International Tax Accountants

Are you looking for an international tax accountant to help with US - Canada or Canada - US tax preparation?

Serbinski Accounting Firms specialize in Canadian and American cross-border taxation. As a cross border tax accounting firm, we bring over 30 years of international tax expertise to our clients in Canada and the U.S. With offices in Toronto and Chicago, we are ideally poised to help clients on either side of the border, and are ready to represent you in all states and provinces.

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 neighboring 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.
