Depreciation Rates

Meaning of Depreciation

Depreciation refers to the reduction in the value of a fixed asset as a result of its normal usage and wear and tear. Knowledge of depreciation is essential for writing off the asset's cost against profit over its life.

Under the Income Tax Act, depreciation is charged against income. There are varying techniques of assessing it, such as straight-line method or written down value method (WDV). The Act recognizes WDV method of depreciating asset, except for establishments involved in generation and/or distribution of power.
