When do I have to pay my supplemental tax bill in San Francisco?

When supplemental tax bills are due in San Francisco depends on when they are mailed to the Office of the Treasurer & Tax Collector.

If your supplemental tax bill is mailed between July 1 and October 30, your taxes will have delinquent at 5 pm on December 10 for the first installment and 5 pm on April 10 for the second installment. If your supplemental tax bill is mailed between November 1 and June 30, the delinquency dates will be printed on the bill. The first supplemental tax bill installment will become delinquent at 5 ppm on the last day of the month following when the month the bill was mailed. The second installment of your supplemental tax bill will be delinquent at 5 pm four months after the first installment was delinquent.

If you do not pay your supplemental tax bill installments on time, penalties of 10% will be added to any installment that is not paid on time. An additional $45 charge is added if you have a late second installment.
