Form 8840 for Snowbirds — The Closer Connection Exception, Explained

If you read our article on the substantial presence test, you know the uncomfortable math: a routine snowbird winter of about four months a year is enough to make you a U.S. tax resident under the IRS's weighted day-count formula. The good news is that Congress built an exit specifically for people in your situation — the closer connection exception — and claiming it requires one annual filing: Form 8840.

This article explains who qualifies, what the form actually asks, when it's due, and the handful of mistakes that turn a routine filing into a real problem. The usual caveat applies: this is the general framework. Your visa history, day counts, and ties decide your actual position, and edge cases deserve professional eyes.

What Form 8840 does

Form 8840 — the Closer Connection Exception Statement for Aliens — tells the IRS, in effect: "Yes, my days meet your substantial presence formula, but my life is in Canada, and here's the evidence." Filed correctly and on time, it preserves your status as a nonresident for U.S. tax purposes despite meeting the day-count test. No U.S. tax return on your worldwide income. No U.S. foreign-account reporting regime. One form, each year you need it.

It is not an application that gets approved or denied like a visa — it's a statement you're entitled to make if you meet the conditions. The work is in meeting the conditions and proving them.

The three conditions

You can claim the closer connection exception for a year if all three are true:

1. You were in the U.S. fewer than 183 actual days in the current year. Not weighted days — actual, physical days in that calendar year, counting any part of a day as a day. This is the hard ceiling. At 183 or more actual days, Form 8840 is simply unavailable, no matter how Canadian your life is. (A treaty tie-breaker position may still rescue you, but that's a different filing and a different article.)

2. Your tax home was in Canada for the whole year. Your tax home is, roughly, where your regular place of work or — for retirees — your regular place of living is. For a typical snowbird whose permanent home, finances, and life base are in Canada, this is straightforward.

3. You had a closer connection to Canada than to the U.S. This is where the form gets specific. The IRS looks at the fabric of your life and asks where it's actually woven.

What "closer connection" means in practice

Form 8840 asks a series of pointed questions, and together they sketch the picture the IRS evaluates:

• Where is your permanent home — and do you own or rent in each country?
• Where are your family, your belongings, your vehicles?
• Where do you hold your driver's licence? Where are you registered to vote?
• Where are your bank accounts and investments managed?
• Where do you carry health coverage?
• Which country did you list as your residence on official documents?

No single answer decides it; the pattern does. A snowbird with a paid-off house in Ontario, Ontario health coverage, an Ontario licence, Canadian banking, and a rented Florida condo for the winter is a textbook closer-connection case. The picture muddies when people start accumulating U.S. anchors — buying the Florida home while renting in Canada, getting a Florida driver's licence for convenience, moving investment accounts south. Each of those choices may be sensible on its own; together they erode the very claim the form exists to make.

One disqualifier to know: if you've applied for a U.S. green card or taken steps toward U.S. permanent residence, the closer connection exception is off the table — you can't simultaneously tell one arm of the U.S. government you're moving in and another that your life is elsewhere.

The deadline, and why it matters more than people think

For a snowbird with no other U.S. filing obligation, Form 8840 is due by June 15 of the following year (filed on its own, mailed to the IRS; if you do have to file a U.S. nonresident return, the 8840 attaches to it).

Here's the part that deserves bold type: filing late or not at all can forfeit the exception itself. Miss the filing, and the IRS can hold you to the default — U.S. tax residency under the substantial presence test — unless you can show by clear and convincing evidence that you took reasonable actions to comply and had good cause. That's a hard, retroactive argument to win. The form takes less time to complete than a border crossing; the failure to file it can take years to untangle.

Two housekeeping points that trip up couples: the form is per person — each spouse who meets the day-count test files their own 8840, even if your travel is identical. And it's per year — a habitual snowbird files it annually, as a routine, like renewing insurance.

The mistakes we see most

After enough snowbird files, the same handful of errors keeps appearing:

1. Counting days from memory — and undercounting, because arrival and departure days both count. Keep a log; the U.S. and Canada share border-crossing data, so your number is checkable.
2. Assuming "under six months" means no filing needed. The substantial presence formula triggers around a 120-day annual habit. Under 183 days means 8840 is available, not that it's unnecessary.
3. Quietly accumulating U.S. ties — the Florida licence, the U.S. bank as the primary account — without realizing each one weakens the closer-connection picture.
4. Filing once and forgetting. The exception is annual. Last year's form does nothing for this year's days.
5. Sailing past 183 actual days because of an extended stay — a renovation, a family matter — without realizing the 8840 route just closed and a treaty filing is now required instead.

The practical takeaway

For most Canadian snowbirds, Form 8840 is the entire price of keeping the IRS out of your worldwide income: one page, once a year, on time, backed by an honest day log and a life that genuinely remains anchored in Canada. The stakes of skipping it are wildly disproportionate to the effort of filing it.

This is precisely what our Snowbird Annual Package handles: we track your days against the formula, prepare and file Form 8840 each year, watch for the situations where the 8840 route closes and a treaty position is needed instead, and stay available for the "can I stay three more weeks?" questions year-round. If you just want to know where you stand first, the cross-border assessment maps your day count and filing position before you commit to anything. Either way — file the form. It's the cheapest peace of mind in cross-border life.
