court modifies the grammatical meaning to avert absurdity.
A statute must be read as a whole. Where two provisions appear in conflict, courts must interpret them so as to give effect to both and avoid rendering any provision redundant or inconsistent.
In fiscal statutes, if a provision is capable of two reasonable constructions, the interpretation that favours the taxpayer/subject must be adopted. Exemption and deduction provisions intended to promote economic activity are construed liberally.
• Ejusdem Generis: General words following specific words take color from the specific genus.
• Noscitur a Sociis: Meaning of an unclear word is known by its company.
• Stare Decisis: Longstanding judicial precedents should not be unsettled lightly.
ICAI Master Summary: Construction by Provision Type
| Type of Provision | Governing Canon of Construction | Judicial Practical Application |
|---|---|---|
| Charging Provisions | Strict Construction | Tax cannot be levied on equity, assumption, or intendment. Clear words must bring the subject within the net. |
| Machinery Provisions | Workable / Practical Construction | Provisions for computation, assessment, and recovery are construed to make the machinery operable and not frustrate the levy. |
| Penal Provisions | Strict Construction | Any ambiguity must be resolved in favor of the assessee. Mens rea / statutory fault must be strictly proven. |
| Deeming Provisions | Full Effect to Legal Fiction | A legal fiction must be carried to its logical conclusion, but its scope cannot be extended beyond the statutory purpose. |
| Appeal & Refund Provisions | Liberal Construction | Right of appeal must be explicitly conferred by statute, but procedural conditions are construed liberally to advance justice. |
| Exemptions & Reliefs | Beneficial Construction | Incentives to encourage industry, investment, or charity are interpreted liberally to effectuate the legislative goal. |
Internal Aids vs External Aids to Interpretation
- Non-obstante Clause: Phrases like "Irrespective of anything contained..." give overriding effect over conflicting sections (e.g., Section 35 disallowance overrides Chapter IV-D).
- Headings & Marginal Notes: Can only be used to resolve ambiguity, never to restrict plain text.
- Definition Clauses: Section 2 applies across the Act; Chapter-specific definitions (e.g. Section 402 in Chapter XIX) govern that Chapter only.
- Legislative History: Parliamentary debates and Law Commission reports illuminate the defect intended to be remedied.
- Speech of Finance Minister: Minister's speech introducing the Finance Bill is admissible to ascertain legislative purpose.
- Circulars u/s 239: CBDT circulars provide contemporary executive understanding.
- Dictionaries: Used only when a term is not statutorily defined or judicially settled.
Sec 4 Charge of Income-tax: Four Statutory Pillars
Charging FoundationIncome-tax is charged for any tax year at the rate or rates specified in the Annual Finance Act or the Income-tax Act, 2025 (or both) in respect of the Total Income of the tax year of every Person.
Levied on an annual basis for each Tax Year commencing 1st April.
Computed strictly under the 5 heads after allowable exemptions and deductions.
Levied upon the 7 categories of taxable entities defined under Section 2(77).
Fixed by the Annual Finance Act or special rates embedded in the Act (Sec 193–218, 200–204).
Sec 2 Core Definitions: Assessee, Assessment & Person
Section 2(11), 2(13), 2(77)"Assessee" means a person by whom any tax or any other sum of money is payable under this Act, and includes:
- Ordinary Assessee: Every person by whom any tax, penalty, or interest is payable under the Act.
- Assessment Assessee: Every person in respect of whom any proceeding under this Act has been taken for the assessment of his income, loss, or amount of refund due to him.
- Deemed Assessee: Every person who is deemed to be an assessee under any provision of this Act (e.g., Legal Representative u/s 304 of a deceased assessee; Trustee of a discretionary trust; guardian/manager of a minor or lunatic entitled to receive income by virtue of Section 303 [Representative Assessee]).
- Assessee in Default: Every person who is deemed to be an assessee in default under any provision of this Act (e.g., an employer/payer failing to deduct TDS or pay deducted tax to the Government u/s 397/400).
