Daysium is a smartphone app that automates day counting and evidence collection to help internationally mobile individuals stay compliant with tax residency rules.

Daysium is designed for high-net-worth individuals, globally mobile individuals, digital nomads, and cross-border employees who are at risk of triggering tax obligations in multiple jurisdictions.

The Daysium mobile app uses the clients mobile phone location data to create an automatically generated timeline as they move from place to place. This enables us to count days by tax law which we’ve coded into the platform. Additionally, users can add evidence to their timeline to prove they were at a location.

Spreadsheets rely on memory and manual input. It’s an outdated method that is time consuming and prone to human error. Daysium automates the process, captures data passively, and provides defensible records that stand up in tax disputes. There’s no guesswork or reliance on memory.

Once you’ve agreed to join Daysium, we’ll give you access to all of our onboarding materials, templates, and marketing assets. We’ll also announce the partnership on our social media and website. You can introduce your clients to Daysium and direct them to our website to register.

You can use our email and social media templates, mention Daysium during your advisory meetings and direct clients to our website. We’ve learned over time that introducing your client to our CEO, Tim Huelin ([email protected]), by email is a quick and effortless introduction, which also acts as a handover when the topic of day counting and record-keeping comes up.

All resources are available in the 'Welcome to the Daysium Partner Network' guide. Please contact our marketing team at [email protected] if you have any problems accessing the files or questions related to these materials.

We offer co-branding opportunities for selected partners and recommend adding a Daysium logo to your firm’s website to showcase the partnerships. These backlinks act as a mutually beneficial way to build authority online. Connect with our team at [email protected] to learn more.

We don’t usually provide a free trial account to clients, however we demo all features of the app on an onboarding call that is booked with your client after you introduce them to us.
