Crypto-to-Crypto Trade Taxable Gain

Use the price at the exact timestamp of the trade, from a reputable exchange or a price aggregator. For a trade that executed over a period of time, a volume-weighted average price over the execution window is the most defensible figure. Avoid using the daily close, the price on a different exchange, or a value you happen to remember — each of these introduces a discrepancy that can be challenged. Most exchanges publish historical price data to the minute, and many provide a downloadable trade history that already includes the USD value at execution.

Cost basis is what you paid to acquire the asset, including the purchase price plus any acquisition fees such as exchange commissions, and adjusted for any events that change your investment in the asset. For an asset bought in several lots, the basis of the units you dispose of depends on your accounting method: FIFO uses the oldest lots, LIFO the newest, and specific identification lets you choose. Airdrops and hard forks generally take a basis equal to their fair market value at receipt, which is also the amount you recognise as income at that time.

In many jurisdictions, yes — this is called specific identification, and it is one of the few legitimate levers available. By choosing to dispose of the lot with the highest basis, you reduce the realised gain, sometimes to zero or a loss. The catch is that specific identification generally requires contemporaneous documentation: you must be able to show which specific units were disposed of at the time of the trade, not reconstruct the choice after the fact. In some jurisdictions it must also be elected on your return. Consult a tax adviser before relying on it.

A loss is a realised capital loss, and in most jurisdictions it can offset realised capital gains in the same tax year. If losses exceed gains, many countries allow the excess to be carried forward to offset future gains, and some allow it to offset a limited amount of ordinary income. This is why tax-aware traders deliberately harvest losses near the end of a year: disposing of a position that is underwater converts an unrealised paper loss into a usable deduction. Be aware of wash-sale rules in the US, which can defer the loss if you acquire a substantially identical asset within 30 days before or after the sale.

It depends on the jurisdiction. In the US, assets held for more than one year qualify for long-term capital gains rates, which are 0%, 15% or 20% depending on income, versus short-term gains taxed at ordinary income rates up to 37%. Germany exempts crypto held for more than a year entirely. Australia applies a 50% discount to gains on assets held at least 12 months. The UK and Canada make no distinction by holding period. Because the thresholds differ, the practical rule is to know the rule that applies to you before you trade.

Report every disposal individually, not just the net figure. Most tax authorities require line-by-line reporting of each trade with its date, the asset disposed of, the proceeds, the cost basis and the resulting gain or loss. The net gain is then carried to the summary schedule. Reporting only the net is a common shortcut that can trigger questions during review, and it makes it harder to substantiate the figures if asked. Good crypto tax software produces the line-by-line report automatically from exchange exports.

Yes. The asset you receive takes a cost basis equal to its fair market value at the moment of the trade — which is the same figure you used as the FMV in this calculation. That is the symmetry that makes the whole system work: the gain you recognised on the outgoing asset becomes the starting basis for the incoming asset, so you are not taxed twice on the same appreciation. If you later dispose of the incoming asset at a higher price, only the appreciation from the swap date is taxed. Record the new basis and the acquisition date, since the latter drives your holding period.
