A $4,000 workstation is not automatically a $4,000 deduction in the year it is purchased. Equipment acquired for an IT contracting business is capital property. Under the Capital Cost Allowance rules, capital property is generally recovered through a pool that carries forward year to year. How quickly the deduction can be claimed depends on which CCA class the equipment belongs to, whether a first-year incentive applies, and what portion of the asset is used for business.
Capital Property vs. Current Expense
The first question with any equipment purchase is whether it is a capital expenditure or a current expense. A current expense provides a benefit within the current fiscal year and is deducted in full in the year it is incurred. A capital expenditure provides a benefit that extends beyond the year, and the cost is recovered gradually through CCA rather than immediately.
Equipment with a useful life beyond one year is capital property. A laptop, workstation, server, phone, or external monitor is capital property. Software that is not a subscription and not embedded in hardware may also be capital, depending on the nature of the acquisition. SaaS subscriptions — monthly or annual fees for cloud-based software — are current expenses and do not go through a CCA class at all.
The distinction matters because the timing of the deduction changes. For a sole proprietor with net income pushing into a higher bracket in the current year, a capital purchase does not produce the same immediate relief as a current expense would. For an incorporated contractor, the timing difference affects both the corporate T2 and the subsequent compensation decisions.
CCA Classes for IT Equipment
Equipment is grouped into classes. Each class has a prescribed rate and its own running pool balance, called the Undepreciated Capital Cost. Additions increase the UCC; CCA claimed and proceeds from disposals reduce it. The pool carries forward indefinitely until the class is wound down.
Class 50 — Computers and Workstations (55%)
Class 50 covers general-purpose electronic data processing equipment and systems software for that equipment, including ancillary data processing equipment. In practice, Class 50 applies to desktop computers, laptops, tablets used primarily as computers, workstations, servers, and monitors and peripherals acquired as part of a computer system. Data network infrastructure equipment is generally a separate category, usually Class 46 when acquired after March 22, 2004.
The prescribed CCA rate is 55% on the declining balance. On a $4,000 workstation, the maximum Class 50 CCA in a full-rate year is $4,000 multiplied by 55% = $2,200. The remaining $1,800 carries forward as the UCC for future years. In an acquisition year, the regular half-year rule would reduce the first-year claim before any first-year incentive is considered.
Class 8 — Peripherals, Phones, and Other Equipment (20%)
Class 8 is the residual class for tangible depreciable property not included in another class. For IT contractors, this typically captures standalone printers, scanners, external hard drives that do not form part of a computer system, smartphones, and other mobile devices that function primarily as communication tools rather than general-purpose computers.
The prescribed rate is 20% on the declining balance. Class 8 equipment depreciates more slowly than Class 50. A $1,200 phone in Class 8 generates $240 in CCA in a full-rate year, before any half-year or incentive adjustment.
Classifying a device as Class 50 or Class 8 depends on its primary function. A tablet or device used primarily for computing and technical work can be Class 50. A phone that runs apps but whose primary function is communication is generally Class 8. Where the classification is not clear, a CPA should confirm the appropriate class before it is reported.
Class 12 — Application Software (100%)
Application software that is not systems software and not embedded in hardware belongs to Class 12, which has a 100% CCA rate. CRA’s guide states that Class 12 computer software is subject to the half-year rule, so the regular first-year deduction is 50% of the cost. Some other Class 12 property, such as most small tools, is not subject to the half-year rule, but that exception does not apply to Class 12 software.
Systems software — the operating system acquired with a computer — is generally included in the cost of the hardware and placed in Class 50 with the device. Application software purchased separately goes in Class 12. A one-time software purchase (not a subscription) for a development tool, design application, or productivity suite typically belongs to Class 12.
The Half-Year Rule
In the year of acquisition, the half-year rule limits CCA to 50% of the normal rate on net additions that are subject to the rule. A Class 50 asset acquired mid-year receives 27.5% rather than 55% under the regular rule. A Class 8 asset receives 10% rather than 20%. Class 12 software receives 50% rather than 100% unless a first-year incentive changes the calculation.
