- If you file Business Personal Property statements, notify the Assessor and file the final one
- Close health permits, the fictitious business name and state accounts separately

General information only, not legal or tax advice. City forms and thresholds change, so confirm current steps with the Office of the Treasurer and Tax Collector, your attorney and your CPA.
Why the City Needs Its Own Goodbye
San Francisco is a consolidated city and county, and it collects its own business taxes on top of the state's. Your company registered with the Treasurer and Tax Collector when it opened, and that registration renews every year.
A sale doesn't end it. In an asset sale, the buyer registers its own business. Your registration stays active, and the city keeps expecting fees and filings from it.
The city's guidance warns that accounts left open can keep generating registration fees. That is a small cost, but it attaches to a company you thought you were done with.
Most Bay Area cities run their own business tax or license programs, with their own forms and their own closure steps. Owners in Oakland or on the Peninsula deal with their own city hall, not San Francisco's.
The pattern is the same everywhere: close the city account, file whatever the final year requires, and notify the county assessor if you report business property there.
The deal closes in escrow. The company closes at City Hall, one account at a time.
Cancel the Business Registration
The Treasurer and Tax Collector handles this through its online account system and a Declaration of Closed Business. The declaration asks whether you sold the business and, if so, the new owner's account number when there is one.
The city advises updating your mailing address before you close the account, since you can't change it afterward. Notices about the old company need somewhere to go.
Any balance still owed on a closed account is moved to the city's Bureau of Delinquent Revenue for collection. Clear it first, not after.
Do You Still Owe a Gross Receipts Filing?
Possibly. San Francisco's business taxes are filed annually, based mostly on gross receipts.
The city's closure guidance says that if your payroll or receipts are above the filing thresholds, you submit a final Payroll Expense and Gross Receipts Tax filing with payment.
The declaration also has you acknowledge that the annual return for the year the business stopped is your responsibility, where it applies. The sale year still counts, even if you only owned the business for part of it.
Your CPA can tell you whether your receipts for that partial year cross the line. Ask before closing, since the answer may belong in the closing statement.
The Assessor Is a Separate Office
If your company files Business Personal Property statements, the Form 571-L, it has an account with the Office of the Assessor-Recorder. That is a different office from the Treasurer, with its own closure step.
The city's guidance says to notify the Assessor and file your final Business Personal Property statement. The Assessor has its own request to close a business account.
California values business property as of January 1, so the owner on that date typically reports the year. Settle in the purchase agreement who bears that year's bill; a daily proration is common.
Permits, Names and State Accounts
The city account is only part of the list. Most sellers also need to close or hand off these:
- Health permits, through a closure form with the Department of Public Health
- A fictitious business name, which may need an abandonment filed with the County Clerk
- The CDTFA seller's permit, closed with a final sales tax return
- The EDD payroll account, with final returns and W-2s
- A liquor license, which transfers through ABC rather than closing
The state pieces are covered in our articles on CDTFA tax clearance, EDD clearance and liquor license transfers.
What the Buyer's Attorney Will Ask For
City taxes come up in diligence more often than sellers expect. A buyer taking over a San Francisco location wants to know the business has been registered and filing, and that nothing is waiting in collections.
Have these ready: your registration certificate, recent annual business tax filings, proof of payment, and any notices from the Treasurer and Tax Collector or the Assessor in the last few years.
If you have been under the filing thresholds, say so and show the numbers. Silence on city taxes reads as a gap, even when there is nothing owed.
What Order Works Best
Before you list, pull your city account history and fix gaps. A buyer's attorney will ask about city taxes, and missing years look worse than small balances.
At closing, escrow pays known balances from your proceeds. Right after, file the final returns, cancel the registration with the new owner's details, and close the Assessor account.
Leave the legal entity itself open until any seller note, earnout or holdback has run its course. Ending the company with the Secretary of State is a separate filing, and it doesn't notify the city.
Stock Sales Skip Most of This
If the buyer purchases your company's stock, the company keeps operating with its city registration intact. There is nothing to cancel. The buyer updates the ownership details instead.
That also means your company's city tax history stays inside the business the buyer now owns. Expect the purchase agreement to put taxes from before closing on you, backed by an escrow or holdback.