Assessment [Section 2(13)]: Five Statutory Assessment Types
Assessment is the legal procedure by which the taxable income and tax liability of an assessee are determined. The Act provides five distinct types:
| Assessment Category | Section Reference | Substantive Scope & Trigger Condition |
|---|---|---|
| 1. Self-Assessment | Section 266 | Assessee computes tax, interest, and fee on his own total income and pays it before filing the return. |
| 2. Summary Assessment | Section 270(1) | Centralized electronic processing of return; adjustments for arithmetical errors, incorrect claims, and internal discrepancies. |
| 3. Scrutiny Assessment | Section 270(10) | Comprehensive audit conducted by the Assessing Officer to ensure the assessee has not understated income, computed excessive loss, or underpaid tax. |
| 4. Best Judgment Assessment | Section 271 | Ex-parte assessment by the AO to the best of his judgment when assessee fails to file return, fails to comply with statutory notices, or fails special audit. |
| 5. Reassessment / Income Escaping | Section 279 | Assessment or reassessment initiated when the AO has information suggesting taxable income has escaped assessment. |
Person [Section 2(77)]: The Seven Chargeable Tax Entities
Under Section 2(77), "Person" includes:
(1) Individual: Natural human being.
(2) HUF (Hindu Undivided Family): Assessed as a distinct entity under Hindu personal law.
(3) Company: Indian, domestic, foreign, or public company.
(4) Firm: Includes a partnership firm and a Limited Liability Partnership (LLP).
(5) Association of Persons (AOP) or Body of Individuals (BOI): Whether incorporated or not.
(6) Local Authority: Municipal corporation, district board, port commission, cantonment board.
(7) Every Artificial Juridical Person: Idols, deities, statutory corporations, universities not covered above.
Principle: To form a taxable HUF under the Income-tax Act, it is not mandatory to have more than one male member. An HUF can consist of a single male coparcener and female members (widows, mother, daughters). The property of the joint family does not cease to be HUF property merely because it is represented by a single surviving coparcener.
Sec 2 Company Classifications & Public Interest Criteria
Section 2(42), 2(44), 2(46), 2(53)| Company Category | Section | Statutory Criteria & Legal Characteristics |
|---|---|---|
| Indian Company | Section 2(53) | A company formed and registered under the Companies Act, 2013 (or earlier company laws) whose registered or principal office is located in India. |
| Domestic Company | Section 2(42) | Means an Indian company, OR any other company which has made the prescribed arrangements for the declaration and payment of dividends within India out of its taxable income. |
| Foreign Company | Section 2(46) | A company which is not a domestic company (i.e. a foreign incorporated company that has not made prescribed arrangements for dividend declaration in India). |
| Company in which Public are Substantially Interested | Section 2(44) |
Includes:
1. Government Companies: At least 40% equity held by Govt or RBI. 2. Section 8 Companies: Non-profit entities licensed under Companies Act. 3. Mutual Benefit Societies: Nidhi companies declared by Central Government. 4. Listed Companies: Equity shares listed on a recognized stock exchange in India. 5. Co-operative Society Ownership: At least 50% voting power held by co-operative societies. 6. Public Subsidiaries: Wholly owned subsidiaries of public companies. |
Sec 2(49) Income, Capital vs Revenue Receipts & Landmark Precedents
Inclusive Scope & Judicial TestsThe statutory definition of "Income" is inclusive and not exhaustive. It enumerates 24 specific items including profits and gains, dividends, voluntary contributions to trusts/electoral trusts, value of perquisites u/s 17/18, deemed profits u/s 38/95, capital gains u/s 67, and receipts without consideration u/s 88.
Distinction: Capital Receipts vs. Revenue Receipts
Revenue receipts are prima facie taxable unless specifically exempt by statute.
