Disposal of Intangible Assets: Basis, Recapture, and Reporting

The federal tax treatment for disposal of intangible assets turns on three questions: what your adjusted basis is at the time of the transaction, whether the asset is a capital asset or a business asset in your hands, and how much amortization you already deducted. The gain equals what you received minus your adjusted basis. Any portion of that gain matching prior amortization deductions is recaptured as ordinary income; the rest may qualify for capital gain treatment. Losses are ordinary in many cases, but a specific rule disallows the loss entirely when you dispose of one intangible from a group purchase while keeping the others.

Start With Adjusted Basis

Every calculation begins with adjusted basis, the number that decides whether you have a gain or a loss. Under Section 1011, basis starts with what you paid for the intangible, including purchase price, legal fees, and registration costs.¹ You then subtract every amortization deduction you claimed or were entitled to claim while holding it.

Most business intangibles acquired as part of a business purchase fall under Section 197 and amortize on a straight line over 15 years starting the month of acquisition, regardless of the asset’s actual useful life.² A customer list bought for $75,000, held five years with $5,000 of annual amortization, has an adjusted basis of $50,000 at the time of disposal.

The gain or loss is what you realize minus that adjusted basis. Amount realized includes cash received, the fair market value of any property or services from the buyer, and any liabilities the buyer takes on. Sell the $50,000-basis customer list for $65,000 in cash while the buyer assumes a $5,000 liability, and you realized $70,000, producing a $20,000 gain. Sell it for $40,000 and you have a $10,000 loss, subject to the rules below on whether that loss is actually deductible.p>

How the Gain Is Taxed

Character depends on how you held the asset and how you got it.

Held for Investment: Capital Asset Rules

Intangibles held for investment rather than used in a trade or business are generally capital assets under Section 1221.³ Held more than a year, gain is long-term capital gain, taxed at rates below ordinary income rates.⁴ Held a year or less, it’s short-term and taxed like wages. Section 1221 excludes property used in a trade or business that’s subject to amortization, which pushes those assets into Section 1231.

Used in a Business: Section 1231

Intangibles used in a trade or business and held more than one year fall under Section 1231.⁵ Section 1231 nets all qualifying transactions for the year. If the net is a gain, it’s treated as long-term capital gain. If the net is a loss, it’s treated as ordinary and can offset any type of income, including wages and business profits. A $30,000 gain on a trademark and a $10,000 loss on a franchise agreement net to a $20,000 long-term capital gain; flip the numbers and you have a $20,000 ordinary loss.

Self-Created Intangibles

Creating the intangible yourself generally produces a worse tax result than buying one. Section 1221(a)(3) excludes patents, inventions, designs, secret formulas, and processes from capital asset treatment when held by the person whose efforts created them, and the same exclusion follows the asset if it passes to someone with a carryover basis from the creator.³ Gain on those assets is ordinary income. Self-created musical compositions and copyrights in musical works are a carved-out exception and can still qualify as capital assets.

Amortization Recapture

Even when a gain would otherwise qualify as capital, part of it gets pulled back into ordinary income. Section 197 intangibles are treated as Section 1245 property for recapture, so gain up to the total amortization you previously deducted is recharacterized as ordinary income.⁶ Only gain above that amount can get capital treatment.

Take a franchise agreement bought for $60,000, amortized by $24,000, sold for $70,000. Adjusted basis is $36,000, total gain is $34,000. The first $24,000 (matching prior amortization) is ordinary; the remaining $10,000 can qualify for capital gain treatment. Recapture applies to the lesser of the gain or total amortization deducted, so if the gain is smaller than cumulative amortization, the entire gain is ordinary.

The Loss Trap on Grouped Section 197 Intangibles

This is the rule that catches business owners off guard. When you acquire multiple Section 197 intangibles in the same transaction and later dispose of one at a loss while keeping the others, Section 197(f)(1) disallows the loss.² The disallowed amount is instead added to the adjusted basis of the remaining Section 197 intangibles from the same purchase.

This comes up often in business acquisitions where the purchase price gets split among goodwill, a customer list, a covenant not to compete, and a trade name. If the noncompete expires worthless after three years but you still hold the goodwill and customer list, you cannot write off the remaining basis. It rolls into the surviving intangibles and comes back over time through their continued amortization. The loss becomes deductible only when the last Section 197 intangible from that original acquisition is disposed of. Some buyers structure separate transactions where possible to avoid this outcome.

Abandonment and Worthlessness

Not every disposal is a sale. An abandonment loss under Section 165 requires you to show ownership, intent to abandon, and an affirmative act giving up the asset.⁷ Letting a patent lapse by not paying maintenance fees can qualify if you can document a deliberate choice. Courts look for concrete evidence of intent, such as written communications with advisors or formal notices to business partners. An abandonment loss on a business intangible is generally ordinary, so it offsets any type of income.

The Section 197(f)(1) disallowance rule applies to worthlessness too, not only to sales. If a Section 197 intangible becomes worthless while you still hold others from the same acquisition, the loss is not deductible; its basis shifts to the surviving intangibles.²

No Like-Kind Exchanges for Intangibles

Section 1031 no longer offers a deferral option here. Since January 1, 2018, Section 1031 applies only to real property.⁸ Swapping a patent for another patent, or a trademark for a different trademark, does not defer any gain. Every disposal of an intangible is a fully taxable event.

Installment Sales

When payments come in over more than one year, the installment method under Section 453 may let you spread the gain across the years payments are received.⁹ Two limits matter. When the intangible is sold as part of a larger business sale, the price must be allocated across all assets, and the installment method applies separately to each qualifying asset; inventory cannot use it. The recapture portion of any gain, the ordinary-income piece tied to prior amortization, is recognized in the year of sale rather than spread over the payment period.

Reporting the Disposal

Business intangibles are reported on IRS Form 4797, Sales of Business Property, showing gross sales price, adjusted basis, total amortization claimed, and acquisition and sale dates.¹⁰ Form 4797 handles both the recapture computation and the Section 1231 netting: recapture flows through Part III, and the Section 1231 calculation happens in Part I. Any resulting net long-term capital gain moves to Schedule D of Form 1040 and combines with your other capital gains and losses for the year.¹¹

Final figures end up on Form 1040 for individuals or Form 1120 for corporations. Installment sales require Form 6252 for each year payments are received. The IRS cross-references numbers across these forms, so the figures need to match.
