Asset Sale vs Stock Sale: The Tax Decision That Reshapes Your DFW Business Exit

A Plano manufacturing owner I worked with assumed his $9.4M deal was a $9.4M deal. The LOI said asset sale. He signed. Six months later his CPA showed him the post-tax number: $5.9M after federal tax, state tax in three other states he sold into, and ordinary-income recapture on the depreciated equipment.

The same business sold as a stock sale would have netted him roughly $7.3M.

That $1.4M gap is what the asset sale vs stock sale decision actually costs when DFW owners walk into it cold. Below: how each structure works, why the buyer and the seller want opposite outcomes, the Texas tax math, and the eight LOI terms that decide which structure you live with.

What Is an Asset Sale vs a Stock Sale?

The two structures answer one question differently: what exactly did the buyer just buy?

In an asset sale, the buyer purchases specific assets, equipment, inventory, customer lists, goodwill, contracts, real property, intellectual property. The buyer also assumes only the liabilities both sides expressly agree to. Your legal entity, your EIN, your old tax returns, your historical exposure to lawsuits, environmental issues, and tax audits all stay with you. The buyer typically rolls the assets into a brand-new entity formed for the deal.

In a stock sale, the buyer purchases the equity of the company itself. The corporation or LLC keeps right on operating. Same EIN, same contracts, same employees, same bank accounts, same licenses. The buyer inherits everything, assets, contracts, customer relationships, employees, and every historical liability whether anyone disclosed it or not.

Same business. Two completely different transactions. The IRS, the buyer's lender, the seller's CPA, and the buyer's integration team all care about the difference.

Why Buyers Push Hard for Asset Sales

For sub-$20M deals in DFW: HVAC, plumbing, roofing, electrical, landscaping, manufacturing, dental, distribution, buyers ask for an asset sale almost every time. Three structural reasons drive that preference.

1. Basis step-up creates a 15-year tax shield

When a buyer pays $5M for assets in an asset sale, those assets land on the buyer's balance sheet with a fresh cost basis of $5M. Equipment depreciates over 5 to 7 years. Goodwill and intangibles amortize over 15 years under IRC Section 197. Those write-offs reduce taxable income for the buyer year after year. On a $5M deal with a heavy goodwill component, that step-up can shield $300K to $400K of taxable income annually for 15 years. Real money.

In a pure stock sale, the buyer inherits your old depreciated basis. Equipment that's already been fully written down stays fully written down. Goodwill the seller built over 30 years has zero remaining basis. The buyer loses the depreciation shield entirely.

2. Liability isolation

An asset sale leaves the seller holding the old entity. Any lawsuit, employee complaint, sales-tax audit, or environmental issue that surfaces 18 months after closing belongs to the seller. The buyer simply isn't a party. In a stock sale, the buyer steps into the entity and inherits all of it, including liabilities nobody knew about during diligence.

3. Lender requirements

SBA 7(a) loans, which finance the majority of DFW small-business acquisitions, strongly prefer asset structures. Many SBA lenders won't fund a stock purchase at all without significant additional underwriting. Commercial banks have similar reflexes. If your DFW buyer is using SBA 7(a) financing, plan on an asset sale unless your deal is large enough to pull a non-SBA lender.

Why Sellers Quietly Prefer Stock Sales

The same three factors that make an asset sale attractive to the buyer make a stock sale better for most sellers. The biggest one is taxes.

The C-corp asset-sale trap

If your DFW business is taxed as a C-corporation, an asset sale is a brutal outcome. The corporation pays federal corporate tax on the gain (21 percent). Then, when the proceeds are distributed to you as the shareholder, you pay capital gains tax again (typically 20 percent plus 3.8 percent Net Investment Income Tax). Total effective rate routinely lands between 39 and 45 percent.

The same C-corp sold as a stock sale typically triggers a single layer of long-term capital gains, closer to 23.8 percent all-in for a Texas resident, with no state income tax. On a $5M gain, that's the difference between netting $3.05M and netting $3.81M. Roughly $760K, gone or kept based on structure alone.

The S-corp and LLC angle

For S-corps, LLCs, and sole proprietors, the gap is smaller but still material. An asset sale splits the gain across two tax buckets:

• Goodwill and customer relationships, long-term capital gain. Federal rate of 20 percent for high earners, plus 3.8 percent NIIT.
• Equipment, machinery, and other Section 1245 property, depreciation recapture taxed as ordinary income up to 37 percent at the federal level, plus potential self-employment tax exposure depending on entity.

A pure stock sale of an S-corp typically generates only long-term capital gain on the entire purchase price. Cleaner math, fewer surprises, one tax rate.

Contract continuity

The non-tax issue that sneaks up on DFW owners: contract assignment. In an asset sale, every customer contract, vendor agreement, equipment lease, building lease, software license, surety bond, and government permit has to either be reassigned to the buyer's new entity or rewritten from scratch. Some can't be. A DFW HVAC company with three large commercial maintenance contracts that prohibit assignment without consent can lose those customers between LOI and closing. A stock sale keeps the entity intact, the contracts ride along automatically.

