As a business proprietor, you’re probably familiar with the array of tax advantages. Beyond the primary benefit of deducting expenditures from your earnings, another valuable avenue exists: claiming tax deductions for CCA depreciation. This tax advantage is called Capital Cost Allowance, abbreviated as CCA.
In 2021, Canadian businesses claimed CCA deductions of $124.8 billion. This was an increase of 10.4% from 2020.
When your business possesses depreciable assets like buildings, vehicles, or equipment, their value gradually diminishes over time – a phenomenon recognized as depreciation in accounting terms.
However, the tax code extends the opportunity also to derive a deduction based on this depreciation.
For certain assets, the tax laws in Canada do not allow you to fully deduct the purchase cost in the year of acquisition. The Income Tax Act refers to these expenditures as capital outlays and classifies them as capital assets.
What is Capital Cost Allowance (CCA) in Canada?
Capital Cost Allowance (CCA) is a tax provision designed for the depreciation of depreciable assets. When you procure an asset, such as a vehicle, building, or software, its value gradually erodes or may become outdated.
While owning such assets brings advantages, it also entails inherent ownership risks. Acknowledging this dynamic, the Canada Revenue Agency (CRA) permits you to claim CCA as a deduction in recognition of these factors.
Capital assets would include computers, automobiles, furniture, buildings, etc. Expenses incurred for capital assets differ in nature from operating expenses such as advertising, supplies and rent because capital assets are generally held and used over longer periods. An automobile, for instance, would likely be used in your business over several years.
For this reason, the tax laws in Canada allow you to claim a deduction for a prescribed portion of the asset’s cost each year it is used in your business. This deduction is called depreciation or capital cost allowance (CCA) for income tax purposes.
Each asset is added to a class, and CCA is calculated on a declining basis based on the percentage assigned to that class and the undepreciated cost of the asset in that year.
For instance, an automobile purchased for $20,000 would be included in Class 10 at a rate of 30%.
In year 1 and 2, $6,000 and $4,200 would be deducted, respectively
Year 1 20,000 X 30% = $6,000, Y2 (20,000 – $6,000) X 30% = $4,200.
The remaining undepreciated cost of $9,800 (20,000 – 6,000 – 4,200) would be deducted until the asset is reduced to zero or disposed of.
Understanding the CCA Half-Year Rule
The half-year rule implies that during the year you acquire a new business property, you can only deduct half of the regular CCA,even if you acquired it in an early part of the year.
It is how the CRA balances out timing because most individuals do not utilize a new asset throughout the year after they buy it.
Why Does It Exist?
So, with no rule in place, the business would have been able to purchase a high-price item on December 30 and get to take a year of depreciation, which would not have been logical. The six-month regulation makes things equal and comparable.
How to Calculate Capital Cost Allowance
Calculating CCA might appear complex, given the various considerations involved. If you’re seeking clarity on determining the eligible capital allowance, fret not. Below, we summarise the steps for calculating CCA and provide illustrative examples.
- Opening Balance: Begin with the opening balance at the start of the year, also called the Undepreciated Capital Cost (UCC).
- Additions: Account for any additions to the current year’s asset class.
- CCA Half-Year Rule: Calculate 50% of the additions as per the half-year rule.
- Dispositions: Factor in the amount received from asset disposals.
- The base for CCA: Compute the base for CCA using the formula
Opening balance + Additions – Half-year rule – Dispositions.
- CCA Rate: Utilize the prescribed CCA rate for the specific asset class.
- CCA Deduction: Calculate the CCA deduction as follows: Base for CCA x CCA rate.
- Ending Balance: Determine the closing balance by subtracting the CCA deduction from the opening balance.
For years, when you dispose of an asset, employ the subsequent CCA formula. If multiple assets are part of the same class, the earlier calculator remains applicable.
The formula below is specifically for situations where you are closing the entire class.
- Opening Balance: Commence with the opening balance, denoted as the Undepreciated Capital Cost (UCC).
- Dispositions: Consider the amount received from asset disposals.
- Recapture or Terminal Loss: Compute the difference between the opening balance and dispositions.
If the outcome is negative, it signifies a recapture, which must be reported as income. Conversely, if the positive result indicates a terminal loss, it should be reported as a loss on your tax return.
Step-by-Step CCA Calculation Example
When you are self-employed, such as a psychotherapist, you purchase business items (furniture, laptop, office equipment) and this expenditure (which doesn’t qualify as a weekly stock purchase) generally cannot be incurred as a deduction in the tax year in which it is incurred. Instead, you are allowed to write off a little every year in CCA (Capital Cost Allowance).
