DualTaxCheck is a free educational tool that helps digital nomads, remote employees, and cross-border workers understand when they might be triggering tax residency in more than one country at once — before it becomes an expensive surprise.
High-net-worth remote freelancers, cross-border remote employees, digital nomads moving through popular long-stay destinations, and founders running businesses from abroad. If you split your year across more than one country, this tool is built for you.
The checker asks about your home country, the country you want to evaluate, the days you've spent there, and a few yes/no questions about housing, family, and income sources. It runs those answers against simplified versions of each country's publicly available residency rules — day-count thresholds, habitual-abode tests, and center-of-interest tests — to produce a High/Medium/Low risk level and an explanation of which specific rule you're closest to triggering.
For Canadian users evaluating US presence, the tool runs a dedicated module based on the IRS Substantial Presence Test's three-year weighted formula.
This tool does not provide tax, legal, or immigration advice. It is a general-education resource only. Tax residency law is complex, changes frequently, varies by treaty, and depends on details this tool cannot capture — including bilateral tax treaties, your full income picture, and country-specific administrative practice.
Nothing on this site creates a professional relationship between you and DualTaxCheck or any affiliated party. Results are estimates based on simplified, publicly available rules current as of mid-2026 and may not reflect recent legal changes, your specific circumstances, or how a given tax authority would actually rule in your case. Before making any decision based on your results, consult a licensed tax professional or immigration attorney qualified in the relevant jurisdictions.
We are not liable for any financial, legal, or tax consequences arising from your use of this tool or reliance on its output.
