Contra Costa County, California
Contra Costa County anchors the northern East Bay of the San Francisco Bay Area. Here's what actually comes out of your pocket, and why.
What you pay
- Property tax — about 1.10% of assessed value. The floor is the 1% Proposition 13 general levy; voter-approved bonds add a little more depending on where in the county you are.
- Sales tax — about 8.75% combined (California's 7.25% base plus a ~1.5% local district rate). A few cities run higher.
- Income tax — California's progressive state brackets, stacked on federal.
Property tax, specifically (Proposition 13)
Your assessed value is set at your purchase price and can rise at most 2% per year — it does not track the market upward. It only resets on a change of ownership or new construction.
The flip side matters when prices fall: under Proposition 8, if your home's market value drops below its factored assessed value, you can request a temporary reduction — a lower assessment means a lower tax bill. That's the opening LegibleTax helps recent buyers find and file.