Capital receipts are prima facie exempt from income-tax unless specifically brought to tax by express statutory words (e.g., Capital gains u/s 67, gifts u/s 88, forfeiture of advance money).
| Test / Criterion | Capital Receipt | Revenue Receipt |
|---|---|---|
| Fixed vs Circulating Capital | Receipt from realization or replacement of fixed capital / profit-earning apparatus. | Receipt from realization or turn-over of circulating capital / stock-in-trade. |
| Tree vs Fruit | Realization of the "tree" (the source itself). | Realization of the "fruit" (the periodic yield from the tree). |
| Sterilization of Apparatus | Compensation for total destruction, sterilization, or cessation of the profit-making apparatus. | Compensation for normal trading loss or loss of future profits. |
| Lump sum vs Periodicity | Single payment for extinguishment of an enduring right. | Periodic, recurring payments arising from continuous commercial activity. |
Facts & Issue: Assessee received liquidated damages from a supplier for delay in delivery and erection of a cement plant.
Ruling: The damages directly related to the acquisition and delay of a capital asset (cement plant). The delay impacted the profit-making apparatus rather than the trading operations. Held to be a capital receipt and not taxable as business income.
Facts & Issue: A scheduled bank purchasing government securities to meet RBI SLR norms paid broken-period interest accrued prior to purchase and claimed it as deduction.
Ruling: Securities held under Available for Sale (AFS) and Held for Trading (HFT) categories constitute stock-in-trade. Hence, broken-period interest is revenue expenditure deductible against business profits.
Doctrine Application of Income vs Diversion by Overriding Title
Landmark Supreme Court Rule
The Core Statutory Principle: To constitute a valid diversion by overriding title, the obligation must attach directly to the source which yields the income, and not merely to the income after it has accrued or arisen.
• Application of Income: Money reaches the assessee or accrues to him first, and is then applied to discharge a personal or legal obligation → Fully Taxable in his hands.
• Diversion by Overriding Title: An overriding enforceable title diverts the money before it reaches or accrues to the assessee → Excluded from Total Income.
• ICAI Tax Planning Note: For legitimate tax planning, the concept of ‘diversion by overriding title’ has substantially greater scope for exploitation than ‘application of income’. In practice, this depends entirely on the meticulous legal drafting of the deed or decree creating the anterior charge upon the income-yielding source.
| Parameter | Diversion by Overriding Title | Application of Income |
|---|---|---|
| Point of Obligation | Attaches to the source itself before income accrues or reaches the assessee. | Attaches to the income after it has accrued to and been received by the assessee. |
| Ownership of Income | Assessee receives it merely as a conduit/agent for the person with the superior title. | Assessee receives it beneficially as his own income and then applies it to discharge a personal liability. |
| Tax Consequence | Excluded from Total Income of the assessee. | Included in Total Income; no deduction allowed unless expressly provided. |
| ICAI Book Example | Firm pays 20% profits to deceased partner's widow pursuant to partnership deed charge. | Advocate donates portion of professional fees to a charitable trust created by himself. |
Review Fundamental Concepts: Salary & House Property Allowances
Basic Review in Chapter 1Chapter 1 of the ICAI study material outlines fundamental deductions and rules under Salary and House Property to establish the baseline for Total Income computations:
- Standard Deduction [Sec 19(1)]:
• Default Regime (Sec 202): Up to ₹75,000 or salary, whichever is lower.
• Optional Normal Regime: Up to ₹50,000 or salary, whichever is lower. - Professional Tax [Sec 19(3)]: Deductible on actual payment basis under the normal regime; disallowed under default regime.
- Retirement Benefits: Statutory gratuity, commuted pension, and leave encashment subject to monetary ceilings.
- Net Annual Value (NAV): Gross Annual Value (higher of Reasonable Expected Rent and Actual Rent) minus Municipal Taxes paid by owner.
- Standard Deduction [Sec 22(1)]: 30% of Net Annual Value (NAV).
- Housing Loan Interest [Sec 22(2)]:
• Self-Occupied: Max ₹2,00,000 under normal regime; NIL under default regime.
• Let-Out: Fully deductible without limit under both regimes (loss set-off against other heads capped at ₹2,00,000). - Arrears of Rent [Sec 23]: Taxable after 30% standard deduction.
