Crypto Tax Questions, Answered Plainly

The stuff people search at 11pm the night before the deadline.

How are crypto gains taxed in the US?

The IRS treats crypto as property. Selling for dollars, swapping one coin for another, or spending crypto on anything is a taxable event. Gains on assets held one year or less are short-term and taxed at your ordinary income rate. Gains on assets held more than one year are long-term and taxed at 0, 15, or 20 percent depending on your income. Losses offset gains, and up to $3,000 of net loss offsets ordinary income each year.

What is Form 1099-DA and why does it matter now?

Form 1099-DA is the IRS form that US crypto brokers must send to you and the IRS. It reports gross proceeds from sales starting with tax year 2025, and cost basis for assets acquired from 2026 onward. The IRS now has a number to match against your return. If you skip reporting or your numbers disagree with the exchange's, expect a notice. Full guide here.

Can I calculate my crypto taxes for free?

For a simple estimate, yes, use the calculator above. For a real Form 8949 covering every wallet, exchange, swap and airdrop, you need software or a very patient spreadsheet. All four platforms above let you import everything and see your gains before you pay for the downloadable report.

Which software is best for DeFi, staking and NFTs?

Koinly and CoinTracker have the broadest chain and protocol coverage. CoinLedger is the simplest if most of your activity is on centralized exchanges. ZenLedger is the pick if a CPA will finish your return. Check the integrations page of each for your exact chains before committing.

Do I owe tax if I only swapped coins and never cashed out?

Yes. A crypto-to-crypto swap is a sale of the coin you gave up, at its dollar value at that moment. This surprises more people than anything else in crypto tax.

What if I have losses?

Report them. Capital losses offset capital gains dollar for dollar, then up to $3,000 per year against ordinary income, and the rest carries forward. Unreported losses are money you are leaving with the IRS.
