Sections 15-17 Guide : Learn How To Compute Income From Salaries Under India’s Income Tax Act. Discover Standard Deductions, Allowances, Perquisites & Save Taxes Legally.

Introduction

Have you ever looked at your salary slip and wondered, “Why am I paying tax on the full amount when I never received some of these benefits in cash?” Or perhaps you’ve received a Form 16 from your employer and felt overwhelmed by the numbers?

You’re not alone. Every year, millions of salaried employees in India struggle to understand how their salary income is actually calculated for tax purposes. The good news? Once you understand the basic framework under Sections 15, 16, and 17 of the Income Tax Act, 1961, computing your salary income becomes straightforward.

This guide breaks down the entire process into simple, digestible steps—no accounting degree required. Whether you’re a fresher filing your first ITR or a seasoned professional optimizing your tax savings, this article will help you master the computation of income under the head ‘Income from Salaries.’

What Counts as “Salary” Under Indian Tax Law?

The Employer-Employee Relationship: The Foundation

Before diving into numbers, here’s the golden rule: Income is taxed as “Salary” only when there’s an employer-employee relationship . This means:

• Freelancers working for multiple clients? Not salary income—that’s “Business or Profession.”
• Partners taking money from their own firm? Not salary—that’s treated as business income .
• You receiving monthly pay from your company? That’s salary.

Section 17(1): The Broad Definition of Salary

Section 17(1) gives an inclusive definition of salary—meaning it’s wider than what you see in your bank account . Your taxable salary includes:

For Example: Raj receives ₹50,000 basic salary, ₹10,000 HRA, a company car, and ₹5,000 medical allowance. For tax purposes, his “salary” isn’t just ₹50,000—it includes the taxable value of that car and other allowances too.

Section 15: When Is Your Salary Taxed?

Here’s where timing matters. Section 15 establishes the basis of charge—essentially, when does the taxman consider your income as earned ?

The “Due or Receipt, Whichever is Earlier” Rule

Your salary is taxable in the year it becomes due to you OR when you actually receive it—whichever happens first .

Three Scenarios:

1. Salary Due but Not Paid: Your March 2024 salary is due on March 31, 2024, but your company pays it on April 5, 2024. It’s taxable in FY 2023-24 (the year it became due).
2. Salary Paid Before It’s Due: Your employer pays June’s salary in May as an advance. It’s taxable in FY 2024-25 when received, even though it’s not technically “due” yet.
3. Arrears: You receive back-pay for 2022-23 in 2024-25. If it wasn’t taxed earlier, it’s taxable now. If already taxed when due, it’s not taxed again .

Key Takeaway: You cannot escape taxation by simply delaying payment. The law catches income on an accrual basis.

Section 16: Deductions That Reduce Your Taxable Salary

Now for the good part—deductions. Section 16 allows you to subtract specific amounts from your gross salary before calculating tax . Think of these as “expenses” the government acknowledges you incur to earn your salary.

1. Standard Deduction [Section 16(ia)]: The No-Questions-Asked Relief

The standard deduction is the most significant benefit for salaried individuals. Introduced in 2018, it replaced the old system of transport and medical allowances .

Why This Matters:

• No receipts required—unlike other deductions, you don’t need to submit bills or proof.
• Automatic application—your employer deducts it while calculating TDS.
• Pensioners eligible—if you receive pension, it’s treated as salary and qualifies for this deduction .

For Example: Priya earns ₹8,00,000 gross salary. Under the old regime, she automatically gets ₹50,000 deducted, making her taxable salary ₹7,50,000. Under the new regime, she’d get ₹75,000 deducted, resulting in ₹7,25,000 taxable salary.

2. Entertainment Allowance [Section 16(ii)]: Only for Government Employees

This deduction is exclusive to Central and State Government employees . If you work in the private sector, skip this section.

Calculation: The deductible amount is the least of:

• ₹5,000
• 20% of basic salary (excluding allowances)
• Actual entertainment allowance received

For Example: A government officer with ₹6,00,000 basic salary receives ₹15,000 as entertainment allowance. The deduction would be the least of:

• ₹5,000
• 20% of ₹6,00,000 = ₹1,20,000
• ₹15,000

Result: ₹5,000 deduction allowed.

3. Professional Tax [Section 16(iii)]: State-Level Employment Tax

Some states levy professional tax (also called tax on employment) under Article 276(2) of the Constitution . The maximum allowed is ₹2,500 per year.

Important Rules:

• If you paid it directly to the state government → Deduct the full amount.
• If your employer paid it and deducted from your salary → The amount is first added to your salary as a perquisite, then you claim the deduction .

States Charging Professional Tax: Karnataka, Maharashtra, Tamil Nadu, West Bengal, and others (varies by state laws).

Allowances: Taxable, Exempt, and Partially Exempt

Allowances are specific amounts paid by employers to cover particular expenses. They’re categorized based on tax treatment :

Fully Taxable Allowances

These get added entirely to your gross salary:

• City Compensatory Allowance
• Overtime Allowance
• Dearness Allowance (when not part of retirement benefits)
• Interim Allowance

Partially Exempt Allowances (The Tax-Savers)

Fully Exempt Allowances

• Transport allowance for handicapped employees (up to ₹3,200/month)
• Allowances to UN employees
• Compensatory allowance to High Court/Supreme Court judges

For Example: Neha works in Mumbai with:

• Basic: ₹12,00,000/year
• HRA received: ₹6,00,000/year
• Rent paid: ₹4,80,000/year (₹40,000/month)

HRA Exemption Calculation:

1. Actual HRA: ₹6,00,000
2. 50% of salary (metro): ₹6,00,000
3. Rent paid – 10% of salary: ₹4,80,000 – ₹1,20,000 = ₹3,60,000

Exempt HRA: ₹3,60,000 (least of the three) Taxable HRA: ₹6,00,000 – ₹3,60,000 = ₹2,40,000

Perquisites: When Benefits Become Taxable Income

Perquisites (or “perks”) are non-monetary benefits your employer provides. Section 17(2) defines these, and Rule 3 of the Income Tax Rules determines their taxable value .

