Contra Costa County sales tax details The minimum combined 2025 sales tax rate for Contra Costa County, California is 8.75%. This is the total of state, county, and city sales tax rates.
Annual property tax bills are mailed every year in October to the owner of record as of January 1 of that year. If you do not receive the original bill by November 1, contact the County Tax Collector or Assessor for a duplicate bill. Note, the original bill may still have the prior owner's name on it the first year.
Copies of previous (up to 11 years) and current tax bills can be found on line by going to Account Lookup. Taxpayers may also call our office, 925-608-9500 and/or email Tax Information us to request a duplicate tax bill.
Annual Secured Property Tax Bills are prepared and mailed by the Treasurer and Tax Collector in October of each year. The first installment of your tax bill is due on November 1 and becomes delinquent by the close of business on December 10.
What items are subject to use tax. Generally, if the item would have been taxable if purchased from a California retailer, it is subject to use tax. For example, purchases of clothing, appliances, toys, books, furniture, or CDs would be subject to use tax.
The formula involves multiplying the assessed value by the Contra Costa County property tax rate, which includes the base rate of 1% plus any voter-approved local assessments and bonds. The actual property tax rate ends up being around 1.3% of a home's assessed value.
If you own and occupy your principal place of residence on January 1, you may apply for a Homeowner's Exemption that would exempt $7,000 of your home's assessed value from taxation. This would result in a savings of approximately $70 per year on your property tax bill.
In California, all properties are subject to a basic tax rate of 1% based on their assessed value. This value is set by the county assessor when the property is bought or newly built. For example, if your assessment is $500,000, the basic property tax you owe would be $5,000 annually.
Millage (mill) rate Say the mill rate in your area is 0.02 or 2%. You'd then owe $20 for every $1,000 of assessed property value. On a $300,000 house assessed at 100%, property taxes would equal $600 for the year (not including any excess levies or exemptions).
