This is how you check your acquisition values and disposals.
November 12, 2026
1) Look for missing data
This can in particular be due to missing data. Have you really connected all wallets and exchanges with which you have traded? Have you resolved the warnings in chain.report?
2) First resolve all notices in your account
If not, this can turn out significantly to your disadvantage for tax purposes. You can find more information on this in this article.
Please also note that the sum of your disposals (in short) in the tax report represents, for example, your trading volume. This can of course be significantly higher than your capital, since it is added up for each disposal (e.g. through a trade). (These values are needed for entry in the tax form - instead of the pure gain or loss)
3) Smart contracts and incorrect prioritization:
It is possible that the token you wanted was not read and another one was prioritized. For example, LUNA instead of LUNC or vice versa. Solana instead of the desired Solcoin, and so on...
Unsupported smart contracts can also lead to broken transactions that can cause the tax burden to reach unexpected values. Here, too, it is up to you to track down the corresponding transactions - or tokens that produce an unexpected value because of the prioritization.
4) You believe that the disposal values are not correct?
Here you can first click into the transaction details. Here you see all disposals listed at the bottom. If you click on the eye, you see each individual partial disposal.
This is because a sale can result in several disposals, since you may also have acquired the asset in several purchases at different prices and points in time.
Without a click on the eye, the average prices of all positions are displayed here.
In particular, use these details if some acquisition prices are listed here at 0 EUR; you should definitely check 1) and 2) again. Otherwise it is up to you here: Feel free to check, according to the FIFO method (First-In-First-Out), to what extent the acquisitions are all correct. Otherwise we only carry out this check for our Professional customers. Since the algorithm has been tested very thoroughly, we assume that the calculation of disposals is correct.
You have checked these points and you still see an error in chain.report?
Then we need a precise error description in which the error can be identified on specific transactions or other points. Information would include, for example:
1) Which transaction(s) are involved? (date, time, transaction type, token, amount, ...). Please give a single example if possible.
2) Where do you see an error?
3) Can a screenshot illustrate this?
4) Is there a suitable CSV file? Then please upload this as well.
If you were able to identify the error this clearly, please send us the data via the support chat on the website.
If you cannot clearly identify the error or its cause:
Example: The tax burden is too high, but you do not know exactly why?
Example: You cannot resolve warnings?
Example: There are balance discrepancies in the wallets.
Please understand here that we cannot take on a portfolio analysis for Non-Professional-User here in order to look for potential errors. This option exists for the Professional package. A good starting point would be our FAQ - there you will find answers to these three points and to most other questions.
