Tax residence
One dwelling kept and used, or a stay of more than six months — either makes you an Austrian tax resident with worldwide tax liability. Here is how the tests work, and how the 70-day rule can keep a holiday home out of them.
In short
- You are Austrian tax resident once you have a domicile here — a dwelling kept and used — or your habitual abode.
- Legal title is irrelevant: an owned flat, a rented flat, a holiday home or a permanently available hotel room can each be a domicile.
- A stay of more than six months makes you resident irrefutably, whatever your intentions — and the liability is backdated to the first day of the stay.
- The secondary-residence ordinance protects a dwelling used no more than 70 days a year — but only if your centre of vital interests has been abroad for over five years and you actually keep a day list.
- If two countries both claim you, the treaty tie-breaker decides — permanent home first, then centre of vital interests.
Why residence is the decisive question
Residence is the switch that turns on worldwide taxation. A resident pays Austrian income tax on everything — salary and business profits at progressive rates of up to 55%, most investment income at a flat 27.5% — wherever in the world it arises. A non-resident pays Austrian tax only on certain Austrian-source income. Nationality, visas and residence permits play no part in the test: a person can hold an Austrian passport and be a non-resident, or hold no permit at all and be fully tax resident.
Austrian law uses two alternative tests, and meeting either one is enough. The first is the domicile (Wohnsitz); the second is the habitual abode (gewöhnlicher Aufenthalt). A finance-ministry ordinance adds a third element — a carve-out that can neutralise a secondary residence. All three are summarised below and explained in the sections that follow; where residence sits in the wider system is mapped on the overview of Austrian tax for new residents.
| Test | Threshold | Effect |
|---|---|---|
| Domicile (Wohnsitz) | A dwelling kept and used — no minimum number of days | Residence for as long as the dwelling is at your disposal |
| Habitual abode (gewöhnlicher Aufenthalt) | A stay of more than six months, not necessarily in one calendar year | Residence — irrefutable once the six months are exceeded, and backdated to the start of the stay |
| Secondary-residence ordinance | Centre of vital interests abroad for more than five calendar years, use of the dwelling on at most 70 days a year, and a day list actually kept | The dwelling does not count as a domicile for income tax purposes in that year |
Domicile: a dwelling kept and used
A domicile exists where you have a dwelling under circumstances suggesting you intend to keep and use it for more than a passing moment. The dwelling must consist of one or more rooms furnished for regular living — but who owns them is beside the point. What counts is the factual possibility of using the place, not the legal title. A rented flat qualifies as readily as an owned one; so does a family holiday chalet, and so can a hotel room that is kept permanently at your disposal.
Two features of the test surprise many newcomers. First, there is no day-count in it at all: a dwelling you keep available can create residence even in a year you barely visit, subject only to the 70-day ordinance described below. Second, you can have several domiciles at once, in Austria and elsewhere — which is precisely how double residence conflicts arise and why the treaty tie-breaker rules exist.
Registration with the municipal authority — the Meldezettel every new arrival must file within three days, as described in the first-weeks checklist for living in Austria — is an indication of a domicile, but no more than that. Failing to register does not prevent a domicile from existing, and registering does not by itself create one. The tax test looks at the facts of the dwelling, not the paperwork.
Habitual abode — and the 183-day myth
The second route into residence is the habitual abode: staying in Austria under circumstances suggesting the stay is not merely temporary. The law adds a bright line — a stay of more than six months leads irrefutably to a habitual abode. No intention, arrangement or paperwork can argue it away, and the six months need not fall within one calendar year; once the line is crossed, the unlimited liability is backdated to the first day of the stay. Presence anywhere in Austria counts; the test is national, not tied to one town or dwelling. Genuinely separate visits for holidays or family reasons are not added together, and mere transit stops do not count — but temporary absences abroad do not interrupt a stay, and several shorter stays are added together where an intention to continue the stay in Austria is apparent.
This is where the popular "183-day rule" needs correcting. It is true in one direction: stay beyond roughly half a year and you are resident, full stop. It is false in the other: staying fewer than 183 days does not keep you safe, because a domicile — a dwelling kept and used — makes you resident from the first day it is available, with no day-count at all. Anyone planning around days alone, while keeping a flat in Vienna, has misunderstood the system.
Unlike domiciles, of which you can have several, Austrian law allows only one habitual abode at a time for domestic purposes. Treaties define the term slightly differently, which is why, at treaty level, a person can have a habitual abode in two states — one of the reasons the tie-breaker chain exists.
The 70-day rule for secondary residences
Because a mere holiday home can be a domicile, the Minister of Finance issued an ordinance for people whose lives are genuinely elsewhere. Under it, an Austrian dwelling does not count as a domicile for income tax purposes in a given year if three conditions are all met:
- your centre of vital interests — the country your personal and economic life is closest to — has been outside Austria for more than five calendar years;
- the Austrian dwelling (all Austrian dwellings taken together) is actually used on no more than 70 calendar days in the year; and
- you keep a list of the days of use — a genuine, contemporaneous record.
