After importing your transactions, you may find that you have some duplicated transactions in your account. While ZenLedger auto-detects and de-duplicates API imports and checks for most common duplications (such as the same wallet addresses) sometimes duplicates creep in when using custom CSVs or manual entries and then importing the source directly.

Additionally, some exchanges change things like decimal places and timestamps when reporting year over year. We try to catch these in the software, but inevitably duplicates can come up.

To prevent duplicate transactions, we recommend checking any custom or wallet/exchange CSV's before importing them to make sure the transactions you are going to import are not already imported into your account. You can do this by reviewing the transactions from that source that you have already imported.

Delete the duplicated file or API upload that contains the duplicate transactions. This is the best option when there are multiple transactions from the same source that should be deleted. Follow the steps below to delete a file or API you have already imported.

Step 1: Navigate to the Import tab at the top of your account.

Step 2: Click the three dots to the right of the import and select Delete from the drop-down menu.

Mark Ignore on the duplicated transactions in your Transactions list. This is best for when there are only a few duplicate transactions. Follow the steps below to mark a single transaction as Ignore if is a duplicate.

Step 1: Navigate to the Import tab at the top of your account.

Step 2: Find the duplicate transaction you wish to delete. You can use the filters at the top of this page to do so (e.g. filter by date and time, exchange, token, etc.).

Step 3: Click on the green drop-down arrow to right of the transaction and select Ignore. Marking a transaction as Ignore has the same effect as deleting it as it will no longer be included in your tax calculation.
