Austria offers what almost no jurisdiction on this site offers: statutory, complete immunity from penal consequences for fiscal offences — the Selbstanzeige under § 29 of the Fiscal Penal Code. Not discretion, not a negotiated outcome: meet the conditions and immunity follows. The price is precision. Self-disclosures routinely fail at three points — incompleteness, wrong timing, late payment — and a failed Selbstanzeige is a signed confession with nothing in return.
The three conditions
Description and full disclosure. The offence must be described and all material circumstances disclosed — completely enough that the authority can assess the tax without its own investigation. For crypto that means: every exchange, every wallet, every year, moving averages, receipts, euro values. A disclosure "in outline, details to follow" is not one.
Timeliness. Four blocking grounds end the window: prosecution steps already taken; the offence already discovered, and the discloser aware of it; for intentional offences, the start of an audit unless the disclosure is filed at the very beginning of the official act; and a previous Selbstanzeige for the same claim — there is no second attempt.
Payment. The shortfall must actually be paid within one month — for assessed taxes, from receipt of the assessment. A payment-plan application for up to two years is possible but must be made within the deadline. Partial payment buys only partial immunity.
The tactician's surcharge: 5 to 30 percent
File the Selbstanzeige only after an audit has been announced, and — for intent or gross negligence — immunity requires paying an additional surcharge: 5% of the shortfall, 15% above €33,000, 20% above €100,000, 30% above €250,000. The case law is strict: the mere announcement of the audit triggers the surcharge — a disclosure fully drafted but not yet filed does not count. Between "the auditor called" and "the disclosure is filed", hours can decide five- and six-figure amounts.
The statute rewards sequence, not remorse. The same disclosure is free, surcharged, or void — depending on which letter arrived first.
Why the window has a date
The most dangerous blocking ground for crypto is discovery — and DAC8 industrialises exactly that. Platforms have collected since January 2026; in 2027 the reports flow to the authorities, matched EU-wide. What would be a voluntary, surcharge-free Selbstanzeige today can be discovered — and therefore blocked — after the data reconciliation runs. The window closes not with a deadline but with a data delivery, whose date is known.
The sequence
- Reconstruct before you speak. All years, all platforms, old stock cleanly ring-fenced, staking on the Austrian rule. The disclosure must be complete the first time — there is no second.
- Have the blocking grounds assessed professionally. Whether a prosecution step exists or discovery must be assumed is legal judgement, not self-assessment.
- File through counsel — named persons included. Immunity works only for persons expressly named. Forgotten participants remain unprotected.
- Arrange the money before filing. The one-month deadline is unforgiving; financing belongs settled before the disclosure leaves the house — if need be with a timely instalment application.
- After an audit announcement: count hours. Filing before the audit begins saves the immunity but costs the surcharge. From here every minute belongs to a defence practitioner, not a form.
If it was only a mistake
Not every correction needs fiscal-penal law. Errors made without fault, or with slight negligence, are often fixed by a simple corrected return. Drawing that line — correction or Selbstanzeige, negligence or intent — is itself an advisory question, and writing the wrong label into a filing is one of the ways a small matter becomes a large one.
Whether a Selbstanzeige works turns on circumstances this page does not know. It frames the decision; it does not make it, and reading it creates no professional relationship.
