Do Forex Traders Pay Tax in the USA: Section 988 and 1256 Rules

Yes. Forex traders in the USA do pay tax on their profits, and the federal top marginal rate reaches 37% for 2026. The IRS runs currency trading through two very different regimes: Section 988 treats gains and losses as ordinary income, while Section 1256 applies the 60/40 rule, blending long-term and short-term capital rates to a maximum of roughly 26.8% at the top bracket. Which one governs your trades depends on the contract type and whether you make a specific election, and the gap between them can move thousands of dollars a year.

Section 988 Is the Default for Spot Forex

If you trade spot currency pairs through a typical retail forex broker, your gains and losses fall under Internal Revenue Code Section 988 automatically. Section 988 classifies foreign currency transaction gains and losses as ordinary.¹ Net profits stack on top of wages and other income, then get taxed at your regular marginal rate, up to 37% on taxable income above $640,600 for single filers in 2026.²

The upside is on the loss side. Ordinary losses under Section 988 are not capped at the $3,000 annual limit that restricts capital losses from stocks.³ Lose $30,000 trading spot forex under Section 988, and the full amount offsets your other ordinary income the same year. For traders who take large drawdowns, that unlimited offset is a real advantage over capital treatment.

Section 1256 and the 60/40 Rule

The friendlier tax treatment lives under Section 1256, which covers regulated futures contracts, foreign currency contracts traded on qualified exchanges, and certain listed options. Qualifying contracts get the 60/40 split: 60% of your net gain or loss is treated as long-term capital gain or loss, and 40% as short-term, no matter how briefly you held the position.⁴

The math is the point. Long-term capital gains top out at 20%; short-term gains run up to 37%. For a top-bracket trader, the blended maximum under 60/40 works out to about 26.8% (60% × 20% + 40% × 37%), compared with a flat 37% under Section 988. In the 24% bracket, the blended rate is roughly 18.6%. On a large account, that gap compounds fast.

Section 1256 also carries a loss carryback that ordinary losses don’t get. A net Section 1256 contract loss can be carried back to offset Section 1256 gains in the three prior tax years by election.⁵ The carryback offsets only prior Section 1256 gains and cannot create a net operating loss in the carryback year, but it lets you recover tax paid in profitable years when a bad one arrives. Section 1256 contracts are also exempt from wash sale rules,⁶ so you can close a losing position and reopen a similar one without forfeiting the deduction.

Which Contracts Actually Qualify

This is where most retail traders get stopped. Section 1256 treatment applies to regulated futures contracts and foreign currency contracts traded on qualified board of trade exchanges.⁴ Currency futures on the CME qualify. The over-the-counter spot forex contracts sold by most retail brokers do not, and they default back to Section 988 ordinary income treatment.

To get the favorable rate, you either trade currency futures on a regulated exchange or make an election to opt out of Section 988 on your spot trades. The election doesn’t hand you the 60/40 split, but it converts ordinary treatment to capital treatment, which comes with its own set of trade-offs.

Electing Out of Section 988

The Internal Revenue Code lets traders elect capital gain or loss treatment on certain forward contracts and similar instruments that would otherwise sit under Section 988. The catch is that the election is per-transaction: each trade must be identified as a capital asset before the close of the day it is entered.¹ You cannot wait until December and label your winners capital while keeping the losers as ordinary deductions.

Most traders satisfy this by keeping a contemporaneous log identifying every trade as capital from the moment it opens. Some brokers allow an account-level note, but the documentation burden sits with you.

Once trades are capital rather than ordinary, short-term capital gains (held one year or less, which covers almost all retail forex activity) still get taxed at ordinary rates. The real difference shows up when you lose: capital losses are capped at $3,000 per year against ordinary income once they exceed capital gains,³ and wash sale rules apply. Electing out generally suits traders who are consistently profitable and want to pair forex gains with capital losses from other investments. Traders with frequent losing streaks usually do better staying under Section 988 for the unlimited ordinary loss deduction.

The 3.8% Net Investment Income Tax

High-income traders owe an additional 3.8% Net Investment Income Tax on top of regular income tax. NIIT applies to the lesser of your net investment income or the amount by which your modified adjusted gross income exceeds these thresholds:⁷

Single or head of household: $200,000
Married filing jointly: $250,000
Married filing separately: $125,000

Net investment income includes income from trading financial instruments and commodities.⁸ The thresholds are not indexed to inflation, so they catch more taxpayers each year. For a top-bracket trader under 60/40, the effective maximum climbs from 26.8% to about 30.6% with NIIT. Under Section 988, it pushes the top effective rate from 37% to 40.8%.

How to Report Forex Income

The forms you file follow the regime.

