- §1256(b)(2)(B) has expressly named equity categories, so an equity perp’s argument starts closer to the statute than a crypto perp’s commodity-swap analogy. We do not conclude an equity perp is an equity swap — no authority addresses these products.
- The real equity-specific risk is §1259. Shorting a perp against appreciated shares you own can be a constructive sale — taxed as if you sold, with the holding period reset. Crypto perp traders have no equivalent exposure.
- The interaction is awkward: the “it is a swap” argument that keeps a perp out of §1256 is what makes it an offsetting notional principal contract inside §1259.
- A statutory escape exists — close before the 30th day after year end and hold the appreciated position for 60 days after. Both legs required.
- Do not carry the crypto wash-sale answer across. Crypto escapes §1091 because it is not a security; an equity perp references securities, and no authority we found addresses the pattern.
- No dividends, no qualified dividend rate, no holding period on an underlying share. Non-US persons should ask about §871(m) dividend equivalents.
- Market context: a reported $201bn Q3 2026 notional on one venue and 315 reported HIP-3 markets by late October 2026 — figures that move weekly and are not asserted as current.
Perpetual contracts referencing individual stocks and equity indices went from a curiosity to a real market during 2026. Reported Q3 2026 notional volume in stock, ETF and index perps on Hyperliquid alone was $201 billion, and by late October 2026 ten reported HIP-3 operators were running 315 markets between them. Ostium added Nasdaq-fed equity perps on Arbitrum in May 2026.
The tax discussion has not kept up, and the gap is not where people assume. Most writing treats “perps” as one thing. An equity-referencing perp raises three questions a bitcoin perp simply does not — and one of them can accelerate tax on stock you were not planning to sell.
If you hold appreciated shares and short a perp on the same stock, you may have triggered a constructive sale under IRC §1259 — taxed as if you sold the shares at fair market value, with the holding period reset. Crypto perp traders have no equivalent exposure, because §1259 runs on stock, debt instruments and partnership interests. Carrying a crypto-perp mental model onto an equity perp is how this gets missed.
The §1256 answer is the same conclusion, reached more directly
Our perps framework explains why perps fail IRC §1256 on two independent grounds. For an equity perp, the second ground is stronger and more explicit.
§1256(b)(2)(B), added by Dodd-Frank in 2010, removes a list of swap-type instruments from §1256. The categories in that list are consistently identified across independent professional sources as covering interest rate, currency, basis, commodity, equity and equity index swaps, credit default swaps, caps, floors and similar agreements. Two of the named categories are equity categories. The exclusion operates regardless of whether the contract would otherwise be a regulated futures contract and regardless of venue, so it reaches a listed, exchange-traded equity perp as well as an on-chain one.
That changes which named exclusion is even in play — the point our hub makes about the underlying. For a bitcoin perp you are reasoning by analogy to a commodity swap. For a perp on a single stock or an equity index, there are expressly named equity categories to reason about instead, and the analogy is a shorter one.
We are not saying an equity perp is an equity swap. No ruling, regulation or decision addresses these products, and the statutory categories were written decades before them. What we are saying is narrower: the identity of the underlying decides which exclusion you would be arguing about, and for equity-referenced contracts that argument starts closer to the statutory language than it does for crypto.
The first ground applies as usual too: the venue prong. As far as we can establish, the on-chain venues listing equity perps hold none of the §1256(g)(7) designations, and an on-chain protocol typically has no registrant that could. That is a public-record point about registration status, not a view about the products.
Treasury's 2011 swap-exclusion proposals would treat a contract that is a notional principal contract under Treas. Reg. §1.446-3(c) as not a §1256 contract — but they treat currency swaps as NPCs while not extending the same treatment to swaps referenced to a commodity or equity index. So for an equity-index perp the NPC route is less available than people assume, and the exclusion rests on the statutory swap list itself rather than the NPC definition. Those regulations remain proposed, and we have found no evidence they were finalised. They are useful for reading Treasury's instinct, not as a rule to rely on.
Constructive sales: the risk that is specific to equity perps
Not only perps. The same §1259 question arrives by a different route for a tokenized share, where the definition’s reach over debt instruments can matter.
IRC §1259 treats a taxpayer as having sold an appreciated financial position at fair market value when they enter certain offsetting transactions. An appreciated financial position includes stock with unrealized gain. The triggering transactions in §1259(c)(1) include:
- a short sale of the same or substantially identical property;
- an offsetting notional principal contract with respect to the same or substantially identical property;
- a futures or forward contract to deliver the same or substantially identical property;
- acquiring the property when the taxpayer already holds an appreciated short position in it.
Here is the uncomfortable interaction. The argument that keeps a perp out of §1256 is that it is a swap — economically a notional principal contract. That is the same characterisation that makes it an offsetting notional principal contract for §1259 when it is written against stock you already own at a gain. You cannot comfortably argue “it is a swap, so no 60/40” and also “it is not a swap, so no constructive sale.” Whichever way the characterisation goes, one of the two rules is engaged.
