Quebec CDAE Tax Credit: Fund IT Salaries and Prepare for CDAE-IA

What the CDAE is: dual administration and fiscal structure

The Tax Credit for the Development of E-Business, known in French as the Crédit d’impôt pour le développement des affaires électroniques (CDAE), is a core provincial incentive for the tech sector within Quebec business grants and tax credits. Established to stimulate high-skilled IT employment in Quebec, the program delivers combined tax relief equivalent to 30% of eligible salaries paid to qualifying computer specialists.

The CDAE operates under dual administration between two provincial entities:

• Investissement Québec evaluates corporate sector eligibility and individual job functions under the Act respecting the sectoral parameters of certain fiscal measures. The agency issues an annual corporate certificate of eligibility and individual certificates for each qualifying employee.
• Revenu Québec handles the fiscal computation and disbursement under articles 776.1.19 to 776.1.26 and 1029.8.36.0.3.79 to 1029.8.36.0.3.83 of the Taxation Act, administered through prescribed form CO-1029.8.36.DA attached to the corporate income tax return (CO-17).

Total assistance of 30% is not paid entirely as a cash refund. It combines a refundable tax credit paid directly to the business and a non-refundable corporate tax deduction that reduces income tax payable. Any unused portion of the non-refundable deduction can be carried back up to three taxation years or carried forward up to twenty taxation years.

Corporate eligibility: NAICS codes and revenue qualification tests

To obtain a corporate certificate from Investissement Québec, a company must maintain an establishment in Quebec and satisfy strict revenue tests grounded in the North American Industry Classification System (NAICS).

Both the 75% gross IT revenue test and the 50% software development test must be satisfied within the same taxation year. A corporation can qualify based on revenue from the current taxation year, or from the preceding taxation year provided it comprised at least 183 days.

The 75% arm’s-length test requires careful scrutiny. If a Quebec subsidiary develops software solely for a foreign parent corporation without the application being deployed exclusively outside Quebec, the business fails this mandatory requirement.

The six-employee rule and individual job criteria

Access to the CDAE requires a critical mass of qualified staff. The corporation must maintain a minimum of six full-time eligible employees in Quebec at all times throughout its entire taxation year.

Dropping below this six-employee threshold disqualifies the corporation for the entire fiscal period, subject to two narrow statutory exceptions:

• An unexpected employee resignation, provided the employer demonstrates active and diligent recruitment efforts to fill the vacancy quickly.
• A business startup, where eligibility begins on the exact date the sixth full-time qualifying employee commences employment.

For an employee to receive an individual certificate from Investissement Québec, three cumulative conditions must be met:

• Work full-time in Quebec with a regular schedule of at least 26 hours per week, under an employment contract with an expected duration of at least 40 weeks.
• Devote at least 75% of working hours to directly undertaking, supervising, or directly supporting eligible IT activities such as software programming, database architecture, network security, or systems integration.
• Not be a specified shareholder holding, directly or indirectly, 10% or more of any class of shares of the corporation or a related company.

Employee hours dedicated to administrative management, marketing, sales, and customer relations are strictly excluded. Furthermore, work performed under contracts where the ultimate beneficiary is a Quebec government department or public body is statutorily barred from eligible wages.

Rate schedule from 2024 to 2028 and the end of the $83,333 cap

Many online tax summaries incorrectly display a fixed 24% refundable and 6% non-refundable split. Official instructions for Revenu Québec form CO-1029.8.36.DA mandate a progressive annual shift from refundable credits to non-refundable corporate deductions.

If 50% or more of a corporation’s gross revenue stems from IT outsourcing provided to related entities (box 05c on form CO-1029.8.36.DA), each rate is cut in half, yielding 11% refundable and 4% non-refundable in 2026.

A second major reform alters eligible salary limits. For taxation years beginning before 2025, eligible salary was capped at $83,333 per employee, limiting maximum assistance to $25,000. For taxation years beginning after December 31, 2024, this rigid cap has been permanently abolished. It is replaced by an exclusion threshold based on the employee’s basic personal amount for the calendar year (approximately $18,056 for a full year), prorated to the number of eligible days.

Worked financial example: senior engineering salaries under the new threshold

Abolishing the $83,333 salary cap dramatically increases tax relief for technology companies employing highly compensated senior developers and technical architects.

Consider a Montreal software engineering firm with eight full-time eligible employees during its 2026 taxation year. A principal cloud systems architect on staff earns an annual base salary of $140,000.

