XBT Tax Helper: Fork & Mining Income
How the IRS sees it (US): under Rev. Rul. 2019-24, coins from a hard fork are ordinary income at their fair market value on the date you gained control of them (for example, when a wallet or exchange let you move them). That value also becomes your cost basis. Mined coins are income at fair market value when you receive them.
No price exists before September 1, 2026. XBT split from Bitcoin at block 961,632 (about August 8, 2026) but wasn't traded anywhere until September 1. How to value coins you controlled before then is a question for a tax professional.

- Koinly: import with the Universal CSV option. Each row carries its fair market value in the Net Worth column, so Koinly uses our price. Koinly may not know the BTCB2 ticker yet: when asked, map it to a custom asset.
- CoinTracker: create a custom currency named BTCB2 first, then import. CoinTracker's CSV has no value column, so set the price for each date by hand using the values above.
- Times are set to 00:00:00 UTC on each date. Adjust if you know the exact time.
Prices come from the xbt.live daily reference rate.