Sec 102–107 Unexplained Sources of Income & Section 107 Punitive Tax
78% Punitive Rate • Total Loss BarWhere an assessee fails to explain the source of cash credits, investments, or expenditures, they are brought to tax under Section 107 at a flat punitive rate with strict statutory disallowances.
| Section | Unexplained Source | Statutory Trigger & Statutory Condition |
|---|---|---|
| Section 102 | Unexplained Cash Credits | Sum found credited in books of account of the assessee for which he offers no explanation or explanation is unsatisfactory in AO's opinion. |
| Section 103 | Unexplained Investments | Assessee has made investments not recorded in books of account and offers no explanation regarding source. |
| Section 104 | Unexplained Money, Bullion, Jewellery | Assessee is found to be the owner of money, bullion, jewellery, or valuable articles not recorded in books. |
| Section 105 | Unexplained Expenditure | Assessee incurs expenditure and offers no explanation regarding source. Section 105(2) expressly bars any deduction of such expenditure! |
| Section 106 | Hundi Borrowings / Repayments | Any amount borrowed on Hundi or repaid otherwise than through an account payee cheque drawn on a bank. |
Section 107: Special Rate of Tax on Unexplained Sources under Section 195
Income referred to in Section 102 to 106 is charged @ 30% under Section 195.
Add: Surcharge @ 25% of Tax (7.50%) + HEC @ 4% of (30% + 7.50% = 37.50%) (1.50%) = Effective Tax Rate of 39.00%.
[Legacy 1961 Act Context: Under former Section 115BBE, base tax was 60% + 25% surcharge + 4% cess = 78.00%].
- No Basic Exemption Limit: Tax of 60% applies from the very first rupee of unexplained income.
- No Deductions Allowed: No deduction under Chapter VI-A / Chapter VIII or any business expenditure can reduce this income.
- Strict Loss Set-off Bar: Current year losses or brought forward losses under any head of income cannot be set off against Section 107 income!
Facts: For Tax Year 2026-27, M/s Alpha Traders sustains a business loss of ₹10,00,000. During the scrutiny assessment, the Assessing Officer discovers an unexplained cash credit of ₹20,00,000 under Section 102. Compute the total income and final tax liability.
| Particulars | Amount (₹) | Statutory Working & Reasoning |
|---|---|---|
| Unexplained Cash Credit (Sec 102) | 20,00,000 | Deemed income chargeable u/s 107 |
| Less: Set-off of Business Loss | NIL | Strictly Prohibited: Section 107 bars loss set-off against deemed unexplained income. Business loss of ₹10,00,000 carried forward. |
| Taxable Income u/s 107 | 20,00,000 | Taxed at special punitive rates |
| Computation under Income-tax Act, 2025 [Section 107 read with Section 195]: | ||
| Base Income-tax @ 30% (Sec 195) | 6,00,000 | 30% of ₹20,00,000 as per Section 107 read with Section 195 |
| Add: Surcharge @ 25% of tax | 1,50,000 | 25% of ₹6,00,000 (standard punitive surcharge) |
| Tax + Surcharge | 7,50,000 | Sub-total (37.50% effective) |
| Add: Health & Education Cess @ 4% | 30,000 | 4% of ₹7,50,000 |
| Total Tax Liability u/s 195 (39.0%) | ₹7,80,000 | Effective rate = 39.00% under Income-tax Act, 2025 |
| Comparative Legacy Note: Under Section 115BBE of the 1961 Act, base tax was 60% (₹12,00,000) + 25% surcharge (₹3,00,000) + 4% cess (₹60,000) = ₹15,60,000 (effective rate = 78.00%). | ||

Sec 316–320 Five Statutory Exceptions: Accelerated Assessment
Income Taxed in Year of AccrualGeneral Rule: Income earned in a Tax Year is assessed in the subsequent Assessment Year. The Act carves out five statutory exceptions where income is assessed immediately in the tax year itself to prevent tax avoidance:
| Exception & Section | Statutory Presumption | Accelerated Assessment Mechanism |

| Income-tax @ 35% (Foreign Company) | 2,10,000 | 35% of ₹6,00,000 |
| Add: Surcharge | NIL | Total income ₹6,00,000 does not exceed ₹1 Crore |
| Add: Health & Education Cess @ 4% | 8,40,0 | 4% of ₹2,10,000 |
| Tax Payable Before Port Clearance | ₹2,18,400 | Cleared only upon payment or bank guarantee |
Sec 202 Default Concessional Tax Regime & Statutory Slabs
Default Regime for Individuals, HUF, AOP, BOI & AJPUnder the Income-tax Act, 2025, the concessional regime under Section 202 is the default tax regime for Individuals, HUF, AOP, BOI, and Artificial Juridical Persons. Taxpayers who do not exercise the specific option to opt out under Section 202(4) are assessed under these concessional slabs.
