Capital Cost Allowance (CCA) Explained: A Guide to CRA Depreciation Classes

When you buy equipment, furniture, or a vehicle for your business, you cannot deduct the full cost in the year you bought it. Instead, the CRA requires you to spread the deduction over several years through a system called Capital Cost Allowance (CCA). This is the Canadian equivalent of depreciation.

Understanding CCA can save you thousands of dollars in taxes, but the rules are specific. This guide covers the classes you are most likely to encounter, how to calculate your deduction, and what happens when you dispose of an asset.

What Is Capital Cost Allowance?

CCA is the tax deduction the CRA allows you to claim each year for the gradual decline in value of your capital assets. A capital asset is anything you purchase for long-term business use, typically costing $500 or more. Think computers, vehicles, furniture, and buildings.

Instead of expensing the full purchase price in year one, you assign the asset to a CCA class. Each class has a prescribed rate that determines how much you can deduct annually.

CCA is optional. You can claim less than the maximum in any year, or skip it entirely. This is useful if your income is low and you want to save the deduction for a higher-income year.

Common CCA Classes

The Income Tax Regulations, Schedule II defines dozens of CCA classes. Here are the ones most relevant to freelancers and small business owners:

Class	Rate	Type	Examples
1	4%	Buildings	Rental properties, office buildings acquired after 1987
8	20%	Miscellaneous tangible property	Furniture, appliances, tools over $500, photocopiers, fax machines
10	30%	Vehicles and equipment	Motor vehicles (not passenger vehicles over the cost limit)
10.1	30%	Luxury passenger vehicles	Passenger vehicles costing more than the prescribed limit ($37,000 before tax for 2024)
12	100%	Small tools and software	Tools under $500, computer software (not systems software), tableware, kitchen utensils
50	55%	Computer equipment	General-purpose electronic data processing equipment (computers, laptops, tablets) acquired after January 27, 2009

Class 10 vs Class 10.1

This distinction trips up many business owners. If your passenger vehicle costs at or below the CRA's prescribed limit (check the CRA's annual automobile deduction limits), it goes in Class 10 with your other vehicles. If it costs above the limit, it goes in Class 10.1.

The key difference: each Class 10.1 vehicle gets its own separate class. You cannot pool it with other vehicles. And when you sell a Class 10.1 vehicle, there is no recapture and no terminal loss, which simplifies the disposition but means you lose some flexibility.

Class 12: The 100% Write-Off

Class 12 is powerful because it lets you deduct the full cost of qualifying items. Computer software (applications, not operating systems), tools under $500, and certain other small items all qualify. Subject to the half-year rule, you can typically deduct 50% in year one and the remaining 50% in year two.

The Half-Year Rule

In the year you acquire an asset, the CRA only lets you claim CCA on half the net addition to the class. This is the half-year rule, and it applies to most CCA classes.

Example: You buy a $2,000 laptop in 2025 (Class 50, 55% rate).

• Year 1: CCA base = $2,000 x 50% (half-year rule) = $1,000. CCA = $1,000 x 55% = $550
• Year 2: Undepreciated capital cost (UCC) = $2,000 - $550 = $1,450. CCA = $1,450 x 55% = $797.50
• Year 3: UCC = $1,450 - $797.50 = $652.50. CCA = $652.50 x 55% = $358.88

And so on until the balance is negligible.

The half-year rule does not apply in the year you dispose of an asset.

How to Calculate CCA: Step by Step

Here is the general formula for the declining-balance method used by most CCA classes:

1. Start with the opening UCC for the class (the undepreciated capital cost carried forward from the prior year).
2. Add the cost of any new assets acquired during the year.
3. Subtract the proceeds of disposition for any assets sold during the year (limited to the original cost of the asset).
4. Apply the half-year rule to net additions (acquisitions minus dispositions, if positive).
5. Multiply the adjusted UCC by the class rate. That is your CCA deduction for the year.
6. Subtract the CCA claimed from the UCC. The remainder carries forward to next year.

A Practical Example

You are a freelance consultant. At the start of 2025, your Class 8 (20% rate) has an opening UCC of $3,000 from prior furniture purchases. During the year, you buy a $1,500 standing desk.

Step	Amount
Opening UCC	$3,000
Add: new desk	$1,500
Half-year rule on net addition: $1,500 x 50%	-$750
Adjusted UCC for CCA calculation	$3,750
CCA at 20%	$750
Closing UCC: ($3,000 + $1,500) - $750	$3,750

You claim $750 as a CCA deduction on your T2125. The $3,750 closing UCC carries forward to 2026.

Accelerated Investment Incentive (ACII)

For certain property acquired after November 20, 2018, the federal government introduced an Accelerated Investment Incentive that enhanced the first-year CCA deduction. Instead of the half-year rule allowing CCA on 50% of the net addition, the ACII applied a factor of 1.5 to the net addition in the first year, effectively tripling the normal first-year deduction.

Phase-down schedule: The ACII has been phasing down. For property that became available for use in 2024, the enhanced factor was reduced to 1.25x. For 2025, it dropped to 1.0x (equivalent to the regular half-year rule). For property acquired in 2026 and later, the standard half-year rule applies. Check the CRA's current guidance to confirm the rules for your acquisition year.

Recapture and Terminal Loss

When you sell or dispose of an asset, two things can happen to the remaining UCC in that class:

Recapture

If you sell an asset and the proceeds bring the UCC of the class below zero, the negative amount is added back to your income as recapture. This happens when you sold the asset for more than its depreciated value, meaning you claimed too much CCA over the years.

Example: Your Class 8 has a UCC of $800. You sell the only remaining asset in the class for $2,000 (but its original cost was $3,000). The UCC becomes $800 - $2,000 = -$1,200. That $1,200 is recapture and gets added to your business income.

Recapture is not a penalty. It simply corrects the over-deduction.

Terminal Loss

If you dispose of all the assets in a class and the UCC is still positive, that remaining amount is a terminal loss. You can deduct it in full in the year of disposition.

Example: Your Class 10 vehicle has a UCC of $5,000. You sell it for $2,000. The UCC becomes $5,000 - $2,000 = $3,000. Since there are no assets left in the class, the $3,000 is a terminal loss and is fully deductible.

Exception: Class 10.1 vehicles do not qualify for terminal loss or recapture. When you dispose of a Class 10.1 vehicle, the class simply goes to zero.

Tips for Managing CCA

• You do not have to claim the maximum. If your income is low this year, save your CCA room for a year when you are in a higher tax bracket.
• Keep records of every asset. Track the purchase date, cost, class, and any disposition. The CRA can ask for this at any time.
• Review class assignments carefully. Putting an asset in the wrong class can trigger reassessment.
• Consider immediate expensing rules. Canadian-controlled private corporations and unincorporated businesses may be eligible to immediately expense up to $1.5 million of certain capital property per year. Check current eligibility.
