Seller financing means the seller takes a promissory note for part of the purchase price instead of cash at closing. It widens the buyer pool, typically supports a higher headline price, and qualifies the deferred portion for installment reporting, so tax on that gain is paid as principal is collected. The interest on the note is ordinary income, and the note must carry a stated rate at least equal to the applicable federal rate or the tax code will recharacterize part of the principal as interest anyway.

What Carrying the Note Buys the Seller

Three things, in order of how much they usually matter.

Price. A buyer who does not have to raise the full amount from a lender can pay more, and sellers who finance 20 to 40 percent of the price commonly realize a higher total than an all-cash deal would have produced. The premium is not free money, it is compensation for taking credit risk, but it is compensation the seller can actually price.

Buyer pool. Bank financing for the purchase of a privately held business is constrained, and a large share of qualified operators cannot close without seller paper. Refusing to carry a note removes those buyers from the process entirely.

Yield. A secured note on a business the seller knows intimately, at a rate above what the same money earns in a bond portfolio, is a reasonable asset to hold. Sellers who are otherwise going to sit in cash for a year after closing should compare the note rate to what the proceeds would actually earn.

How the Payments Are Taxed

Every payment splits into three parts, and each part has a different rate.

  • Return of basis. Not taxed.
  • Gain. Taxed at capital gain rates as principal is collected, using the gross profit ratio fixed at closing. The mechanics are set out in the installment sale guide.
  • Interest. Ordinary income in the year received, at rates up to 37 percent, and potentially subject to the 3.8 percent net investment income tax.

That rate difference creates an obvious temptation: state a low interest rate, raise the price, and convert ordinary income into capital gain. The code anticipated this, and the rules that stop it are the most important technical content on this page.

Imputed Interest and the Applicable Federal Rate

If a note does not carry adequate stated interest, Sections 483 and 1274 impute it. The benchmark is the applicable federal rate, published monthly by the IRS in short-term, mid-term, and long-term versions depending on the note's term. Where the stated rate falls below the applicable rate, a portion of each payment is recharacterized as interest, which increases ordinary income and reduces the capital gain, precisely reversing what the seller was trying to achieve.

Under Section 1274 the recharacterization is handled as original issue discount, which is worse than simply losing the rate arbitrage, because original issue discount accrues into income on a constant yield basis whether or not cash is received. A seller can end up reporting interest income in a year the buyer paid nothing.

The practical rule is to state a rate at or above the applicable federal rate for the term, document it in the note, and negotiate price on its own terms. A commercially reasonable rate is usually well above the federal rate anyway, since the seller is taking subordinated credit risk on a small business.

Structuring the Note So It Is Actually Collectible

The tax analysis is worthless if the money does not arrive. Terms that matter, roughly in order:

  • Security. A first or second lien on the business assets, perfected by a UCC-1 filing, and where possible a pledge of the equity so a default returns control of the company rather than a claim against it.
  • Personal guarantee. From the individual buyer, not only the acquisition entity, and supported by a personal financial statement obtained during diligence.
  • Covenants. Limits on additional debt, distributions, and compensation while the note is outstanding, with financial reporting at least quarterly.
  • Acceleration and cure. A short cure period and a clear acceleration trigger, so a slow decline does not become an unsecured position by the time anyone acts.

Two structures deserve specific caution. A note secured by a standby letter of credit can retain installment treatment if the letter is genuinely standby and cannot be drawn absent default. Proceeds placed in an escrow the seller can reach are generally treated as received at closing, which defeats the deferral entirely. The difference between the two is drafting.

Earnouts and Contingent Payments

Where part of the price depends on future performance, the payments are contingent and the basis recovery rules under the installment regulations apply. If a maximum price is stated, basis is recovered ratably against that maximum. If only a term is stated, basis is recovered ratably over the term. If neither is stated, basis recovery is spread over fifteen years, which is the worst outcome and entirely avoidable by stating a cap.

