Common capital cost allowance (CCA) classes and rates

The Capital cost allowance (CCA) is a tax deduction that Canadian tax laws allow a business to claim for the loss in value of capital assets due to wear and tear or obsolescence.

Depreciable assets are usually grouped into classes. The class system is used to prescribe a declining balance rate of depreciation. The total balance of the class (undepreciated capital cost (UCC) balance) is depreciated at the same percentage rate prescribed for that class.

Here are the commonly used classes and their CCA rates. (a CCA calculation example)
