Original Assessment Section
Pursuant to Sections 137.022, 138.420, Chapters 151, 153, and 155 RSMo and 12CSR30, the Missouri State Tax Commission (Commission) performs its duty of original assessment of distributable property held by railroads, certain public utilities and pipelines, commercial aircraft companies operating in air commerce, and private car companies, as well as commercial aircraft personal property.
The Commission receives a report, on an annual basis, from these entities for valuation purposes.
Values are determined for the operating unit (system value) and are then allocated to the state based on a variety of factors depending on the industry, such as plant-in-service, miles of line, operating revenues, and miles flown in Missouri.
The Commission thereafter must "assess, adjust, and equalize" the state assessed property of these companies.
Finally, the Missouri allocated value is apportioned to the counties.
