This initiative relates to the replacement of the current Property Assessment and Taxation office (PAT) systems, with a single, modern, end-to-end property assessment, valuation, and taxation platform for use within the Yukon Territory. The PAT office has determined a replacement system is needed, as there is concern regarding the future support of the mainframe infrastructure. The new system implemented is called the ATENT Assessment & Tax (ATENT system). It is a property assessment and tax solution that provides a web-based, GIS-enabled tool set to help agencies, such as PAT, manage appraiser business processes and the entire property tax life cycle. It is a comprehensive solution delivering a suite of tools for computer-aided mass appraisal, personal property valuation, assessment administration, and tax billing.
