Our Expertise

Smythe has one of Canada’s largest cross-border tax practices for an independent firm, consisting of three partners and more than 15 tax professionals.

Our professionals provide proactive US & cross-border tax solutions and compliance services for individuals and Canadian businesses planning, operating and expanding in and staging an exit from the United States. Services provided include personal tax returns, corporate tax returns, estate returns and tax disclosure requirements, among others.

What We Offer

Smythe will keep you up-to-date with current tax laws, regulations and procedures that could impact your cross-border personal and business compliance needs.

We believe in a “one firm, one team” approach, wherein we collaborate closely with our internal tax, assurance and accounting, and M&A teams. Our network extends to Canadian and US legal counsel, financial advisors, trade associations, banks and other financial institutions.

Our tailored services include:

Understanding the estate & gift tax system in the US can be complicated, with rules and requirements constantly changing. If you have lost a loved one or are planning, for future generations, our team can provide US estate tax solutions to minimize your tax exposure and navigate the gauntlet of reporting for your beneficiaries.

The cross-border reporting obligations for shareholders and investors of Canadian Private Companies, US S Corporations and US LLCs can be extremely complex and have punitive tax consequences. Our team at Smythe can help you navigate the tax rules while ensuring your business objectives are met.

If you are one of the hundreds of thousands of people relocating from Canada to the US, or vice versa, our consultants are experts in tax issues you must consider. This involves reviewing investments, reporting obligations and potential “traps” resulting from the network of laws between the two countries. Leaving this aspect of your move to us may free you up to focus on other pressing concerns.

Purchasing real estate is one of life’s most significant milestones, but can also be a source of worry if it involves cross-border taxation and reporting. We can provide you with both technical and practical input to ensure you are fully compliant with laws in both the US and Canada when you decide to take this step.

Our team can assist if you have stock options, RSUs or other stock plan income earned inside and outside of Canada. We have significant experience assisting employees with correctly reporting their stock income and reconciling what has been reported via payroll.

We have in-depth and direct experience with how businesses operate in the US and within a multi-state environment, whether that be small to mid-size enterprises or multi-national corporations.  

We work in tandem with our Canadian and international tax teams to help develop strategies that maximize after-tax returns on investments for Canadian owners and shareholders.

From setting up a US subsidiary C Corporation to investing in US Limited Partnerships, we help Canadian corporations and investors maximize their footprint while planning efficient and risk-mitigated repatriation strategies for funds coming back to Canada.

We assist Canadian corporations and investors in navigating the US tax system when purchasing, operating and selling commercial real estate. Our expertise includes like-kind exchanges and cost segregation analysis and reporting.

We are adept in developing multifaceted tax strategies geared towards collaboration between Canadians and Americans on business ventures. Every business has a unique blueprint within a cross-border landscape, which necessitates specific and customized tax strategies to maximize return for parties on both sides of the border.

Working in tandem with our internal Canadian and international tax groups, we can help structure and plan investments of US businesses or individuals interested in looking at Canada.
