Seller Financing a Business Sale: Taxes, Allocation and the Note
Seller financing a business lets you report part of the gain as the note is paid, but only part. Under the installment method (IRC §453), gain on goodwill, real estate and other eligible assets is taxed as principal arrives. Inventory gain and depreciation recapture on equipment are taxed in the year of sale, even if most of the price comes later. So the tax result of a seller-financed business sale is decided less by the size of the note and more by how the price is split among the assets.
This page walks through how seller notes work in business sales, why the purchase price allocation matters, what cannot be deferred, and a worked $3 million example with the tax by year. To run your own numbers, use the calculator.
How seller notes work in business sales
In a seller-financed business sale, the buyer pays part of the price at closing (often from a bank loan plus the buyer's own cash) and gives you a promissory note for the rest. You receive principal and interest over the note's term.
The share of the price a seller carries varies widely by deal, industry and buyer. There is no tax rule that sets it. If the buyer is using a bank or SBA-backed loan for the cash portion, that lender will have its own rules about seller notes, which can limit when and how you are paid. Get the lender's terms in writing before you agree to a note.
For tax purposes, three things decide how much gain you can defer:
- Asset sale or stock sale. They are taxed differently.
- The purchase price allocation. In an asset sale, the price is divided among the assets, and each asset follows its own rule.
- Year-of-sale items. Inventory and recapture are taxed now, whatever the note says.
Asset sale vs stock sale
Asset sale. The business sells its assets (equipment, inventory, goodwill, maybe real estate). Each asset is treated as sold separately, and each one has its own gain and its own character. This is where allocation matters.
Stock or interest sale. You sell your shares or your LLC or partnership interest. Stock of a private company can generally use the installment method. Publicly traded stock cannot (§453(k)(2)). A partnership interest is only partly eligible: your share of depreciation recapture and other "hot asset" income is ordinary and taxed in the year of sale (§§751(a), 453(i)(2)), and your share of partnership debt counts as part of the price (§752(d)). IRS Pub. 537 states that gain allocated to unrealized receivables and inventory in a partnership interest sale can't be reported on the installment method. We cover that in detail in installment sales of stock and partnership interests.
Purchase price allocation (Form 8594) and why it decides what can be deferred
In an asset sale of a going business, buyer and seller must allocate the price among the assets using the residual method (§1060). Under IRS Pub. 537, the price is applied in class order: cash and deposit accounts first, then securities and similar items, then receivables and other debt instruments, then inventory, then all other assets (equipment, real estate), then other §197 intangibles, and last goodwill and going concern value.
Two rules make this a negotiation, not a formality:
- A written allocation is binding on both sides. Under §1060(a), a written agreement on the allocation or on asset values "shall be binding on both the transferee and transferor," unless the IRS finds it inappropriate.
- Both sides report it. The buyer and seller each attach Form 8594 to their returns for the year of sale.
The buyer generally wants more price on fast-depreciating assets like equipment. You generally want more on goodwill and real estate, which can ride the note and are usually capital or §1231 gain. Every dollar the buyer moves into equipment can become ordinary recapture that you pay tax on in year one (see Section 1245 recapture). For how every asset in the deal is taxed, including asset vs stock sales and C corporations, see selling a business: tax implications.
What cannot use the installment method
| Asset or item | Installment method? | Why |
|---|---|---|
| Inventory | No | §453(b)(2)(B); ordinary income in year of sale |
| Equipment gain up to prior depreciation | No | §1245 recapture is recognized in year of sale (§453(i)) |
| Publicly traded stock or securities | No | §453(k)(2) |
| Dealer property | No | §453(b)(2)(A), (l) |
| Goodwill, going concern value | Yes | Eligible, usually capital gain |
| Real estate (building and land) | Yes, except ordinary recapture | Unrecaptured §1250 gain is deferred with the payments (Reg. §1.453-12) |
| Equipment gain above prior depreciation | Yes | Only the excess over recapture |
Accounts receivable are not on the IRS list of assets that cannot use the installment method in a direct asset sale (Pub. 537 lists inventory, dealer property, and stocks and securities). The receivables limit in Pub. 537 applies to the sale of a partnership interest. Your CPA should still look at how receivables of a cash-method business are treated in your deal.
Payments for your own future work, such as a consulting agreement or a noncompete, are ordinary income to you, not sale price for your assets. Keep them separate in the documents.
Worked example: $3M asset sale, 25% seller note
Simple example. Round numbers, one owner who materially participated in the business, married filing jointly, $100,000 of other ordinary income each year, standard deduction, 2026 federal brackets held flat (Rev. Proc. 2025-32). Federal income tax only. Note interest is left out; it is ordinary income every year on top of this. No selling expenses.
A company sells its assets for $3,000,000. The buyer pays $2,250,000 at closing and gives the owner a $750,000 note, paid in five equal annual principal payments of $150,000 starting the year after the sale.
Step 1: allocate the price.
| Asset | Price allocated | Adjusted basis | Gain | Character and timing |
|---|---|---|---|---|
| Inventory | $300,000 | $200,000 | $100,000 | Ordinary, year of sale |
| Equipment (cost $900,000, $700,000 depreciation taken) | $400,000 | $200,000 | $200,000 | All §1245 recapture, year of sale |
| Goodwill (self-created) | $2,300,000 | $0 | $2,300,000 | Capital gain, eligible for installment method |
| Total | $3,000,000 | $400,000 | $2,600,000 |
The equipment's gain ($200,000) is less than the depreciation taken ($700,000), so all of it is recapture. Following the method in Pub. 537's sale-of-a-business example, the inventory and the equipment come out of the installment computation because all of their gain is reported in the year of sale.
