Your dead tokens are worth money. Claim them.
Every crypto portfolio with a few years on it holds corpses, the rugged, the delisted, the long abandoned. Most people scroll past them with a wince. The wince is worth actual money, a negligible value claim under section 24(2) TCGA 1992 crystallises the loss while you still hold the asset, no sale needed, no finding a buyer for the unbuyable.
What the claim is worth on your own figures
The loss is the easy part. What matters is the tax it actually saves, and whether part of it is burnt against an allowance you were getting anyway. Both are below. It runs on this page in your browser, nothing you type is transmitted or stored.
Nothing is computed until the figures are real. Still needed:
- What the token cost you
- What it is worth now, zero is a figure
- Your other gains this tax year
- Your income
Computed in your browser at 2026 to 2027 rates, nothing transmitted, the copy link keeps your figures after the # where browsers never send them. A loss of the current year is set against that year's gains in full, before the £3,000 allowance, which is why the wasted figure exists at all.
How it works, in one paragraph
You claim that the asset has become of negligible value while you have owned it. The claim treats you as having sold and immediately reacquired it at that negligible value, which realises the loss, and the loss offsets gains in the normal way. The claim can name an earlier date, up to two years back under the conditions, which can land the loss in a year where it meets real gains. The full mechanics and a worked example live in the deep guide.
Does the claim look available on your facts?
Four conditions, plus the backdating test if you want an earlier date. Tick what is true. This is a computation on what you tick, not advice, and nothing you tick leaves this page.
The backdating window is counted from your own clock, so it is right whatever day you read this. A computation on what you ticked, not personal tax advice.
The app finds the candidates for you
Import your history and the engine flags holdings whose value has collapsed against cost, then generates the claim letter with the figures from your own records, highlighted for you to confirm before anything is filed. What most people forget to claim, the software refuses to forget.
Find your dead tokensCommon questions
What is a negligible value claim?
A claim under section 24(2) TCGA 1992 that an asset you still hold has become worth next to nothing. It crystallises the loss without a sale, and the loss then offsets gains like any other.
My token still technically trades at a fraction of a penny, does that count?
Possibly. Negligible is not zero, HMRC accepts claims where value has become negligible relative to cost. A dead project trading at dust on one venue is a classic candidate, evidence matters.
Can I backdate the claim?
A claim can specify an earlier date, up to two years before the start of the tax year in which you make it, provided the asset was already of negligible value then. That can move the loss into a year where it offsets real gains.
What evidence should I keep?
What the token cost you, what happened to the project, and what it was worth at the claim date, screenshots and the app’s working paper cover it. The claim letter the app generates leaves the figures highlighted for you to confirm.
Can the loss be wasted?
Yes, and it is the trap nobody mentions. A loss of the current year is set against the gains of that year in full, before the £3,000 annual exempt amount, so a claim in a quiet year can burn the allowance and save nothing. The calculator on this page shows exactly how much would be wasted.
Does the calculator send my figures anywhere?
No. It runs on this page in your browser, nothing is transmitted or stored. The copy link button keeps your inputs after the # in the URL, the part browsers never send to any server.