1. Determining the exclusion threshold: the provincial basic personal amount is $18,056 for the calendar year. For an employee in post for 365 days, this full deductible applies.
2. Calculating net eligible salary: $140,000 minus $18,056 equals $121,944 in eligible salary base.
3. Calculating 2026 tax relief:
   • Refundable tax credit (22%): $121,944 multiplied by 22% yields $26,827.68 in direct cash funding.
   • Non-refundable corporate deduction (8%): $121,944 multiplied by 8% yields $9,755.52 in corporate income tax reduction.
   • Total fiscal assistance for this employee: $36,583.20.

Under the previous regime capped at $83,333, maximum total relief was limited to $25,000 ($20,000 refundable at 24% and $5,000 non-refundable at 6%). The post-2024 formula yields an extra $11,583.20 in net benefit on this single senior role.

Across the entire business, if the remaining seven developers earn an average salary of $95,000, their average net eligible base is $76,944 per employee. The firm secures combined tax support of $198,165.60 across all eight technical specialists.

Mandatory transition to CDAE-IA: artificial intelligence requirements

Following legislation introduced in the provincial budget, the program undergoes a fundamental structural shift: for all taxation years beginning after December 31, 2025, the regime converts into the CDAE-IA.

Corporations will no longer qualify for the credit unless their annual certificate issued by Investissement Québec confirms that their activities significantly incorporate artificial intelligence functionalities. Companies focused purely on conventional website development, routine application maintenance, or basic software implementation without advanced algorithmic components will lose eligibility.

To meet the technical standards established by Investissement Québec, engineering teams must document substantive AI capabilities, including:

• Supervised, unsupervised, or reinforcement machine learning models embedded in products.
• Natural language processing (NLP) for contextual search, document intelligence, or semantic analysis.
• Computer vision algorithms applied to image classification, pattern recognition, or automated inspection.
• Advanced predictive analytics and automated decision engines driving core business workflows.

Two transitional rules protect earlier claims:

1. Fiscal periods beginning on or before December 31, 2025 remain evaluated under conventional CDAE rules without mandatory AI criteria.
2. Unused non-refundable tax deductions earned in taxation years beginning before January 1, 2026 can be carried forward up to twenty years, even if the corporation does not obtain a CDAE-IA certificate in future periods.

How to apply: filing deadlines and Revenu Québec tax reporting

Claiming the CDAE follows a strict two-stage process spanning Investissement Québec and Revenu Québec.

1. The certificate application must be submitted electronically to Investissement Québec no later than the end of the 15th month following the close of your fiscal year. A discretionary grace period up to the 18th month may be considered for exceptional circumstances. Filing after 18 months results in automatic, irrevocable statutory forfeiture. The application requires technical project descriptions, NAICS revenue breakdowns, AI technical documentation for CDAE-IA, and individual employee files. Average review time at Investissement Québec spans 60 to 90 days.
2. Corporate tax filing occurs through Revenu Québec using prescribed form CO-1029.8.36.DA attached to your corporate tax return (CO-17). This filing must take place within 12 months of the statutory CO-17 filing due date, or within 3 months of the date Investissement Québec issues your certificates, whichever date is later.

On the CO-17 corporate return, approved amounts are entered under specific codes:

• Lines 440p to 440y, code 86: refundable tax credit paid directly to the company.
• Lines 421b to 421f, code 306: current-year non-refundable tax deduction.
• Lines 421b to 421f, codes 307 and 308: non-refundable deductions carried forward from prior years (code 307) or carried back (code 308).
• Lines 425aa/bb (code 74) or line 443: special recovery tax if certificates are revoked upon audit.

Stacking rules: interactions with SR&ED, CRIC, C3i, and MFOR

The CDAE functions alongside several federal and provincial business programs, requiring careful coordination to prevent overlapping claims on identical expenditures.

For scientific research, you cannot claim the CDAE and the Quebec SR&ED tax credit or the Quebec CRIC tax credit on the same employee hours. A clear functional separation is required:

• Hours dedicated to resolving technical uncertainties, testing novel algorithms, or experimental development belong under SR&ED or the R&D stream of the CRIC.
• Hours dedicated to application coding, systems deployment, cloud architecture, and ongoing software maintenance qualify under the CDAE.
• The same technical employee can be split between both programs during the year, provided you maintain contemporaneous daily timesheets detailing separate tasks.

With the C3i tax credit, synergy is immediate without expenditure conflicts. The C3i funds the acquisition of IT servers and ERP management software packages, while the CDAE covers the development salaries of internal specialists building, customizing, or maintaining those systems.

Finally, an IT employer can combine the CDAE with the Services Québec MFOR training grant. While the CDAE offsets ongoing production salaries, MFOR can reimburse up to 65% of external training costs required to upskill developers on new programming frameworks, cloud tools, or AI technologies.
