Salary & Wages

What Can Be Claimed

  • Base salary for time spent on SR&ED activities
  • Taxable benefits (health insurance, car allowance, etc.)
  • Bonuses related to SR&ED work
  • Employer's share of CPP, EI, and other statutory contributions

Time Allocation

Employees rarely spend 100% of their time on SR&ED. You must:

  • Track actual time spent on SR&ED activities
  • Maintain timesheets, project logs, or other documentation
  • Be prepared to justify allocations during CRA review

Who Qualifies

EligibleNot Eligible
Engineers performing R&DAdministrative assistants
Scientists conducting experimentsSales personnel
Technicians supporting SR&EDHR staff
Technical project managersGeneral management
Programmers developing new technologyIT support for routine operations

Materials Consumed

Materials consumed are those that are used up, destroyed, or rendered valueless during SR&ED activities.

Examples

  • Chemicals used in experiments
  • Electronic components destroyed during testing
  • Raw materials consumed in failed prototypes
  • Testing samples that cannot be reused

Requirements

  • Materials must be directly attributable to SR&ED
  • You must be able to document the cost and usage
  • Materials used for commercial production do not qualify

Materials Transformed

Materials transformed are those incorporated into a prototype or product that cannot be sold at fair market value.

Key Distinction

Materials ConsumedMaterials Transformed
Used up or destroyedIncorporated into something
No longer existStill exist but not sellable
Full cost claimableCost minus any resale value

Examples of Materials Transformed

  • Components built into a prototype that will be scrapped
  • Materials incorporated into test equipment
  • Parts used in a one-off device for internal testing
  • Raw materials transformed into unsellable test products

Important Rules

Calculate the claim:

Claimable Amount = Cost of Materials - Proceeds from Sale (or Fair Market Value)

Documentation Required

  • Purchase invoices for materials
  • Records showing materials were used in SR&ED
  • Evidence that prototypes were not sold (or documentation of sale proceeds)
  • Bill of materials for prototypes

Contract Expenditures

When you hire third parties to perform SR&ED on your behalf — meaning you control the work and it's performed as if you did it yourself.

Arm's Length vs Non-Arm's Length

TypeITC EligibilityDeductible
Arm's Length80% of contract amountYes
Non-Arm's LengthNot eligible for ITCYes (deductible only)

Eligibility Requirements

  • Work must be performed in Canada
  • The contractor performs SR&ED work on your behalf (you control the work)
  • You must document the arrangement and the SR&ED performed

What Qualifies

  • R&D consulting services
  • Laboratory testing services
  • Engineering design for SR&ED projects
  • Technical analysis and experimentation

What Does NOT Qualify

  • General IT consulting (non-R&D)
  • Legal or accounting services
  • Marketing research
  • Foreign contractors or work performed outside Canada

Overhead Costs

You have two methods to calculate overhead: Proxy Method or Traditional Method. You must choose one method per tax year when filing your SR&ED claim.

Proxy Method (Most Common)

The Prescribed Proxy Amount (PPA) simplifies overhead calculation by using 55% of the salary base (in effect since 2014).

Calculation: PPA = Salary Base × 55%

The salary base includes salaries and wages of employees directly engaged in SR&ED activities in Canada. Special rules apply for specified employees (shareholders or their relatives) which may limit amounts included.

Key Points:

  • No tracking of actual overhead costs required
  • Investment tax credits (ITCs) are earned on the PPA
  • The PPA is not deductible from income — it's only used to calculate ITCs
  • Actual overhead expenses are deducted as ordinary business expenses

Traditional Method

Claim actual overhead and other expenditures directly related and incremental to SR&ED.

Eligible Costs:

  • Rent for SR&ED workspace (proportional allocation)
  • Utilities (heat, light, power) for SR&ED areas
  • Equipment maintenance and repairs
  • Insurance for SR&ED facilities/equipment
  • Supplies not directly consumed in SR&ED

Requirements:

  • Must specifically identify and allocate all overhead costs to SR&ED
  • Detailed records and justification required for each expenditure
  • Overhead must be directly related and incremental to SR&ED activities

Third-Party Payments

Payments to approved entities to conduct SR&ED — different from contract expenditures because you do NOT control the actual work performed.

Key Difference from Contracts

Contract ExpendituresThird-Party Payments
You control the SR&ED workYou do not control the work
Work done "on your behalf"Work done independently
80% eligible (arm's length)100% eligible
Reported on lines 340/345Reported on line 370

Eligible Recipients

  • Universities - Approved Canadian post-secondary institutions
  • Colleges - Canadian colleges with R&D capabilities
  • Research institutes - CRA-approved organizations
  • Hospital research facilities

Requirements

  • Payment must be to an approved entity
  • The SR&ED must be carried out in Canada
  • Work must be related to your business
  • You must have the right to exploit the results of the SR&ED

Special Treatment

  • 100% of payments are claimable (vs. 80% for arm's length contracts)
  • Eligible on a cash basis — when the payment is made, not when work is performed
  • May qualify for enhanced tax credit rates

Capital Expenditures

What Qualifies

Capital property acquired on or after December 16, 2024, used all or substantially all (90% or more) for SR&ED activities in Canada:

  • Machinery and equipment for R&D
  • Laboratory equipment
  • Testing apparatus
  • Specialized tools for SR&ED

Shared-Use Equipment

If equipment doesn't meet the 90% SR&ED usage threshold but is still used partly for SR&ED, it may qualify as shared-use equipment — allowing a proportional amount of the cost to be eligible.

Refundability for CCPCs

For Canadian-Controlled Private Corporations (CCPCs) eligible for the enhanced 35% tax credit:

  • Credits on capital expenditures are partially refundable (up to 40%)
  • Credits on current expenditures remain fully refundable up to the expenditure limit

What Cannot Be Claimed

The following expenses do not qualify for SR&ED:

Excluded Costs

  • Administrative overhead not directly related to SR&ED
  • Sales and marketing expenses
  • Quality control for routine production
  • Training (unless directly related to SR&ED project)
  • Patent filing fees and legal costs
  • Routine software maintenance
  • Foreign contractor payments
  • Land and buildings (land is never eligible; buildings have specific rules)

Documentation Best Practices

To support your expense claims:

  1. Maintain contemporaneous records - Keep records as expenses occur
  2. Link expenses to projects - Show which SR&ED project each expense supports
  3. Keep invoices and receipts - Original documentation for all purchases
  4. Track time allocation - Document how employee time was split
  5. Photograph prototypes - Visual evidence of materials transformed
  6. Document disposal - Records of destroyed or scrapped materials
