Questions covered                      Topic categories                 Worked examples
Q1  What is income tax and who is liable to pay it?                                                      Basics

Income tax is a direct tax levied by the Government of India on income earned by individuals, HUFs, firms, and companies during a financial year (April 1 – March 31). An individual is liable to pay income tax if their total income exceeds the basic exemption limit — ₹2,50,000 for below-60, ₹3,00,000 for senior citizens (60–80 yrs), and ₹5,00,000 for super senior citizens (above 80 yrs) under the old regime. Under the new regime, the basic exemption is ₹4,00,000 for all individuals.

Example — liability check
Rahul, age 35, gross income ₹2,80,000
Basic exemption (old regime) ₹2,50,000
Taxable income ₹30,000
Tax @ 5% ₹1,500
Rebate u/s 87A (income < ₹5L) – ₹1,500
Tax payable ₹0

Rahul is technically liable but pays zero tax due to the 87A rebate.

 

Q2  What are the five heads of income?                                                                        Basics

All income is classified under five heads: (1) Salaries — wages, pension, perquisites; (2) Income from house property — rental income less deductions; (3) Profits and gains of business or profession; (4) Capital gains — profit from sale of assets; (5) Income from other sources — interest, dividends, winnings, etc. The total of all five heads (after set-off of losses) is the Gross Total Income.

Example — GTI computation for Priya
Salary income ₹9,00,000
Income from house property ₹1,20,000
Capital gains (STCG on shares) ₹40,000
Income from other sources (FD interest) ₹30,000
Gross total income (GTI) ₹10,90,000

Each head is computed separately; losses in one head may be set off against others (subject to rules).

 

Q3  How is taxable income computed step by step?                                                    Basics

Start with Gross Total Income (GTI) — the sum of all five heads. Then subtract Chapter VI-A deductions (80C, 80D, etc.) to arrive at Total Income (Taxable Income). Apply the slab rates, subtract rebate u/s 87A if eligible, add surcharge if applicable, and add 4% health & education cess to get the final tax liability.

Example — step-by-step for Amit (old regime)
Gross salary ₹12,00,000
Less: standard deduction (u/s 16) – ₹50,000
Income from salary ₹11,50,000
Less: 80C (PPF + ELSS) – ₹1,50,000
Less: 80D (health insurance) – ₹25,000
Taxable income ₹9,75,000
Tax on ₹9,75,000 ₹1,12,500
Add: 4% cess ₹4,500
Total tax ₹1,17,000

Standard deduction of ₹50,000 is deducted from salary before arriving at GTI under the old regime.

 

Q4  What is the financial year vs assessment year?                                                   Basics

The Financial Year (FY) is the year in which income is earned — April 1 to March 31. The Assessment Year (AY) is the following year in which the income is assessed and tax is filed. For example, income earned between April 1, 2025 and March 31, 2026 belongs to FY 2025-26 and is assessed in AY 2026-27.

Example — FY vs AY mapping
Income earned during Apr 2025 – Mar 2026
Financial Year FY 2025–26
Assessment Year AY 2026–27
ITR filing due date (salaried) 31 July 2026
Applicable slab rates FY 2025-26 rates

Always quote AY when filing returns; quote FY when referring to the year income was earned.

 

Q5  What is the rebate under section 87A?                                                                 Basics

Section 87A provides a tax rebate to reduce the final tax liability to zero for lower-income taxpayers. Under the new regime (FY 2025-26): rebate of up to ₹60,000 if taxable income ≤ ₹12,00,000. Under the old regime: rebate of up to ₹12,500 if taxable income ≤ ₹5,00,000. Note: 87A rebate is not available on special-rate income like LTCG u/s 112A.

Example — 87A rebate (new regime)
Gross salary ₹13,50,000
Less: standard deduction – ₹75,000
Taxable income ₹12,75,000
Tax on ₹12,75,000 (slab calc) ₹67,500
87A rebate (income > ₹12L — NOT eligible) ₹0
Add: 4% cess ₹2,700
Total tax payable ₹70,200

The rebate threshold is ₹12,00,000 taxable income. At ₹12.75L taxable, no rebate applies.

 

Q6  What deductions are available under section 80C?                                               Deductions 

Section 80C allows deduction up to ₹1,50,000 per year for investments and payments such as: Life insurance premium, PPF contribution, EPF employee contribution, ELSS mutual funds, NSC, 5-year FD, tuition fees for children, home loan principal repayment, Sukanya Samriddhi Yojana. This deduction is only available under the old regime.

