To calculate your charitable contribution deduction when you donate virtual currency, you need to determine the fair market value (FMV) of the virtual currency at the time of the donation. The specific calculation depends on how long you have held the virtual currency:
For example, if you donate virtual currency that you have held for more than one year and its FMV at the time of donation is $10,000, your deduction would be $10,000. If you have held the virtual currency for one year or less, and your basis in the virtual currency is $8,000 while its FMV at the time of donation is $10,000, your deduction would be limited to $8,000.
Additionally, if the value of the donated virtual currency exceeds $5,000, you are required to obtain a qualified appraisal to substantiate the deduction. The value reported on a cryptocurrency exchange cannot be used in place of a qualified appraisal. Failure to obtain a qualified appraisal will result in the disallowance of the deduction, even if the value is readily ascertainable from an exchange.
