Depreciation is a deduction permitted under the Income Tax Act, accounting for the decrease in the actual value of a tangible or intangible asset used by a taxpayer.
Table of Contents
It is mandatory to calculate depreciation on assets used or acquired for business or professional purposes, as per the Income Tax Act of 1962, which specifies varying depreciation rates for different asset categories.
Depreciation refers to the allocation of an asset's cost over its useful life. It is a mandatory deduction recorded in the profit and loss statements of an entity using depreciable assets.
The Income Tax Act permits depreciation to be calculated either through the Straight-line method or the Written Down Value (WDV) method. While the WDV method is commonly applied, entities engaged in power generation or both generation and distribution have the option to use the Straight-line method. Additionally, under certain conditions, the Act provides for an extra deduction of depreciation in the year of asset purchase.
The Income Tax Act 1962, has made it mandatory to calculate depreciation. Following are the depreciation rates for different classes of assets.

Depreciation is calculated on the Written Down Value (WDV) of a block of assets. A block of assets is a group of assets categorised within a class, which includes:
The classification of a block of assets is based on factors such as the asset's nature, lifespan, and similar usage. The depreciation rate within each asset class is used to further classify the assets. Each class of assets with the same depreciation rate forms a block.
Under the Income Tax Act, individual assets lose their separate identity, as depreciation is calculated collectively on the block of assets rather than on individual items.
According to Section 32(1) of the Income Tax Act, depreciation must be calculated at the prescribed rate on the Written Down Value (WDV) of the asset, which is determined based on the actual cost of the asset. To accurately compute depreciation, it is essential to understand the concepts of ‘WDV’ and ‘Actual Cost'.
Under the Income Tax Act:
Depreciation is a deduction permitted under the Income Tax Act that accounts for the decrease in the actual value of a tangible or intangible asset used by a taxpayer.
Depreciation can be calculated using either the Straight-line Method (SLM) or the Written Down Value (WDV) Method. The WDV method is commonly used, but entities involved in power generation and distribution can opt for the SLM method.
Depreciation is calculated on a "Block of Assets," which is a group of assets within a similar class, such as buildings, machinery, or intangible assets. The depreciation is applied to the entire block, not individual assets.
Depreciation can be claimed by the owner or co-owners of the asset. If an asset is used for both business and personal purposes, depreciation will be proportional to the business use.
The taxpayer must own the asset (wholly or partially) and use it for business or professional purposes. Depreciation cannot be claimed on goodwill or land. From Assessment Year 2002-03, claiming depreciation is mandatory.
The primary difference is in the calculation method. The Income Tax Act uses either the WDV method or the SLM method for power generation companies, while the Companies Act provides different depreciation rates and methods.
WDV refers to the actual cost of an asset minus the depreciation already allowed. For assets acquired in the previous year, the WDV equals the actual cost, while for older assets, it is the original cost, less the accumulated depreciation.
Yes, in finance lease transactions, the lessee is required to capitalise the asset in its books and can claim depreciation as the effective owner of the asset under Accounting Standard AS-19.
In the event of an amalgamation or demerger, the total depreciation allowance is apportioned between the companies involved based on the period the assets were used by each company.
Yes, under certain conditions, the Income Tax Act allows for an additional depreciation deduction in the year an asset is purchased. This helps in reducing the taxable income for that year.
