Yes, forex trading is taxable in the United States. Every dollar of profit you make trading currencies is subject to federal income tax, though the specific rate depends on how your trades are classified. Most retail forex traders fall under one of two tax frameworks: Section 988, which taxes gains as ordinary income, or Section 1256, which offers a more favorable blended rate. Understanding which applies to you can make a meaningful difference in what you owe.
The Default: Section 988 and Ordinary Income
By default, the IRS treats forex gains and losses as ordinary income under Section 988 of the Internal Revenue Code. This means your profits are taxed at the same rate as your wages, salary, or freelance income, using your marginal tax bracket. If you’re in the 24% bracket, your forex gains are taxed at 24%. If you’re in the 37% bracket, that rate applies to your trading profits too.
Section 988 covers what the IRS calls “nonfunctional currency transactions.” For most retail traders buying and selling currency pairs through a broker, this is the category you land in automatically. You don’t need to file any special election or notify the IRS to use this treatment. It simply applies unless you take steps to choose something different.
One upside of Section 988: there’s no cap on how much loss you can deduct against your other ordinary income. If you lose $15,000 trading forex and earned $80,000 at your job, you can offset that trading loss against your wages, reducing your taxable income to $65,000. That’s more generous than the standard capital loss rules, which limit deductions to $3,000 per year against ordinary income.
The Alternative: Section 1256 and the 60/40 Split
Some forex contracts qualify for a different tax treatment under Section 1256, which splits your gains into two buckets: 60% is taxed as long-term capital gains and 40% as short-term capital gains. This applies regardless of how long you actually held the position. Even a trade you opened and closed in five minutes gets this blended treatment.
The practical benefit is a lower effective tax rate. Long-term capital gains are taxed at 0%, 15%, or 20% depending on your income, while short-term gains are taxed at your ordinary rate. For someone in the 37% bracket, the 60/40 split drops the blended rate to roughly 26.8%, saving more than 10 percentage points compared to pure ordinary income treatment.
Section 1256 treatment applies specifically to regulated futures contracts and certain foreign currency contracts traded on regulated exchanges. Spot forex trades through most retail brokers typically fall under Section 988 by default, not Section 1256. However, traders dealing in forex futures or certain interbank forward contracts may qualify. The distinction depends on the type of contract and where it’s traded, not simply on the fact that currencies are involved.
Opting Out of Section 988
If your forex contracts could qualify under Section 1256, you may need to elect out of Section 988 treatment to claim the 60/40 split. This election should be made internally (documented in your own records) before you begin trading for the year. The IRS requires that you make this choice prospectively, not retroactively after seeing whether you had gains or losses. Keep a written record of the date you made the election and the reasoning, in case the IRS questions your filing.
Choosing between the two involves a tradeoff. Section 1256 gives you lower tax rates on gains, but Section 988 gives you unlimited ordinary loss deductions. If you expect to be profitable, the 60/40 split usually saves money. If you anticipate losses, especially large ones, staying under Section 988 lets you write off more against your other income.
How to Report Forex Gains and Losses
Your reporting method depends on which tax section applies to your trades.
- Section 1256 contracts: Report gains and losses on Form 6781 (Gains and Losses From Section 1256 Contracts and Straddles). The form calculates the 60/40 split for you. The resulting figures then flow to Schedule D of your tax return.
- Section 988 transactions: There is no dedicated IRS form for Section 988 forex gains. Most traders report these on Schedule 1 as “other income” or on Schedule C if they’re operating as a business. Your broker may or may not issue a 1099-B, so you’ll likely need to track your own trades and calculate your net gain or loss for the year.
Keep detailed records of every trade: the date opened, date closed, the currency pair, your cost basis, and the proceeds. Most trading platforms let you export a transaction history, which simplifies this at tax time. If you traded through multiple brokers, you’ll need to consolidate all of them.
Mark-to-Market Rules Under Section 1256
Section 1256 contracts follow mark-to-market rules, meaning all open positions are treated as if they were sold at fair market value on the last business day of the tax year. Even if you haven’t closed a trade, you owe tax on any unrealized gains as of December 31. Conversely, unrealized losses count as deductions for that year.
This also unlocks a useful feature: loss carrybacks. If you have a net Section 1256 loss, you can carry it back up to three prior tax years and apply it against Section 1256 gains from those years. You file an amended return to claim the refund. This option doesn’t exist under Section 988 or standard capital loss rules.
Capital Loss Limits for Section 1256
While Section 988 losses can offset ordinary income without a cap, Section 1256 losses follow capital loss rules. If your Section 1256 losses exceed your capital gains for the year, you can only deduct up to $3,000 of the excess against ordinary income ($1,500 if married filing separately). Any remaining losses carry forward to future tax years. This is worth considering if you’re weighing which tax treatment to elect.
What About Cryptocurrency and Digital Currency Pairs
If you’re trading crypto pairs on a forex-style platform, those transactions are not treated as forex for tax purposes. The IRS classifies cryptocurrency as property, not currency, so different rules apply. Gains and losses on crypto trades are reported as capital gains, typically on Form 8949 and Schedule D. Don’t mix crypto reporting with your forex reporting, even if both happen on the same platform.
Keeping Your Tax Bill Manageable
Active forex traders can reduce their tax burden with a few straightforward strategies. First, choose the right tax section before the year begins. If your historical pattern shows consistent profitability, the Section 1256 election usually results in a lower bill. If you’re still learning and expect losses, Section 988’s unlimited ordinary loss deduction is more valuable.
Second, set aside money for taxes as you trade. Unlike wage income, forex profits don’t have taxes automatically withheld. If you expect to owe more than $1,000 in tax for the year, the IRS requires quarterly estimated payments (due in April, June, September, and January) to avoid underpayment penalties.
Third, maintain clean records throughout the year rather than scrambling in April. A simple spreadsheet tracking each trade’s date, pair, size, entry price, exit price, and net result will save hours of work and reduce the risk of reporting errors.
