Tax strategists don’t have crystal balls. We don’t know where our clients are going.
A better metaphor for strategy is a map. A good advisor can show the paths available, the traps in the terrain, and help estimate where the treasure may lay.
In Part 1 of this series, we mapped the fork between S-corporation and C-corporation status. In Part 2, we covered one of the more sobering realities for a large share of our readers: many service businesses, accounting, law, consulting, health, financial services, most rental and brokerage real estate, hotels, and restaurants are excluded from the federal capital-gains-free exit available under §1202.
Without that shelter, most small businesses in these industries lean on S-corporation treatment instead. And why wouldn’t they? Between the QBI deduction and a real reduction in self-employment taxes, the S-corp remains a powerful stand-alone tax strategy on its own.
The data backs this up. S-corps tend to be profitable, small businesses and they’re used exactly by the demographics you’d expect.
- Profitable. Taxpayers with an adjusted gross income of $200,000 or more earned approximately 95 percent of all S-corporation income in 2021, according to the American Action Forum.
- Small — but not that small. The Bureau of Economic Analysis found that 89.9 percent of all S-corps have fewer than 20 employees, and 70 percent of that group has fewer than five. Don’t let the “S” fool you, though across the full distribution of S-corps, about half of all S-corporation net income sits above $1 million per year.
We can’t ignore the power of the S-corp. Nor can we ignore the planning that has to happen around it, especially at the exit.
S-corp owners have a different tool set than their C-corp counterparts. It’s not as clean as a 100 percent federal exemption. But it’s structurally rich, well-documented, and used by every private equity firm and strategic acquirer that comes to the table. And just like the C-corp playbook, the work that actually drives the outcome typically has to start 18 to 24 months before the deal closes.
The window between LOI and closing carries the same threats an S-corp faces as a C-corp: buyer dynamics, federal tax, state tax, and your own tax history and exposure. The tools to navigate them, however, are different.
If X marks the spot where the exit happens, here’s the map for how S-corps get home without losing too much plunder.
Buyer vs. Seller: The Battle Isn’t Over Yet
If the purchase price and terms didn’t strain the relationship enough, wait until deal structure hits the table.
Buyers want asset sales. Sellers want stock sales. Both sides have good reasons.
Why Buyers Want an Asset Sale
Buyers get a stepped-up basis in the assets they acquire, which minimizes their future tax bill. They can then depreciate and amortize the purchase price against future income. By some estimates, that structure is worth eight to 15 percent of the purchase price in present-value tax savings to the buyer.
Why Sellers Want a Stock Sale
Sellers, understandably, want the opposite. A stock sale creates a single layer of gain, no corporate-level tax, taxed at capital gains rates (roughly 23.8 percent federal). The company’s history goes with the buyer, and the transaction feels far more straightforward.
The Best of Both Worlds
Fortunately, for an S-corp, the federal tax code offers three structures that fuse the two positions: the seller sells stock for legal purposes, while the deal is treated as an asset sale for tax purposes.
The buyer gets the step-up. The seller stays single-layer. It’s the have-your-cake-and-eat-it-too approach and we’ll walk through exactly how it works below.
The Trap You Can’t Step On: Protecting Your S-Election
Before we get to those fusion structures, there’s a trap that costs founders more than any individual deal mechanic.
An S-corp may only be owned by U.S. individuals, certain trusts (QSSTs and ESBTs), and estates. Corporations and partnerships are not eligible S-corp shareholders.
If you sell S-corp stock directly to a corporate or partnership “holding company” without using one of the structures below, the S election terminates automatically the day of the sale, under §1362(d)(2). The buyer inherits a freshly minted C-corp, with all the double-tax consequences that come with it.
This is the exact failure the structures below exist to prevent. Pick one before you sign the LOI. There’s no good fix once you’ve already closed.
Structuring the Sale: Five Paths Forward
A clean stock sale is the baseline: one tax, mostly capital, the cleanest closing possible. Every path below is a variation on what happens when the buyer won’t accept that baseline or when the deal calls for something different.
Path 1 — The Baseline: Clean Stock Sale
Sell the shares. Report the gain on Schedule D. Federal tax runs around 23.8 percent (long-term capital gains plus the Net Investment Income Tax). No election forms, no recapture, no headache.
The tradeoff: the buyer inherits the corporation’s existing tax basis, with no step-up to the purchase price. Many strategic buyers will accept that to get the deal done. Most private equity firms won’t.
Founder beware: if your buyer is a strategic acquirer willing to skip the step-up, none of the four alternatives below apply to you. This is your path.
Path 2 — The Joint Election: §338(h)(10)
Sell the stock legally. Treat it as an asset sale for tax purposes. The buyer must be a corporation, and both sides jointly file Form 8023 within nine months of closing.
This election exists specifically to resolve the buyer-seller conflict we described above buyers get the stepped-up basis they want for future depreciation, while sellers keep the simplicity and favorable capital gains treatment of a stock sale.
The catch: the seller picks up ordinary income on recapture and inventory. That extra tax is typically offset by a “gross-up” of three to eight percent added to the purchase price, which the buyer usually pays because the step-up is worth more to them than the gross-up costs as long as you remember to negotiate for it.
Bottom line: if your buyer is a corporation and wants the step-up, start here.
Path 3 — The Solo Election: §336(e)
Same tax effect as §338(h)(10), but elected unilaterally on the seller’s side.
This one matters when the buyer isn’t a corporation. Most private equity funds are structured as partnerships, which takes §338(h)(10) off the table. §336(e) fills that gap, same math, without needing a buyer signature.
