Module IV: Profits and Gains of Business or Profession (PGBP)
Comprehensive, syllabus-aligned study notes covering the statutory framework of Sections 28 to 44DB: scope of charge, speculative transactions, block-of-assets depreciation under Section 32, allowable operational deductions under Sections 30 to 37, statutory disallowances under Sections 40, 40A, and 43B (including the landmark MSME rule Section 43B(h)), presumptive taxation regimes under Sections 44AD, 44ADA, and 44AE, tax audit parameters under Section 44AB, and fully worked practical computations for commercial businesses and medical/legal professions.
1. Meaning, Definition, and Concept of Business and Profession [Unit 20]
Under the Indian Income Tax Act, 1961, "Profits and Gains of Business or Profession" (PGBP) is the third specific head of income governed comprehensively by Sections 28 to 44DB. It constitutes the economic backbone of direct taxation, providing statutory rules for determining true commercial taxable income. The Act deliberately defines business and profession with broad statutory inclusiveness to capture all commercial, industrial, vocational, and professional economic pursuits.
Definition of "Business"
Section 2(13) provides that "Business" includes:
- 1.Any Trade: Buying and selling of goods with an underlying profit motive.
- 2.Any Commerce: Commercial transactions including financial intermediation, transportation, banking, warehousing, and logistics.
- 3.Any Manufacture: Physical, mechanical, or chemical transformation of raw materials or components into a distinct commercial commodity having a new identity and character.
- 4.Any Adventure or Concern in the Nature of Trade, Commerce, or Manufacture: Even an isolated, solitary, or single commercial transaction undertaken with an underlying mercantile intent and commercial character qualifies legally as a business.
Definition of "Profession"
Section 2(36) states that "Profession" includes vocation:
- 1.Profession: An occupation requiring specialized intellectual attainment, formal academic qualification, prolonged theoretical training, and adherence to professional codes of conduct (e.g., Chartered Accountants, Advocates, Medical Practitioners, Engineers, Architects).
- 2.Vocation: Any activity for which a person possesses a special natural fitness, inherent skill, creative aptitude, or talent, whether undertaken professionally or artistically (e.g., painters, authors, musicians, dancers, sculptors, astrologers).
2. Incomes Chargeable under the Head PGBP [Section 28] & Speculative Business [Section 43(5)]
Section 28 serves as the statutory charging section for the head "Profits and Gains of Business or Profession." It designates an exhaustive catalogue of commercial inflows that are statutorily assessed under this head:
Operational Profits
The profits and gains of any business or profession carried on by the assessee at any time during the previous year.
Management Compensation
Any compensation or other payment due to or received by any person managing the affairs of an Indian company or holding an agency upon the termination or modification of the contract.
Trade & Professional Associations
Income derived by a trade, professional, or similar chamber/association from specific operational services performed for its members.
Export Incentives & Subsidies
Profits on sale of import entitlement licenses [Sec 28(iiia)], cash assistance/subsidies received against exports [Sec 28(iiib)], Duty Drawback (DBK) repaid/repayable [Sec 28(iiic)], and profits on transfer of DEPB / DFRC [Sec 28(iiid) & (iiie)].
Perquisites & Business Benefits
The fair market value of any benefit or perquisite, whether convertible into money or not, arising from business or the exercise of a profession (e.g., vendor-sponsored foreign tours, luxury asset gifts).
Remuneration / Interest to Partners
Any salary, bonus, commission, remuneration, or interest on capital received by a partner from his partnership firm (only to the extent allowable as a deduction to the firm under Section 40(b)).
Non-Compete Fees
Any sum received or receivable under an agreement for refraining from carrying out any business/professional activity, or not sharing any patent, copyright, trademark, technical know-how, license, or franchise.
Keyman Insurance & Stock Conversion
Proceeds received under a Keyman Insurance Policy (including bonus) [Sec 28(vi)], and the Fair Market Value (FMV) of inventory/stock-in-trade on the date of its conversion into a capital asset [Sec 28(via)].
Speculative Transactions vs. Ordinary Business [Section 43(5)]
A speculative transaction is defined under Section 43(5) as a transaction for the purchase or sale of any commodity (including stocks and shares) periodically or ultimately settled otherwise than by the actual delivery or physical transfer of the commodity or scrips.
