Tax on Crypto Casino Winnings: The Win, the Disposal, and the Gap Between Them

The win: outside tax, by two routes

HMRC's business income manual states the basic position in a sentence: betting and gambling, as such, do not constitute trading. A player's winnings are therefore not trading income. The capital gains legislation closes the other door: winnings from betting are not chargeable gains. Between them, a casino win is generally outside tax in the player's hands, whichever game produced it and whatever the operator's licence.

The tax on gambling falls on the operator. Remote Gaming Duty is charged on a licensed operator's profits from remote gaming, at a rate raised to 40 % this spring, and nothing is deducted from a player's withdrawal to pay it. An overseas operator's position under the duty is its own affair; the player's position is unchanged.

The disposal: what the cryptoassets manual governs

HMRC's cryptoassets manual addresses what happens when a person sells, exchanges or spends cryptoassets. It states that HMRC does not consider the buying and selling of cryptoassets to be the same as gambling, and that whether an activity amounts to gambling is a question of fact. A sale of an asset for pounds, a swap of one asset for another, and the use of an asset to pay for something are each a disposal, measured for capital gains purposes against the asset's value when it was acquired.

For a casino player this manual is about the leg after the win: the moment the withdrawn asset becomes pounds at an exchange, or is swapped for a stablecoin, or is spent. The manual does not address casino winnings; it addresses the asset once it is yours.

The gap: what neither manual says by name

No HMRC text names a casino win paid in crypto. Two inferences follow from reading the manuals together, and both are inferences.

First inference. The win is gambling, because the business income manual's position does not depend on the currency the win is paid in. A win credited in Bitcoin is a gambling win in Bitcoin.

Second inference. The asset, once credited, is a cryptoasset you hold, and anything you do with it afterwards is governed by the cryptoassets manual. The acquisition value for a later disposal would, on this reading, be the asset's sterling value when it was credited to you.

Both inferences are cautious in the sense that they assume the more demanding reading where the manuals are silent. The alternative readings are not absurd: one could argue that an asset received as a gambling win has no acquisition cost and is wholly a gain on disposal, or that a stablecoin pegged to a currency is for practical purposes money and a swap into it is not a disposal at all.

The manuals support neither reading in terms, and a page that adopted either would be guessing in the reader's favour, which is the wrong direction to guess about tax. A reader with a large balance or an unusual pattern of play should take the two manuals, and this page's reading of them, to an adviser rather than to a casino comparison site.

Moments on the route where something may happen

• Buying the asset at an exchange — What happens: Pounds become crypto · Tax position on the cautious reading: An acquisition; no tax event
• Depositing at the casino — What happens: Crypto moves to the operator's address · Tax position on the cautious reading: No disposal; the balance is a claim on the operator
• Winning — What happens: Balance grows · Tax position on the cautious reading: Gambling; outside tax for the player
• Withdrawing to your wallet — What happens: Asset credited to you · Tax position on the cautious reading: An acquisition at that day's value, on the cautious reading
• Selling for pounds — What happens: Crypto becomes pounds · Tax position on the cautious reading: A disposal under the cryptoassets manual
• Swapping for a stablecoin — What happens: One asset becomes another · Tax position on the cautious reading: A disposal under the cryptoassets manual Two rows deserve a note. The deposit row assumes the balance at the casino is a claim rather than a holding, which is how a cash balance at any casino is treated; the cryptoassets manual does not address casino balances. And the swap row is the one that catches players who move winnings into a stablecoin to escape price risk: on the manual's reading the swap is itself a disposal, measured against the value at withdrawal.

Price movement between win and sale

The gap between a win and a sale is where the asset's price does its work, and it is the gap the second inference measures. Win when the asset is worth one figure and sell when it is worth another, and the difference is a gain or a loss on the cautious reading, separate from the win itself.

Converting promptly after a withdrawal shortens the gap; playing in a stablecoin narrows it to the peg currency's movement against sterling; neither removes it. A player who holds winnings for weeks waiting for a better price has turned a gambling result into an investment position, and the manuals treat the two differently, which is one more reason the sale belongs close to the win. The Gambling Commission names fluctuation against fiat among the risks a licensee must manage before accepting crypto, and the FCA's guidance on crypto as an asset warns of sudden market moves; both are descriptions of the same gap from the regulator's side.

Bonuses, rakeback and the tax position

A bonus credited by the operator, and winnings from it, are part of the gambling balance and sit on the win side of the line on the cautious reading.

Rakeback and cashback, which return a share of stakes or losses, are credits from the operator in the course of gambling and sit on the same side; we describe them as a discount on losses and not as income, and the advertising code bars presenting gambling as a way to make money. None of this changes what happens when the asset is later sold, which is the cryptoassets manual's territory.

Records that make a later calculation possible

• Exchange purchase confirmations, with date, amount in pounds and amount of asset: the acquisition values for the assets you deposited.
• Casino withdrawal confirmations, with date and amount of asset, and a note of the asset's sterling price that day: the acquisition values for winnings, on the cautious reading.
• Transaction IDs for every transfer in either direction.
• Exchange sale confirmations, with date, amount of asset and pounds received: the disposal values.
• Swap records, where one asset became another, with values on the day.

The same file answers a casino's source-of-funds request, which the Gambling Commission's guidance says may include bank statements, and it answers HMRC if a disposal ever has to be computed. Kept from the first purchase, it takes minutes; reconstructed afterwards, it may not be possible. Exchange statements can usually be exported for a date range, and a wallet's transaction history can be read from a public explorer at any time, so the raw material survives even when the habit lapsed.

What this page is not

It is not tax advice, and it does not know your circumstances. It reports what two HMRC manuals say, states the reading that follows where they are silent and labels it, and lists the records that any reading would need.

A player whose winnings are large, who trades the asset as well as gambles with it, or whose pattern of activity might look like trading rather than gambling, has a question of fact that the cryptoassets manual says is decided case by case, and that is a question for an adviser. You must be 18 or over to gamble in Great Britain, and the National Gambling Helpline, run by GamCare, is free on 0808 8020 133 at any hour.

Frequently asked questions

Are casino winnings taxed in the UK?

Generally not, for the player. HMRC's business income manual holds that betting and gambling do not constitute trading, and the capital gains legislation excludes gambling winnings from chargeable gains. The operator pays Remote Gaming Duty on its own profits.

Does that change if I am paid in crypto?

No rule says so by name. The cautious reading is that the win is still gambling, and that what you do with the asset afterwards, a sale or a swap, is a disposal under HMRC's cryptoassets manual with its own possible consequences.

What is a disposal?

Selling the asset for pounds, exchanging it for another asset, or using it to pay for something. HMRC's cryptoassets manual treats each as an event for capital gains purposes, calculated against what the asset was worth when you acquired it.

What was my crypto worth when I won it?

The sterling value at the moment it was credited to you, which is why a record of the withdrawal date and the price that day matters. HMRC's manual works from acquisition values, and a win paid in crypto is an acquisition at that day's value on the cautious reading.

Do I pay tax on a stablecoin win?

The same position applies: the win is gambling, and a later sale of the token is a disposal. A pegged token moves little against its peg currency but can move against sterling, which is the gain or loss the manual would measure.

Is Remote Gaming Duty deducted from my withdrawal?

No. It is an operator's tax on its own profit, paid by licensed operators, and nothing is taken from a player's balance.

Where do the sources go quiet?

On a casino win paid in crypto specifically, and on how a win should be valued for a later disposal. Both are inferences from the two manuals rather than statements in them, and this page labels them as such.
