Depreciation Rates Under Companies Tax Act



  1. Depreciation is the systematic allocation of the depreciable amount of an asset over its useful life. The depreciable amount of an asset is the cost of an asset or other amount substituted for cost, less its residual value. The useful life of an asset is the period over which an asset is expected to be available for use by an entity, or the number of production or similar units expected to be obtained from the asset by the entity.
  1. For the purpose of this Schedule, the term depreciation includes amortisation.
  2. Without prejudice to the foregoing provisions of paragraph 1,—

(i) In case of such class of companies, as may be prescribed and whose financial statements comply with the accounting standards prescribed for such class of companies under section 133 the useful life of an asset shall not normally be different from the useful life and the residual value shall not be different from that as indicated in Part C, provided that if such a company uses a useful life or residual value which is different from the useful life or residual value indicated therein, it shall disclose the justification for the same.

(ii) In respect of other companies the useful life of an asset shall not be longer than the useful life and the residual value shall not be higher than that prescribed in

Part C.

(iii) For intangible assets, the provisions of the Accounting Standards mentioned under sub-para (i) or (ii), as applicable, shall apply.


  1. The useful life or residual value of any specific asset, as notified for accounting purposes by a Regulatory Authority constituted under an Act of Parliament or by the Central Government shall be applied in calculating the depreciation to be provided for such asset irrespective of the requirements of this Schedule.

  1. “Factory buildings” does not include offices, godowns, staff quarters.
  2. Where, during any financial year, any addition has been made to any asset, or where any asset has been sold, discarded, demolished or destroyed, the depreciation on such assets shall be calculated on a pro rata basis from the date of such addition or, as the case may be, up to the date on which such asset has been sold, discarded, demolished or destroyed.
  1. The following information shall also be disclosed in the accounts, namely:—

(i) depreciation methods used; and

(ii) the useful lives of the assets for computing depreciation, if they are different from the life specified in the Schedule.

  1. Useful life specified in Part C of the Schedule is for whole of the asset. Where cost of a part of the asset is significant to total cost of the asset and useful life of that part is different from the useful life of the remaining asset, useful life of that significant part shall be determined separately.
  1. Depreciable amount is the cost of an asset, or other amount substituted for cost, less its residual value. Ordinarily, the residual value of an asset is often insignificant but it should generally be not more than 5% of the original cost of the asset.
  1. The useful lives of assets working on shift basis have been specified in the Schedule based on their single shift working. Except for assets in respect of which no extra shift depreciation is permitted (indicated by NESD in Part C above), if an asset is used for any time during the year for double shift, the depreciation will increase by 50% for that period and in case of the triple shift the depreciation shall be calculated on the basis of 100% for that period.
  1. From the date this Schedule comes into effect, the carrying amount of the asset as

on that date—

(a) shall be depreciated over the remaining useful life of the asset as per this


(b) after retaining the residual value, shall be recognised in the opening balance of retained earnings where the remaining useful life of an asset is nil.

  1. ‘‘Continuous process plant’’ means a plant which is required and designed to operate for twenty-four hours a day.
