Frequently Asked Questions
Quick answers to the questions founders most often ask about Ontario Innovation Tax Credit
Free
Can sole proprietors apply for OITC?
No — only incorporated Canadian corporations with a permanent Ontario establishment qualify. Sole proprietors, partnerships, and trusts are ineligible for OITC. Must file T661 and Schedule 566 within 18 months of fiscal year-end.
What's the realistic OITC payout for startups?
Startups with <$500K prior-year income and $500K–$1.5M in Ontario R&D payroll typically recover $40,000–$120,000 as a cash refund. Most SMEs claim $30,000–$120,000 annually.
When must I file T661 for OITC?
T661 and Schedule 566 must be filed within 18 months of your fiscal year-end. Missing this deadline permanently forfeits the credit — no extensions or appeals are possible.
Why do OITC claims get rejected?
Common rejections: missing the 18-month T661 deadline, claiming ineligible expenses (routine testing, admin), or failing to separate Ontario-attributable costs from out-of-province operations.
Can I stack OITC with SR&ED?
Yes — OITC is stackable with federal SR&ED ITC, but OITC reduces the SR&ED qualified expenditure base. Must calculate OITC before claiming federal SR&ED.
