Voluntary disclosure of taxes on cryptocurrencies

Forgetting to pay tax on cryptocurrencies? -> The path to impunity in Austria

The times when cryptocurrencies like Bitcoin or Ethereum could trade under the radar of tax authorities are definitively over. With the complete implementation of the EU directive DAC8 and the increased cooperation of international crypto exchanges with tax authorities, the probability of detection for undeclared profits has risen to a maximum in 2026.

Anyone who has failed to declare crypto gains, or has done so incompletely, in their income tax return in the past faces a significant financial and criminal risk. A timely and correctly executed tax voluntary disclosure In accordance with Section 29 of the Fiscal Offences Act (FinStrG), this is often the only way to prevent a penalty and legally regularize tax affairs.

Why the risk for crypto investors has increased massively in 2026

For a long time, the crypto sector was considered difficult to control. However, the legal framework in Austria has fundamentally tightened:

  • Automatic exchange of information (DAC8): Crypto service providers are now required to report their customers' transaction data directly to the tax authorities. The tax office often already has information on your holdings before you even submit your tax return.

  • Modernized financial analysis tools: The tax administration is increasingly using specialized software to track blockchain transactions and reconcile them with reported data.

  • Increased penalties: Deliberate tax evasion carries heavy fines and, in severe cases, prison sentences.

The voluntary disclosure as a „golden bridge“ back to legality

In Austria, the Fiscal Offences Act (FinStrG) offers an instrument with the voluntary disclosure which, when correctly applied, leads to complete impunity leads. For this to succeed, however, strict formal and substantive requirements must be met.

The requirements for an effective voluntary disclosure

  • Timeliness The report must be filed before the tax authority has already taken „substantial investigative steps.“ Once an audit has been announced or criminal proceedings have been initiated, it is generally too late for a self-disclosure granting immunity from prosecution.
  • Full disclosure: It is not enough to just provide vague information. All tax-relevant facts from recent years must be fully disclosed.
  • Statement of the misconduct: The voluntary disclosure must explicitly state which amounts were not taxed in which calendar years.
  • Payment of the tax liability: The shortened tax must actually be paid back within the period set by the authority.

Specific challenges with cryptocurrencies

The tax processing of crypto transactions differs significantly from traditional capital income. Particularly complex are:

  • Existing inventory vs. new inventory: The distinction between inventories before and after March 1, 2021, is essential for correct taxation.
  • DeFi, Staking & Lending: These activities often generate ongoing income, the valuation of which is barely possible at the time of receipt without technical assistance.
  • Data reconstruction: Many investors have not kept complete records over the years.