Statutory Separation & Loss Set-Off [Section 73]
Under Explanation 2 to Section 28, where an assessee carries on speculative business, that business is deemed to be distinct and separate from any other non-speculative business.
Under Section 73, losses incurred in a speculative business cannot be set off against non-speculative business income or any other head of income. Speculative losses can only be carried forward for a maximum of 4 assessment years to be set off exclusively against future speculative profits.
Statutory Exceptions (Deemed Non-Speculative)
The following contracts are explicitly excluded by Section 43(5) from being treated as speculative transactions:
- Hedging Contracts: Entered into by raw material manufacturers or merchandise dealers to guard against future price fluctuations.
- Forward Contracts: Entered into by dealers or investors in stocks/shares to guard against loss through price fluctuations.
- Trading in Derivatives: Eligible transactions in equity derivatives, commodity derivatives, or currency derivatives carried out on recognized stock exchanges with STT/CTT paid.
3. Provisions Relating to Depreciation [Section 32] (Unit 25)
Depreciation under the Income Tax Act is a statutory allowance granted for the diminution in value of business assets caused by wear and tear, obsolescence, or efflux of time. Unlike commercial accounting where depreciation is computed asset-by-asset under Straight Line or WDV methods, the Income Tax Act mandates the "Block of Assets" system under the Written Down Value (WDV) method (except for power-generating units which possess a Straight Line option under Section 32(1)(i)).
Concept of "Block of Assets"
A "Block of Assets" means a group of assets falling within a class of assets comprising:
1. Tangible Assets
Buildings, Machinery, Plant, Furniture, and Fittings.
2. Intangible Assets
Know-how, patents, copyrights, trademarks, licenses, franchises, or any other commercial rights of similar nature (acquired on or after 01-04-1998; goodwill of a business is explicitly excluded).
Core Requirement: To constitute a valid block, all assets within the class must carry the exact same statutory percentage rate of depreciation.
Three Cumulative Statutory Conditions for Claiming Depreciation
Ownership of Asset
The asset must be owned (wholly or partly) by the assessee. Where a tenant incurs capital expenditure on leased premises for renovation or construction, Section 32(1) allows depreciation to the tenant as deemed owner.
Used for Business / Profession
The asset must be used for the purposes of the assessee's business or profession during the previous year. Judicial decisions affirm that "use" includes both active use and passive use (standby generators, fire-fighting equipment kept ready for deployment).
Mandatory Allowance
Under Explanation 5 to Section 32(1), depreciation allowance is mandatory. An assessee cannot forego or defer depreciation to manipulate book profits or carry forward allowances artificially.
Where an asset is acquired by the assessee during the previous year and is put to use for the purposes of business for a period of less than 180 days in that previous year, the depreciation deduction in respect of such asset is strictly restricted to 50% of the prescribed depreciation rate.
Practical Calendar Rule: In a standard financial year (April 1 to March 31), any asset acquired and put to use on or after October 4th (or October 3rd in a leap year) is used for less than 180 days and is restricted to half the normal rate.
Statutory Depreciation Rates Table [Income Tax Rules]
| Class of Asset | Sub-Category / Description of Assets | Statutory Rate |
|---|---|---|
| I. Buildings | Purely residential buildings (excluding hotels and boarding houses) | 5% |
| Commercial buildings, office premises, factories, hotels, godowns, warehouses | 10% | |
| Purely temporary erections, wooden structures | 40% | |
| II. Furniture & Fittings | General furniture, office fixtures, electrical fittings, partitions | 10% |
| III. Plant & Machinery | General Plant and Machinery (standard commercial rate) | 15% |
| Motor cars used for business (commercial running/hiring taxi business: 30%) | 15% / 30% | |
| Computers, laptops, and computer software | 40% | |
| Pollution control equipment, renewable energy devices, books | 40% | |
| IV. Intangible Assets | Patents, copyrights, trademarks, licenses, franchises, technical know-how | 25% |
Additional Depreciation (20% / 35%)
To incentivize industrial capital investments and manufacturing modernization, Additional Depreciation is granted over and above normal depreciation:
Eligibility & Rates
• Eligible Assessees: Engaged in the manufacture or production of any article/thing, or in generation, transmission, or distribution of power.
• Eligible Asset: Any NEW plant and machinery acquired and installed during the year.
• Standard Rate: Flat 20% of actual cost.
