Closer Connection Exception (Form 8840) for Canadian snowbirds

Section 01What Form 8840 is, in 30 seconds

The Closer Connection Exception was enacted by the Tax Reform Act of 1984 as part of the broader codification of US residency rules at IRC § 7701(b). Before 1984, the line between a "visitor" and a "resident" rested on case law and was unpredictable. Congress replaced that with a bright-line day-count test (the Substantial Presence Test) but recognized that pure day counts would unfairly catch foreign visitors with strong economic and personal ties elsewhere. The CCE is the relief valve.

For a typical Quebec, Ontario, Alberta, or BC snowbird who winters in Florida from November to April, the math goes like this. In the current year, suppose they spend 145 days in Florida. In each of the prior two years, suppose 130 and 120 days. The weighted SPT total is 145 + (130 ÷ 3) + (120 ÷ 6) = 145 + 43 + 20 = 208, which is well above the 183 threshold. Without intervention, this snowbird is a US tax resident, liable for worldwide-income reporting on Form 1040, FBAR, and FATCA filings. With a timely Form 8840 that documents tax home in Canada and stronger ties to Canada, the same snowbird remains a non-resident alien for the year.

Section 02Who is concerned, who is not

The Closer Connection Exception applies to Canadians who would otherwise become US tax residents under the Substantial Presence Test, but who maintain their economic and personal center of life in Canada. The typical profile is a Quebec, Ontario, Alberta, or British Columbia resident who winters in Florida from November to April, returns to Canada for spring and summer, keeps a Canadian primary residence, a Canadian driver's licence, Canadian banking, and provincial health coverage. For this reader, Form 8840 keeps the United States in non-resident tax territory and avoids the worldwide-income reporting that comes with US tax residency.

Four groups cannot use Form 8840. Canadians who spend fewer than 31 days in the US in the current year already fall below the SPT trigger and never need the form. Canadians who reach 183 days or more in the current year are blocked by the strict 183-day statutory cap on the exception, regardless of how strong their ties to Canada are. Green card holders are lawful permanent residents, which is itself US tax residence by definition. Canadians with a pending green card application (a filed Form I-485 or equivalent) are treated by the IRS as having signalled intent to remain, which defeats the closer-connection argument. US citizens, of course, are always US tax residents and never use this form.

Section 03The five cumulative conditions

Condition 1 : Fewer than 183 days in the current year. This is a strict statutory cap. The IRS counts physical presence on US soil, including transit, layovers, partial days, and same-day medical visits. A Canadian who lands in Miami at 11:59 PM on a Saturday counts that day, then the entire Sunday. Practical implication: the day count must include cross-border drive trips, airport stopovers, and medical appointments. Snowbirds who cut it close in March must be prepared to document every entry and exit (I-94 record, passport stamps, boarding passes).

Condition 2 : Tax home in a foreign country all year. The tax home, defined at Treasury Reg § 301.7701(b)-2(c), is the principal place of business or, for retirees, the regular abode. It must be in Canada for the entire calendar year, not just most of it. A Canadian who moves their tax home to Florida mid-year (selling the Canadian residence, registering a Florida driver's licence, ending RAMQ or OHIP coverage) breaks Condition 2 even if they return to Canada the following year.

Condition 3 : Closer connection to Canada than to the United States. The IRS weighs 13 factors listed on Form 8840 Part IV (permanent home, family, personal belongings, social activities, political activities, business activities, official documents, banking, etc.). No single factor is decisive; the IRS looks at the overall balance. For a typical snowbird, the balance is heavy on the Canadian side: family in Canada, Canadian driver's licence, Canadian bank as primary, provincial health card.

Condition 4 : No pending application for Lawful Permanent Residence. A filed Form I-485 (adjustment of status) or Form I-130 (immediate relative) signals intent to remain in the United States and is interpreted by the IRS as defeating the closer-connection argument. The Canadian must not have initiated any green-card pathway. Even a pending O-1 or EB-5 with downstream green-card aspiration is risky territory.

