Asset Sale or Stock Sale? The Double Tax on a C Corporation
§§ 11, 331 · reviewed September 7, 2026
Compares what you keep from selling your C corporation's assets against selling its stock, and shows the price that would make the two equal. AboutLess
In plain words. A C corporation is taxed as its own person. If it sells its assets, it pays corporate tax on the profit, and when it hands the rest to you, you pay tax again on the money over what your stock cost. If you sell the stock instead, you pay once. Buyers often prefer to buy assets, because they get to depreciate what they paid. This tool takes the price, what the corporation's assets cost, what your stock cost, and your rate, and shows both routes side by side with the gap between them.
Why it matters. The first thing a buyer's letter of intent says is whether it is an asset deal or a stock deal, and the difference can be a fifth of the price. Knowing the gross-up, the higher asset price that leaves you even, is what lets you answer.
An example. A corporation sold for $5,000,000 with $1,000,000 of basis in its assets and $500,000 of stock basis, at 20 percent plus the surtax: an asset sale leaves about $3,289,000 after $840,000 of corporate tax and $871,000 at your level. A stock sale leaves $3,929,000. The double tax costs about $640,000, and an asset buyer would have to pay about $6,063,000 to make up for it.
Where it stops. It models a C corporation only, with no state tax, no election to treat a stock sale as an asset sale, no losses carried into the year, and no exclusion for qualified small business stock. An S corporation pays one level of tax and is a different calculation. Everything it leaves out.
What the buyer pays, whether for the assets or for the stock.
What the corporation's assets cost it, less depreciation. It is on the corporate balance sheet and the depreciation schedule.
What you paid or contributed for your shares. Often small in a business you founded.
The federal rate on long-term gains at your income. A sale this size usually lands at 20 percent.
- Tax at the corporate level in an asset sale
- $840,000
- 21% on the $4,000,000 gain over the corporation's basis
- Tax at your level in an asset sale
- $871,080
- 23.8% on the $4,160,000 distributed, over your stock basis
- Extra a buyer would pay to make an asset deal equal
- $1,063,291
- On top of the price, so that you keep what a stock sale leaves
The buyer wants the assets for a reason. Buying assets lets the buyer depreciate what it paid. Buying stock leaves the assets with their old, lower basis inside the corporation. That step-up is worth something to the buyer, and the gross-up is what it would cost the buyer to pay for it. Between the two figures is the room to negotiate. A buyer will also weigh the liabilities that come with the stock, which is the other reason asset deals are asked for.
This follows the federal rules for a C corporation, with the 21% corporate rate on the gain over the corporation's basis and your gains rate on what is distributed to you over your stock basis, or on the stock price over that basis. It assumes the whole price is taxed in one year, no losses carried into it, and a full liquidation after an asset sale. It leaves out state tax, an S corporation, the election that treats a stock sale of a subsidiary or an S corporation as an asset sale, and the exclusion for qualified small business stock.

This is a simplified model, not your actual tax return or plan. It only knows what you type in, leaves out rules that may apply to you, and cannot weigh the other facts and trade-offs a real decision depends on. Before you act, talk with a professional who knows your whole situation.
