Introduction

Two owners sell similar companies in the same year. Each signs for $10 million, and each goes home and tells their family the number.


The sale price may be the same, but what the seller puts in their pocket is not. One owner sold stock while the other sold assets, accepted the buyer's schedule for dividing the price, and signed a noncompete that carried $1 million of the purchase price. Under the assumptions in Section 4, the second owner pays about $340,000 more in federal tax on the same headline price. Neither one negotiated badly on price. The difference here is in the negotiated terms of the deal.


Most owners spend twenty years building value and a few weeks deciding how to get paid for it. By the time a letter of intent (LOI) arrives, the conversation is about the multiple. The terms that decide the after-tax result (the structure of the sale, how the price is divided among assets, when the money arrives, and what you agree to do afterward) often get settled in a page or two of the LOI and then handed to the lawyers.


Our earlier paper on exiting your business while preserving your legacy covered who you might sell to. This paper covers what comes after you choose a buyer: the deal terms that move real money, how each one is taxed, and the questions to answer before you sign anything.

1. Why This Matters

The headline price is a pre-tax number. Every term in a purchase agreement moves one of three dials:

  • Character. Is a dollar taxed as long-term capital gain, with a top federal rate of 20%, or as ordinary income, with a top rate of 37%? (1)

  • Timing. Do you receive the dollar, and pay tax on it, at closing or over several years?

  • Certainty. Is the dollar guaranteed at closing, or does it depend on the business hitting targets after you no longer run it?


A buyer who agrees to your price can win back a lot on these three dials. Buyers and their advisors tend to do many deals, while most sellers only do one in their lifetime.

2. Asset Sale or Stock Sale

The first structural question is what are you actually selling?


Stock Sale

In a stock sale, you sell your ownership in the company. For a corporation, your gain is generally long-term capital gain on the difference between the price and your basis in the shares. The buyer takes the company as it is, including its history, and keeps the company's existing tax basis in its assets.


Asset Sale

In an asset sale, the company sells its equipment, inventory, customer relationships, and goodwill. Each asset is taxed according to its own character, so part of your gain can be ordinary income. The buyer receives a new tax basis equal to what it paid and can depreciate or amortize it. Goodwill and a seller's noncompete are amortized over 15 years (2). Buyers generally prefer asset purchases for that basis. Sellers generally prefer stock sales (3).


The Middle Ground for S-Corporations

A Section 338(h)(10) election or an F reorganization can let a deal be a stock sale for legal purposes while the buyer receives asset-sale tax treatment (3). These structures are common, but they are not free to the seller. A 338(h)(10) election requires both parties to agree, and it can fail if the company’s S-corp election was terminated and the problem was never cured. Inadvertent terminations can often be fixed through IRS relief, but that takes time, so find out before a buyer does. (3). A defect in an S-Corp election from years ago can surface in due diligence and change the deal. Have your CPA and attorney review your S-Corp election history before you go to market.


C-Corporations

For a C-corporation, structure carries even more weight. An asset sale out of a C-corporation generally produces two layers of tax: one at the corporate level and another when the proceeds are distributed to shareholders (4). That is why C-corporation owners push hard for stock sales, and why a stock sale may also be the path to the QSBS exclusion for qualifying shares.


LLCs Taxed as Partnerships

Selling a partnership interest is treated as the sale of a single capital asset, but the gain tied to unrealized receivables, inventory, and depreciation recapture is still ordinary income and cannot be reported on the installment method (5). The stock-sale advantage shown in Section 4 is mainly a corporate one. If you are unsure how your entity will be taxed on a sale, our paper on choosing the right business entity is a good starting point for that conversation with your CPA.

3. Purchase Price Allocation: The Second Negotiation

In an asset sale, agreeing on the price is the first negotiation. Agreeing on how to divide it is the second.


