If you're a homeowner in San Francisco, you know that December also means that half of your annual property tax payment is due by December 10th, and delinquent thereafter. The second half will be due on February 1st and delinquent on April 10th. Tax bills for new 2019 homeowners are often mailed to the previous homeowner’s name or address. Even if you have not received a tax bill, to avoid penalties it is important to initiate this payment soon!
