Frequently Asked Questions
How does the increased small business deduction threshold affect my corporation?
If your CCPC has active business income between $500,000 and $550,000, you’ll now benefit from the 9% federal rate (12.2% combined with Ontario) on the additional income. This can save approximately $7,150 in annual tax on the incremental $50,000. However, if your taxable capital exceeds $10 million, you may still face SBD clawback that could offset this benefit.
What clean technology investments qualify for 100% first-year CCA?
Qualifying property includes zero-emission vehicles, EV charging stations, solar and wind energy equipment, geothermal systems, heat pumps, energy-efficient HVAC, battery storage, and specified energy recovery equipment. The property must be acquired and available for use before 2030. Work with your CPA to confirm specific equipment eligibility and documentation requirements.
How do the enhanced SR&ED provisions affect my technology company?
The increased expenditure limit from $3 million to $3.5 million means you can claim refundable credits (40% federal rate) on an additional $500,000 of qualifying expenditures. For a qualifying small business, this represents an incremental $200,000 in refundable credits. Combined with Ontario’s OITC (8%), total credits can reach 48% on qualifying R&D.
When does the Digital Services Tax take effect, and does it apply to my business?
The DST becomes effective January 1, 2027, but only applies to businesses with global revenues exceeding 750 million and Canadian digital services revenue exceeding $20 million. Most Canadian SMBs won’t be directly subject to DST, but may experience indirect cost increases if platforms (Google, Meta, Amazon) pass through their DST liability in the form of higher advertising or marketplace fees.
How should I adjust my year-end tax planning given these budget changes?
Key year-end actions include: (1) modeling whether to accelerate or defer income to optimize SBD utilization, (2) accelerating qualifying clean technology purchases to access 100% CCA, (3) documenting SR&ED activities under enhanced requirements, (4) reviewing debt structures under EIFEL rules, and (5) ensuring beneficial ownership and other compliance reporting is current. Schedule a planning consultation with Insight Accounting CPA at (905) 270-1873 for personalized guidance.
What are the tax implications of the carbon price increase to $95 per tonne?
The carbon price increase will flow through to higher fuel and energy costs, affecting both direct consumption and supply chain costs. For an average business, expect approximately 2.3 cents per liter increase in gasoline/diesel costs. Carbon-intensive operations should evaluate: (1) energy efficiency investments eligible for accelerated CCA, (2) process modifications to reduce emissions, and (3) carbon pricing impact on product pricing and competitiveness.
How do I know if my business will be affected by the EIFEL interest limitation rules?
EIFEL applies if your annual interest expense exceeds the greater of (a) 30% of tax EBITDA or (b) $250,000. If your business has significant debt financing relative to earnings, conduct an EIFEL impact analysis. Highly leveraged real estate, private equity-backed businesses, and companies with acquisition debt are most likely to be affected. Your CPA can model your specific exposure and plan mitigation strategies.
