"Date acquired" more recent than "Date sold" on Capital gains report

[chus1818]

Describe the problem:

The Capital Gains report for FY20/21 (UK) is showing transactions where Date Acquired is more recent than Date Sold even though all wallet balances are correct.

Which exchange/wallet is this regarding?

I have observed it with Kraken.

How did you import data into this wallet?

CSV imports of the ledger.csv file.

What have you tried to fix this so far?

Reimported CSVs and traced the issue on some example entries. For instance this day includes multiple entries with Date Sold before Date Acquired and appear on the Koinly UI as 3 regular spot BTC sales from coins with known cost basis (and purchased in the past):

Like OP, I am in the UK too and I have the same question. In fact, Koinly identifies negative holding periods as per the below transaction. Can you explain what this means and confirm that, for Capital Gains Tax purposes, this is correct please?

[Adrian_Mann]

That’s defiantly correct. It means that sale has been match with a purchases you made within 30 days. Just google “uk bed and breakfast tax rules” there are lots of websites that explain it regarding buying and selling shares and the rules apply to crypto in the exact same way.

Hi Adrian, got it. Makes sense. The implication is that this applies however the ‘asset’ has been acquired. In my example, the BETH acquired within 30 days of a disposal comes as a staking reward and not from an outright purchase. Thanks for the info.