Condition 5 : Form 8840 filed on time. If the Canadian has other US-source income (rental, sale, US wages), Form 8840 is filed as an attachment to Form 1040-NR, due June 15 (or October 15 with a timely Form 4868 extension). If no other US income, Form 8840 is mailed alone to the IRS Austin Service Center by the same June 15 deadline. Filing late, without an extension, denies the exception.

Section 04Tax home: the principal-place-of-business test

The tax home concept comes from Treasury Regulation § 301.7701(b)-2(c) and is operationalized for Form 8840 purposes by IRS Publication 519. Three profiles produce three outcomes. A retiree without active business income has their tax home wherever their regular abode sits; for a snowbird, that is the Canadian residence (the place they return to year after year, where their personal effects and routine doctors are). A self-employed Canadian who consults remotely from a Sherbrooke or Mississauga home office has their tax home where the business is anchored: the home office. A Canadian who travels for work to multiple US locations but invoices from a Canadian corporation, with a Canadian bookkeeping infrastructure, also has their tax home in Canada.

The trap is the consultant or contractor who increasingly bills US clients from a Florida residence. Once the principal place of business shifts to Florida (where the client meetings happen, where the work product is produced, where the laptop sits five days a week), the tax home has shifted with it, regardless of whether the family home stays in Quebec. Condition 2 fails. The closer-connection exception is denied. The Canadian becomes a US tax resident, and the cascade begins: Form 1040 worldwide income, FBAR for Canadian bank accounts, FATCA Form 8938 disclosure, potentially loss of Canadian principal-residence exemption.

Section 05Closer connection: the 13 factor test

The 13 factors as listed on Form 8840 Part IV are: (1) location of the permanent home; (2) location of the family; (3) location of personal belongings (furniture, automobiles, jewelry); (4) location of social, political, cultural, professional, or religious organizations the filer belongs to; (5) location of business activities (other than the tax home); (6) location of the jurisdiction issuing the driver's licence; (7) location of the jurisdiction where the filer votes; (8) country of residence designated on official documents (passport, visa); (9) country listed as residence on tax forms; (10) types of official forms filed (e.g., W-9 vs W-8BEN); (11) location of charitable contributions; (12) location of financial accounts (banking, brokerage, retirement); (13) location of routine medical care.

For a Canadian snowbird whose permanent home is in Quebec, family in Quebec, car registered in Quebec, RAMQ as health coverage, Quebec driver's licence, Quebec voting registration, Canadian passport, Canadian bank as primary, family physician in Sherbrooke, and charitable donations to Canadian causes, the 13 factors point overwhelmingly to Canada. The closer-connection argument is overwhelmingly strong on paper. The Florida condo, the secondary US bank account opened for utility bills, and the Florida driver's licence (if any) are exceptions, not the rule.

Section 06Filing procedure: Form 8840 line by line

Part I : General information. Name, US taxpayer identification number if any (SSN or ITIN), Canadian address, US address if applicable, type of US visa or status (typically "B-2" or "VWP" for visa-waiver, but for Canadians the field can be left blank since Canadians enter the US without a visa). Most Canadians fill the ITIN field if they have one (because of Florida rental income or a prior FIRPTA filing); if no ITIN, the field is left blank and the form is still valid.

Part II : Days of presence over three years. Three lines: days in current year, days in first preceding year, days in second preceding year. The form then walks through the weighted SPT calculation: current × 1 + first preceding ÷ 3 + second preceding ÷ 6. The result must exceed 183 for Form 8840 to be needed (if it is below, the SPT is not triggered and no exception is required).

Part III : Tax home. Address of the foreign tax home and the dates it was maintained during the year. For a Canadian who maintained the Canadian residence the entire year, the dates are January 1 to December 31.

Part IV : Closer connection. Thirteen yes/no questions, each asking whether the factor was located in the foreign country (Canada) during the year. The pattern of answers is the substantive evidence of closer ties.

