Income under the Head Salary for CS Executive

Income under the Head Salary covers what an employee receives from an employer: pay, allowances, perquisites, retirement benefits and profits in lieu of salary. You solve it by adding taxable items, subtracting allowed deductions, and showing the result as taxable salary, with the Income-tax Act, 2025 provision cited where it matters.

What this chapter covers

This chapter teaches you how an employee's earnings from an employer are taxed. You first learn what counts as salary and when it is charged. Then you study each component: allowances, perquisites, profits in lieu of salary, and retirement benefits such as gratuity, leave salary and pension. The chapter ends with deductions and the final computation of taxable salary.

It is a computation-heavy chapter. Most questions give you a set of payments and ask you to find taxable salary. You need to decide for each item whether it is fully taxable, partly exempt or fully exempt, and then add them up in a clear format.

The chapter links to the rest of Paper 7 Part I. Taxable salary flows into gross total income, where it combines with income from other heads. It also connects to residential status, because the place where salary is earned or received affects its charge. For June 2027, you study it under the Income-tax Act, 2025 as amended by the Finance Act, 2026, so use the tax year and the new section numbers, not the old assessment year language.

Salary is the head almost every working person has, so examiners like it for practical, number-based questions. Each question tests several rules at once: allowances, perquisites, retirement benefits and deductions. If you learn the rules in a fixed order and practise a clean format, you can score well here, and the same discipline helps in later heads. Because you write descriptive answers, you also need to state the provision and give a clear conclusion, not just a figure.

Income under the Head Salary: topics in the order to study them

1Meaning of Salary and Basis of ChargeStart here because it defines what is salary, who is an employer and employee, and when salary is charged. Every later topic depends on these ideas.
2Allowances and Their TaxabilityAllowances are the simplest components to compute. They teach you the habit of testing each item for full, partial or nil taxability.
3Perquisites and ValuationThis is the largest and most tested part. Study it after allowances so you can separate cash allowances from benefits in kind and then learn the valuation rules.
4Profits in Lieu of Salary and Accumulated BalancesThese are smaller, rule-based items. Learn them once you know the normal salary components, so you see how they differ.
5Retirement Benefits: Gratuity, Leave Salary and PensionThese need separate exemption calculations and depend on the type of employer and employee. They come after the basics so you can focus on the formulas.
6Deductions from Salary and Computation of Taxable SalaryThis is the final step. It pulls every earlier topic into one computation, so study it last and use it for full practice questions.

How to prepare Income under the Head Salary

Treat this chapter as a checklist you apply to every question. Build the checklist first, then practise until it is automatic.

Read the basis of charge and definitions once, and write a one-page summary of what is salary and when it is taxable.
For allowances and perquisites, make a table of each item with its rule: fully taxable, partly exempt or exempt. Learn it by item, not by passage.
Learn each valuation and exemption formula with one small worked example. Redo the example from memory the next day.
Read the employer-welfare deduction in section 29 of the Income-tax Act, 2025, so you know which employer contributions are allowed and why.
Solve full computation questions in a fixed format: gross salary, less exemptions, less deductions, taxable salary. Do at least a few every week.
In every answer, write the provision, apply it to the facts, and end with a clear conclusion on taxable amount.
Revise your tables and formulas weekly, and time yourself on one computation question before the exam.

Common mistakes in Income under the Head Salary

Using the Income-tax Act, 1961 section numbers and terms for a June 2027 answer.
Fix: Use the Income-tax Act, 2025 and the term tax year. Check every section number against the 2025 Act before you write it.
Adding an allowance in full without testing whether it is exempt.
Fix: Run each allowance through your table of rules before adding it to gross salary.
Mixing up employer deductions with employee deductions.
Fix: Note who the assessee is in each rule. Section 29 applies to the employer in computing its own income.
Treating any provision for gratuity as deductible.
Fix: Remember that under section 29(2) a provision is generally disallowed, with an exception in section 29(1)(d) for approved fund contributions or gratuity that became payable in the tax year.
Giving only a number without the provision or conclusion.
Fix: Write the rule, apply it to the facts, then state the conclusion in words as well as in figures.

Last-day revision: Income under the Head Salary

Salary includes pay, allowances, perquisites, annuities and retirement benefits received from an employer.
Test every item as fully taxable, partly exempt or fully exempt before adding it.
Perquisites are benefits in kind. Know who is taxed on them and how each is valued.
Profits in lieu of salary are payments linked to the job, such as compensation on termination.
Gratuity, leave salary and pension each have their own exemption rules. Check the type of employer.
Under section 29(1)(a), an employer's contribution to a recognised provident fund or approved superannuation fund is deductible, within prescribed limits.
Under section 29(1)(b), an employer's contribution to a pension scheme for an employee is deductible up to 14% of salary, which includes dearness allowance only if the terms of employment so provide.
Under section 29(1)(c), contributions to an approved gratuity fund held under an irrevocable trust are deductible.
Under section 29(2), a provision for gratuity is generally not deductible, except under section 29(1)(d). If allowed under (1)(d), the actual payment is not deducted again.
Use the tax year and the Income-tax Act, 2025 for June 2027, not the 1961 Act.
End each computation with a clear taxable salary figure and a one-line conclusion.

Income under the Head Salary: frequently asked questions

Is Income under the Head Salary important for CS Executive?

Yes. It sits in Paper 7 Part I on Direct Tax, and it tests computation and legal reasoning together. It also feeds into gross total income, so the skills carry into other heads.

Which Act should I study this chapter under for June 2027?

Study the Income-tax Act, 2025 as amended by the Finance Act, 2026, for tax year 2026-27. The December 2026 session uses the Income-tax Act, 1961 instead, so do not mix the two.

Do I need to memorise section numbers?

Learn the key ones and cite them where they matter, such as section 29 for employer deductions. Do not guess a number. If you are unsure, state the rule clearly in words.

Can an employer deduct a provision for gratuity?

Generally not. Under section 29(2), no deduction is allowed for a provision for gratuity on retirement or termination, except as section 29(1)(d) allows. That clause covers provision for contribution to an approved gratuity fund or for gratuity that became payable in the tax year.

How do I practise this chapter best?

Build rule tables first, then solve full computation questions in a fixed format. Write the provision and a conclusion each time, because the paper is descriptive and you are marked on both.
