How it works

WHAT IS THE OMMITC?

The Ontario manufacturing tax credit, officially known as the Ontario Made Manufacturing Investment Tax Credit (OMMITC), encourages businesses to engage in manufacturing activities in Ontario by providing a tax credit on their eligible expenditures.

For eligible investments made after May 14, 2025, and before 2030, it offers a 15% refundable tax credit on eligible investments (previously 10%), up to a maximum of $3 million per year based on an investment limit of $20 million (shared among an associated group). Corporations other than CCPCs are now eligible for this period, receiving a non-refundable credit that can be carried forward for up to 10 years.

The OMMITC supports corporations that:

  • Are a CCPC (refundable credit) or, for investments made after May 14, 2025, and before 2030, a corporation other than a CCPC (non-refundable credit)

  • Carry on a manufacturing business in Ontario

  • Own or lease a permanent establishment in Ontario (e.g., an office, factory, warehouse, or through the use of substantial equipment)

  • Are not exempt from Ontario corporate income tax for the relevant tax year
