Summary
Hard forks create new tokens with tax implications. This guide explains income recognition, FMV tracking, and reporting for fork-derived cryptocurrencies.

- 2Recognize income timing: FMV when new tokens become accessible and tradeable.
- 3Track FMV determination: exchange price at first tradable date.
- 4Report as ordinary income: fork tokens not treated as capital gains at receipt.
- 5Set cost basis: FMV at receipt becomes basis for future disposals.
