Everyone's situation is unique. The advice my tax guy gave me, was to only record a single tax event when selling the mined coins (for cash or another coin) and then do it with a $0 cost basis as opposed to record a tax event when receiving the coins from the pool and then again when selling the mined coin, using costs basis of what the coin was worth at the time it was mined.Does that site calculate taxes? Mining means you should be adding the coins gain acquired to your adjusted gross income, per the IRS, and on sale of the coins, that's a 2nd tax event.
