(1) Any tax on property that is imposed on property that is subject to ad valorem taxation by any unit of local government shall be certified to the assessor each year, as provided under ORS 310.060. Except as otherwise specifically provided by law, any tax, fee, charge or assessment that is not a tax on property or is not imposed on property subject to ad valorem taxation shall not be certified to the assessor. Each tax certified shall be certified in whichever of the following forms is applicable: (a) In dollars and cents in either the total amount to be raised from all property in the unit; (b) In dollars and cents per property; or (c) As a rate per $1,000 of assessed value. (2) If any unit of local government imposes on property that is subject to ad valorem taxation a tax on property, as defined in ORS 310.140, that is not certified to the assessor under ORS 310.060 for imposition and collection, and a court of competent jurisdiction determines that the tax is subject to the limits of section 11b, Article XI of the Oregon Constitution, the unit of local government shall pay any refunds ordered by the court. No refunds shall be paid from the unsegregated tax collections account, and the assessor shall not be required to redetermine the amount of other taxes imposed on any property that also is subject to the challenged tax. (3) Notwithstanding ORS 311.806, when any unit of local government certifies a tax on property to be collected by the tax collector, and the amount of the tax on individual properties is calculated by the unit of local government, any claim for refund of such taxes due to an error in calculation of the amount of the tax shall be made to the unit of local government within the same time and in the same manner as claims for refund are to be made under ORS 311.806. The unit of local government shall pay any refunds it determines to be due to errors in calculation of the amount of the tax out of the funds available to the unit of local government. Such refunds shall not be paid from the unsegregated tax collections account, and the assessor shall not be required to redetermine the amount of other taxes imposed on the property for which the refund is made. (4) Notwithstanding ORS 311.806, when any entity that is not a unit of local government certifies an amount specifically authorized by law to be included on the roll to be collected by the tax collector, and the amount on individual properties is calculated by the entity, any claim for refund of the amount due to an error in calculation of the amount shall be made to the entity within the same time and in the same manner as claims for refunds are to be made under ORS 311.806 (2). The entity shall pay any refunds it determines to be due to errors in calculation of the amount out of the funds available to the entity. The refunds shall not be paid from the unsegregated tax collections account, and the assessor shall not be required to redetermine the amount of other taxes imposed on the property for which the refund is made.
