About Daysium
Daysium is a day counting and tax residency evidence platform for globally mobile individuals. The app elegantly resolves the risks and complexities of day counting and record-keeping. Key Daysium Features: - Automated Location Logging: Your phone's GPS captures location data automatically, minimising the risk of gaps in your record. - Photographic Evidence: Upload geo-tagged photos to build an auditable record of your presence in each jurisdiction. - Multi-Jurisdiction Tax Rules: See your day count and status against each country's coded tax residency rules, wherever your travel takes you. - Strategic Planning: Model future travel against the rules, so you can see the impact on your day counts before you go. - No More Spreadsheets: Replace manual day counting with a single, reliable platform. Managing tax residence across multiple jurisdictions is complex, and one miscounted day can carry significant financial consequences. Daysium gives you the precision and the record to demonstrate reasonable care, without the manual effort. Daysium brings together rule establishment, planning, day counting and evidencing in one place — built for the complexity of modern, globally mobile lives.