Federal rules require buyers and sellers to allocate the price across seven asset classes using the residual method. Value fills each class in order, up to fair market value, and whatever remains becomes goodwill (6). Both parties report the allocation on Form 8594 (6). If you agree to an allocation in writing, it binds both of you unless the IRS determines the amounts are not appropriate (5).


Class

What It Includes

Typical Tax Character to the Seller

I

Cash and bank deposits

No gain

II

CDs, government securities, publicly traded stock

Usually little or no gain

III

Accounts receivable and other debt instruments

Ordinary income if not already taxed (common for cash-basis businesses)

IV

Inventory

Ordinary income (5)

V

Equipment, vehicles, furniture, buildings, land

Ordinary income up to prior depreciation on equipment (5); up to 25% on real estate depreciation (1); remainder generally capital gain

VI

Section 197 intangibles: customer lists, licenses, noncompete

Varies by asset; a noncompete is ordinary income (7)

VII

Goodwill and going concern value

Generally long-term capital gain

Asset classes per the Form 8594 instructions (6). The tax character column is a general summary; your CPA should confirm the treatment of each asset in your deal.


Why the Buyer Cares More Than You Think

Every dollar the buyer moves from goodwill into equipment shifts its deduction from a 15-year schedule (2) to a much faster one. Under the One Big Beautiful Bill Act, 100% bonus depreciation is permanent for qualifying property placed in service after January 19, 2025 (8). A buyer may be able to deduct every dollar allocated to qualifying equipment in the first year, while goodwill takes fifteen. That gap gives buyers a strong reason to push value into equipment, where your gain is ordinary income to the extent of prior depreciation (5).


The schedule also must be defensible. The amount allocated to any asset other than goodwill cannot exceed its fair market value (6). An independent equipment appraisal is your best protection against an aggressive buyer schedule.

4. Example: Same Price, Three Outcomes

The following is a hypothetical illustration, not a projection for any client.


Assumptions

  • An S-corporation with one owner who materially participates in the business, located in Texas (no state personal income tax).

  • Sale price of $10,000,000, cash-free and debt-free. The owner's stock basis is $1,000,000, equal to the company's basis in its assets.

  • Inventory worth $800,000 with an $800,000 basis. Equipment originally purchase for $2,000,000, now worth $1,200,000 with a $200,000 adjusted basis after $1,800,000 of prior depreciation. The remaining $8,000,000 is goodwill with a zero basis.

  • All gain is taxed at top federal rates: 20% for long-term capital gain and 37% for ordinary income (1). No net investment income tax applies because the owner materially participates (see Section 6).


The Three Offers

Offer A (stock sale). The owner sells the shares. The entire $9,000,000 gain is long-term capital gain. Federal tax: $1,800,000.


Offer B (asset sale at fair market value). The $1,000,000 gain on equipment is depreciation recapture taxed as ordinary income (5): $370,000. The $8,000,000 goodwill gain at 20%: $1,600,000. Federal tax: $1,970,000.


Offer C (asset sale with a $1,000,000 personal noncompete). The buyer moves $1,000,000 out of goodwill and pays it to the owner for a noncompete. Equipment recapture: $370,000. Goodwill of $7,000,000 at 20%: $1,400,000. Noncompete of $1,000,000 at 37%: $370,000. Federal tax: $2,140,000.


 

Offer A: Stock Sale

Offer B: Asset Sale

Offer C: Asset Sale + Noncompete

Headline price

$10,000,000

$10,000,000

$10,000,000

Long-term capital gain

$9,000,000

$8,000,000

$7,000,000

Ordinary income

$1,000,000

$2,140,000

After-tax proceeds

$8,200,000

$8,030,000

$7,860,000

Difference vs. Offer A

None

($170,000)

($340,000)

If the owner doesn’t materially participate, the 3.8% net investment income tax generally applies as well, raising Offer A’s federal tax to $2,142,000. See Section 6.


What This Really Means

The $340,000 gap equals 3.4% of the price. Few owners would accept a 3.4% price cut without a fight, yet many accept the same economics through structure without realizing it because it sits in a schedule.


