Austrian tax residency for expats: when it starts and what changes
Tax residency is the single decision point that reshapes an expat's finances. Before it, your home country's rules apply. After it, Austria generally taxes your worldwide income and capital gains — and the sequencing of the move itself often determines how much tax you pay in the transition year.
Key points at a glance
- You become Austrian tax resident through a residence (Wohnsitz) available for your use, or habitual abode of more than six months.
- Austrian tax residents are generally taxed on worldwide income and capital gains.
- Most investment income is taxed at a flat 27.5% (KESt).
- Double taxation treaties allocate taxing rights — they do not remove the obligation to declare.
- Actions taken before residency begins (realising gains, restructuring accounts) usually cannot be undone afterwards.
How Austrian tax residency is triggered
Austria applies two independent tests. The first is Wohnsitz: having a home in Austria that you can use and that indicates you will keep using it. Note that this does not require you to actually live there — an available apartment can be enough. The second is habitual abode (gewöhnlicher Aufenthalt), generally more than six months of presence, which applies retroactively from the start of the stay.
Meeting either test makes you subject to unlimited tax liability. If you keep a home in your old country as well, you may be resident in both, and the applicable double taxation treaty's tie-breaker rules decide which country is treated as your residence for treaty purposes: permanent home, then centre of vital interests, then habitual abode, then nationality.
Because the tests can be met partway through a year, the transition year is typically the most complex filing you will do — and the one most worth getting professional help with.
What Austria taxes once you are resident
Employment income is taxed progressively, with rates stepping from 0% through 20%, 30%, 40%, 48% and 50%, and 55% at the top. The 13th and 14th salary payments are taxed at a favourable 6% within limits.
Capital income — dividends, interest, and realised gains on securities — is generally taxed at a flat 27.5%. Austrian banks and brokers withhold this automatically; foreign brokers do not, so you self-declare.
Rental income from property abroad, foreign pension payments, and income from foreign business interests all need to be considered under the relevant treaty, which may exempt them in Austria (usually with progression) or grant a credit for foreign tax paid.
Fund reporting status: the detail with the biggest financial impact
Austria distinguishes between reporting funds (Meldefonds), which report tax figures to the Oesterreichische Kontrollbank, and non-reporting funds. Reporting funds are taxed on their reported deemed distributed income. Non-reporting funds face a lump-sum method that assumes a minimum taxable amount and is generally significantly more expensive.
This is why identical-looking global equity portfolios can produce very different net returns for two Austrian residents. It is also why US-domiciled ETFs, common in American and Canadian portfolios, are usually a poor fit once you are resident here.
Switching funds is itself a taxable event somewhere. Doing it before Austrian residency begins — in a jurisdiction where the gain is untaxed or lightly taxed — is often far cheaper than doing it afterwards.
Exit taxes, timing and the pre-arrival window
Some countries levy an exit tax when you cease residency; others tax gains realised in the year of departure at a favourable rate. Austria itself applies exit taxation on securities when unlimited tax liability ends, with an instalment option for EU/EEA moves.
The practical consequence is that the weeks before your move are usually your most valuable planning window: realising or resetting gains, closing or restructuring accounts, deciding when to trigger pension events, and choosing your arrival date all become harder or impossible once residency starts.
Reporting is now largely automatic. Under the Common Reporting Standard, foreign accounts are reported to the Austrian tax authority, so a plan that relies on non-declaration is not a plan.
Frequently asked questions
When do I become tax resident in Austria?
Either when you have a residence in Austria available for your use, or when your habitual abode exceeds roughly six months. The residence test can apply immediately on taking an apartment, while the habitual abode test applies retroactively from the start of your stay.
Does Austria tax worldwide income?
Yes. Austrian tax residents are subject to unlimited tax liability on worldwide income and capital gains, subject to relief under the applicable double taxation treaty, which may exempt certain income or grant a credit for foreign tax paid.
What is the capital gains tax rate in Austria?
Most investment income and realised securities gains are taxed at a flat 27.5% KESt. Bank interest is taxed at 25%. Austrian institutions withhold at source; income held with foreign brokers must be declared in your Austrian tax return.
Can I be tax resident in two countries at once?
Yes, under domestic law of both countries. The applicable double taxation treaty then applies tie-breaker rules — permanent home, centre of vital interests, habitual abode, then nationality — to decide which country is treated as your residence for treaty purposes.
