Planning to buy a home in California? One important detail that often gets overlooked early in the process is supplemental property taxes. During a home purchase, escrow—the neutral third party that handles the transaction—ensures that property taxes are paid up to the current tax bill. However, that payment is based on the seller’s tax rate, not the buyer’s future tax obligation. Once the sale closes, the county reassesses the property at the new purchase price. From the date of closing to the next tax bill, the new owner may owe the difference between the old tax rate and the reassessed amount. This is known as a supplemental tax bill. Depending on how long the previous owner held the property, the difference can be significant. Many buyers are unaware of this until the bill arrives. Understanding how supplemental taxes work ahead of time allows buyers to plan properly and avoid surprises after closing.
