Single Stock Perpetual Futures Taxes

Last Updated on November 12, 2026 by Patrick Camuso, CPA

Security futures, the Section 1256 exclusion, and broker reporting

Quick Answer

If a single stock perpetual future qualifies as a securities futures contract, Internal Revenue Code Section 1256(b)(2)(A) generally excludes it from the standard 60/40 capital gain regime. An exception exists for qualifying dealer securities futures contracts, subject to additional statutory requirements and character rules.

Section 1234B generally determines the character of gains and losses from the sale, exchange, or termination of securities futures contracts by reference to the underlying property. Capital treatment may apply to a qualifying contract referencing stock that would be a capital asset in the taxpayer's hands, although special rules apply to short positions, ordinary property transactions, and certain hedges.

The threshold classification remains contested. The CFTC has authorized single stock perpetuals as security futures, while challengers argue that contracts without an expiration or future delivery obligation are more appropriately regulated as security based swaps. A federal district court issued a preliminary assessment favorable to that challenge on November 3, 2026, but denied emergency relief.

No published IRS guidance directly addresses the complete tax treatment of these newly introduced equity perpetuals. Funding payments, contractual dividend adjustments, Section 871(m) withholding, trader elections, and broker reporting require separate consideration.

Single stock perpetual futures became available in the United States in November 2026, introducing a new class of equity derivatives with significant tax and regulatory questions. Kalshi's launch allows traders to maintain leveraged exposure to individual stocks without purchasing the underlying shares or rolling contracts at expiration. The Commodity Futures Trading Commission has treated these instruments as security futures, although that classification is already being challenged in federal court.

For tax purposes, the classification matters because Congress established specific rules for securities futures contracts. Section 1256 generally excludes them from its 60% long term and 40% short term capital gain treatment, while Section 1234B provides separate rules for the character of gains and losses. Periodic funding, dividend adjustments, and the treatment of positions held by professional traders introduce additional questions that existing guidance does not fully resolve.

The analysis must account for the actual contract, its regulatory status, the taxpayer's activities, and the transactions recorded throughout the position's life. Those distinctions also affect broker information reporting, withholding obligations, and the accounting records needed to support a return.

How Single Stock Perpetual Futures Work

On November 5, 2026, Kalshi announced the launch of single stock perpetual futures, providing price exposure to more than 50 publicly traded companies. The contracts allow traders to establish long or short positions without directly owning the referenced shares.

A perpetual futures contract has no scheduled expiration. Its value is linked to an underlying reference price, while periodic funding payments help maintain the relationship between the contract price and the underlying market. Traders can maintain positions as long as they satisfy the applicable margin and other contractual requirements, subject to exchange trading hours, liquidation procedures, and exceptional termination events.

Kalshi's published specifications provide that each standard single stock perpetual contract represents 0.02 shares of the referenced stock. Fifty contracts therefore represent the same directional price exposure as one share, before considering funding, fees, or other adjustments.

The exchange uses a margin system under which traders post collateral to support their positions. Initial margin establishes the required collateral when a position is opened, while maintenance margin requirements determine whether the position can remain open without additional funds. Kalshi Klear LLC provides central clearing, and the published product documentation identifies settlement times of noon and 4:00 p.m. Eastern, with funding calculated once daily at 4:00 p.m. Eastern.

Trading hours are also significant. Kalshi's equity perpetuals follow scheduled trading sessions rather than the continuous 24-hour trading commonly associated with cryptocurrency perpetuals. A position can remain outstanding while trading is closed, creating exposure to underlying stock price movements that cannot immediately be offset through the perpetual market.

These mechanics affect the accounting as well as the tax analysis. Price based settlements, funding payments, collateral movements, and corporate action adjustments must be identified independently. A change in the value of a margin account may reflect several different transactions, and the exchange's aggregate realized profit calculation does not necessarily measure taxable income.

The products also differ across exchanges. Coinbase Derivatives filed rules in September 2026 governing cash settled individual equity and exchange traded fund futures, including perpetual single stock contracts. Its published framework contains different provisions for dividend adjustments and funding. The contract specifications and governing venue therefore matter even where two instruments reference the same underlying stock.

