Overview
This article provides a detailed explanation of How to Calculate Cost of Improvement for Capital Gains under the Income Tax Act, 1961, Income Tax Act, 2025, and applicable Rules. All amendments up to Finance Act 2025 and CBDT Circulars up to March 2026 are incorporated.
Relevant provisions: Section 48/55.
Legal Framework
Section 48/55 governs cost of improvement. Under the Income Tax Act, 1961, these provisions establish the scope, computation method, compliance requirements, and consequences of non-compliance. The new Income Tax Act, 2025 simplifies the language and replaces Previous Year/Assessment Year with the Tax Year concept, while largely maintaining the substantive law.

Detailed Explanation with Examples
Example 1: A taxpayer in Faridabad earning Rs. 15 lakh salary under new regime: Taxable = 15,00,000 - 75,000 (SD) = 14,25,000. Tax on graduated slabs = Rs. 1,48,750 + 4% cess = Rs. 1,54,700. Compare with old regime after claiming 80C (1.5L), 80D (25K), HRA (2.4L) = lower taxable but higher slab rates.
Example 2: A business owner with Rs. 2 crore turnover (95% digital) opts for 44AD: 6% of 1.9 crore + 8% of 10 lakh = Rs. 11,40,000 + Rs. 80,000 = Rs. 12,20,000 presumptive income. No need to maintain books or get tax audit.
