Importing from CoinLedger

Checked against app build 2026-08-26-01-41 on 2026-08-26.

How do I import a CoinLedger export?

Export your transaction history from CoinLedger as CSV, then open Import in the sidebar and choose the file.

Nothing is added until you have seen the preview, rows in the file, rows read, and the tax events they become, with every difference itemised. That contract is the same for every import, and the reconciliation count explains the arithmetic it prints.

Does CoinLedger’s tax calculation come across?

No, and that is deliberate. Only your transactions are imported.

The engine recomputes the tax under the UK matching rules with the rule named per disposal. If gains.tax reaches a different figure than CoinLedger did, the working paper shows exactly which rule produced each number, so the comparison is checkable rather than a coin toss between two black boxes.

Why must I import the whole history rather than one year?

Because section 104 pooling means your 2021 buys price your 2026 sells.

A partial history produces confidently wrong numbers, and the app would rather flag missing acquisitions than guess, see missing acquisitions and the UK rules.

What if a row looks wrong after the import?

Open it in Transactions, every row is editable.

The Undo control reverses a whole import in one step if the file was not the one you meant. Duplicates across overlapping exports are caught at preview time and explained in duplicates.
