U.S. passport, Toronto mortgage? Lucky you: two tax seasons, every spring, for as long as you hold that passport. Canada wants a return because you’re resident here, and it taxes your income from anywhere in the world. The U.S. wants one too, purely because you’re a citizen, and it’s looking at that exact same income, Toronto address or not. Foreign tax credits usually mean the U.S. bill ends up at zero, but the filings still have to happen, every year, without exception. Once you understand how the yearly cycle runs, it gets a lot less stressful, and much harder to mess up.
What follows is the annual routine for U.S. citizens and green card holders in Canada who are already up to date. Behind on U.S. filings? That’s a separate project with its own steps, and it isn’t covered here.
The T1’s due April 30. If you or your spouse run a business, the paperwork gets until June 15, though any balance still has to be paid by April 30. It reports everything you earned anywhere, U.S. income too; for U.S.-source income, part of the U.S. tax you paid usually comes back to you as a Canadian credit.

The IRS circles April 15. If you’re living outside the country on that date, you get an automatic bump to June 15, and Form 4868 buys you until October 15. Don’t confuse that with extra time to pay. Interest on anything you owe is counted from April 15 regardless.
Most cross-border preparers do the Canadian return first, or the two side by side, since the U.S. return needs the Canadian tax numbers to work out foreign tax credits.
Two main tools keep the same income from being taxed twice:
Give the first-year choice some real thought, because you’ll be living with it after that.
Take the highest balance each non-U.S. account hit during the year and add them up. Did the total ever go past US$10,000, even for a day? Then you’re filing an FBAR. Chequing and savings, investment accounts, your RRSP and TFSA all count, and so does your mom’s account if you’ve got signing authority on it to help her pay bills. It’s not part of the tax return at all. It goes to FinCEN electronically, due April 15 with an automatic extension to October 15, and forgetting it can bring stiff penalties even in a year you owed the IRS nothing.
Then there’s 8938, which people constantly mix up with the FBAR. It reports specified foreign financial assets, but only past higher thresholds, which are more generous for citizens living abroad than for those at home and depend on your filing status. This one rides along with your 1040. There’s often overlap with the FBAR, but filing one doesn’t excuse you from the other.
RRSPs and RRIFs are the friendly ones. The treaty lets U.S. citizens put off U.S. tax on the income growing inside them until money comes out, and for eligible people that deferral happens automatically now, no election needed. The accounts still go on the FBAR.
The U.S. doesn’t recognize the TFSA’s tax-free status. Income earned inside one is generally taxable on your U.S. return, and some practitioners think extra trust reporting may apply on top. Plenty of U.S. citizens in Canada decide a TFSA isn’t worth the added cost and hassle.
RESPs have similar problems. Income inside isn’t sheltered from U.S. tax, and government grants may be treated as taxable. So before the first deposit, it’s worth a conversation about whose name the plan should be in.
Here’s the trap people fall into most. The Canadian index ETF or balanced fund your bank’s adviser loves? In the IRS’s eyes it’s likely a PFIC (passive foreign investment company), and PFICs come with harsh default tax rules and a Form 8621 apiece, annually. Cross-border advisers often nudge clients toward individual stocks instead, or U.S.-listed funds where those make sense.
Big life moves change the U.S. side, often in ways people don’t see coming. Sell the house, start a business, inherit, marry a non-American, have a baby. Take the house sale: your principal residence may be entirely tax-free in Canada and still leave you with a taxable U.S. gain once you’re past the U.S. exclusion amount. Own a Canadian corporation as a U.S. citizen and extra U.S. information returns follow. Before any big financial decision, ask how it’ll look on both returns.
Lots of families find that an annual review with cross border tax services in Toronto or wherever they live keeps both returns in sync more easily than two separate preparers working from different assumptions.
As a U.S. citizen in Canada you’ll file two returns, report foreign accounts, and find that some Canadian investments don’t travel well across the border. Actual double tax, though? Rare. Plan the year around the key dates. Use the foreign tax credit. File the FBAR every single year. And stop to think before you open a TFSA or buy Canadian mutual funds. Get it right the first time and after that it’s mostly habit.
If income is over the U.S. filing threshold, yes, and that’s true even in years when foreign tax credits leave nothing to pay.
Yes. It’s a foreign financial account as far as the FBAR is concerned, treaty deferral or not.
The IRS doesn’t see it that way. TFSA income is generally taxable on your U.S. return, and extra reporting may be needed.
They’re usually PFICs, which means complicated reporting and unfavourable default tax treatment in the U.S.
June 15 if you live abroad, automatically, with October 15 available on extension. Interest on unpaid tax still dates from April 15.
