Upgrading System Landscapes for the Aargau Cantonal Tax Authority
In 1986 the Aargau Cantonal Tax Authority (KStA) developed customised applications for the collection of cantonal taxes and direct federal taxes (billing of taxes, receivables management and accounting) as well as for the address and tax register. The applications were upgraded on a regular basis. User groups included employees of the Cantonal Tax Authority on the one hand and the tax and financial authorities of around 240 municipalities in Aargau on the other. The applications had been developed using Cobol and Delta and were run on a Unisys OS 2200 host system.
The users were extremely satisfied with the application’s functionality for cantonal tax and direct federal tax collection. The tax and address register, however, needed to be changed. On the operational side, the outdated infrastructure was generating increasing costs and there was an urgent need for an integrated system.
