Tax Basis

Cost

Tax basis, within cryptocurrency, options, and derivatives, represents the original value of an asset for calculating capital gains or losses; this initial value incorporates acquisition costs, including brokerage fees and any direct expenses related to the purchase. Accurate determination of this basis is critical for proper tax reporting, particularly when dealing with complex transactions like staking rewards or airdrops, where the initial cost may not be immediately apparent. Subsequent adjustments to the tax basis occur through events like wash sales or constructive sales, impacting the realized gain or loss upon disposition.
