Cost Basis Allocation

Cost basis allocation is the process of assigning a portion of the original asset's purchase price to a new asset acquired through a corporate action or a blockchain fork. When a hard fork occurs, the investor must determine how much of the original cost basis applies to the new token versus the legacy token.

This allocation is necessary to calculate capital gains or losses when either asset is eventually sold. Without a clear allocation, tax authorities might assign a zero cost basis to the new asset, resulting in higher capital gains taxes upon sale.

This method ensures that the investor does not overpay taxes by accounting for the value distribution between the two resulting chains. Proper documentation of this split is a standard requirement for tax reporting in many financial jurisdictions.

It requires precise historical data regarding the asset value at the time of the fork. Effective allocation mitigates the risk of double taxation on the same economic value.