Path 4 — The PE Standard: F-Reorg + LLC Sale
Roll the S-corp under a new HoldCo. QSub-elect the legacy corporation. Convert it to an LLC. Sell the LLC interests.
For tax purposes, the buyer is acquiring assets. For legal purposes, the seller is selling LLC units. Rollover equity flows tax-deferred into the buyer’s TopCo under §721.
Bottom line: when private equity wants 20 to 30 percent rollover equity (or whatever percentage they’re willing to allow), this is the structure that accommodates it. §338(h)(10) can’t handle rollover cleanly.
Path 5 — The Underrated, No-Tax Back Door: §1042 ESOP
For owners who want out of day-to-day operations but don’t want a strategic buyer or a private equity firm running what they built, selling to an Employee Stock Ownership Plan is worth serious consideration.
Done correctly, the seller can defer 100 percent of federal capital gain by reinvesting proceeds into “qualified replacement property” under §1042.
This path is most common among mature, profitable, owner-operator companies in the $20 million to $250 million range. Valuation and execution are expensive, and the strategy requires a next-generation leadership team ready to run the business post-exit.
It’s not for everyone. But it’s worth knowing it exists, the accounting firm BDO’s recent transition is a well-known example of this structure in action.
The Math: A $50 Million Case Study
Same business. Same buyer. Same price. Different structure, different result.
The setup: A 16-year-old S-corp manufacturing business sells for $50 million. The owner’s basis is $4 million, built through years of reinvested K-1 income. On a deemed asset sale, the gain breaks out as $36 million of goodwill and §1231 capital assets, plus $10 million of §1245 recapture and inventory (taxed as ordinary income). The company is based in Texas, no state tax to layer in.
- Clean stock sale. The seller’s purest path. No recapture, no election required. The owner walks away with $39 million.
- §338(h)(10) with gross-up. The seller picks up $1.32 million more in federal tax than the clean sale, but the buyer covers it with $3 million of additional purchase price. Net result: the seller ends up $966,000 better off than the clean stock sale, and the buyer still keeps about two-thirds of the step-up’s value.
- F-Reorg with rollover. Less cash at closing, but $10 million of rolled equity carries $9.2 million of deferred gain. If private equity sells the business again in five years at 2x value, the seller recognizes $19.2 million at 23.8 percent, or roughly $4.57 million of additional tax. The net “second bite” comes to about $15.4 million after tax. Combined across both exits, total proceeds land around $45.6 million.
Bottom line: on the exact same $50 million business, the seller’s after-tax outcome ranges from $39 million on a clean stock sale, to roughly $40 million with a §338 gross-up, to $45 million or more with a successful F-Reorg rollover. The structure matters more than the negotiation.
Five Traps That Turn a Good Deal Bad
Every path above carries a trap that can quietly erode the outcome. Five matter most.
- §1374 BIG tax. If your S-corp was previously a C-corp, a five-year clock applies. A deemed asset sale inside that window triggers a 21 percent corporate-level tax on the appreciation that existed at conversion on a mid-market deal, that can mean $2–4 million of extra tax. The clock can’t be accelerated. Model it early, and if you’re still inside the window, consider waiting.
- §453B(h) installment timing. If a seller note is part of the price, adopting a plan of liquidation before the asset sale closes and completing liquidating distributions within 12 months, lets the corporation pass installment notes to shareholders without triggering immediate corporate-level gain. Miss the timing, and the deferral dies at the corporate level. It’s one of the most powerful, and most often missed, S-corp planning moves available.
- S-election validity. Diligence almost always turns up something: an ineligible shareholder who briefly held shares, a missed QSub election, a single-class-of-stock issue. Rev. Proc. 2013-30, Rev. Proc. 2022-19, and §1362(f) relief cover most of these defects, but the cures take weeks. Build that time into your LOI calendar.
- Suspended losses. Basis-limited losses die on a stock sale unless basis is restored beforehand. A late capital contribution can release seven figures of suspended loss against the sale gain — but only if diligence happens before the wire goes out.
- Multi-state tax. A deemed asset sale sources gain across your entire operating footprint. Multi-state businesses can trigger five to 15 state tax returns and two to six percent in incremental state tax. Model this at LOI, not after signing.
Which Path Is Yours?
Three archetypes cover most of what we see in practice.
- Selling to a strategic corporate buyer? §338(h)(10) is typically the path of least resistance. Negotiate the gross-up explicitly in the LOI, and clear any historical S-election defects before you close.
- Selling to private equity? F-Reorg plus LLC sale plus rollover has become the modern default. Model BIG tax exposure if your S-election is under five years old, and lock in your §453B(h) plan before closing if a seller note is involved.
- Not ready to hand the company to a stranger? The §1042 ESOP path deserves a hard look, a tax-deferred exit where your employees become owners and you stay involved at whatever level makes sense for you.
The common thread across all three: most mid-market founders don’t have a tax advisor at the LOI table. By the time their accountant gets the call, the structure is mostly written, the gross-up is unnegotiated, and the §453B(h) plan never got drafted.
That’s the difference a Fortune 500-caliber tax team makes. A large corporate deal has tax counsel in the room before the term sheet is finalized. The same approach scales down to founder-led businesses, it just has to be set up by someone before the founder needs it.
“X” Marks the Spot
The difference between a default exit and a planned one is rarely five to 10 percent.
It’s often 25 to 50 percent of the after-tax outcome.
That’s the difference between “we did fine” and “we built generational wealth.”
