When do supplemental tax bills need to be paid in San Francisco?

When your supplemental tax bill is due in San Francisco depends on when they are mailed by the Office of the Treasurer & Tax Collector. If the bill is mailed between July 1 and October 30, the taxes will become delinquent at 5 pm on December 10 for the first installment and 5 pm on April 10 for the second installment.

If the supplemental tax bill is mailed between November 1 and June 30, the delinquency dates will be printed on the bill. The first installment will become delinquent at 5 pm on the last day of the month after the month bill was mailed. The second installment is delinquent at 5 pm fourth months after the delinquency date of the first installment.

Penalties of 10% are added to any installment, which is not paid on time, and an additional $45 charge is added to a late second installment.
