Austria

Austria introduced a comprehensive crypto tax reform effective 1 March 2022, bringing cryptocurrency fully within the scope of the Austrian capital income tax (Kapitalertragsteuer, KESt) framework. The reform was notable for two things: the flat 27.5% rate applied uniformly to all crypto gains regardless of holding period, and the introduction of automatic withholding by Austrian-registered exchanges — mirroring the treatment of traditional securities. The Austrian Federal Ministry of Finance (BMF) has issued accompanying guidance covering the reform's scope, the treatment of DeFi activity, and the distinction between new-regime and legacy assets. The framework is administratively clean for domestic exchange users and more complex for DeFi and foreign exchange activity.

Core Tax Treatment

Cryptocurrency gains are subject to a flat 27.5% KeSt on net disposal gains for assets acquired on or after 1 March 2021. There is no holding period exemption — an asset held for five years is taxed at the same rate as one held for five days. The 27.5% rate is final: it does not stack on top of income tax and is not subject to progression. Losses from crypto disposals may offset gains from other capital income (dividends, bond interest, traditional securities) in the same year — a notably generous provision compared to many jurisdictions that ring-fence crypto losses.

Austrian exchanges registered under the Depotgesetz automatically withhold and remit KeSt on taxable disposals, in the same way a broker would withhold tax on share sales. For investors trading exclusively on domestic registered exchanges, the compliance burden is effectively zero — the tax is handled at source.

The Post-2021 Asset Divide

The 1 March 2021 cut-off date creates a significant divide in the portfolio. Assets acquired before 1 March 2021 are treated as legacy assets (Altvermögen) and retain the prior tax treatment: gains are tax-free if the asset was held for more than one year. Short-term gains on legacy assets (held less than one year from date of acquisition) are taxable as other income at the individual's marginal rate. This distinction requires per-asset acquisition date tracking — legacy and new-regime assets in the same portfolio are taxed differently.

Automatic Withholding by Austrian Exchanges

Austrian-registered exchanges implement automatic KeSt withholding — the same system used for traditional securities. When a taxable disposal occurs, the exchange withholds 27.5% on the net gain and remits it to the tax authority. The investor receives the net proceeds and receives an annual tax statement (Jahresabrechnung) showing withholding amounts, usable to complete the annual E1 return. This makes domestic exchange use administratively simple; the primary compliance exposure arises from DeFi activity, foreign exchange use, and staking income, none of which benefit from automatic withholding.

Crypto-to-Crypto

Crypto-to-crypto swaps are taxable disposals under the Austrian post-2021 framework. Exchanging one cryptocurrency for another triggers a gain or loss calculation on the disposed asset at its euro market value at the time of the swap. The acquired asset takes on a new acquisition cost equal to the market value at the time of receipt. This applies to DEX trades and DeFi swaps equally — the absence of a registered Austrian intermediary does not remove the tax obligation, it merely removes the automatic withholding mechanism.

Staking and Income Events

Staking rewards are taxable as capital income at 27.5% at the point of receipt, assessed at the euro market value when tokens are received. The same applies to lending interest and DeFi yield. Mining income is treated as business income and taxed at the individual's marginal income tax rate rather than the 27.5% KeSt rate — a distinction that matters for high-volume miners. Once received, staking tokens are new-regime assets with their own acquisition date.

Legacy Assets

For investors who held cryptocurrency before 1 March 2021 and have not yet disposed of it, the legacy asset status remains intact regardless of how long the asset is subsequently held. A Bitcoin acquired in 2018 remains a legacy asset and its disposal gains are tax-free as long as the one-year holding requirement from the original acquisition date was met — which for any asset still held in 2026 it certainly has been. This makes long-term legacy holders in a uniquely advantageous position within the Austrian system.

Reporting

For domestic exchange users, the annual Jahresabrechnung from the exchange provides the basis for the E1 income tax return. DeFi activity, foreign exchange gains, and staking income must be manually declared in Annexe E1a. Austria is an EU member state and DAC8 exchange reporting has been active from 2026.
