Capital gain: what it means for crypto tax

A capital gain is the profit on a disposal: your proceeds minus the asset's cost basis. If you dispose of a coin for more than it cost you, the difference is a capital gain that may be taxable depending on your country and your total gains for the year.

General information, not tax advice. Crypto tax rules differ by country and change over time, verify against your country's guidance or a qualified advisor.

An example

Buy 1 BTC for 20,000, sell it for 30,000, and you have a 10,000 capital gain, taxed under your country's capital gains rules.

Why it matters for your tax

Capital gains are the main thing crypto investors are taxed on. How much you owe depends on the holding period, your other income, and any allowances, so the gain itself is only the starting figure.

CryptaTax handles this automatically across your wallets and exchanges, so the concept is applied consistently without you tracking it by hand. Try the crypto tax calculator →

Capital gain: what it means for crypto tax

Definition in context

A capital gain is the profit you make when you dispose of an asset for more than its cost basis. In crypto, a disposal includes selling for fiat, trading for another cryptocurrency, or using crypto to pay for goods or services. The gain is calculated as the proceeds (the value of what you receive) minus the cost basis (what you originally paid, including fees). Capital gains are typically taxed at a different rate than income, and the rate may depend on how long you held the asset.

Why it matters to crypto records

Every time you dispose of crypto, you may realize a capital gain or loss. You need to track the cost basis of each asset and the proceeds from each disposal to calculate your gains accurately. This is essential for tax reporting. If you don't track your basis, you might overpay tax by assuming your entire proceeds are gain. Also, you need to know the holding period, as some jurisdictions offer lower tax rates for long-term gains. Keeping detailed records of every transaction, including dates, amounts, and fees, is critical.

Record example

You buy 0.5 ETH for $1,000 (including fees) on January 1. On June 1, you sell that 0.5 ETH for $1,500. Your capital gain is $1,500 - $1,000 = $500. If you had held the ETH for more than a year, you might qualify for a lower long-term capital gains rate. If you trade ETH for another crypto, the fair market value of the crypto you receive is your proceeds. For example, if you trade 0.5 ETH (worth $1,500) for 2 BTC, your proceeds are $1,500, and your gain is $500.

Distinctions and next steps

Capital gains are different from ordinary income, which includes things like salary, interest, and staking rewards. In crypto, mining and staking rewards are often taxed as income at receipt, and then any subsequent gain or loss on those coins is a capital gain or loss. To manage your capital gains, consider tax-loss harvesting: selling assets at a loss to offset gains. But be aware of wash sale rules if applicable. Use a crypto tax software to automatically calculate your gains, but ensure you understand the methodology. Keep records of your cost basis and proceeds for at least the required number of years.

A careful next step

Before acting on this term, return to the original record and write down the question it raises: what changed, which source proves it, and whether another related concept describes the event more accurately. Keep that note with the export or wallet evidence. It makes a later review faster and avoids turning a short label into an unsupported conclusion about tax, accounting or reporting.
