What happens if I get more than one supplement tax bill in San Francisco?
According to the San Francisco Office of the Treasurer & Tax Collector, it is possible to receive more than one supplemental tax bill in a year depending on when the ownership change or completion of new construction occurred and when the Office of the Assessor-Recorder recorded the new value on the tax roll.
San Francisco property is assessed each January 1 for the upcoming fiscal year (July 1- June 30). Because of this, you will receive one supplemental bill if the change in property value was recorded on the tax roll between June 1 and December 31.
If the change in property value is recorded on the tax roll between January 1 and May 31, you will receive two supplemental bills.
