John Yuan is a Toronto partner of McCarthy Tétrault’s National Tax Group. The focus of his practice is tax dispute resolution. He has extensive experience representing taxpayers at every stage of a dispute with tax authorities: audit, administrative objection, and litigation.
Much of John's tax law experience was gained earlier in his legal career in the transaction-implementation side of the firm's tax practice. This allowed him to develop a strong understanding of many of the tax concepts that are engaged when the tax authorities challenge the tax reporting of sophisticated clients. His previous tax dispute mandates have involved a broad range of industries, transaction types, and tax issues, including the following types of engagements:
- Assisting taxpayers with audits by tax authorities, including providing the taxpayer with support in responding to audit queries or formal demands for documents and information, and/or reassessment proposals and negotiating audit agreements
- Representing taxpayers in their administrative appeals of a reassessment
- Representing taxpayers in tax appeals before the Tax Court of Canada
- Representing taxpayers in applications for judicial review of an adverse decision by the Minister of National Revenue
- Assisting taxpayers with voluntary disclosure to the tax authorities of their historical unreported Canadian tax liabilities
- Advising on taxpayer compliance with Canadian income tax transfer pricing rules
- Advising on the application of the general anti-avoidance rule
- Advising taxpayers on their preparedness for being audited by tax authorities
- Assisting taxpayers with evaluating their uncertain tax positions and, where there is concern that the tax authorities will seek to challenge the taxpayer's tax filing position on a significant transaction, assisting the taxpayer with preserving relevant evidence and preparing contemporaneous documentation in respect of evidentiary matters in the event of a future tax dispute in respect of the transaction
- Assisting third parties with responding to tax authority demands for documents and/or information in respect of an unrelated person or group of persons
- Advising taxpayers and garnishees in tax collection matters