Here’s a simple example to show how it works.
Step 1: Start with your purchase
Let’s say you buy office furniture for $10,000.
This type of asset is in Class 8, which has a 20% CCA rate.
Step 2: Apply the half-year rule
In the first year, you can only claim half of the CCA rate. So instead of 20%, you can claim 10%.
Calculation
$10,000 × 10% = $1,000 CCA (Year 1 deduction)
At the end of Year 1, your remaining balance, called UCC (Undepreciated Capital Cost), is:
$10,000 − $1,000 = $9,000
Step 3: Next year’s deduction
In Year 2, you can now claim the full 20%.
$9,000 × 20% = $1,800 CCA
New balance: $9,000 − $1,800 = $7,200
Step 4: Keep repeating each year
Every year, you take 20% of the remaining balance. So it gets smaller and smaller over time.
| Year | Opening Balance | CCA Rate | Deduction | Closing Balance |
| 1 | $10,000 | 10% | $1,000 | $9,000 |
| 2 | $9,000 | 20% | $1,800 | $7,200 |
| 3 | $7,200 | 20% | $1,440 | $5,760 |
| 4 | $5,760 | 20% | $1,152 | $4,608 |
Step 5: If you sell the item
Should you subsequently realise a higher price on the furniture than the balance left, you will have a recapture (you pay tax on this margin). In the event that you sell it at a loss, you will have a terminal loss (you can deduct it).
Simple rule of thumb:
- Sell high: recapture (extra income)
- Sell low: terminal loss (extra deduction)
CCA Calculation Formula
The Capital Cost Allowance (CCA) formula is the simple way to figure out how much you can deduct each year for business assets (like office furniture, computers, or therapy equipment).
Here’s the basic formula:
CCA=(UCC at beginning of year+Additions−Dispositions)×CCA Rate×Half-Year Rule (if applicable)
Let’s break that down:
- UCC (Undepreciated Capital Cost): The leftover balance of your asset’s value from previous years after claiming CCA.
- Additions: The cost of any new business assets you bought during the year (e.g., new desk, laptop, chair).
- Dispositions: The amount you received if you sold or traded in an old asset.
- CCA Rate: The percentage assigned to that type of asset (for example, Class 8 = 20%, Class 50 = 55%).
Half-Year Rule: In the year you buy a new asset, you can only claim half of the CCA for that first year.
Capital Cost Allowance vs Tax Depreciation
CCA and depreciation are closely related concepts, although they possess distinct characteristics.
Capital Cost Allowance (CCA) represents a tax deduction, whereas depreciation is an accounting practice. Essentially, CCA corresponds to the accounting term “depreciation.”
The utilization of CCA deductions adheres to regulations established by the Canada Revenue Agency (CRA), predominantly guided by CRA CCA classes. These regulations dictate the permissible deduction amounts.
In contrast, depreciation involves accountants estimating an asset’s anticipated useful life and spreading its value decrease across periodic intervals according to that projection.
Depreciation accurately mirrors an asset’s diminishing value on the financial records. Moreover, various depreciation methodologies are available within Canadian accounting, allowing accountants the discretion to choose the most suitable approach.
For the sake of simplicity, CCA and depreciation often align. Many accountants opt to depreciate assets in alignment with CCA guidelines, streamlining the tax filing process.
This strategy minimizes administrative complexities since only one calculation needs to be tracked instead of managing two separate calculations. Nonetheless, this approach doesn’t necessarily guarantee that the recorded depreciation always precisely corresponds to an asset’s true useful life.
What is Undepreciated Capital Cost (UCC)?
You might encounter the acronym UCC in the context of taxation. Undepreciated Capital Cost refers to the portion of an asset’s value that remains unclaimed for Capital Cost Allowance (CCA) deductions. In simpler terms, it signifies the starting balance used at the beginning of a fiscal year to compute CCA.
Special Regulations
Curious about the half-year rule for CCA? It’s a great question! When you acquire an asset within a year, you can deduct only half of the eligible CCA for that year. This is commonly referred to as the half-year rule or the 50% rule.
Then there’s the “available for use” rule. This guideline stipulates that CCA can only be claimed once the asset is prepared for utilization.
Suppose you procure a property that requires renovation; until those renovations are complete, the property isn’t considered ready for use. Only after the renovations are finished would it be deemed available for use.
Lastly, in the year of asset disposal, you’ll encounter recapture or terminal loss. These terms are employed in CCA tax scenarios to denote gains or losses. In essence, if you realize a profit from selling an asset, you’d face recapture, leading to additional income on your tax return.
