California is the most expensive state in the country to sell a business in, and also one of the most procedural. I have talked with Bay Area founders who built their exit math on federal capital gains rates alone and then discovered the state would take up to another 13.3%. I have also watched restaurant sales in Los Angeles stretch out for weeks over notices and clearances that a seller in Texas would never have to think about.
This guide covers what is unique to selling in California: how the state taxes your gain, the bulk sale notice rules, sales tax clearance and successor liability, broker licensing, and how the market differs from San Diego to Sacramento. For the general process, see my guide on how to sell a business.
Short answer: how do you sell a business in California?
Follow the standard process (valuation, preparation, confidential marketing, due diligence and closing), then plan for four California-specific items. The state taxes capital gains as ordinary income, at rates up to 12.3% plus a 1% surcharge on income over $1 million. Many asset sales require a bulk sale notice at least 12 business days before closing. Buyers will want a sales tax clearance from the California Department of Tax and Fee Administration (CDTFA) to avoid successor liability. And anyone brokering the sale must hold a California real estate license.

California tax on the sale of your business
California does not give capital gains a lower rate. Your gain is added to your other income and taxed on the regular brackets, which top out at 12.3%, according to TaxAct’s summary of California brackets. The Mental Health Services Tax adds 1% on taxable income above $1 million, bringing the top rate to 13.3%. Because most business sales push sellers well into the top brackets in the year of closing, the state bill can rival a large share of the federal one.
| Taxable gain (single filer, no other income) | Approximate California income tax |
|---|---|
| $500,000 | About $45,000 |
| $1,000,000 | About $105,000 |
| $3,000,000 | About $370,000 |
| $5,000,000 | About $635,000 |
Rough illustration using recent California brackets. Actual tax depends on filing status, other income, deductions, deal structure and current-year brackets. Work with a California CPA.
A San Jose software founder I spoke with had modeled his after-tax proceeds carefully, except for the state line. The California bill on his gain came in at well over six figures more than he expected. Structure can help: installment sales spread the gain across tax years, purchase price allocation affects how much is ordinary income versus capital gain, and qualified small business stock rules can matter for C corporations. One caution: the Franchise Tax Board looks closely at sellers who move out of state right before a sale, so any residency change needs real substance and good timing.
California’s bulk sale notice
California is one of the few states that still has a bulk sales law. Under Commercial Code section 6105, a covered bulk sale requires a notice given at least 12 business days before the sale. The notice must be recorded with the county recorder, published in a newspaper of general circulation, and delivered to the county tax collector. It identifies the seller and buyer, describes the assets, and states the expected sale date. Certain sales must also run through an escrow that pays the seller’s creditors.
In practice, your escrow company or attorney handles the notice, but you need to build the time into your schedule. An LA restaurant sale I followed slipped almost a month because the notice was published late and the liquor license transfer, which runs through its own state process and escrow, could not close until the bulk sale escrow did.
Sales tax clearance and successor liability
If you sell tangible goods or hold a seller’s permit, California makes your unpaid sales and use tax a buyer’s problem too. Under CDTFA Regulation 1702, a buyer of a business or its stock of goods must withhold enough of the purchase price to cover the seller’s unpaid tax, interest and penalties, unless the state issues a tax clearance certificate.
| Rule | What it means for your sale |
|---|---|
| Buyer must withhold | Without a clearance, the buyer can be liable for your unpaid sales tax up to the purchase price |
| Tax clearance certificate | The buyer requests it in writing; it issues once your tax is paid or secured |
| 60-day release | If the state neither issues a certificate nor sends a notice of amount due within 60 days of the request, sale date or records being made available (whichever is latest), the buyer is released |
| Three-year window | The state has up to three years after written notice of the purchase to assert successor liability |
| Each location counts | Each business location is treated separately, so partial purchases can still create liability |
Expect the buyer’s escrow to hold back funds until clearance arrives. Asking for it early, and making sure your sales tax filings are current before you go to market, keeps that holdback small or eliminates it.
California requires licensed business brokers
California treats brokering the sale of a business opportunity as real estate activity, so brokers must hold a California real estate license under Business and Professions Code section 10130. The consequences of ignoring that are real: as the Daily Journal reported, the Ninth Circuit voided an unlicensed broker’s fee agreement in 2023 and refused to award compensation for the work performed. Check the license of anyone you are paying to sell your company.
Selling a business in California’s major markets
| Region | What shapes local deals |
|---|---|
| Los Angeles | The largest and most diverse buyer pool in the state, with heavy demand for service, healthcare, e-commerce and food businesses; high rents and labor costs scrutinized |
| Orange County and the Inland Empire | Affluent buyers in Orange County; logistics, construction and home services demand in the Inland Empire |
| San Diego | Active market for healthcare, defense-related, biotech services and tourism businesses |
| San Francisco Bay Area and Silicon Valley | Tech-enabled and software businesses attract strategic and private equity buyers; main street businesses face the highest costs in the state |
| Sacramento | Government-adjacent services, construction and trades, and a growing population from Bay Area relocation |
| Central Valley (Fresno, Bakersfield, Stockton) | Agriculture-related, transportation and trades businesses; smaller buyer pool and lower multiples |
Online and tech businesses are a California specialty. If yours is internet-based, my Website Closers review covers a broker focused on larger online companies, and my Empire Flippers review covers a curated marketplace for smaller ones. Trades businesses remain highly sought after statewide; my plumbing business valuation guide shows how buyers price a typical service contractor.
Most main street buyers use SBA or bank financing. My roundup of California business lenders shows the kinds of lenders your buyer may work with.
California-specific seller checklist
- Model California tax on your gain at ordinary income rates, and review installment sale and allocation options with a CPA before you sign a letter of intent.
- Build the bulk sale notice into your timeline, at least 12 business days before closing, if your sale is covered.
- Bring your sales tax filings current and have the buyer request a CDTFA tax clearance certificate early.
- Verify your broker’s California real estate license.
- Plan license transfers, especially alcoholic beverage licenses, which follow their own state process and escrow.
- Close out employer accounts with the state’s employment tax agency and settle final payroll obligations.
- Get residency advice before any move out of state that is timed around the sale.
Choosing a broker in California
Selling a California company with $1M+ in revenue?
Earned Exits works with established companies doing $1M to $40M in revenue and works on a success fee. Their free valuation is a no-cost way to see what your business is worth before you deal with taxes, notices and clearances.
If you are still a few years away from selling, start with my notes on choosing the best exit strategy, which matters even more in a high-tax state.
My take
Selling a business in California takes more planning than almost anywhere else. The state’s tax bite is large enough that structure and timing decisions can be worth six or seven figures, and the bulk sale and sales tax clearance rules add weeks to a careless timeline. Bring a California CPA and an experienced escrow officer in early, hire a licensed broker, and you can still come out with a great result. Selling in another state?
