1) Check for Missing Data
This could be due to missing data. Have you really connected all the wallets and exchanges you've traded with? Have you resolved the warnings in chain.report?
2) Address All Notices in Your Account First
If not, this could have significant tax implications against your favor. You can find more information in this article.
Please also note that the sum of your disposals (short-term) in the tax report represents your trading volume. This can, of course, be much higher than your capital, as it accumulates per disposal (e.g., through a trade). (These values are needed for entry in the tax form - instead of just the pure profit or loss)
3) Smart Contracts and Incorrect Prioritization:
There is a possibility that the token you wanted was not read, and another was prioritized. For example, LUNA instead of LUNC or vice versa. Solana instead of the desired Solcoin, etc...
Also, unsupported smart contracts can lead to faulty transactions, which can result in unexpected tax values. Here too, it's up to you to identify the relevant transactions - or tokens that generate an unexpected value due to prioritization.
4) Do You Think the Disposal Values Are Incorrect?
You can first click on the transaction details here. At the bottom, you'll see all disposals listed. If you click on the eye icon, you'll see each individual partial disposal.
Because: A sale can result in multiple disposals, as you may have acquired the asset in several purchases at different prices and times.
Without clicking on the eye icon, the average prices of all positions are displayed here.
Especially use these details if some acquisition prices are listed as 0 EUR here, you should definitely check 1) and 2) again. Otherwise, it's up to you: Check according to the FIFO method (First-In-First-Out) to what extent all acquisitions are correct. We only perform this check for our professional customers. Since the algorithm is thoroughly tested, we assume that the calculation of disposals is correct.
Have You Checked These Points and Still See an Error in chain.report?
Then we need a precise error description, where the error can be identified in specific transactions or other points. Information would include:
1) Which transaction(s) are involved? (Date, time, transaction type, token, amount, ...). Please provide a single example if possible.
2) Where do you see an error?
3) Can a screenshot clarify this?
4) Is there a suitable CSV file? If so, please upload it as well.
If you were able to identify the error so 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're not sure why?
Example: You can't resolve warnings?
Example: There are balance discrepancies in the wallets.
Please understand that we cannot perform a portfolio analysis for non-professional users to search for potential errors. This option is available for the professional package. A good starting point would be our FAQ - there you'll find answers to these three points and most other questions.
