An Australian Ether (ETH) holder was considering solo staking, but he wanted to understand the tax risk before committing. His biggest concern was, What happens if ETH falls sharply after he receives staking rewards but before he sells them?
He used a hypothetical example to work it out. Suppose ETH is worth $100,000 when he receives his staking rewards. At that point, the value of those rewards can count as taxable income. If he receives two ETH over the year, that could leave him with a large income tax bill.
The problem comes if ETH falls before he pays that tax. In his example, ETH drops from $100,000 to $30,000. He would then have to sell more ETH to raise enough cash for the tax bill. That sale could also create a capital gains tax liability.
After running through the numbers, he estimated that he could end up with less than $10,000, despite selling around $120,000 worth of ETH.
His question was: “Please tell me I am wrong.”
Unfortunately, the risk he identified is real. It comes from the way staking rewards can be taxed in Australia: the rewards may create a tax liability when their value is much higher than when the investor eventually sells them. That can leave stakers with a tax bill even when the value of their crypto has fallen significantly.
How Staking Rewards are Taxed
Staking rewards are taxed as ordinary income the moment they land in your wallet, based on their AUD market value at that exact time, the same way any other staking income is treated. It doesn’t matter whether you sell the reward, hold it, or watch it lose most of its value a few months later. The tax is calculated on what it was worth when it arrived, full stop.
“There are two types of taxability on this kind of income,” says Ankush Kumar, a crypto tax and accounting analyst at KoinX. “As and when you receive staking rewards, airdrops, liquidity pool income, or interest, that’s taxable as miscellaneous income straight away.”
“Later, whether the price appreciates or depreciates doesn’t matter for that first amount,” he adds. “That later movement becomes part of capital gain or capital loss, not part of the original income.” Staking creates two separate tax events on the same tokens: an income event at receipt, and a completely separate capital gain or loss event whenever you actually dispose of them.
Working Out the Numbers
Here’s the maths from the original post, checked.
Event | Calculation | Amount |
Staking rewards received (2 ETH at $100,000 each) | Assessable as ordinary income | $200,000 |
Income tax owed on that income (2024-25 resident rates, no other income assumed) |
| $56,138 |
ETH price by year end |
| $30,000 |
ETH sold to raise cash for the tax bill | 4 ETH × $30,000 | $120,000 |
Capital gains tax on that sale (assuming a low original cost base on the principal holding) |
| $40,000–$54,000 |
Cash left after both bills are paid | $120,000 − $56,138 − $54,000 | $9,862
|
The income tax figure isn’t rounded or approximate. It matches Australia’s actual 2024-25 resident tax brackets applied to $200,000 of assessable income almost to the dollar.
The capital gains hit on top of it comes from a detail easy to miss: solo staking requires locking up 32 ETH, so the four coins sold to cover the bill are very likely part of that original holding, bought long before the price ever reached $100,000. Even after crashing to $30,000, those coins can still sit well above their original cost base, which means selling them to raise cash triggers a real, separate capital gain.
Calculating the Tax on the Sale
Where the price is set for a staking reward depends on what’s being received. “There are two conditions,” Kumar explains. “If the token is already listed on an exchange with an established price, like Ethereum, the value the moment it lands in your wallet is your cost base.”
“But if it’s an initial allocation of a token that isn’t listed anywhere yet, and it only gets listed later, the cost basis is treated as zero,” he adds. ETH falls squarely into the first category, already priced, already liquid, so the $100,000 figure in this scenario is a straightforward, defensible cost base, not an edge case.
Once that reward is later sold, any movement from that cost base is capital gain or capital loss, and it stays separate from ordinary income in a way that matters here. “That capital gain or capital loss can’t be adjusted against income,” Kumar says. “Going forward, if your capital gains for the year aren’t enough to cover your capital losses, the loss can be carried forward indefinitely.”
That’s a real feature, but it’s cold comfort in the middle of a cash crunch. A carried-forward loss reduces a future tax bill. It does nothing for the one due this year.
Is He Wrong? Not Really
The scenario is deliberately a stress test: a large reward valued right near a local peak, followed by a sharp drop before tax time. But the mechanism behind it isn’t hypothetical. It’s exactly how the ATO treats every staking reward, at any size.
