Giant created systems for the registering, assessing and collection of GST into the Tax Office's existing systems.

Taxpayers registering for GST or making GST returns are able to send in paper-based returns which are then processed by Giant's forms recognition system, or file returns online using Giant's online tax returns system.

Giant produced a suite of OpenVMS applications to handle GST assessing and enhanced the internal database to store GST data. Workflows were used for the verification of GST returns and reporting and auditing applications were also developed.

Since 2008, over 0 GST returns have been successfully processed.
