FAQs
Common questions about C-Corp formation and tax filing for Canadian business owners.
What is the meaning of C-Corp?
A C-Corp is a US corporation the IRS taxes under Subchapter C of the Internal Revenue Code. That’s where the “C” comes from. The company exists as a separate legal entity and pays 21% federal corporate tax. Canadians choose C-Corps for US expansion since S-Corps are unavailable to us. Our c corp formation service guides you through everything.
What is the difference between C-Corp and S-Corp?
An S-Corp sends profits directly to shareholders and avoids corporate tax, but it only allows US citizens or permanent residents as shareholders. Canadians do not qualify. As a Canadian business owner, you can choose a C-Corp instead, and it often helps more when raising money from US investors.
Which is better for Canadians: LLC or C-Corp?
It depends on your goals. An LLC costs less and feels simpler, but CRA treats US LLCs as corporations, which often creates double taxation. If you plan to raise US investment or want clear treatment under the Canada–US Tax Treaty, you usually pick a C-Corp. If you have any other questions about LLCs, check here.
What is C-Corp double taxation?
Double taxation happens when a C-Corp pays corporate tax first and shareholders pay tax again on dividends. You can reduce or avoid it by reinvesting profits, paying yourself a reasonable salary, or using Canada–US tax treaty credits. But the best option is charging a reasonable management fee to your Canadian company.
What is the meaning of business incorporation?
Business incorporation creates a company that exists separately from you. Your C-Corp can own assets, signs contracts, hires employees, and takes legal responsibility. Incorporation gives you limited liability and protects your personal assets. We help with business incorporation in Ontario for your Canadian side and US C-Corps.

What is a business incorporation number?

What is a business incorporation certificate?
The state sends you a business incorporation certificate after approving your filing. This certificate proves your C-Corp legally exists and allows you to open bank accounts and work with vendors.
What is a business incorporation date?
The business incorporation date is the day the state approves your Articles of Incorporation. That date sets your company’s official start and begins your first tax year. For most calendar-year C-Corps, the tax year runs January 1 to December 31.