• Enhanced Rate (35%): If installed in notified backward areas of Andhra Pradesh, Bihar, Telangana, or West Bengal.
Special Operational Rules
• Half-Rate Carry Forward Rule: If new machinery is put to use for less than 180 days, additional depreciation of 10% (half of 20%) is allowed in the year of acquisition, and the remaining 10% balance is carried forward and allowed in the immediately succeeding financial year!
• Ineligible Assets: Ships, aircraft, second-hand machinery, machinery installed in office/guest house, office appliances, and road transport vehicles.
4. Allowable Deductions under Sections 30 to 37 [Unit 21 & Unit 22]
The statutory architecture provides specific deductions under Sections 30 through 36, capped by a residuary omnibus deduction under Section 37(1).
Rent, Rates, Taxes & Repairs of Buildings
Deduction allowed for rent paid by tenant, municipal rates and taxes, current repairs, and insurance premium against risk of damage. Limitation: Capital expenditure on expansion or structural reconstruction is strictly disallowed.
Repairs & Insurance of Machinery, Plant & Furniture
Deduction allowed for current revenue repairs (incurred to preserve and maintain the asset in operational order) and insurance premiums paid against fire/damage. Cost of replacing entire machinery is capital in nature.
Expenditure on Scientific Research
Section 35 provides accelerated tax deductions to foster technological innovation and scientific inquiry:
In-House Research [Sec 35(1)(i) & (iv)]
100% deduction for both revenue expenditure and capital expenditure incurred on research related to the business. Full capital expenditure is deductible in the year incurred (excluding cost of acquisition of land).
Pre-Commencement Expenses
Revenue expenses on salaries and materials, and capital expenditure incurred within 3 years prior to commencement of business, are fully deductible (100%) in the year business commences.
Contributions to Outside Bodies
100% deduction for sums paid to approved scientific research associations, universities, colleges, IITs, or National Laboratories.
Amortization of Preliminary Expenses
Indian companies and resident non-corporate taxpayers are entitled to amortize specified preliminary expenditures incurred before business commencement or in connection with enterprise extension:
Eligible Expenses
Feasibility reports, market survey reports, engineering services, drafting MOA & AOA, ROC registration fees, and public issue underwriting commissions.
Amortization Period
Deductible in 5 equal annual installments (1/5th each year for 5 consecutive previous years).
Statutory Ceiling Cap
Aggregate eligible expenses cannot exceed 5% of Cost of Project (or 5% of Capital Employed for Indian companies, whichever is higher).
Specific Deductions under Section 36
| Section | Nature of Expenditure | Statutory Conditions & Constraints |
|---|---|---|
| Sec 36(1)(i) | Insurance of Stock-in-Trade | Premium paid against risk of damage or destruction of commercial stocks or stores. |
| Sec 36(1)(ii) | Bonus or Commission to Employees | Paid for services rendered; allowable on actual payment basis under Section 43B. |
| Sec 36(1)(iii) | Interest on Borrowed Capital | Borrowed for business purpose. Interest on loans for asset acquisition up to the date asset is put to use must be capitalized! |
| Sec 36(1)(iv)/(v) | Employer's PF / Gratuity Contribution | Contribution to Recognized Provident Fund or approved gratuity fund; subject to Section 43B payment rules. |
| Sec 36(1)(va) | Employee's Contribution to PF / ESI | Deductible ONLY if deposited on or before the due date under the PF/ESI Acts. If deposited late, 100% disallowed permanently! |
| Sec 36(1)(vii) | Bad Debts Written Off | Debt must be written off as irrecoverable in books; must have been taken into account in computing income. Mere provision is not allowed! |
| Sec 36(1)(xv) | Securities / Commodities Transaction Tax | STT and CTT paid in the ordinary course of share or commodity trading business. |
General / Residuary Deduction [Unit 22]
Section 37(1) acts as the omnibus residuary clause allowing deduction for all legitimate business expenditures not covered under Sections 30 to 36. An expenditure is deductible under Section 37(1) only if it fulfills four cumulative statutory tests:
Must not be covered by specific items in Sections 30–36.
Must not be in the nature of capital expenditure.
Must not represent personal expenses of proprietor/directors.
Incurred wholly and exclusively for business purposes.
