Section 4 of the Income-tax Act, 1961 is the fundamental charging section that imposes income tax on the total income earned by every taxable person during a previous year. Under Section 4(2), the statute mandates the collection of tax through withholding at the point of payment (Tax Deducted at Source) and advance tax payments.
Section 4: The Statutory Foundation of Income Tax in India
In Indian taxation law, a tax cannot be assessed or collected without clear statutory authority as mandated by Article 265 of the Constitution of India. Section 4 of the Income-tax Act, 1961 serves as the master charging section that brings the entire machinery of direct taxation into operation. The provision establishes that where any central enactment, such as the annual Union Finance Act, prescribes rates of income tax for an assessment year, tax shall be charged in respect of the total income of the previous year of every person.
The charging section operates in conjunction with Section 5, which defines the scope of total income based on residential status, and Section 14, which categorizes income under five distinct heads: salaries, house property, profits and gains of business or profession, capital gains, and income from other sources. Without the charging mandate under Section 4, no assessment, recovery, or penalty proceedings can be sustained under the Act.
Key Tax Concepts: Previous Year, Assessment Year, and Taxable Person
To understand the application of Section 4, three legal definitions under the Act are central:
- Previous Year (Section 3): The financial year immediately preceding the assessment year during which income is actually earned by the taxpayer.
- Assessment Year (Section 2(9)): The twelve month period starting on 1 April following the previous year, during which the income earned is assessed, reported, and taxed.
- Person (Section 2(31)): The taxable entity, including individuals, Hindu Undivided Families (HUF), companies, partnership firms, associations of persons, bodies of individuals, local authorities, and artificial juridical persons.
While tax is charged on the total income of the previous year, the proviso to Section 4(1) creates statutory exceptions where tax is charged on income of the current period itself. These exceptions include the shipping business of non-residents (Section 172), persons leaving India permanently (Section 174), bodies formed for short duration (Section 174A), persons transferring property to avoid tax (Section 175), and discontinued business entities (Section 176).
The Mechanism of Tax Deducted at Source (TDS) under Section 4(2)
Section 4(2) explicitly provides that in respect of income chargeable under Section 4(1), income tax shall be deducted at source or paid in advance wherever mandated by any provision of the Act. This statutory provision operationalizes Chapter XVII-B of the Act, which imposes a mandatory legal obligation on payers (deductors) to withhold a specified percentage of tax before disbursing funds to recipients (deductees).
TDS serves three vital economic and administrative purposes in direct tax administration:
- Continuous Revenue Flow: It provides the government with regular tax receipts throughout the financial year rather than a single lump sum at year end.
- Audit Trail and Tax Compliance: It creates an unalterable reporting trail that prevents tax evasion, underreporting, and unrecorded cash transactions.
- Convenience for Assessees: It distributes the tax burden of assessees across periodic deductions rather than imposing a heavy year end liability.
Corporate enterprises managing multi-tiered vendor payments and cross-border commercial transactions frequently utilize outsourced general counsel services for corporate tax compliance to ensure statutory withholding deadlines and regulatory schedules are strictly observed.
Common Categories of TDS under Chapter XVII-B
The Income-tax Act specifies dedicated sections for different types of payments, establishing distinct thresholds and deduction rates:
| Section | Nature of Payment | Standard Threshold | Standard Rate |
|---|---|---|---|
| Section 192 | Salaries | Basic exemption limit | Average income tax slab rate |
| Section 194A | Interest other than securities | INR 40,000 (INR 50,000 for seniors) | 10% |
| Section 194C | Payments to contractors | INR 30,000 single / INR 1,00,000 aggregate | 1% (Individual/HUF) / 2% (Other) |
| Section 194H | Commission or brokerage | INR 15,000 per financial year | 5% |
| Section 194I | Rent on land, building, or furniture | INR 2,40,000 per financial year | 10% (Plant/machinery 2%) |
| Section 194J | Professional or technical services | INR 30,000 per financial year | 10% (2% for technical fees) |
| Section 195 | Payments to non-residents | No minimum threshold | Applicable DTAA or statutory rate |
Obligations of Deductors and Rights of Deductees
Every entity responsible for deducting tax at source must obtain a Tax Deduction and Collection Account Number (TAN) under Section 203A. The deductor is legally obligated to deposit the deducted tax to the credit of the Central Government by the seventh day of the subsequent month. In addition, deductors must file quarterly TDS returns (Form 24Q for salaries, Form 26Q for non-salary domestic payments, Form 27Q for non-resident payments) and issue TDS certificates (Form 16/16A) to the deductees within statutory timelines.
Quarterly return filing schedules require submission by 31 July for the first quarter, 31 October for the second quarter, 31 January for the third quarter, and 31 May for the final quarter. Deductors failing to file returns on time face late filing fees under Section 234E of INR 200 per day of delay.
For the recipient, tax deducted at source is deemed to be income received under Section 198 and constitutes a direct credit against their final tax liability under Section 199. When the annual income tax return is filed, the tax credits reflected in Form 26AS and the Annual Information Statement (AIS) are adjusted against total liability, resulting in a net tax payable or a tax refund with interest.
Where a payee expects total income to remain below taxable limits, statutory relief can be sought by submitting Form 15G or Form 15H under Section 197A, or by obtaining a lower or nil deduction certificate from the Assessing Officer under Section 197.
Failure to deduct or deposit TDS attracts stringent consequences, including mandatory interest under Section 201(1A), financial penalty under Section 271C, prosecution under Section 276B, and statutory disallowance of thirty percent of the business expenditure under Section 40(a)(ia). Compliance with fiscal withholding provisions remains as foundational as commercial contract enforcement and statutory obligations across corporate and commercial operations.