Part V : Signature. Penalties of perjury statement; the filer signs and dates.

Deadline and filing address. If the Canadian has other US-source income to declare (rental income, sale gain, US wages, US interest), Form 8840 is attached to Form 1040-NR and filed with the IRS in Austin (mailing address on Form 1040-NR instructions). The 1040-NR deadline for a Canadian is June 15 (90 days later than the standard April 15, because of nonresident status), extendable to October 15 with a timely Form 4868. If no other US-source income, Form 8840 is mailed alone to: Department of the Treasury, Internal Revenue Service Center, Austin, TX 73301-0215, by the same June 15 deadline.

Section 07Canada-side: provincial residence and reporting

Each province has its own physical-presence threshold for maintaining health coverage. Quebec (RAMQ) requires 183 days of physical presence in Quebec over a 12-month period, with limited exceptions. Ontario (OHIP) requires 153 days of physical presence in Ontario over any 12-month period. British Columbia (MSP) requires 6 months of physical presence per calendar year. Alberta (AHCIP) requires 183 days per year. A snowbird who maxes out at 182 US days has at most 183 Canadian days, which satisfies RAMQ and AHCIP but cuts the OHIP and MSP requirements close. Coordination of the US day count with the provincial day count is essential and is often the binding constraint, not the US 183-day cap.

On the Canadian side, the snowbird files a T1 General as a Canadian resident, reporting worldwide income including any Florida rental income (with foreign tax credit for any US tax paid), and any US-source pension or investment income. If the Canadian owns Florida real estate with a total cost above CAD 100,000, they also file Form T1135 (Foreign Income Verification Statement) every year, regardless of whether the property generated income. The CRA penalty for missing T1135 is steep (CAD 25 per day, up to CAD 2,500) and is consistently enforced.

Section 08Worked example: a Quebec snowbird with 145 days

SPT calculation. Weighted total = 145 + (130 ÷ 3) + (120 ÷ 6) = 145 + 43.33 + 20 = 208.33. This exceeds 183, so the SPT is triggered. Without a defence, Pierre is a US tax resident for the year.

Strict 183-day cap on the exception. Pierre's current-year days are 145, which is below 183. Condition 1 is satisfied.

Tax home (Condition 2). Pierre's tax home is his Sherbrooke condominium, the regular abode where his personal effects, primary care physician, and routine daily life sit. He maintained this residence all year. Condition 2 is satisfied.

Closer connection (Condition 3). Pierre answers the 13 questions on Form 8840 Part IV. Permanent home: Sherbrooke. Family: Quebec (wife, two adult children, three grandchildren). Personal belongings: most in Sherbrooke (his car, his furniture, his sailboat at Lac Memphrémagog). Social activities: his Sherbrooke curling club, his church in Magog. Driver's licence: Quebec. Voting registration: Sherbrooke. Passport: Canadian. Bank: Desjardins. Charitable donations: Centraide and the Sherbrooke food bank. Medical care: family doctor in Sherbrooke, dentist in Magog. The Florida condo is owned, but it is the only US-side factor. Condition 3 is satisfied.

No green card pending (Condition 4). Pierre has not applied. Condition 4 is satisfied.

Form 8840 filed on time (Condition 5). Pierre has no US-source income to report (his condo is not rented). He mails Form 8840 alone to Austin by June 15. Condition 5 is satisfied.

Outcome. Pierre files Form 8840, retains his US non-resident status, files only his Canadian T1 (with no US tax exposure on his Canadian retirement income), and continues to qualify for RAMQ because he spent 220 days in Quebec (above the 183 threshold). The cross-border tax plan holds for another year.

