Please add the possibility to utilise 'deemed acquisition cost' in a single transaction when determining the profits/losses of the given transaction. https://discuss.koinly.io/t/support-for-deemed-acquisition-cost-for-a-transaction-finnish-tax-law/8355
Workaround
I need to apply the custom cost basis manually, using the "Capital Gains" report
  • Download "Capital Gains" report and open it in Excel
  • Add a column "Deemed cost" and calculate it as 20% of the value (proceeds)
  • Add a column "Deemed gain" and calculate it as proceeds - deemed_cost
  • Use the "deemed" values instead of the default columns whenever its more beneficial
  • I can also use DAYSBETWEEN formula to check if the asset was held over 10 years, then apply a 40% deemed acquisition cost
