How to Account for Goodwill in Sale of Business: ASC 350, IRC 197 and Form 8594 (2026)

Learning how to account for goodwill in sale of business is the single most expensive accounting question a private-company seller will face, because the same dollar of purchase price can be taxed at 20 percent or 37 percent, amortized over 15 years or sit on the buyer’s balance sheet forever, depending entirely on how it is classified at closing. On a typical $10 million asset deal, BVR’s 2025 Control Premium Study reports goodwill ranges from 35 to 60 percent of total enterprise value across lower middle market transactions, which means the rules in ASC 350 and IRC Section 197 routinely decide whether the seller nets $5.2 million or $6.1 million after tax.

What This Actually Means

Goodwill, in a sale context, is the residual of purchase price over the fair value of identifiable net assets. It is not a single asset you can point to. It is the math left over after you assign value to inventory, equipment, customer lists, non-compete agreements, trade names, and every other identifiable line on the balance sheet. The accounting follows two parallel tracks that almost never agree with each other: the book track under U.S. GAAP (Accounting Standards Codification Topic 350) and the tax track under Internal Revenue Code Section 197.

The book track is what the buyer’s auditor cares about. Under ASC 350-20, goodwill is an indefinite-lived intangible asset, which means the buyer does not amortize it. Instead, the buyer tests it for impairment at least annually, and more often if a triggering event occurs (FASB ASC 350-20-35-30). If impaired, the buyer takes a non-cash hit to earnings. That hit can be significant. KPMG’s 2025 U.S. Goodwill Impairment Report tracked $42.9 billion in goodwill impairments across U.S. public companies in 2024, the highest non-pandemic figure on record.

The tax track is what the IRS cares about, and it is where the seller’s wallet actually gets touched. Under IRC Section 197, goodwill acquired in connection with the acquisition of a trade or business is a Section 197 intangible, amortized straight-line over 15 years by the buyer. For the seller, goodwill sold in an asset transaction generally produces capital gain (taxed at federal rates of 15 to 20 percent plus the 3.8 percent net investment income tax), not ordinary income (taxed up to 37 percent). The character difference, capital versus ordinary, is often a seven-figure swing on a middle-market deal.

Mismatching these two tracks is where most owners get hurt. The buyer wants more allocated to goodwill (15-year amortization deduction). The seller usually wants more allocated to goodwill too (capital-gain treatment). That alignment is one of the rare points of natural agreement in an M and A negotiation, but only if the seller’s entity structure does not impose a hidden penalty. If the target is a C-corporation, more goodwill can mean more double tax, which we cover later.

The Six Things You Need to Understand

1. Book Treatment Under ASC 350: No Amortization, Annual Impairment Test

ASC 350-20-35-3A through 35-3G lays out the impairment regime that has governed private-company goodwill accounting since FASB Accounting Standards Update 2014-02 created the simplified alternative, and which was extended in 2017 to allow a one-step quantitative test. Public companies and private companies that have not elected the alternative test goodwill at the reporting-unit level. Private companies that elected the alternative amortize goodwill straight-line over 10 years and only test for impairment when a triggering event occurs.

For the typical buyer doing GAAP reporting, the workflow is:

• Step 0 (optional qualitative test). The buyer can perform a qualitative assessment of whether it is more likely than not that fair value is below carrying amount (ASC 350-20-35-3F). If the answer is no, no further testing is required for that period.
• Step 1 (quantitative test). If the qualitative bypass is not used, or if the qualitative test indicates possible impairment, the buyer compares the reporting unit’s fair value to its carrying amount including goodwill. Any excess of carrying amount over fair value is recorded as an impairment loss (ASC 350-20-35-2 through 35-13, as amended by ASU 2017-04).
• Triggering events for interim testing. ASC 350-20-35-30 requires interim testing on the occurrence of an event or circumstance that would more likely than not reduce the fair value of a reporting unit below its carrying amount. PwC’s 2025 Business Combinations Guide lists the most common triggers as: sustained share-price decline, loss of a key customer, regulatory action, a change in the carrying amount of net assets, or a recession-driven revenue contraction.

