Build something valuable with your own two hands, a patent, a copyright, a piece of software, and you would expect the profit on a sale to land at the lower long-term capital gains rate. For a specific set of intangibles, the tax code says no. The gain comes out as ordinary income, taxed at your regular rate, which can be a meaningfully bigger bite.
The direct answer: a Tax Cuts and Jobs Act provision strips capital asset status from certain self-created intangibles. When the creator sells one, the profit is ordinary income, not long-term capital gain. The rule is narrow, it reaches only a defined list of assets, and the result hinges almost entirely on one thing, who the tax code treats as the creator. Get that question right and you may keep capital gains treatment. Get it wrong, or never ask it, and you may hand the IRS more than you needed to.
Most of the confusion around this rule disappears once you stop asking "what kind of asset is this?" and start asking "whose effort does the law say produced it?" An asset created by your own personal efforts is treated very differently from the same asset created by an organization. So before classifying anything, pin down the creator. That single fact drives the rate.
When the following intangibles are held by the very person whose personal efforts produced them, the law denies capital asset status:
A patent you invented. An invention, model, or design you developed, whether or not it was ever patented. A secret formula or process you worked out. A copyright in work you authored. Any literary, musical, or artistic composition you created. And one that catches people off guard, letters, memos, or similar property that someone else prepared specifically for you, even though you did not write them yourself.
Sell any of these as the creator and the gain is ordinary income. That's the core of the provision.
A natural instinct is to drop the asset into an LLC or corporation before selling, hoping the entity gets cleaner tax treatment. For these specific intangibles, that move usually doesn't help, and the reason is a concept called substituted basis.
When you contribute one of these self-created assets to a partnership or a corporation in a tax-free transaction, the entity doesn't get a fresh start on basis. It steps into your shoes, inheriting the basis you had. And because the asset's basis traces back to the creator, the entity inherits the unfavorable character right along with it. A later sale by that partnership or corporation still throws off ordinary income or loss, not capital gain or loss. (If you want the foundation on why this carried-over figure matters so much, see our explainer on why tax basis is important.)
There's a wrinkle worth knowing if you operate as a C corporation. C corporations don't enjoy lower rates on long-term capital gains in the first place, so it's tempting to assume the capital-versus-ordinary label is irrelevant to them. It isn't. A C corporation can only deduct its capital losses against capital gains recognized in the same year. Whatever net capital loss is left over becomes a short-term capital loss that carries back three years and, to the extent still unused, forward five years. Anything you can't absorb within that window simply vanishes. So the classification still has teeth, even for a C corp.
Here's the part that opens up planning room. "Personal efforts" is the trigger, and under IRS regulations, you've contributed your personal efforts if you either directly helped create the asset or you directed and guided the people who did. For an individual working alone, that's clear-cut, and the asset is not a capital asset.
But what happens when a business entity is doing the creating? A long-standing IRS revenue ruling looked at a publicly traded C corporation and concluded that work produced by a large group of the company's employees was not the personal effort of the taxpayer. The upshot: that asset is a capital asset in the corporation's hands. The same logic should extend to a partnership, an LLC, or an S corporation that creates an asset through its people rather than through one individual's hands-on work.
In other words, the distinction between "I made this myself" and "my organization made this" can be the line between an ordinary-income sale and a capital-gain sale.
The code carves out two specific paths back to favorable treatment.
Transferred patents. A patent you invented generally isn't a capital asset under current law, but that can shift after certain transfers. Several IRS private letter rulings have concluded that when an inventor transfers a self-created patent to an LLC taxed as a partnership in exchange for membership interests, the inventor can still be treated as the patent holder. When the LLC later sells the patent, the inventor's slice of the gain may qualify for capital gains treatment under Section 1235, and the same result should apply on a transfer to a corporation. Keep in mind private letter rulings bind only the taxpayers who requested them, so treat this as a strategy to vet with your advisor, not a sure thing.
Music. If your personal efforts created a musical composition or a copyright in one, you can elect to treat it as a capital asset. That election also reaches a taxpayer whose basis in the work carries over from the creator, so a partnership or corporation that received the composition from the creating individual in a tax-free transaction can make the election and treat it as capital property.
Now the reassuring part for the typical business sale. Self-created intangibles that aren't on the restricted list keep their capital asset status. That covers most of what actually changes hands when a business is sold: customer-based intangibles like client and prospect lists, goodwill and going-concern value, your workforce in place, business books and records, operating systems, and supplier-based intangibles such as favorable supplier contracts, along with similar items.
One string is attached. For capital treatment to apply, the intangible has to rise to the level of "property." It clears that bar when it's more than a bare right to collect income you've already earned and it carries some of the hallmarks we associate with property, the capacity to appreciate in value being a classic one.
A few scenarios make the rule concrete.
A solo consultant selling the book of business. Say you run a one-person marketing consultancy as a single-member LLC that's treated as a sole proprietorship for tax purposes. You sell the firm, and the client list, which carries no tax basis but real value, goes with it. Client lists sit outside the restricted category, so yours is a capital asset and the long-term gain qualifies for favorable capital gains rates.
A multi-partner firm selling the same way. Now picture you and several other architects operating a practice as a professional LLC taxed as a partnership. The firm sells, and again the client list has no basis but significant value. It gets the identical treatment the solo consultant's list received, and the gain flows through to each partner's personal return at favorable long-term capital gains rates.
A studio that built copyrighted software. You and a handful of other developers create and copyright a game engine with substantial value, doing the work through an LLC taxed as a partnership. The software has no tax basis. Under the revenue ruling described earlier, the work can be treated as created by the LLC rather than by your personal efforts. So if the LLC sells the software after holding it more than a year, the gain qualifies as lower-taxed long-term capital gain and passes through to you and your co-developers.
Change two details and the answer changes with them:
Same software in every version. The structure, and who the law sees as the creator, sets the tax bill.
Certain self-created intangibles, patents, copyrights, and creative works among them, aren't capital assets when their creator sells them, so the gain is taxed as higher-rate ordinary income instead of as long-term capital gain. The encouraging counterweight is that most of the intangibles a business actually sells, client lists, goodwill, supplier relationships, can still qualify for capital treatment.
Because the outcome rides on who created the asset, how it's held, and how the sale is structured, smart planning and a deliberate allocation of the purchase price can shave real dollars off the tax when you sell a business or an intangible. The time to sort this out is before a deal is signed, while the structure can still be adjusted. If a sale is anywhere on your radar, schedule a free tax strategy session and we'll look at how your intangibles are classified and whether a different structure would serve you better.
Not when you're the creator selling your own work. Patents, copyrights, inventions, secret formulas, and literary, musical, and artistic works produced by your personal efforts are treated as non-capital assets, so the gain is ordinary income. Exceptions exist for transferred patents under Section 1235 and for an election available on musical works.
Generally yes. Client and customer lists, goodwill, going-concern value, and supplier-based intangibles fall outside the restricted category, as long as the intangible qualifies as property.
Often not. Contribute a self-created intangible in a tax-free transaction and the entity inherits your basis and the unfavorable character, so a later sale is still ordinary income. The exception is an asset genuinely created by an organization's people rather than by one individual, which can qualify as a capital asset. The structure and the facts decide it.
