For U.S. federal income-tax purposes, digital assets such as cryptocurrency, stablecoins, and NFTs are generally treated as property. Selling or exchanging a digital asset you held as a capital asset can create a taxable capital gain or loss; simply holding it does not. This guide covers transactions completed during calendar year 2025, generally reported on returns filed in 2026. State and non-U.S. tax rules may differ.
Do I have to pay taxes on crypto if I sell it?
Possibly. The IRS says, “Digital assets are treated as property, and the general tax principles applicable to all property transactions also apply to transactions involving digital assets.” The IRS added that statement to its digital-asset FAQ on Dec. 15, 2025. If you sell a capital asset for dollars, you generally calculate gain or loss by comparing the amount realized with your adjusted basis. Whether the result is taxable, and how it is treated, depends on the asset’s classification and transaction details. IRS digital-asset FAQs
A sale is not the only transaction that can matter. Exchanging property held as a capital asset for digital assets that differ materially in kind or extent can also result in a recognized gain or loss under the IRS’s general property rules. By contrast, receiving digital assets as income, compensation, or through a business activity is a separate tax question, not automatically a capital gain. A transfer between your own wallets is not necessarily a sale, but the records linking the units across accounts can matter when you later dispose of them.
How do I calculate crypto capital gains?
For a capital-asset disposition, the basic calculation is the amount realized minus adjusted basis. Amount realized generally reflects what you received in the transaction, while basis generally reflects your investment in the units disposed of, adjusted as required. Transaction-level details—including dates, units, values, fees where applicable, and how the assets moved between accounts—are needed to support the calculation. Do not assume a broker’s proceeds figure is itself your gain.

- Purchase and disposition dates and the number of units involved.
- Transaction values and applicable fees.
- Records showing how assets moved among brokers, accounts, and wallets, so the units disposed of can be connected to their acquisition history.
- Any broker tax forms and the underlying transaction history, checked against one another.
Basis-identification rules depend on the holding arrangement and transaction date. The IRS’s current digital-asset FAQs address post-2024 transactions; its separate virtual-currency FAQs generally apply to transactions completed before Jan. 1, 2025. For a 2025 disposition, use the current FAQ provisions that match your custody arrangement and circumstances rather than automatically applying an older FAQ method.
Is swapping one cryptocurrency for another taxable?
An exchange can be a disposition for federal tax purposes. The IRS states that exchanging property held as a capital asset for digital assets that differ materially in kind or extent can produce a recognized gain or loss. Do not treat a crypto-to-crypto swap as tax-free merely because no U.S. dollars changed hands. The specific result depends on what was exchanged, how the property was held, and the transaction’s facts. Other digital-asset activity—including staking, lending, liquidity provision, gifts, mining, and business or compensation receipts—can involve distinct rules and is outside this general capital-gains overview.

What is Form 1099-DA, and what changed for 2025?
Form 1099-DA is an information return used by brokers to report digital-asset transaction information. For transactions effected on or after Jan. 1, 2025, brokers generally report gross proceeds. Basis reporting for certain transactions begins for transactions effected on or after Jan. 1, 2026, so a form covering a 2025 sale may report proceeds without basis. The IRS said on Jan. 28, 2026: “Most of these statements will not include the basis for DA transactions in 2025 and taxpayers will have to calculate basis to determine their gain or loss.” IRS tax tip on 2025 tax documents
The reporting rules apply to brokers that take possession of digital assets being sold, including custodial trading platforms and certain other providers; they do not mean that every exchange, wallet, or transaction will generate a Form 1099-DA. For 2025, the filing requirements generally apply to U.S. brokers, so taxpayers using a foreign broker may not receive one. The IRS also identifies certain transaction categories subject to temporary broker-reporting exceptions. Those are information-reporting exceptions, not blanket tax exemptions. See the IRS digital-assets reporting page and its Form 1099-DA overview.
What a 2025 form may—and may not—tell you
| Information situation | What it means for your records |
|---|---|
| Form 1099-DA reports gross proceeds but no basis | Use your own transaction history to establish basis and calculate gain or loss; proceeds alone do not complete the calculation. |
| You do not receive Form 1099-DA | You may still have taxable transactions to report. A missing form does not remove the reporting obligation. |
| You receive a form | Compare it with your full transaction records rather than treating it as a complete tax calculation. |
The IRS instructs taxpayers to report income, gains, and losses whether or not they receive an information form. Its digital-assets guidance and Form 1099-DA explanation describe reporting and the form’s role.
How do I report digital-asset capital gains on my 2025 tax return?
For individuals, the IRS generally directs taxpayers to calculate sales and other capital transactions involving digital assets on Form 8949, then summarize capital gains and deductible losses on Form 1040, Schedule D. Follow the 2025 versions of the forms and instructions, which govern returns generally filed in 2026. The IRS notes that an exception may apply when a broker has provided a Form 1099-DA with both gross proceeds and basis information; check the applicable current-year instructions for how to report that transaction. IRS digital-asset FAQs
This filing path concerns capital transactions. Non-business ordinary income from digital assets is a separate reporting question and should not be folded into a capital-gains calculation. For complex histories spread across wallets and brokers, tax-preparation or reconciliation software can be an optional way to organize transaction records and prepare tax reports, but it does not replace checking basis, classification, or the applicable IRS instructions.

The IRS’s older virtual-currency FAQs generally address transactions completed before Jan. 1, 2025. The newer digital-asset FAQs address transactions completed in 2025 and later. That date distinction matters for guidance on identifying basis and reporting transactions; do not carry an older method forward without checking the current FAQ provision that fits your transaction and custody arrangement.
