Bitcoin Exit Tax in Austria: Which Value Counts?

Emigrating from Austria With Bitcoin: Which Value Counts for Tax

Anyone leaving Austria and taking sizeable Bitcoin holdings along does not have to sell first for a tax question to arise. If Austria loses its right to tax a later Bitcoin gain because of the departure, the so-called exit tax, or deemed disposal taxation, can apply.

For tax purposes the calculation is then made, in principle, as if the Bitcoin concerned had been sold at the moment of departure. The deemed sale proceeds are the fair value, that is in principle the market value, at that moment.

What Counts Is Not the Original Purchase Price on the Day of Departure

Suppose an investor bought Bitcoin for €20,000. At the point of departure from Austria that is decisive for tax, the coins are worth €70,000.

In simplified terms this gives:

• acquisition cost: €20,000
• market value on departure: €70,000
• increase in value accrued up to departure: €50,000

For exit taxation it is in principle this increase in value, accrued up to the loss of the Austrian taxing right, that is considered. For taxable new crypto assets the special tax rate of 27.5 percent applies in principle. Cryptocurrencies are expressly among the assets covered by the Austrian deemed disposal rules.

Which Day Determines the Bitcoin Price?

It is not necessarily the day of the flight, the deregistration or the change of home that decides.

What matters in principle is the moment at which Austria loses its right to tax a later disposal gain. That can happen in particular through a change of tax residence. Double taxation treaties regularly assign the right to tax disposal gains to the state of residence.

For Bitcoin investors it is therefore important to document the relevant moment cleanly. That includes in particular the holding, the acquisition costs and a verifiable Bitcoin market value on that date.

Moving Within the EU or the EEA: Tax Can Be Deferred

Where a private individual departs to an EU or EEA state, an important relief is available.

In the Austrian tax return it is in principle possible to apply for the tax arising from the departure not to be assessed for the time being. Taxation is thereby regularly deferred until a later triggering event, in particular an actual disposal.

That means: even though the increase in value is in principle determined at departure, the tax does not necessarily have to be paid immediately in the case of a privileged EU or EEA departure.

Departure to a Third Country Can Look Different

If, on the other hand, the investor moves to a state outside the EU and EEA area, non-assessment under this rule is in principle not available.

The departure can then lead to the increase in value accrued up to that point being captured for tax immediately. The Austrian finance ministry explains this principle for departures to the United Kingdom after Brexit, for example: because the EU and EEA conditions are no longer met, the increase in value is in principle taxable at once.

With large Bitcoin holdings in particular, the choice of the new country of residence can therefore have a considerable effect on liquidity.

Stricter Proof Obligations Have Applied Since July 2026

Austria tightened its exit taxation in 2026.

For new non-assessments decided after 30 June 2026, a recurring obligation to provide proof applies to larger amounts. Where the income determined on departure, or on a comparable transfer, totals more than €100,000, it must regularly be demonstrated that no event has yet occurred that would trigger the later assessment of the tax.

According to the legislative materials, suitable account, custody or comparable confirmations can serve as proof. With cryptocurrencies, verifiable wallet and transaction documentation will be correspondingly important in practice.

Where a prescribed recurring proof obligation is not met, this can itself trigger the assessment of the tax previously not assessed.

A Later Fall in Price Can Become Relevant

Exit taxation is in principle intended to capture the increase in value that arose while the Austrian taxing right applied.

Where non-assessment has been applied for and a sale follows later, the further development in value can therefore also become relevant. The Austrian income tax guidelines contain examples in which, where the later sale price is lower, the increase in value present at the time of departure is not in every case taxed unchanged.

The actual calculation, however, depends on how the departure was structured and on the later disposal.

What Applies to Legacy Bitcoin Holdings?

A departure should be examined with particular care where the Bitcoin was acquired up to and including 28 February 2021.

Such coins count in principle as legacy holdings and do not automatically fall under the Austrian crypto tax regime in force since 2022. Whether a taxable hidden reserve actually exists on departure therefore also depends on whether a later sale would have been taxable in Austria at all.

For new assets acquired after 28 February 2021 the situation is clearer: realised gains in value fall in principle under the modern crypto tax regime at 27.5 percent.

These Records Should Be Secured Before Departure

Anyone emigrating from Austria with larger Bitcoin holdings should document the following in particular before changing tax residence:

• Bitcoin quantity at the relevant moment
• all wallets and exchange accounts
• original acquisition costs
• date of acquisition
• legacy or new holding status
• Bitcoin market value on departure
• the price source used
• earlier crypto-to-crypto swaps
• transaction histories and wallet addresses
• later sales after the departure

For an application for non-assessment in particular, this documentation can still be relevant years after the move itself.

Conclusion

Anyone emigrating from Austria with Bitcoin should not keep an eye on the later sale alone. If Austria loses its taxing right because of the departure, the departure itself can already be treated for tax like a deemed disposal.

What is decisive in principle is the market value of the Bitcoin at the moment Austria loses its taxing right.

On departure to an EU or EEA state, non-assessment of the tax can be applied for until a later realisation event. Since July 2026, additional recurring proof obligations apply to non-assessment amounts with income of more than €100,000.

On departure to a third country, by contrast, the tax can in principle already fall due on departure. With Bitcoin holdings that have risen sharply in particular, the tax treatment should therefore be clarified before the change of residence.