The practical takeaway for sellers: every dollar of goodwill on the buyer’s books is a dollar at risk of being written off later. That does not affect your closing proceeds, but it does affect how the buyer values your goodwill in negotiation. Sophisticated strategic buyers will resist any goodwill allocation that is not defensible to their auditor.

2. Tax Treatment Under IRC Section 197: 15-Year Straight-Line Amortization

Section 197 was added to the Internal Revenue Code by the Omnibus Budget Reconciliation Act of 1993, specifically to end the constant litigation over whether goodwill and other intangibles were amortizable. Before 1993, the IRS routinely disallowed goodwill amortization because the asset had no determinable useful life. The Section 197 fix was to declare a flat 15-year recovery period for all qualifying intangibles, including goodwill, going concern value, customer-based intangibles, supplier-based intangibles, licenses, permits, trade names, trademarks, covenants not to compete, and franchises.

Mechanically, the buyer of an asset sale gets a deduction equal to (purchase price allocated to goodwill) divided by 180 months. On a $5.5 million goodwill allocation, that is roughly $30,556 of monthly amortization, or $366,667 of annual deduction. At a 21 percent federal corporate rate, the after-tax value of that deduction stream is approximately $1.155 million, present-valued at a 7 percent discount rate (estimate, based on a standard DCF of the deduction tail).

Section 197 amortization does not apply to stock acquisitions. If the buyer purchases the stock of a target without making a Section 338(h)(10) or Section 336(e) election, the buyer takes a carryover basis in the target’s assets, and any historical goodwill on the target’s books remains non-deductible. This is one of the reasons buyers usually prefer asset deals, and one of the reasons sellers should not concede to a stock sale without compensation for the lost tax benefit.

3. Anti-Churning Rules Under Section 197(c)(2)

The anti-churning rules of IRC Section 197(c)(2) are the most expensive landmine in goodwill accounting, and they exist specifically to stop a related-party seller from converting non-amortizable goodwill into amortizable goodwill through a paper transaction. If the seller and buyer are related parties (defined in Section 197(f)(9) and the regulations as more than 20 percent common ownership), and the goodwill was held by anyone in the related group prior to August 10, 1993, the buyer is denied the Section 197 amortization deduction. The buyer takes a 15-year hold on goodwill that produces zero tax shield.

Treasury Regulation 1.197-2(h) is the operating manual for the anti-churning rules and runs more than 40 pages. The practical traps:

• Family-member buyouts. A son buying his father’s S-corp will commonly hit the anti-churning rules if the father held the company before 1993 and retains any ownership post-close.
• Sales to entities the seller still partly owns. If the seller rolls equity into the buyer’s acquisition vehicle and ends up with more than 20 percent of the post-close company, anti-churning can apply to the entire goodwill allocation, not just the rolled portion.
• Step transactions. Treasury Reg 1.197-2(h)(6) gives the IRS authority to collapse a multi-step transaction into a single related-party sale.

The fix, when available, is to ensure the seller’s post-close ownership of the buyer entity is 20 percent or less, or to structure as a fresh start through a complete sale to an unrelated party. The deal team must run the anti-churning analysis before the LOI is signed.

4. Character of Gain: Personal Goodwill vs. Enterprise Goodwill

The Tax Court’s decision in Martin Ice Cream Co. v. Commissioner, 110 T.C. 189 (1998), is the foundational case for splitting goodwill between the corporation (enterprise goodwill) and the individual owner (personal goodwill). Arnold Strassberg, a Martin Ice Cream shareholder, had built supermarket relationships in his individual capacity. When the supermarket distribution rights were sold, the Tax Court held that the goodwill attributable to Strassberg’s personal relationships was his property, not the corporation’s, and could be sold by him directly to the buyer outside the corporate transaction.

