If you live in Canada, the CRA taxes you on your income from everywhere, so a cross border accountant’s first job is to get foreign income onto the return correctly. Another country may tax the same money, and Canada’s answer to that is the foreign tax credit, claimed on Form T2209.
What does a cross border accountant do?
Cross border work covers people and companies whose money touches two countries. That could be a Canadian with a rental in another country, a person who moved to or from Canada during the year, or a business selling across the border. The accountant has to know both tax systems, or work with a partner who does.
That’s rarer than the ads suggest. Plenty of firms list “international tax” as a service, and some just mean they’ve seen a foreign slip before. We can’t rank firms, and there’s no official figure for what this work costs, so you won’t find either here. What we can do is show you what the Canadian side looks like and what to ask.
What does foreign income do to your Canadian tax?
It adds to your income, and it’s taxed at your top rates. Take an Ontario resident with $85,000 of employment income. The income tax calculator shows $15,551 of tax for 2026. Add $10,000 of other taxable income, such as foreign rent, and the tax becomes $18,516. The extra $10,000 costs $2,965 before any credit for tax paid abroad.
Think of that figure as the ballpark ceiling for this example. If the other country already took tax on the $10,000, the foreign tax credit can offset part of the Canadian tax on it. Say, for illustration, that $1,500 was paid abroad and the whole amount qualified: the extra Canadian tax would drop from $2,965 to $1,465. Real files rarely come out that tidy, because the credit has its own limits.
The CRA’s page on the federal foreign tax credit says foreign income and foreign taxes must be converted to Canadian dollars, using the Bank of Canada exchange rate on the day the amounts arose, and that a tax treaty can change whether you qualify. The marginal tax rate calculator shows how much tax the next dollar adds at your income.
Which foreign property must be reported?
Income from foreign property goes on your return at any cost level. Separately, if the total cost of your specified foreign property passes $100,000 at any time in the year, Form T1135 is also required. The CRA describes a simpler section for property that stayed under $250,000 and a detailed one from $250,000. Penalties exist for late or false filing. Confirm current thresholds on the form itself, since we read them from the CRA’s summary pages.
| Situation | What the CRA asks for |
|---|---|
| Foreign income, any amount | Report it on your Canadian return, in Canadian dollars |
| Foreign tax already paid | Possible foreign tax credit, Form T2209 |
| Foreign property costing over $100,000 | Form T1135, simplified section if under $250,000 |
| Foreign property costing $250,000 or more | Form T1135, detailed section |
Who should you hire for cross border tax?
Someone who has done your exact situation this year, whatever label is on the door. Ask these:
- Which countries’ returns do you prepare, and which do you refer out?
- Have you filed a T1135 and a T2209 for a client like me?
- Who handles the other country’s return, and how do you two coordinate?
- What is your fee for the Canadian part alone?
An answer of “we do it all” needs a follow-up. Ask who signs the foreign return and whether they’re licensed there.
What should you gather before the first meeting?
Bring every foreign slip and statement, even the dull ones, and the foreign tax return if one was filed. Add a list of foreign accounts and property with what each cost you and when, plus proof of the tax paid abroad. If you moved countries during the year, bring the dates: the day you left, the day you arrived, and where your home and family were.
Someone in Windsor who owns a cottage across the river in Michigan has a very different pile from a software contractor paid by a company in Texas. The more clearly you describe your pile, the less time you pay for.
What goes wrong with foreign income?
People forget small foreign accounts, so a dividend from an overseas brokerage never reaches the return. They use the wrong exchange rate, or one day’s rate for the whole year. They also assume a treaty means no tax, when it usually means a limit or a credit. And they file the foreign side first without looking at the Canadian one, which is how a credit gets missed.
Business owners face more. A corporation with foreign customers still files its T2 in Canada, and the corporate tax calculator shows the domestic tax for a Canadian-controlled private corporation. Sales tax rules across borders are a separate topic we haven’t verified here.
Where we got these figures
Worldwide income, the foreign tax credit and the T1135 thresholds come from the Canada Revenue Agency‘s pages on the foreign tax credit and foreign income verification statement, read in September 2026. The tax example comes from this site’s income tax calculator using 2026 federal and Ontario data. This is an independent guide, separate from any government body.
