ExpatEngine is built around a simple idea: many cross-border questions are better answered by a small, well-designed tool than by twenty tabs of search results.
The site focuses on practical decisions — whether a special tax regime may fit a salary and profile, how many Schengen days remain, and when a residence-duration milestone may be reached.
The tools use structured facts so that the same rule can power a calculator, directory and explanation page without drifting into different versions. We prefer primary government and authority sources for hard thresholds and legal timelines.
ExpatEngine is an independent information site. Tool results are planning aids and do not create tax, immigration or legal entitlement.