Why the Security Futures Classification Determines the Tax Framework

The Securities Exchange Act of 1934 defines a security future by reference to a contract for the sale of a single security or a narrow based security index for future delivery. Section 1234B(c) incorporates that definition for federal income tax purposes.

Traditional securities futures contracts involve standardized positions referencing individual securities or qualifying indexes. The tax rules governing those contracts developed separately from the treatment of regulated commodity futures.

Single stock perpetuals create a classification question because their economic exposure continues indefinitely. A position does not ordinarily terminate through a scheduled delivery or expiration event. Instead, traders may close through offsetting transactions, while the contract uses ongoing price settlements and periodic funding.

The CFTC's position is that these instruments can qualify as security futures notwithstanding the absence of a conventional expiration date. On November 3, 2026, CFTC Chairman Michael S. Selig announced that equity perpetual futures could begin trading on designated contract markets that are also notice registered with the SEC for security futures products.

The regulatory approach has been challenged in Capital Markets Alliance Association v. Commodity Futures Trading Commission, No. 1:26-cv-09608 (S.D.N.Y.). The Capital Markets Alliance Association is the named plaintiff. Representatives of Cboe Global Markets, Citadel Securities, and Healthy Markets Association submitted declarations supporting its emergency relief application. The challenge concerns the CFTC's authorization of products involving KalshiEX, Coinbase Derivatives, and Bitnomial Exchange.

The association argues that indefinite equity linked contracts without a future delivery obligation fall outside the statutory definition of security futures and more closely resemble security based swaps. The CFTC maintains that the approved instruments can operate within the security futures regulatory framework.

In a November 3 order, Judge Valerie E. Caproni found that the plaintiff was likely to succeed on its claim that the CFTC exceeded its statutory authority. The court nevertheless denied the requested temporary restraining order because the association had not established sufficiently likely irreparable harm.

That ruling represents a preliminary judicial assessment. It does not constitute a final determination of the products' regulatory status, and it does not decide their income tax treatment.

The classification dispute has consequences beyond exchange regulation. Section 1234B applies specifically to securities futures contracts, and Section 1256 contains an express securities futures exclusion. If an instrument ultimately falls outside the security futures definition, those statutory provisions cannot simply be applied without reconsidering the contract's actual legal classification.

If a perpetual instead qualifies as an equity swap or similar agreement, Section 1256(b)(2)(B) presents an independent statutory exclusion. A determination that an instrument does not qualify as a securities futures contract would not, by itself, establish eligibility for Section 1256 treatment.

An alternative security based swap classification could introduce different timing, character, and reporting rules, including questions under the notional principal contract regulations. The applicable tax treatment would still need to be established from the Internal Revenue Code and relevant Treasury regulations rather than inferred solely from the regulatory outcome.

Section 1256 Generally Excludes Securities Futures Contracts

Section 1256 provides a specialized tax regime for certain regulated futures contracts, foreign currency contracts, nonequity options, dealer equity options, and dealer securities futures contracts.

Qualifying positions generally receive annual mark to market treatment. Open contracts are treated as sold for fair market value on the last business day of the taxable year, and recognized gains and losses generally receive a 60% long term and 40% short term capital allocation, subject to applicable exceptions.

However, Section 1256(b)(2)(A) expressly excludes securities futures contracts and options on those contracts unless they qualify as dealer securities futures contracts.

For an ordinary investor or proprietary trader, this exclusion can be decisive. Even where an equity perpetual trades on a CFTC designated contract market, uses variation margin, and otherwise resembles a regulated futures contract, its securities futures classification generally prevents application of the ordinary Section 1256 regime.

The exclusion does not depend on a separate IRS ruling identifying each newly listed contract. It follows from the statutory classification, provided the instrument actually qualifies as a securities futures contract.

Congress also established an exception for dealer securities futures contracts under Sections 1256(b)(1)(E) and 1256(g)(9). The exception requires specific statutory conditions, including qualifying dealer status and the nature of the dealing activity.

A proprietary trading firm does not become a securities futures dealer merely because it maintains high transaction volume, quotes two sided markets, operates automated strategies, or supplies liquidity to an exchange. Those activities may be relevant evidence, but the statutory dealer definition requires an independent analysis of the firm's capacity and transactions.

