IN THE OREGON TAX COURT MAGISTRATE DIVISION Property Tax
JERRY WILLEY, ) and JUDY WILLEY, ) ) Plaintiffs, ) TC-MD 250613N ) v. ) ) WASHINGTON COUNTY ASSESSOR, ) ) Defendant. ) DECISION
Plaintiffs appealed Defendant’s letter dated August 8, 2025, denying Plaintiffs’
Application for Correction of Maximum Assessed Value (Application) for property identified as
Account R2100956 (subject property). (Compl at 7.) Plaintiffs identified the tax years at issue
as 2020 to 2024. (Id. at 1.) At the case management conference held December 10, 2025,
Plaintiffs moved for summary judgment on their Complaint. (Journal Entry, Dec 10, 2025.) As
agreed upon by the parties, Defendant filed a cross motion for summary judgment and response
to Plaintiffs’ motion. Plaintiffs had the opportunity to file a reply but did not do so. By letter
dated February 10, 2026, the court requested additional briefing on whether another error
correction statute – ORS 311.205 – applies in this case. Defendant filed its Supplemental Brief
on March 16, 2026. Plaintiffs did not reply. This matter is ready for decision.
I. STATEMENT OF FACTS
Plaintiffs filed their Application in March 2025, describing the property with the square
footage error as “unfinished attic space.” (Compl at 8.) Plaintiffs assert that, in 2008, Defendant
increased “the livable space” of the subject property by 525 square feet “to reflect the attic space
above the garage.” (Id. at 2.) Plaintiffs note a 5.8 percent increase in the amount of tax assessed
on the subject property between the 2008-09 and 2009-10 tax years. (Id. at 6.) Plaintiffs
DECISION TC-MD 250613N 1 purchased the subject property in 2007 and did not add “any additional space from 2007 through
now, 2025.” (Id. at 2.) Plaintiffs believe that they “have incorrectly paid tax on this additional
525 sq ft for 17 years.” (Id.)
Defendant denied Plaintiffs’ Application under ORS 311.234(3)(b)(B), explaining that
the difference between “finished second-floor space and unfinished attic storage space” is “a
difference in the nature, extent, or value of the improvements” and so “does not qualify for
correction.” (Compl at 7.) Defendant does not “dispute that the attic space existed” or “the
square footage of the space[.]” (Def’s Mot for Summ J at 1.) Defendant agrees that it added
exception value in 2008 for “an additional 525 square feet of finished living area, attributed to
attic space located above the garage.” (Id. at 2.) Since then, Defendant “has confirmed that the
space in question is unfinished attic storage and was misclassified as finished living area.” (Id.)
As a result, Defendant corrected the subject property’s real market value (RMV) but did not
change its maximum assessed value (MAV). (Id.)
II. ANALYSIS
The issue is whether the subject property’s MAV may be corrected for the 2020-21 to
2024-25 tax years based on an error in the 2008-09 tax year that misclassified a portion of the
subject property as finished living space rather than unfinished space. The court considers
whether the correction may be made under either ORS 311.234 or ORS 311.205.1 The court
grants a motion for summary judgment if all the documents on file “show that there is no
genuine issue as to any material fact and that the moving party is entitled to prevail as a matter of
law.” Tax Court Rule (TCR) 47 C.2
1 The court’s references to the Oregon Revised Statutes (ORS) are to 2023. 2 TCR 47 is made applicable by Tax Court Rule-Magistrate Division (TCR-MD) 13 B, which provides that “[t]he court may apply TCR 47 to motions for summary judgement, to the extent relevant.”
DECISION TC-MD 250613N 2 A. Correction of Error in Square Footage Under ORS 311.234
ORS 311.234 permits a property owner to petition the assessor for a MAV correction for
up to five tax years based on a square footage error or taxation of nonexistent property.3
Plaintiffs argue that the error at issue here is a square footage error that may be corrected under
the statute. (See Compl at 2.) ORS 311.234(2)(a) requires the assessor to correct a property’s
MAV if the petitioner demonstrates “[a] difference between the actual square footage of the
property as of the assessment date for the tax year and the square footage of the property as
shown in the records of the assessor for the tax year.” Defendant disagrees that the error is a
square footage error, instead characterizing it as a valuation error. (Def’s Supp Br at 3.)
Defendant relies on ORS 311.234(3)(b)(B), which states that the correction
“[m]ay not be made to the extent that the assessor finds that the new property or new improvements to property existed on the assessment date of a prior tax year and the petition is best construed as demonstrating a difference in the nature, extent or value of the new property or new improvements to property.”
(Def’s Mot for Summ J at 2-3.) Defendant reasons that “the square footage itself” was correct;
the error was in its classification as finished instead of unfinished. (Id. at 3.)
In a case presenting similar facts, this court concluded that an error misclassifying a
sunroom as living space was not an error in square footage correctible under ORS 311.234.
Wynne v. Marion County Assessor, TC-MD 170207R, 2018 WL 3428754 (Or Tax M Div,
Jul 16, 2018). The court considered legislative intent, finding that the legislature was concerned
about taxation of nonexistent property, whereas the sunroom at issue existed. Id. at *3. The
court finds the reasoning of Wynne persuasive and reaches the same conclusion.

