Depreciation Rates for FY 2025-26

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.

Updated On - 16 Sep 2025

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. 

What is Depreciation?

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.

Formula for Depreciation Calculation

  1. Straight-line Method Rate of Depreciation (SLM)= (Original Cost−Residual Value/Useful Life) × 100
  2. Depreciation Amount= Original Cost × Rate of Depreciation (SLM)

Concept of Blocking 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:

  1. Tangible Assets: Tangible assets such as buildings, machinery, plants, or furniture.
  1. Intangible Assets: Intangible assets like know-how, patents, copyrights, trademarks, licenses, franchises, or other business or commercial rights of a similar nature. 

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.

What is Written Down Value (WDV) of Assets?

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:

  1. If the asset is acquired during the previous year, its actual cost is considered the WDV.
  1. If the asset was acquired in an earlier year, the WDV is the actual cost of the asset minus the depreciation already allowed under the Act.

Conditions for Claiming Depreciation

  1. The asset must be wholly or partially owned by the taxpayer.
  1. The asset must be used for the taxpayer's business or profession. If the asset is used for both business and personal purposes, depreciation will be proportionate to its business use. The Income Tax Officer can determine the appropriate depreciation under Section 38 of the Income Tax Act.
  1. Co-owners are eligible to claim depreciation based on the portion of the asset they own.
  1. Depreciation cannot be claimed on Goodwill or land.
  1. From Assessment Year 2002-03 onwards, claiming depreciation is mandatory and will be allowed or deemed allowed, regardless of whether the taxpayer claims it in the profit & loss account. The Written Down Value (WDV) will be reduced by the depreciation amount accordingly.
  1. If the presumptive taxation scheme is opted for, the deemed profit is considered to already reflect the impact of depreciation.
  1. Depreciation under the Income Tax Act follows specific rates, which differ from those under the Companies Act, 1956. Therefore, only the rates prescribed by the Income Tax Act are allowed, regardless of the rates used in the taxpayer’s books of accounts.

FAQs on Depreciation under the Income Tax Act

  • What is depreciation 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.

  • How is depreciation calculated under the Income Tax Act?

    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.

  • What is the concept of 'Block of Assets'?

    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.

  • Who is eligible to claim depreciation on 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.

  • What conditions must be met to claim depreciation?

    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.

  • What is the difference between depreciation under the Income Tax Act and the Companies Act?

    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.

  • What is a Written Down Value (WDV)?

    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.

  • Can depreciation be claimed on leased assets?

    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.

  • What happens to depreciation in the case of amalgamation or demerger?

    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.

  • Can additional depreciation be claimed in the year of purchase?

    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.
