Cost of Improvement — The Capital Gain Deduction That Requires an Engineer
The cost of improvement (CoI) deduction under Section 48 of the Income Tax Act is the capital expenditure incurred on making an addition to, or alteration in, a capital asset after its acquisition.
For immoveable property, this includes additional floors constructed after the original acquisition, room additions, structural renovations, lift installations, boundary wall construction and major landscaping. The CoI reduces the capital gain, and its quantum can be significant for properties held over multiple decades with major structural additions.
What Qualifies as Cost of Improvement
The distinction is between capital expenditure that adds to, alters or materially enhances the asset and expenditure that merely maintains the property in its existing condition.
Expenditure That Qualifies
Expenditure That Does Not Qualify
Cost of improvement incurred before 1 April 2001 is deemed nil and is not deductible under Section 55(1)(b). Only post-2001 CoI is deductible.
The Civil Engineer’s Assessment of Cost of Improvement
ENGINEERING
When invoices are missing, the physical improvement itself becomes evidence.
The primary challenge in claiming the cost of improvement deduction is often the absence of documentary evidence. Contractor invoices from 2005 or 2010 may not have been preserved; the family’s general memory of what was spent is not sufficient evidence for the Assessing Officer.
The Civil Engineer’s assessment fills this gap by assessing the physical evidence of the improvements actually made — including the additional floor’s construction quality and dimensions, materials used and structural specifications.
Measurement and assessment of the additional floor, room extension or structural addition.
Assessment of the nature and quality of construction visible in the existing improvement.
Physical assessment of materials incorporated into the improvement and their construction application.
Engineering assessment of the structural characteristics relevant to the improvement.
From Physical Improvement to a Defensible Cost Figure
Nitesh Shrivastava can assess the cost of improvement from the physical evidence of the improvements made and from the Schedule of Rates (SOR) published by the state government’s Public Works Department (PWD) for the year in which the improvement was made.
The PWD SOR provides the official cost per square metre for different types of construction in each year. Applying the relevant SOR rates to the documented improvement dimensions produces a defensible cost of improvement figure even where contractor invoices are unavailable.
This is a Government Approved Valuer’s certificate that a Civil Engineer can produce credibly by connecting the physical improvement, engineering assessment and applicable historical construction rates.
