Question 1

How many days can a Canadian spend in the US without becoming a tax resident?

Accepted Answer

There is no single yearly number. The IRS Substantial Presence Test adds your current-year days in full, one third of last year's days, and one sixth of the days from two years ago. If that weighted total reaches 183 and you were present at least 31 days in the current year, the IRS can treat you as a US tax resident. As a rule of thumb, repeating about 120 days every year keeps you just under, while about 122 days every year crosses the line.

Question 2

What is the Substantial Presence Test?

Accepted Answer

It is the test the IRS uses to decide whether a non-citizen is a US tax resident based on time spent in the country. The formula is current-year days plus one third of the prior year plus one sixth of the year before that. Reaching 183 weighted days, with at least 31 days in the current year, makes you a resident for US tax purposes unless an exception applies. Source: IRS Publication 519.

Question 3

How does a snowbird avoid US tax residency?

Accepted Answer

If you were in the US fewer than 183 days in the current year, you can usually claim the Closer Connection Exception by filing Form 8840 by the deadline each year, showing your tax home and stronger ties remain in Canada. It must be filed every year. At 183 or more US days in a single year the exception is unavailable, and a Canada-US treaty position on Form 8833 may be the only route.

Question 4

Do all my days in the US count toward the Substantial Presence Test?

Accepted Answer

Most do, but some are excluded. Days you regularly commute to work from Canada, time in transit through the US of under 24 hours, days you intended to leave but could not because of a medical condition that arose while you were there, and days as an exempt individual do not count. The detailed rules are in IRS Publication 519.

Question 5

How long can a Canadian snowbird stay in Florida or Arizona before owing US taxes?

Accepted Answer

There is no fixed number of days that triggers US tax. The IRS uses the Substantial Presence Test, a three-year weighted count, not a simple annual limit. Spending about 120 days a year, every year, keeps most snowbirds just under the line. Cross it and you may need to file Form 8840 to claim a closer connection to Canada. Use the Day Counter to see your exact weighted total.

Question 6

Is the 183-day rule real?

Accepted Answer

Not the way most people think. There is no single rule that lets a Canadian stay 182 days a year forever with no US tax consequences. The 183 figure is the threshold in the IRS three-year weighted formula, where this year's days count fully, last year's count one third, and the year before one sixth. You can cross 183 weighted days while spending well under 183 days in any single year.
