Or. Admin. R. 150-311-0170 - What is an "Error or Omission on the Roll of Any Kind"

(1) The officer may correct an error or omission on the roll of any kind if the correction does not require the exercise of valuation judgment. "Valuation judgment" includes but is not limited to selection of appraisal methodology or the estimation of functional and economic obsolescence adjustments. Errors or omissions that may be corrected under this subsection include, but are not limited to:
(a) The elimination of an assessment to one taxpayer of property belonging to another on the assessment date.
Example 1: If a deed of a sale is never recorded, the assessor records would not reflect the new ownership. Because the records do not reflect the correct information, it is not correctable as a clerical error but is correctable as an error or omission on the roll of any kind.
(b) The assessment of property more than once for the same year or assessment of nonexistent property.
(c) The placement of property on the assessment and tax roll of the wrong county or assessment on behalf of the wrong jurisdiction.
Example 2: A utility company reported certain wire and pipe mileage as being in one code area when it was in fact located in another area.
(d) The elimination or partial elimination of an assessment of property that is entitled to exemption from taxation or special assessment or entitled to partial exemption from taxation.
(e) The elimination or partial elimination of an assessment of personal property resulting from an error made by the taxpayer on a personal property return if the personal property is entitled to exemption or is otherwise not taxable.
(f) The correction of a value changed on appeal.
(g) The application of an incorrect trending or indexing factor.
Example 3: The trending factor developed for the property class in the area is 115. Through a transposition, a factor of 151 is incorrectly applied. This is a correctable error.
(h) The use of the wrong property classification.
Example 4: The property is an improved single family residential property that is classified 1-0-1. The property was incorrectly classed as a 2-0-1 and therefore received the wrong trend factor. Both the property classification and the trend factor may be corrected.
Example 5: The assessor has assessed farm property at market value on the belief that the zoning was not Exclusive Farm Use. Later the assessor discovers the land was in an Exclusive Farm Use Zone and should have been assessed at its farm use value. Because the records of the assessor failed to reflect the proper status of the property , this is not correctable as a clerical error. Because a correction can be made without the use of appraisal judgment, this is not a case of valuation judgment under ORS 311.205(1)(b) and is correctable as an error or omission on the roll of another kind.
(i) The correction of an error or omission in the computation or application of the tax rate.
Example 6: A tax rate error is correctable. A water district shares boundaries with a city. The city annexes property from the water district. The boundary change information was not filed timely with the assessor and the Department of Revenue and should not have been considered in the calculation of the taxes. The county should make the correction to the tax calculation and refund or assess the properties in the districts as appropriate so they have been assessed the correct amount of tax
(j) The correction of an error or omission on the roll that arises from inaccurate reporting of assets, or of facts about assets by a taxpayer on a return filed under ORS 308.290.
Example 7: A taxpayer reports a machinery asset on both its real and personal property accounts. The cost is double-reported for valuation purposes.
Example 8: A taxpayer reports assets transferred to the site at their net book value rather than original cost. The cost is inaccurately reported for valuation purposes.

This error or omission may be corrected only if the incorrect calculation of value was a result of a simple mathematical extension and does not require a new valuation judgment.

(A) The error or omission may be corrected if the taxpayer subsequently provides accurate asset information, and if no additional or different valuation judgment is required to make the correction.
(B) When a correction of inaccurate reporting of assets or of facts about assets by a taxpayer results in a reduction of tax and a refund under ORS 311.806, no interest is paid under 311.812.
