Currently, digital assets investment becomes popular worldwide, including in Thailand. However, due to the unique nature of digital assets, the taxation relatedto digital assets remains unclear, especially in cases of “Hard Fork” or “Network Split”, which results in holders of digital assets on the original blockchain receiving a new type of digital asset in an amount equivalent to the original digital assets they hold. For example, if Mr. A owns 1 Bitcoin (BTC) and a Hard Fork occurs, Mr. A would then own 1 BTC and 1 Bitcoin Cash (BCH). The issue
is whether the owners of digital assets, who receive new coins from a Hard Fork, should be considered to have received an assessable income subject to income tax at the time they receive the new digital assets. This article proposes a clearer interpretation of the legal status and tax collection from receiving new digital assets under the Hard Fork process.
