Austrian Tax Authorities Disallow Scams and Theft as Deductible Capital Losses

Under Austrian tax regulations, privately held Bitcoin lost to fraud, phishing, theft, or lost private keys cannot be automatically claimed as a deductible capital loss. According to tax practice guidelines, losing digital assets to criminal activity does not constitute an official realization event, which is required to offset acquisition costs against other capital income.

In standard scenarios, an investor who sells cryptocurrency at a price below the purchase cost realizes a tax-recognized capital loss that can offset taxable capital gains within the same tax year. In contrast, losing cryptocurrency through fraudulent schemes leaves the investor with an economic loss of the initial purchase amount, but without the taxable disposal event needed to claim the deduction.

The guidance notes that subsequent financial restitution can create tax implications. If a victim receives damages or compensation from a liable party at a later stage, that payment may trigger a realization event, potentially generating taxable gains or deductible losses depending on the compensation amount relative to the original acquisition costs.
