The Closer Connection Exception: How the IRS Decides Where Your Life Is

The closer connection exception is the primary escape route for Canadians who meet the substantial presence test but want to remain nonresidents for US tax purposes. It is codified in IRC 7701(b)(3)(B) and claimed by filing Form 8840 with the IRS. The exception says: even though your weighted day count crossed 183, if you had a tax home in a foreign country and maintained a closer connection to that country than to the US, you are not a US tax resident.

What are the three requirements?

Requirement 1: Fewer than 183 actual days in the current year. This is the most common misunderstanding. The substantial presence test uses a weighted formula across three years to reach 183. The closer connection exception requires that your unweighted, current-year-only day count stay under 183.

• A Canadian who spends 120 days per year in the US meets the substantial presence test (because the weighted count crosses 183) but qualifies for the closer connection exception (because 120 is fewer than 183 in the current year). A Canadian who spends 185 days in the US in a single year cannot use this exception at all, regardless of how strong the connection to Canada is.
• Requirement 2: A tax home in a foreign country. Under IRC 911(d)(3), your “tax home” is your regular or principal place of business. If you are retired (no place of business), the IRS looks at where you regularly live. For most Canadian snowbirds, the tax home is in Canada because that is where they live for the majority of the year and where their financial, social, and family ties are centered.
• Requirement 3: A closer connection to the foreign country. This is the subjective factor, and the IRS evaluates it using approximately 20 factors listed in Reg. 301.7701(b)-2. No single factor is decisive. The IRS looks at the totality.

What factors does the IRS consider?

The regulations list specific facts and circumstances. In practice, the IRS gives the most weight to where your permanent home is, where your family lives, and where your most significant economic and personal ties are. The full list:

• Permanent home. Where you maintain a residence available to you year-round. A Canadian who owns a home in Toronto and rents a Florida condo for winter has a permanent home in Canada. If you own homes in both countries, the IRS looks at which one is your primary residence.
• Family. Where your spouse, common-law partner, and dependent children live. A spouse who remains in Canada year-round is a strong indicator.
• Personal belongings. Where you keep furniture, cars, clothing, jewelry, and personal effects. Maintaining a fully furnished home in Canada with personal items is evidence of a closer connection.
• Social ties. Membership in social, religious, cultural, or recreational organizations. Canadian club memberships, volunteer work, and community involvement all count.
• Professional ties. Where your professional licenses are maintained, where your business is located (if active), where your professional associations are based.
• Political ties. Where you are registered to vote, where you hold office or participate in political activities.
• Driver’s license and vehicle registration. A Canadian driver’s license and Canadian-registered vehicle support the exception. A Florida driver’s license and Florida-registered car undercut it.
• Bank accounts. Where your principal bank accounts are located. Canadian bank accounts as the primary accounts support the exception.
• Church or synagogue membership. Where your religious community is based.
• Jurisdiction of government identification. Canadian passport, provincial health card, and other government-issued ID support a Canadian connection.

The IRS does not publish a scoring rubric. But the pattern is clear: the more your life is rooted in Canada (home, family, money, community), the stronger the closer connection claim. The exception weakens when the US ties start to rival the Canadian ones, which is why buying a Florida condo and establishing Florida-based accounts requires careful attention.

Does buying US property hurt the exception?

Not automatically, but it changes the analysis. A seasonal rental (you rent a condo for 4 months each winter) has no impact on the closer connection test because you do not maintain a permanent home in the US. Buying a condo that sits empty when you are in Canada is more nuanced: you now have a dwelling available to you year-round in both countries, and the “permanent home” factor becomes a comparison rather than a clear Canadian win.

• Keep the Canadian home as the larger, more established residence. Do not register to vote in the US. Do not get a US driver’s license (a Florida ID or driver’s license is a red flag on Form 8840). Do not open US bank accounts as your primary accounts. Do not join local organizations in a way that suggests permanent settlement.
• The IRS has not ruled that owning a US property disqualifies the closer connection exception. But it does make the form more important, because you now have a US tie that the IRS can point to.

What happens if I do not file Form 8840?

Filing is technically optional (there is no standalone penalty for not filing Form 8840 by itself), but not filing has a practical consequence: if the IRS determines that you met the substantial presence test and you did not file Form 8840, you have no record of claiming the exception, and the IRS can assess you as a US tax resident for that year. The burden shifts to you to prove, after the fact, that you had a closer connection to Canada.

• The safer practice is to file Form 8840 every year that the weighted day count exceeds 183. The form is straightforward (two pages), requires no payment, and creates a contemporaneous record. It is filed by the due date of a 1040-NR (typically June 15 for nonresidents with no US wages, or April 15 if you had US wages subject to withholding), including extensions.
• If you have not filed Form 8840 for prior years and should have, the streamlined filing procedures may be available to come into compliance.

When does the closer connection fail?

The closer connection exception breaks down in several predictable scenarios:

• 183 or more actual days in the current year. The exception flatly does not apply. You need the treaty tiebreaker under Article IV instead, disclosed on Form 8833.
• Green card holder. You are a US tax resident under the lawful permanent resident test regardless of day count. The closer connection exception is irrelevant. If you want to stop being a US tax resident, you must formally abandon the green card by filing Form I-407.
• US-based life that rivals the Canadian one. If you have a full-time US home, US bank accounts, US professional memberships, a US driver’s license, US voter registration, and your family splits time equally, the IRS can deny the exception. At that point, the treaty tiebreaker (which uses a different set of tests) is the only path.
• Application for adjustment of status. If you applied for a green card or lawful permanent residency during the year, the closer connection exception is unavailable by statute (IRC 7701(b)(3)(B)(ii)).

How does this differ from the treaty tiebreaker?

The closer connection exception (Form 8840) and the treaty tiebreaker (Article IV, Form 8833) serve the same goal (avoiding US tax residency) but operate under different rules.

• The closer connection exception is a domestic US tax law provision. It does not require the treaty. It requires fewer than 183 actual days in the current year, a foreign tax home, and a closer connection. It is claimed on Form 8840, which is a simple two-page form.
• The treaty tiebreaker is a bilateral treaty provision. It applies even when the closer connection exception does not (including when you had 183 or more actual days). It uses a different hierarchy: permanent home, centre of vital interests, habitual abode, nationality. It is disclosed on Form 8833 (treaty-based return position disclosure) and typically results in filing a 1040-NR as a nonresident.
• For most Canadian snowbirds who spend fewer than 183 actual days in the US, the closer connection exception is simpler and sufficient. The treaty tiebreaker is the fallback when day counts are high or when the closer connection analysis is ambiguous.

What should I do next?

If you are a Canadian who spends part of the year in the US, the first step is calculating your substantial presence test weighted day count. If it exceeds 183, file Form 8840 every year. If your actual days in the current year reached 183 or more, the closer connection exception does not apply, and you need the treaty tiebreaker on Form 8833.
