Calculating Contra Costa County Property Tax

The calculation of property tax in Contra Costa County is based on the assessed value of your property and the current tax rate. The assessed value is determined by the Contra Costa County Assessor’s Office, taking into account factors such as the property’s location, size, and improvements. The tax rate, on the other hand, is determined by various local agencies and can vary from year to year.

Payment Options and Deadlines

Property tax payments in Contra Costa County can be made in two installments. The first installment is due on November 1st, while the second installment is due on February 1st of the following year. It is important to note that late payments may incur penalties and interest charges, so it is advisable to pay on time to avoid any additional fees.

Exemptions and Deductions

Homeowner’s Exemption

If you own and occupy your property as your principal place of residence, you may be eligible for a homeowner’s exemption. This exemption reduces the assessed value of your property by a certain amount, resulting in lower property taxes. However, it is important to apply for this exemption with the Contra Costa County Assessor’s Office.

Senior and Disabled Exemptions

Seniors and disabled individuals may be eligible for additional exemptions. The Senior Exemption provides a further reduction in property taxes for individuals aged 65 or older, while the Disabled Exemption offers relief for those with qualifying disabilities. To claim these exemptions, you must meet specific criteria and submit the necessary documentation.

If you believe that your property has been over-assessed, you have the right to appeal the assessment. The assessment appeal process involves submitting an application to the Contra Costa County Assessment Appeals Board within a specified timeframe. It is important to provide supporting evidence and documentation to strengthen your case.
