Crossing the 49th Podcast Crossing the 49th — Cross-Border Tax & Financial Planning Podcast
If you’re an American living in Canada, you’ve probably heard the advice: “Just file your Canadian return first, then do your US return.” In a lot of cases, that works. But if you have investment income, US rental properties, or US-source dividends, filing in the wrong order can cost you thousands — and trigger a CRA review you didn’t see coming.
In this episode, Phil Hogan breaks down exactly when filing your Canadian return first works, when it doesn’t, and why the foreign tax credit calculation is where most people get burned.
If your tax situation is straightforward — you’re employed in Canada, you have a T4, and no investments — filing the Canadian return first is perfectly fine. You report your Canadian employment income, file the return, then hand everything to your US preparer.
On the US side, your preparer reports the T4 income on the 1040 and either claims a foreign tax credit for Canadian taxes paid, or uses the Form 2555 Foreign Earned Income Exclusion to wipe out the US tax. Two options, both work well for simple returns.
If you only have Canadian employment income (T4) and no investments, rental income, or US-source income, you can safely file your Canadian return first and your US return second. The foreign tax credit math is straightforward.
Here’s where it gets tricky. Let’s say you’re an American living in Canada with:
If you file the Canadian return first, you’d report your worldwide income — employment, rental income, capital gains, interest, and dividends. Then you’d need to claim a foreign tax credit for US taxes paid on that US-source income.
But here’s the problem: how do you know what your US taxes are if you haven’t filed your US return yet?
Many people claim a foreign tax credit based on the withholding tax shown on their slips (often 15%, the treaty rate). But your actual US tax on that income may be less than 15% — especially if you’re not in a high income bracket. And for US rental income, you have no idea what the tax will be until the 1040 is prepared. Filing the Canadian return with incorrect foreign tax credits is one of the most common cross-border mistakes.
This is the part most people don’t see coming. After you file your Canadian return, the CRA frequently sends a review letter asking you to prove your foreign tax credit calculation.
They’ll ask for:
If the amount of US tax you actually paid on your 1040 doesn’t match what you claimed as a credit on your Canadian return, the CRA will reassess you. If you overstated your foreign tax credit, you’ll get a bill for the difference — plus interest.
The CRA knows that foreign tax credit claims are frequently wrong. That’s why they audit them regularly. The root cause is almost always the same: the Canadian return was filed before the US return was complete, so the foreign tax credit was based on estimates or withholding amounts instead of actual US tax paid.
The solution isn’t necessarily that the same person does both returns — although that’s ideal. The key is: do not file your Canadian return before your US return is at least started or in process.
When both returns are prepared together, the preparer can:
In Phil’s experience, when a Canadian preparer does the T1 and a separate US preparer does the 1040, you often end up with weeks of back-and-forth — emails, phone calls, revised calculations — all of which is completely avoidable if the returns are prepared under one roof.
Even if both preparers are competent, the coordination overhead is real. Weeks of going back and forth on foreign tax credit calculations by email is an inefficient and error-prone way to handle cross-border returns. One firm handling both sides eliminates this entirely.
“File your Canadian return first, then your US return” is advice that works for simple situations — and fails for everything else. If you have investment income, US rental properties, US dividends, or any US-source income, your Canadian and US returns need to be prepared together, or at minimum, in close coordination.
The foreign tax credit is the linchpin of cross-border tax filing. Get it wrong, and you’re looking at CRA reassessments, interest charges, and a lot of unnecessary stress. Get it right by filing both returns in tandem — ideally under one roof.
