Do you own a US LLC, a US C-corp, or any non-resident company with at least 10% equity?
If yes, you have a Form T1134 filing obligation in Canada. The form reports the foreign affiliate's existence, control structure, and financials — but does not assess any tax of its own.
The catch: a US LLC is treated as a corporation under Canadian tax law (the CRA doesn't recognize US "disregarded entity" status), so single-member US LLC owners are caught from day one. Filing deadline is 10 months after year-end — much earlier than the regular tax returns.
Late filing penalties start at $25/day capped at $2,500, escalate to $12,000 for gross negligence, and can reach 5% of the affiliate's cost amount after 24 months of non-compliance.
