If I were in your situation, at the start I probably would have looked into having the Canadian entity contract with the US entity for services, so that the US entity is the one paying you personally (but that also may involve registering the US entity in Canada).

The tax season has now started for accountants, it being January, so it is desirable to talk to and engage someone quite soon before they are too busy with their existing clients to deal with you.

Thank you for your tips. Can I retroactively subcontract (the books) canadian --> US? That makes a lot of sense, otherwise I think I'm facing a double taxation problem.

A question to get an answer to from your new professional advisor, is, can you reasonably and legitimately treat those payments as personal loans or advances (if paid to you and not paid to third parties), pay these loans back at this point to the Canadian entity, and belatedly contract between Canadian/US entities for services rendered.

You're a couple of years late on getting good advice on business entity structures and relationships...since you've been operating for a while now.
