A messy crypto history, sorted out.
Thousands of swaps, several wallets, lost CSV files. We trace your history all the way from the chain and hand you a finished report that can be attached to your tax return or claim for adjustment as it is.
We never ask for your recovery phrase, keys or passwords — for the diagnosis, an exchange transaction export and a public wallet address are enough.

Just one is reason enough to get it sorted.
You meant to sort it out when you had time, and that was two years ago.
You swapped one coin for another dozens of times, because it didn't feel like selling.
The old phone that had your wallet on it is lost.
You tried to work it out in Excel and gave up at the third tab.
You made a loss and reported nothing, because you thought you didn't have to.
You reported something, but you don't know if it was right.
In all of these the outcome is the same: the figures exist, but they are scattered. Nothing is lost — putting it together just takes time and the right tools.
Correcting it is voluntary only for a while.
Your own reporting obligation has applied all along. What is new is that crypto service providers became subject to a reporting obligation from the start of 2026 — and once the data starts flowing to the Finnish Tax Administration (Verohallinto), a voluntary correction turns into a response.

Your own reporting obligation
Disposals of crypto assets have been taxable and reportable all along. This did not change in 2026 and will not change in 2027 — past years must be reported too.
Exchanges became subject to reporting
Domestic and foreign service providers began collecting users' identification and transaction data for reporting. What is new is not your obligation but the fact that the data now travels without you.
Correct it yourself
For a voluntary correction made after the tax assessment has closed, the tax increase (penalty surcharge) is 0.5 % of the added income instead of the usual 2 %. For repeated neglect it is 3–10 %.
The data is transferred
Exchanges report 2026 purchases, sales and transfers per crypto asset — from abroad too.
Requests for clarification
Comparison with what was reported begins. Past years are still open, but the cost and effort are a different matter.