error, not a square footage error. As a result, the error may not be corrected under ORS 311.234.

DECISION TC-MD 250613N 2 A. Correction of Error in Square Footage Under ORS 311.234
ORS 311.234 permits a property owner to petition the assessor for a MAV correction for
up to five tax years based on a square footage error or taxation of nonexistent property.3
Plaintiffs argue that the error at issue here is a square footage error that may be corrected under

3 Plaintiffs have not alleged that the attic space did not exist or argued that that provision of the statute applies.
DECISION TC-MD 250613N 3 Defendant’s error classifying the attic space as finished rather than unfinished was a valuation
error, not a square footage error. As a result, the error may not be corrected under ORS 311.234.
B. Correction of Valuation Judgment Errors under ORS 311.205.
Having concluded that the error at issue in this case was one of valuation judgment, the
court next considers whether it may be corrected under ORS 311.205. That statute permits the
officer in charge of the roll to correct errors in “valuation judgment” for up to five years “at any
time in any account when an appeal has been filed in the tax court alleging that the value on the
roll is incorrect, if the correction results in a reduction of the tax owed on the account.”
ORS 311.205(1)(b)(A). Defendant determined that provision does not apply here because
Plaintiffs did not make a timely valuation appeal and the subject property’s MAV was correctly
computed for the five years open for correction under ORS 311.205. (See Def’s Supp Br at 2-3,
citing OAR 150-311-0150(3) (limiting correction to timely appeals within the court’s
jurisdiction).)
The court agrees with Defendant. The valuation error at issue here occurred in the
2008-09 tax year and no timely valuation appeal was made for that year. See Richardson v.
Dept. of Rev., 22 OTR 207, 208-209 (2016) (describing ways to appeal value). This court has
rejected the theory that an earlier, unchallenged error in RMV carries through to a subsequent
MAV through a “series of errors.” Kaufman v. Dept. of Rev., 20 OTR 159, 165-166 (2010); see
also Richardson, 22 OTR at 211 (dismissing appeal of 2012-13 through 2014-15 tax years based
on alleged error in 2001-02 tax year). MAV is calculated in accordance with ORS 308.146.
Plaintiffs have not presented evidence or alleged that the subject property’s MAV was
DECISION TC-MD 250613N 4 miscalculated under that statute for any of the five years at issue.4 The court concludes that
Plaintiffs’ appeal does not present a valuation error correctible under ORS 311.205(1)(b)(A).
III. CONCLUSION
Upon careful consideration, the court concludes that the subject property’s MAV may not
be corrected under either ORS 311.234 or ORS 311.205 for the 2020-21 through 2024-25 tax
years. Now, therefore,
IT IS THE DECISION OF THIS COURT that Plaintiffs’ appeal is denied.
