Final Return for Taxpayers Ceasing Business
If certain gross receipts / payroll expense tax thresholds were met, you may be required to file an Annual Business Tax Final Return for the year in which business ceased in San Francisco.
Submit a request to waive your penalties or get a refund. Our office will review requests in accordance with the California Revenue & Taxation Code and the San Francisco Business and Tax Regulation Code. We encourage taxpayers to provide any documentation supporting the requests.
All taxpayers are required to enter a valid online pin (PIN) in addition to their Business Account Number (BAN) and last four digits of their Federal Tax Identification Number to access our online payment and filing applications.

You will be unable to file any taxes without your PIN. If you do not file by the deadline, you will be subject to penalties, interest and fees.