Even where the dealer securities futures exception applies, the resulting character is not necessarily an unmodified 60/40 allocation. Section 1256(f)(4) provides special short term capital treatment for certain gains and losses from dealer securities futures contracts allocable to limited partners or limited entrepreneurs.

For partnerships and trading firms with multiple owners, the dealer exception may therefore require both an entity level classification and an examination of the applicable owner level character provisions.

The broader Section 1256 analysis for perpetual futures involves different statutory considerations depending on whether the instrument references a security, commodity, currency, or another underlying asset. The securities futures exclusion prevents a conclusion about commodity perpetuals from being transferred automatically to equity perpetuals.

Section 1234B Provides the Principal Character Rules

Congress enacted Section 1234B specifically to address gains and losses from securities futures contracts.

Under Section 1234B(a)(1), gain or loss attributable to the sale, exchange, or termination of a securities futures contract generally receives the same character as the referenced property has, or would have, in the taxpayer's hands.

For an individual holding publicly traded corporate stock as an investment, that property ordinarily would be a capital asset. A qualifying securities futures contract referencing the stock may therefore produce capital gain or loss when the applicable transaction is recognized.

The provision also incorporates important limitations. Section 1234B(a)(2) excludes certain contracts involving ordinary property or identified hedging transactions, as well as income derived in connection with a contract that is otherwise treated as something other than capital gain from a sale or exchange.

The second limitation is relevant to perpetuals because a contract can generate payments while the principal position remains open. Section 1234B does not automatically classify every related funding payment, financing charge, or dividend adjustment as capital gain or loss.

Short positions also receive specific treatment. Under Section 1234B(b), capital gain or loss from a securities futures contract to sell property generally is treated as short term, subject to exceptions under Section 1233, Section 1092 regulations, and other applicable rules.

Accordingly, the tax character of a long equity perpetual position and a short position referencing the same stock may require different holding period and character analyses. The fact that a perpetual can remain open indefinitely does not mean a position held beyond one year automatically receives long term capital treatment.

Section 1234B(d) provides an additional statutory distinction. For purposes of the Internal Revenue Code, a securities futures contract is not treated as a commodity futures contract. This express rule reinforces Congress's decision to place securities futures within a separate tax framework.

These provisions establish a meaningful starting point for qualifying securities futures transactions. The actual recognition event still requires examination of the position's legal termination, any prior settlements, and other applicable tax provisions.

A completed offsetting trade may terminate an existing position, while an increase in an opposite direction position does not necessarily produce the same legal result. Partial closes, reversals, exchange directed liquidations, and corporate action terminations can also require different treatment depending on the governing contract and clearing rules.

For positions that fall outside Section 1234B, general gain recognition and character provisions, including Sections 1001, 1221, and potentially 1234A, may become relevant. Those provisions should be considered only after the applicable instrument classification and special statutory regimes have been determined.

Funding Payments, Margin, and the Timing of Tax Recognition

Kalshi's equity perpetuals use a funding mechanism intended to keep the contract price aligned with the underlying stock price. Funding is calculated daily, and the direction of the payment depends on whether the contract is trading at a premium or discount relative to the relevant reference price.

The resulting cash flow is separate from the trading fee charged to execute an order and from the change in value of the principal position.

For tax purposes, recurring funding can be analyzed under competing interpretations. One treats the payments as part of the overall economics of maintaining the derivative, potentially affecting the gain or loss determined under the governing contract regime. Another treats a legally separate periodic obligation as a distinct receipt or payment whose recognition and character depend on the relevant contractual and tax rules.

The treatment cannot be established solely from the fact that the exchange reports funding separately. The governing tax regime, payment rights, taxpayer's accounting method, and applicable deduction provisions all affect the analysis.

Similarly, the term funding does not independently establish interest expense. Interest characterization ordinarily requires a genuine indebtedness or other legally supportable financing arrangement. A payment that reverses between long and short holders according to market pricing may have financing like economics without necessarily satisfying that requirement.

The rules for notional principal contracts under Treasury Regulation Section 1.446-3 provide a separate framework for qualifying contracts. However, the regulation excludes bona fide futures contracts from its notional principal contract definition. The existence of periodic funding does not automatically make a perpetual future a notional principal contract for income tax purposes.

Margin and variation settlement introduce a related recognition issue.

