accelerated depreciation

The allocation of the cost of a plant asset to expense in an accelerated manner. This means that the amount of depreciation in the earlier years of an asset's life is greater than the straight-line amount, but will be less in the later years. In total the amount of depreciation over the life of the asset will be the same as straight-line depreciation. The difference between accelerated and straight-line is the timing of the depreciation. For profitable companies, the use of accelerated depreciation on the income tax return will mean smaller cash payments for income taxes in the earlier years and higher cash payments for income taxes in later years.