Example — 80C basket for Sunita
LIC premium ₹30,000
PPF contribution ₹60,000
ELSS investment ₹40,000
Children’s tuition fees ₹30,000
Total 80C investments ₹1,60,000
Maximum deductible u/s 80C ₹1,50,000
Tax saving @ 20% slab ₹30,000

Even though Sunita invested ₹1,60,000, only ₹1,50,000 is allowed as deduction — the cap is absolute.

 

Q7  How is HRA (house rent allowance) calculated?   Deductions

HRA exemption u/s 10(13A) is the minimum of: (A) Actual HRA received from employer; (B) Rent paid − 10% of Basic salary; (C) 50% of Basic salary if metro city (Delhi, Mumbai, Chennai, Kolkata), else 40%. The taxable HRA = HRA received − exempt HRA. This deduction is not available under the new regime.

Example — HRA for Karan (Delhi, non-metro rules apply for illustration)
Basic salary (monthly × 12) ₹6,00,000
HRA received ₹2,40,000
Rent paid ₹2,40,000
A) Actual HRA ₹2,40,000
B) Rent − 10% of basic (₹2,40,000 − ₹60,000) ₹1,80,000
C) 50% of basic (metro) ₹3,00,000
HRA exempt (minimum of A, B, C) ₹1,80,000
Taxable HRA ₹60,000

Always pick the minimum of all three — that is the exempt amount.

 

Q8  What is the standard deduction and who gets it?                                         Deductions

Standard deduction is a flat deduction from salary/pension income with no proof required. It replaced the earlier transport allowance + medical reimbursement benefits. For FY 2025-26: ₹75,000 under the new regime and ₹50,000 under the old regime. Available to all salaried employees and pensioners.

Example — standard deduction impact
Gross salary ₹10,00,000
Standard deduction (new regime) – ₹75,000
Net salary income ₹9,25,000
Tax saving @ 10% slab ₹7,500

The standard deduction is automatic — no bills or receipts needed. It is deducted from salary before calculating taxable income.

 

Q9  What is section 80D — health insurance deduction?                                         Deductions

Section 80D allows deduction for health insurance premiums paid for self, spouse, dependent children, and parents. Limits: ₹25,000 for self/family (₹50,000 if any member is senior citizen); ₹25,000 for parents (₹50,000 if parents are senior citizens). Maximum possible deduction: ₹1,00,000. Preventive health check-up up to ₹5,000 included within the above limits. Available only under the old regime.

Example — 80D for Deepak (parents are senior citizens)
Premium for self + spouse + kids ₹22,000
Premium for senior citizen parents ₹48,000
Preventive health check-up (self) ₹5,000
80D deduction — self/family (max ₹25,000) ₹25,000
80D deduction — parents (max ₹50,000) ₹48,000
Total 80D deduction ₹73,000

Preventive health check-up of ₹5,000 is subsumed within the ₹25,000 limit, not in addition to it.

 

Q10  What is the difference between the old and new tax regime?   Regimes

The new regime (default since FY 2023-24) offers lower slab rates with very few deductions (only standard deduction of ₹75,000 and NPS employer contribution u/s 80CCD(2)). The old regime has higher slab rates but allows ~70 deductions including 80C, HRA, 80D, home loan interest, etc. Taxpayers should compare both and choose whichever results in lower tax. The choice can be changed every year for salaried individuals.

Example — regime comparison for Nisha (₹12L salary, 80C ₹1.5L, HRA ₹1L)
— Old regime taxable income ₹9,00,000
Old regime tax + cess ₹87,880
— New regime taxable income (after std ded.) ₹11,25,000
New regime tax + cess ₹57,200
Savings under new regime ₹30,680

Even with 80C + HRA, the new regime is better here. Always compute both before deciding.

 

Q11  What are the new regime slab rates for FY 2025-26?                                        Regimes

The new regime slabs for FY 2025-26 are: ₹0–4,00,000 @ 0%; ₹4,00,001–8,00,000 @ 5%; ₹8,00,001–12,00,000 @ 10%; ₹12,00,001–16,00,000 @ 15%; ₹16,00,001–20,00,000 @ 20%; ₹20,00,001–24,00,000 @ 25%; Above ₹24,00,000 @ 30%. A rebate u/s 87A (up to ₹60,000) makes effective tax zero for taxable income up to ₹12,00,000.

