The rules behind the numbers.
27.5% flat rate
KESt applies to dividends, interest, fund income and realised capital gains. There is no reduced rate for long holding periods.
Reporting vs. non-reporting funds
Reporting funds (Meldefonds) are taxed on actual and deemed distributed income each year. Non-reporting funds face a punitive lump-sum assessment — the single most expensive mistake expats make with a foreign broker.
Cost basis increases
Income already taxed during the holding period is added to your cost basis, so it is not taxed twice when you sell. The calculator applies this automatically.
Austrian vs. foreign broker
An Austrian custodian deducts KESt at source (steuereinfach). With a foreign broker you must declare everything yourself in your annual tax return.
