SF has moved their property tax deadline to May 4th. Everyone who can pay is encouraged to pay by April 10th. The City is already anticipating a budget shortfall so it needs every tax dollar. The office is still accepting payments by mail and internet. In person payments are not being accepted at this time. If you cannot pay by the new deadline, you should fill out the penalty waiver form online. San Francisco Treasurer & Tax Collector Ahsha Safai Norman Yee
