Austrian Bitcoin Sellers Must Declare Taxable Gains

Austrian taxpayers who sold Bitcoin without capital gains tax deducted may not be off the hook. While it's possible that no Austrian withholding agent was involved, this doesn't automatically make the sale tax-free. If no such agent was present, a taxable gain must generally be declared through the income tax assessment.

The special tax rate of 27.5 percent remains in effect, even if no capital gains tax was withheld. This can apply to sales through foreign crypto platforms or direct transactions without an Austrian withholding agent. For example, if you bought Bitcoin for €20,000 and sold it for €50,000, the taxable gain would be €30,000, subject to a 27.5 percent tax rate.

To calculate the gain, investors should secure records of purchase date, original acquisition cost, BTC amount, sale date, sale proceeds, fees, wallet transfers, earlier swaps, and platform transaction histories. Foreign crypto exchanges may not generate reports that match Austrian tax rules exactly, so it's essential to double-check these details.
