This page is for informational purposes only and is not tax, legal, or financial advice. Figures describe the median homeowner household in Marin 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 gave way faster than almost anywhere
Between the 2020 and 2024 releases the median home value in Marin County rose 43.1%, from $1,053,600 to $1,507,300. The effective rate fell 19.6% over the same span, a steeper move than in 81% of U.S. counties.
The median bill still rose 15.1%, to $10,001. Where the rate drops this far and the bill rises anyway, what changed is the value the rate is applied to.
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
Bills rose across 2020-2024, from $8,692 to $10,001, a gain of 15%. This is a comparison of published ACS medians, not an explanation of a particular property's assessment or tax bill.
The heaviest band is also the fullest one here: 61,013 of 66,616 owner-occupied homes (91.6%) 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 6.7% 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 Marin County Homeowners Actually Pay
The single largest group of Marin County homeowners, 61,013 of 66,616 owner-occupied homes (91.6%), pays $3,000 or more a year. The median is one point in this spread, not a typical bill.
- Less than $800 1.2% (782)
- $800 to $1,499 1.0% (664)
- $1,500 to $1,999 0.8% (536)
- $2,000 to $2,999 3.5% (2,304)
- $3,000 or more 91.6% (61,013)

How Marin County compares
Effective property tax rate (median tax ÷ median home value), ACS 2024.
Marin County's effective rate is higher than 22% of the 58 counties in California - ranking #45 of 58 for property tax burden.
Note: Census ACS top-codes median property tax at $10,000 or more, so the bill is shown as $10,001 and the effective rate above is a conservative floor - Marin County's true median tax and rate are somewhat higher.

Same rate as California, a larger bill
The effective rate here sits within 6% of the California median, yet the median bill runs 95% above it. When the rate matches and the cheque does not, the difference is in what is being taxed, not how heavily: the same percentage applied to costlier housing produces $10,001 here. That is why comparing counties on rate alone can invert the answer a homeowner actually cares about.

On Marin County's published figures (QUIET · SPIKE), a $1,507,300 median home carries a $10,001 median bill, so every 10% off an assessed value is worth about $1,000 a year at the same rate.

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 Marin 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 Marin County or any other county.

What tax filers report in Marin County
Of the 128,760 federal returns filed from Marin County in 2022, 33,480 (26.0% of filers) itemised and reported real estate taxes on Schedule A, averaging $17,587 each. The largest group was filers with adjusted gross income of $200k+, who accounted for 59% 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.
