This page is for informational purposes only and is not tax, legal, or financial advice. Figures describe the median homeowner household in Napa County as reported to the Census Bureau, your own bill can differ based on your parcel's assessed value, exemptions, special districts, and municipal overlays. Always consult your county assessor, tax collector, or a qualified professional before making decisions that depend on these numbers.
The rate held while the market moved
Napa County sits in the quarter of U.S. counties whose effective rate moved least over this span: 2.3% down, against a median home value that rose 30.4%.
A near-steady rate on a moving market passes that movement straight through: the median bill rose 27.3%, from $4,708 to $5,995.
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 $4,708 to $5,995. 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: 23,077 of 31,555 owner-occupied homes (73.1%) 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.
Top-quartile earnings meet a below-median rate, putting the median bill at 5.4% of median household income. Counties in this position span a wide range on the ratio above, because the dollar bill tracks home values rather than the rate.
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.
What Napa County Homeowners Actually Pay
The single largest group of Napa County homeowners, 23,077 of 31,555 owner-occupied homes (73.1%), pays $3,000 or more a year. The median is one point in this spread, not a typical bill.

- $800 to $1,499 5.2% (1,653)
- $1,500 to $1,999 3.8% (1,206)
- $2,000 to $2,999 6.8% (2,144)

These are American Community Survey 5-year estimates compared across releases that share only one sample year, which is why this page never compares consecutive releases: those overlap in four years of the same households and move mostly on sampling.

Property Tax History · QUIET · SPIKE
| Year | Median Tax (vs prior release) | Effective Rate |
|---|---|---|
| 2024 | $5,995 +2.7% | 0.69% |
| 2023 | $5,840 +5.3% | 0.70% |
| 2022 | $5,545 +10.9% | 0.70% |
| 2021 | $5,001 +6.2% | 0.73% |
| 2020 | $4,708 | 0.71% |
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.
Tax Burden
Tax Affordability Score
An effective rate well below the national average of 0.92% puts Napa County in the "Very Affordable" band for property tax burden.
How this score is calculated: a 1-10 scale derived mechanically from the ratio of this county's effective rate to the national average effective rate (0.92%) - a ratio at or below 0.5× scores 10, a ratio at or above 2.0× scores 1, with a linear scale between. It is a factual comparison of Census figures only, not a recommendation, quality rating, or endorsement of Napa County or any other county.

What tax filers report in Napa County
Of the 67,180 federal returns filed from Napa County in 2022, 10,730 (16.0% of filers) itemised and reported real estate taxes on Schedule A, averaging $10,079 each. The largest group was filers with adjusted gross income of $200k+, who accounted for 38% of the county's reporting returns.
Two things this does not say. The amount is what filers reported, recorded before the $10,000 cap on combined state and local tax deductions applies, so it is not the amount deducted. And the share is of everyone who files a return, not of homeowners: most filers now take the standard deduction, so a minority itemise at all.
