Learn More About the Documentation StandardTax reports are only as good as the underlying crypto documentation. TX-Partner analyzes the root cause behind every error message.
CSV imports from different exchanges overlap, duplicates creep in. CoinTracking cannot automatically determine which data is correct.
Wrong timestamps, typos in amounts, swapped exchange names – manual entries are error-prone and lead to incorrect results.
Exchange APIs are often incomplete. Old transactions are missing, DeFi swaps are not exported. What the API doesn't deliver won't appear in CoinTracking either.
CoinTracking classifies transactions automatically, but is often wrong. A "transfer" is classified as a "trade". This massively distorts the tax burden.
