Section 197 Amortization of Intangibles: How Buyers Write Off Goodwill, Customer Lists, and Non-Competes Over 15 Years

Imagine you just paid $5 million to acquire a small manufacturing business. The hard assets — equipment, inventory, real estate — appraise at $2 million. So where did the other $3 million go? Into the seller's brand, customer relationships, trained workforce, and the goodwill that makes the business worth more than the sum of its tangible parts.

That $3 million is not lost to the tax code. It is sitting on your balance sheet as an intangible asset. And thanks to Internal Revenue Code Section 197, you can deduct it — slowly, predictably, and almost mechanically — over the next 15 years.

This single provision quietly drives the economics of nearly every small-business and middle-market asset acquisition in the United States. Get it right and you unlock a steady stream of ordinary deductions that boosts after-tax cash flow for over a decade. Get it wrong — by triggering the anti-churning rules or misclassifying assets on Form 8594 — and you can lose deductions entirely or land in a multi-year dispute with the IRS.

Here is what every buyer, seller, and finance professional needs to understand about Section 197 before signing an asset purchase agreement.

What Section 197 Actually Does

Before 1993, the tax code was a mess on intangibles. Some intangibles could be amortized if you could prove they had a determinable useful life. Goodwill, famously, could not be amortized at all — once you paid for it, the cost just sat on the buyer's books forever, with no deduction until the asset was eventually sold or written off.

Section 197 swept that uncertainty away. Congress chose a single, uniform answer: take the cost of any qualifying intangible acquired in connection with a trade or business, divide it by 180 months, and deduct that amount each month for 15 years. No useful-life analysis. No appraisal disputes. No fights over whether goodwill is really an asset.

The deduction is automatic and ratable. Start the clock in the month the intangible was acquired. End it 180 months later. Whether the customer list churns out in year three or the goodwill keeps generating cash flow for thirty years, the tax treatment is identical.

This trade-off — predictability in exchange for sometimes-arbitrary timing — is the heart of Section 197.

The Eight Categories of Qualifying Intangibles

Section 197 sweeps in a remarkably broad list. To qualify, the intangible must generally be acquired by the buyer in connection with the acquisition of a trade or business (or a substantial portion of one). Once that test is met, the following all amortize over 15 years:

1. Goodwill

The classic Class VII asset on Form 8594. Goodwill is the residual purchase price left over after every other asset has been valued — the premium a buyer pays because the business is more valuable as a going concern than as a pile of disassembled parts.

2. Going Concern Value

Closely related to goodwill, going concern value is the value of having a business that is already operating — vendors lined up, processes running, revenue arriving. It is sometimes separated from goodwill in valuations, but for Section 197 purposes the treatment is identical.

3. Workforce in Place

A trained, recruited, and integrated workforce is itself an intangible asset. You did not pay for individual employment contracts, but you paid for the value of having a team ready to operate the business on day one. That value amortizes over 15 years.

4. Information Base

Business books and records, operating manuals, customer files, technical manuals, training programs, and similar information bases all qualify. If it is documented knowledge transferred from seller to buyer, it generally falls here.

5. Patents, Copyrights, Formulas, Processes, Designs, Patterns, Know-How

Note the timing trade-off here. A patent might have only 8 years of legal life remaining when you buy it, but Section 197 forces you to amortize over 15 years anyway. Conversely, perpetual know-how that might benefit the business for 30 years also gets the 15-year treatment.

6. Customer-Based Intangibles

Customer lists, customer relationships, customer contracts, and similar items. For service businesses, SaaS companies, and subscription businesses, this is often the largest intangible by dollar value after goodwill itself.

7. Supplier-Based Intangibles

The favorable position the seller has built with key suppliers — favorable contract terms, exclusive arrangements, supply commitments. Less common than customer intangibles but treated the same.

8. Government Licenses, Permits, Franchises, Trademarks, and Trade Names

Liquor licenses, taxi medallions, FCC licenses, franchise agreements, registered trademarks, and trade names all live here. So do covenants not to compete entered into in connection with the acquisition of a business — these are explicitly named in the statute even though they look like contracts, not "assets."

