Bitcoin Abroad: Austria’s Self

Anyone who is tax-resident in Austria and sells bitcoin through a foreign crypto platform does not escape Austrian taxation by doing so. The decisive difference from many domestic providers lies rather in the fact that often no Austrian capital gains tax is withheld automatically.

Taxable bitcoin gains must then, as a matter of principle, be recorded by the investor personally through the income tax assessment. For private crypto income the special tax rate of 27.5 percent continues to apply in principle.

A foreign platform does not mean tax-free

Austria taxes income from cryptocurrencies as income from capital assets. This covers both certain ongoing income and realized increases in value. A taxable sale exists in particular where bitcoin is disposed of for euros or another legal currency. Using it to purchase goods or services can also constitute a realization.

• bitcoin bought for 20,000 euros
• later sold for 50,000 euros through a foreign platform
• taxable gain: 30,000 euros

At 27.5 percent this results in principle in a tax of 8,250 euros.

The fact that the platform is based outside Austria does not, in principle, change this calculation.

When does the exchange not take care of the tax?

Where a domestic crypto service provider is involved, an obligation to deduct capital gains tax applies to certain crypto income. The provider withholds the tax and remits it to the tax office. With a foreign platform, such an Austrian withholding agent is often absent.

The investor must then, in particular, do the following personally:

• determine the sale proceeds in euros,
• establish the acquisition costs for tax purposes,
• calculate gains and losses,
• record the taxable income in the assessment.

To the crypto tax tools comparison

Acquisition costs remain decisive

The tax is not levied on the entire sale proceeds but, in principle, on the gain. Where several purchases of bitcoin of the same kind have been made on the same relevant wallet or address, the moving average price applies in principle to new assets.

Particular care should therefore be taken in documenting:

• date of purchase,
• quantity of bitcoin purchased,
• acquisition costs in euros,
• fees,
• wallet transfers,
• earlier crypto-to-crypto exchanges.

Foreign platforms do not necessarily supply reporting that corresponds exactly to Austrian tax rules.

Losses must also be evidenced by the investor

An advantage of the assessment can arise where a bitcoin loss for tax purposes was realized on the foreign platform. Crypto losses can in principle be offset against certain other capital income. A loss offset across providers is not carried out automatically, however; it takes place through the income tax assessment. Reliable transaction data is particularly important for that.

Conclusion

Austrian investors must in principle pay tax on taxable bitcoin gains even where the sale takes place through a foreign crypto platform. The essential difference lies in the procedure: without an Austrian capital gains tax deduction, the investor regularly has to determine their taxable income themselves and declare it through the income tax assessment. The tax rate for private taxable crypto gains remains in principle 27.5 percent.