Initial margin generally functions as collateral supporting contractual performance. Posting refundable margin ordinarily does not itself establish a deductible trading loss. Variation margin reflects changes in the value of the position, but its treatment depends partly on whether the relevant payment legally settles exposure or constitutes collateral subject to repayment rights.

The actual customer agreement matters because the legal relationship between the clearinghouse and its clearing members may differ from the relationship between an intermediary and its customer.

Where variation payments legally settle recognized price exposure, the subsequent closing transaction must account for amounts previously recognized. Where transfers instead constitute returnable collateral, the cash movement alone does not establish a taxable disposition.

The accounting must preserve those distinctions so that a taxpayer does not recognize the same economic gain through both interim variation settlements and the ultimate closing transaction.

Dividend Adjustments and Section 871(m) Withholding

Equity perpetuals can provide economic exposure to a company's stock without granting the holder ownership of the underlying shares. The trader ordinarily does not receive voting rights or actual corporate dividends in the capacity of a shareholder.

Nevertheless, distributions on the referenced stock affect the economics of the perpetual contract. Exchanges may address those effects through explicit cash adjustments, changes in contract valuation, or funding mechanics.

Kalshi's published equity perpetual documentation provides for cash adjustments when an underlying company pays ordinary or special dividends. Long holders receive the adjustment, and short holders pay the corresponding amount.

For example, assume a trader holds 100 standard Kalshi perpetual contracts referencing a particular stock. At 0.02 shares per contract, the position represents two shares of economic exposure.

If the company pays a $1 dividend per share and the exchange's applicable corporate action procedure produces a corresponding cash adjustment, the trader would receive $2.

The adjustment reflects the contractual economics of the derivative. It does not establish that the recipient owns two shares or has received an actual qualified dividend from the corporation.

For a U.S. taxpayer, the payment must be evaluated under the applicable contract and income character rules. Its recognition date also depends on when the contractual entitlement arises and is settled, rather than simply when the corporation declares a dividend.

Other venues may use materially different mechanics. Coinbase Derivatives' September 2026 published rule filing states that ordinary cash dividends generally do not trigger a separate adjustment. Instead, their economic effects are expected to be reflected through market prices and the funding mechanism. The filing provides different procedures for certain other corporate actions.

That difference has accounting and tax implications. A separately posted dividend adjustment and a dividend related change embedded in funding or contract value may require different records and legal analyses, even where the ultimate economic exposure is similar.

Section 871(m) and dividend equivalent payments

Section 871(m) introduces an additional issue for derivatives referencing U.S. equities, particularly where the recipient is a non-U.S. person.

The statute and Treasury Regulation Section 1.871-15 address dividend equivalent payments arising from certain transactions involving underlying U.S. securities. The regulation expressly includes futures contracts among the financial instruments that can constitute equity linked instruments.

A qualifying payment may be treated as a U.S.-source dividend equivalent, creating withholding obligations under the applicable provisions even though the recipient does not directly own the referenced shares.

For a single stock perpetual, the analysis may turn on the actual contractual exposure, applicable delta calculation, payment terms, and relevant testing time. The use of a linear payoff structure is important, but a contract's description as a perpetual or its stated share multiplier does not independently establish its regulatory delta.

The issue can also arise where dividend economics are incorporated into a funding mechanism instead of being reported as a separately identified dividend adjustment. The transaction must be evaluated under the substantive regulatory rules rather than the exchange's accounting label alone.

In October 2026, the IRS published Notice 2026-61, extending important transitional provisions under Section 871(m).

The notice continues the phased application of the rules through 2028, generally maintaining the operative focus on delta one transactions while deferring specified non delta one provisions for payments relating to transactions issued through 2028. It also extends certain good faith compliance standards and relief applicable to qualified derivatives dealers.

The transition provisions do not eliminate withholding requirements for covered transactions, and the anti abuse rule under Treasury Regulation Section 1.871-15(o) remains applicable.

For foreign trading firms, financial intermediaries, and withholding agents, Section 871(m) can therefore create documentation, withholding, and reporting obligations separate from the domestic income tax character of the trader's underlying contract gain or loss.

Broker Reporting and Form 1099-B

Securities futures contracts are expressly addressed in the federal broker information reporting regulations.

