Capital Cost Allowance (CCA) Guide for Canadian Businesses 2025

When your business purchases assets that will last more than one year — computers, vehicles, machinery, furniture, or buildings — you generally can't deduct the full cost in the year of purchase. Instead, the CRA requires you to depreciate these assets over time using the Capital Cost Allowance (CCA) system. Understanding CCA helps you plan major purchases and optimize your tax deductions strategically.

What Is Capital Cost Allowance?

CCA is Canada's tax depreciation system. Each depreciable business asset belongs to a specific CCA class, and each class has a prescribed depreciation rate. Each year you can deduct up to the maximum CCA for assets in each class — reducing your taxable income. CCA is optional: you can claim less than the maximum (or nothing) in years when you don't need the deduction, and the remainder carries forward indefinitely.

Common CCA Classes and Rates

Class	Assets Included	Rate	Method
Class 1	Most buildings acquired after 1987	4%	Declining balance
Class 8	Furniture, equipment, tools over $500, photocopiers, display fixtures	20%	Declining balance
Class 10	General-purpose vehicles, trucks, tractors	30%	Declining balance
Class 10.1	Passenger vehicles costing over $37,000 (2025)	30%	Declining balance
Class 12	Small tools under $500, computer software, cutlery, medical instruments	100%	Declining balance
Class 13	Leasehold improvements	Straight-line over lease term	Straight-line
Class 14	Patents, franchises, limited-life intangibles	Straight-line over useful life	Straight-line
Class 14.1	Goodwill, customer lists, unlimited-life intangibles (post-2016)	5%	Declining balance
Class 16	Taxis, rental cars, coin-operated video games	40%	Declining balance
Class 45	Computer equipment acquired after March 22, 2004	45%	Declining balance
Class 50	General-purpose computers and systems software	55%	Declining balance
Class 53	Eligible manufacturing and processing equipment	50%	Declining balance
Class 54	Zero-emission passenger vehicles	100%	Declining balance
Class 55	Zero-emission vehicles (non-passenger)	100%	Declining balance

The Half-Year Rule

In the year you acquire a depreciable asset, you can only claim half the normal CCA rate. This applies to most classes. The logic: the CRA assumes assets are typically acquired mid-year, so only half a year's depreciation is allowed in year 1.

Example: You buy $100 of office furniture (Class 8, 20% rate) in 2025. Year 1 CCA = $100 × 20% × 50% = $1,000. In Year 2, the UCC is $9,000 and you can claim $9,000 × 20% = $1,800.

Undepreciated Capital Cost (UCC)

The UCC is the remaining balance of an asset class after CCA has been claimed. Each year's CCA is calculated on the UCC (opening balance + additions − disposals). You can track this on Schedule 8 of your T2 or on your T1 Schedule if you're self-employed.

Immediate Expensing for CCPCs

Since 2022, eligible Canadian-Controlled Private Corporations can immediately expense up to $1.5 million per year of eligible depreciable property acquired after April 18, 2021. Instead of claiming CCA over multiple years, you deduct the full cost in the year of purchase.

Eligible Property for Immediate Expensing

Most depreciable property is eligible, except:

Class 1 (buildings)
Class 14.1 (goodwill and intangibles)
Property acquired from a non-arm's length person
Property that previously belonged to the corporation or related party

Planning Opportunity: If you're planning major equipment or technology purchases, timing them to maximize the immediate expensing limit can eliminate significant taxable income. The $1.5M limit is shared among associated corporations.

Recaptured CCA and Terminal Loss

When you sell an asset in a CCA class:

Recaptured CCA: If the proceeds exceed the UCC of the class, the excess is "recaptured" and included in your business income. This happens when the UCC is lower than what you sell the asset for.
Terminal loss: If you dispose of all assets in a class and the UCC is greater than zero, the remaining balance is a terminal loss — fully deductible as a business loss.
Capital gain: If proceeds exceed the original cost of the asset, a capital gain results (50% inclusion rate for capital gains).

CCA and the T2/T1 Return

Corporations report CCA on Schedule 8 (Capital Cost Allowance) of the T2. Sole proprietors use Form T2125, Part B. You must list each asset class, opening UCC, additions, disposals, and CCA claimed.

CCA Strategy: Should You Always Claim the Maximum?

CCA is discretionary — you're not required to claim the maximum. Consider claiming less CCA when:

Your business already has little or no taxable income (the deduction won't help)
You expect higher income in future years and want to save the deduction
You're planning to sell the business and want to maintain a higher UCC (reducing recapture)
