The price you negotiate is not the money you keep, and the largest single gap between those two numbers is usually taxes. On an MSP-sized deal the tax bill routinely runs 20% to 35% of the gain depending on choices made (or not made) months before closing, which is why the useful version of tax planning starts before the letter of intent, when the structure is still negotiable, rather than in April, when the only remaining question is the size of the check. Here are the basics every seller should hold before the first serious conversation.
The two tax speeds
Nearly everything in a sale gets taxed at one of two speeds. Long-term capital gains rates (federally 15% or 20% for most sellers at exit-sized incomes, plus the 3.8% net investment income tax) apply to gain on capital assets held over a year, and they’re the good speed. Ordinary income rates (up to 37% federally) apply to compensation-flavored dollars, and they’re the expensive speed. The entire game of sale tax planning, reduced to one sentence, is moving dollars from the second bucket toward the first, within what the law and the buyer will allow.
Where your dollars land depends mostly on structure, which you already know from asset sale vs stock sale. A stock sale is the simple case: you sell shares held for decades, essentially the whole gain rides the capital gains rate, one clean layer. An asset sale fragments the price across categories, each with its own treatment, and three fragments deserve special attention.
Depreciation recapture. Every dollar of depreciation you’ve taken on equipment, vehicles, and furniture over the years comes back at sale time: gain on those assets is taxed as ordinary income up to the amount previously depreciated. MSPs are asset-light, so this rarely dominates, but a fleet, a build-out, and years of Section 179 write-offs add up to a five-figure surprise for sellers who’ve never heard the term.
Goodwill. Usually the biggest allocation in an MSP deal, and happily, it’s capital-gain territory. The ratio of goodwill to recaptured-and-ordinary categories in your purchase price allocation is one of the quiet negotiations inside every asset deal, because the buyer’s preferences run the other way. That fight gets its own post later this series.
Consulting and non-compete dollars. Money the deal pays you for future services (transition consulting, employment) is compensation: ordinary rates plus payroll taxes. Payments allocated to a non-compete are ordinary income too. Sellers sometimes ask to shift price into consulting agreements without noticing they’ve volunteered for the worst tax treatment in the deal. Sometimes there are reasons; know you’re paying for them.
One more structural landmine worth naming: the C corporation double tax. A C-corp that sells its assets pays corporate tax on the gain, and the shareholder pays again on the distribution, stacking to a combined rate that can approach half the gain. C-corp owners should treat structure as a first-order deal issue (stock sale, or the elections that mimic one), and as the QSBS post covered, the C-corp facts can also cut the other way for those who planned into them years ahead.
Timing moves the bill too
Two timing levers matter at this scale. Installment treatment: when part of your price arrives over years (a seller note, some earnout structures), you generally recognize gain as payments arrive, which spreads the income across tax years and can keep you out of the top brackets and thresholds. Useful, automatic in many cases, and elective in reverse (you can opt out and pay it all up front, occasionally wise if rates are rising). It also compounds the credit risk you’re already carrying on those dollars, a tradeoff priced elsewhere in this series.
The calendar itself. A December 28 closing versus a January 5 closing puts the entire gain in different tax years, which interacts with everything else in your return: the year you retire, the year the earnout pays, the year you realize losses. Sellers with flexibility on the closing date have a lever most never think to pull.
The state layer
Federal is only half the return. State treatment of a business sale ranges from zero (Alaska, Texas, Florida, and a handful of others tax no personal income) to double digits (California’s top rate reaches into the teens, with no capital-gains discount). For a seller with a seven-figure gain, the state delta can exceed the federal planning wins combined.
Which invites the obvious idea, so here’s the honest version of it: moving to a no-tax state can work, and it has to be a real move, made early. States with money at stake audit exit-year residency changes aggressively, and the test is your life’s actual center (home, time, doctors, community), not a mailbox. Establishing residency after the LOI is signed is generally too late for the sale year, and a sale already in progress at moving time invites a fight you’ll likely lose. If relocation is genuinely in your future anyway, sequence it years ahead of the sale. If it isn’t, don’t let the tax tail wag your life. There’s more state-level nuance (source rules, entity-level taxes) for a later post.
What to do with all this
Three moves, in order. First, know your own facts now: entity type, asset basis and depreciation history, state exposure, and roughly what each structure would net you. That’s one working session with your CPA, and it converts every future negotiation sentence about structure into dollars. Second, bring tax into the deal conversation at the LOI stage, where allocation, structure, and consulting-versus-price decisions are actually made. Third, if your exit is years out, let the big levers (entity, residency, QSBS clocks) into your long-runway planning, because every one of them rewards time and punishes haste.
The tax code doesn’t reward the smartest sellers. It rewards the earliest ones.