Section 1256 Contracts: Form 6781

Qualifying Section 1256 contracts go on Form 6781, Gains and Losses From Section 1256 Contracts and Straddles.⁹ The form uses mark-to-market accounting: open positions are treated as sold at fair market value on the last business day of the tax year. Total annual gain or loss is split automatically, 40% to Schedule D as short-term and 60% as long-term.¹⁰

Section 988 Transactions: Schedule 1 or Form 4797

Spot forex under Section 988 that does not rise to a trade or business goes on Schedule 1 (Additional Income and Adjustments to Income), which feeds into Form 1040. If your trading qualifies as a trade or business, you may report ordinary gain or loss on Form 4797, Sales of Business Property, which applies to traders who have made a mark-to-market election.¹¹ Trade-or-business status also opens the door to Schedule C for trading expenses.

Under either regime, track cost basis and closing value on every trade. Commissions and spreads reduce net gain or add to net loss. Your broker will send year-end statements, but the IRS expects you to reconcile them against your own records.

Quarterly Estimated Tax Payments

Forex brokers don’t withhold income tax the way an employer does. If you expect to owe $1,000 or more after withholding and credits, you owe quarterly estimated tax to avoid an underpayment penalty.¹² The 2026 deadlines:

April 15, 2026, for income earned January through March
June 15, 2026, for income earned April through May
September 15, 2026, for income earned June through August
January 15, 2027, for income earned September through December

You avoid the penalty by paying at least 90% of the current year’s tax or 100% of last year’s (110% if your prior-year AGI exceeded $150,000). For traders with volatile income, the prior-year safe harbor is the simpler path because it doesn’t require you to guess this year’s profits. The IRS charges interest on underpayments at a rate that resets quarterly; for the first half of 2026 it runs 6% to 7%.¹³

Trader Tax Status and Section 475(f)

Traders who run forex as a full-time business may qualify for Trader Tax Status. The IRS evaluates TTS on several factors:¹⁴

Profit motive from daily price movements rather than long-term appreciation
Substantial trade frequency and dollar volume
Continuity and regularity of activity throughout the year

Holding periods, time devoted to trading, and whether trading supports your livelihood also factor in. Calling yourself a trader is not enough. If the activity falls short, the IRS treats you as an investor regardless of the label.¹⁴

Traders with TTS can make a Section 475(f) mark-to-market election. This converts all trading gains and losses to ordinary income and loss. Ordinary losses under Section 475 are fully deductible against any type of income with no annual cap, and wash sale rules stop applying. The trade-off: you give up 60/40 on any Section 1256 contracts and lock all gains into ordinary rates. The election is prospective. For it to take effect in 2026, the election statement had to be filed with your 2025 return or extension by April 15, 2026, followed by Form 3115 with the 2026 return.

One helpful note: trading income generally doesn’t trigger the 15.3% self-employment tax, because trading profits are not earnings from services. That holds true for TTS traders filing Schedule C.

Foreign Broker Reporting: FBAR and FATCA

If you trade through a broker based outside the United States, you may have reporting obligations that are separate from how the profits are taxed. Penalties for missing these are steep, so they matter even at modest balances.

FBAR (FinCEN Form 114)

File the Report of Foreign Bank and Financial Accounts if the combined value of all your foreign financial accounts exceeded $10,000 at any point during the calendar year.¹⁵ The FBAR goes through FinCEN’s BSA E-Filing System, not with your tax return.¹⁶ The deadline is April 15 following the calendar year, with an automatic extension to October 15 that requires no separate request. The obligation applies whether or not the account produced any income, and non-willful penalties can reach $10,000 per violation.

FATCA (Form 8938)

FATCA requires a separate disclosure of specified foreign financial assets on Form 8938, filed with your annual tax return. Thresholds depend on filing status and residency:¹⁷

Single, living in the U.S.: total value exceeds $50,000 on the last day of the year or $75,000 at any point in the year
Married filing jointly, living in the U.S.: total value exceeds $100,000 on the last day of the year or $150,000 at any point in the year

Higher thresholds apply to taxpayers living abroad. Form 8938 and the FBAR overlap but are separate requirements with different thresholds and different filing systems. Filing one does not cover the other.

Records to Keep

Whichever regime applies, the IRS expects detailed records. At minimum, log the open and close date, currency pair, position size, entry and exit prices, and any commissions or fees. Section 1256 contracts also need the fair market value of open positions on the last business day of the tax year for the mark-to-market calculation.

If you have elected out of Section 988, your records need to document that each trade was identified as a capital asset before the close of the day it was entered. A contemporaneous trading journal or time-stamped broker confirmation is the cleanest way to meet that standard. Traders claiming TTS should also keep documentation of the frequency, regularity, and time commitment behind their trading, since those are the factors the IRS weighs.¹⁴
