2023 Property Taxes
Aggregate King County property values increased by 21.8% in 2022, rising from $722.5 billion to $879.9 billion, but since we operate under a "budget based" property tax revenue system here in Washington State, property taxes were up, but nowhere near 21.8 percent. Aggregate property taxes in King County for 2023 rose by 6.4% or nearly $436 million, going from $6.6 billion to $7.2 billion largely due to voted measures.
The property taxes that you pay in the present year are based on the value of your property in the previous year. So, for example, your 2023 property tax bill is based on your 2022 property valuation. And your annual valuation, by state law, is calculated to be the value as of January 1 for that value year. In other words, in February 2023, you will receive a property tax bill for the value of your property as of January 1, 2022. (July 31, 2022 for remodels or new structures)
The difference between the property value increase and the property tax increase is related to how the property tax system works in Washington State. The property tax system here is often referred to as “budget based” because the mill or levy rate adjusts to property value changes so only the amount of revenue requested by the taxing districts is generated (the mill rate goes down when values go up, and up when values go down). And in Washington State, the amount of revenue taxing districts, like cities, and school and fire districts, for example, can collect from year to year can only go up by one percent unless voters approve more.
This is why voter-approved levies, and not the value of your property, is usually the primary cause of increased property taxes. Voter-approved levies are not subject to that one-percent-growth restriction. Here are a couple of examples of the budget-based phenomena in 2023:
- The highest property value increase in 2022 occurred in Sammamish where the median home value increased by 51.2%. Because of the “budget based” system, the property tax increase for 2023 payments in Sammamish is 24.0%. To accomplish this, the levy rate for Sammamish decreased by -18%, or -$1.72935 per $1,000 of property value.
- The lowest property tax increase for 2023 is in the City of Tukwila with a 1.3% increase. The median home value in Tukwila increased 16.7% in 2022, so the levy rate for this area saw a decrease of -13.2% or -$1.59891 per $1,000 of property value.
