Canadians love US investments, and it’s easy to see why. Deeper markets, iconic companies, and easy access through any Canadian brokerage account make it tempting to just buy and hold.
But here’s what most investors don’t realize until it’s too late: cross-border tax rules can quietly erode your returns long before your accountant ever spots the problem. US withholding taxes, PFIC traps on US ETFs, and estate tax exposure don’t wait for tax season, they start working against you the moment your money crosses the border.
At Real File CPA, our team holds both Canadian and US professional designations, which means we see both sides of the border simultaneously and not after the fact, when the damage is already done.
Here are five pitfalls we help clients fix every day.
1. Withholding Tax on US Dividends
If your accounts aren’t structured correctly, the IRS can withhold as much as 30% on US dividend income. Most Canadian investors assume the treaty rate automatically applies, but the wrong account type or missing paperwork can mean you’re leaving real money on the table with every dividend payment.
2. PFIC Rules Turning US Mutual Funds Into a Tax Nightmare
Canadians investing in US mutual funds (and some ETFs) can unknowingly trigger Passive Foreign Investment Company (PFIC) rules. The reporting is complex, the penalties for getting it wrong are steep, and the tax treatment is often far worse than investors expect. This is one of the most common, and most costly, surprises we see.
3. US Estate Tax Exposure Starting at Just $60,000 USD
Many Canadians are stunned to learn that the US estate tax can apply to non-residents holding as little as $60,000 USD in US situs assets. Stocks, real estate, and other US-based holdings can all count, meaning even a modest US investment portfolio may carry estate tax exposure your family isn’t prepared for.
4. Foreign Reporting Obligations on T1135 and FBAR
Holding US investments often triggers reporting obligations on both sides of the border; the T1135 for the CRA and the FBAR for the IRS. Missing or misfiling these forms can lead to significant penalties, even when no tax is actually owed.
5. RRSP/TFSA Treatment of US-Listed Securities
Not all registered accounts are treated equally by the IRS. US-listed securities held inside an RRSP get different treatment than those held in a TFSA, and getting this wrong can mean losing tax-sheltered status or facing unexpected US tax consequences.
Don’t Let a Great Investment Become a Tax Problem
Cross-border investing can be incredibly rewarding, but only if it’s structured correctly from the start. With the right guidance, these five pitfalls are entirely avoidable.