Treasury Regulation Section 1.6045-1 includes securities futures contracts within the relevant definitions of securities and reportable transactions. Section 1.6045-1(a)(14)(iv) identifies them as specified securities, while Section 1.6045-1(a)(15)(i)(F) addresses their treatment as covered securities for applicable transactions entered into in an account on or after January 1, 2014.

The regulation also treats qualifying closing transactions as sales for relevant reporting purposes.

However, the reporting rules contain their own definition of a securities futures contract under Section 1.6045-1(a)(18). That definition incorporates Section 1234B(c), limits the qualifying underlying asset to the stock category specified in the regulation, and includes the applicable effective date requirement.

Accordingly, the existence of securities futures reporting rules does not establish that every equity linked perpetual or ETF referenced derivative must receive identical Form 1099-B treatment.

The actual contract, reporting broker, customer account, transaction, and applicable exemptions must be considered.

For the newly launched equity perpetuals, traders should establish what tax documentation their intermediary will provide and whether the reported amounts include the relevant closing transactions, proceeds, adjusted basis, and other required information.

The treatment of funding and dividend adjustments may require additional reconciliation because those amounts can be recorded independently from the principal closing transactions.

A Form 1099-B is an important source of reporting information, but it does not independently determine the substantive tax character of the transactions reported on it. The taxpayer's reporting obligation remains governed by the applicable law, supported by the complete records.

This distinction becomes particularly relevant when a trading account contains multiple instrument categories. A platform may provide access to securities futures, commodity futures, event contracts, and digital assets through related accounts or interfaces. Each instrument may be subject to different tax and information reporting requirements.

Professional Trading Firms, Section 475, and Accounting Requirements

For professional traders and market makers, the classification of an individual equity perpetual is part of a broader tax and accounting analysis.

Section 475 can require or permit mark to market treatment for certain securities dealers and eligible traders who have made valid elections. Whether a particular perpetual qualifies as a security or related derivative for those purposes must be determined under the applicable statutory definitions.

A valid Section 475(f) election can materially affect the timing and character of gains and losses on positions within the covered trading business. Election procedures, taxpayer identity, the applicable tax year, and identification of excluded investment positions may all be relevant.

Trader status and dealer status remain separate questions. A proprietary trading firm can operate an active trading business without necessarily being a dealer for federal tax purposes. High frequency execution, automated market making, substantial volume, and liquidity provision are facts to evaluate rather than statutory substitutes for the required classification.

Related positions introduce additional considerations. A trading firm may hold an equity perpetual alongside the underlying shares, listed options, conventional equity futures, or offsetting derivatives at another venue.

Section 1092 can affect the recognition of losses where positions form a qualifying straddle. Section 1259 may apply to certain constructive sales of appreciated financial positions, while tax hedging identification requirements and other provisions can affect character and matching.

These rules require analysis of the entire relevant position structure rather than each venue's reported profit in isolation.

The accounting must also be capable of substantiating that analysis.

Professional firms may generate substantial execution volume while carrying relatively modest net exposure. Individual trades can establish new positions, reduce existing exposure, or reverse direction. Funding, variation settlement, execution fees, rebates, dividend adjustments, and collateral transfers may appear as separate entries across different venue records.

A financial reporting process needs to distinguish those economic events and reconcile them to cash balances and open positions. Depending on the entity and reporting framework, the process may require position level records beneath the general ledger, formal period end reconciliations, and support for the valuation of outstanding contracts.

The tax workpapers then apply the relevant recognition and character rules to the substantiated transaction record. That process must account for prior marks, actual position terminations, separately classified payments, relevant elections, and any applicable related position limitations.

For equity perpetuals, corporate actions make historical contract terms particularly important. Stock splits can change the relationship between a contract's quantity and its underlying exposure, while mergers, reorganizations, delistings, and other events may result in adjustments or contractual termination.

A trader preparing 2026 returns should preserve execution and position records, the applicable contract specifications, historical multipliers, funding transactions, corporate action notices, clearing and margin records, fees, and year end open positions. The original records should be retained even where the platform provides consolidated monthly or annual summaries.

Those records support the bridge from venue activity to accounting balances and ultimately to the tax treatment adopted for the return.

Our professional trader tax and accounting practice addresses these matters for active traders and professional trading operations. The same issues can become more extensive for trading firms and market makers operating multiple strategies, accounts, or venues.

