What is CCA (Capital Cost Allowance)?
Capital Cost Allowance is Canada's tax depreciation system for business assets. Instead of deducting the full cost of a depreciable asset in the year of purchase, businesses claim CCA at prescribed rates over time. Different asset classes attract different CCA rates: Class 10 (30% declining balance for most vehicles), Class 8 (20% for office equipment), Class 14.1 (5% for goodwill and eligible capital property).
Current Rate (Corporate fiscal year or personal tax year)
Varies by class: Class 10 (30%), Class 8 (20%), Class 14.1 (5%), Class 10.1 (30% with CAD 36,000 cost cap). Half-year rule reduces first-year deduction to 50% of normal CCA.
Example
A consultant purchases a CAD 3,000 laptop (Class 10). Normally the first-year CCA would be 30% x CAD 3,000 = CAD 900, but the half-year rule reduces this to CAD 450 in year 1. Year 2 CCA: 30% x (CAD 3,000 minus CAD 450) = CAD 765. The undepreciated capital cost (UCC) carries forward each year.
How CCA (Capital Cost Allowance) works in Canada
Capital Cost Allowance (CCA) is the mechanism by which Canadian businesses recover the cost of capital assets for tax purposes. CCA differs from book depreciation: CCA classes and rates are prescribed by the Income Tax Regulations, and businesses may claim less than the maximum CCA in any year (CCA is discretionary). This discretion allows businesses to defer CCA claims to years when they have taxable income, maximising the tax value of the deductions.
**The undepreciated capital cost (UCC) pool**
CCA is calculated on a pool basis for each class. All assets in the same class are pooled together. When an asset is added to the pool, its cost increases the UCC. When an asset is sold, the lesser of proceeds of disposition and original cost is deducted from the pool. CCA for the year is then a percentage of the UCC at the end of the year (subject to the half-year rule). If proceeds of disposition exceed the UCC of a class, the excess is recaptured and included in income. If the UCC of a class becomes negative after all assets are removed, a terminal loss is deducted.
**The half-year rule**
In the year an asset is acquired, the maximum CCA claimable is limited to 50% of the normal CCA rate. This rule applies regardless of when in the year the asset was acquired. The half-year rule is applied to the net additions to each class (additions minus disposals for the year) before calculating CCA.
**Accelerated Investment Incentive (AII)**
The Accelerated Investment Incentive was introduced in 2018 and provided enhanced first-year CCA deductions for eligible property acquired after 20 November 2018. Under AII, the half-year rule was suspended and CCA was calculated on 1.5 times the normal rate in the year of acquisition. AII was phased out after 2023 for most property. For 2024 and later years, the normal half-year rule applies.
**Immediate expensing for CCPCs**
CCPCs could claim up to CAD 1.5 million in immediate expensing (100% first-year CCA) on eligible designated immediate expensing property (DIEP) acquired after 18 April 2021. The immediate expensing incentive for CCPCs was set to phase out after 2023 (full elimination after 2024). Businesses should verify current status, as tax rules in this area change frequently.
**Passenger vehicle limits**
Class 10.1 applies to passenger vehicles costing more than CAD 36,000 (the prescribed amount for 2024, indexed annually). The CCA rate is 30%, but the deduction is capped at the prescribed ceiling, not the actual cost. Each Class 10.1 vehicle is its own separate class with its own UCC pool. This prevents high-cost luxury vehicles from generating excessive CCA deductions.
