Why the purchase price is never what you take home

Four things stand between the headline number and your bank account: debt that gets paid off at closing, professional fees, taxes, and timing. The first three reduce the total. The fourth determines when you see what's left — and on many deals, a meaningful share of the price arrives months or years after the closing table, through seller notes, escrow releases, and earnouts.

Sellers who anchor on the purchase price are often surprised twice: once by the total, and again by how much of it isn't cash at closing.

Asset sale or stock sale changes everything

In a stock or equity sale, you sell your ownership interest. The gain is generally long-term capital gain if you've held it more than a year, and the tax picture is comparatively simple.

In an asset sale, the company sells its assets and the purchase price is allocated across asset classes — equipment, inventory, real property, goodwill, non-compete agreements. Each class carries its own tax character. Buyers usually prefer asset sales because they get a stepped-up basis in the assets; sellers usually prefer stock sales for exactly the opposite reason.

The allocation is negotiated, reported by both parties, and it drives your actual tax. IRS Publication 544 covers the mechanics of gain and loss on business property dispositions.

The recapture problem

If your business owns depreciated equipment, vehicles, or similar property, part of your gain isn't capital gain at all. Under Section 1245, depreciation you claimed is recaptured as ordinary income when the property is sold — taxed at your regular rates, in the year of sale, and it cannot be spread across installment payments even if you're paid over time.

For equipment-heavy businesses — manufacturing, construction, trucking, HVAC — this is often a six-figure item that no purchase-price conversation ever mentions. Plan for that tax bill at closing regardless of how the rest of the deal is structured.

The C-corporation trap

If your business is a C-corporation and the deal is structured as an asset sale, the proceeds are generally taxed at the corporate level first, and again when distributed to you as a shareholder. Two layers on the same money.

This is why C-corp owners and their advisors spend real effort on deal structure, and why the structure conversation belongs at the letter-of-intent stage rather than the closing table. If you're a C-corp and the buyer is insisting on an asset sale, get your CPA involved before you sign anything.

Getting paid over time, and the tax timing problem

Where the price is paid over time — a seller note, an earnout, an installment arrangement — the installment method under IRC §453 generally lets you recognize gain as payments arrive rather than all at closing, reported on Form 6252.

Two limits worth knowing. Depreciation recapture is still due in the year of sale. And where your outstanding installment obligations exceed $5 million, §453A imposes an interest charge on the deferred tax — estimate it with the §453A Interest Charge Calculator.

A structured installment sale uses that same §453 treatment but replaces the buyer's promise with an insurance carrier's: at closing, part of the price is directed to an assignment company that funds your payment schedule through an annuity. Same tax spreading, without your retirement depending on how well the buyer runs the business you just sold.

What this calculator doesn't do

It gives you a directional net-proceeds figure and a simplified tax estimate. It does not model purchase price allocation across asset classes, depreciation recapture, C-corporation double taxation, state-specific rules beyond the flat rate you enter, alternative minimum tax, qualified small business stock exclusions under §1202, or the difference between your personal basis and your entity's inside basis.

Any real transaction needs your CPA's math. Use this to frame the conversation, not to replace it.

Frequently asked questions

How much do I actually keep when I sell my business?

Start with the purchase price, subtract debt paid off at closing, broker or advisory fees, and legal and accounting costs to get net proceeds before tax. Then subtract taxes on the gain. Separately, subtract seller notes, escrow holdbacks, and earnouts to see what actually arrives at closing versus later.

Is an asset sale or a stock sale better for the seller?

Sellers generally prefer stock sales, where the gain is typically long-term capital gain. Buyers generally prefer asset sales, which give them a stepped-up basis in the assets. In an asset sale the price is allocated across asset classes, and items like depreciation recapture on equipment are taxed as ordinary income in the year of sale.

Do I pay tax on a seller note before I'm paid?

Under the installment method, gain is generally recognized as payments arrive rather than at closing. But depreciation recapture is taxed in the year of sale regardless, and electing out of the installment method accelerates everything to year one.

Why are C-corporation asset sales taxed twice?

The corporation recognizes gain on the sale of its assets, and shareholders are taxed again when proceeds are distributed. This is why deal structure matters enormously for C-corp owners and should be settled before the letter of intent.