Example — slab-wise tax on ₹18L taxable income (new regime)
₹0–₹4L @ 0% ₹0
₹4L–₹8L @ 5% ₹20,000
₹8L–₹12L @ 10% ₹40,000
₹12L–₹16L @ 15% ₹60,000
₹16L–₹18L @ 20% ₹40,000
Tax before cess ₹1,60,000
Add: 4% cess ₹6,400
Total tax ₹1,66,400

Tax is calculated slab-by-slab on each band of income, not on the total at the highest rate.

 

Q12  How is income from house property computed?                                            Special cases

Annual Value (AV) of let-out property = Actual rent received or Expected rent (whichever is higher). Deductions allowed: 30% standard deduction (flat, no proof), and interest on housing loan (no limit for let-out property). For self-occupied property, AV = nil; only interest on home loan is deductible, capped at ₹2,00,000 under old regime.

Example — let-out property income
Actual annual rent ₹2,40,000
Municipal taxes paid ₹12,000
Net Annual Value (NAV) ₹2,28,000
Less: 30% standard deduction – ₹68,400
Less: home loan interest – ₹1,20,000
Income from house property ₹39,600

If interest > NAV after standard deduction, a loss arises which can be set off against salary up to ₹2,00,000.

 

Q13  How are capital gains taxed?                                                                             Special cases

Capital gains depend on holding period. Short-Term Capital Gains (STCG): listed equity/equity MF held < 12 months — taxed @ 20% u/s 111A (revised from 15%, effective July 23, 2024). Other assets held < 24/36 months — taxed at slab rates. Long-Term Capital Gains (LTCG): listed equity held > 12 months — gains above ₹1,25,000 taxed @ 12.5% u/s 112A (no indexation). Other assets — 12.5% without indexation or slab rate with indexation (grandfathered).

Example — LTCG on equity shares
Purchase price (before Jan 31, 2018) ₹3,00,000
Fair Market Value on Jan 31, 2018 ₹4,50,000
Sale price (FY 2025-26) ₹8,00,000
Cost for LTCG (higher of purchase or FMV) ₹4,50,000
LTCG ₹3,50,000
Exempt LTCG (₹1,25,000 threshold) – ₹1,25,000
Taxable LTCG ₹2,25,000
Tax @ 12.5% ₹28,125

The grandfathering provision (FMV on Jan 31, 2018) applies to equity assets acquired before February 1, 2018.

 

Q14  What is surcharge and marginal relief?                                                            Advanced

Surcharge is an additional levy on income tax when taxable income exceeds ₹50 lakh. Rates: 10% for ₹50L–₹1Cr; 15% for ₹1Cr–₹2Cr; 25% for ₹2Cr–₹5Cr; 37% above ₹5Cr (capped at 25% for new regime). Marginal relief ensures the net tax increase does not exceed the marginal income increase beyond the surcharge threshold.

Example — surcharge on ₹55L taxable income
Taxable income ₹55,00,000
Base income tax (slab calc) ₹14,22,500
Surcharge @ 10% ₹1,42,250
Tax + surcharge ₹15,64,750
4% cess on above ₹62,590
Total tax payable ₹16,27,340
Effective tax rate ~29.6%

Without marginal relief, a rupee more of income can sometimes increase tax by more than ₹1. Marginal relief prevents this.

 

Q15  What is advance tax and who must pay it?           Advanced

Advance tax is income tax paid in instalments during the financial year itself, rather than at year-end. It is required if estimated tax liability for the year exceeds ₹10,000. Due dates: 15% by June 15; 45% by September 15; 75% by December 15; 100% by March 15. Non-payment attracts interest u/s 234B and 234C. Salaried employees with TDS covering all liability are generally exempt from advance tax.

Example — advance tax schedule for Vikram (tax liability ₹80,000)
By June 15 (15%) ₹12,000
By Sep 15 (45% cumulative) ₹24,000
By Dec 15 (75% cumulative) ₹24,000
By Mar 15 (100%) ₹20,000
Total advance tax paid ₹80,000

Interest u/s 234C is charged at 1% per month if any instalment is short. u/s 234B applies if total advance tax < 90% of assessed tax.
