Two owners sell nearly identical companies for the same price. One walks away with millions more. The difference wasn't negotiation. It was the structure.
Here is the short version, TLDR.
The headline price of your sale is not what you keep. How the deal is structured, how your company is organized going in, how the purchase price is allocated, and how the proceeds are timed, determines your after-tax number. And because deal structure gets locked in early, the owners who maximize after-tax sale proceeds are the ones who bring tax planning into the M&A process from day one, not after the papers are signed.
Here's how that works in simple terms, for owners of family-owned and closely held companies.
When owners talk about selling, they talk about the multiple. Eight times earnings. Ten times earnings.
But the multiple is a gross number. Your concern is the net. Between federal capital gains, ordinary income rates, state taxes, and the way the deal is papered, two identical purchase prices can produce after-tax outcomes that differ by seven figures. Tax planning for mergers and acquisitions is not a compliance exercise that happens after the sale. It is a value lever perhaps more critical the price itself.
Every business sale takes one of two basic forms. The buyer purchases your company's assets, or the buyer purchases the company itself.
Buyers almost always prefer to buy assets. It gives them a fresh tax basis they can write off and leaves your history, and your liabilities, behind. Sellers usually prefer to sell the company, because it is cleaner and generally taxed at the lower capital gains rate.
For many closely held companies, an asset sale creates specific problems. If your business is a C corporation, an asset sale can get taxed twice, once inside the company and again when the cash comes out to you. If you have depreciated equipment over the years, part of your gain can get pulled back into ordinary income rates. These are not edge cases. They are the default outcome for owners who let the buyer's preferred structure become the deal by inaction.
The good news is that this fork is negotiable, and the tax cost of each path is calculable in advance. An owner who walks into negotiations knowing exactly what an asset deal costs them versus a stock deal can price that difference into the conversation. An owner who finds out at closing cannot.
You do not have to take the money all at once, and sometimes you shouldn't.
An installment sale spreads your payments, and your tax bill, across multiple years, which can keep you out of the highest brackets. Rolling a portion of your proceeds into equity in the buyer's company defers tax on that portion until the second exit. An earnout ties part of your price to future performance, which carries risk but also shifts income into later years.
Each trades certainty for tax efficiency in a different proportion, and the right mix depends on your family's cash needs, your risk tolerance, and what the rest of your balance sheet looks like. That is a planning conversation, and it needs to happen before the term sheet, because these terms are baked into the term sheet.
Most sales involve a capable team. An investment banker or broker driving price. An attorney papering the deal. A CPA who has done your returns for years.
Here is the gap: the banker is paid on the gross number. The attorney is focused on risk. Your CPA typically sees the deal after it is signed, when the only job left is reporting what happened. Everyone is good at their job, but nobody owns your after-tax number.
That is the case for coordinated M&A advisory services, where transaction guidance and tax strategy sit in the same room from the first conversation. When the people modeling your after-tax outcome are also at the table when structure, allocation, and timing get negotiated, tax planning stops being a post-closing autopsy and becomes part of the deal itself.
Some of the most valuable business sale strategies cannot be executed inside a live deal. Reorganizing how your company is legally structured can take months and may only take effect at the start of a tax year. Positions that reward long holding periods need years, not weeks. And once a buyer signs a letter of intent, the handshake document that kicks off the sale, your structure is effectively frozen.
If a sale is anywhere on your horizon, even three years out, the structural work starts now. We wrote about the timing math in detail here.
The multiple gets the headlines. The structure builds your legacy.
