Quick answer
If you receive new tokens from a hard fork or an airdrop and you have dominion and control over them (that is, you can transfer, sell, or otherwise dispose of them), the fair market value (FMV) of those tokens at the time you first have control is taxable ordinary income. That FMV becomes your initial cost basis for future capital gain or loss when you later sell, exchange, or spend the tokens. (See IRS Notice 2014-21 and Revenue Ruling 2019-24.)
Why this matters
Cryptocurrency is treated as property for U.S. federal tax purposes (IRS Notice 2014-21). That means ordinary income rules apply when you receive tokens as compensation, through airdrops, or when you obtain immediate control after a fork. Later sales or exchanges produce capital gains or losses reported on Form 8949 and Schedule D. Misreporting the timing or value of income from forks and airdrops is a common audit trigger.
How forks and airdrops differ for tax purposes
-
Forks: A hard fork splits a blockchain and can create a new, separate token. The tax result depends on whether you receive and control the new asset. If you have no access (no dominion and control), you generally don’t recognize income at the moment of the chain split. If you do have control, the FMV when you first control the tokens is taxable ordinary income. (Rev. Rul. 2019-24)
-
Airdrops: Tokens distributed for free to holders are generally taxable when you receive them if you have dominion and control. The FMV when you receive the airdrop is ordinary income. If tokens are distributed in connection with services or as compensation, treat them as compensation (self-employment income if you’re an independent contractor or income reported on a W-2 if you’re an employee).
Author’s note: In my tax practice I’ve seen taxpayers treat both events as non-taxable until sale — that’s incorrect if you had control at receipt. Always confirm whether you could immediately transfer or sell the new tokens.
Determining ‘dominion and control’ (practical checklist)
The IRS doesn’t use one bright-line test, but in practice you can ask:
- Could I transfer or sell the new tokens immediately after the event? (Yes = likely taxable)
- Did the exchange or custodian credit the new tokens to an account I could access? (Yes = likely taxable)
- Did the project require steps before I could claim the tokens (e.g., register, provide private keys)? (If yes, you may not have had dominion and control yet.)
Keep contemporaneous records: screenshots, exchange notices, emails, transaction IDs, and timestamps showing when tokens became accessible.
How to value tokens at receipt
- Use a reliable exchange price at the date and time you first had dominion and control. If no active market exists, use a reasonable valuation method and document it (e.g., price of comparable tokens, median of multiple exchanges).
- Record the date, UTC timestamp, and the price source.
- If you later find the initial valuation was incorrect, consult a tax professional about amending your return; minor differences are common but larger errors invite scrutiny.
Caveat: If tokens are illiquid or thinly traded, valuation can be subjective; documenting your method is critical for audit defense.
Tax reporting steps (practical workflow)
- Identify the event and the date you first had dominion and control.
- Determine the FMV at that moment — this is ordinary income and the cost basis.
- Report ordinary income on your Form 1040. If it’s not compensation from employment or business, report it as “Other income” on Schedule 1 (Form 1040), unless you received a Form W-2 or are self-employed (then Schedule C and self-employment tax may apply).
- Track the holding period: It starts on the day after you acquired the tokens (the date you had dominion and control) for capital gains purposes.
- When you sell, exchange, or spend the tokens, report the sale on Form 8949 and Schedule D, using the basis you recorded at income recognition. (See our detailed guide: Tax Consequences of Selling Cryptocurrency: Reporting and Records.)

Examples (realistic scenarios)
1) Hard fork with immediate control
You held 1.0 BTC before a hard fork and, immediately afterward, the exchange credited you with 1.0 NEWBTC which you could withdraw the same day. NEWBTC’s market price at that moment was $300. You must report $300 as ordinary income and set your basis in NEWBTC to $300.
2) Airdrop with delayed access
A project airdrops tokens to holders, but the tokens are held by the project and you must claim them by completing identity verification. You do not have dominion and control until you complete the claim. Taxable income arises when you take control.
3) Compensation vs. windfall
If tokens were paid for services (consulting, development), treat the FMV as compensation at receipt and report as business income (Schedule C) or wages (W-2), depending on your relationship.
Common mistakes to avoid
- Treating receipt as non-taxable until you sell. If you had dominion and control earlier, income is recognized at receipt.
- Failing to document how you determined FMV.
- Using inconsistent valuation sources (use the same exchange or a clear composite method).
- Reporting airdrops as capital gains instead of ordinary income when appropriate.
What forms to expect
- Schedule 1 (Form 1040) — Other income: for airdrops or forks not connected to a trade or business.
- Schedule C and Schedule SE — If token receipt is business income (mining, payment for services).
- Form 8949 and Schedule D — Report capital gains or losses when you later sell, exchange, or spend the tokens.
- Keep supporting records (exchange statements, blockchain records, valuation notes) for at least three years, and ideally seven.

Recordkeeping checklist (what I ask clients to keep)
- Date and UTC timestamp when tokens were credited to your account or wallet.
- Source of valuation (exchange name, price, URL, and screenshot).
- Transaction IDs and wallet addresses.
- Any communications from exchanges or projects about the event.
- Evidence of when you first could transfer or sell the tokens.
Good recordkeeping reduces stress during audit or amended-return discussions.
When to get professional help
- You received large or multiple airdrops/forks and valuation or timing is unclear.
- You used multiple wallets and exchanges and cannot reconcile basis.
- You received tokens linked to services, which may trigger payroll or self-employment tax.
In my experience, an initial consultation with a CPA who understands crypto tax saves more in time and potential penalties than DIY corrections later.
Bottom line
Airdrops and forks can create taxable income when you have dominion and control over the new tokens. The FMV at that point is ordinary income and becomes your basis for future capital events. Document everything, use consistent valuation sources, and report ordinary income on the appropriate lines of Form 1040. For sales, use Form 8949 and Schedule D.
