Errors and warnings

What does a CoinTracking negative-balance warning mean?

Last reviewed: August 15, 2026
A negative balance in CoinTracking means: at the time of the sale or outflow, not enough of that asset had been imported. The tax-report warning is the symptom. Typical causes are a missing purchase year, a wallet that is not connected, a purchase booked as a deposit, or an unmatched transfer. CoinTracking still calculates — often with cost basis zero and a gain that is too high.

How do you translate the warning into a data problem?

Do not look at the report button. Look at the asset, wallet and date of the first negative point. Immediately before that, an inflow is missing. That is the same gap chain.report shows as a balance discrepancy.

Which causes are most common?

A CSV only for the current year, depot splits in CoinTracking, a transfer to a hardware wallet that was never imported, a DeFi outflow without a counterpart, duplicate tickers without a contract address. The software is rarely “broken”. The history is incomplete.

How you close the gap

1) Import the same history into chain.report. 2) Open the wallet and asset with the gap in CleanUp. 3) Reload the missing exchange, an older CSV or the counterpart wallet. 4) Generate the report only after the balance closes.

Frequently asked questions

Can I ignore the warning if the amount is small?

No. A small negative balance often flips an entire lot to cost basis zero. The gain then jumps far above the economic result.

Does it help to reset the CoinTracking balance to zero by hand?

That hides the gap. The tax office will still ask for the origin. Reload the missing movement instead.

Can I keep using the CoinTracking export?

Yes, as one source. You still have to reload the years, wallets and chains that trigger the warning.
