Closer Connection Exception (Form 8840) for Canadians

Form 8840 (Closer Connection Exception) protects a Canadian from SPT if they stay under 183 days in the current year, maintain tax home and closer ties to Canada, and haven't applied for green card. Deadline June 15 (extends to October 15).

Direct answer · 60-second summary

The 60-second version

The Closer Connection Exception (Form 8840) lets a Canadian who exceeds the weighted SPT threshold but stays under 183 days in the current year retain US non-resident tax status. The form must be filed each year by June 15 (extendable to October 15 via Form 4868). It's the primary defense for typical snowbirds.

  • Strict cap: fewer than 183 days in the US in the current year.
  • Tax home in Canada (primary place of business).
  • Closer ties to Canada (housing, family, banking, license, etc.).
  • No green-card application pending.
  • Form 8840 filed on time.

Acronyms used in this guide

The 5 cumulative conditions

  1. US presence < 183 days in the current year (calendar, not weighted).
  2. Tax home in a foreign country all year — your principal economic activity is in Canada.
  3. Closer connection to one foreign country (Canada) than to the US.
  4. No application pending for Lawful Permanent Residence (green card).
  5. Form 8840 filed before the deadline.

If even one condition fails, the exception does not apply — you become a US tax resident.

Tax home: what it is

The tax home is defined by IRS as the principal place of business or employment, regardless of where the family home is. For a retired snowbird with no employment, it's the regular abode. For a consultant, it's where they do most of their business.

The tax home must be maintained all year in Canada (per Treasury Reg §301.7701(b)-2(c)). A short absence does not break the tax home as long as the principal residence stays in Canada.

Closer connection factors

IRS examines several factors to determine closer ties to Canada vs. US:

No single factor is decisive — IRS weighs the whole. The majority must lean toward Canada.