The split is worth real money on a C-corporation sale. Corporate goodwill is taxed twice: once at the corporate level (21 percent federal) and again at the shareholder level when the proceeds are distributed (15 to 23.8 percent). Personal goodwill is taxed once, as long-term capital gain to the individual (15 to 23.8 percent including the net investment income tax).

Two follow-on cases sharpened the doctrine:

• Bross Trucking, Inc. v. Commissioner, T.C. Memo 2014-107. The Tax Court allowed Chester Bross to sell personal goodwill in his trucking business directly to a successor entity owned by his sons. The court emphasized the absence of a non-compete or employment agreement binding Bross to the corporation, which kept the goodwill in his hands.
• Norwalk v. Commissioner, T.C. Memo 1998-279. Two accountants left their professional corporation taking their client relationships. The Tax Court held the client relationships were personal goodwill of the individuals, not corporate goodwill of the PC, because the PC had no employment or non-compete agreements with them.

The Norwalk and Bross facts tell you what to do prospectively. To preserve a personal-goodwill argument, the seller should avoid signing broad non-competes or employment agreements with the corporation in the years leading up to a sale, and the seller’s personal relationships and reputation must be documented as the actual source of recurring revenue.

5. The C-Corp Double-Tax Trap (and the F-Reorg and 338(h)(10) Workarounds)

If the target is a C-corporation and the deal is structured as an asset sale, every dollar of goodwill (other than personal goodwill carved out under Martin Ice Cream) gets taxed twice. Run the math on a $5.5 million corporate goodwill allocation:

• Corporate-level tax: $5,500,000 times 21 percent = $1,155,000.
• Net to shareholder: $4,345,000.
• Shareholder-level tax on distribution (assume 23.8 percent including NIIT): $1,034,110.
• Net to shareholder after both layers: $3,310,890.
• Effective rate: 39.8 percent on the goodwill component.

Compare to a pass-through (S-corp or LLC) asset sale, where the same $5.5 million of goodwill is taxed once at 23.8 percent and the seller nets $4,191,000. The double-tax hit on a C-corp goodwill allocation is approximately $880,000 on every $5.5 million.

The most common workarounds are:

• F-reorganization. For S-corp targets that have potential historical S-election issues, an F-reorg under Section 368(a)(1)(F) creates a clean S-corp holding structure and lets the buyer purchase the original entity as a disregarded LLC, getting asset-sale tax treatment (including Section 197 goodwill amortization) while the seller takes single-layer S-corp tax. Frequency in lower middle market deals has risen significantly, with KPMG’s 2025 M and A Tax Quarterly reporting roughly 38 percent of S-corp transactions over $25 million using an F-reorg structure.
• Section 338(h)(10) election. Available for S-corp or consolidated-group C-corp targets. The buyer purchases stock but the deal is treated as an asset sale for tax purposes. The buyer gets the Section 197 goodwill amortization, and the seller pays one layer of tax. The election must be filed jointly on IRS Form 8023 within 8.5 months of the closing month.
• Section 336(e) election. Similar effect to 338(h)(10) but unilateral by the seller, and available for sales to non-corporate buyers (private equity buyers, individuals). Often the better choice when the buyer is an LLC or partnership.

For a stand-alone C-corp target with no holding structure, none of these workarounds is available, and the seller must either accept the double tax or push for personal-goodwill treatment under Martin Ice Cream to peel goodwill off the corporate return.

6. Form 8594 Allocation Reporting and the Matched-Allocation Rule

IRS Form 8594 (Asset Acquisition Statement Under Section 1060) is the document where the buyer and seller report the purchase price allocation. Both parties must file Form 8594 with their tax returns for the year of the sale, and the allocation amounts must match. Treasury Regulation 1.1060-1 dictates the seven-class residual allocation method:

The matched-allocation rule of Section 1060(a)(2) requires the buyer and seller to use the same allocation. If they file inconsistent Forms 8594, the IRS treats it as a red flag and audit risk goes up sharply. The Form 8594 instructions (revised December 2024) added an explicit question requiring the parties to disclose if the allocation was amended after a closing settlement, which closes a common dodge where one party tried to re-allocate post-close.

