Has the IRS Issued Specific Guidance on the Taxation of Bitcoin or Ethereum Futures?

The IRS has not issued specific guidance exclusively for Bitcoin or Ethereum futures. However, since these futures are traded on regulated exchanges (like the CME), they are generally treated as regulated futures contracts (RFCs) under Section 1256.

This means the mark-to-market and 60/40 rules apply, based on existing law for RFCs.
