Excited to share something we've been building at 49th Parallel Wealth Management.
If you split your time between the U.S. and Canada — snowbirds, dual residents, cross-border commuters — one miscounted trip can quietly trigger U.S. tax residency or put your provincial health coverage at risk. We kept seeing clients rely on memory or scattered notes to track something with real financial consequences.
So, we built Cross-Border Day Tracker, a free app that does the math for you:
*Tap-to-log calendar — mark each day as a U.S. or Canada day in seconds
*Automatic IRS Substantial Presence Test calculation — weighted across the current year and the two before it
*A year-by-year breakdown, plus a forward-looking "safe days" plan for next year
*Direct links to the actual IRS and CRA source pages, so you're never just taking our word for it
No account needed. Nothing in the app is tax, legal, or investment advice — it's a planning tool, built to sit alongside your accountant or advisor, not replace them.
Cross-Border Day Tracker launches this week on the Apple App Store — search "49th Parallel: Day Tracker" — with Android following shortly on Google Play. You can also grab it directly at 49thparallelwealthmanagement.com/day-tracker/.
If you know someone living life across the 49th parallel, send this their way.
