2022 State-assessed utility valuations
The following nine tables present the values determined during calendar year 2022 for utility companies that operate on an intercounty basis in Washington state. These values are determined by the Department of Revenue and apply for property taxes due and payable during 2022. The first eight tables contain information for the various types of public service companies which are subject to central assessment. The ninth is a synopsis of the same information presented on a county basis.
Department of Revenue appraisers determine the actual values – or market value – for these companies. The Department uses a formula to adjust the actual value to the equalized value – or county assessed value – so that owners of like property (real or personal) pay the same amount of tax regardless of which county the property is located in. Real property generally includes the value of land and structures; personal property comprises machinery and equipment (and, in the case of power companies, hydroelectric dams).
Prior to 2000 these tables were published in the annual Tax Statistics report. In order to make the data available earlier, as well as to save publication costs, they are now presented only on the Department's website and in both Adobe Acrobat and Microsoft Excel formats.