If §1259 applies, the consequences are not trivial: gain is recognised as though you sold at fair market value on that date, the holding period restarts from then, and losses are not recognised under these rules. A position you intended to hold for long-term rates can be reset to short-term.
There is a statutory escape. A transaction that would otherwise be a constructive sale is disregarded if it is closed before the 30th day after the close of the taxable year and the taxpayer holds the appreciated position throughout the 60-day period beginning on the date the transaction is closed. That is a real planning tool and a real trap — miss either leg and the exception fails.
Certainty level: INTERPRETIVE. No ruling, regulation or decision we could find applies §1259 to a perpetual contract specifically, and one secondary source reports that there are no Treasury regulations under §1259 at all. We are not asserting that any particular equity perp is an offsetting notional principal contract. We are saying the fact pattern sits squarely inside the one §1259 was written for, and a trader holding appreciated stock while shorting a perp on it should get advice before putting the position on, not in April.
Wash sales: do not carry the crypto answer across
If you are weighing a loss you intend to claim, the wash-sale calculator is the quickest way to see whether the replacement timing puts it at risk.
Our crypto tax page states that crypto is currently not subject to wash-sale rules, and our futures page states that §1256 contracts are exempt. Both are correct. Neither tells you the answer for an equity perp, and the reasoning behind each is why.
Crypto escapes §1091 because §1091 applies to “stock or securities” and crypto is treated as property that is not a security. An equity perp is not stock either — but it references stock, and §1091 reaches more than shares: it covers contracts and options to acquire or sell stock or securities, and it turns on whether what you acquired is substantially identical to what you sold at a loss.
A cash-settled perp confers no right to acquire the shares, which is a genuine argument that it falls outside the provision. But a trader who sells AAPL at a loss and immediately establishes long AAPL perp exposure is doing the thing the rule exists to prevent, and we have found no authority addressing that pattern. Treat it as unsettled and fact-specific, not as the automatic “no” that applies to crypto.
The same caution applies to the straddle rules in §1092, which can defer losses on offsetting positions in personal property and are not limited to securities.
What you do not get, which affects the numbers
- No dividends. You have price exposure, not share ownership, so there is no dividend to receive and no qualified dividend rate to claim. Where a contract's funding mechanism economically reflects dividend expectations, that shows up in funding, not as dividend income — and funding has its own unresolved treatment.
- No long-term holding period on the underlying. There is no share with a basis and a clock. Whatever the contract's character turns out to be, it is not a long-held share.
- No shareholder attributes. No voting, no dividend reinvestment, and nothing that depends on holding stock — qualified small business stock treatment under §1202, for instance, requires actual stock.
- Non-US persons: §871(m) is worth asking about. That regime can impose withholding on dividend-equivalent amounts arising from equity-linked derivatives. Whether and how it applies to a particular on-chain equity perp, and who would withhold, is not something we have seen addressed. If you are not a US person, raise it with an adviser rather than assuming the absence of a withholding agent means the absence of a rule.
Funding payments still cut against you
Everything our hub says about funding applies here unchanged. At least three treatments are in use — ordinary at each settlement, a basis or amount-realised adjustment, or deferral to close — and no guidance picks one. None is the default.
The asymmetry is the material risk: funding received is ordinary income under the conservative view, while funding paid is deductible only by someone carrying on a trade or business. For an investor it is a miscellaneous itemized deduction, which OBBBA made permanently non-deductible. An equity perp book that lost money can still generate tax, which makes trader-versus-investor status the whole bill rather than a label.
Records that nothing will reconstruct for you
- Each funding settlement, with direction, amount and timestamp. Under the conservative reading each one is an income or expense event; under the others it adjusts basis. You cannot apply any of the three without the series.
- Every position in a stock you also hold outright, with open and close dates. This is the §1259 and §1091 evidence, and it is the record most likely to be missing.
- Whether a §1259 exception was relied on: the close date, and proof you held the appreciated position for the full 60 days afterwards.
- Which market operator listed the contract. On frameworks where third parties deploy their own markets, the operator is not necessarily the venue you logged into, and that can matter for who reports what.
- Exports taken while you still have access. On-chain venues publish no 1099, and access to a deprecated market or a drained protocol is not guaranteed.
What we are not asserting
On sources, the same caveat our hub carries applies here. Outbound access to irs.gov and the statutory text is blocked from the environment this page was researched in. Section numbers and the structure and effect of the provisions discussed — §1256(b)(2)(B), §1259(c)(1), §1091, §1092, §871(m) — are consistently identified across independent professional sources, which is why we are willing to name them. No statutory or regulatory wording on this page is quoted as though we had read it, and where exact words would have to carry the argument we describe the provision’s effect instead.
