The average effective property tax rate in Alameda County is 0.78%, though a good rule of thumb for California homebuyers who are trying to estimate what their property taxes will be is to multiply their home’s purchase price by 1.25%. This incorporates the base rate of 1% and additional local taxes, which are usually about 0.25%. Assessed value is calculated based on market value using a base year value. A property’s original base value is its 1975-1976 market value and can be adjusted each year by no more than 2% to account for inflation.
