Each reward is an income event
Hyperliquid staking is delegated proof-of-stake: you delegate HYPE to validators, and rewards accrue to your staked balance roughly every reward cycle — on the order of daily. They auto-redelegate, so a balance that compounds all year is a sequence of discrete credits, not one growing number.
Under the standard US treatment (Revenue Ruling 2023-14), staking rewards are ordinary income at fair market value when you gain dominion and control over them, and each credit's FMV becomes the basis of that lot. A year of daily compounding is roughly 365 separate income lines and 365 lots — each needing its own price at its own timestamp.
When you later sell or swap that HYPE, the difference between proceeds and the lot's basis is a capital gain or loss with its own holding period. Skip the income line and your basis collapses toward zero — the same trap as the genesis airdrop, except it repeats every day.
What isn't a taxable event
Moving HYPE between your spot and staking accounts, delegating to a validator, undelegating, and the 7-day unstaking queue that carries balance back to spot — none of these are disposals. You're moving your own tokens between your own balances; the basis rides along.
The trap is in the tooling, not the chain. A software model that treats every ledger movement as a transfer-out can misread an unstake as leaving your custody — and then misread the re-entry as new inventory with no basis. The queue makes it worse: a staking-to-spot withdrawal finalizes up to 7 days after you request it, so the two halves of one transfer can land in different weeks of your data.
The honest question sits on the rewards themselves: are auto-redelegated credits 'under your control' before you could undelegate them? Delegations carry a 1-day lockup, so there is a defensible argument for treating each credit as income when it lands versus when it becomes withdrawable. Filers take different positions — it's a timing-of-income question for your preparer, not something the chain settles.
Why rewards are invisible to trade data
This is the part that breaks every generic importer: staking rewards are not trades. They never appear in your fill history, your funding stream, or your spot transfers. The venue exposes them through separate endpoints — delegatorSummary, delegatorHistory and delegatorRewards — that no fill-based importer ever calls.
So a tool that reads your trade history sees unstaked HYPE sell with no purchase anywhere in the record — phantom inventory, same as an airdrop — and reports zero or missing basis on every sale of reward-funded balance. The income events are absent entirely.
Basisproof reads the same public streams and doesn't pretend the gap away: spot inventory with no matching acquisition is carried as unknown basis in the paid report's basis chain, never silently zeroed or guessed. Where you have evidence for the FMV at receipt, the CEX/basis upload injects it. What the venue's own rewards endpoints state is noted; what requires your tax position stays open.
Common questions
?Are HYPE staking rewards taxable?
Under Revenue Ruling 2023-14, yes — staking rewards are ordinary income at fair market value when you gain dominion and control. Each reward credit is a separate event with its own FMV and its own basis lot.
?Is unstaking or undelegating HYPE taxable?
No — moving your own tokens between your own spot and staking balances isn't a disposal. The 7-day unstaking queue just delays finalization; basis carries through the whole round trip.
?Rewards auto-compound — when exactly are they income?
The mainstream reading is when each credit lands in your staked balance. Because delegations carry a 1-day lockup, some filers argue income only when rewards become withdrawable — a legitimate timing question for your preparer.
?Why does my tax tool show 'missing basis' on HYPE I unstaked and sold?
Staking rewards never appear in trade history — they're not fills. An importer reading only trades sees HYPE materialize with no purchase and either zeroes the basis or flags it. The basis has to come from FMV-at-receipt evidence outside the trade stream.
Inventory that arrived without a trade
The paid report's basis chain carries reward-funded and transferred-in inventory as its own category — flagged as unknown basis, never invented. Upload evidence to inject real cost where you have it.