What Section 197 Does Not Cover

Just as important as the list of qualifying intangibles is the list of items Congress carved out. Section 197 does not apply to:

• Interests in a corporation, partnership, trust, or estate. Buy stock, not assets, and there is no Section 197 amortization.
• Interests in land. Real estate has its own rules.
• Financial contracts. Futures, foreign currency contracts, notional principal contracts, and similar instruments.
• Off-the-shelf computer software. Software that is publicly available, sold under a nonexclusive license, and not substantially modified is excluded. It is depreciated over 36 months under a different provision.
• Self-created intangibles, with a critical exception. If you develop a trademark or customer relationship in the ordinary course of running your business, the costs are not amortized under Section 197. But if you acquire that same intangible as part of buying a trade or business, it is amortizable. The acquisition context is what matters.
• Interests in films, sound recordings, video tapes, books, and similar property that are subject to specialized depreciation regimes.
• Leases of tangible property. A lease of equipment is not a Section 197 intangible.
• Mortgage servicing rights and certain other financial intangibles that have their own statutory regimes.

The two carve-outs that trip up buyers most often are off-the-shelf software and self-created intangibles. A company that built its own proprietary customer database in-house cannot suddenly amortize the "value" of that database when it dresses it up as an intangible — there was no acquisition. But the moment a buyer acquires that same database as part of an asset purchase, it converts to a Section 197 intangible for the buyer.

How Section 197 Plays With Form 8594

Section 197 does not exist in isolation. When a buyer and seller close an asset acquisition, both parties must file Form 8594 — the Asset Acquisition Statement Under Section 1060 — and they must allocate the purchase price across seven classes of assets using the residual method.

The residual method works through the classes in order, with Section 197 intangibles concentrated in the last two:

• Class I: Cash and cash equivalents
• Class II: Actively traded personal property and certificates of deposit
• Class III: Accounts receivable and certain debt instruments
• Class IV: Inventory
• Class V: All other assets (most tangible business assets including equipment and real estate)
• Class VI: Section 197 intangibles other than goodwill and going concern value
• Class VII: Goodwill and going concern value

You allocate the purchase price to Classes I through V at fair market value, then assign whatever is left to Classes VI and VII (with the residual within VI-VII going to Class VII goodwill).

This matters for two reasons. First, Class VI intangibles often need to be separately identified and valued — buyers and sellers must agree on what the customer list is worth, what the non-compete is worth, what the trade name is worth — even though all of them amortize on the same 15-year schedule. Second, the buyer and seller are required to report consistent allocations to the IRS. If they file inconsistently, both parties become audit magnets.

For sellers, the allocation has real consequences too. Allocations to Class V tangibles can produce ordinary income via depreciation recapture, while allocations to Class VII goodwill produce long-term capital gain. Buyers and sellers therefore have opposite incentives, and the negotiation often happens at the same table as the purchase price itself.

The Pooling Rule and Why It Matters

Here is a rule that frequently surprises new buyers: Section 197 treats all qualifying intangibles acquired in a single transaction as a single, indivisible pool for tax purposes.

You do not get to amortize the customer list over its expected useful life of 7 years and the trademark separately over the trademark's renewal cycle. Every Section 197 intangible from the acquisition shares the same 15-year amortization schedule, regardless of its true economic life.

The pooling rule extends further. If you later abandon or dispose of one intangible from the pool — say the customer list dries up after 5 years — you generally cannot recognize a loss on that disposition. The unamortized basis of the lost intangible is reallocated to the surviving intangibles in the same pool, and amortization continues. Only when you dispose of all the Section 197 intangibles acquired in the transaction can you recognize a loss.

This is why buyers should be cautious about valuing individual intangibles aggressively in the purchase price allocation. Front-loading the customer list to capture economic reality does not accelerate the deduction, and locking up the basis in a doomed intangible just shifts it to the rest of the pool.

