How to calculate the deduction for capital cost allowance (CCA)

The Capital cost allowance you can claim depends on the type of property you own and the date you acquired it.

You group the depreciable property you own into CRA classes of depreciable property. For an explanation of the most common classes of property, go to Classes of depreciable property. A specific rate of CCA generally applies to each class. For a list of most classes and their rates, go to Capital cost allowance (CCA) classes.

Base your CCA claim on your fiscal period ending in the current tax year and not the calendar year.

There are a few things you should know about CCA, such as the difference between a current and capital expense, the declining balance method and the impact on the CCA of a fiscal period. For more information, go to Basic information about capital cost allowance (CCA).

To help calculate your current tax year deduction for CCA, and any recaptured CCA, as well as terminal losses, use:

You may have acquired or disposed of buildings or equipment during the fiscal period. If so, see Area B, C, D or E, whichever applies, before completing Area A on Form T2125.

If you want to claim CCA under the immediate expensing rules and you are part of an associated group of eligible persons or partnerships, fill in Area G before completing Area A on Form T2125 to calculate the immediate expensing limit allocated to your business.

Note

Even if you are not claiming a deduction for CCA for the current tax year, fill in the appropriate areas of the form to show any additions and dispositions during the year.

To calculate your CCA claim, you will need to know the meaning of:

Available for use

You can usually claim CCA on a property only when it becomes available for use.

Property other than a building usually becomes available for use on the earlier of:

A building or part of a building usually becomes available for use on the earlier of the following date:

A building or part of a building that you are constructing, renovating or altering usually becomes available for use on the earlier of:

Capital cost

This is generally your full cost of acquiring the property. The capital cost of a property is usually the total of:

Proceeds of disposition

The proceeds of disposition are the amounts you receive, or that we consider you to have received, when you dispose of your property (usually the selling price of the property). Proceeds of disposition is also defined to include, amongst other things, compensation received for property that has been destroyed, expropriated, damaged or stolen.

Special rules may apply if you dispose of a building for less than both its undepreciated capital cost and your capital cost. If this is the case, go to Disposing of a building in the year.
