How do I calculate the after-tax proceeds from selling my business?

By Michael D. Rubin, CEO & Founder · September 2026 · 913 words

To calculate after-tax proceeds, start with the cash you will actually receive from the sale, subtract your tax basis to find the gain, split that gain into the parts taxed as capital gain and the parts taxed as ordinary income, apply the rates your CPA confirms, and handle money paid in later years separately. The structure of the deal, not only the price, decides most of the answer.

This article explains the concepts so you can follow your CPA's model and ask good questions. It does not give tax rates or tax advice. Your CPA and transaction attorney decide how the rules apply to you.

Step 1: Start with net proceeds, not the headline price

The price in a letter of intent is usually enterprise value: the price for the business before debt and deal terms. From it, company debt is paid off, working capital is adjusted to an agreed target, and part of the price may be held in escrow, paid through a seller note or tied to an earnout. Transaction costs, including advisor, attorney and accounting fees, also come out. What remains is your proceeds before tax, some received at closing and some later.

Your CPA will want this figure broken down by year of receipt, because timing affects the tax. Also list anything you receive that is not purchase price, such as consulting fees for a transition period or rent if you keep the building and lease it to the buyer. Those are income too, but they are taxed differently from the sale itself.

Step 2: Know whether it is an asset sale or a stock sale

In an asset sale, the buyer purchases the company's assets, such as equipment, inventory, customer relationships and goodwill, rather than the company itself. Buyers usually prefer this because they can depreciate what they buy and leave unknown liabilities behind. In a stock sale, or a sale of membership interests in an LLC, the buyer purchases your ownership, and your gain is generally treated as a capital gain on your shares.

Your company's tax status matters. For an S corporation, or an LLC taxed as a partnership, an asset sale's gain generally flows through to the owners. For a C corporation, an asset sale can mean tax at the company level and again when the proceeds are distributed to shareholders, which is why C corporation owners often push for a stock sale. Your CPA confirms which applies to you.

Step 3: Allocate the price

In an asset sale, buyer and seller agree how the price is split among these categories and report the same split. Because each category is taxed differently, the allocation is negotiated, and changing it can move real money between buyer and seller without changing the price at all. A buyer may prefer more of the price assigned to equipment it can depreciate quickly; a seller generally prefers more assigned to goodwill. Settle the allocation with your CPA's input before the purchase agreement is final, not afterward.

Step 4: Account for money paid later

Seller notes, and in many cases earnouts, may allow the gain to be reported as payments are received rather than all in the year of sale, under what is called the installment method. Some items, such as depreciation recapture, are generally taxed in the year of sale even if you have not been paid for them yet. Escrow amounts raise their own timing questions. Your CPA models the tax year by year, so you know how much cash to set aside and when. Remember too that money paid later carries risk: if a note is not repaid or an earnout target is missed, the after-tax figure you planned on will not arrive, which is one more reason to value cash at closing highly.

Step 5: Put it on one page

Run this for every serious offer. Two offers with the same headline can produce very different after-tax results because of structure and allocation, and the article on comparing offers shows what to line up.

• Enterprise value in the letter of intent
• Less debt paid off, the working capital adjustment and transaction costs
• Equals proceeds before tax, split into cash at closing and later payments
• Less your tax basis in the stock or the assets
• Equals total gain, divided by the allocation into capital gain and ordinary income
• Less estimated federal and any state tax on each part, year by year
• Equals after-tax proceeds, now and later

How we work on this with your CPA

MDR & Associates does not give tax advice. We work alongside your CPA and transaction attorney, and we encourage owners to involve them early, while asset-versus-stock and the price allocation are still open. When offers arrive, we set out each one's cash at closing, later payments and structure so your CPA can run the after-tax numbers on real terms. Our ten-step process shows where those decisions fall, and our sell-side service explains the rest. To start with a realistic pre-tax figure, request a free valuation snapshot.
