Selling a Bay Area business without losing a step
I owned a business and sold it before I ever represented a seller, so I know what that decision feels like from the inside. Today I help owners from San Francisco to San Jose and up through the North Bay put a fair number on their business, prepare it for a buyer’s questions and stay with the deal until it closes, all by phone and video.
The nine county Bay Area at a glance
Roughly 7.6 million people live in the nine Bay Area counties, and together they hold more than 366,000 private business locations. Their combined output came to about $1.33 trillion in 2024.
| Measure | Figure | Period |
|---|---|---|
| Residents, nine counties | 7,619,201 | 2025 |
| Private business establishments, nine counties | 366,626 | First quarter 2026 |
| Gross domestic product, nine counties | About $1.33 trillion | 2024 |
| Nonfarm jobs (San Francisco, San Jose, Santa Rosa, Vallejo and Napa metro areas) | 4,030,300 | September 2026, preliminary |
| Counties and cities | 9 counties, 101 cities | Current |
| Port of Oakland container volume | 2,253,976 twenty foot equivalent units | 2025 |
With 101 cities, the local rules a buyer inherits can change at a city line, so a shop in Oakland and a similar one in San Jose may carry very different tax bills into a sale.
Where Bay Area paychecks come from
Professional services and health care each employ well over 700,000 people here, and trade, government and hospitality follow. Technology shows up in both the professional services and information rows. Where I have a guide to selling that kind of business, it is linked in the last column.

|---|---|---|
| Professional and business services | 790,000 | Professional services |
| Education and health services | 758,100 | Health care practices, home care |
| Trade, transportation and utilities | 524,800 | Retail and ecommerce, logistics |
| Government | 502,000 | |
| Leisure and hospitality | 420,100 | Food and beverage, sports and recreation |
| Manufacturing | 304,700 | Manufacturing |
| Information | 227,600 | |

Local business taxes buyers will check
Early in diligence a buyer will ask what the business sends to City Hall every year and whether the account is in good standing. In the Bay Area the answer depends heavily on which city you are in, because some tax receipts and others tax headcount.
| Where the business is | How the local tax or license works |
|---|---|
| San FranciscoBusiness registration | Anyone doing business in the city registers with the Treasurer and renews every year by the last day of February. For 2026 to 2027 the fee is tiered by San Francisco gross receipts, from $55 for receipts up to $100,000 to $60,000 for the largest businesses, plus a $4 state fee. |
| San FranciscoGross receipts tax | Proposition M rates took effect January 1, 2025. Starting with tax year 2025, most businesses with San Francisco gross receipts of $5 million or less do not file the gross receipts tax return. Above that, the rate depends on the business activity. |
| OaklandBusiness tax certificate | Anyone conducting business or owning rental property in Oakland files and pays every year, including businesses based elsewhere that work in the city. Since January 1, 2023, Measure T has set tiered gross receipts rates by business class that rise as receipts grow, and small businesses are no longer exempt. Rental income is taxed at $13.95 per $1,000. |
| San JoseBusiness tax | The tax is set by headcount. On the city’s published schedule, effective July 1, 2024, the base is $216.35 for one or two employees, with an added amount for each employee above that and an annual cap. A $4 state fee applies, and commercial landlords pay $0.03 per square foot plus the base tax. |
| Santa ClaraBusiness tax license | Also employee based. From July 1, 2026, a business located in the city pays $47.37 per employee, with a cap of $368,436 a year. Out of town businesses pay less if they work in the city fewer days. |
| BerkeleyBusiness license tax | A rate per $1,000 of gross receipts that depends on the classification, such as $1.20 for retail, $1.80 for business and personal services and $3.60 for professionals, with a $51 minimum in each of those classes. |
Rates and business categories change on each city’s own schedule, so have your CPA check the exact figures ahead of closing. For statewide items, including CDTFA and EDD tax clearances, bulk sale notices and liquor license transfers, see my California page.
From the North Bay to Silicon Valley
The buyers, landlords and value drivers for a Napa hospitality business look nothing like those for a San Jose tech services firm. Here is a short look at each part of the region, using public data.
San Francisco
San Francisco County had 826,079 residents in 2025 and 69,827 private business establishments in the first quarter of 2026. Its economy produced about $268.3 billion in 2024, second only to Santa Clara County among the nine.

Alameda and Contra Costa counties together counted 119,221 private establishments in the first quarter of 2026. The Port of Oakland handled 2,253,976 twenty foot equivalent units of cargo in 2025, split almost evenly between imports and exports, and says it supports more than 98,000 regional jobs.

Santa Clara County is the most populous of the nine, with 1,914,391 residents in 2025, and its $438.5 billion in 2024 output is the largest too. The San Jose metro had 131,100 manufacturing jobs and 97,000 information jobs in September 2026.

I have sat in the seller's chair.
My own Los Angeles senior care agency came first: I owned it, ran it and sold it, and only then started advising other owners. Going through that sale showed me what buyers look for, where a deal can stall and what it takes to step away from something you built. Bay Area owners get that view from our very first conversation.

Buyers pay closer attention to a business with clean records and a plan on paper. These groups can help owners build both well ahead of a sale.
Bay Area SBDCs
The California SBDC network lists centers for San Francisco, the East Bay, San Mateo, Silicon Valley, Marin and Sonoma, plus a joint Solano Napa center. Advising is confidential and offered at no cost.

Brief answers to the questions that tend to come up on a first call.
Which city business tax will a buyer look at?
Whichever city your business operates in. San Francisco and Oakland work from gross receipts, San Jose and Santa Clara count employees, and Berkeley applies a rate per $1,000 of receipts that depends on your type of business. A buyer will ask for proof that your account is current.
Can we handle the whole sale remotely?
Yes. From our first conversation until the deal closes, I work with Bay Area owners by phone and video. It keeps things confidential and lets you keep running the business while we prepare the sale.
Will my company owe the San Francisco gross receipts tax?
Under Proposition M, most businesses with San Francisco gross receipts of $5 million or less do not file the gross receipts tax return, starting with tax year 2025. They still renew their business registration every year. Above that level, rates depend on the business activity, so your CPA should run the numbers.
What happens to my San Francisco business registration when I sell?
The buyer registers in their own right. The Treasurer's application asks whether it is a change of ownership of an existing business and asks for the prior account number. You tell the city when you stop operating, and closing the account does not erase any balance still owed, so settle it before closing.
Is there free help for getting ready to sell?
The California SBDC network has centers for San Francisco, the East Bay, San Mateo, Silicon Valley, Marin and Sonoma, plus a joint Solano Napa center, with advising that is confidential and free. The SBA San Francisco District Office covers all nine Bay Area counties.
