Anyone living abroad who owns a property in Austria that is rented out will sooner or later face the question of where the rental income has to be taxed. The answer is rarely straightforward: it depends on the country of residence, the relevant double taxation treaty, and the type of property involved. These questions often only surface—particularly in cases of inheritance, second homes, or capital investments in Vienna, Salzburg or Tyrol—once the first tax return is due.

Anyone in this situation should have the purchase contract, lease agreements, proof of tax residence and, if available, previous tax assessments ready. Simon Immobilien helps classify the property correctly and, where needed, puts clients in touch with tax advisors and notaries, but does not replace tax or legal advice for individual cases.

The essentials at a glance

1. Rental income from an Austrian property is generally subject to limited tax liability in Austria, regardless of the landlord’s place of residence.
2. An existing double taxation treaty between Austria and the country of residence determines which state has the right to tax the income and how double taxation is avoided.
3. For the rental of immovable property, the OECD Model Convention generally assigns the taxing right to the state where the property is located—in this case, Austria.
4. Foreign landlords must apply for an Austrian tax number and file an income tax return in Austria as soon as taxable income arises.
5. The country of residence may take the Austrian income into account when calculating the personal tax rate, even if it exempts that income from its own tax.
6. Without clean documentation of rental income, deductible expenses and depreciation, unnecessary tax burdens or back payments frequently arise.

Why the question of tax liability is so often underestimated

Many owners living abroad initially assume that rental income from an Austrian flat is taxed in their country of residence—after all, that is where they live, where they pay the rest of their income tax, and where their centre of life is. In most cases, this assumption is wrong. The Austrian Income Tax Act provides for limited tax liability for people without a residence or habitual abode in Austria, and this limited liability covers, among other things, income from letting and leasing domestic immovable property. What matters, therefore, is not where the owner lives, but where the property is located.

This situation is relevant to a growing group: German, Swiss or Italian investors who have invested in Vienna or in the tourist regions of western and southern Austria; heirs who take over a property from an estate while continuing to live abroad; and people who have moved abroad for professional reasons but keep and rent out their Austrian flat. In all these cases the same basic rule applies, even though the practical details vary. Anyone looking into Simon Immobilien’s current property listings beforehand should factor in this tax dimension from the outset, not only after the purchase.

Basic concepts you should know

Limited versus unlimited tax liability

Unlimited tax liability applies to people with a residence or habitual abode in Austria and covers their entire worldwide income. Limited tax liability applies to people without such a connection to Austria and covers only certain domestic income items listed in the law—including income from letting and leasing domestic property. So anyone who owns only a rented flat in Austria, with no other connection to the country, is subject to limited tax liability and must declare that income here.

What a double taxation treaty does

A double taxation treaty (DTT) is an agreement between two states that determines which state has the right to tax in cross-border situations where both states would in principle have a claim. Austria has concluded such treaties with a large number of countries, largely based on the OECD Model Convention. For income from immovable property, Article 6 of this model provides that the right to tax lies with the state in which the property is located. This means that even if the landlord lives in Germany, Switzerland or another treaty state, Austria is entitled to tax the rental income from a property located here.

Exemption or credit

To prevent the same income from being taxed twice in full, DTTs generally provide for one of two methods. Under the exemption method, the country of residence exempts the Austrian income from its own tax, but often still takes it into account via a so-called progression clause when determining the tax rate applicable to the remaining income. Under the credit method, the country of residence generally taxes the income as well, but credits the tax already paid in Austria. Which method applies depends on the specific treaty and must be examined case by case—blanket statements are risky here.

What actually matters for practical classification

Several factors are decisive for the tax treatment of a specific case and must be examined individually before any reliable conclusion can be drawn.

• The landlord’s state of tax residence and whether a DTT exists with Austria.
• The type of letting: permanent residential letting, letting as a second home, short-term tourist letting, or commercial use—each category can be treated differently for tax purposes.
• The legal form in which the property is held: private individual, company or foundation lead to different taxation rules.
• The amount of rental income and deductible expenses, such as interest, maintenance, depreciation and management costs.
• Any permanent establishment or permanent representative in Austria, which can trigger further tax obligations.
• Reporting obligations to the Austrian tax office and, where applicable, in the country of residence.

