About Us

Rosen Kirshen Tax Law

Rosen Kirshen Tax Law is a national tax law firm based in Toronto, Ontario. We take a proactive, client focused approach allowing our lawyers to provide comprehensive legal tax advice and representation.

Our focus and expertise is centered around the complex area of tax law placing Rosen Kirshen Tax Law (“RKTL”) in a unique position to deliver the quality of service and legal tax defense rightfully expected by hardworking Canadians.

We provide tax advice to domestic and international clients alike. Our practice encompasses all aspects of taxation including tax planning and restructuring, tax litigation at all court levels, and advice on compliance obligations.

The Canada Revenue Agency (“CRA”) can be an intimidating organization – especially considering their interests are not necessarily aligned with those of taxpayers. The CRA has established administrative policies and procedures that guide their enforcement actions. These policies and procedures tend to differ from the jurisprudence of the Tax Court of Canada. RKTL exists solely to defend the rights and uphold the interests of hardworking Canadian taxpayers against the often heavy-handed actions of the CRA.

If you find yourself in a tax dispute with the CRA, whether it be an unfair tax reassessment, bank seizure or tax lien, or fear Revenue Canada may pursue you for unreported income, consult a tax lawyer at RKTL today and explore your options.

Free legal consultations with a tax lawyer are offered in most cases.

Please contact us if you have any questions concerning the firm or want to explore the available avenues.