Earnouts also raise a character question. Amounts tied to the seller's continued employment can be recharacterized as compensation, taxed at ordinary rates and subject to payroll tax. Keeping the earnout tied to business performance rather than the seller's service, and paying separately and reasonably for any transition work, keeps the two categories apart.

When Not to Carry Paper

Seller financing is a poor fit when the seller needs the full proceeds immediately for a diversification plan or a charitable structure, when the buyer's operating experience does not support the risk, when the business depends on the seller's relationships in a way that makes post-closing performance genuinely uncertain, or when the seller's estate plan cannot absorb an illiquid note held at death.

The honest framing is that carrying a note is an investment decision the seller is making in a business they are choosing to leave. It is often a good one, at a good rate, with better information than any other lender has. It is not a good one when the reason the buyer cannot get financing is that the business does not support it.

Running the Numbers Against an All-Cash Deal

The comparison sellers rarely make is between a lower all-cash price and a higher price with a note attached. Consider a business where the all-cash offer is $4,500,000 and the financed alternative is $5,000,000 with $1,500,000 carried over five years at 8 percent.

ElementAll cash at $4.5M$5.0M with a $1.5M note
Cash at closing$4,500,000$3,500,000
Principal collected later$0$1,500,000
Interest collected over 5 years$0Roughly $325,000
Gain recognized at closingFull70 percent
Credit risk carriedNone$1,500,000

The financed structure produces roughly $825,000 more in total consideration and defers tax on a portion of the gain, in exchange for taking subordinated risk on $1.5 million. Whether that is a good trade depends entirely on the buyer and the business, and it is a question the seller is better placed to answer than any outside lender.

The reason to write it out is that the two offers are usually presented as though the higher number is simply better, or the cash number simply safer. Neither is true without the arithmetic.

Key Takeaways

  • Seller notes widen the buyer pool and usually support a higher total price.
  • Principal carries capital gain at the fixed gross profit ratio; interest is ordinary income.
  • State a rate at or above the applicable federal rate or interest gets imputed anyway.
  • Original issue discount can force interest income in a year no cash was received.
  • Perfect the security interest and take a personal guarantee before worrying about tax.
  • State a maximum price on any earnout so basis recovery is not spread over fifteen years.

Frequently Asked Questions

What interest rate should a seller note carry?

At minimum the applicable federal rate for the note's term, published monthly by the IRS. Commercially, subordinated seller paper on a small business typically carries a materially higher rate, and pricing it at the federal minimum leaves money on the table without any tax benefit in exchange.

Is the interest I receive subject to the 3.8 percent surtax?

Interest income is net investment income, so it is exposed once modified adjusted gross income crosses the threshold. The capital gain portion of each payment may be treated differently depending on whether the seller materially participated in the business, which is a separate analysis under Section 1411.

Can I sell the note later?

Yes, but selling or otherwise disposing of an installment obligation accelerates the remaining deferred gain into the year of disposition. The same is true of using the note as loan collateral under the pledging rule. Sellers who expect to need liquidity should size the note accordingly rather than plan to monetize it.

How much of the price should I finance?

There is no universal answer, but 10 to 30 percent is the common range in privately held business sales, with the seller note subordinated to any bank debt. The right number is the amount the seller can afford to lose entirely without changing their post-sale plan.

Does a seller note affect how much the buyer can borrow?

Usually it helps. Lenders often treat properly subordinated seller paper with a standstill provision as part of the equity layer, which improves the buyer's coverage ratios and can enlarge the senior loan. That is one reason a seller carrying 15 percent frequently unlocks a deal that would not have closed at any price, and it is worth raising with the buyer's lender directly rather than negotiating the note in isolation.

What happens to the note if I die before it is repaid?

The remaining deferred gain is income in respect of a decedent, so the heirs continue reporting gain as payments arrive rather than receiving a basis step-up on that portion. An estate tax deduction is available where estate tax was paid on the note. Sellers with long notes should confirm the estate plan accounts for an illiquid asset with a built-in tax liability.
