What is a crypto airdrop?
Tokens that show up unasked can be a genuine distribution, a taxable event, or bait. Telling them apart starts with knowing how each works.

A crypto airdrop is a distribution of tokens to many wallet addresses at once, often without the holders doing anything. Some follow a chain split or a launch; many unsolicited ones are scams pointing to fake sites. In the US, airdropped tokens you control are generally taxable income.
How does a crypto airdrop work?
The IRS, in Revenue Ruling 2019-24, defines an airdrop simply as a way of distributing units of a cryptocurrency to the ledger addresses of many people. Because a token's balances are recorded on the blockchain, the sender only needs your address; you do not have to accept anything.
One well-known case is the airdrop that follows a hard fork: when a chain splits, holders of the old coin may receive units of the new one. Projects also use airdrops to spread a new token among early users. Ethereum.org warns that the same mechanism is cheap to abuse, because a token contract can write almost any balance it likes into your wallet.
Are airdropped tokens taxable?
In the United States, yes in most cases. The IRS says that if you receive new cryptocurrency from an airdrop after a hard fork, you have ordinary income equal to its fair market value when the transfer is recorded on the ledger — provided you have "dominion and control", meaning you can sell or move it. That value also becomes your cost basis. Rules differ by country; see how crypto is taxed and check with a tax professional.
How do fake airdrops steal crypto?
In June 2025 the FBI warned that criminals were sending unsolicited NFT airdrops whose memo field carried a link. The site asked victims to connect their wallet and enter their seed phrase, then emptied it. Ethereum.org describes the same playbook with tokens: lookalike names and clone websites that push you to approve token allowances or send funds.
| Sign | Usually genuine | Red flag |
|---|---|---|
| How you learn of it | The project's official channels | A token or NFT appears with a link in its name or memo |
| What it asks for | Nothing, or a claim on the official site | Your seed phrase, or an approval on an unfamiliar site |
| Token details | Contract address matches official sources | Same name as a real token, different contract |
What mistakes do people make with airdrops?
- Clicking the link inside a token. Leaving an unknown token alone is far safer than interacting with it.
- Signing approvals in a hurry. Read token approvals explained first.
- Typing a seed phrase into a website. No real airdrop needs it — see seed phrases explained and common crypto scams.
Questions readers ask
Do I need to do anything to receive an airdrop?
Often not: the tokens are written to your address. Some projects require you to claim on their site, which is exactly where clone sites strike, so reach it only through official links.
Is a soft fork taxable like an airdrop?
According to the IRS FAQ, no: a soft fork does not create a new cryptocurrency, so you receive nothing new and have no income from it.
An airdrop is just a mass token transfer. Genuine ones can still create a tax bill; fake ones are bait. Verify through official channels, never share a seed phrase, and keep records of what you received and its value on the day.