The Anti-Churning Rules — A Trap for the Unwary

When Congress enacted Section 197 in 1993, it knew taxpayers would try to "create" amortizable intangibles by transferring pre-existing goodwill from one related party to another. Imagine the owner of a closely held company selling the company's goodwill to a newly formed corporation she also owned. Suddenly the goodwill — which had no tax basis and no amortization — would magically become a freshly acquired Section 197 intangible eligible for 15-year write-off.

To shut this down, Congress added the anti-churning rules in Section 197(f)(9). At a high level, the anti-churning rules deny Section 197 amortization for intangibles that:

• Were held or used at any time during the transition period (July 25, 1991 to August 10, 1993) by the taxpayer or a related party, and
• Were acquired from a related party who continues to use the intangible, or in a transaction whose principal purpose is to avoid Section 197's requirements.

For purposes of these rules, relatedness is defined more broadly than usual. Section 197 substitutes a "more than 20 percent" ownership threshold for the usual "more than 50 percent" tests under Sections 267(b) and 707(b). So family members, partnerships, and entities with as little as 21% common ownership can be tagged as related.

The anti-churning rules continue to be a trap for the unwary in three common scenarios:

1. Spin-offs and reorganizations where the same controlling group continues to use the intangibles before and after the transaction.
2. Estate-planning transfers between family members or family-owned entities.
3. Private equity rollovers where the seller retains a meaningful equity stake in the buying entity and the original team continues to operate the business.

Any time the same hands continue to touch the same intangibles after the deal, the anti-churning rules deserve a careful look before the closing documents are signed.

A Worked Example

Let's make this concrete. Suppose your company acquires the assets of a regional distribution business for $10 million. After working through the residual method, the Form 8594 allocation comes out as follows:

Class	Description	Amount
III	Accounts receivable	$1,000,000
IV	Inventory	$2,000,000
V	Equipment, vehicles, real estate	$3,500,000
VI	Customer list ($1.2M), non-compete ($300K), trade name ($200K)	$1,700,000
VII	Goodwill and going concern value	$1,800,000
	Total	$10,000,000

The Class VI and Class VII assets together — $3.5 million — are all Section 197 intangibles. They amortize together over 15 years (180 months) starting in the month of acquisition.

Annual amortization deduction: $3,500,000 ÷ 15 = $233,333 per year.

That deduction reduces the company's ordinary income, year after year, for 15 years. At a 25% effective federal-plus-state tax rate, the after-tax cash flow benefit is about $58,000 per year, or roughly $875,000 over the life of the amortization. That is real money — often the deciding factor between an asset deal and a stock deal from the buyer's perspective.

Common Mistakes Buyers and Sellers Make

After watching deals close for years, the same Section 197 mistakes show up over and over.

Mistake 1: Treating self-created assets as amortizable. A founder bringing intangibles into a new entity she controls cannot suddenly turn yesterday's self-created customer relationships into today's 15-year deduction. Without an acquisition of a trade or business from an unrelated party, there is no Section 197.

Mistake 2: Sloppy Form 8594 filings. Buyer and seller frequently file inconsistent allocations because their accountants never coordinated. The result is two simultaneous audit triggers. Always exchange and reconcile Form 8594 before either party files.

Mistake 3: Overlooking the anti-churning rules. Mid-market private equity deals with rollover equity, family business succession plans, and intra-group restructurings should all be screened for anti-churning exposure before deal terms are locked.

Mistake 4: Trying to accelerate amortization on a "useless" intangible. That non-compete that the seller signed but immediately retired into Florida? Still amortizes over 15 years. The pooling rule means you cannot abandon it and accelerate the deduction.

Mistake 5: Forgetting that software is special. Off-the-shelf software bundled into a business acquisition gets pulled into the Section 197 pool. Off-the-shelf software acquired in a standalone purchase gets 36-month depreciation. The difference comes down to whether assets constituting a trade or business changed hands.

