The starting point: crypto is property, not currency
For US federal tax purposes, the IRS treats convertible virtual currency as property, not as foreign currency. This classification has broad consequences: many transactions involving crypto trigger tax treatment similar to buying and selling stock or other property, rather than simple currency exchange.
What counts as a taxable event
Common examples include:
- Selling crypto for US dollars.
- Trading one crypto asset for another (for example, exchanging bitcoin for ether) — this is treated as a disposal of the first asset.
- Using crypto to pay for goods or services — treated as a sale of the crypto at its fair market value at the time of the transaction.
- Receiving crypto as income, such as through mining, staking rewards, or as payment for work — generally taxed as ordinary income based on fair market value when received.
What generally is not a taxable event
- Buying crypto with US dollars and holding it.
- Transferring crypto between wallets you own and control.
- Donating crypto to a qualified charity (subject to its own specific rules).
Calculating gains and losses
When a taxable disposal occurs, the general calculation is:
Proceeds − cost basis = capital gain or loss
Cost basis is generally what was paid to acquire the asset, including fees. Holding period determines the tax rate category.
| Holding period | Classification | General federal tax treatment |
|---|---|---|
| One year or less | Short-term capital gain/loss | Taxed at ordinary income rates |
| More than one year | Long-term capital gain/loss | Taxed at long-term capital gains rates |
| N/A — received as income | Ordinary income | Taxed at ordinary income rates on receipt |
Rates and specific thresholds change periodically and depend on overall taxable income, so figures should always be checked against current guidance rather than assumed to remain fixed.
Recordkeeping challenges specific to crypto
Because a single wallet can accumulate many small transactions — trades, transfers, staking rewards, network fees — reconstructing an accurate transaction history can be more complex than with a typical brokerage account. Useful records to retain include:
- Date and time of each transaction.
- Fair market value in US dollars at the time of each transaction.
- Cost basis of assets acquired.
- Records of transfers between the taxpayer's own wallets, to avoid double-counting them as disposals.
- Any fees paid, which can adjust cost basis or proceeds.
Choosing a cost-basis method
Taxpayers holding multiple lots of the same asset acquired at different times and prices generally need to identify which lot is being sold. Common methods include first-in-first-out and specific identification, where supported by adequate records. The method used can materially affect the calculated gain or loss on a given sale.
Reporting
US taxpayers are generally required to answer a digital asset question on their federal income tax return and, where applicable, report capital gains and losses and any crypto-related income on the appropriate forms. Some exchanges issue informational tax forms, but coverage and completeness have varied, particularly for activity across multiple platforms or wallets.
Special situations
- Staking and mining rewards typically create both an income event on receipt and a separate capital gain or loss event when the rewards are later sold.
- Hard forks and airdrops may create taxable income when new tokens are received and the taxpayer has control over them.
- Losses, including from exchange failures or theft, are subject to specific rules and limitations that differ from ordinary capital losses.
Key takeaways
- The IRS treats crypto as property, so most disposals are treated similarly to sales of other capital assets.
- Trading one crypto asset for another is a taxable event, not a tax-free exchange.
- Cost basis and holding period determine the size and character of any gain or loss.
- Detailed, transaction-level recordkeeping is essential given how fragmented crypto activity can be across wallets and platforms.
- This is general information, not personalized tax advice; specific situations should be reviewed against current IRS guidance or with a qualified tax professional.