The other side of the table matters, too. In Offers B and C, the buyer receives a stepped-up basis to depreciate and amortize, which it does not receive in Offer A. That tax benefit is worth money to the buyer. Our view: if a buyer insists on asset treatment, it is reasonable to ask for a price that shares some of that value. Whether you can get it depends on how many buyers want your business.


This example ignores state taxes, transaction costs, payroll or self-employment taxes on any employment or consulting pay, and the lower brackets that apply to part of any gain. Your numbers will differ, which is the point of modeling them before the LOI.

5. When the Money Arrives

The full purchase price is often not wired at closing. The terms that delay payment carry their own tax rules and their own risks.


Seller Financing

If you accept a note for part of the price, the installment method generally lets you report gain as principal is paid rather than all at once (5). Three limits matter.

  • Depreciation recapture is taxed in the year of sale whether or not you received the cash (5). In Offer B, that is $1,000,000 of ordinary income taxed in the year of closing even if $2,000,000 of the price sits in a note.

  • Gain on inventory cannot be deferred, and interest on the note is ordinary income (5).

  • When the sale price exceeds $150,000 and the face amount of installment obligations arising in the year and outstanding at year-end exceeds $5,000,000, Section 453A charges interest on the deferred tax (9). Large seller notes lose much of their deferral value.


The bigger issue is not tax. A seller note makes you a lender to the person who bought your company, often behind the buyer's bank. Before you agree to one, ask your attorney what security you hold and what happens if the business struggles under new ownership.


Earnouts

An earnout pays part of the price only if the business hits targets after closing. Because the total price can’t be known at the end of the year of sale, special contingent payment rules govern how the gain is reported (5). The tax rules are manageable. The business risk is the problem: the buyer now controls the budget, the accounting, and the decisions that determine whether you get paid. An earnout tied to your continued employment can also invite the argument that the payments are compensation rather than purchase price, which would turn capital gain into ordinary income. Have your attorney and CPA review the drafting and treat earnout dollars as uncertain until they arrive.


Escrows and Holdbacks

Buyers commonly hold back part of the price to cover claims that surface after closing. The tax treatment depends on the arrangement. An irrevocable escrow that simply funds your remaining payments is treated as payment in full, so the installment method does not apply. An escrow that places a real restriction on your right to the money can still qualify (5).


Rollover Equity

Private equity buyers often ask sellers to reinvest part of the proceeds in the buyer's company. A properly structured rollover can defer tax on the rolled portion under Section 721 for partnerships or Section 351 for corporations. Which rule applies depends on how the buyer’s holding company is taxed, not on how your company is organized and some deals use a tax-free reorganization instead. Deferred is not forgiven. You pay when the buyer eventually sells. The buyer also receives no stepped-up basis on the rolled portion, which can affect price. (10)


The rolled equity is usually a minority, illiquid stake whose exit date is set by someone else. If one reason for selling was to reduce the concentration of your net worth in a single company, a large rollover keeps part of that concentration in place. That can be the right trade if you believe in the buyer's plan but be sure to make that decision on purpose.

6. The 3.8% You May Not Owe

The net investment income tax adds 3.8% to investment income, including gain from selling property, once income exceeds certain thresholds. Gain on property held in a trade or business in which you materially participate is generally excluded, and Section 1411(c)(4) applies similar logic to the sale of an interest in an S-corporation or partnership (11). The exclusion covers gain tied to the operating business. Gain attributable to excess cash or investments held inside the company can still be subject to 3.8%


The second-order point: an owner who steps back from daily operations years before a sale may no longer meet the material participation tests. On a $9,000,000 gain, 3.8% is $342,000. The material participation rules include tests that look back over prior years, so the answer depends on your history. Confirm your status with your CPA before you change your role, not after an LOI arrives.

