Two taxable events, not one
The November 2024 genesis distribution sent HYPE to roughly 94,000 eligible wallets — at the time one of the largest airdrops in crypto by value. Whatever your allocation was, the standard US treatment creates two separate events:
Receipt — an airdrop is generally treated as ordinary income at the moment you gain dominion and control over the tokens, valued at fair market value. That FMV becomes your cost basis in the lot. Sale or disposal — when you later sell, swap or spend the tokens, the difference between proceeds and that basis is a capital gain or loss, with its own holding period starting at receipt.
Miss the first event and your basis collapses to zero — every later sale reports the entire proceeds as gain. Report only the first and you have an income line with no matching disposition, which is its own red flag to a preparer.
Where the math breaks in practice
FMV at what moment? HYPE began trading at distribution, so a price existed from the first block — but the price in the first minutes differed sharply from hours later. The timestamp you anchor to changes the ordinary-income number materially. Whatever you pick, it must be defensible and consistent.
Multiple wallets, multiple receipts. Each eligible address that claimed is a separate receipt event with its own FMV snapshot — allocations can't be pooled into one income line with a single price.
Staking and ecosystem rewards that followed are separate income events at their own receipt FMVs — they don't inherit the airdrop's basis. And a spot token received by airdrop has no purchase fill anywhere: to a tool that only reads trades, that inventory looks like it appeared from nothing — the 'phantom lot' case, where basis has to come from outside the trade history.
The honest edge cases
When does 'dominion and control' start — eligibility announcement, claim availability, or your actual claim transaction? Filers take different positions; the answer affects both the timing and the FMV of the income. If you never claimed, there may be no receipt at all.
If you sold immediately on receipt, income and disposition land in the same window and largely offset — but they are still two lines on the return, not one net number.
Basisproof doesn't decide these positions for you. The paid report's basis chain records spot inventory that arrived without a purchase as its own category, and CEX/basis evidence can inject a known cost where you have one. What the venue ledger proves is stated; what needs your tax position is left open.
Common questions
?Is the HYPE airdrop taxable?
Under the standard US treatment, yes — airdrops are ordinary income at fair market value when you gain control of the tokens, and that FMV becomes your cost basis. The timing and amount are the contested details.
?What if I never claimed the airdrop?
Income generally requires dominion and control — an unclaimed allocation may not be income until claimed. Whether it still sits unclaimed is visible on-chain; the position you take is a question for your preparer.
?I sold my airdrop right away — do I owe twice?
You report two events, not double tax: ordinary income at receipt FMV, then a small capital gain or loss on the difference between FMV and your sale price. Same window, two lines.
?Why does my tax tool show my HYPE as 'missing basis'?
Airdropped tokens have no purchase fill — a trade-history importer sees inventory appear from nowhere and either zeroes the basis or flags it. The basis has to come from the FMV-at-receipt determination, which is outside trade data entirely.
Basis for what the chain can't price
The paid report's basis chain carries airdropped and transferred-in inventory as its own category — never invented, never silently zeroed. Upload exchange evidence to inject real cost where it exists.
