Section 15 Income Tax Act: Complete Guide to Salaries Chargeable to Tax

Learn What Income Is Chargeable Under Section 15  Income Tax Act 1961. Understand Due Basis Vs Receipt Basis, Advance Salary, Arrears, And Tax Computation

Have you ever wondered why your March salary gets taxed even if your employer delays paying it until April? Or why receiving a bonus from last year in your current paycheck affects this year’s taxes? If you’re a salaried employee in India, understanding Section 15 of the Income Tax Act, 1961 isn’t just legal jargon—it’s essential knowledge that directly impacts how much tax you pay and when.

Whether you’re filing your first Income Tax Return (ITR) or optimizing your tax planning strategy, this guide breaks down exactly what income falls under the head “Salaries,” how the timing of taxation works, and what deductions you can claim. Let’s dive into the legal framework that governs how your hard-earned money gets taxed.

What Is Section 15 and Why Does It Matter?

Section 15 is the charging section for income under the head “Salaries.” In simple terms, it tells us when and what salary income becomes taxable. According to the official legal text, the following income is chargeable to income-tax under the head “Salaries” :

1. Any salary due from an employer (or former employer) in the previous year, whether paid or not
2. Any salary paid or allowed in the previous year, even if it wasn’t due or was paid before it became due
3. Any arrears of salary paid in the previous year, if they weren’t charged to tax in any earlier year

The Golden Rule: Salary is taxable on “due basis” or “receipt basis, whichever is earlier.” This means you can’t escape taxation simply because your employer delays payment or you choose to defer receiving it .

Key Takeaway: The taxman follows your salary’s timeline, not just your bank account balance. Understanding this “earlier of due or receipt” principle is crucial for accurate tax planning.

The Three Scenarios: Breaking Down Section 15 Clauses

1. Salary Due But Not Paid (Clause a)

Imagine you work for a company that faces cash flow issues. Your salary for March 2025 is due on March 31st, but the company pays you on April 15th, 2025. Guess what? That salary is still taxable in the financial year 2024-25 (Assessment Year 2025-26) because it became due in March, even though you received it in April .

Why this matters: Employers cannot defer tax liability by delaying payments. The tax liability attaches to the due date, not the payment date.

2. Advance Salary (Clause b)

Now, let’s flip the scenario. Suppose your employer pays you June 2025’s salary in advance during May 2025. Even though this salary isn’t technically “due” yet, it’s taxable in the year you receive it (FY 2025-26) .

Important Protection: Explanation 1 to Section 15 ensures you’re not taxed twice. If you paid tax on advance salary in Year 1, you won’t pay tax again when it becomes actually due in Year 2 .

3. Arrears of Salary (Clause c)

You finally receive that pending bonus for FY 2023-24 in June 2024. Since this wasn’t taxed earlier when it was due, it becomes taxable in the year of receipt (FY 2024-25) .

Tax Relief Available: If arrears push you into a higher tax bracket for the current year, you can claim relief under Section 89 to avoid paying excessively high taxes due to timing issues .

The Foundation: Employer-Employee Relationship

Before any income can be taxed as “Salary,” there must exist a master-servant relationship between the payer and payee. This isn’t just about having a job—it’s a specific legal concept.

What counts as Salary:

• Payments from current employers
• Payments from former employers (like gratuity, pension, or pending dues)
• Regular wages, bonuses, commissions, and allowances

What does NOT count as Salary:

• Partner’s remuneration: If you’re a partner in a firm, any salary, bonus, or commission you receive from that firm is taxed under “Profits and Gains of Business or Profession,” not as Salary
• Consultancy fees: Freelancers and independent consultants don’t earn “salary”—they earn business income
• Contractual payments without employment: Just because someone pays you regularly doesn’t make it salary if there’s no employer-employee relationship

Case Law Insight: In CIT v. L.W. Russel, the Supreme Court emphasized that the existence of an employer-employee relationship is essential for income to be taxed under Salaries. Without this relationship, the same payment might fall under different tax heads .

Components of Salary Income: Beyond Basic Pay

When we talk about “salary” under Section 15, we’re not just referring to your monthly basic pay. Section 17(1) defines salary inclusively to cover :

Computing Your Taxable Salary: The Step-by-Step Formula

Now that you know what constitutes salary income, let’s look at how to calculate what’s actually taxable :

Step 1: Calculate Gross Salary

Basic Salary

+ Dearness Allowance

+ Taxable Allowances (HRA taxable portion, Special Allowance, etc.)