Step 2: find the installment share of each payment. Only goodwill is left in the installment sale: $2,300,000 of $3,000,000, or 76.67% of every principal dollar. Its gross profit percentage is 100% (no basis).
Step 3: gain by year.
| Year | Principal received | Installment share (76.67%) | Goodwill gain | Year-of-sale items | Total gain |
|---|---|---|---|---|---|
| Year of sale | $2,250,000 | $1,725,000 | $1,725,000 | $300,000 | $2,025,000 |
| Years 2 to 6, each | $150,000 | $115,000 | $115,000 | $0 | $115,000 |
| Total | $3,000,000 | $2,300,000 | $2,300,000 | $300,000 | $2,600,000 |
The surprise: a 25% note defers only $575,000 of the $2,600,000 gain. Year one still carries 78% of it, because the cash at closing is large and the ordinary items cannot move.
Step 4: federal income tax attributable to the sale (simple example).
| Year of sale | Years 2 to 6, each | Total | |
|---|---|---|---|
| Seller financing as above | $398,533 | $12,585 | $461,458 |
| All cash at closing | $513,533 | $0 | $513,533 |
The note lowered total federal income tax on the sale by about $52,000 in this simple example, because the $575,000 of goodwill gain in the later years left the 20% bracket: about $31,100 a year landed in the 0% band and the rest in the 15% band. That is real money. It is also a smaller effect than many owners expect from "carrying 25%."
Because this owner materially participated, the gain is nonpassive trade or business gain and is outside the 3.8% net investment income tax (§1411(c)(1)(A)(iii)). A silent owner's gain generally is subject to it, and the note interest is net investment income either way. State tax is not shown.
Protecting the note
A business note is usually riskier than a real estate note. The collateral (equipment, receivables, customer relationships) can lose value quickly if the new owner struggles. Common protections, all worth discussing with your attorney:
- A security interest in the business assets, perfected by a UCC filing.
- A personal guaranty from the buyer and, where appropriate, the buyer's spouse.
- Financial reporting covenants, so you see trouble early.
- Default and cross-default terms, including what happens if the buyer defaults on the bank loan.
- Life insurance on the buyer, payable toward the note.
- A clear position relative to the bank. If the bank requires your note to be subordinated, you are behind the bank if things go wrong.
Earn-out vs note. An earn-out ties part of the price to future results. For tax, it is a contingent payment sale (Temp. Reg. §15a.453-1(c)). Set a maximum price or a fixed term: with neither, basis is recovered over 15 years and the arrangement is closely scrutinized. A fixed note is simpler to report and to enforce.
Selling or pledging the note later. Selling or giving away the note triggers the deferred gain (§453B), and on sales over $150,000, borrowing against the note is treated as receiving payment (§453A(d)). If the notes from the year's sales exceed $5 million at year end, an interest charge applies to the deferred tax on the excess (§453A). See the §453A interest charge and pledge rule.
Structured installment sale as an alternative for the cash portion
Some owners do not want to be the buyer's lender at all, but still want the eligible gain spread over years. A structured installment sale is one option: the buyer pays in full at closing, and the obligation to pay you over time is assigned to an assignment company, usually funded by a fixed annuity the assignment company owns (some programs use a funding agreement instead).
Weigh it objectively:
- You are an unsecured creditor of the assignment company, not of the buyer.
- No statute, regulation or published IRS ruling specifically approves the assignment structure. It relies on the general §453 rules, and your own tax counsel should review the documents.
- The payments are locked: no early cash-out, no borrowing against them.
- The producer's commission is built into the pricing rather than billed separately.
It does not change the year-of-sale rules. Inventory and recapture are still taxed in year one. See structured installment sales and seller financing taxes for how the two compare.
Where each item is reported
- Form 4797: the §1245 recapture (Part III, then Part II) and §1231 gain on business property.
- Form 6252: the installment portion, in the year of sale and every year a payment arrives.
- Form 8594: the allocation, filed by both buyer and seller.
- Schedule B: the interest you receive.
IRS Pub. 537 has a full sale-of-a-business example, and Topic 705 summarizes the basics. Our installment sale depreciation recapture article covers the recapture layer in more depth.
If part of your price is an earnout, see earnout tax treatment for how contingent payments are reported.
Both sides report the price allocation on Form 8594.
Bottom line
Seller financing a business spreads only the gain on eligible assets, mainly goodwill and real estate. Inventory and equipment recapture are taxed in the year of sale, and the cash at closing is taxed at the same gross profit percentage as the note. The allocation you sign decides most of the tax, so negotiate it with the same care as the price. Then size the note, and protect it, as a lender would.
Questions to ask your CPA
- How should the price be allocated among the asset classes, and what does each allocation do to my year-one tax?
- How much of the gain is §1245 recapture that I cannot defer?
- Given the cash at closing, how much gain actually rides on the note?
- Is my gain nonpassive, and does the 3.8% net investment income tax apply to any of it?
- Should the consulting or noncompete payments be separate from the sale price?
- If the buyer pays off the note early or defaults, what happens to the deferred gain?
- Would a stock sale instead of an asset sale change the answer, and does §1202 apply to my shares?
