About Us
About the Firm
Tax Square Professional Corporation provides Canadian, US, and Canada-US cross-border tax and accounting services. The firm supports individuals, entrepreneurs, owner-managed companies, and organizations with filing obligations or business activity on both sides of the border.
Our work begins with understanding the full structure of a client’s affairs. We then identify the relevant Canadian and US requirements, explain the available options, and establish a practical plan for compliance and future decisions.
Professional Leadership
Tax Square is led by Adnan Khan, a Certified Public Accountant licensed in Colorado, a Chartered Professional Accountant in Canada, and a Fellow of the Association of Chartered Certified Accountants. His background includes cross-border taxation, accounting, business advisory, and more than ten years of accounting education in Canada.
