Business -> Capital cost allowance (CCA) rates

Capital Cost Allowance

Income Tax Act s. 20(1)(a), Regulations Parts XI, XVII

Capital cost allowance (CCA) is the depreciation that is allowed to be expensed for tax purposes for fixed assets, except land.  Different types of assets are allocated to different CCA classes, and each class has its own rate for capital cost allowance.  For instance, most automobiles would be class 10, which is expensed at 30% per year on a declining balance basis.  In most cases, the CCA allowed in the year an asset is purchased is only 50% of the normal amount - this is the "half-year" rule.  Thus, the class 10 CCA would be 15% in the first year.  See below for more information on the half-year rule.

Capital Cost Allowance Classes and Rates

There are many classes of capital cost allowance (CCA).  Lists of many of the classes, as well as information on calculating capital cost allowance, can be found in the following Canada Revenue Agency guides and bulletin:

T2 Corporation Income Tax Guide (T4012), other Guides, T2 return and schedules - for information on CCA rates, search for the phrase "CCA rates and classes" in T4012.  To search any web page or pdf document, do ctrl-f to bring up the search box.

T4002 Self-employed Business, Professional, Commission, Farming and Fishing Income Guide for unincorporated businesses has CCA rates (Chapter 4) as well as a table which explains how to determine if a cost is an expense or should be capitalized (Chapter 3 - current or capital expenses?).

Rental Income Tax Guide (T4036) lists some of the classes which are more likely to be used by someone with a rental property.

Capital Cost Allowance Half-Year Rule

Income Tax Regulations s. 1100(2) to (2.4)

For most capital additions in the year, you can only claim CCA on one-half of your net additions to the CCA class in the year.  The net additions amount is the cost of additions in the year less the lower of cost or proceeds of disposition for assets disposed of during the year.

Some additions are not subject to the half-year rule.  These include additions in classes 13, 14, 23, 24, 27, 29, 34, and 52, as well as most of the additions to Class 12.

Class 12, which has a CCA rate of 100%, includes a variety of assets, including small tools, kitchen utensils, and medical or dental instruments costing less than $500 (less than $200 for purchases before May 3, 2006), as well as linens, uniforms, computer software and other items.  The half-year rule does not apply to most items in Class 12, allowing 100% write-off in the year of acquisition.  The only items in Class 12 to which the half-year rule does apply are:

    - a die, jig, pattern, mould or last
    - the cutting or shaping part in a machine
    - a motion picture film or video tape that is a television commercial message
    - a certified feature film or certified production
    - class 12(o), which is computer software, but this does not include systems software, which is included in class 10

See paragraph 1.38 Half-year rule in the CRA Income Tax Folio S3-F4-C1, General Discussion of Capital Cost Allowance, for more detail on this topic.

Capital Cost Allowance  - Short Fiscal Year

Income Tax Regulations s. 1100(3) Taxation Years Less Than 12 Months

When the fiscal year is shorter than 365 days, generally the capital cost allowance must be prorated.  For instance, if the fiscal year is 200 days, first calculate the maximum CCA claim for a full year, then multiply by 200 and divide by 365.  This must be done for all property except classes of property that are excluded by Regulation 1100(3).  The property classes that are not prorated for a short fiscal year include:

    - Class 14 assets
    - Class 15 assets
    - timber limits and cutting rights
    - industrial mineral mines
    - certified productions
    - Canadian film or video productions, and
    - certain mining equipment in classes 28 and 41.

Other articles relating to CCA:


Terminal Loss

Property Rental

Tax Tip:  If you are planning to buy an asset and yearend is approaching, buy it before yearend so that you will get the full CCA write-off sooner.  Note that the asset must be available for use in order to claim CCA.
