I’m a Canadian citizen and I travel (commute) to work every day. Can I use Sprintax?

In general, residents of Canada or Mexico who regularly commute from those countries to work in the United States do not count the days they travel for the purposes of the Substantial Presence Test.

All of the visits you have done while commuting to work are not reported on Sprintax as entry and exit dates, however, please keep in mind that any other visits besides the commuting ones must be reported on Step 1 Residency status. Such visits might be your tourist visits to the US, as well as any other non-tourist ones (if any).
