Informational notice

Figures describe the median homeowner household in San Juan County as reported to the Census Bureau; your parcel can differ. Not tax, legal, or financial advice: check the county assessor or a qualified professional before decisions that depend on these numbers.

A falling rate took the edge off

San Juan County's effective rate fell 14.8% across the 4-year span while its median home value rose 49.3%, leaving the median bill 27.3% higher at $4,253. That rate move is larger than the one in 62% of counties, so a good deal of the market's rise never reached the bill.

Effective rate is the published median bill divided by the published median home value, so the two multiply back to the bill exactly; the rate's movement here is derived from those two figures rather than read from the rounded published rate. Both are ACS 5-year survey estimates for the median owner-occupied household, compared across non-overlapping releases. They describe what the Census published, not a local policy, assessment, or exemption change.

How to read this county's bill

The bill here climbed steeply over 2020-2024, up 27% from $3,342 to $4,253. These ACS medians describe the reported change; they do not identify whether a levy, assessment, home value, or change in the responding households caused it.

The heaviest band is also the fullest one here: 4,643 of 7,031 owner-occupied homes (66.0%) report annual real-estate taxes above $3,000. That band has no upper edge in the source, so the county median understates the burden carried by the plurality rather than describing it.

The most forgiving PAIRING in the data, top-quartile household income with a bottom-quartile effective rate, puts the median bill at 5.0% of median household income. Home values still drive the dollar figure, which is why the ratio above varies widely among counties that share this position.

The share above is the median annual bill divided by median household income, a ratio of two county-level medians rather than a household-by-household figure.

San Juan County is an outlier inside Washington

Across the 39 Washington counties with a published rate, the average effective rate is 0.73%. San Juan County is at 0.53%, which sits 2.3 standard deviations below that average. Fewer than one county in twenty nationally is this far from its own state's centre, so a state-level average is a poor guide to what is owed here.

Standard deviations are computed across every county in the state with a published effective rate for 2024; states with fewer than five such counties are not assessed.

What San Juan County Homeowners Actually Pay

The single largest group of San Juan County homeowners, 4,643 of 7,031 owner-occupied homes (66.0%), pays $3,000 or more a year. The median is one point in this spread, not a typical bill.

Each row is a separate ACS 5-year release, and consecutive releases share four of their five survey years. The percentage beside each bill is therefore movement in the published estimate against the previous release, not a single year's tax change. The two releases largely describe the same households. For change over time, compare releases that do not overlap.
