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.

diagnosis, which also tells you if you don't need us
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.
You don't get an estimate. You get a document.
The result is a ready-to-sign report for each tax year: a summary, the fields to enter in MyTax (OmaVero), the calculation principles with legal references, data sources, the deadline — and, as an appendix, every disposal line by line with a transaction ID that can be checked in a blockchain explorer.
Every disposal, one FIFO lot at a time
Acquisition date, holding period, disposal price, actual acquisition cost and deemed acquisition cost side by side — and which one was chosen.
MyTax fields ready
By tax year, in exactly the form the figures are entered in MyTax: Capital gains › Add a new disposal › asset type Crypto assets.
Which losses are still usable
Losses to be confirmed, their deduction period year by year, and those that are not deductible at all. More often than not, this pays for the work.
Reconciliation to on-chain balances
After the calculation, the remaining lots are compared with the wallets' actual balances. If transactions were missing, the balance would not match. This is the difference between a calculation and a guess.
Methodology statement
Which sources were used, what was missing, what was estimated and on what basis. This is the document you present if questions are asked.
Four steps, one fixed price
Diagnosis
You send an exchange transaction export and one wallet address. You get an estimate of the size of the mess and a fixed price.
Material
You get an exact list of what to fetch and from where, with exchange-specific instructions. The only step that takes your time.
Reconstruction
We fetch the transactions from the chain, link the wallets, fill the gaps and calculate the disposals on a FIFO basis.
Walkthrough
We go through the result with you, and you get a ready-to-sign report along with a recommended course of action.
Fixed price, agreed before work starts
The diagnosis tells you the level and the price. If the case turns out heavier than estimated, we pause and offer you options — we don't bill surprises afterwards.
The promotional prices are valid until the end of the year. The reason is in the calendar. Crypto service providers have been collecting your transaction data since 1 Jan 2026 and will report it to the Tax Administration for the first time in January 2027. So this is the last autumn when you can sort out your history at your own pace — from next spring the data will already be with the other side. Your price is locked in the offer and does not change during the work.

Extended or Chain Reconstruction? The difference is in the starting data. With Extended you know all your wallets and exchanges, and we build the calculation from them. With Chain Reconstruction some of the funds have passed through wallets or chains you no longer remember, so they are traced first. The diagnosis tells you which one is enough.
Chain Reconstruction tiers
Every tier includes the full content of Chain Reconstruction. A larger history adds more, and the price per transaction falls: a 15 000-transaction reconstruction costs under 6 cents per transaction. The transaction count comes out in the diagnosis, so you know your tier before you decide anything.
- Full content of Chain Reconstruction
- 30-min walkthrough
- Per-token summary: where the gains and losses came from
- 60-min walkthrough
- Per-token summary and 60-min walkthrough

The struck-through figure is the regular price; the lower one is the promotional price, valid until 31.12.2026. If the Finnish Tax Administration (Verohallinto) later sends a request for clarification, we help with the response at 165 €/h. Prices are final, including VAT: the invoice total is the same as on the price list and nothing is added on top. Tax calculation software costs 49–399 € per tax year and leaves the work to you. With us, you know the price before you hand anything over.
How many transactions does your wallet really have?
Free diagnosis: we do the checking, not you
Send your exchange transaction export and one wallet address. We run the same tracing and reconciliation as in a paid engagement, and tell you what the data revealed. Free, no obligation to buy.
Two things, both easy
- Exchange transaction export (CSV) from every account, covering the full history. You get exchange-specific instructions for finding the export along with the diagnosis.
- One public wallet address per chain — preferably the one you withdrew to from the exchange. We don't need a wallet file, and we never need seed words or passwords.
- If you can't remember a single address, that's not a problem: they can be found from the transaction IDs on the withdrawal rows.
Three numbers and a price
Example figures. Your own figures come from your own data.
- Which wallets they are and how they were found
- Line-by-line breakdown of disposals with FIFO lots
- Tax consequence in euros, one tax year at a time
- The figures to enter in MyTax (OmaVero)
- Reconciliation to on-chain balances and a methodology statement
The diagnosis is work, not a form. That's why it tells you something you can't guess yourself, and why we only do a limited number at a time. The breakdown and calculation are the work you pay for in the reconstruction — the diagnosis tells you the size of the mess, the reconstruction its contents. If the numbers show you don't need us, we'll say so plainly and charge nothing.
Send your data for diagnosisHow your data is handled is described in the privacy notice. We never ask for a recovery phrase, keys or passwords.
Quick estimate in six questions
This estimate is based on what you remember — not on your data. It gives a price range and service level, but not what your history actually contains. The real transaction count is usually higher than the guess. That's what the diagnosis is for.
The questions that always come first
Will I have to pay a fine if I report past years now?
How many years back should I go?
Is swapping one crypto for another a taxable event?
What if I've only made a few sales?
Is this safe?
What we will never ask for: a recovery phrase, private key, password, exchange credentials or codes. A public address cannot be used to move your funds or to log in anywhere. If someone asks you for anything else, it isn't this service.
The exchange transaction export is a different matter — it contains personal data and is handled accordingly: encrypted connection, storage within the EU, no disclosure to third parties.
How do you handle my data?
Why shouldn't I just use tax calculation software?
What if the Tax Administration has already contacted me?
Let's find out how big the mess really is.
The diagnosis is free, and you get an answer within 24 hours of your request. Most people then know for the first time what they're dealing with — whether they buy the service or not.
