The U.S. I-94 tool shows recent entries instantly; the CBSA report is requested (free) and mailed. Some land crossings may not appear — keep your own records too.
Convenience tool — keep your own records. This tracker helps you stay aware of your day counts, but it is not an official record. Always keep supporting records (passport stamps, boarding passes, border logs). Educational only — not tax or legal advice.

Not sure the 8840 or treaty rules apply to you?
A free 20-minute call with a dual-licensed cross-border advisor (CFP® in Canada & the U.S.) will confirm exactly where you stand.
Simplified estimate — not tax or legal advice. The Substantial Presence Test counts all U.S. days in the test year, ⅓ of the prior year's, and ⅙ of the year before; you may be treated as a U.S. tax resident if that total reaches 183 and you were present at least 31 days in the test year. This tool does not account for exempt individuals, the Closer Connection Exception (Form 8840), or the Canada–U.S. treaty tie-breaker (Form 8833). Verify with a cross-border professional before acting.