Dispositions matter when calculating net additions. If assets are added and disposed of in the same year, the proceeds can reduce the additions before the 50% adjustment is calculated. A year with only a disposition does not create a half-year adjustment for that disposed asset; the disposition reduces the UCC and may create recapture or terminal loss depending on the class balance.
For contractors who acquire equipment late in the fiscal year, the half-year rule means the first-year deduction is the same whether the asset was purchased in January or November. The rest of the CCA follows in subsequent years based on the declining UCC balance.
First-Year Incentives: DIEP, AIIP, and RIIP
For new equipment acquired in 2026, the federal immediate expensing incentive should not be treated as a generally available CCPC election. It was a temporary measure for designated immediate expensing property (DIEP). For CCPCs, CRA’s 2024 T2 guide described DIEP as eligible property acquired after April 18, 2021, that became available for use before 2024. For individuals and all-individual Canadian partnerships, CRA’s 2025 T4002 guide describes immediate expensing property as generally needing to be acquired after December 31, 2021, and available for use before 2025.
For tax years where DIEP was available, the federal limit was $1.5 million per taxation year. Associated eligible persons or partnerships shared this limit and had to allocate it between them. The incentive applied only in the year the property became available for use, and unused annual capacity could not be carried forward.
The more current first-year rules for new equipment are the Accelerated Investment Incentive (AIIP) and the reaccelerated investment incentive (RIIP). CRA’s 2025 and 2026 forms use AIIP for qualifying property acquired before 2025 and available for use before 2028, and RIIP for qualifying property acquired after 2024 and available for use before 2034. These rules generally suspend the half-year rule for eligible property, but the result depends on the class, acquisition date, available-for-use date, and anti-avoidance restrictions.
Class 50 computer equipment has an especially important current rule. CRA’s 2025 guide says new Class 50 additions acquired after April 15, 2024, and available for use before 2027 are eligible for an enhanced first-year deduction of 100%, subject to the AII/RII restrictions. That is not the same as the old $1.5 million DIEP election, even though the practical result for a qualifying Class 50 computer can also be a full first-year deduction.
The property must be available for use in the year. Equipment ordered but not yet received or operational may not satisfy the available-for-use rules, depending on the circumstances. Equipment purchased, received, and in use before the fiscal year-end generally qualifies in that year.
Worked example under regular half-year rules: An Ontario corporation buys a $4,000 workstation and a $1,200 phone in its December 31 fiscal year. Without a first-year incentive, the first-year CCA claim would be $1,100 for the workstation (Class 50, 55% x 50%) and $120 for the phone (Class 8, 20% x 50%), for a total of $1,220. If the workstation qualifies for the current Class 50 enhanced first-year rule, the workstation may be fully deductible in the first year, while the phone still follows the Class 8 calculation applicable to its acquisition year and incentive status.
The decision to accelerate CCA in a given year depends on taxable income, the compensation picture, loss restrictions, and the value of taking the deduction now rather than preserving UCC for future years. Neither choice is always better.
Mixed-Use Equipment
Equipment used for both business and personal purposes requires a business-use percentage. Only the business portion of the cost is eligible for CCA. The business-use fraction is applied to the cost before the asset enters the CCA class, limiting the depreciable amount to the business portion.
A laptop used 70% for client work and 30% for personal use has a CCA-eligible cost of 70% of the purchase price. If the laptop cost $2,500, the amount that enters the CCA class is $1,750.
The business-use percentage must be defensible. CRA’s position is that a reasonable estimate supported by the nature of the work is acceptable, but estimates that lack any factual basis are not. For a contractor who uses a device almost exclusively for client work, a high business-use percentage is easier to support. For a phone or tablet with significant personal use, the percentage should reflect actual use.
Keeping a brief record of how the percentage was determined is useful if CRA asks during a review. The type of record that supports the claim depends on the device and how it is used. A list of client-related activities, a summary of software tools used exclusively for work, or a description of the personal use limitation can each form part of the support.
If the business-use percentage changes from year to year, CRA’s T4002 guide allows an administrative method for business-and-personal property. The calculation is more involved than simply reusing the original business-use percentage, so the method should be applied consistently and documented.
