Property Valuation and Appeals Process

Yamhill County Appraisals,
Request for Review and Appeals:
Information and Links


The process of identifying taxable property and assigning a value to property is termed appraisal. County appraisers appraise most property in Yamhill County using the mass appraisal method. The Oregon Department of Revenue (ODOR) appraises certain large industrial sites and utility properties. The County Assessor prepares the county's assessment roll, which is a listing of all taxable property, as of January 1 of each year.
Utility property is placed on a statewide assessment roll. The ODOR allocates utility values to the county rolls prior to the preparation of tax statements.
Property subject to taxation includes all privately owned real property (e.g., land, buildings, fixed machinery and equipment), manufactured homes, and personal property used in a business. There is no property tax on household furnishings; personal belongings; automobiles; crops; orchards. Business inventories or certain intangible properties are assessed by the Department of Revenue.
A business owning or possessing business personal property must file a Confidential Personal Property Return (form 150-553-004) with the County Assessor in the county where the property is located by March 15 (no late filing extension is allowed). If the Assessor determines that the total value of the business's personal property in the county is less than $16,500, the Assessor will cancel the assessment. This amount can change each year –if you have any questions as to the cancellation amount, please contact the Assessor’s Office. A personal property return is still required even if the valuation is below the threshold. The assessment cancellation is not applicable to personal property manufactured homes.
Most property used for religious, charitable, benevolent, and governmental purposes is exempt; an exemption application may need to be filed however. Having an income tax exempt 501(c)(3) status determination from the IRS does not automatically make a property exempt from paying property taxes.  Although an exemption negates paying property taxes on the portion of the property that is used for exempt purposes, the organization is still responsible for any special assessments. Reductions in assessments are also granted for certain types of property such as farmland, forestland, and historical buildings. Properties owned by disabled veterans may also be given reduced assessments.
Questioning your property value?
Property owners are encouraged to contact the Assessor’s office first instead of filing an appeal directly. We welcome the opportunity to explain your value and review your account. A property owner may request a Request for Review after receiving a tax bill. You will be required to provide market evidence to support why your Real Market Value (RMV) on your property is incorrect (see “Supporting Documentation Is” section below). Your evidence must reflect the value of the property as it existed on January 1, 2017.  An appraiser will review your supporting documents; verify components/inventory of your property; check for data errors; and review sales/listing activity in your area to determine whether a value adjustment is in order.
A significant reduction in RMV may be required to reduce your taxes. To review your Maximum Assessed Value, a "new" change to the property must have occurred. The request for review process may be requested through December 16th; after that date, you should file an appeal with the Board of Property Tax Appeals.  The Assessor requests that property owners not wait until the cut-off date to file a request for review.  Adequate time is needed to review the request and submitted evidence to determine if a value change is warranted. If the review results in a RMV reduction, tax corrections need to be processed by December 31st per ORS 308.242.
General Property Tax Appeal Information
Whether or not the Assessor’s Office completes a request for review on your property, you can file a formal Board of Property Tax Appeal (BoPTA) petition. Petitions to the Board may be filed after tax bills are received in late October through the December 31st filing deadline. (If December 31st falls on a legal holiday or weekend, the filing deadline moves to the next business day.) The BoPTA appeal forms are available online via the Yamhill County Clerk’s website.
A BoPTA appeal is limited to the current tax year values. In some cases, you may be able to appeal the Maximum Assessed Value (MAV), Specially Assessed Value (SAV) and Assessed Value (AV) of your property. 
The Board of Property Tax Appeals can also hear appeals of penalties assessed for the late filing of real and personal property returns. The Board has jurisdiction to waive all or a portion of a penalty if the petitioner can prove there was good and sufficient cause for the late filing or for first-time non-filers.
 PLEASE NOTE: A reduction in the Real Market Value may NOT change your tax bill. This depends on whether:

  • The RMV is reduced below the Assessed Value as shown on your tax statement, or
  •  If the RMV is reduced enough to reflect the lesser of tax between the Measure 5 calculation and the Measure 50 calculation.

