You now have the option to sell 39 of your X coins in order to cover your tax bill leaving you with 81 coins (Or you can pay it another way and keep your coins) Now this is all on the assumption that the price of the coin stays still….. but this is crypto and we know that doesnt happen. What happens if in the last month the price of X coin drops to only $50 per coin…..now all the sudden you will need to sell 78 of your X coins in order to cover the tax bill, which leaves you with only 42 coins valued at 50 dollars each which leaves you with a total profit of $2,100. You can see all the sudden that $12,000 worth of coins you earned isnt all that attractive any more after this mess, now there is a little hail Mary here so read on. By selling 78 of your coins at $50 you actually incurred a capital loss, because when you received the coins they had a base value of $100 each. Selling 78 at $50 has essentially incurred a $3,900 capital loss which can be used to offset the tax obligations on a capital gain from something else. Its worth noting, you cant use this capital loss against the interest you earned, as the interest earned is considered income tax not capital gains tax, these are taxed differently, so you will still have to pay that same income tax bill. However if you made a nice $10,000 capital gain on something else that you sold, you could use that $3,900 capital loss against that capital gain which means you would only need to declare a capital gain of $6,100. If that gain was not subject to any CGT discounts then this also gets added to your taxable income, which will come with a further $1,982 onto your tax bill, based on the 32.5 cents to the dollar bracket. If you had to declare the entire 10k as a gain, then it would have been a tax bill of $3,250, so you essentially saved $1,268 in tax by taking a capital loss of $3,900 on your X coin sale. Your still at a net loss of $2,632 + your $3,900 tax bill from your interest earned from staking, which is a total cost of $6,532 from your original $12,000 you thought you made from “staking”.