Disposals and the CCA Pool
When a piece of equipment is sold, traded in, or scrapped, the lesser of the original cost and the proceeds reduces the UCC of the class. If multiple assets are in the same class, the proceeds reduce the pool balance and the remaining assets continue to depreciate.
Recapture: If the proceeds of disposition are more than the opening UCC plus the capital cost of current-year additions, the class can become negative. The negative amount is recaptured CCA and included in income. Recapture can occur even if the class is not empty.
Terminal loss: If the class has no remaining assets and the UCC exceeds the proceeds, the remaining UCC balance is a terminal loss. A terminal loss is fully deductible in the year the class becomes empty. Terminal losses are not subject to the half-year rule.
If other assets remain in the class and the class balance is still positive, there is no terminal loss; the proceeds simply reduce the running pool balance and CCA continues to be claimed on the lower UCC in future years.
For mixed-use assets, the disposal proceeds used to reduce the UCC are limited to the business-use portion, consistent with how the asset was added to the pool.
Sole Proprietors: Claiming CCA on T2125
Sole proprietors report CCA on Form T2125 in the Capital Cost Allowance section. Each class is listed separately with its opening UCC, additions, disposals, CCA claimed, and closing UCC. The total CCA reduces net business income and is carried to the T1.
The choice of how much CCA to claim in a given year is discretionary. CCA claimed can range from zero up to the maximum for the year. Claiming zero in a low-income year preserves the pool for future years when the deduction reduces income in a higher bracket. Claiming the maximum in a high-income year accelerates the deduction against the income it most offsets.
The decision to claim less than the maximum is not a loss — the UCC carries forward and CCA can be claimed in future years. The pool does not expire.
Incorporated Contractors: Schedule 8 on the T2
For an incorporated contractor, equipment acquired and used by the corporation is recorded in the corporation’s books. CCA is claimed on Schedule 8 of the T2 return. The schedule follows the same class-by-class structure as T2125 but is reported at the corporate level.
Equipment purchased by the corporation is a corporate asset. The cost goes through the corporate books, the GST/HST input tax credit is claimed at the corporate level, and the CCA deduction reduces corporate taxable income. The contractor does not claim any personal CCA for corporate-owned equipment.
If the contractor personally purchases equipment and the corporation reimburses the cost, the reimbursement should be recorded through the corporate books and the equipment should be treated as a corporate capital asset from acquisition. If the corporation does not reimburse or otherwise acquire the asset, the contractor generally should not claim personal CCA for equipment used in the corporation’s business.
Personal Services Business Limitation
If the corporation is assessed as a personal services business under the Income Tax Act, the CCA rules apply differently. A PSB is not entitled to the small business deduction and faces significantly restricted expense deductions. The deductibility of CCA on equipment held by a PSB is limited to what would be deductible by an incorporated employee, which is substantially narrower than the active business corporation rules. The PSB issue should be reviewed before relying on normal CCA treatment.

Quebec Note
Quebec follows the federal CCA class structure for most equipment, including Class 50 and Class 8. The CO-17 corporate return and the TP-80 (used with the provincial T1 equivalent for sole proprietors reporting business income) use the same class categories and rates as the federal return for most property.
Quebec may have its own treatment for accelerated CCA and temporary first-year incentives, and it should be reviewed independently rather than assumed to follow the federal result automatically. A Quebec corporation relying on enhanced first-year CCA should confirm the provincial treatment with a CPA who files CO-17 returns.

Records to Keep
For each equipment purchase:
- Receipt or invoice showing the vendor, description, and amount
- Date the asset was placed in use (to confirm the acquisition year)
- Documentation of the business-use percentage if the asset has mixed use, including how the percentage was determined
- Serial numbers or asset descriptions sufficient to identify the item if CRA requests confirmation during a review
Keep CCA schedules and UCC balances from year to year. The opening UCC of each class in the current year equals the closing UCC from the prior year. These records should be retained for as long as the class has a positive balance and for the standard six-year period after the taxation year in which the class is closed.
