Have a Foreign Bank Account? Then You Need to Know This!

Interest, dividends, or capital gains from abroad can be highly attractive – and profitable. But foreign accounts often hide a commonly underestimated tax trap that can lead to legal issues and costly back payments: Austria’s capital gains tax obligation.

A common misconception:

“My account is abroad – the tax office won’t find out.”
A dangerous assumption.

Because foreign-sourced capital income is taxable in Austria. Failing to declare or properly tax such income can result in severe consequences – from hefty tax reassessments to criminal proceedings for tax evasion.

Avoiding Double Taxation – But Do It Right

Yes, Austria has signed double taxation agreements (DTAs) with many countries. However:

  • These agreements only apply if your tax filings are done correctly.
  • A DTA does not replace proper tax compliance.

Mistakes are common – and costly. For example:

  • Capital income is declared incorrectly or too late
  • Foreign withholding tax is not properly credited
  • Austrian capital gains tax (KESt) is simply “overlooked”

We recommend:

  • Keep detailed records of all foreign payments and earnings