Two qualifications matter before the arithmetic. The ordinance switches off the domicile only for income tax purposes; the dwelling remains a domicile under the general tax code for everything else. And for someone who has only just moved out, the ministry accepts that the switch to limited tax liability takes effect from the start of the following calendar year, rather than only once five years have passed — but if the centre of vital interests returns to Austria inside that period the condition fails, and the protection is lost for the years in between.
The day count is strict: in practice any day on which the dwelling is used counts in full, however short the visit, though days spent in Austrian hotels do not count against the dwelling's 70. That is no way round the limit — hotel nights and other Austrian stays still count towards the six-month habitual-abode test, and a pattern of rented apartments and hotel stays alongside the 70 days invites the tax office to find a habitual abode all the same. Someone who owns a ski flat in Kitzbühel, spends five winter weeks and a summer fortnight there and documents every day can remain a non-resident with only limited Austrian tax liability.
Married couples need particular care. Each spouse counts their own days and keeps their own list — but the ordinance adds a harder rule: if your spouse or registered partner is an Austrian resident taxpayer and you are not permanently separated, your use of their Austrian dwelling gives you a domicile and unlimited liability outright, whatever your own day count. The ordinance helps only couples who have both moved their lives abroad.
No day list, no protection. If the record is not kept — through oversight as easily as intent — the ordinance simply does not apply. The dwelling then counts as a domicile for income tax, and its owner becomes an Austrian tax resident with worldwide tax liability, potentially for years already past.
When two countries both claim you: the treaty tie-breaker
Domestic tests in two countries can easily both be satisfied — a family home abroad, a flat in Vienna. Where a double taxation treaty exists, a cascade of tie-breaker rules assigns you to one state for treaty purposes. The chain is worked through in order, stopping at the first rule that produces an answer:
Permanent home
You are treated as resident of the state in which you have a permanent home available to you. If only one state has one, the question ends here.
Centre of vital interests
With homes in both states, residence follows the state to which your personal and economic relations are closer — family, social, cultural and religious ties on one hand, sources of income on the other. Under Austrian case law, personal relations, and family ties above all, take priority over economic ones in case of doubt.
Habitual abode
If the centre of vital interests cannot be determined, or you have a permanent home in neither state, the state where you habitually stay decides. At treaty level a person can have a habitual abode in both states, so the chain may continue.
Nationality
Failing that, you are treated as resident of the state of which you are a national.
Mutual agreement
If you are a national of both states or of neither, the two tax administrations settle the question by mutual agreement.
Losing the tie-break does not erase Austrian residence under domestic law — filing obligations can remain — but it confines Austria to the taxing rights the treaty leaves it. How treaties allocate those rights, and what happens without a treaty, is explained on the page on Austria's double taxation treaties.
Fixing the date your residence begins
For a planned relocation, the start of residence should be a chosen date, not an accident. Until the day a dwelling is at your disposal or a long stay begins, you are outside the worldwide net — free to restructure companies, review trusts and realise gains under the rules of your departure country. From that day, you are inside it, though with one important cushion: financial instruments, derivatives and crypto assets are stepped up to fair market value at entry, so pre-move appreciation stays out of the Austrian tax base — provided the values at the moving date are documented.
Practically, that means settling the commencement date deliberately, obtaining valuations of the portfolio for that date, and completing any restructuring first. The pre-immigration planning page lists what to review, and the relocation timeline puts the steps in order. The mirror image — giving up residence, and the 70-day trap for those who keep their Vienna flat — is covered on the page about the tax consequences of leaving Austria.
Questions on this page
Does owning a holiday home in Austria make me tax resident?
Not automatically. If your centre of vital interests has been abroad for more than five years, you use the home no more than 70 days a year and you keep a list of those days, it does not count as a domicile for income tax. Without the day list, it does.
Is registering with the municipality the same as tax residence?
No. The Meldezettel registration is a public-law duty and at most an indication. Tax residence depends on a dwelling kept and used, or on a stay of more than six months — with or without registration.
Do repeated short stays add up to the six months?
Not if they are genuinely separate visits for holidays or family reasons. But temporary absences abroad do not interrupt a stay, and several shorter stays are added together where an intention to continue the stay is apparent. The six months need not fall within a single calendar year — and once they are exceeded, the liability is backdated to the first day of the stay.
Can I be tax resident in Austria and another country at the same time?
Yes, under the two countries' domestic laws. Where a double taxation treaty applies, its tie-breaker assigns you to one state for treaty purposes — usually the state of your permanent home and closest personal ties.
Do both spouses have to keep the 70-day list?
Each spouse counts their own days and keeps their own list. But the ordinance goes further: if one spouse is an Austrian resident taxpayer and the couple is not permanently separated, the other spouse's use of that Austrian dwelling creates a domicile and unlimited liability outright, whatever their own day count. The ordinance helps only couples who have both moved their lives abroad.