Statutory Negative List / Prohibitions under Section 37
5. Specific Statutory Disallowances [Sections 40, 40A, and 43B]
The Income Tax Act contains strict overriding provisions that disallow certain expenditures even if they are genuine and incurred for business purposes:
Amounts Statutorily Not Deductible
• Non-Residents [Sec 40(a)(i)]: 100% of interest, royalty, or fees paid outside India or to a non-resident is disallowed if TDS is not deducted or not deposited within due date.
• Residents [Sec 40(a)(ia)]: 30% of payments made to residents (interest, commission, professional fees, contractor payments) is disallowed if TDS is not deducted. Allowed in subsequent year upon deposit.
• Direct Taxes [Sec 40(a)(ii)]: Income Tax, wealth tax, surcharge, or Health & Education Cess is strictly non-deductible.
• Remuneration to Partners [Sec 40(b)]: Non-working partners: 100% disallowed. Working partners: allowed up to deed limits: on first ₹3,00,000 book profit: ₹1,50,000 or 90%; balance: 60%. Simple interest on capital capped at 12% p.a.
Expenses Disallowable in Specific Circumstances
Where payment is made to specified persons (relatives, partners, directors, entities holding > 20% voting power), the Assessing Officer has statutory power to disallow the expenditure to the extent it is excessive or unreasonable compared to fair market value.
Where aggregate payments to a person in a single day exceed ₹10,000 otherwise than by account payee cheque, bank draft, or electronic clearing system (NEFT/RTGS/UPI), 100% of the expenditure is disallowed! (Relaxed to ₹35,000 for payments to goods carriage operators).
Statutory Deductions Allowed Strictly on Actual Payment Basis
Section 43B mandates that the following expenditures are deductible only in the previous year in which they are actually paid, regardless of the mercantile accounting method:
Proviso to Section 43B: These 6 items are allowable in the accrual year provided payment is made on or before the due date of filing the income tax return under Section 139(1).
Section 43B(h) mandates that any sum payable to a Micro or Small Enterprise beyond the time limit specified in Section 15 of the MSMED Act, 2006 (i.e., within 15 days, or up to 45 days under written agreement), is allowable ONLY in the year of actual payment.
Crucial Difference: Unlike other Section 43B items, the concession of paying up to the return filing date u/s 139(1) DOES NOT APPLY to Section 43B(h)! If payment is delayed past the MSMED deadline, the deduction is compulsorily disallowed in that financial year and can only be claimed in the year of actual payment.
6. Presumptive Taxation Regimes [Sections 44AD, 44ADA, & 44AE] & Tax Audit [Section 44AB]
To relieve small taxpayers from the burdensome maintenance of books of accounts under Section 44AA and tax audits under Section 44AB, the Income Tax Act provides special presumptive taxation schemes:
| Scheme Parameter | Section 44AD (Small Business) | Section 44ADA (Professionals) | Section 44AE (Transporters) |
|---|---|---|---|
| Eligible Assessee | Resident Individual, HUF, Partnership Firm (excluding LLP) | Resident Individual, Partnership Firm (excluding LLP) in specified professions | Any assessee owning not more than 10 goods vehicles at any time in the year |
| Gross Turnover Limit | Up to ₹2 Crores (raised to ₹3 Crores if cash receipts ≤ 5%) | Up to ₹50 Lakhs (raised to ₹75 Lakhs if cash receipts ≤ 5%) | Assessee owning ≤ 10 goods carriages at any time during the year |
| Presumed Net Income Rate | 8% of turnover (reduced to 6% for digital/banking turnover) | Minimum 50% of gross professional receipts | Heavy Vehicle (> 12T): ₹1,000/ton/month; Other Vehicles: ₹7,500/vehicle/month |
| Deductions u/s 30 to 38 | Deemed fully allowed; no further deduction | Deemed fully allowed; no further deduction | Deemed fully allowed; no further deduction |
Compulsory Tax Audit Thresholds
Business Tax Audit
• Mandatory if total turnover/gross receipts exceed ₹1 Crore.
• Raised to ₹10 Crores if aggregate cash receipts and cash payments do not exceed 5% of total transactions.
Profession Tax Audit
• Mandatory if gross professional receipts exceed ₹50 Lakhs.
• Raised to ₹75 Lakhs if cash receipts do not exceed 5% of gross receipts.
7. Practical Computation of Income from Business [Unit 23]
