The IRS classifies cryptocurrency as property, not currency — a distinction established in Notice 2014-21 and reinforced in subsequent guidance. This means every time you dispose of crypto, you potentially trigger a capital gain or loss, just as if you had sold a stock or real estate. The tax treatment depends on how long you held the asset and whether you made a profit.
What the IRS Says About Crypto
The IRS treats each unit of cryptocurrency as a separate property with its own cost basis and holding period. Virtual currency received is reported as income at fair market value. Gains and losses from dispositions are capital gains and losses, subject to the same short-term and long-term rules as securities.
Form 1040 has explicitly asked about virtual currency activity since 2019. Answering “No” when you have had taxable crypto transactions is a position that creates legal risk.
Taxable Events
A taxable event occurs whenever you dispose of crypto or receive it as income. Common taxable events:
1. Selling Cryptocurrency for Cash
Selling any crypto for dollars (or any fiat currency) triggers a capital gain or loss.
Example: You bought 1 ETH for $1,800 and sold it for $3,200. Your capital gain is $1,400. If held more than one year, it qualifies for long-term rates. If held one year or less, it is taxed as ordinary income.
2. Trading One Cryptocurrency for Another
Exchanging Bitcoin for Ethereum is a taxable event — even though no dollars change hands. The IRS treats it as selling the first crypto at its current fair market value and buying the second.
Example: You trade 0.1 BTC (cost basis $2,500) for ETH worth $4,100. You realize a $1,600 capital gain at the time of the swap.
This is the most commonly missed taxable event. Every trade on an exchange creates two transactions: a disposition of the original asset (potentially triggering a gain) and an acquisition of the new asset (establishing a new basis).
3. Using Crypto to Pay for Goods or Services
Spending cryptocurrency to buy goods or services is treated as a sale at fair market value on the date of the transaction.
Example: You pay 0.05 ETH (cost basis $75) for a purchase when ETH is worth $3,000 per unit (0.05 × $3,000 = $150 fair market value). You realize a $75 capital gain.
4. Receiving Crypto as Income
Crypto received as compensation — whether from an employer, as a freelance payment, or as a reward — is treated as ordinary income at the fair market value on the date received. This income is also subject to self-employment tax if received for services.
- Mining rewards: Ordinary income at fair market value when received
- Staking rewards: Ordinary income at fair market value when received (consistent with IRS guidance in Rev. Rul. 2023-14)
- Airdrops: Ordinary income at fair market value if you have dominion and control over the new tokens
- Hard fork proceeds: Ordinary income at fair market value when received
The fair market value at the time of receipt becomes your cost basis for future dispositions.
5. DeFi Transactions
Decentralized finance (DeFi) transactions are still evolving from a regulatory perspective, but many create taxable events:
- Providing liquidity: Depositing tokens may be treated as a disposition; receiving LP tokens may establish a new basis
- Yield farming / liquidity mining: Reward tokens are likely ordinary income when received
- Borrowing against crypto: Generally not a taxable event if structured as a loan; however, liquidations are taxable
- Wrapped tokens: Converting BTC to wBTC or similar wrappers may be treated as a like-kind exchange (position varies) — treat conservatively as taxable
Non-Taxable Events
These transactions do not trigger immediate tax liability:
| Transaction | Why Not Taxable |
|---|---|
| Buying crypto with cash | Acquisition, not a disposition |
| Holding crypto | No realization event until disposed |
| Transferring between your own wallets | No change in ownership |
| Gifting crypto (under the annual exclusion) | Gift tax rules apply; capital gain deferred to recipient |
| Receiving crypto as a gift | Not income; use giftor’s basis if known |
| Donating crypto to a 501(c)(3) charity | Deduction at fair market value; no capital gain recognized |
Transferring between your own wallets is particularly important: moving crypto from one exchange to another, or to a self-custody wallet, is not a taxable event — it is merely changing custody. However, you must track the cost basis accurately across wallets to correctly calculate gain or loss when you eventually sell.
Cost Basis Methods
When you have purchased the same cryptocurrency at different times and prices, you must choose a cost basis method to determine which units you are selling. The IRS permits several methods for crypto, similar to securities:
| Method | Description | Best For |
|---|---|---|
| FIFO (First In, First Out) | Oldest units sold first | Default; works if you have few purchases |
| HIFO (Highest In, First Out) | Highest-cost units sold first | Minimizes current-year gain |
| LIFO (Last In, First Out) | Newest units sold first | Sometimes beneficial in falling markets |
| Specific Identification | Choose exact lots to sell | Maximum control over gain/loss |
HIFO is generally the most tax-efficient method when disposing of appreciated crypto — it sells your highest-cost units first, reducing the size of the taxable gain. However, you must be able to identify the specific units; proper exchange records and crypto tax software make this feasible.
Important: The method must be applied consistently per asset (though you can use different methods for different assets). Once you choose a method and apply it, changing it can attract IRS scrutiny.
Holding Period: Short-Term vs. Long-Term
The same rules that apply to stocks apply to crypto:
- Short-term: Held one year or less — taxed at ordinary income rates (10%–37%)
- Long-term: Held more than one year — taxed at preferential rates (0%, 15%, or 20%)
This is the single most powerful lever for reducing crypto taxes: holding for at least one year and one day before disposing converts ordinary income rates to long-term capital gains rates.
Reporting: Form 8949 and Schedule D
Every taxable crypto transaction must be reported on Form 8949 (Sales and Other Dispositions of Capital Assets). You must report:
- Description of asset
- Date acquired
- Date sold
- Proceeds (what you received, in USD)
- Cost basis (what you paid, in USD)
- Gain or loss
Gains and losses are then summarized on Schedule D and flow to Form 1040.
Brokerages are required to issue Form 1099-B for securities. For crypto, Form 1099-DA (Digital Asset Proceeds from Broker Transactions) was introduced to require reporting starting with 2025 transactions. Crypto exchanges will need to report to the IRS and send forms to users, similar to stock brokerages.
Even before mandatory broker reporting, the IRS has been matching data from exchanges via subpoenas and John Doe summonses. Not reporting crypto gains is detectable.
Crypto Tax Software
Crypto tax software such as Koinly, CoinTracker, TaxBit, and TokenTax can connect to exchanges and wallets via API or CSV import to automatically calculate gains, losses, income, and generate Form 8949. Given the complexity of tracking thousands of small transactions, mining income, and DeFi activity, these tools are often essential for active crypto users.
The Wash Sale Rule and Crypto
As noted, the wash sale rule currently does not apply to cryptocurrency under existing IRS regulations (which apply only to “stocks and securities”). This means you can sell crypto at a loss and immediately repurchase to reset your basis — capturing the tax loss without missing potential upside.
This gap in the law has been the subject of proposed legislation repeatedly. Be aware this may change, particularly if legislative action occurs.
Key Takeaways
- The IRS treats crypto as property: every disposal is a capital gain or loss event.
- Taxable events: selling for cash, trading crypto-to-crypto, spending crypto, receiving crypto as income (including mining and staking rewards).
- Non-taxable: buying, holding, transferring between your own wallets, receiving gifts.
- Use HIFO or specific identification for cost basis to minimize reportable gains in appreciated positions.
- Hold for more than one year to qualify for long-term capital gains rates (0%–20%) instead of ordinary income rates (up to 37%).
- Report on Form 8949 and Schedule D; Form 1099-DA reporting from exchanges begins with 2025 transactions.
- The wash sale rule does not currently apply to crypto — you can harvest losses without a 30-day waiting period.