Asset Sale vs Stock Sale: Side-by-Side

The DFW Owner's Real-World Tax Math

The 338(h)(10) Compromise: Best of Both Worlds

When the seller is an S-corp and the buyer is a corporation, there's an elegant federal tax election available: IRC Section 338(h)(10). The legal mechanics are a stock sale, entity stays intact, contracts ride along, no license transfers. The federal tax treatment, by election, mirrors an asset sale. The buyer gets the basis step-up and 15-year depreciation shield. The seller pays the higher (asset-sale) tax bill.

The trick is the price adjustment. Because the seller pays more tax under 338(h)(10) than under a pure stock sale, the seller demands a "tax gross-up", the buyer pays an extra amount roughly equal to the seller's incremental tax burden. The math is real. On a typical $5M to $15M DFW S-corp deal, the gross-up runs 4 to 8 percent of purchase price.

For LLCs taxed as partnerships, a parallel structure called a 336(e) election or an actual asset sale of partnership interests (treated as asset sale under Rev. Rul. 99-6) can achieve a similar outcome. The mechanics are different. The economic result is comparable.

The 8 LOI Terms That Decide Which Structure You Live With

By the time you're three months into a 90-day exclusivity window, leverage is gone. The asset-vs-stock fight has to happen before you sign the LOI. Eight terms every DFW owner should put on the table:

1. Structure named explicitly. The LOI must say "asset sale" or "stock sale" or "stock sale with a 338(h)(10) election." Silence here is a trap: "structure to be determined" almost always becomes whatever the buyer wants by month two.
2. Tax gross-up language if 338(h)(10) is in play. A specific formula or a defined methodology for calculating the seller's incremental tax burden and the corresponding price increase.
3. Allocation of purchase price. Asset sales require an IRS Form 8594 allocation. The LOI should pre-agree the broad buckets, goodwill, equipment, non-compete, working capital, because the allocation drives the seller's tax mix between LTCG and ordinary income.
4. Liability schedule. A list of every liability the buyer will assume in an asset sale, and an explicit statement that everything else stays with the seller entity.
5. Working capital target. Both structures need a working capital adjustment, but the calculation differs. Lock the target methodology in the LOI.
6. Contract-assignment carve-outs. Identify your top 5 to 10 customer contracts and vendor agreements upfront. If any prohibit assignment without consent, decide whether the deal flips to a stock sale or whether the buyer takes assignment risk.
7. Earnout treatment. Whether the deal has an earnout or not, the structure decision affects how earnout payments are taxed under IRC Section 453.
8. Indemnification cap and survival. Stock sales bring inherited liabilities, so indemnity caps and survival periods matter far more than in an asset sale. The standard 10 to 18 percent indemnity cap is non-negotiable in a stock sale.

The DFW Texas Angle

Texas residents have one advantage and one trap when structuring an exit.

The advantage: no state income tax. Texas sellers keep the full federal LTCG benefit without a 5 to 13 percent state tax bite stacked on top. A California or New York seller doing the same deal would lose another 9 to 13 percent of gain. For a Plano, Frisco, or Southlake owner, the after-tax math is meaningfully better, one of the underrated reasons private equity has aggressively expanded its DFW lower middle market book the last three years.

The trap: Texas franchise tax. The Texas Comptroller treats asset sales and stock sales differently, and certain post-closing operating structures can trigger franchise tax surprises on both the seller entity and the buyer entity. Get a Texas M&A tax attorney involved before the LOI is signed, not after the wire arrives.

How Structure Fits the Rest of Your Deal

The asset-vs-stock decision doesn't sit alone. It interlocks with every other piece of the consideration stack:

• Cash at closing is taxed in the year received under either structure, but the character (capital vs ordinary) differs.
• Seller note qualifies for the installment method (IRC Section 453), spreading tax across the payment years.
• Rollover equity can be structured as a tax-deferred rollover if the buyer is using a structure that allows it, usually impossible in a pure asset sale.
• Earnouts are taxed under the installment method when treated as additional purchase price, achievable in both structures with the right language.
• Working capital true-up is treated as a purchase price adjustment under both structures, but the entity-level impact differs.

A clean deal stack starts with the right structure. The wrong structure makes every other piece more expensive.

The Truth Most Sellers Don't Hear Until It's Too Late

Buyers and their lawyers run hundreds of these. They know exactly which structure costs them less, which one transfers liability cleanly, which one their lender requires. Most DFW owners exit once. The asymmetry is enormous.

At Kingdom Broker, the asset-vs-stock conversation is one of the first we have with a seller, alongside owner dependency, customer concentration, the working capital adjustment, and the earnout structure. Three of those decide what the headline price will be. Two decide how much of it actually reaches your bank account. The asset-vs-stock choice is the one that quietly moves the most money on closing day, in either direction.

Your business has a story. The IRS shouldn't get to write the ending.
