How Much Tax Will I Pay Selling My Business?

The short answer

There is no single tax rate on the sale of a business. The bill is a stack of smaller numbers driven by entity type, the structure of the deal (asset vs stock), the basisyou’ve built up in what’s being sold, the state where the gain is sourced, and the terms — installment, earnout, rollover equity — that control the timing.

The exit tax calculator on the homepage is the fastest way to get a rough number. This article walks through what sits inside that number so you can see which levers actually move it.

Entity type sets the baseline

Your entity is the first thing that decides how a sale is taxed.

• S-corp: Generally a single layer of tax at the shareholder level. In an asset sale, the gain flows through to the owners and keeps its character (capital vs ordinary) based on the assets sold.
• Partnership / LLC taxed as partnership:Similar single-layer treatment, but §751 “hot assets” can convert part of what looks like a capital gain into ordinary income.
• C-corp: Two layers of tax on an asset sale — at the corporate level and again when the proceeds are distributed. Qualifying C-corp stock may be eligible for the §1202 QSBS exclusion at sale, which changes the math significantly.

Asset sale vs stock sale

Buyers usually want asset sales; sellers usually want stock sales. Asset sales produce ordinary-income recapture on depreciated assets; stock sales generally produce long-term capital gain on the equity (and leave historic liabilities with the buyer, subject to indemnification).

Two otherwise identical deals can produce materially different after-tax outcomes based on structure alone. Our asset vs stock sale explainer walks through the mechanics.

Goodwill and allocation

Within an asset sale, how the price is allocated across equipment, inventory, non-compete, and goodwill drives the tax character of the proceeds. Personal goodwill, where it applies and is supportable, can produce capital-gain treatment outside the corporate tax net. The allocation is reported on Form 8594 by both sides and should match.

The goodwill allocation guide covers this in more depth.

State and residency

California taxes a business sale at ordinary rates and does not offer a preferential capital-gains rate. Moving states shortly before a sale raises residency questions the state actively audits. Other states vary — some have no income tax, some source gain to where the business operates, some have their own pass-through entity tax (PTET) considerations.

See the California business sale tax article for more detail.

Installment, earnouts, and rollover equity

Deferred compensation can spread the tax across years and smooth the bracket — at the cost of post-close risk. Rollover equity can defer part of the gain entirely, depending on structure, but ties a portion of proceeds to the buyer’s future performance.

None of these are one-size-fits-all. They’re modeled inside the overall deal — not bolted on at the end.

The honest answer for most owners

The all-in effective rate on a typical California asset sale — federal long-term capital gain, depreciation recapture, net investment income tax, and California ordinary-rate state tax — often lands in the 25–35% range of the gain, before any planning. Planning moves measured in multiple points of that number are common when the work starts 18–36 months before close.

What to do with the number

Start with the exit calculator for a rough figure. If the number is within range of what actually matters to you, the next step is a planning conversation — ideally well before an LOI is on the table, so the decisions that move the biggest percentage of that number still have leverage.
