Selling a business in San Francisco is not like selling anywhere else. You are operating in one of the most expensive, most regulated, and most deal-savvy markets in the world. Tech buyers expect sophisticated financials. California will take a significant cut of your proceeds. And the exit landscape here, whether you are a software company, a restaurant, or a service firm, has its own set of rules.
This guide walks you through what to expect: taxes, valuation, finding the right broker, and structuring a deal that actually closes.
California Taxes on a Business Sale
The first thing every San Francisco seller needs to understand: California taxes capital gains as ordinary income. There is no preferential long-term capital gains rate at the state level. That means if you are in the top bracket, you are looking at up to 13.3% in state taxes on top of federal rates.
On a $2 million sale, California alone could take $200,000 or more. Work with a CPA who specializes in California business exits before you set your asking price. Strategies like installment sales, Qualified Opportunity Zone reinvestment, or Charitable Remainder Trusts can reduce the hit, but only if structured in advance.
The California Franchise Tax Board (FTB) is aggressive about taxing gains sourced in California, even if you have relocated to a no-income-tax state. If you lived and operated in SF during the years the value was built, expect to owe California taxes regardless of where you reside at closing.
What Is Your Business Worth in the SF Market?
San Francisco valuation depends heavily on what kind of business you are selling.
Tech and SaaS Businesses
Revenue multiples dominate. SaaS companies with strong ARR and low churn regularly trade at 4x to 8x annual recurring revenue, sometimes higher in hot categories. Strategic acqui-hires from larger tech companies are common, where the buyer is primarily paying for the team and technology, not the revenue.
Service and Professional Firms
These typically trade at 2x to 4x seller’s discretionary earnings (SDE). High client concentration or owner-dependency will compress the multiple. Document your processes and reduce owner involvement before going to market.
Brick-and-Mortar and Hospitality
SF’s high rents and labor costs make margins thin. Restaurant and retail businesses often trade at 1x to 2x SDE. Lease terms are critical: a buyer inheriting a lease with 18 months left at above-market rent will discount the price accordingly.
Finding a Business Broker in San Francisco
For deals under $5 million, a certified business broker (CBB or CBI credential) is usually the right move. They handle marketing, qualify buyers, and manage the negotiation process. Expect a success fee of 8% to 12% on smaller deals.
For deals over $5 million, an M&A advisor or boutique investment bank is more appropriate. They work on retainer plus a success fee and have relationships with strategic and financial buyers that a general broker will not.
Vet any broker carefully. Ask how many SF businesses they have sold in your industry in the last 12 months, request references from sellers (not buyers), and confirm they will maintain confidentiality. A broker who lists your business publicly before qualifying buyers is a liability.
Preparing Your Business to Sell
Buyers in San Francisco, especially those backed by PE firms or coming from a corporate background, expect clean financials. Sloppy books are a deal-killer here more than anywhere else.
- Three years of tax returns and P&L statements — reconciled and verifiable
- Clean separation of personal and business expenses — document every add-back clearly
- Customer concentration analysis — if one client represents more than 20% of revenue, disclose it early
- Employee agreements and IP assignments — especially critical for tech businesses
- Lease status and transfer rights — confirm your landlord will approve an assignment before you go to market
Getting a quality-of-earnings (QoE) report from an independent accounting firm is increasingly expected at the $1M+ level. It adds legitimacy and speeds up due diligence.
The Sale Process: What to Expect
A typical SF business sale takes four to nine months from going to market to closing. The process generally looks like this:
- Valuation and preparation (4 to 8 weeks) — clean financials, build a confidential information memorandum (CIM), set asking price
- Marketing and buyer outreach (4 to 12 weeks) — broker markets confidentially, NDAs signed before any details shared
- Offers and LOI — letter of intent sets price, structure, and exclusivity period (typically 60 to 90 days)
- Due diligence (30 to 60 days) — buyer verifies everything; this is where deals fall apart; be prepared
- Closing — asset purchase agreement or stock purchase agreement executed, funds transfer, transition period begins
Most SF deals include a seller transition period of 30 to 90 days. For tech businesses, this is often extended to ensure knowledge transfer. Negotiate the scope and compensation for this period upfront.
Asset Sale vs. Stock Sale
Buyers almost always prefer asset sales because it limits their liability exposure and allows them to step up the tax basis of acquired assets. Sellers usually prefer stock sales because it simplifies taxes and transfers all liabilities to the buyer.
In California, the distinction matters for sales tax on inventory, employment tax implications, and transfer of licenses. Your attorney and CPA need to align on the right structure before you sign an LOI.
Get the Right Team Around You
Selling a San Francisco business requires a team: a business broker or M&A advisor, a California CPA with exit experience, and a business attorney familiar with California deal structures. Cutting corners on any of these is how sellers leave significant money on the table or get stuck in post-closing disputes.
The California Franchise Tax Board and SBA’s closing and selling guidance are good starting points for understanding your obligations. For legal structure, LegalZoom can help with the foundational documents.
