The department relies on commercial property owners to provide their income and expense information to assist in the department’s determination of fair and equitable commercial property values statewide. The department analyzes the data submitted to determine typical market rents, expense percentages and capitalization rates of similar commercial properties. The data is used to develop specific property type income models used statewide in the mass appraisal process.
The department keeps all income and expense information reported confidential. Reporting income and expense information is not required. However, if commercial property owners do not provide the information, it may limit their ability to appeal their property value determined by the department for tax purposes. (15-1-303, MCA)
