Tax Advisor app for Businesses In Switzerland

CHALLENGE
Create a safe application and set up the application analysis in 6 months.

SOLUTION

The taxation system of Switzerland is very complex and depends on many factors such as family situation, occupation, and place of residence. Municipal taxes vary significantly across cantons. For instance, a single employed person earning 100'000 CHF may pay anywhere between 5.5% and 18.7% depending on where he lives.

The application must is localized with Predator in:

• English
• German
• French
• Italian

All data between Web Frontend and Backend applications is transferred via the encrypted channel TLS. Certificates are extended automatically before they expire.
All user data whether it is stored locally or remotely is encrypted. Sensitive user information, like passwords, is additionally encrypted and is not stored as plain data.
User behavior is analyzed by using Google Analytics in conjunction with Google Tag Manager. The application collects:

• Personal data, but only after permission to collect it
• Behavior (visited pages and pages where interaction has started and ended)
• Session duration
• User actions on a page
• Duration per page
• etc.

The application has become the first access point for tax residents of Switzerland when it comes to choosing where to reside.
