Mont. Code Ann. § 15-10-305 — Clerk And Recorder To Report Mill Levy -- Department To Compute And Enter Taxes

15-10-305 . Clerk and recorder to report mill levy -- department to compute and enter taxes. (1) (a) The county clerk and recorder shall by the second Monday in September or within 30 calendar days after receiving certified taxable values notify the department of the number of mills needed to be levied for each taxing jurisdiction in the county. Except as provided in subsection (1)(b), the department shall compute the taxes by multiplying the number of mills times the taxable value of the property to be taxed and shall add any fees or assessments required to be levied against a person owning property. All taxes, fees, and assessments must be itemized for the property listed in the property tax record.
(b) Except as provided in 15-6-244 regarding property that has been granted a residential subdivision property tax exemption and in 15-6-506 regarding a property tax exemption for a senior care and housing development project, in conveyances that result in a land split, the taxes must be based on the property as assessed on January 1 preceding the conveyance. The department is not required to include the name of the new owner in the computation of the amount of taxes, fees, and assessments to be levied against property that is part of a land conveyance if including the new owner's name would cause the department to violate the deadline provided in subsection (2).
(2) The department shall complete the computation of the amount of taxes, fees, and assessments to be levied against the property and shall notify the county clerk and recorder and the county treasurer by the second Monday in October. Notwithstanding the provisions of 15-10-321 , if a county clerk and recorder fails to timely notify the department of the number of mills needed to be levied for each taxing jurisdiction in that county in accordance with subsection (1)(a), the department must have additional time to meet the notification requirement of this subsection (2) equal to the number of days that the notification required in subsection (1)(a) was received late by the department.
