The U.S. Internal Revenue Service (IRS) has issued critical guidance clarifying how taxpayers should handle income from cryptocurrency hard forks and airdrops. Released in October 2019 as Revenue Ruling 2019-24 and accompanying frequently asked questions (FAQs), this update builds on the agency’s original 2014 crypto tax framework and provides much-needed clarity for individuals holding digital assets.
Understanding these rules is essential for anyone involved in the crypto space—whether you're a long-term holder, trader, or investor. Failure to comply could result in underpayment penalties, audits, or other tax liabilities.
What the IRS Guidance Covers
The 2019 update primarily addresses two key scenarios:
- Tax treatment of virtual currency received through a hard fork
- Tax obligations when airdropped tokens are distributed following a blockchain split
This guidance confirms that receiving new cryptocurrency via an airdrop after a hard fork constitutes taxable income under U.S. tax law.

Key Definitions: Virtual Currency, Cryptocurrency, and Hard Forks
Before diving into the tax implications, it's important to understand the IRS’s definitions:
Virtual Currency
According to the IRS, virtual currency is a digital representation of value that functions as:
- A medium of exchange
- A unit of account
- A store of value (other than U.S. or foreign fiat currency)
Cryptocurrency
A subset of virtual currency, cryptocurrency uses cryptographic techniques to secure transactions recorded on decentralized ledgers like blockchain. These are commonly referred to as coins or tokens.
Hard Fork
A hard fork occurs when a change in a blockchain’s protocol creates a permanent divergence in the ledger. As a result, a new version of the blockchain emerges—potentially creating a new cryptocurrency.
For example, Bitcoin Cash was created after a hard fork from the original Bitcoin blockchain.
Airdrop (Distribution)
An airdrop refers to the distribution of new cryptocurrency tokens to multiple wallet addresses on a distributed ledger. While often associated with hard forks, not all forks lead to airdrops.
Crucially, the IRS distinguishes between merely having access to new tokens and actually receiving them.
When Does Taxable Income Occur?
The IRS ruling hinges on one central concept: receipt of cryptocurrency.
Scenario 1: Hard Fork Without Airdrop
If a hard fork occurs but no new tokens are distributed to your wallet, no income is recognized. You simply continue holding your original cryptocurrency without any tax consequences at that time.
Example: Alice holds 50 units of Coin M. A hard fork creates Coin N, but no N tokens are sent to Alice’s wallet. She does not receive N and therefore has no taxable event.
Scenario 2: Hard Fork With Airdrop
If new cryptocurrency is distributed to your wallet—and you have control over it—you must recognize ordinary income equal to the fair market value of the tokens at the time of receipt.
Example: Bob holds 50 units of Coin R. After a hard fork, 25 units of new Coin S are airdropped to his wallet. At the moment the transaction is recorded on the blockchain, Coin S has a market value of $50. Bob must report $50 as gross income for that tax year.
His cost basis in the 25 S coins is also $50—the amount used to calculate future capital gains or losses when he sells or trades them.
Control Matters: When Are Tokens “Received”?
One of the most nuanced aspects of the ruling involves constructive receipt and control.
Even if tokens appear in your wallet, you haven’t “received” them for tax purposes unless you can exercise dominion and control—meaning you can transfer, sell, exchange, or otherwise dispose of them.
Example: Exchange Wallet Limitations
Suppose an airdrop sends new tokens to your exchange-based wallet, but the platform doesn’t support that token yet. You can’t withdraw or trade it. In this case, you do not have control, so no income is recognized until such functionality becomes available.
Once the exchange enables trading or withdrawal, that date becomes your official receipt date—and the fair market value at that time determines your taxable income.

Core Tax Principles Applied
The IRS applies established tax doctrines to digital assets:
- Section 61(a)(3) of the Internal Revenue Code: Defines gross income as all income from whatever source derived, including gains from property transactions.
- Section 1011: Determines adjusted basis for calculating gain or loss upon sale.
- Section 451: Governs when income is recognized based on accounting method (cash vs. accrual).
These provisions confirm that cryptocurrency received through an airdrop is treated like any other form of property income—fully includible in gross income upon realization.
Frequently Asked Questions (FAQ)
Q1: Do I owe taxes if I didn’t actively claim the new coins?
Yes—if the airdropped tokens were delivered to your wallet and you had control over them, it’s a taxable event regardless of whether you took action.
Q2: How do I determine the fair market value of an airdropped token?
Use the trading price on reputable exchanges at the time the token was received. If no active market exists, use a reasonable valuation method and document your approach.
Q3: What if I lost access to the airdropped coins?
You still recognize income upon receipt. Later loss doesn't reverse the initial tax liability, though it may qualify as a capital loss if sold or deemed worthless.
Q4: Are all hard forks taxable?
No—only if new cryptocurrency is actually received via distribution. A protocol split alone doesn’t trigger taxation.
Q5: Can I defer this income?
Not under current U.S. tax law. The income must be reported in the year of receipt using cash-basis accounting (the standard for most individual taxpayers).
Q6: How should I report this on my tax return?
Report the fair market value as “other income” on Form 1040 Schedule 1. Keep detailed records: blockchain transaction hash, date, value in USD, and wallet address.
Why This Matters for Crypto Investors
With increasing regulatory scrutiny, accurate tax reporting is no longer optional. The IRS treats crypto like property—not currency—which means every acquisition, disposal, and receipt triggers potential tax consequences.
Ignoring airdrop income may seem minor, but aggregated over time and across users, such omissions can attract audit attention—especially as blockchain analytics tools make transaction tracing easier than ever.
