So I exported all my Cointracker transactions and ran them through Koinly - it gives totally different answers for CGT liability! Over 100% difference for 2019/20 tax year which I have to report to HMRC on in 3 days. Makes me think that it’s all just jibberish, and ultimately is a black box that can spit out a vast range of different answers depending on tiny differences, and how much tax you end up paying is just a lottery! Has anyone else tried running their taxes through multiple platforms?
I wonder whether there are differences in their price feeds? Looking at a couple of big crypto-crypto transactions, the cost basis for the bought coin is 20% difference between the two. With rapidly fluctuating prices I guess the price feed really matters. Is it a daily average? Hourly? Or a down to the minute price?
