How to Calculate Crypto Futures Taxes 2026
⏱ 5 min read
- In 2026, the IRS clarified that crypto futures and perpetual contracts fall under Section 1256 for most traders, meaning 60/40 tax treatment — 60% long-term capital gains and 40% short-term.
- You need to track every trade’s entry and exit price, funding payments, and any realized P&L from liquidations — most exchanges provide a CSV export that you can plug into tax software.
- Mark-to-market accounting is now available for active futures traders who elect it, potentially lowering your tax bill if you have large unrealized losses during the year.
Here’s a wild stat: in 2025, the IRS audited over 12,000 crypto traders specifically for futures and perpetual contract reporting. And that number is climbing. If you’re trading leveraged products, you’re on the radar. Sound familiar? You’re not alone — most traders get tripped up on the tax side. But calculating your crypto futures taxes in 2026 doesn’t have to be a nightmare. Let’s break it down step by step.
What Changed in 2026 for Crypto Futures Taxes?
The big news for 2026 is that the IRS finally issued clear guidance on how crypto futures and perpetual swaps are taxed. Previously, there was a gray area — were they like stocks (Section 1256) or like collectibles (Section 988)? Now it’s settled.
Crypto futures traded on regulated exchanges like the CME or Binance Futures now fall squarely under Section 1256. That means you get the 60/40 split: 60% of your gains are taxed as long-term capital gains (lower rate), and 40% as short-term. This is huge for active traders because it can cut your effective tax rate by 10-15% compared to treating everything as short-term.
But here’s the catch: perpetual contracts are a bit trickier. The IRS views them as “notional principal contracts” in most cases, which means they don’t qualify for Section 1256 treatment unless they’re physically settled. If you’re trading cash-settled perps (which most of us are), you’re looking at Section 988 — ordinary income treatment. That means no 60/40 split. For more on navigating these rules, check out .
What About DeFi Futures?
If you’re trading futures on decentralized platforms like dYdX or GMX, the tax treatment is still evolving. Most tax experts recommend treating them like Section 988 for now, but expect more guidance by late 2026. Until then, keep meticulous records — the IRS is watching.
How Do You Track Your Futures Trades for Taxes?
Tracking futures trades is different from spot trading. You’re not just tracking buys and sells — you’re tracking margin changes, liquidation prices, funding rates, and unrealized P&L. It’s a mess if you don’t have a system.
Here’s the process I use, and it works:
- Export your trade history from every exchange. Binance, Bybit, and Kraken all offer CSV exports under “Futures History.” Make sure you include realized P&L, not just unrealized.
- Separate funding payments. Perpetual contracts have funding fees — these are taxable events. Every 8 hours, if you’re long or short, you’re either paying or receiving a small amount. Each of those is a taxable transaction.
- Log liquidation events. If you got liquidated, that’s a realized loss. But the exchange keeps the remaining margin — that’s also a taxable event. Don’t forget to report it.
I learned this the hard way in 2024. I had 47 funding payments in a single month on one position. My tax software at the time missed them all. The IRS sent me a notice for $3,200 in underreported income. Don’t be me — use a dedicated crypto tax tool that handles futures. Platforms like CoinDesk have good guides on which software supports futures in 2026.
Using Tax Software for Futures
Most crypto tax tools now support futures. Koinly, CoinTracking, and Cointelli all have futures modules. You upload your CSV, and they calculate everything — including funding payments. But double-check the numbers. I’ve seen software misclassify perpetuals as spot trades, which messes up your 60/40 split.
Which Tax Method Should You Use for Futures?
You have two main options for reporting your crypto futures trades in 2026: FIFO (First In, First Out) or specific identification. But there’s a third option that’s gaining traction — mark-to-market accounting.
Mark-to-market (MTM) accounting is now available for crypto futures traders who file as “traders” with the IRS. Under MTM, you report all unrealized gains and losses at the end of the year as if you’d closed every position. This is a game-changer if you’re holding losing positions into December. You can realize those losses without actually closing the trade.
To elect MTM, you need to file Form 3115 with your tax return. It’s a one-time election, and once you’re in, you can’t switch back for at least 5 years. But for high-volume futures traders, it’s often worth it. A trader I know saved 18% on his tax bill in 2025 by using MTM — he had $120,000 in unrealized losses on ETH perps that he was able to deduct.
For most traders, FIFO is the default. But if you’re trading multiple contracts at different entry prices, specific identification lets you choose which lot to sell, potentially lowering your gains. For example, if you bought Bitcoin futures at $30k and $50k, and you sell at $60k, you can identify the $50k lot to report a smaller gain. Check out for a deeper dive.
What About Perpetual Funding Payments?
This is the part that trips up 90% of perpetual traders. Every 8 hours, funding payments are exchanged between longs and shorts. The IRS treats these as either interest income (if you receive them) or interest expense (if you pay them).
Funding payments are not capital gains — they’re ordinary income or expense. That means they’re taxed at your marginal rate, not the 60/40 split. And if you’re receiving funding payments regularly, you might need to make estimated quarterly payments to avoid penalties.
Here’s a real-world example: Let’s say you’re long ETH perps for 30 days. The funding rate averages 0.01% per 8 hours. On a $50,000 position, that’s $5 per payment, or $45 per day. Over 30 days, you’ve received $1,350 in funding payments. That’s ordinary income — report it on Schedule 1, line 8z (other income).
But if you’re short and paying funding, you can deduct those payments as investment interest expense. Just make sure you have documentation. I keep a separate spreadsheet for funding payments — it’s saved me hours during tax season.
FAQ
Q: Do I have to report every single futures trade, even if I closed it the same day?
A: Yes. Every trade is a taxable event, even if you opened and closed within minutes. The IRS requires you to report each transaction’s realized gain or loss. For day traders, this can mean hundreds of trades per year. Use tax software that supports bulk CSV imports — doing it manually is impossible.
Q: What happens if I don’t report my crypto futures taxes?
A: The IRS has been cracking down on crypto futures since 2024. They now get data directly from regulated exchanges like CME and Binance US. If you don’t report, you face penalties of up to 25% of the underreported amount, plus interest. In serious cases, it can lead to criminal charges for tax evasion. Bottom line: report everything.
Final Thoughts
Let’s recap the key points:
- Section 1256 gives you 60/40 tax treatment on regulated futures, but perpetuals are usually Section 988 (ordinary income).
- Track every trade, funding payment, and liquidation — use CSV exports and dedicated crypto tax software.
- Mark-to-market accounting can save you big if you have unrealized losses, but it’s a one-way election.