Conversely, if the sale results in a loss, you’d incur a terminal loss, a deduction on your tax return.
Capital Cost Allowance (CCA) Tips
Tax Tip: Not claiming CCA to offset non-capital losses. For example, if you have non-capital losses of $10,000 and CCA of $5,000, you may want to only claim $5,000 of CCA in 2023. This will allow you to offset your taxable income from the non-capital losses.
Tax Tip: Avoiding recapture on the disposition of assets. For example, if you sell a piece of equipment for $12,000 that you had claimed CCA on, you will have a recaptured gain of $2,000. This is because the disposition value of the equipment ($12,000) exceeds the undepreciated cost of the equipment ($10,000).
Tax Tip: Claiming CCA on appreciating assets. For example, if you buy a piece of land for $10,000 and expect it to be appreciated, you may want to not claim CCA on the land. This is because the gain on the disposition of the land would be taxed at a lower rate if treated as a capital gain.
Tax Tip: In the first year the asset is acquired, only ½ of the CCA can be claimed. If you plan on purchasing assets early in the next business year, you should consider expediting the purchase before the year-end to claim ½ of the CCA in the current year and the full CCA deduction in the next year.
Tax Tip: CCA is a permissive deduction, meaning you can claim any amount up to the maximum prescribed limit for the year. If you have non-capital losses, it may be advantageous not to claim CCA until all non-capital losses have been claimed. The reason is that non-capital losses expire after a defined carry-forward period, whereas CCA has no limitation and can be carried forward indefinitely.
Tax Tip: Generally, on asset disposition, a deductible loss (terminal loss) would occur if the undepreciated cost exceeds the disposition value. If the disposition value exceeds the undepreciated cost, a taxable gain (recapture) would be recognized.
In certain circumstances where you expect the asset to appreciate and may consider selling it in the near term, it may be beneficial not to claim CCA to avoid the gain on recapture, which would be 100% taxable. In this situation, the appreciation in value over the original purchase price at the time of sale would be a capital gain and would only be taxed at 50%.
CCA Updates for 2026
Phase-out of the Accelerated Investment Incentive (AII) / enhanced first-year allowance
- The enhanced first-year allowance that gave very large first-year deductions is being phased out between 2024 and 2027:
- 2024–2025: enhanced first-year allowance equals 75% (where applicable).
- 2026–2027: enhanced first-year allowance equals 55% (where applicable).
- From 2028 onward: the enhanced allowance is no longer available and normal CCA rules (including the half-year rule where applicable) apply.
- 2024–2025: enhanced first-year allowance equals 75% (where applicable).
- (This phase-out applies across a range of eligible property classes that previously benefitted from accelerated first-year treatment.) Canada.ca+1
Immediate expensing (100% first-year deduction) for certain productivity-enhancing assets — limited window
- Classes: generally Class 44, Class 46 and Class 50 additions.
- Timing: property must be acquired after April 15, 2024 and become available for use before January 1, 2027 to get immediate expensing. Property becoming available for use in 2027 may still interact with AII rules — check specific guidance. Canada.ca+1
Accelerated CCA for new purpose-built rental housing (increased rate)
- Rate: increased from 4% → 10% (accelerated CCA) for eligible new purpose-built residential rental properties.
- Eligibility window: construction must begin after April 15, 2024 (some guidance states “begin construction after April 15, 2024 and before Jan. 1, 2031”) and the building must be available for use before January 1, 2036. Also meet unit/tenancy tests (e.g., number of units, % held for long-term rental). Verify the construction-start and completion/available-for-use dates for each project. Parliamentary Budget Officer+1
Clean energy / certain other accelerated classes follow AII phase-out schedule
- Enhanced/accelerated allowances for eligible clean energy / energy-efficient property (examples include certain Class 43 assets and other technology-specific classes) are being reduced under the same multi-year phase-out (75% → 55% → none) depending on the class and when the asset becomes available for use. Confirm class-specific rules for Classes 43.1/43.2 and related categories. PwC Tax Summaries+1
Passenger vehicle limits (business use) — updated ceilings for 2025 and ongoing relevance for 2026 planning
- Class 10.1 passenger vehicle capital cost limit increased from $37,000 → $38,000 (before tax) for vehicles acquired on or after January 1, 2025.