Common Taxable Perquisites

Exempt Perquisites

• Medical facilities up to ₹15,000/year
• Tea/snacks during office hours
• Laptop/computer for official use
• Telephone/mobile for official use

For Example: Your employer provides a 1,800cc car with driver for both personal and official use. The taxable value added to your salary would be:

• Car: ₹2,400/month
• Driver: ₹900/month
• Annual taxable value: ₹3,300 × 12 = ₹39,600

Step-by-Step Computation of Income from Salary

Let’s put it all together with a practical example. Meet Arjun, a marketing manager in Delhi:

Arjun’s Salary Structure (FY 2024-25):

• Basic Salary: ₹15,00,000
• Dearness Allowance: ₹3,00,000
• HRA received: ₹7,50,000
• Special Allowance: ₹2,00,000
• LTA received: ₹50,000 (spent ₹30,000 on travel)
• Employer-provided rent-free flat (15% valuation): ₹2,70,000
• Professional tax paid: ₹2,400

Step 1: Calculate Gross Salary

Step 2: Apply Exemptions

• HRA exemption: ₹4,20,000 (calculated as least of actual, 50% salary, rent paid minus 10% salary)
• LTA exemption: ₹30,000 (actual travel cost)

Step 3: Calculate Gross Taxable Salary ₹30,70,000 – ₹4,20,000 – ₹30,000 = ₹26,20,000

Step 4: Apply Section 16 Deductions

Step 5: Net Income from Salaries ₹26,20,000 – ₹52,400 = ₹25,67,600

This ₹25,67,600 is what Arjun will report as “Income from Salaries” in his ITR.

Standard Deduction vs. Chapter VI-A Deductions: What You Need to Know

Many taxpayers confuse the standard deduction with other tax-saving investments. Here’s the critical difference :

Strategic Tip: You can claim both. The standard deduction reduces your salary income first. Then, Chapter VI-A deductions reduce your gross total income further. Maximize your 80C (PPF, ELSS, LIC) and 80D (health insurance) over and above the standard deduction.

Tax Regime Comparison: Where Does Salary Computation Fit?

With the new tax regime becoming the default, understanding how salary computation differs is crucial :

Decision Framework:

• If you have high rent (paying significant HRA) and 80C investments → Old regime usually better despite lower standard deduction.
• If you have minimal deductions → New regime’s higher standard deduction and lower tax rates win.
• For Example: Same Arjun from earlier:
• Old Regime: ₹25,67,600 salary income minus ₹1,50,000 (80C) minus ₹50,000 (80D) = ₹23,67,600 taxable. Tax: ~₹4,85,000
• New Regime: ₹30,70,000 gross minus ₹75,000 standard deduction = ₹29,95,000 taxable (no HRA/LTA exemptions). Tax: ~₹4,20,000

Despite losing HRA benefit, the new regime works better for Arjun because he saves ₹65,000 in tax.

Frequently Asked Questions (FAQs)

Q1: Can I claim the standard deduction if I worked for two employers in one year?

Yes. The standard deduction is a flat amount for the financial year, not per employer. Even if you switched jobs, you get ₹50,000 (old) or ₹75,000 (new) total for the year, not per employer .

Q2: Is leave encashment always taxable?

No. Leave encashment received during employment is fully taxable. However, leave encashment at retirement is exempt up to ₹25,00,000 (as per recent amendments) for non-government employees. Government employees get full exemption .

Q3: My employer didn’t deduct TDS. Do I still need to pay tax?

Absolutely. The responsibility to pay tax lies with you, the taxpayer. If your employer failed to deduct TDS, you must pay the tax when filing your return, plus interest if applicable. Always verify Form 26AS to ensure TDS credits match .

Q4: Can I claim both HRA exemption and home loan interest deduction?

Yes, if you meet conditions. You can claim HRA exemption for rent paid (if you live in a rented house) AND claim deduction under Section 24(b) for home loan interest (up to ₹2,00,000) for a self-occupied house property. However, if both properties are in the same city, you may need to justify the genuine need .

Q5: What happens if my actual work expenses exceed the standard deduction?

Nothing. The standard deduction is a fixed, flat deduction regardless of your actual expenditure. Whether you spend ₹10,000 or ₹1,00,000 on work-related expenses, you still get only ₹50,000 (or ₹75,000) deduction. You cannot claim additional amounts .

Conclusion: Master Your Salary Income Tax

Computing income from salaries isn’t rocket science—it’s a methodical process of:

1. Aggregating all salary components (Section 17)
2. Timing it correctly (Section 15)
3. Reducing it with allowable deductions (Section 16)
4. Optimizing between old and new tax regimes

The key takeaways for every salaried employee:

• Standard deduction is your automatic right—₹50,000 (old) or ₹75,000 (new).
• HRA and LTA exemptions require proper documentation (rent receipts, travel tickets).
• Perquisites have specific valuation rules—don’t ignore them.
• Professional tax is deductible if you paid it.
• Choose your tax regime wisely based on your actual deductions and investments.

Remember: Tax planning is not tax evasion. Understanding these provisions helps you pay exactly what you owe, not a rupee more. Keep your Form 16 handy, maintain records of rent receipts and investments, and file your ITR on time.
