Note up front: I am a REALTOR, not a tax advisor. Use the figures below to budget, and confirm your exact bill with the Alameda County Assessor or a tax professional.
If you are buying in Oakland, your ongoing annual property tax is separate from the one-time transfer tax charged when a property changes hands. This post covers the yearly bill.
The Prop 13 base. California's Proposition 13 sets a base ad valorem rate of 1 percent of a property's assessed value. For a new buyer, assessed value is generally the purchase price, and it can rise no more than 2 percent per year while you own the home unless you make major improvements. That base rate is the floor, not the full bill.
Voter-approved add-ons. On top of the 1 percent, Oakland and Alameda County property owners pay for voter-approved bonds, largely school and infrastructure measures. These push the effective rate above 1 percent. Across Alameda County the effective rate commonly lands in the range of roughly 1.2 to 1.4 percent of assessed value, and parts of Oakland run higher because of local bond debt. One market tracker reported a countywide average bill near $7,600, though your number depends entirely on your purchase price and parcel.
Parcel taxes and special assessments. Beyond the ad valorem taxes, many bills include flat parcel taxes and special assessments (schools, libraries, mosquito abatement, and similar line items). These are fixed dollar amounts rather than a percentage, so they weigh more heavily on lower-priced properties.
A budgeting rule of thumb. For a quick estimate in Oakland, multiply your expected purchase price by about 1.25 to 1.4 percent, then add a few hundred dollars for parcel taxes. On a $850,000 home, that is roughly $10,600 to $11,900 a year, plus fixed assessments. Treat this as a planning range, not a quote, and verify the specific parcel before you rely on it.
Remember that Oakland also charges a separate one-time real property transfer tax at the time of sale, which is a different topic from this annual bill.

Oakland property taxes start with Prop 13's 1 percent base rate on assessed value, and once voter-approved bonds and assessments are added, the effective rate typically runs around 1.2 to 1.4 percent, so many buyers budget roughly 1.25 to 1.4 percent of the purchase price per year.
