Tax Disputes

When winning in a tax dispute means everything to your business, you need the best legal advice available. You need McCarthy Tétrault.

Domestic and international corporations, including financial institutions, resource companies and manufacturers, as well as high net-worth individuals, count on us to defend them in Canada's progressively hardening tax environment. 

Today, Canadian tax authorities aggressively challenge a wide range of transactions. General anti-avoidance rules support increasingly complex legislation and detailed technical requirements.

We help you resolve disputes in the most timely and favourable way possible because: 

  • We have a proven track record. As Canada's pre-eminent litigation firm for over 150 years, we have litigated some of the largest taxation cases in the country. 
  • We advise you on your chances of success. Our experience encompasses every kind of tax dispute and all dispute resolution techniques, from the audit or pre-assessment stage to the courts.
  • We understand your business. Our top-ranked practitioners bring keen knowledge of your interests to team with your in-house tax and legal staff, as well as with your auditors and other outside advisors.
  • We understand the challenges from the inside out. Many of our lawyers have developed inside knowledge working within the Department of Justice, the Rulings Directorate of the Canada Revenue Agency, the Department of Finance and the Tax Court. The tax authorities know us and know we aim to win.
  • We have an expert team. Through our offices across Canada, some of this country’s most successful and experienced tax lawyers work closely on your behalf with the strongest civil litigators in the nation. Our tax litigators partner seamlessly with our tax planning specialists in corporate tax, commodity/customs tax, personal tax and cross-border taxation to formulate the most powerful arguments in support of your position.

We protect your rights at every stage of controversy:

  • Planning – We address strategic issues in your tax planning process so you can avoid potential tax assessments.
  • Audit – We guide you through the proper conduct of an audit by tax authorities and can challenge excessive practices through judicial review. 
  • Appeal – We prepare a well-researched and powerfully-expressed notice of objection.
  • Litigation – We represent you before all levels of Canada’s federal and provincial courts, including the Tax Court of Canada.
