Bitcoin Fraud: How the Austrian Tax Office determines losses
Fake investment platforms, phishing or so-called cryptocurrency advisers: Anyone who loses Bitcoin through fraud may face full losses from an economic perspective. However, in Austrian tax processing, this does not mean that the original acquisition costs can be automatically declared as a tax loss.
For cryptocurrencies held by individuals, the basic rules are as follows: Loss of coins due to fraud does not constitute a tax disposal. As a result, there is a lack of "realization events" that trigger capital losses for tax deductions.
Loss of 20,000 Euros--and no tax deduction?
Example:
- bought bitcoins for 20,000 euros;
- these coins were transferred to criminals due to fraud;
- subsequently received no compensation.
From an economic point of view, the loss amounted to EUR 20,000. But on the tax side, this € 20,000 held as a private asset cannot usually be simply used to offset stock gains, dividends or other cryptocurrency gains. The point is that the owner did not sell or exchange Bitcoin during the normal taxable disposal process.
Fraud, theft and hacking are handled in a similar manner
Austrian administrative practice roughly classifies the following situations into one category:
- stolen cryptocurrency;
- Loss due to fraud;
- Hacking;
- Loss of private key.
In a non-commercial context, any of the above circumstances occurring alone will typically not result in a tax-recognized realized loss. This makes fraud cases significantly different from voluntary sales at a price lower than the original purchase price.
Real loss sales are different
If someone buys Bitcoin for 20,000 euros and later sells it in the normal way for 12,000 euros, a tax loss of 8,000 euros is typically incurred. According to Austria's loss-deduction rules, the loss can be used to offset certain positive capital gains within the same year. If a person completely loses the same bitcoin through fraud, although they suffer the same financial losses, they usually lack the necessary "realization" conditions from a tax perspective.
Subsequent compensation may have new tax consequences
If the investor holds a right of recourse or a claim for damages, another level of tax issues may be involved. For example:
- Original acquisition cost: 15,000 euros;
- Bitcoin was lost due to fraud;
- Relevant responsible parties later paid damages of 18,000 euros.
In this case, compensation payments may become tax-relevant. Depending on the circumstances, it may realize previously unrealized gains or losses.
In any case, please fully document the fraud case
Even if no usable tax losses are initially incurred, investors should keep all evidence, including:
- wallet address;
- transaction ID;
- original purchase receipt;
- Records of chats and email exchanges;
- Police reports;
- Reports to regulators;
- Records of attempts to recover funds;
- Possible claims for damages.
These documentation will be particularly important if Bitcoin or funds are returned in the future.
The situation may vary for commercial assets
The restrictions described here mainly apply to cryptocurrencies held by individuals. If Bitcoin is a commercial asset, different profit determination and valuation rules apply. Therefore, business owners should assess the tax impact of their fraud losses individually.
Conclusion
Bitcoin losses caused by fraud are indeed real economic losses in Austria, but if the assets are held by individuals, they usually do not automatically translate into deductible tax capital losses. Fraud is not considered a normal disposal behavior. Only subsequent repayments or compensation payments may trigger a tax-significant event again.
