Switzerland has a door that opens exactly once: the penalty-free voluntary disclosure. Report undeclared wealth and income yourself, for the first time, before any authority knows of it — and you pay back tax with late interest for up to ten years, but no fine and no criminal tax proceedings. The second time, that is gone: every further self-disclosure carries a fine, reduced but real. The door is generous, precise, and unrepeatable.
The conditions
Four things must align. First time: the penalty-free effect exists once per lifetime per person. Own initiative: the evasion must be unknown to any tax authority — disclosing after the office has asked is too late. Unreserved cooperation: complete disclosure of all undeclared elements, active support in the assessment. Serious effort to pay: the back tax plus interest must be settled — instalment arrangements are possible, refusal is not.
Completeness is the quiet trap: disclose the trading account but omit the staking income, and the effect of the entire disclosure is at risk. For crypto, complete means: all holdings for all years, all receipts at their CHF day value, all platforms and wallets — and, where relevant, an honest reckoning with the trader question, because the re-declared years will be read with the same eyes.
Austria forgives precise sequence, Canada prices the letterhead — Switzerland forgives exactly once. The question is not whether the door works. It is whether this moment deserves its only use.
What the disclosure costs — and what it does not
Payable: the evaded tax for up to ten years, plus late interest. Not payable: the fine (normally up to the tax itself, up to three times in serious cases) and the consequences of criminal proceedings. In crypto the bill is often milder than feared — if the years in question held private price gains, those were tax-free; what is owed is wealth tax and income tax on receipts, not the gains themselves. Which is exactly why reconstruction should come before fear.
The sequence
- Compute before deciding. Reconstruct all years and put a number on the actual back tax — in private constellations it is often surprisingly bearable.
- Completeness before speed. A disclosure that needs supplementing endangers the one-time effect. Better two weeks later and whole.
- Settle the trader question professionally, in advance. Re-declared years of high-frequency trading can shift the income side — that belongs priced into the disclosure, not sprung on it.
- File cantonally, organise payment. The canton of residence is competent; the ability to pay belongs settled before filing.
- Take the window seriously. "Unknown to the authorities" is a question of fact — and the data picture is changing. What is unknown today can be on file with the first exchange wave.
Whether the penalty-free effect applies turns on circumstances this page does not know. It frames the decision; it does not make it, and reading it creates no professional relationship.
