Section 137-143 capital gains exemption — Detailed Analysis
Section 137-143 — Core Provisions
What it provides: Section 137-143 establishes the legal framework for Section 137-143 capital gains exemption — covering the charging provision (what is taxable), computation methodology (how to calculate), applicable rates, exemptions/deductions available, and compliance requirements. It must be read with the applicable Income Tax Rules, 2026 and CBDT circulars for complete understanding.
Key aspects: (a) Scope — who is covered and what income is included, (b) Computation — step-by-step calculation methodology with specific inclusions and exclusions, (c) Rates — applicable tax rates including surcharge and cess, (d) Exemptions — conditions for claiming any available exemptions, (e) Filing — return forms, due dates, and documentation requirements.
Individual taxpayers: Must choose between old regime (with deductions) and new regime (lower rates, fewer deductions). New regime is default from AY 2024-25 under the 1961 Act. The 2025 Act continues this default position.
Business taxpayers: Must maintain books of account (Section 44AA/corresponding new section), get tax audit if turnover exceeds threshold (Section 44AB equivalent), file return by October 31, and pay advance tax in quarterly installments.
Compliance Framework
Return filing: ITR in prescribed form by due date (July 31 for individuals without audit, October 31 for audit cases, November 30 for transfer pricing). Belated return till December 31 with Rs. 5,000 penalty. Updated return (ITR-U) within 24 months with 25%/50% additional tax.
Advance tax: If tax liability exceeds Rs. 10,000 — pay in 4 installments: 15% by June 15, 45% by September 15, 75% by December 15, 100% by March 15. Interest under 234B (short payment) and 234C (deferment) at 1% per month.
TDS/TCS: Deductors must deduct at prescribed rates, deposit by 7th of next month (March: April 30), file quarterly returns (24Q/26Q/27Q/27EQ), and issue certificates (Form 16/16A). Late deposit: interest 1.5% per month from deduction to deposit date.
Practical Examples — Section 137-143 capital gains exemption
Example 1 — Salaried Individual
Scenario: Rajesh, salaried employee in Delhi, gross salary Rs. 12 lakh, HRA received Rs. 2.4 lakh, rent paid Rs. 3 lakh, 80C investments Rs. 1.5 lakh, 80D medical insurance Rs. 25,000.
Under Old Regime: Gross Salary Rs. 12L − Standard Deduction Rs. 75K − HRA Exemption (calculated) − 80C Rs. 1.5L − 80D Rs. 25K = Taxable income approximately Rs. 8-9L. Tax at slab rates + 4% cess.
Under New Regime: Gross Salary Rs. 12L − Standard Deduction Rs. 75K = Rs. 11.25L. Tax at new regime slab rates. Rebate under 87A if income ≤ Rs. 12L effectively makes tax = NIL for income up to Rs. 12.75L (with standard deduction).
Example 2 — Business Person (Presumptive)
Scenario: Amit, retail trader, turnover Rs. 1.5 crore, all digital receipts.
Under 44AD: Deemed profit = 6% of Rs. 1.5 Cr = Rs. 9 lakh (digital receipts rate). No books required, no tax audit. File ITR-4 by July 31. Pay advance tax in single installment by March 15.
Example 3 — Capital Gains on Property
Scenario: Priya sells residential house for Rs. 80 lakh (held 5 years). Purchased for Rs. 40 lakh. Stamp duty value Rs. 85 lakh.
Computation: Sale consideration = higher of actual or stamp duty value = Rs. 85L. Indexed cost (using CII) approximately Rs. 52L. LTCG = Rs. 33L. Tax at 12.5% = Rs. 4.125L + cess. Can claim Section 54 exemption if reinvests in residential house within 2 years or constructs within 3 years.

Judicial Interpretations
Supreme Court: Tax provisions are to be interpreted strictly — neither extended nor restricted beyond their plain meaning. Exemptions must be strictly construed. DTAA provisions override domestic law to the extent beneficial to the assessee (beneficial interpretation).
High Courts / ITAT: Burden of proof for claiming deductions/exemptions is on the assessee. AO cannot make additions without evidence. Principles of natural justice must be followed in assessment proceedings. Faceless assessment orders without proper hearing are quashed.
