I need to adjust the cost basis for all holdings for the purposes of deemed deposition. I became a factual resident of Canada on xx date and therefore need to effectively “sell” and ‘re-acquire’ each of the holdings for the correct tax to be calculated moving forwards from that date. How can I accomplish this?
Add manual deposits for all of the assets on the day you became a resident, this will form your new cost-basis.
The other way you can do this is to create a second Koinly account, add the manual deposits for the day you became a resident, then lock your transactions and only import data from your wallets going forward.
