Taxation can be the most complicated and stressful part of your international move. We are experts in income tax and estate-planning issues faced by individual Canadian and American expatriates living in their neighbouring country. A US Canada tax preparation expert will guide you through the minefield of double taxation and ensure you only pay what you are legally required.

We offer corporate tax services to businesses opening cross-border branches or filing tax returns for expat employees. We also consult businesses considering doing business in the U.S. or Canada. These services include tax planning and advice on incorporation and entity structure for corporations, partnerships and sole proprietorships transitioning from one country to another.


We also provide confidential services to lawyers, accounting firms, and other financial professionals who can benefit from our international tax expertise. Our accountants understand the interaction of the Canada U.S. Tax Treaty with domestic tax rules. Our services include compliance and research either through your firm, or directly to your client.
