Can futures losses offset stock gains?
Learn when a U.S. futures loss can enter the capital-gain calculation, how Section 1256 and year-end mark-to-market work, and which records to reconcile
Direct answer
A loss from a qualifying U.S. Section 1256 futures contract generally enters the capital-gain and loss calculation and can reduce capital gains, including stock gains, after the applicable netting and reporting steps. That does not mean every futures loss is an immediate ordinary-income deduction or that every product receives Section 1256 treatment. Contract classification, year-end mark-to-market, hedging and straddle rules, and the taxpayer's complete return all matter
Confirm what kind of futures contract you own
Start with the contract classification, not the word “futures” in a platform label. Many exchange-traded futures are regulated futures contracts under Section 1256, but foreign products, securities futures, dealer positions, hedges, mixed straddles, and other arrangements can have different rules. The broker's tax statement is a useful starting point, not a substitute for checking the contract and the current IRS instructions.
For a qualifying Section 1256 contract, capital gains and losses are generally split 60% long-term and 40% short-term regardless of the actual holding period. That is a character rule, not a 60% tax rate or a promise that a loss will offset a particular stock lot. How futures are taxed under Section 1256 explains the broader classification.
Keep the exact symbol, exchange, contract month, multiplier, account type, opening and closing dates, and broker tax category. A continuous chart or a strategy name does not establish the tax product.
Understand why an open futures loss can be recognized at year-end
Section 1256 contracts held at the end of the tax year are generally treated as sold at fair market value on the last business day for tax purposes. An open position can therefore create a tax gain or loss even though the trading position remains open.
Suppose a qualifying contract has a $4,000 year-end mark-to-market loss and the same taxpayer has a $9,000 realized stock gain. Before other items and adjustments, the combined capital result is a $5,000 gain. If the futures loss is $12,000, the simplified combined result is a $3,000 capital loss. The example does not determine tax owed; the 60/40 character, other transactions, carryovers, filing facts, and current instructions still apply.
The year-end tax mark is separate from the daily cash and economic settlement process. Do not use deposits, withdrawals, or a broker's intraday P&L screen as the tax basis. Futures realized versus unrealized P&L covers the account-record distinction.
Report the result before combining it with stock transactions
Form 6781 is generally used for Section 1256 contracts that were closed during the year or marked at year-end. The form applies the relevant short-term and long-term split before the result flows into the broader capital-gain reporting process.
Stock sales may be reported through Form 8949 and Schedule D under the current instructions. Keep the futures calculation and the stock calculation identifiable until the forms call for the amounts to be combined. A single account total can hide a missing year-end mark, a duplicated broker amount, or a contract that was not Section 1256.
Reconcile the broker's Form 1099-B, the year-end open-position report, trade confirmations, and Form 6781 rather than rebuilding the result from cash movements. The broker may aggregate futures activity or use a product code that requires a separate review.
Check exceptions before treating the loss as available
Hedging and straddle rules
A futures position that hedges a stock, business asset, or another investment can trigger special timing or character rules. Offset positions can also create a tax straddle, which may defer losses or change the treatment of gains. Economic offset matters even when the trades have different symbols and settle in different ways.
Write down the position that the futures contract was intended to offset, the dates of both legs, and any election or hedge documentation. Do not assume that the standard 60/40 result survives every hedging fact.
Wash-sale assumptions do not solve futures tax questions
The stock wash-sale rule and the Section 1256 rules address different questions. A stock loss followed by a replacement security needs its own analysis, while a futures position may be part of a straddle or hedge. Do not label every replacement or roll as a wash sale, and do not use the absence of a broker flag as proof that a loss is currently available.
Nonqualifying products
Options on futures, security futures, foreign contracts, and products with special settlement or dealer status can differ from a regulated futures contract. Confirm the exact instrument before copying a result from a standard U.S. exchange-traded future.
Use a year-end reconciliation workflow
1. List every open and closed futures contract by exact symbol and month 2. Confirm the broker's tax classification and whether Section 1256 applies 3. Calculate realized P&L and the year-end mark separately 4. Record any stock, business, or option position that the futures trade hedged 5. Identify straddle, hedge, dealer, foreign, or other exception facts 6. Preserve the 60/40 character until the applicable form combines it 7. Reconcile 1099-B, confirmations, open-position statements, Form 6781, Form 8949, and Schedule D 8. Ask a qualified tax professional to review uncertain classifications or cross-account positions

Common questions
Can a Section 1256 futures loss reduce a stock gain?
Generally, a properly recognized capital loss from a qualifying Section 1256 contract can enter the capital-gain and loss calculation and reduce a stock gain. The 60/40 character, other transactions, carryovers, and any hedge or straddle rule still affect the final return.
Does an open futures loss count at December 31?
For a qualifying Section 1256 contract, the year-end mark-to-market rule generally treats the open position as sold at fair market value on the last business day. Verify the product and the current tax-year instructions before applying that rule.
Is every futures loss split 60/40?
No. The 60/40 split generally applies to capital gain or loss from qualifying Section 1256 contracts. Foreign contracts, security futures, hedges, straddles, dealer positions, and other products can differ.
Can I use the broker's cash statement as the futures tax loss?
No. Margin deposits and withdrawals are account cash movements, not automatically tax basis or gain. Reconcile trade records, the year-end mark, broker tax forms, and Form 6781 instead.
What if the futures position hedged my stocks?
Document both positions and review the applicable hedging and straddle rules. An intended hedge can change timing or character, so do not assume the standard Section 1256 result applies without checking the facts.
