Taxes When Selling a California Business: What Owners Should Know Before the Deal
We're a buyer, not a tax firm — this page exists because owners kept asking us the same questions. Treat it as a map of what to discuss with your CPA, not as advice.
The three layers of tax on a sale
1. Federal capital gains — long-term gains (assets held over a year) are taxed at 0%, 15%, or 20% depending on income; a multimillion-dollar sale lands most of the gain at 20%. 2. Net investment income tax — an extra 3.8% for most sellers at these income levels. 3. California — the big one people miss: no preferential rate, gains stack on your other income, top rate 13.3% (with an additional payroll-tax wrinkle above ~$1M of wage income).
Where sellers win or lose: allocation
In an asset sale, you and the buyer must agree on how the price splits across equipment, inventory, goodwill, and a possible consulting or non-compete piece. Goodwill is taxed at capital-gains rates; depreciation recapture on equipment comes back at ordinary rates; consulting agreements are ordinary income plus self-employment tax. Identical prices, different allocations — after-tax differences of $100,000+ are routine. A buyer who is transparent about allocation early (we are) saves you real money.
Structures worth asking your CPA about
Installment sales spread the gain across years — useful for bracket management, but you're trusting future payments. Qualified Small Business Stock (QSBS) can exclude enormous federal gains but only for certain C-corporations — worth checking, rarely applicable to Main Street businesses. Charitable remainder trusts and opportunity-zone rollovers exist for specific situations. And if you own your building: real estate has its own toolkit (1031 exchanges, sale-leasebacks that turn the building into retirement income — we buy or lease buildings too).
The timeline that saves money
Talk to your CPA 1–2 years before selling if you can: entity cleanup, catching up depreciation strategy, and getting your books buyer-ready all pay for themselves. Already at the table? It's still not too late — allocation and structure are negotiated during the deal, and we're glad to work directly with your CPA. (Please consult your own tax professional; every situation differs.)
Frequently asked questions
How much tax will I pay when I sell my California business?
As a rough planning number: federal long-term capital gains up to 20%, plus the 3.8% net investment income tax, plus California tax — which treats capital gains as ordinary income at rates up to 13.3%. Combined, many California sellers face roughly 30–37% on the gain, though structure and allocation can change this materially. Get a CPA involved early.
Does California have a lower capital gains rate?
No — this surprises many owners. California taxes capital gains exactly like wages, at ordinary rates up to 13.3%. There is no state capital-gains discount, which is why deal structure and timing matter more here than almost anywhere else.
What's the difference between an asset sale and a stock sale for taxes?
Most small-business sales are asset sales, where the price is allocated across equipment, goodwill, and other categories — each taxed differently (goodwill at capital-gains rates; some equipment recapture at ordinary rates). How that allocation is negotiated can move your after-tax number by six figures. It's negotiated with the buyer — another reason to have your CPA at the table.
Can an installment sale reduce my taxes?
Spreading payments over years can keep you in lower brackets and defer tax — but it also means trusting the buyer's future payments. Many sellers prefer certain cash at close even at a modestly higher tax cost. Model both with your CPA before deciding.
