Do I need a separate Parkster app for Austria?

No. You can easily use the familiar Parkster app across borders in Germany and Austria.

Why are service fees in Austria subject to 19% VAT?

• Service fees: These are provided from Germany and are therefore subject to German tax law (19% VAT).
• Parking fees: The actual parking transactions in Austria are settled directly with the respective Austrian parking operator and the applicable VAT there.