| Total Income Slab (₹) | Rate of Tax | Cumulative Tax at Upper Limit |
|---|---|---|
| Up to ₹4,00,000 | NIL | NIL |

| From ₹20,00,001 to ₹24,00,000 | 25% | ₹3,00,000 |
| Above ₹24,00,000 | 30% | ₹3,00,000 + 30% of amount in excess of ₹24 Lakhs |
Sec 156 Rebate & Marginal Relief for Resident Individuals
Zero Tax Up To ₹12 Lakhs-
Tier 1 — Total Income up to ₹12,00,000:
Resident individuals are entitled to a deduction of 100% of income-tax payable or ₹60,000, whichever is less.
Result: An individual having total income up to ₹12,00,000 pays zero tax! -
Tier 2 — Total Income Exceeding ₹12,00,000 (Marginal Relief Rebate):
Where total income exceeds ₹12,00,000 and the income-tax on such total income exceeds the excess of total income over ₹12,00,000, marginal relief is granted:Rebate u/s 156 = Tax on Total Income [B] − [Total Income − ₹12,00,000] [A]
Net Tax Payable = Total Income − ₹12,00,000 (plus 4% Cess)

| Add: Health & Education Cess @ 4% | 600 | 4% of ₹15,000 |
| Total Tax Liability | ₹15,600 | Fully protected by Section 156 marginal relief |
Sec 202(4) Optional Normal Tax Regime & Senior Citizen Slabs
Regular Slab StructureWhere an assessee opts out of the default regime, tax is levied at the normal rates specified by the Annual Finance Act. Three progressive basic exemption tiers apply based on age:
| Total Income Slab | Individual (< 60 Yrs) | Senior Citizen (60–79 Yrs) | Super Senior (80+ Yrs) |
|---|---|---|---|
| Up to ₹2,50,000 | NIL | NIL | NIL |

Total income must be rounded off to the nearest multiple of ten rupees. If the last digit is 5 or more, it is rounded up to the next higher multiple of ten; if less than 5, it is rounded down.
Example: ₹8,54,325 becomes ₹8,54,330; ₹8,54,324 becomes ₹8,54,320.
The amount of tax, interest, penalty, or refund payable or receivable shall be rounded off to the nearest multiple of ten rupees on the identical principles.
Health & Education Cess: Calculated uniformly @ 4% on (Income-tax + Surcharge − Section 156 Rebate).
TYK ICAI Test Your Knowledge: Practical Exam Problems & Solutions
Six Classic Practical ScenariosQuestion: Mr. Bhargava, a leading advocate on corporate law, agreed to defend a company in the Supreme Court on the condition that he would be provided with ₹5 lakhs for a public charitable trust that he would create. He defended the company, was paid ₹5 lakhs, and created a trust of that sum by executing a trust deed. Decide whether the amount received by Mr. Bhargava is assessable in his hands as professional income.
In this case, the trust was created by Mr. Bhargava himself out of his professional income. The client company did not create the trust, nor did it impose an overriding obligation in the nature of a trust binding on Mr. Bhargava before the income accrued.
Therefore, the income accrued to Mr. Bhargava as professional fees and was subsequently applied by him to fund the trust. This is a clear case of Application of Professional Income and NOT diversion of income by overriding title.
