A crypto accounting with multiple exchanges and DeFi usage. Missing imports from previous years lead to a chain reaction in the tax report:
The 3 Most Common Causes of "Missing History"
Blockpit shows "Missing History" when import data is missing for the period before the first recorded transaction. TX-Partner sees these scenarios most frequently.
Fehlende Exchange-Imports
Older exchange accounts were not connected. Coins came from an exchange that is not imported. Especially for platforms that are no longer actively used, years of transaction history are often missing.
Missing Data Sources
Exchanges and wallets that were not imported into Blockpit are completely missing from the crypto accounting. Particularly common: older exchange accounts, wallets on other chains, or platforms that were only briefly used. Blockpit sees the incoming transaction but not the source.
Manual Entries & Auto-Balancing
Users often try to fill gaps with manual entries or use Blockpit's "Auto-Balancing" function. Both methods create transactions with a cost basis of 0 EUR. The problem is visually solved, but the tax error remains: every sale is calculated as a full gain.
Missing History = Incorrect Tax Calculation
Crypto tax tools calculate based on imported transactions. If the crypto accounting has gaps, Blockpit sets the cost basis to 0 euros and every sale is treated as a gain.

If the transaction history has gaps, Blockpit calculates with a cost basis of 0 EUR and the tax calculation becomes incorrect.