We are not asserting: the contract form, counterparty entity or governing jurisdiction of any venue or market operator; that any venue holds or lacks a particular registration beyond the present-tense public-record point above; that any specific equity perp is or is not an offsetting notional principal contract for §1259; that §1091 does or does not reach a given fact pattern; that §871(m) applies to any particular contract; or that any volume, market count or product list on this page is current. Market counts and operator rosters on these frameworks change weekly, and at least one report describes an October 2026 incident draining an RWA perp venue through key compromise rather than contract failure — which is a records and loss-characterisation problem of its own.
No platform here issues tax forms as far as we can establish, and the regulations that would have imposed broker reporting on decentralised front ends were repealed in April 2025 by a Congressional Review Act resolution. The absence of a form became more certain, not less.
Where this fits
- Perpetual futures taxes — the framework: both §1256 arguments, the four candidate treatments, funding, and the venue table.
- Index futures taxes — the contrast case. An exchange-listed index future on a designated contract market does get §1256 and the 60/40 split. Same underlying, different wrapper, different answer. The §1256 calculator prices that 60/40 blend on the listed contract, which is the size of the gap — it is not a calculation to run on the perp.
- Futures taxes and §1256 — why the venue and the margining system are the whole test.
- The wash sale rule — what “substantially identical” has meant where it has been tested.
- Stock trading taxes — if you hold the shares as well, that side runs on ordinary rules.
Holding shares and shorting a perp on them?
That is the fact pattern §1259 was written for, and the 30-day / 60-day exception has to be set up before year end rather than discovered after it. A specialist who files trader returns can look at the actual positions.

Do stock perpetuals get the 60/40 Section 1256 split?
Almost certainly not, on two independent grounds. The venue prong fails on undesignated on-chain venues. And Section 1256(b)(2)(B) removes swap-type instruments from Section 1256 regardless of venue, with expressly named equity and equity index categories, so an equity perp’s argument starts closer to the statutory language than a crypto perp’s commodity-swap analogy. We do not conclude that an equity perp is an equity swap: no ruling, regulation or decision addresses these products, and the categories were written decades before them.
Can shorting a stock perpetual trigger a constructive sale of shares I own?
It is a real risk and should be checked before the position goes on. IRC Section 1259 treats you as selling an appreciated financial position, which includes stock with unrealized gain, when you enter an offsetting transaction such as a short sale of substantially identical property or an offsetting notional principal contract. The argument that a perp is a swap, which is what keeps it out of Section 1256, is the same characterisation that makes it an offsetting notional principal contract for Section 1259. No authority we could find applies Section 1259 to a perpetual contract specifically, so this is interpretive rather than settled.
Is there an exception to the constructive sale rules?
Yes. A transaction that would otherwise be a constructive sale is disregarded if it is closed before the 30th day after the close of the taxable year and the taxpayer holds the appreciated position throughout the 60-day period beginning on the date the transaction is closed. Both legs are required, so it has to be planned rather than discovered afterwards.
Do wash sale rules apply to stock perpetuals?
Unsettled, and the crypto answer does not carry across. Crypto escapes Section 1091 because the provision applies to stock or securities and crypto is not a security. An equity perp is not stock either, but Section 1091 also reaches contracts and options to acquire or sell stock or securities and turns on whether the replacement is substantially identical. A cash-settled perp confers no right to acquire shares, which is a genuine argument against application, but we have found no authority addressing a trader who sells shares at a loss and immediately takes long perp exposure to the same stock.
Do I receive dividends on a stock perpetual?
No. You have price exposure rather than share ownership, so there is no dividend and no qualified dividend rate to claim. Where a contract's funding mechanism economically reflects dividend expectations, that appears in funding rather than as dividend income, and funding has its own unresolved treatment.
How are funding payments on an equity perp taxed?
The same way as on any perp: unresolved. At least three treatments are in use, ordinary income or expense at each settlement, a basis or amount-realised adjustment, or deferral to close, and no guidance picks one. The asymmetry is the material risk, because funding received is ordinary income under the conservative view while funding paid is deductible only in a trade or business. For an investor it is a miscellaneous itemized deduction, which OBBBA made permanently non-deductible.
Does a stock perpetual platform send me a 1099?
As far as we can establish, no on-chain perp venue issues one, and the regulations that would have imposed broker reporting on decentralised front ends were repealed in April 2025 by a Congressional Review Act resolution. That makes the absence of a form more certain rather than less, and it makes your own exports the only record. Section 61 requires the income to be reported whether or not a form arrives.
I am not a US person. Does anything extra apply?
Possibly. The Section 871(m) regime can impose withholding on dividend-equivalent amounts arising from equity-linked derivatives. Whether and how it reaches a particular on-chain equity perp, and who would act as withholding agent, is not something we have seen addressed. Do not treat the absence of a withholding agent as the absence of a rule; raise it with an adviser.
