A value becomes "0" when rounding occurs. This is often caused by a decimal point issue when data is exported from an exchange.

​Fix: Check whether spreadsheet software reformatted or rounded values in the file. If it did, upload the original exchange export again. If the original export itself contains zero or incorrectly rounded values, correct the source data before re-importing it.

More commonly, an acquisition is missing from the data you have imported into Recap. When our tax calculator recognises a disposal but cannot find a record of how the cryptocurrency was acquired, it uses a cost value of "0" and flags the error.

​Fix: We have a support article to help with missing acquisitions here.
