David Smith, CMA
David Smith’s career in commodity taxation started in 1986 with The Ontario Ministry of Finance. During three years with Finance, David held various positions in the Sales Tax Refunds and Audit Groups of The Retail Sales Tax Branch. In 1989, David left Finance to join one of Canada’s largest newspaper and business communication companies as a commodity tax specialist. Providing support to business groups across Canada, his extensive experience in dealing with government authorities and tax legislation ensured this organization maintained a high level of compliance while minimizing sales tax expenses.

Prior to forming Smith Thimm & Associates, David was employed by a sales tax consulting firm where he focused on identifying sales tax refund opportunities. He completed tax reviews for hundreds of organizations including many of North America’s largest companies and recovered millions of dollars of sales tax overpayments.
