Popular questions
How do cryptocurrency taxes work?
The IRS treats crypto as property. When you sell, trade, or spend it, you pay Capital Gains Tax on the difference between your purchase price and sale price. When you earn crypto — through mining, staking, or airdrops — it's taxed as income at its fair market value.
Do I need to report crypto losses?
Yes. Even if you only made losses, you're still required to report them. But it's actually in your favour — reported losses can offset your gains and reduce your tax bill, both this year and in future years.
Does the IRS know if I sold crypto?
Yes. As of 2026, all centralized exchanges are required to issue Form 1099-DA, which reports your crypto sales and disposals directly to the IRS. Exchanges also complete KYC checks and have handed over user data to tax authorities in the past.
Can you legally avoid paying tax on crypto?
You can't avoid it entirely, but you can reduce it significantly. Tax-loss harvesting lets you offset gains by selling losing positions. Holding for over a year qualifies you for lower long-term rates. And the biggest one: making sure your cost basis is accurate — it's the number one reason crypto investors overpay.
Do I need crypto tax software if I got a 1099-DA?
Yes. Form 1099-DA reports your proceeds to the IRS, but cost basis is often missing or incorrect — especially if you've moved crypto between platforms. Without it, you could significantly overpay. Crypto tax software like Koinly tracks your full history and calculates the correct gains and losses.
How can Koinly help with my crypto taxes?
Koinly calculates your cryptocurrency taxes by connecting to 800+ exchanges and wallets and importing your full transaction history — including DeFi, staking, and NFTs. It flags missing cost basis, identifies tax savings, and generates ready-to-file reports for TurboTax, your accountant, or the IRS — helping you pay less tax next year.