Conclusion: The sum of ₹5,00,000 is fully assessable in his hands under the head "Profits and gains of business or profession".
Question: XYZ Ltd. took over the running business of a sole proprietor by a sale deed. As per the deed, XYZ Ltd. undertook to pay overriding charges of ₹15,000 p.a. to the wife of the sole proprietor in addition to the sale consideration, charged on the net profits of XYZ Ltd. as a condition of purchase. Is the payment diversion of income or application of income?
The overriding charge in favour of the proprietor's wife was an integral condition of the sale deed by which the going concern was acquired. The obligation was attached to the very source of income (the business concern transferred).
The profits to the extent of ₹15,000 p.a. never reached XYZ Ltd. as its beneficial income; they were diverted at source before accrual.
Conclusion: This is a case of Diversion of Income by Overriding Title. The amount is deductible / excludible from the profits of XYZ Ltd.
Question: MKG Agency is a partnership firm of Mohan and his three sons. The deed provided that upon Mohan's death, the business shall continue subject to the condition that the firm pays 20% of profits to their mother, Lakshmi. Mohan died in March 2026. In T.Y. 2026-27, the reconstituted firm paid ₹1,00,000 (20% profits) to Lakshmi and claimed it as deduction. Examine the validity of the claim.
The obligation to pay 20% profits to Lakshmi was created by the partnership deed itself as an overriding condition for the continuation of the firm. The income of ₹1,00,000 was diverted at source before it could become the income of the reconstituted firm.
The firm merely received the amount for and on behalf of Lakshmi, who possesses an overriding title superior to the firm.
Conclusion: The claim of the firm is valid in law. The sum of ₹1,00,000 must be excluded from the firm's total income.
Question: Anand was the Karta of an HUF. He died leaving behind his major son Prem, his widow, his grandmother, and his brother’s wife. Can the HUF retain its status as such, or do the surviving members become co-owners?
The Supreme Court settled that there need not be more than one male member to form or continue an HUF under the Income-tax Act. The expression "HUF" is used in the sense understood under Hindu personal law.
A joint family may consist of a single male member and the widows/female members of deceased coparceners. The joint family property does not cease to belong to the joint family merely because it is represented by a single surviving coparcener.
Conclusion: The entity retains its status as an HUF; the surviving members do NOT become mere co-owners.
Question: Mr. C borrowed on Hundi a sum of ₹25,000 by bearer cheque on 11.09.2026 and repaid the same with interest amounting to ₹30,000 by account payee cheque on 12.10.2026. The AO wants to treat the ₹25,000 borrowed as income during the tax year. Is the AO's action valid?
Under Section 106, where any amount is borrowed on a hundi, or any amount due thereon is repaid, otherwise than through an account-payee cheque drawn on a bank, the amount so borrowed or repaid is deemed to be the income of the person for the tax year in which it was borrowed or repaid.
Here, Mr. C borrowed ₹25,000 by bearer cheque (violating Section 106). Even though the repayment was by account payee cheque, the borrowing itself is hit by Section 106.
Conclusion: The Assessing Officer’s action in treating the ₹25,000 borrowed as deemed income for T.Y. 2026-27 is valid in law.
Question: The AO discovered that a partnership firm paid rent of ₹60,000 for its business premises which was not debited in the books for the year ending 31.3.2027. The firm could not explain the source. The AO proposes an addition of ₹60,000 u/s 105. The firm claims that since the rent was incurred for business purposes, it should be allowed as a business deduction. Examine the firm’s claim.
The unrecorded rent payment constitutes unexplained expenditure under Section 105 because the firm failed to explain the financial source of the payment.
Section 105(2) explicitly states: "Irrespective of any other provision of this Act, such unexplained expenditure, which is deemed to be the income of the assessee, shall NOT be allowed as a deduction under the Act."
Conclusion: The claim of the firm for a business deduction is wholly untenable. The addition of ₹60,000 stands as deemed income, and tax is chargeable @ 78% under Section 107 without any deduction.