Section 09Common mistakes

• Exceeding 183 days in the current year. The strict cap is non-negotiable. A snowbird who lands in Florida on November 1 and leaves on May 2 is past 183 days. The Closer Connection Exception is gone. The fall-back is the Canada-US treaty tie-breaker under Article IV, which works but requires more documentation and is contested more often.
• Not filing Form 8840 at all. Silence is interpreted by the IRS as default US residency for any Canadian who triggered the SPT. The form is the affirmative claim of non-residence. No form, no claim.
• Having or applying for a green card. A pending Form I-485 or I-130 defeats Condition 4. A Canadian who initiates the green-card process for any family member should not claim Form 8840 themselves until they have closed the application or withdrawn.
• Ambiguous tax home (the consultant trap). A Canadian who works remotely from Florida for US clients for more than half the year has effectively moved their tax home to the United States. Condition 2 fails. Filing Form 8840 anyway and signing the perjury statement is a serious error.
• Filing late without Form 4868 extension. The June 15 deadline is firm. The October 15 extension requires a Form 4868 filed by June 15. A Canadian who files Form 8840 in August without an extension has filed late, and the IRS denies the exception.
• Forgetting the provincial threshold. A snowbird who maxes out the US day count can quietly lose provincial health coverage. OHIP, MSP, and AHCIP all have their own thresholds. Form 8840 protects against US tax residence but not against provincial residency loss.
• Letting the I-94 record drift. The IRS will rely on the I-94 record (retrievable at i94.cbp.dhs.gov) if there is any audit question. Snowbirds who fail to retrieve their I-94 history annually risk inheriting a CBP error (entry recorded that was actually a transit, or vice versa) that they cannot easily contest.

Section 10Preparation checklist

1. Keep a running day-count log for the current year and the previous two years, including partial days and transit days. Reconcile against the I-94 record every March.
2. Maintain the Canadian residence as the primary home: physical presence above the provincial threshold, mail forwarded to the Canadian address, primary care physician in Canada.
3. Keep the Canadian driver's licence as the primary licence. Do not apply for a Florida licence unless the Canadian one has been surrendered for a documented reason.
4. Keep a Canadian financial institution as the primary banking relationship. Use the US bank only for utility bills and HOA payments.
5. Document charitable contributions to Canadian organizations (receipts retained for both Canadian tax deduction and Form 8840 Part IV evidence).
6. Track voting registration: vote at every federal and provincial Canadian election. The pattern of voting is an evidentiary anchor.
7. Set a calendar reminder on May 15 each year to begin the Form 8840 preparation. The form itself takes 30 minutes if the day-count log is current.
8. If other US-source income is present (rental, sale, interest), prepare Form 1040-NR alongside Form 8840 and file by June 15 together.
9. File Form 4868 by June 15 only if needed to push the filing to October 15; otherwise file Form 8840 directly.
10. Retain a copy of the filed Form 8840, the IRS receipt confirmation (certified mail or USPS tracking), and all supporting evidence for at least seven years.

Section 11Frequently asked questions

Section 12Scope: what this guide does not cover

This guide covers the Closer Connection Exception under IRC § 7701(b)(3)(B) and the procedural Form 8840 filing. It does not cover the Canada-US treaty tie-breaker under Article IV of the 1980 Convention, which is the fall-back when the strict 183-day cap is exceeded; that mechanism requires Form 8833 disclosure and is covered in a separate guide. It does not cover green-card pathways (EB-5, family sponsorship, employment-based), which are immigration topics outside this scope. It does not cover the full Form 1040-NR process for a Canadian with US rental or sale income; that is the subject of dedicated guides on FIRPTA, IRC § 871(d) net election, and Form W-8ECI. It does not cover the ITIN application via Form W-7, which is itself a multi-week process that should be initiated before the first US-source income event.

Professional consultation: any Canadian whose situation borders the limits of the exception (more than 160 US days per year, US work income, US LLC ownership, mixed residence with a US spouse, pending immigration) should consult a cross-border tax attorney or a CPA with cross-border specialty before filing Form 8840 on their own. The 30-minute form belies the consequences of an incorrect filing.
