Do I Pay Tax on Forex Trading in the US?

By Ken Chigbo, Founder, KenMacro. Published 2026-05-13.

Forex profits earned by US residents are taxable, and the rules are more nuanced than they look from the outside. The desk gets this question constantly from retail traders who assume forex is taxed like equities. It is not. The US tax code carves out specific treatment for currency transactions, and the regime a trader falls under depends on the instrument traded and whether a formal written election was made before any profits were realised.

By default, spot forex traded through a retail broker falls under Section 988 of the Internal Revenue Code. Section 988 treats foreign currency gains and losses as ordinary income, taxed at the trader’s marginal income tax rate. That can be as high as 37 per cent at the federal level for top earners. The upside of Section 988 is that losses are fully deductible against ordinary income without the 3,000 dollar capital loss cap that applies to equity traders.

Section 1256 is the alternative regime. It applies automatically to regulated futures contracts, including currency futures traded on the CME. Under Section 1256, gains and losses are split 60 per cent long-term capital gain and 40 per cent short-term capital gain, regardless of how long the position was actually held. The blended top federal rate works out around 26.8 per cent, materially lower than the ordinary income ceiling.

Spot forex traders can opt into Section 1256 treatment, but only by making a formal written election. The election must be made internally, contemporaneously, before any of the gains being elected on are recognised. There is no IRS form filed at the time of election; the trader retains the written record and applies the treatment when filing. Many traders miss this step and lose the ability to claim 1256 treatment for the year.

Which regime is better depends on the trader’s overall situation. Profitable traders in high marginal brackets usually prefer Section 1256 because the 60/40 split lowers the effective rate. Loss-making traders, or traders with low overall income, often prefer Section 988 because ordinary losses offset other ordinary income without the capital loss limitation. The desk has seen profitable years and loss years swing the optimal answer in either direction.

State tax is the layer most retail traders forget. Federal treatment is only half the picture. California, New York, New Jersey, and several other high-tax states add another 5 to 13 per cent on top of federal rates, and state rules on capital versus ordinary treatment do not always mirror federal rules. A trader resident in Florida or Texas escapes state income tax entirely, which is one reason a meaningful number of full-time traders relocate.

Reporting mechanics matter. Section 988 gains and losses flow onto the trader’s return as ordinary income, typically reported as a single net figure with supporting documentation retained. Section 1256 contracts are reported on Form 6781, which calculates the 60/40 split and feeds the amounts into Schedule D and Form 8949. Brokers issue 1099-B forms summarising activity, but the trader is responsible for ensuring the elections and treatment align.

Trader tax status is a separate consideration. A trader who qualifies as a Trader in Securities under IRS standards (substantial activity, regular and continuous trading, intent to profit from short-term price moves) can elect mark-to-market accounting under Section 475(f). That election converts trading gains and losses to ordinary treatment and removes the wash sale rule, but it locks the trader into the regime and has meaningful operational consequences.

Record-keeping is non-negotiable. The desk advises every trader, whether trading a 500 dollar account or a seven-figure account, to retain monthly broker statements, the written Section 1256 election if made, and a running ledger of realised gains and losses by trade. The IRS can request documentation years after filing, and reconstructing forex activity from a broker that has since closed or migrated platforms is painful.

None of the above constitutes tax advice. The desk publishes this as general background for traders navigating the US forex tax landscape. Tax law changes, individual circumstances vary, and the interaction between forex trading, other income sources, retirement accounts, and entity structures is genuinely complex. Anyone trading forex at scale in the US should engage a qualified CPA or tax attorney who specialises in trader taxation before filing season.

The election deadline is the trap

The Section 1256 opt-in for spot forex must be documented in writing before the gains being elected on are realised. Traders who decide in April that they want 1256 treatment for last year cannot retroactively elect. The desk has seen this mistake cost five-figure tax bills. If a trader anticipates a profitable year and wants 1256 treatment, the written election should sit in a dated file before the first trade of the year.

State residency drives the after-tax outcome

Federal rates are uniform, but state tax exposure varies from zero in Florida, Texas, Nevada, and a handful of others to over 13 per cent in California. For a trader netting six figures from forex, state residency can shift after-tax income by 20,000 dollars or more annually. Some traders relocate specifically for this reason. The desk treats state planning as part of any serious tax conversation.

Entity structures add complexity

Traders sometimes trade through LLCs, S-corps, or family limited partnerships to access health insurance deductions, retirement contributions, or income splitting. These structures can be useful but introduce filing complexity, state-level franchise taxes, and substance requirements the IRS examines closely. The desk does not recommend entity formation for accounts under six figures; the administrative cost typically outweighs the tax benefit at that scale.

Frequently asked

Is forex trading taxed as capital gains in the US?

Not by default. Spot forex falls under Section 988 and is taxed as ordinary income at marginal rates. Currency futures on regulated exchanges fall under Section 1256 with 60/40 capital gains treatment. Spot forex traders can elect 1256 treatment in writing before realising the gains.

What is the Section 1256 election for forex?

Section 1256 election allows spot forex traders to opt out of ordinary income treatment and instead receive 60 per cent long-term and 40 per cent short-term capital gains treatment. The election must be documented in writing, contemporaneously, before any gains in the tax year are realised. No IRS form is filed at election time.

Do I report forex profits on Form 8949 or Form 6781?

Section 1256 contracts and elected 1256 forex are reported on Form 6781, which calculates the 60/40 split and feeds into Schedule D. Section 988 ordinary income is reported on the trader’s return as ordinary income. Form 8949 is generally used for securities, not forex specifically.

Are forex losses tax deductible in the US?

Yes. Under Section 988, forex losses are fully deductible against ordinary income with no 3,000 dollar annual cap. Under Section 1256, losses are treated as 60/40 capital losses and subject to capital loss limitations, though a three-year carryback election is available to offset prior 1256 gains.

Do I pay state tax on forex trading profits?

Yes, in states with income tax. California, New York, and New Jersey impose additional rates of 5 to 13 per cent on top of federal. Florida, Texas, Nevada, Tennessee, Washington, Wyoming, and South Dakota do not levy state income tax on individual trading profits.

Can I avoid US tax on forex by using an offshore broker?

No. US residents are taxed on worldwide income regardless of where the broker is domiciled. Using an offshore broker does not eliminate US tax liability and may add FBAR and FATCA reporting requirements. Concealing offshore accounts carries severe civil and criminal penalties under US law.

Should I get a CPA for my forex trading taxes?

For anything beyond modest hobby-level activity, yes. Trader taxation involves Section 988, Section 1256, the 475(f) mark-to-market election, trader tax status, and entity considerations. The KenMacro desk recommends engaging a CPA who specifically advertises trader tax expertise rather than a general practitioner unfamiliar with the elections.
