Sales Tax, Indirect Tax, Commodity Tax Specialized Services

Why hire us, as a separate accountant, for your sales tax needs?

Sales tax in Canada is complex, constantly changing, and often misunderstood. We are a specialized Canadian sales tax advisory firm focused exclusively on GST/HST, PSTs, and RST matters. Unlike CPA accounting firms, sales tax is not a side offering for us — it is all what we do.


Canadian sales tax compliance is governed by a complex and highly technical legislative regime. At the federal level, the Excise Tax Act (the “ETA”) establishes the statutory framework for the Goods and Services Tax (“GST”) and Harmonized Sales Tax (“HST”), while provincial statutes govern retail sales taxes and related consumption taxes. This legislative framework is further shaped by the Canada Revenue Agency’s (“CRA”) administrative guidance, including GST/HST Memoranda Series, Technical Information Bulletins, Notices, Policy Statements, and evolving jurisprudence.

If the application of sales tax law were clear, mechanical, and self-explanatory, there would be little need for specialized technical or legal expertise. In practice, the opposite is true.

The ETA is a detailed and interpretive statute. Key concepts—such as commercial activity, supply, consideration, place of supply, input tax credits, exempt supplies, and zero-rated supplies—are defined broadly and applied through layers of interpretation. CRA publications, while informative, do not carry the force of law and frequently require careful reconciliation with the statutory text and applicable court decisions.

Moreover, CRA’s published positions are subject to change, qualification, and exception. What appears compliant on its face may not withstand scrutiny in an audit, objection, or appeal without a defensible legal and technical foundation.


Where Technical and Legal Expertise Matters

Our practice focuses on the interpretation and application of sales tax legislation in light of:

·       The statutory language of the Excise Tax Act and relevant provincial statutes

·       CRA administrative guidance and policy positions

·  Binding and persuasive court decisions from the Tax Court of Canada, Federal Court of Appeal, and Supreme Court of Canada

We analyze transactions not merely from a compliance perspective, but through a legal risk and defensibility lens. This approach allows us to identify overpaid tax, mitigate exposure, and support positions that are consistent with both the legislation and prevailing jurisprudence.


Beyond CRA Guidance — A Defensible Position

Many businesses rely exclusively on publicly available CRA publications or informal advice. While such materials are a useful starting point, they often do not address nuanced fact patterns or conflicting interpretations. Our role is to assess whether a particular position is:

·       Supported by the statutory framework

·       Consistent with or distinguishable from CRA’s administrative views

·       Defensible in the event of an audit, reassessment, or dispute

In numerous cases, the most advantageous outcome for a taxpayer lies in the interpretive margins of the legislation, where careful legal analysis can materially affect tax liability.


Practical, Strategic, and Results-Driven

We regularly assist clients with:

·       Sales tax exposure reviews and risk assessments

·       Recovery of overpaid GST/HST and provincial sales taxes

·       Audit support, voluntary disclosures, and dispute resolution

·       Transactional analysis and structuring from a sales tax perspective

Our objective is not merely to explain the law, but to apply it strategically, with precision and clarity, to protect our clients’ interests.
