Mount Vernon property inspections to begin in August, 2020
All properties in the Mount Vernon School District are being revalued for the 2021 assessment year. Appraisers from the Assessor’s Office will inspect all commercial, farm and residential properties in the district. With the exception of properties issued building permits in the six years since, the last inspections for this area occurred in 2015.

In consideration of the COVID 19 environment, the majority of inspections will be limited to what can be observed from the street. Unless appraisers have questions about the property, our policy of announcing our presence by knocking on the front door is suspended. For properties that need verification of characteristics, we will knock then retreat to a safe distance. In those instances there will be a brief exterior walk-around of structures. In all cases new photos are taken. Appraisers will have face coverings, gloves and wear distinctive vests with Skagit County on the back and carry county identification cards. They drive white vehicles with the Skagit County emblem on the side. If you have questions or concerns, please contact the Assessor’s Office at 360 416-1780.

Corona Virus Response Notice
Beginning Tuesday, March 17, the Assessor customer service counter will be closed to the public in consideration of public safety and the risk of exposure to the novel coronavirus. Many of those we serve are participants of the senior citizen and disabled property tax exemption program and we take this action to prevent unnecessary risk to them.

The closure period is indefinite but we will reopen as soon as the threat is diminished. All senior exemption outreach events are cancelled for 2020. For those wishing to apply for or renew the exemption may call our office for information or instructions. If you have circumstances that require personal interaction we can set an appointment to meet in our conference room. For all other matters, please call our office to arrange a solution for your business needs. We apologize for the inconvenience but believe this is a required step for the safety of our community.

State School Levy and Local School Levies

Our local schools have two primary sources of financial support. The State School Levy is assessed to all property owners in the state and those funds fall under the jurisdiction of the Office of Superintendent of Public Instruction (OSPI). Local school districts receive funds through an allocation process determined by OSPI. The legislative fix to the McCleary decision to adequately fund schools was to increase the State School Levy.

About the Assessor's Office

The assessor acts as an agent for the Washington State Department of Revenue and is responsible for administering the property tax system for the county. This process involves establishing real and personal property values for distributing taxes for each tax district, as well as reviewing each tax district’s budget request to assure all legal requirements and limitations are met. The assessor also administers and monitors compliance for recipients of tax benefit programs, such as the Senior Citizen and Disabled Exemption program and the various Current Use programs for properties used for agriculture, timber and open space.
