There are two methods of calculating depreciation, i.e. Written down Value (WDV) method and Straight Line Method (SLM). Income tax allows WDV method of depreciation. Also, income tax allows to deduct additional depreciation as explained below:

Additional Depreciation

In case of any new machinery or plant (excluding ships and aircraft) acquired and installed after March 31, 2005 by an assessee who is engaged in the business of manufacture or production of any article or thing – additional depreciation under Income Tax Act of 20% of actual cost shall be allowed.

From A.Y. 2013-14 the same is also allowed to assessee engaged in the business of generation or generation and distribution of power, where the depreciation is provided on WDV method as per Appendix I.

From assessment year 2017-18 the same is also allowed to the assessee engaged in the business of transmission of power.

Where the asset is used for less than 180 days then 50% depreciation i.e, 1/2 of 20% (i.e. 10%) is available (Balance 50% of Additional Depreciation can be claimed in next year)

No such additional deduction will be allowed in respect of machinery or plant—

  • Used by any other person in India or outside India before its installation.
  • Installed in any office premises or any residential accommodation,
  • including a guest house.
  • Any office appliances or road transport vehicles.

  • in the State of Andhra Pradesh; or
  • in the State of Bihar; or
  • in the State of Telangana; or
  • in the State of West Bengal

Such Assessee acquires and installs new machinery, other than ships and aircraft, then the additional depreciation is available to such undertaking or enterprise for the period from 01.04.2015 to 31.03.2020 at 35% instead of 20%.