Negotiation tactics for the seller:

• Push fixed-asset values to their book value (lower) and customer-list values to a low end of the defensible range. Both of those leave more residual for goodwill (Class VII), which gets capital-gain treatment.
• Resist large non-compete allocations. Non-competes are Class VI Section 197 intangibles, but for the seller they are ordinary income, not capital gain. A buyer pushing a $500,000 non-compete is asking you to pay roughly $85,000 of extra federal tax (37 percent ordinary minus 20 percent capital, times $500,000).
• Negotiate the allocation in the LOI or the definitive purchase agreement. The worst time to negotiate is after closing.

Worked Example: $10 Million Asset Sale, $5.5 Million Goodwill

Apex Industrial Services, Inc., is a fictional but representative target: an S-corporation HVAC and mechanical services contractor in Ohio with $2.1 million of EBITDA, founded by Tom Apex in 2008. A strategic buyer offers $10 million for the assets. Closing date is March 31, 2026. The Form 8594 allocation, negotiated in the definitive purchase agreement, breaks down as follows:

Of the $5.5 million in goodwill, Tom Apex’s accountant carves out $1.2 million as personal goodwill on the basis of Tom’s personal relationships with the top 8 commercial property managers who together account for 64 percent of recurring revenue. The personal-goodwill carveout is documented with a separate Personal Goodwill Purchase Agreement between the buyer and Tom individually, and supported by a third-party valuation showing Tom’s customer relationships were never assigned to the corporation and are not protected by any pre-existing non-compete.

Seller’s tax math (S-corp pass-through, single layer):

• Ordinary income components (AR, inventory, depreciation recapture on equipment of approximately $400,000, non-compete): roughly $1.5 million. Federal tax at 37 percent plus 3.8 percent NIIT not applicable: $555,000.
• Long-term capital gain components (customer list, trade name, $4.3 million corporate goodwill, $1.2 million personal goodwill): $7.45 million. Federal tax at 20 percent plus 3.8 percent NIIT: $1,773,100.
• Total federal tax: approximately $2,328,100.
• Net cash to seller (pre-state): approximately $7,671,900.

Buyer’s tax math:

• Class V equipment ($1.2 million): MACRS depreciation over 5 to 7 years.
• Class VI intangibles ($2.15 million): Section 197 amortization, $11,944 per month, $143,333 annually.
• Class VII goodwill ($5.5 million, or $4.3 million corporate plus $1.2 million personal, both amortizable as Section 197 in the buyer’s hands): $30,556 per month, $366,667 annually.
• Total annual Section 197 amortization: approximately $510,000. At a 25 percent blended federal-state rate, that is $127,500 of annual after-tax cash benefit for 15 years.

ASC 350 book treatment on the buyer’s books:

• Goodwill of $5.5 million is recorded as an indefinite-lived intangible.
• The buyer’s reporting unit fair value (Apex Industrial integrated into the buyer’s mechanical services segment) is tested annually, with the next test scheduled for December 31, 2026.
• The buyer elects the qualitative bypass under ASC 350-20-35-3F for the first year on the basis of stable customer retention, positive EBITDA trend, and no triggering events.

Common Mistakes

1. Skipping the Anti-Churning Analysis on Family Sales

Family-owned businesses often roll equity to the next generation or sell to a family-owned holding company. If the seller retains more than 20 percent of the post-close entity, the Section 197(c)(2) anti-churning rules can wipe out 15 years of goodwill amortization for the buyer. The deal team must run the analysis before structure is locked in.