Generally, to be successful in your appeal, you must provide evidence to support your opinion of the market value of your property on January 1, 2017, the date the assessor used to establish the real market value of your property. Page 2 of the BoPTA petition states "Provide enough information to support the value(s) you are requesting. Be specific." A common mistake taxpayers or their representatives make when filing a petition is that the only statement made is that their value is too high and supply no supporting documentation. Without this evidence the appraiser and the Board cannot adequately review the property value.
A key factor to remember throughout this process is the difference between what IS and what is NOT supporting documentation, as this evidence might be used to convince the Board the value of your property should be reduced to the value you are requesting. 

1. Supporting documentation IS:

1.   Documentation of a recent arm's - length sale of the property.
2.   Sales of homes similar in size, quality, location, and close to the January 1st assessment date.
3.   A fee appraisal that establishes market value using sales of similar properties as of the January 1st assessment date. (Note: most fee appraisals are requested for purchase or refinance purposes and not to establish ad valorem real market values.)
4.   A detailed market analysis from a licensed real estate agent/broker showing sales of similar properties as of the January 1st assessment date.
5.   Cost of new construction that took place close to January 1 of the assessment year and was performed by a professional contractor.
6.   Report or written estimates/receipts from a licensed contractor on the cost to fix major repairs. Remember cost does not necessarily equal market value.
7.   Proof that the property has been listed for sale on the open market for a reasonable time period below the real market value on the tax roll.
8.   For commercial property, provide documentation of income and expense information and/or a comparable sales analysis.

Note: Per ORS 309.200 sales between January 1 and December 31 of each year will be utilized for the ratio study. 

  2. Supporting Documentation is NOT:

1.   Statistical reports and analysis from the state, county, magazines, newspapers, universities, or other organizations associated with the real estate industry.
2.   Old listings.
3.   Sales from outside your market area.
4.   A comparison of your real market value to your neighbors.
5.   A comparison of your assessed value to your neighbors.
6.   A comparison of your taxes to your neighbors.

The owner(s) can sign the petition to the Board and represent themselves at the hearing, or authorize certain other persons to sign the petition and represent them. Those persons who can be authorized to sign a petition are explained on the petition form.
Completed BoPTA petitions are filed in the office of the County Clerk in the county where the property is located. Petitions are not to be dropped off at or mailed to the County Assessor’s office.At this time, there is no fee for filing an appeal with the Board of Property Tax Appeals.
BoPTA hearings can be scheduled between the first Monday in February and April 15; in Yamhill County, hearings are typically completed by the end of March. The Clerk of the Board will give written notice to the petitioner of the time and place to appear at least five days prior to the hearing.  Board hearings are informal, and the property owner is not required to appear or have a representative present.
The Board will consider the evidence from the property owner or representative and the County Assessor. The Board will make a decision whether or not the property owner or rep is there. The Clerk of the Board notifies the property owner or their representative in writing of the Board’s decision. If a property tax representative is hired, it is their responsibility to notify the property owner of the decision, not the County Clerk or the Assessor’s office.  Any evidence submitted to the Board will not be given back.
Owners of industrial property appraised by the Oregon Department of Revenue must file their appeals directly with the Magistrate Division of the Oregon Tax Court rather than with the Board of Property Tax Appeals. There is a fee for filing an appeal with the Magistrate Division. The deadline for filing an appeal with the Magistrate Division is also December 31 (if December 31 falls on a legal holiday or weekend, the filing deadline moves to the next business day).
If a property owner is not satisfied with the Board's decision regarding property value, the property owner may appeal to the Magistrate Division of the Oregon Tax Court. Magistrate decisions can be appealed to the Regular Division of the Tax Court. Decisions of the Regular Division of the Tax Court can be appealed to the Oregon Supreme Court. Complaints to the Oregon Tax Court must be filed within 30 days (not one month), of the date that the board's order is mailed. A filing fee of is charged at this level of the appeal process.
