New website for the Norwegian Tax Administration

Customer story

The Norwegian Tax Administration's website is among the most visited websites in Norway. twoday created a new website to make it easier for individuals and businesses to access information and services. 

The Challenge

The Tax Administration wanted new and modern websites with a clear focus on universal design and responsive design. As part of the modernization, the Tax Administration wanted to review all content.

In terms of volume, the Tax Administration has well over 100,000 elements in the form of pages and files offered through the portal. A complete re-establishment of the new portal was needed, and twoday was the total provider, which involves development, operation, maintenance, management, and licenses. Thus, twoday took responsibility for all aspects. The Tax Administration provided a large project team that we worked with closely and continue to do so.

The Solution

Quality and structure are essential for the Tax Administration. Therefore, each page was manually quality assured and placed in the correct position in the new hierarchy. The website also had to be available on PC, mobile, and tablet.

In parallel, a separate calculator project written in .NET Core and Vue.JS is developed and operated, which is about calculating and paying the one-time vehicle tax. This project has integrations with both the internal system, external system at the Norwegian Public Roads Administration and the Norwegian Customs, as well as the payment solution NETS. For the end-user, the calculators are presented as an integrated part of the new website. Parallel with the development of the portal, the customer has developed a new API that the solution uses.

A re-establishment of one of Norway's most visited websites - Cloud services was the key to success.

The Value

The new solution provides greater flexibility and the ability to handle large amounts of traffic at certain times while maintaining security requirements and a low cost level.

This is ensured through a platform of cloud services that utilizes Microsoft's Public Cloud, Azure. Cloud services have thus been the key to handling periods of high demand.

The new portal offers users a completely new graphical and structural profile on the pages. The portal meets all requirements for public websites for universal design and is responsive.
