Property Revaluation News

The Washington State Department of Revenue has approved the Assessor’s Office's  Annual Real Property Revaluation program. Annually, 1/6th of the county will be physically inspected and the whole county will be statistically revalued. The current annual physical inspection area for revaluation in 2018, for property taxes in 2019, is Cycle Area 3 (see inspection area map, quick view, or detailed view). It includes portions or all of Northeast Central Whatcom County, North of Kelly Rd, East of Hannegan Rd and includes Strandell, Everson, Nooksack, Sumas, Deming, Kendall, Maple Falls and Glacier.

There are important items that are anticipated to create questions and concerns for Whatcom County Taxpayers. The general real estate market for the majority of real property has been appreciating at an accelerating rate. The majority of assessed value changes demonstrate this activity similarly. Shifting amongst individual tax burdens, although present, is not the prevalent cause for property tax increases. (see below) 

NEW LEGISLATIVE UPDATE: The 2017 Washington State Legislature passed Engrossed House Bill (EHB) 2242 to meet the Washington State Supreme Court mandated obligation to fully fund basic education. The new law in addition to other education related requirements, makes changes which:

  • Increase property taxes imposed by the state. (see below)
  • Limit certain voter-approved property taxes imposed by school districts.
  • Facilitate state funding for certain school districts.

EHB 2242 temporarily changes the state property tax levy from a budget-based system to a frozen rate-based system and increases the tax rate to a new level for 4 consecutive years. In the first year, Whatcom County's specific rate for State taxes due in 2018 will increase from 
$ 2.23 to approximately $ 3.20 per thousand dollars of assessed value. This will provide an approximate 55% increase (except Senior Citizen and Disabled Person exemption program participants) in the State Tax Dollar portion of your tax bill. For additional information on this new law:
