US citizens in Canada face double tax trouble. In particular, US taxpayers with Canadian corporations (such as incorporated professionals and business owners) face the daunting challenge of two competing tax systems. We’ve helped hundreds of business owners navigate this complexity. Specifically, we can: 

• Help US citizen professionals such as doctors, dentists, and lawyers incorporate their practices to achieve meaningful tax deferral and savings; 
• Assist business owners with a variety of corporate re-organizations to achieve tax savings and accomplish other business and legal goals;
• Clarify the US tax reporting obligations faced by US citizen business owners; 

We have written a number of blog posts and technical articles in this area as well. Recently, Max Reed gave a presentation on using a corporation as a US citizen. You can view the slides here.
