Austria is part of Schengen and as such Visa free travel for British Citizens is limited to 90 days in any 180 day period, This is a Schengen wide quota and so, for example a holiday in Spain would also count as part of this quota. Anybody wanting to stay longer than that must either apply for a Visa or a residency permit. Visas can only be obtained BEFORE travel at the Austrian Consulate in the country where you normally reside. In most cases this would be the Austrian Embassy in London
If you want to become resident in Austria, then you have to register within 3 days of taking up the accommodation This is commonly referred to as applying for a Meldezettel. In addition to this when leaving Austria you have to De-register; failure to do so could make you liable to a fine of over €700. EU Citizens who plan to stay longer than 3 months, need to apply for an "Anmeldebescheinigung"
Note ***:
Be very careful specifying a religion on the Meldezettel as Austria has a Church Tax for some denominations.
If you are here as a tourist in Austria, you may drive your vehicle for up to 12 months. If you move your main residence to Austria you may drive your vehicle for up to ONE month before you have to import it. Please also note that should you import the vehicle you will be liable to the NoVA tax which is based on the WLTP CO2 value of the vehicle.
Austrian Government Guidelines
If a child is born to an Article 50 holder in Austria, then an application must be made for an Article 50 family residency permit for the child within 90 days of the birth. A UK passport is required, but proof of application is enough to kick off the process. Failure to do so will mean the child is offered another residency permit which may be inferior to the Article 50 card.
For those with a 5 year article 50 card it is critical that you apply for the 10 year (permanent residency) card BEFORE your 5 year card expires. You will be entitled to apply as soo as you have had 5 years continuous residency. In general this would mean from the date you had a Meldezettel for Hauptwohnsitz, however a lack of an Anmeldebescheinigung, health insurance or an absence from Austria for more than 6 months may affect this date. Either way the renewal for the 5 year or 10 year card has to be applied for BEFORE it expires.
Holders of a British driving licence who have a main residence in Austria MUST change their UK driving licence within 6 months. This can be done without sitting a practicial test but a medical is required.
