Cross-Border and Non-Resident Tax — Your Canadian Obligations, Handled Correctly

Foreign income, foreign property, moving to or leaving Canada, or earning Canadian income as a non-resident — Trim Tax prepares your Canadian filings, applies the Canada–US Tax Treaty and Canada's other tax treaties correctly, and makes sure nothing is double-taxed or missed.

When your tax life crosses a border

Canada taxes its residents on worldwide income and taxes non-residents only on certain Canadian-source income. That single rule creates most cross-border complexity: a Canadian resident must report a foreign rental, a foreign pension and a foreign brokerage account; a newcomer must report world income only from the date of arrival; an emigrant faces a deemed sale of most assets on departure; and a non-resident landlord must deal with 25% withholding on Canadian rent.

Each situation has its own forms, elections and deadlines, and the penalties for missing a reporting form can exceed the tax involved.

Trim Tax focuses on the Canadian side of every cross-border situation. We determine your residency, report foreign income and assets, claim foreign tax credits, handle emigration and immigration, and manage non-resident withholding and returns.

Where you also have a filing obligation in another country — a US return, for example — we work alongside your foreign tax preparer, sharing figures and timing so credits and elections line up on both returns. We do not prepare US or other foreign returns ourselves, and we tell you so at the start.

Residency is the first question — and the most expensive to get wrong

Whether you are a factual resident, a deemed resident, a deemed non-resident under a treaty tie-breaker rule, or a non-resident earning Canadian income determines which returns you file, which elections apply and how much tax you pay.

The CRA looks at significant residential ties (a home in Canada, a spouse or common-law partner, dependants), secondary ties (vehicles, bank accounts, provincial health coverage, memberships) and days of presence, including the 183-day sojourning rule for people who spend long periods in Canada. Before preparing anything, we document your ties, days and treaty position in writing, so the rest of the plan rests on solid ground and your file can be defended if the CRA asks.

Frequently asked questions

Yes. Canadian residents report worldwide income, converted to Canadian dollars. Where the other country has already taxed that income, a foreign tax credit usually prevents double taxation, and a tax treaty may exempt certain amounts entirely. We calculate the credit and apply the treaty correctly on your Canadian return.
The Foreign Income Verification Statement, required when the total cost of your specified foreign property — foreign bank accounts, shares of foreign companies, foreign real estate other than personal-use property, and certain other assets — exceeds C$100,000 at any time in the year. Penalties for non-filing are $25 per day up to $2,500 per year, and more where the failure is knowing or grossly negligent, even when no tax is owed.
On the date you cease Canadian residency you are deemed to have sold most capital property at fair market value, and the resulting gain is taxable on your final return. Canadian real estate, RRSPs and certain other property are excluded. We calculate the gain, file T1161 and T1243, and consider the T1244 election to defer payment by providing security.
Yes, with your Canadian filings. We prepare your Canadian return and provide the figures your US preparer needs, such as foreign tax paid and income by source. We do not prepare US returns. Because the US may treat some Canadian accounts, such as TFSAs and RESPs, differently, speak with your US preparer before opening them.
The CRA treats an LLC as a corporation, while the IRS may treat it as a flow-through entity. The mismatch can leave income taxed in the US without a matching Canadian foreign tax credit, or taxed twice on distribution. We review the Canadian treatment and reporting and coordinate with your US advisor on alternatives.
Your Canadian agent or tenant must withhold 25% of gross rents and remit it monthly unless an NR6 undertaking is approved, in which case withholding applies to net rent. A Section 216 return filed after year-end reports actual net income and usually generates a refund of excess withholding.
A part-year return reporting world income from your date of arrival (and Canadian-source income before it), with your assets stepped up to fair market value on arrival. You should also apply for the Canada Child Benefit and GST/HST credit using RC66 or RC151. We prepare the return and the applications together.
