I knew that I couldn’t use the Koinly report at the Danish Tax Agency by itself. I used the data on the Koinly report to fill out the forms exactly as you recommended doing. We do it online. The trouble was that not all fields that I had to fill was accessible. I could add the income but the fields where I had to add my losses as well as capital gains weren’t there and I had to contact the Tax Agency in order to open them. They did, but due to the fact that I did it the very last day and then it was a weekend, I added the remaining data after the date due. That’s why they decided to control everything manually.
Long story short, they made their own calculation based on data from CSV files I provided them with. They said that if they needed more information, they would contact me. I expected that they would check if the data from the Koinly report was correct, but they didn’t. They just made their own calculations. They had, of course, those infamous “Missing purchase history” issues but didn’t ask me to send them additional information on the funds movement. They just added fictional “0” cost purchases and added all the balances to my income.
I don’t think that I have many import errors. I used tons of time to get rid of all those errors and my balance looks pretty good I believe.
They explain their refusal of using Koinly report like this (In Danish: Eftersom Koinly ikke behandler stablecoins og negative beholdninger efter gældende retspraksis er Koinly-rapporten tilsidesat.) which is translated to English as “Since Koinly does not process stablecoins and negative holdings according to current case law, the Koinly report is disregarded.”
I still need their explanation on what they mean by “processing stablecoins according to current case law”.
I downloaded another Koinly report - the full transaction history that shows all the movements that my money made during last year. Now I need compare the Tax Agency’s FIFO calculation with the Koinly’s and show them transactions that they missed in their report. That means I have to show the Tax Agency that they made their job badly.
Wish me luck.
