Posted By You did everything right for retirement in Canada. Then you started spending winters down south, and a different rulebook quietly took over.

Ask a Canadian snowbird how many days they can spend in the U.S. before things get complicated, and most give the same answer: 182. Stay under half the year and you’re fine. That number is comforting. It’s also the wrong number, and trusting it is how careful savers walk into problems they never saw coming.
Over the past year I’ve talked with a lot of Canadians who split their time across the border, and the same five traps catch them again and again. Here they are:
1.) The day count is weighted, and it bites earlier than 182
The 182-day rule people repeat is a Canadian idea, tied to provincial health coverage and Canadian residency. The IRS doesn’t use it. The U.S. uses the Substantial Presence Test, and it counts three years at once: all of your days this year, plus a third of last year’s days, plus a sixth of the days from the year before. Cross 183 weighted days and the IRS can treat you as a US tax resident, taxable on your worldwide income.
Run the math and it’s sneakier than people expect. Spend about 120 days a year in the U.S. every year, and you land right on the edge. Four months each winter (roughly 122 days) puts you over. Not half the year. A third of it.
There’s a release valve. If you stay under 183 actual days in the current year, you can usually file Form 8840, the Closer Connection Exception, and tell the IRS your real home is Canada. It isn’t automatic. You file it every year, by June 15.
Miss the deadline, or spend one day past 182, and the exception is gone.
The number that protects you was never 182. It’s the paperwork.
2.) Your TFSA, the account Canadians love most, is the one the IRS likes least
The TFSA is close to a national treasure. Tax-free growth, tax-free withdrawals, no catch. In Canada.
Cross the border and the catch shows up. The U.S. doesn’t recognize the TFSA as tax-free. The treaty protection that shelters your RRSP doesn’t extend to it. So the income growing “tax-free” inside your TFSA can be fully taxable to the U.S., and the account itself may be treated as a foreign trust, which drags in extra reporting forms whose penalties start in the five figures.
The reporting piece is genuinely unsettled. Cross-border tax pros still argue about exactly which forms a TFSA triggers, and the IRS hasn’t given a clean answer. When the experts aren’t sure, “assume it’s fine” is not the safe move.
3.) The RESP carries the same surprise, right when you need the money
If you opened a Registered Education Savings Plan (RESP)( for your kids, same story. The U.S. doesn’t see it as the tax-sheltered education account it is in Canada. The growth, and in some cases the government grant money, can become a US tax and reporting question at the worst possible time: when your kid starts school and you’re pulling the money out.
4.) FBAR: the form that has nothing to do with tax, and still bites
This one catches people because it isn’t about how much tax you owe. f you’re a U.S. tax resident and your Canadian accounts added together ever cross $10,000 USD at any single moment in the year, you have to report them to the U.S. Treasury on an FBAR. Chequing, savings, RRSP, TFSA, the business account, all of it, combined.
Ten thousand dollars isn’t a wealthy-person number. One paycheque or a moved-over down payment clears it. And the penalties for skipping it were built for people hiding money offshore, which means they’re harsh, and they don’t care that you simply didn’t know. The form is easy. Not knowing it exists is the expensive part.
5.) The good-news trap: your RRSP is fine, so people guard the wrong account
Here’s the flip. After all that, the account most people worry about, the RRSP, is the one the treaty actually protects.
Under the Canada-US tax treaty you can defer U.S. tax on the growth inside your RRSP until you take the money out, same as you do in Canada. The old extra form for it got scrapped years ago.
So the RRSP isn’t the danger. The danger is assuming your TFSA, your RESP, and your account balances work the way it does. They don’t, and that one wrong assumption is the thread running through every trap above.
What to actually do
None of this means stay home. It means cross the border on purpose, not by accident. Count your days for real, across three years, not just this one. Know which of your accounts the U.S. respects and which it doesn’t. File the forms before they file you. And if you’re anywhere near the lines, spend a few hundred dollars on a cross-border accountant before you spend a winter learning it the hard way. It’s the cheapest insurance in personal finance.
The Canadians who get burned are almost never careless. They’re careful people who counted to 182 and stopped. The rulebook just changed when they crossed the border, and nobody handed them the new one.
