(2) For purposes of this section, a clerical error is an error on the roll that arises from an error in the records of the Department of Revenue and that, had it been discovered by the department prior to certification of the roll, would have been corrected as a matter of course, and for which the information necessary to correct the error is contained in the records of the department. Clerical errors include, but are not limited to, arithmetic or copying errors or the omission or misstatement of a property value on the roll.

(3) Except as provided in subsection (4) of this section, the director may correct any other error or omission of any kind, including, but not limited to:

(a) The elimination of the assessment to one person or company of property owned or used by another person or company on the assessment date;

(b) The correction of a value changed on appeal;

(c) The correction of an error in the assessed value of property resulting from an error in the identification of a unit of property;

(d) An error in apportionment of assessments on the roll; and

(e) An error in the ratio of average maximum assessed value to average real market value determined under ORS 308.153.

(4) For purposes of this section, the director may not correct an error in valuation judgment that is an error in the department’s opinion of the value of property.

(5) Corrections may be made under this section to the roll last certified, or to the certified roll for any prior year that does not exceed five years prior to the year for which the last roll was certified under ORS 308.621.

(6) If the director makes a correction under this section that has the effect of increasing the assessment to which the correction relates, except where the correction is made to correct a value changed on appeal, the department shall treat the correction as an addition of omitted property for purposes of giving the notice required under ORS 308.632.
