Your CoinTracking tax report shows warnings or unrealistic numbers? The cause lies in the crypto documentation, not the report. TX-Partner fixes the foundation.
Initial assessment of your CoinTracking data - 30 min.
A portfolio with DeFi usage. A missing bridge transaction in crypto documentation leads to incorrect cost basis in the tax report. The problem multiplies:
The tax report shows all taxable sales in the capital gains report. The "Show Warnings" button filters specifically those sales where errors occur – usually because cost basis is calculated as 0 EUR. Bottom right, CoinTracking sums the EUR value of all erroneous entries –with many errors, this amount can be substantial.
A faulty tax report is almost never a problem of the report itself. The cause lies in crypto documentation. TX-Partner encounters these scenarios most frequently.
Not all entries under "Missing Transactions" are linked or correctly classified. As long as deposits and withdrawals remain unpaired, CoinTracking lacks context. The result: missing cost basis and erroneous profit calculations in the report.
Transaction types are either incorrectly recognized by the tool or incorrectly set by the user. A trade as deposit, a transfer as sale – every misclassification distorts the tax report. Especially common with DeFi transactions and internal transfers.
When a sale chronologically precedes the corresponding purchase in the data, CoinTracking calculates with 0 EUR cost basis. Causes: missing or late-imported transactions, incorrect timestamps in manual entries, or gaps in import history. Result: fictitious profits in report.
CoinTracking calculates the tax report based on imported transactions. If errors exist there – missing imports, incorrect types, scam tokens – the report cannot be correct.

The Tax Report Is Only As Good As The Crypto Documentation. If the foundation is flawed, the report cannot be correct.
TX-Partner doesn't analyze the report, but the crypto documentation behind it. Missing imports are added, incorrect classifications corrected and scam tokens cleaned up. Only when the crypto documentation is correct can the tax report be generated accurately.
Correcting the report is pointless if the crypto documentation remains flawed.

In most cases, the cause is unlinked "Missing Transactions" or chronology errors. When CoinTracking cannot match a purchase to a position, it calculates with cost basis 0 EUR –and every sale becomes a fictitious full profit.
The three main causes are: Unlinked "Missing Transactions" (deposits/withdrawals without counterpart), incorrect transaction types (e.g., trade classified as deposit), and faulty chronological order (sale before corresponding purchase in the data). All three lead CoinTracking to calculate with incorrect cost basis.
