Your crypto tax return, done properly.
We reconcile every wallet, exchange and chain for the tax year, apply UK rules, and give you SA108 figures ready to file yourself or hand to an accountant.
Returns for 2025-26 are due 31 January 2027. For that deadline, we need your data by 8 January.
We will never ask for passwords, API keys or seed phrases.

Something else, such as NFTs, liquidity pools, lending or coins lost to a hack? Tell us at the free check and we'll say plainly whether we can do it, and what it would cost.
Trading bots and more than 10,000 transactions in a year are quoted individually.
Filing, checks and earlier years
Filing it
File it yourself, use your own accountant, or one of our partner accountants can review your pack, advise and file it for you. We don't give tax advice or file returns ourselves.
Already use Koinly or similar? Keep it.
Send us the report it produced and we'll check it for the usual problems: unmatched transfers, missing costs and rules applied the US way. You get written findings for £99, deducted if you then want the full pack.
Get your report reviewedLost money on crypto? It could cut your tax bill.
A crypto loss can reduce tax on future gains, but only if you claim it within four years of the end of the tax year. Many people never do. Every pack lists your losses and their deadlines.
Earlier years never reported?
We rebuild earlier years too, each additional year from 50% of the tier when done with your current year, so you or your accountant can put things right with accurate figures.
HMRC letters and correctionsPrice
One fixed price per tax year, set by what you did, not how many transactions you made: Core £249, Active £449, Advanced from £649. Agreed at the free check, before any work starts.
