For U.S. federal income tax purposes, buying cryptocurrency with dollars and simply holding it generally do not trigger a taxable sale. Selling, swapping, spending, or otherwise disposing of a digital asset can create a taxable gain or loss. The calculation usually depends on the asset’s adjusted basis, what you received, transaction costs, and how long you held it. Receiving crypto as income is a separate tax event from selling it later.
What the federal tax rules cover
This guide covers U.S. federal income tax treatment for individuals, not state, local, or foreign tax rules. The IRS treats digital assets as property: “the general tax principles applicable to all property transactions also apply to transactions involving digital assets,” according to IRS FAQ 48, added December 15, 2025. The IRS’s broad digital-asset category includes cryptocurrency, stablecoins, and non-fungible tokens (NFTs), but the asset’s classification and the nature of a transaction can affect its treatment.
What happens when you buy and hold crypto
Buying with dollars
When you buy a digital asset with U.S. dollars, the purchase price generally establishes your basis in the asset, subject to adjustments required by the circumstances. Record the acquisition date and time, quantity, dollar value, and relevant transaction costs. Buying with real currency alone is not generally a disposition.
Holding through a price change
An increase or decrease in market value while you continue to hold the asset does not, by itself, amount to a sale or disposition. That change matters for the eventual tax calculation if you dispose of the asset.

Moving assets between your own wallets
A transfer between wallets or accounts you own or control is generally not itself a disposition. Keep records showing that the transfer was between your own accounts. If you pay a transfer fee in digital assets, however, the units used for the fee may be treated as a separate disposition.
How to calculate gain or loss when you sell
For a digital asset held as a capital asset, the general calculation is:
Gain or loss = amount realized − adjusted basis
Adjusted basis is generally what you paid for the units, with applicable adjustments. Amount realized can include cash and the fair market value of property or services received. Eligible digital-asset transaction costs allocable to effecting the disposition reduce the amount realized. The IRS digital-asset FAQs discuss commissions and network or “gas” fees paid for services to effect a purchase, sale, or disposition. A cost to move assets between your own wallets is treated differently from a cost that effects a purchase or sale.

For example, if you sell capital-asset units for more than their adjusted basis after accounting for eligible disposition costs, the difference is generally a gain. If the amount realized is lower, the difference is generally a loss. The exact result depends on the facts and how the units sold are identified.
Which units did you sell?
If you acquired the same digital asset at different prices and sell only some of it, the basis and holding period depend on which units are treated as sold. IRS guidance distinguishes broker-custodied accounts, hosted wallets, and unhosted wallets; do not assume a single FIFO rule applies across every account or wallet.
For broker-custodied units sold after December 31, 2025, IRS guidance requires specific identification to be communicated to the broker by the sale’s date and time, using identifiers the broker accepts and keeping adequate records. If the applicable specific-identification requirements are not met, the default generally uses the earliest-acquired units in the relevant account or wallet. See the IRS FAQs on digital-asset transactions for the rules that apply to the custody and transaction context.
How holding period affects a capital gain or loss
For a capital asset, a gain or loss is generally short-term if you held the asset for one year or less, and long-term if you held it for more than one year. The IRS describes the period as running from the day after acquisition through the date of disposition. Holding period classification does not by itself determine your tax rate; your full circumstances and applicable law matter. For details, consult the IRS FAQs and the relevant return-year instructions.
Other crypto activity that can affect your taxes
| Activity | General federal tax treatment |
|---|---|
| Buying with real currency, then holding | Generally not a disposition by itself. |
| Selling for dollars | Generally a disposition; a capital-asset sale can produce a gain or loss measured using amount realized and adjusted basis. |
| Swapping one digital asset for another | Can be a disposition of the asset given up, even when you receive no dollars. |
| Paying for goods or services with crypto | Can be a disposition of the digital asset used for payment. |
| Paying a transaction fee in crypto | The units used or withheld may themselves be disposed of; the treatment depends on the transaction. |
| Mining, staking, rewards, awards, or payment for services | May create ordinary income when received; a later sale or exchange can create a separate gain or loss. |
| Transfer between wallets or accounts you control | Generally not a disposition, though a fee paid in digital assets may be one. |

Records to keep
Good records help establish both basis and the result of each transaction. Keep information for purchases, receipts, sales, exchanges, transfers, and fees, including:
Rank #4
- Acquisition and disposition dates, times, and quantities.
- Fair market value in U.S. dollars when assets were received or disposed of.
- Purchase price and other information needed to calculate adjusted basis.
- Cash, property, or services received in a disposition, plus eligible transaction costs.
- Wallet and account details, transfer records, and any unit-identification records.
- Records supporting any income reported when you received digital assets.
These details are especially important when you move assets among exchanges and wallets, because a broker’s proceeds information may not establish your basis.

The digital-asset question on an individual federal return asks whether, during the tax year, you received digital assets as a reward, award, or payment for property or services, or sold, exchanged, or otherwise disposed of a digital asset or a financial interest in one. The answer depends on the specific return-year wording and your activity.
The IRS says taxpayers who only bought digital assets with real currency or only held them generally answer “No.” Listed receipts, sales, exchanges, payments, and other dispositions generally call for “Yes.” A self-transfer is generally not enough on its own, but a fee paid in digital assets can change the analysis. Check the instructions for the tax year you are filing on the IRS pages for how to answer the digital-asset question and digital assets.

Individuals generally report applicable capital-asset dispositions on Form 8949 and summarize results on Schedule D. The 2025 Instructions for Form 8949 direct digital-asset transactions to the relevant digital-asset boxes for short- or long-term transactions. Ordinary income from activities such as mining or staking may instead go on Schedule 1 or another applicable form, depending on the circumstances.
What Form 1099-DA tells you—and what it may not
For digital-asset sales in 2025 made through a broker, the IRS said customers might receive Form 1099-DA during the 2026 filing period. In Tax Tip 2026-07, dated January 28, 2026, the IRS said brokers must send the statement to customers by February 17, 2026. It also warned that most statements for 2025 transactions would not include basis, so taxpayers would need acquisition records to calculate gains or losses.
A Form 1099-DA is not a substitute for working out and reporting your taxable activity. The IRS says taxpayers must report related income, gains, or losses whether or not they receive the form. Compare broker information with your own purchase, transfer, and disposition records, and check current IRS instructions for the tax year you are filing.
When extra help may be useful
Tax software or a qualified tax professional may be useful if you have activity across multiple wallets or exchanges, missing basis records, income from mining or staking, or uncertainty about how a transaction should be classified. A software-generated report can help organize activity, but it does not replace checking the source records or determining the correct tax treatment. If your transactions are complex or records are incomplete, consider getting advice from a tax professional familiar with digital assets.