2. Treating Personal Goodwill as Automatic

Martin Ice Cream is not a free pass. The IRS routinely challenges personal-goodwill carveouts that are not documented. The seller needs a separate purchase agreement with the buyer, a contemporaneous valuation, evidence of personal customer relationships, and (critically) the absence of a binding pre-existing non-compete with the corporation. Without all four, the carveout collapses on audit.

3. Filing Mismatched Forms 8594

Both buyer and seller file Form 8594 with their tax returns for the closing year. The allocation must match exactly. Mismatched forms are a near-automatic audit flag and the IRS will impose its own allocation under Section 1060(a). The fix is simple: agree on the allocation in the purchase agreement and exchange final Form 8594 drafts before filing.

4. Letting the Buyer Push a Large Non-Compete Allocation

Buyers love non-compete allocations because they are Class VI Section 197 intangibles, fully amortizable. Sellers should hate them because non-compete proceeds are ordinary income, not capital gain. On a $500,000 non-compete allocation, the seller pays roughly $85,000 of extra federal tax versus the same dollar allocated to goodwill. Push back hard.

5. Forgetting About State Tax

The federal analysis is only half the picture. Many states tax capital gain at ordinary rates (Massachusetts, Minnesota, Oregon, California). A seller in California adds roughly 13.3 percent to the federal rate on the entire goodwill allocation. Tax counsel should run the state-by-state numbers before allocation is finalized.

6. Ignoring the C-Corp Double-Tax Trap Until It Is Too Late

By the time an LOI is signed on a C-corp target, the structuring options are largely fixed. F-reorgs and Section 338(h)(10) elections require advance planning. The right time to evaluate the entity structure is 18 to 36 months before the sale, not 30 days before closing.

Timeline: Goodwill Accounting Process From Term Sheet to Tax Return

1. Pre-LOI (Day -120 to Day 0). Tax counsel runs entity-structure analysis (C-corp vs S-corp vs LLC). Anti-churning analysis if seller retains rollover equity. Initial allocation framework drafted.
2. LOI signed (Day 0). LOI should reference the intended allocation methodology in general terms (e.g., “consistent with the residual method under Section 1060”) without locking in dollar amounts.
3. Due diligence (Day 1-60). Third-party valuation of identifiable intangibles (customer list, trade name, non-compete) by a qualified appraiser. Personal-goodwill analysis if applicable.
4. Definitive purchase agreement (Day 60-90). Final allocation negotiated and attached as an exhibit. Personal Goodwill Purchase Agreement signed separately if used.
5. Closing (Day 90-120). Funds flow. Allocation locked. Section 338(h)(10) election (if applicable) prepared for filing.
6. Post-closing (Day 120-365). Buyer records purchase accounting under ASC 805 / 350. Seller and buyer prepare matched Forms 8594 for tax-year returns. Section 338(h)(10) election filed on Form 8023 within 8.5 months of closing.
7. Year 1 anniversary. Buyer’s first annual goodwill impairment test under ASC 350-20-35-30. Buyer’s first full year of Section 197 amortization deductions reported on Form 4562.

Frequently Asked Questions

What is the difference between book goodwill and tax goodwill?

Book goodwill follows ASC 350: indefinite life, no amortization, tested for impairment annually. Tax goodwill follows IRC Section 197: 15-year straight-line amortization, no impairment test. The same dollar of goodwill can have very different book and tax bases over time, which creates deferred-tax accounting entries on the buyer’s balance sheet for the life of the asset.

How is goodwill taxed when you sell a business?

For asset sales, goodwill is generally taxed as long-term capital gain to the seller (federal 15 to 20 percent plus 3.8 percent net investment income tax) if the seller is an individual or pass-through entity. For C-corporation asset sales, goodwill is taxed twice: once at the corporate level (21 percent) and again at the shareholder level on distribution (15 to 23.8 percent). For stock sales, the goodwill component is absorbed into the overall capital gain on the stock and gets capital treatment, but the buyer does not get to amortize the goodwill unless a Section 338(h)(10) or 336(e) election is made.

