Foresight News: According to CoinDesk, the US Internal Revenue Service (IRS) has outlined new tax guidelines on how and when to tax cryptocurrency staking rewards. Crypto investors who receive rewards for validation activities on Proof of Stake (PoS) networks should include these rewards in their income for the year they control the tokens. The IRS states that the fair market value of the received validation rewards should be included in the taxpayer's total income for the tax year, and the value should be calculated from the moment the US taxpayer gains control of the tokens. This rule also applies to investors who stake tokens through cryptocurrency exchanges and receive additional units of cryptocurrency as rewards for validation.