Mistake 6: Ignoring state conformity. Most states conform to Section 197, but a handful (notably California, New Hampshire, and Pennsylvania for older transactions) have their own twists. Always confirm state treatment matches federal treatment before relying on the after-tax deal economics.

Why Section 197 Matters for Sellers, Too

Buyers love Section 197 because it converts a chunk of the purchase price into ordinary deductions. Sellers feel the symmetric effect on the other side of the table.

When a seller receives consideration allocated to Class VII goodwill, the gain is typically long-term capital gain — taxed at preferential rates. Consideration allocated to a covenant not to compete, however, is ordinary income to the seller (even though it is a Class VI Section 197 intangible to the buyer). Consideration allocated to inventory is ordinary income; consideration allocated to equipment can trigger depreciation recapture as ordinary income.

The result is a structured negotiation. Buyers push to allocate more value to a covenant not to compete (still 15-year amortization for them, but ordinary income for the seller they have already squeezed on price). Sellers push back, lobbying for the maximum possible allocation to goodwill. Both sides have to live with whatever Form 8594 they ultimately sign.

Smart deal lawyers and accountants negotiate the allocation alongside the headline price — and they write the agreed allocation into the purchase agreement before signing.

Bookkeeping for Section 197 Intangibles

Once the deal closes, the buyer's job is to track the intangible basis cleanly for the next 15 years. That sounds simple, but it requires discipline.

A typical post-closing book-tax workflow includes:

1. Set up a separate asset register for the Section 197 pool. Each acquired intangible should be tracked with its date of acquisition, original allocated value, amortization rate (1/180 per month), and remaining unamortized basis.
2. Run book amortization separately from tax amortization if the business uses GAAP. Under ASC 350, customer relationships and similar finite-lived intangibles get an estimated useful life that may be shorter than 15 years, and goodwill is not amortized at all — it is tested for impairment. This creates persistent book-tax differences.
3. Roll the schedule forward each month and record the deduction in tax workpapers. A spreadsheet works for a single deal, but companies with multiple acquisitions should automate.
4. Document the allocation methodology, including any valuation reports for individual intangibles, in case the IRS later challenges the Form 8594 filing.
5. Re-evaluate the pool only at disposition or impairment. Section 197 does not allow you to revisit the allocation later, so the time to get it right is at closing.

For founders and small-business owners, the entire workflow above lives or dies on whether the underlying books are clean. If your chart of accounts cannot distinguish "Goodwill from 2026 Acquisition of XYZ Co." from "Goodwill from prior acquisitions," your 15-year amortization schedule will be a fiction. Detailed, version-controlled bookkeeping is what makes the tax math actually work.

How This Connects to Your Broader Tax Strategy

Section 197 sits at the intersection of three big tax-strategy themes: structuring acquisitions, managing book-tax differences, and timing deductions.

On structuring: the choice between an asset deal and a stock deal is often dominated by Section 197. A buyer doing a stock deal inherits the seller's basis in everything — including a stepped-up goodwill basis of approximately zero. A buyer doing an asset deal gets a fresh 15-year amortization on every dollar of purchase price allocated to intangibles. For closely held businesses with material intangible value, that single difference can swing the deal economics by 20% or more.

On book-tax differences: companies that acquire multiple businesses end up with sprawling intangible registers where book and tax bases diverge dramatically. Tracking these differences is a major deferred-tax-liability driver and a frequent audit area.

On timing: the 15-year schedule means deductions arrive slowly. A buyer with a strong early year of cash flow and a weaker outlook cannot accelerate Section 197 amortization to match. Plan accordingly when structuring purchase price, earnouts, and rollover equity.

Keep Your Acquisition Books Audit-Ready From Day One

Section 197 amortization is one of the few tax provisions where the deductions are highly mechanical — but only if the underlying records are clean. Every dollar of intangible basis needs to be traceable to the closing balance sheet, the purchase price allocation, and the original Form 8594. Spreadsheets get out of sync. Acquired companies' books rarely match the buyer's chart of accounts. And by year three or four, the institutional memory of how the allocation was set is often gone.