Can goodwill be allocated to the seller as personal goodwill?

Yes, under Martin Ice Cream v. Commissioner, 110 T.C. 189 (1998), goodwill attributable to an individual owner’s personal relationships, reputation, and skill can be sold by the owner directly to the buyer outside the corporate transaction. The carveout requires a separate purchase agreement, a contemporaneous third-party valuation, and the absence of a binding non-compete with the corporation. Personal goodwill is most valuable on C-corporation sales, where it bypasses the corporate-level tax layer entirely.

Does the buyer amortize goodwill on a stock sale?

Not by default. In a pure stock sale, the buyer takes a carryover basis in the target’s assets and cannot amortize the existing goodwill. The buyer can elect Section 338(h)(10) (jointly with the seller, for S-corps and consolidated-group C-corps) or Section 336(e) (unilaterally by the seller, for sales to non-corporate buyers) to treat the stock sale as a deemed asset sale for tax purposes, which gives the buyer Section 197 amortization on the goodwill component.

What happens if the buyer impairs the goodwill after closing?

A post-closing impairment under ASC 350-20-35-2 is a non-cash charge to the buyer’s earnings. It does not affect the seller’s tax position or the seller’s proceeds in any way. The buyer reduces the carrying value of goodwill on the balance sheet and recognizes the impairment loss in the income statement. The buyer’s Section 197 tax amortization is unaffected by book impairment because the tax basis is independent of the book carrying value.

Do both buyer and seller have to file Form 8594?

Yes. Under Section 1060(b) and Treasury Reg 1.1060-1, both parties must file Form 8594 with their income tax returns for the year of the sale, and the allocation amounts must match. Failure to file or filing inconsistent forms can result in a $250 penalty and, more importantly, draws IRS scrutiny. The form is also required to be re-filed if any subsequent adjustment to the purchase price increases or decreases the allocation by more than a de minimis amount.

How CT Acquisitions Approaches Goodwill in a Sale

CT Acquisitions is a buyer-paid M and A advisor. That model matters here because the goodwill allocation is one of the points in the deal where the buyer’s interests and the seller’s interests can be aligned, but only if someone is doing the math from the seller’s side of the table before the LOI is signed. Most owners do not get that math run for them until the buyer’s tax advisor sends over a draft Form 8594 with the wire instructions, and by then the negotiation window has closed.

Our sell-side process includes a pre-LOI structuring memo that covers the entity-structure decision (pass-through versus C-corp consequences), the personal-goodwill carveout opportunity under Martin Ice Cream, the anti-churning analysis if any rollover equity is on the table, the F-reorg or 338(h)(10) workaround if the target is a C-corp or has S-election risk, and a draft Form 8594 allocation built around the seller’s after-tax outcome. The buyer pays our fee at closing, so the seller gets that work done at no cost. That is the buyer-paid advisor model: we sit on your side of the table, but the buyer funds it.

What to Do Next

Goodwill accounting in a business sale is too expensive to leave to the buyer’s accountant. The same $10 million transaction can leave the seller with $7.7 million or $5.5 million in their pocket depending on entity structure, personal-goodwill carveout, anti-churning analysis, and Form 8594 allocation. The decisions that drive that gap are made before the LOI, not at closing.

CT Acquisitions runs the goodwill model for every seller we represent before the term sheet is signed. We coordinate with your tax counsel on the entity-structure decision (F-reorg, 338(h)(10), 336(e), or accept-the-double-tax), we document the personal-goodwill carveout under the Martin Ice Cream standard, we model the buyer’s Section 197 amortization to anchor purchase-price negotiation, and we draft the Form 8594 allocation as an exhibit to the definitive purchase agreement. The result is a sale where the after-tax proceeds match what you saw on the offer memo, not what shows up after a surprise audit two years later.