+ Bonus/Commission

+ Perquisites (taxable value)

+ Profits in Lieu of Salary

+ Advance Salary (if received)

+ Arrears of Salary (if received and not taxed earlier)

= GROSS SALARY

Step 2: Claim Exemptions Under Section 10

Certain portions of your salary are exempt from tax:

• HRA exemption (if you pay rent and have the receipts)
• Leave Travel Concession (LTC) under Section 10(5)
• Gratuity exemption under Section 10(10)
• Leave Encashment under Section 10(10AA) (for government employees)
• Pension exemptions

Step 3: Claim Deductions Under Section 16

From your Gross Salary (after exemptions), you can deduct :

Step 4: Arrive at Taxable Salary

Gross Salary

– Exemptions under Section 10

– Deductions under Section 16

= NET TAXABLE SALARY (Chargeable to Tax)

Example Calculation:

For Example: Meet Priya, a marketing manager with the following details for FY 2024-25:

• Basic Salary: ₹8,00,000
• DA: ₹2,00,000
• HRA received: ₹3,00,000 (She pays rent of ₹2,40,000 in metro city)
• Special Allowance: ₹1,00,000
• Bonus: ₹50,000
• Professional Tax paid: ₹2,400

Computation:

1. Gross Salary: ₹8,00,000 + ₹2,00,000 + ₹3,00,000 + ₹1,00,000 + ₹50,000 = ₹14,50,000
2. HRA Exemption: Least of:

• Actual HRA received: ₹3,00,000
• Rent paid minus 10% of salary: ₹2,40,000 – ₹1,00,000 = ₹1,40,000
• 50% of salary (metro): ₹5,00,000
• Exemption = ₹1,40,000

3. Gross Salary after exemption: ₹14,50,000 – ₹1,40,000 = ₹13,10,000
4. Less: Standard Deduction: ₹50,000
5. Less: Professional Tax: ₹2,400
6. Net Taxable Salary: ₹13,10,000 – ₹50,000 – ₹2,400 = ₹12,57,600

Common Mistakes to Avoid When Reporting Salary Income

Even seasoned taxpayers make these errors. Here’s what to watch out for :

1. Declaring income in the wrong year: Remember the “due or receipt, whichever is earlier” rule. Don’t shift March salary to the next FY just because it hit your bank in April.
2. Ignoring Form 16 details: Your Form 16 (Part B) breaks down your salary components. Cross-verify every number with your salary slips before filing ITR.
3. Forgetting arrears in current year: If you receive past dues, include them in the current year’s income and claim Section 89 relief if applicable.
4. Missing standard deduction: Don’t forget to claim the flat ₹50,000 deduction—it’s automatic for all salaried employees.
5. Confusing gross vs. net salary: Tax is calculated on gross salary minus exemptions and deductions, not just what lands in your bank account.

Frequently Asked Questions (FAQ)

Q1: Is my March salary taxable if I receive it in April?

A: Yes. If the salary was due in March (end of financial year), it’s taxable in that financial year regardless of when you actually receive it. This follows the “due basis” rule under Section 15.

Q2: Can I be taxed twice on the same salary—once as advance and once when it becomes due?

A: No. Explanation 1 to Section 15 specifically prevents double taxation. If you paid tax on advance salary in Year 1, it won’t be taxed again when it becomes due in Year 2 .

Q3: What happens if I receive salary arrears from previous years?

A: Arrears are taxable in the year you receive them, unless they were already taxed when they became due. However, you can claim relief under Section 89 to avoid higher tax rates due to bunching of income .

Q4: Is pension from a former employer taxable as salary?

A: Pension received from a former employer is generally taxable under the head “Salaries.” However, certain exemptions may apply under Section 10(10A) for commuted pension .

Q5: Do freelancers and consultants fall under Section 15?

A: No. Freelancers, consultants, and independent professionals don’t have an employer-employee relationship. Their income is taxed under “Profits and Gains of Business or Profession” or “Income from Other Sources,” not as Salary .

Conclusion: Master Your Salary Taxation

Understanding Section 15 of the Income Tax Act empowers you to plan your finances better and avoid compliance headaches. Remember these key takeaways:

• Timing is everything: Salary is taxed when it’s due OR when received, whichever happens first
• Relationship matters: Only employer-employee payments qualify; partner drawings and freelance income go elsewhere
• Don’t miss deductions: Standard deduction of ₹50,000 is available to everyone, plus professional tax and entertainment allowance for eligible employees
• Arrears have relief: Section 89 can save you from higher taxes when receiving past dues
• Documentation is key: Always match your ITR with Form 16 and salary slips

Tax laws might seem complex, but they’re built on logical principles. Once you grasp the “earlier of due or receipt” concept and understand what constitutes a true employer-employee relationship, navigating salary taxation becomes much clearer.

What’s your biggest confusion when it comes to salary taxation? Is it the timing rules, the various allowances, or figuring out which deductions you can claim? Understanding these basics not only helps you file accurate returns but also empowers you to have informed discussions with your HR and tax advisors about optimizing your salary structure.
