For tech-focused businesses investing in Big Sky Country, the Montana Qualified Data Center Classification Application is the gateway to securing valuable property tax classifications. This form is specifically designed for facilities that house networked computers, data storage, or networking equipment on contiguous parcels of land under single ownership. Its primary purpose is to allow these facilities to apply for a specialized tax status under Montana Code Annotated (MCA) 15-6-162. To qualify, a facility must be a heavyweight in the industry: it requires at least 25,000 square feet of new or expanded space and a massive capital investment of at least $50 million over a 48-month period, with construction starting after January 1, 2019. Successfully filing this application ensures your property—including land, improvements, and equipment—is correctly classified for tax purposes, potentially saving your business millions. However, strict deadlines apply; you must submit the completed form along with all supporting documentation by March 1 to be considered for the current tax year. This guide will walk you through every line to ensure your application is accurate and complete.
