US Tax Residency & Filing Status Wizard

Form 1040 vs 1040-NR — green card, substantial presence & treaty tie-breaker

A planning tool — not tax advice. This tool produces estimates from general rules and the numbers you enter. It is designed to orient you, not to decide for you — it cannot account for the facts that make your situation yours. Before acting on any result, speak with a qualified cross-border tax professional.
Disclaimer: This tool provides estimates for informational purposes only and does not constitute tax or legal advice. Tax residency determinations involve complex facts-and-circumstances analysis. Always consult a qualified cross-border tax professional before making filing decisions. Treaty positions in particular require careful analysis and proper disclosure. Immigration consequences of treaty elections should be reviewed with an immigration attorney. © 2026 Y2J
