- For payouts, I just use MiningPoolHubStats (using MiningPoolHub and Nicehash as my pools) earnings report to roughly get my payouts.
- For electric, I just took what I normally paid monthly before mining and subtract that from the total after mining, and just used that amount. I can't track how much electric I'm consuming on a 220v line, but I use a Kill-a-watt on my 110v outlet to get an idea for that one.
- Track every receipt for mining expenses.
- I then used bitcoin.tax and provide this information to my CPA/tax guy and he handles the rest for me.
