About
Daysium is a day counting and tax residency compliance 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, removing 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: Understand the residency implications of your travel pattern across each country's rules.
- Strategic Planning: Model future travel to optimise your position and avoid unintended overstays.
- 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 confidence to stay compliant, without the manual effort.
Daysium brings together rule establishment, planning, monitoring, and evidencing in one place — built for the complexity of modern, globally mobile lives.