What makes solo staking sharper than smaller, more frequent staking is concentration. A handful of large reward events valued at a specific moment carry more risk than the same total value spread across many smaller ones, simply because there’s less averaging and less chance to react before a big chunk of the year’s income gets locked in at a high price.
There’s also a wrinkle in how often that “moment” actually happens. Restaking or auto-compounding doesn’t reduce the number of taxable events, it can increase them. “If you stake Ethereum and receive an ETH reward, and then that reward itself gets automatically staked, the new position that opens is treated as a new position,” Kumar says. Each one carries its own receipt date and its own cost base, which means an auto-compounding strategy can quietly generate far more individual tax events across a year than the two round numbers in this scenario suggest.
What Can Be Done About It
There is no way to avoid the tax on staking rewards simply because their value falls later. The safer approach is to plan for the tax bill when the reward is received.
In practice, this means:
- Set aside money for tax when you receive each reward. This can be kept in cash or a stablecoin so you don’t have to sell ETH later if the price falls.
- Base the reserve on your expected tax rate. Use your expected marginal tax rate rather than setting aside an arbitrary amount.
- Keep track of auto-compounded rewards separately. Each new reward can create its own taxable event, so the tax reserve should account for these as well.
These steps do not reduce the tax you owe. They simply ensure that you have funds available when the tax bill arrives, rather than having to sell crypto at a lower price to pay it.
Seeing This Coming Before It's a Crisis
The gap in this scenario is about visibility. Nobody sees a $56,138 liability building up in real time while it’s happening. It shows up all at once, at tax time, long after the price has already moved.
The real problem for a staker isn’t just knowing that staking rewards are taxable. It’s knowing how much taxable income those rewards have accumulated to date, especially when the value of ETH is moving constantly.
This is where KoinX can help. By connecting the wallet or exchange where staking rewards are received, users can track each reward, assign an AUD value to it, and keep a running record of their staking income instead of trying to reconstruct it at tax time.
Guna Shekar Proddaturi, KoinX’s founding engineer, explains that the platform values each reward as it arrives. “We try to get the most accurate price available in the market,” he says. “In case that’s not found, we fall back to a one-hour window to check the average. If even that isn’t found, then we take the daily average.”
That means the value isn’t based on what ETH is worth months later when the investor finally sells. Each reward is recorded against the market value available when it was received.
How KoinX Tracks Staking Rewards
- Connect the wallet or exchange where the rewards arrive.
Whether rewards come from a solo validator, staking pool, or exchange, connecting the relevant wallet or platform allows KoinX to identify and track the staking transactions. - Each reward is valued when it is received.
KoinX records each staking reward separately and assigns it a value based on the available market price. If an exact price isn’t available, the platform uses the fallback pricing method Proddaturi describes: a one-hour average, followed by a daily average if necessary. - See your staking income building throughout the year.
Instead of discovering the total only when preparing the tax return, users can see the value of their staking rewards as they accumulate. This can give them a clearer number to work with when planning how much money to keep aside for tax. - Keep the tax reserve separate from the crypto.
Once the income figure is visible, the investor can use their expected marginal tax rate to estimate how much cash or stablecoin to reserve. This is particularly useful in a scenario like the Reddit post, where ETH falls sharply after the rewards have already created taxable income. - Use the report when preparing the tax return.
KoinX does not determine the final tax payable because that depends on the investor’s complete tax position and other income. Instead, it provides the transaction and income information needed for the return. As Proddaturi explains, “You have to put those gains into your income tax return forms, which then calculates how much you owe.”
The benefit is visibility. A staker can see the value of rewards accumulating during the year, rather than waiting until tax time to discover that a large amount of income has already been recognised.
That doesn’t remove the tax liability or protect against a fall in ETH. But it can make the liability easier to track and gives the investor time to set aside funds before a price drop turns a tax obligation into a cash-flow problem.
That sequence is the practical version of the cash-reserve habit Kumar describes. One shows the number building before it’s due. The other makes sure there’s something set aside to meet it, so a falling price doesn’t force a sale to cover a bill that visibility could have flagged months earlier.
The Redditor’s fear wasn’t overblown, it was the correct read of a genuinely awkward rule. The one thing actually within his control is deciding now, before the first reward lands, whether he’s going to track its value as it arrives or find out the hard way at tax time.