- Zero-emission passenger vehicles (Class 54) limits remained at $61,000 for 2025. These limits matter when calculating allowable CCA for vehicles acquired in 2025–2026. Canada.ca+1
“Available for use” timing remains the determinative fact
- Whether accelerated/temporary measures apply depends on when the property becomes available for use, not merely when purchased. Maintain contemporaneous documentation showing the date property was placed in service / available for use. (This is especially important around the phase-out windows.) Canada.ca
Provincial harmonization and administrative guidance — verify locally
- Some provinces may harmonize with federal measures differently and CRA/Finance Canada may publish administrative guidance (CRA pages and Budget supplementary information/draft legislation). Always confirm via CRA notices and the enacted legislation, not only the Budget proposals. budget.canada.ca+1

FAQs
1. What are the risks of claiming CCA?
Here are some of the risks of claiming CCA:
- Recapture: If the asset is disposed of for more than its undepreciated cost, the business may have to pay tax on the gain. This is called recapture.
- Timing: The timing of CCA deductions can affect the amount of tax that a business pays. For example, if a business claims CCA in a year when it has a lot of other deductions, it may not benefit as much from the deduction.
- Complexity: The calculation of CCA can be complex, and businesses may need to hire a tax advisor to help them.
- Errors: If a business makes a mistake in calculating CCA, it could be subject to penalties from the CRA.
2. What is the half year rule for CCA?
The half-year rule is a rule that applies to the calculation of CCA. It states that you can only claim half of the CCA rate in the year that you acquire an asset. This is because the government considers that you have only used the asset for half of the year in the year of acquisition.
For example, if you acquire an asset on January 1, 2023, you can only claim 1/2 of the CCA rate for 2023. You would then claim the full CCA rate for 2024 and subsequent years.
There are a few exceptions to the half-year rule. For example, the rule does not apply to assets acquired in the last 3 months of the year. In this case, you can claim the full CCA rate for the year of acquisition.
3. What is the accelerated investment incentive?
The accelerated investment incentive is a temporary measure that allows businesses to claim a higher CCA rate on certain types of property, such as machinery and equipment. This incentive can help businesses recover the cost of these assets more quickly.
The accelerated investment incentive is available for assets that are acquired between January 1, 2022 and December 31, 2023. The higher CCA rate is 30% for machinery and equipment, and 50% for electric vehicles.
The accelerated investment incentive is a valuable tax break for businesses that are investing in new equipment. It can help businesses save money on taxes and improve their bottom line.
4. What are the different methods of calculating depreciation?
There are several different methods of calculating depreciation, including the straight-line method, the declining-balance method, and the sum-of-years’-digits method. The method used will depend on the type of asset and the business’s financial situation.
The straight-line method is the simplest method of calculating depreciation. It involves depreciating the asset over its useful life in equal installments.
The declining-balance method is a more accelerated method of depreciation. It involves depreciating the asset at a higher rate in the early years of its life and at a lower rate later.
The sum-of-years’-digits method is a method that takes into account the asset’s useful life. It involves depreciating the asset at a rate that is proportional to the number of years of remaining useful life.
The best method of calculating depreciation will depend on the asset and the business circumstances. It is important to consult with a tax advisor to determine the best method for your situation.
5. Can I choose not to claim CCA in a given year?
Yes, you can. Claiming Capital Cost Allowance (CCA) is completely optional. You decide whether or not to claim it in any given year and how much to claim. Many business owners choose to delay or reduce their CCA claim in profitable years so they don’t lower their Undepreciated Capital Cost (UCC) too quickly. This can be helpful if they plan to sell the asset soon or want to save that deduction for a future year when their income might be higher. If you skip CCA in one year, the unused amount simply remains available for future years.
6. What happens if I sell an asset after claiming CCA?
When you sell an asset that you’ve previously claimed CCA on, you need to compare the sale price to the remaining balance in that asset’s CCA class. If you sell it for more than the remaining UCC but less than the original purchase price, the difference is called a recapture, and it is added back to your income for tax purposes. If you sell the asset for less than the remaining UCC and you no longer have any other assets in that class, you can claim a terminal loss, which is a deduction that reduces your taxable income. In simple terms, selling for more can increase your taxable income, while selling for less can give you a deduction.
7. Can CCA be carried forward to future years?
Yes, it can. If you choose not to claim CCA in a particular year, the amount you could have claimed simply stays in your UCC balance and carries forward to future years. This flexibility allows you to use CCA as a tax planning tool. You can wait to claim it in a year when your business income is higher, helping yoau reduce taxes more strategically.
8. How does the CCA deduction affect business taxes in Canada?
CCA directly lowers your taxable business income. For example, if your business earns $80,000 and you claim $5,000 in CCA, your taxable income drops to $75,000. Since CCA is a non-cash expense, it reduces your taxes without affecting your cash flow in that year. However, claiming too much CCA too quickly can reduce your future deductions and may result in a recapture later if you sell the asset for more than its remaining UCC.