7. Personal Goodwill

In some businesses, customers follow the owner rather than the company. Courts have recognized that goodwill tied to an owner's personal relationships can belong to the owner rather than the corporation. In Martin Ice Cream v. Commissioner (1998), the Tax Court held that such relationships were not corporate assets where the owner had no employment contract or noncompete with the company (12). When an owner sells personal goodwill directly, that portion of a C-corporation asset sale can avoid the corporate-level tax (4).


The strategy fails when the facts do not support it. In Howard v. United States, a dentist had signed an employment agreement and noncompete with his own corporation years earlier. The court held the goodwill belonged to the corporation, and the IRS recharacterized his capital gain as a dividend (13). If you operate as a C-corporation, personal goodwill deserves a look with your attorney and a qualified appraiser well before a sale. It cannot be created at the closing table.

8. Planning Considerations

Before you sign an LOI, you should be able to answer these questions:

  • What do I need after tax to fund the life I want after the sale? Start here, not with the multiple.

  • Is my entity in good standing, and is my S-Corp election (if any) clean?

  • If the buyer wants an asset deal, what is my after-tax number under its proposed allocation, and what price would make me whole?

  • How much of the price am I willing to receive later, and how much am I willing to risk on someone else's management?

  • Will I materially participate right up to the sale? If not, what does the 3.8% cost?

  • Do I want ongoing exposure to the business through rollover equity, or a clean break?

  • What gifts to family or charity should happen before a sale is locked in? Once a binding agreement exists, a transfer of business interests may not shift the gain away from you. Your attorney should set this timeline.

9. Implementation Steps

24 to 12 Months Before a Sale

  • Bring your financial records to the standard a buyer's diligence team will expect. Ask your CPA whether a quality of earnings review makes sense.

  • Have your CPA confirm your entity status, S-corp election history, asset basis, and depreciation schedules.

  • Review any employment agreement or noncompete between you and your own company if personal goodwill may apply.

  • Model after-tax proceeds under both stock and asset structures.

  • Complete any pre-sale gifting or charitable transfers on the timeline your attorney recommends.

When Offers Arrive

  • Compare offers on after-tax, risk-adjusted value, not headline price.

  • Settle structure and allocation principles in the LOI rather than leaving them for the purchase agreement.

  • Define earnout metrics, accounting methods, and your information rights in writing.

  • Decide what security and priority any seller note will have.

At Closing

  • Confirm the final allocation schedule and that both parties will report the same numbers on Form 8594 (6).

  • Plan estimated tax payments for year-of-sale income, including recapture on deferred deals (5).

After Closing

  • Track note payments, earnout results, and escrow releases along with their tax reporting.

  • Put the proceeds under a written plan before they sit in a checking account.

9. Risks and Pitfalls

  • Negotiating price and ignoring terms. The multiple gets the attention, but the structure decides taxation and ultimately what you walk away with.

  • Accepting the buyer's allocation schedule without review. It is drafted to benefit the buyer. An independent appraisal of tangible assets gives you a basis to push back.

  • Spending earnout dollars before they arrive. Plan your life around the guaranteed portion of the price.

  • Assuming an installment sale defers everything. Recapture and inventory gain are taxed in the year of sale (5), and large notes can trigger an interest charge (9).

  • Discovering an S-corp election problem in diligence. An uncured problem can undo 338(h)(10) treatment (3) and cost you price or time.

  • Stepping back too early. Losing material participation can add 3.8% to your gain (11).

  • Planning after the paperwork. Gifts made after a binding agreement and personal goodwill claimed without supporting facts tend to fail.

  • Overlooking state taxes. Texas has no personal income tax, but a business with operations in other states may face tax in those states depending on the structure. Ask your CPA.

Conclusion

You may only get one exit while the buyer's team has done many. The price gets the headlines, but the terms decide how much of it reaches you.


Most of your negotiating power exists before the LOI is signed. After that, the shape of the deal is set, and the remaining work is drafting. Owners who model the after-tax result of each structure, clean up their entity and records early, and treat deferred dollars as uncertain walk away with more of what they built.


If a sale could happen in the next three years, now is the time to run the numbers.