How Camuso CPA Approaches Perpetual Futures Tax Reporting

Camuso CPA works with professional traders, market makers, and trading firms whose activity requires specialized derivatives tax analysis and transaction level accounting.

For single stock perpetuals, the work begins with identifying the actual instrument and governing contractual terms. The applicable securities futures or alternative derivative classification determines which statutory provisions must be evaluated, including Sections 1234B, 1256, 475, and potentially 871(m).

Where material activity spans multiple venues or includes related positions, the analysis also requires reconciliation of executions, settlements, funding, collateral, and period end positions before the amounts can be incorporated into tax reporting.

Our perpetual contract accounting services address the underlying records and financial reporting requirements, while our perpetual contract tax services focus on the applicable tax character, recognition, and reporting considerations.

The Tax Treatment Will Depend on the Instrument and Taxpayer

Single stock perpetual futures are entering the U.S. market under a regulatory classification that remains subject to judicial challenge. The ultimate treatment of a particular instrument will depend on its legal status and the statutory provisions that apply to that classification.

For a qualifying securities futures contract, Congress has already supplied substantial guidance. Section 1256 generally excludes ordinary securities futures from its 60/40 treatment, while Section 1234B establishes specific gain and loss character rules.

The newly introduced perpetual structure creates additional questions concerning interim funding, dividend adjustments, recognition of variation settlements, and withholding. Those questions require attention to the actual contracts and transactions rather than a uniform classification based on the product name.

The reporting consequences are especially important for professional traders operating across multiple instruments and venues. Accurate tax reporting depends on identifying each relevant economic event, preserving its supporting records, and applying the statutory treatment appropriate to the contract and taxpayer.

Frequently Asked Questions

Are Kalshi single stock perpetual futures eligible for Section 1256 treatment?

If the contracts qualify as securities futures contracts, Section 1256(b)(2)(A) generally excludes them from standard 60/40 treatment unless the dealer securities futures exception applies. The regulatory classification is currently being challenged in federal court. The applicable tax analysis must account for the instrument's legal status and any relevant exceptions.

How does Section 1234B apply to single stock perpetual futures?

Section 1234B generally determines the character of gain or loss from the sale, exchange, or termination of a qualifying securities futures contract by reference to the underlying property. For an investor whose referenced stock would be a capital asset, capital treatment may apply, subject to the statute's exceptions and special rules for short positions and related transactions.

Are funding payments on equity perpetuals ordinary income?

There is no published IRS rule establishing ordinary treatment for all equity perpetual funding payments. The analysis depends on the governing contract, the nature of the payment, the applicable tax regime, and the taxpayer's circumstances. Separately reported funding does not independently establish ordinary character or deductibility.

Are dividend adjustments on single stock perpetual futures taxable as dividends?

A contractual adjustment received by a perpetual holder is not automatically an actual dividend received through stock ownership. Its domestic income tax treatment depends on the governing instrument and applicable character rules. Separately, certain payments to non-U.S. recipients may be subject to the dividend equivalent withholding rules under Section 871(m).

Does Section 871(m) apply to Kalshi equity perpetuals?

It may apply where a transaction satisfies the regulatory requirements for a dividend equivalent payment involving U.S. securities. The analysis requires the actual contract terms, relevant delta determination, applicable testing rules, and recipient status. IRS Notice 2026-61 extends important transitional provisions through 2028 without eliminating withholding obligations for covered transactions.

Will Kalshi or Coinbase issue Form 1099-B for equity perpetuals?

Qualifying securities futures contracts are addressed under Treasury Regulation Section 1.6045-1, including rules for specified securities, covered securities, and closing transactions. The specific reporting obligations of Kalshi related intermediaries or Coinbase depend on the instrument, broker, transaction, and applicable exclusions. The existence of the regulation does not establish that every equity perpetual customer will receive an identical Form 1099-B.

Can professional traders elect Section 475 treatment for equity perpetual futures?

Section 475 treatment may be available where the taxpayer qualifies, the instrument satisfies the relevant statutory definition, and an effective election and method apply. Professional trading activity alone does not establish eligibility or a valid election. The treatment of covered positions must be evaluated together with the taxpayer's other trading activities and applicable statutory coordination rules.
