Tracking Time in the United States
Whether to escape winter, visit family, or attend a meeting, Canadians visit the United States often and for considerable periods of time. Talking to frequent US visitors, it is common to hear, “I always stay less than 180 days a year so I do not get taxed.”

The IRS applies the Substantial Presence Test (SPT) to determine if individuals (who are not citizens or permanent residents) are considered residents for tax purposes.
