US-Canada Cross-Border Tax Planning
Proactive treaty optimization, entity structuring, compensation planning, and dual-jurisdiction strategy for individuals and businesses with ongoing US-Canada exposure. TYM's cross-border tax planning practice is built for those who need more than annual compliance — they need a strategy.
Cross-border tax planning is not a one-time exercise. The US-Canada Tax Treaty provides significant planning opportunities — reduced withholding rates, tie-breaker rules, pension provisions, and entity structure elections — but these benefits must be actively claimed and maintained. TYM provides annual planning reviews to keep the tax position optimized as circumstances change.
What US-Canada Tax Planning Covers
Effective cross-border tax planning addresses the full range of US-Canada tax interactions — from compensation structure and entity design to investment accounts and real estate. Each planning area has specific treaty provisions, elections, and timing considerations.
Treaty-Based Compensation Planning
For individuals with income from both Canada and the US, the allocation of compensation between jurisdictions — and the use of treaty tie-breaker rules — can significantly affect the overall tax burden. TYM structures compensation arrangements to optimize treaty benefits while maintaining compliance with both CRA and IRS requirements.
Entity Structure Optimization
The choice of entity — Canadian corporation, US LLC, C-Corp, ULC (Unlimited Liability Company), or hybrid structure — has significant cross-border tax implications. TYM analyzes the treaty treatment of each structure, the branch profits tax, and the interaction between Canadian and US corporate tax rates to recommend the optimal structure for your specific situation.
Investment Account Planning
The tax treatment of Canadian investment accounts — RRSPs, TFSAs, RESPs, RRIFs — differs significantly between Canada and the US. TYM advises on the optimal account structure for US persons in Canada, including RRSP treaty elections, TFSA reporting obligations, and the interaction between Canadian registered accounts and US retirement account rules.
Real Estate Structuring
Canadians owning US real estate, and US persons owning Canadian real estate, face specific structuring decisions that affect FIRPTA withholding, capital gains tax, rental income treatment, and estate tax exposure. TYM advises on holding structure, financing, and exit planning for cross-border real estate.
Retirement Income Planning
The treaty treatment of Canadian pensions (CPP, OAS, employer pensions) and US retirement income (Social Security, 401(k), IRA) for cross-border individuals requires careful planning. TYM advises on the treaty articles governing pension income, the optimal timing of withdrawals, and the interaction between Canadian and US retirement income systems.
Pre-Move Planning
Planning before a cross-border move — whether from Canada to the US or from the US to Canada — can significantly reduce the tax cost of the transition. TYM advises on the optimal timing of asset dispositions, RRSP contributions, and entity restructuring before departure or arrival.

FAQ: US-Canada Tax Planning
What is the US-Canada Tax Treaty and how does it affect planning?
The Convention Between Canada and the United States of America with Respect to Taxes on Income and on Capital (1980, as amended) is the primary framework governing cross-border taxation between the two countries. The Treaty provides reduced withholding rates on dividends, interest, and royalties; tie-breaker rules for dual residents; pension income provisions; and rules for business profits and employment income. Proactive planning uses Treaty provisions to minimize double taxation and optimize the overall tax position.
What is the 183-day rule and how does it affect cross-border workers?
Article XV of the US-Canada Tax Treaty provides that employment income earned in one country by a resident of the other country is exempt from tax in the source country if: (1) the employee is present in the source country for fewer than 183 days in any 12-month period; (2) the remuneration is paid by an employer who is not a resident of the source country; and (3) the remuneration is not borne by a permanent establishment in the source country. This provision is frequently relevant for cross-border employees and contractors.
What is a ULC and why is it used in cross-border structures?
A ULC (Unlimited Liability Company) is a Canadian corporate entity available in Alberta, British Columbia, and Nova Scotia. Unlike a standard Canadian corporation, a ULC is treated as a flow-through entity (disregarded entity or partnership) for US tax purposes under the check-the-box rules. This allows a US parent to consolidate Canadian ULC income on its US return while maintaining Canadian corporate status. ULCs are commonly used in US-Canada cross-border structures to achieve flow-through treatment for US tax purposes.
How does the treaty treat RRSP and TFSA for US persons?
The US-Canada Tax Treaty (Article XVIII, paragraph 7) allows US persons to defer US tax on RRSP income until withdrawal — matching the Canadian treatment — but only if a treaty election is made on Form 8833. Without the election, RRSP investment income is taxable in the US as it accrues. TFSAs are not recognized as tax-exempt by the IRS; income earned inside a TFSA is taxable in the US in the year earned, and TFSAs may have Form 3520 reporting obligations.
When should I start planning for a cross-border move?
Planning should begin at least 6–12 months before a planned move. For a move from Canada to the US, this allows time to optimize the timing of RRSP contributions, asset dispositions, and departure tax planning. For a move from the US to Canada, this allows time to optimize the timing of IRA/401(k) distributions, US asset dispositions, and Canadian arrival planning. Retroactive planning after the move is significantly more expensive and less effective.
