Crypto Tax Glossary

Plain-English definitions for the terms that come up when figuring out crypto gains and losses. Not tax advice -- just the vocabulary.

Airdrop
Free tokens sent to a wallet, often for promotion or as a reward for prior activity. In many jurisdictions, the fair market value at receipt is taxable income, and that value also becomes your cost basis for a later sale.
Capital Gain
The profit made when you sell, trade, or spend an asset for more than its cost basis. The opposite is a capital loss.
Capital Loss
The loss incurred when you dispose of an asset for less than its cost basis. Often usable to offset capital gains, subject to local rules.
Cost Basis
What you originally paid for an asset (price plus, in some regimes, associated fees). Gain or loss is calculated as proceeds minus cost basis.
Disposal
Any event that ends your ownership of an asset in a way that can trigger a taxable gain or loss -- selling for cash, trading for another crypto, or spending it.
Fair Market Value (FMV)
The price an asset would sell for on the open market at a given moment -- used to value income events like airdrops, mining, and staking rewards.
FIFO (First-In-First-Out)
A cost-basis matching method that assumes the oldest units of an asset are the ones sold first. The default assumption in many jurisdictions absent specific identification.
HIFO (Highest-In-First-Out)
A cost-basis matching method that sells the most expensive lot first, which minimizes the reported gain (or maximizes the reported loss) for that sale.
Holding Period
The length of time between acquiring and disposing of an asset. Determines whether a gain is classified as short-term or long-term.
LIFO (Last-In-First-Out)
A cost-basis matching method that assumes the most recently acquired units are the ones sold first.
Long-Term Capital Gain
A gain on an asset held for longer than the jurisdiction's long-term threshold (more than one year in the US). Usually taxed at a lower rate than short-term gains.
Proceeds
The value received when you dispose of an asset -- the sale price, or the fair market value of whatever you received in a trade.
Realized Gain/Loss
A gain or loss that has actually occurred because you disposed of the asset -- as opposed to an unrealized gain/loss, which is just a paper change in value while you still hold it.
Short-Term Capital Gain
A gain on an asset held for the jurisdiction's short-term threshold or less (one year or less in the US). Often taxed as ordinary income.
Specific Identification
A cost-basis method where you explicitly choose which lot you're selling at the time of sale, instead of defaulting to FIFO/LIFO/HIFO. Usually requires detailed, contemporaneous records.
Staking Rewards
Tokens earned for participating in a proof-of-stake network's validation. Commonly taxed as income at fair market value when received, which then becomes their cost basis.
Taxable Event
Any transaction that can trigger a tax consequence -- selling, trading, spending, or (in many regimes) receiving income like staking rewards or airdrops. Simply buying and holding is not one.
Unrealized Gain/Loss
A paper gain or loss on an asset you still hold -- the price has moved, but nothing has been reported for tax purposes yet because there's been no disposal.
Wash Sale
Selling an asset at a loss and quickly buying it back to claim the loss while keeping the position. Some jurisdictions disallow the loss in this case for stocks; whether the same rule applies to crypto varies and is an evolving area -- check current guidance.
