## What is 49th Parallel?

Cross-Border Day Tracker helps Canadians and Americans who split time between the U.S. and Canada stay on top of their tax residency status.

Core features:

Day Log — Tap any date on a calendar to mark it as a U.S. day, Canada day, or clear it. Trips are automatically compiled into a running list, viewable and editable at any time.
Status Check — See your current standing against the IRS Substantial Presence Test in real time. The app calculates your weighted 3-year total automatically (current year × 1, prior year × ⅓, year before × ⅙) and tells you plainly whether you're likely a U.S. tax resident, likely not, or approaching the threshold.
Full Report — A year-by-year breakdown showing exactly how each year's day count factors into your weighted total, plus a forward-looking projection: the maximum number of U.S. days you can spend next year while staying under the 183-day threshold.
Switch tax years — Review any past year's data, not just the current one.
No account or sign-up required to use the core tracking tool.
