To attract $1 trillion in additional investment, the federal government announced the Productivity Mega Deduction on September 15, 2026. It builds on the super deduction announced in Budget 2025, which allows businesses to immediately expense about 15% of spending on eligible capital assets. What sets the newly proposed mega deduction apart is
- Immediate expensing of 100% of the cost of eligible assets in the year it becomes available for use.
- The deduction would be permanent, bringing certainty to projects with long development and operating periods.
Compared with the Budget 2025 measures, the mega deduction covers assets and expenses, which represent about two-thirds of capital investment. Finance Canada estimates the new deduction to halve the marginal effective tax rate from 13% to 6.4% and add $36 billion in fiscal cost over five years, beginning in 2026-27.
The new deduction aims to lower the cost of capital and strengthen the business case for modern equipment. Let’s see how.
What Is the Productivity Mega Deduction?
The Canadian tax system uses the Capital Cost Allowance (CCA) schedule, which divides capital property into different classes. The CCA rate for each class of property is prescribed in the Income Tax Regulations, allowing taxpayers to deduct the cost of depreciable property over several years on a declining-balance basis.
The Productivity Mega Deduction will reduce the time to recover capital cost from multiple years to the year the eligible asset becomes available for use. The measure applies to eligible depreciable property acquired and Canadian development expenses incurred on or after September 15, 2026.
Suppose ABC company orders five vehicles for business in October 2026 and they are delivered in March 2027. The company can deduct 100% of the cost of these vehicles in the 2027 tax year when the vehicles are delivered and begin contributing to the business. This will free up cash sooner.
The extent to which a taxpayer can use the Productivity Mega Deduction depends on that year’s taxable income. Individuals and partnerships with one or more individual partners cannot use this deduction to create or increase a loss.
General Eligibility of Mega Deduction
For capital property to be eligible for the new deduction, it must have been acquired on or after September 15, 2026, and must not be on the excluded list.
The excluded list:
- Class 1 and 3 buildings, including manufacturing and processing buildings. However, they are eligible for Budget 2025 deductions.
- Classes 14 and 14.1 franchises, licences, goodwill
- Class 51 regulated natural gas distribution pipelines
- Certain class 10/10.1 vehicles
- Schedule V and VI property
The Budget 2025 measure covers capital assets, including machinery, equipment, and buildings used for manufacturing and processing; clean energy generation and energy conservation equipment; zero-emission vehicles; patents; data network infrastructure; and computers. Properties that do not qualify for any productivity deductions will continue to receive enhanced first-year deduction under the existing Accelerated Investment Incentive.
The Included List:
- Machinery, equipment, and technology; fibre-optic cable
- Mining property; oil and gas pipelines
- Software; R&D and Canadian development expenses
- Computer equipment; aircraft and vehicles (outside classes 10/10.1 restrictions)
- Patents; rail track; bridges and roads
For instance, ABC company spends $2 million to build a manufacturing plant and $100,000 to buy equipment. It cannot immediately expense the entire $2 million for the building, but it can expense the entire $100,000 for equipment as it qualifies for the Mega Deduction. However, it can claim accelerated CCA on the building cost because it qualifies under the Budget 2025 measure.
How Mega Deductions Work in the Acquisitions of Used Assets
Assets in the eligible list, whether new or used, qualify for the proposed deduction. However, pre-owned or used assets must meet two criteria:
- neither the taxpayer nor a non-arm’s length person previously owned the eligible asset
- property was not transferred on a tax-deferred “rollover” basis.
This rule matters most in a merger and acquisition or corporate reorganization, as such deals often involve purchasing used assets.
The new deduction is still a draft proposal and has not yet been enacted into law. Once enacted, the legislative amendments will apply retroactively to the date of their initial announcement. Businesses should start assessing the implications of the new tax incentives now and plan future capital purchases accordingly.
How Can Businesses Prepare for Productivity Mega Deduction
- The key eligibility requirement for the mega deduction is the time of acquisition. Assets purchased on or after September 15, 2026, will qualify if the proposal becomes law. Businesses can plan capital spending relative to that date.
- The second eligibility criterion is the CCA class. Businesses can confirm whether the asset falls under the eligible CCA class before buying it.
- 100% expensing will significantly change the timing of CCA deductions and the deferred tax position, requiring changes to capital budgets and tax provisions.
- The mega deduction excludes some assets. Businesses can analyze other incentives for excluded property such as Scientific Research and Experimental Development (SR&ED), the Clean Economy investment tax credits, and the Accelerated Investment Incentive.
The mega deduction is good news for many businesses, but you should think it through. What if the business cannot claim 100% of the expense? Will the differences between federal and provincial treatment of CCA materially change the result? What happens at the time of asset disposal? You must comply with anti-loss creation rules that will apply to individuals, and to partnerships with individual members.
Availing yourself of the mega deduction also requires you to prepare and maintain documentation to prove compliance.
