For the purpose of providing an example to our readers, we have addressed the Ontario SR&ED Tax Credits. As addressed above, in Ontario there is a limit on the Ontario Innovation Tax Credit (OITC) but none on the Ontario Research and Development Tax Credit (ORDTC).
Example: Ontario Maximum SR&ED Refund
The province of Ontario’s SR&ED tax credit programs include a refundable credit of 8% and a non-refundable credit of 3.5%. Non-refundable tax credits still count towards the claimants total SR&ED refund even though they can only be applied to reduce the taxpayers Part 1 tax owing for the tax year or be carried over to other years for the same purpose.
OITC: Refund Restrictions
The limit placed on the refundable OITC program involves the application of an overall expenditure limit:
Based on an expenditure limit of $3 million:
- for taxation years that commence after May 31, 2016, the maximum tax credit amount is $240,000
- the maximum tax credit amount is prorated for taxation years straddling June 1, 2016, and
- for taxation years that end before June 1, 2016, the maximum tax credit amount is $300,000.
The expenditure limit is gradually reduced if:
- federal taxable income of the prior tax year exceeds $500,000 and is totally eliminated at $800,000, or
- the prior year’s taxable capital exceeds $25 million and is totally eliminated at $50 million. 1
OITC: Running the Numbers
The Ontario provincial eligible expenditure limit is $3M. This means at the OITC rate of 8%, $240,000 is the maximum refund of OITC ITCs available to any claimant per tax year:

- In the example above, Line 707 shows the eligible expenditure limit ($3M) has been applied.
- The OITC ITCs calculate in Line 712 as 8% of $3,000,000 = $240,000
Be sure to review your provincial or territorial SR&ED rules before filing your SR&ED Claim.
ORDTC: No Refund Restrictions
The non-refundable ORDTC program does not have an expenditure limit imposed on it, an therefore the entirety of the claimants eligible expenditures is used to calculate these credits. The CRA describes the Ontario research and development tax credit (ORDTC) as:
It is a non-refundable tax credit based on eligible expenditures incurred by a corporation in a tax year.
The ORDTC rate is:
- 4.5% for tax years that end before June 1, 2016
- 3.5% for tax years that start after May 31, 2016
- prorated for a tax year that ends on or after June 1, 2016, and includes May 31, 2016.2
ORDTC: Running the Numbers
The ORDTC program, which has a rate of 3.5%, does not have an expenditure limit imposed on it. This means there is no maximum refund of ORDTC ITCs available to any claimant per tax year:

- In the example above, the calculation resulting in the amount on Line 202 shows there is no expenditure limit applied.
- The ORDTC ITCs calculate in Line 232 as 3.5% of the total eligible expenditures, which in this case is $4,410,000. The total ORDTC amount in this case is $154,350.
Be sure to review your provincial or territorial SR&ED rules before filing your SR&ED Claim.
