Austria Tax Residence and Foreign Income

Home or habitual presence

Unlimited liability can arise from a suitable dwelling used recurrently or habitual presence. After six months' presence it applies retrospectively. Citizenship is not decisive, and six months is not a universal tax-free allowance.

Worldwide income baseline

Ordinary unlimited liability generally includes domestic and foreign income. Applicable treaty allocations and relief must still be checked; a general liability rule does not determine the final bill.

Austrian income can remain taxable

Without Austrian residence or habitual presence, Austrian-source income such as employment or specified pensions can still create limited liability. Qualifying EU/EEA taxpayers may elect different treatment; the election has its own income conditions.

Employment can affect the start date

The guidance treats foreign employees with at least a six-month work permission or contract as unlimited taxpayers from arrival. Seasonal stays exceeding six months can also backdate liability. Border-worker treaty rules need separate assessment.