These points should not be considered in isolation, as they influence one another. One example: short-term tourist letting via platforms may, under certain circumstances, be classified in Austria as a commercial activity rather than classic letting, which brings different VAT consequences. Anyone wanting information on the location and rental market of a particular region will find initial guidance in the location guides for towns in the region, which helps in assessing the type of letting involved.

An overview of typical charges that regularly become relevant for Austrian properties in this context helps with classification:

Charge / item	Amount or nature	Note
Income tax on rental income	progressive, per income tax scale	limited tax liability, annual return
Real estate transfer tax on purchase	3.5% of the purchase price	fixed by law (GrEStG)
Land register entry fee	1.1% of the purchase price	fixed by law
VAT on letting	generally VAT-exempt without input tax deduction, opting possible	depends on type of use
Real estate capital gains tax on sale	flat 30% on the capital gain	fixed by law, with exceptions

Step by step: how foreign landlords should proceed

The path from the first letting to ongoing tax compliance can broadly be broken down into the following steps.

1. Clarify the state of tax residence and check whether a DTT exists with that state—ideally with tax advice, usually taking a few days to two weeks.
2. Apply for an Austrian tax number with the relevant tax office if one does not already exist, usually via Finanzamt Österreich, taking a few weeks.
3. Classify the type of letting together with a tax advisor or property manager, particularly in the case of short-term tourist letting.
4. Keep ongoing documentation of rental income, operating costs, interest and depreciation throughout the year, ideally digitally and continuously.
5. File the annual income tax return in Austria, generally by 30 June of the following year if represented by a tax advisor, otherwise earlier.
6. Take the Austrian income into account in the tax return of the country of residence according to the method provided there, usually as part of the annual return that is due anyway.
7. When selling the property: check the real estate capital gains tax and the self-assessment carried out by the notary or lawyer handling the contract.

A worked example for orientation

To illustrate this, here is a simplified example that is intended purely as a rough guide and does not replace an individual tax calculation. An heir living in Germany permanently rents out a condominium in Salzburg and generates annual rental income of €14,000. After deducting expenses such as depreciation, interest and management costs of an assumed €5,000, a taxable surplus of €9,000 remains. This amount is subject to Austrian income tax under the progressive tax scale; for persons with limited tax liability, a statutory surcharge is added to the tax base for the purpose of calculating the tax rate before that rate is applied. In Germany, depending on the applicable DTT provisions, this amount would be exempt from German income tax but would be taken into account when determining the tax rate applicable to the rest of the German income.

In a second scenario, an investor living in Switzerland lets a flat in Vienna short-term via a booking platform, generating annual income of €22,000 against deductible expenses of €9,000. Here, the question of VAT treatment and possible classification as a commercial activity also arises, which can change the tax base and reporting obligations. Both examples show that without concrete figures from the individual case and without examining the relevant DTT, no reliable tax burden can be stated—the figures given serve solely to illustrate the calculation logic.

Common mistakes and how to avoid them

Foreign landlords often underestimate their Austrian tax liability because they assume they are adequately covered in their country of residence. This leads to late or entirely omitted tax returns in Austria and, subsequently, to back payments plus late-filing surcharges.

Another common mistake is not having an Austrian tax number even though rental income is already flowing—without this number it is neither possible to file a correct return nor to properly document any credit claimed in the country of residence.

Confusing gross rent with the taxable surplus is also widespread: deductible expenses such as interest, depreciation, maintenance and management costs are often not fully captured, which results in an unnecessarily high tax burden.

In the case of short-term letting, classification as a commercial activity is frequently overlooked, which brings VAT consequences and other reporting obligations. And finally, the sale of a property is often considered in isolation, without taking into account that the real estate capital gains tax and possible DTT provisions on the capital gain require their own separate examination, distinct from the ongoing taxation of rental income.

Checklist: tax liability as a foreign landlord in Austria

• Identify the country of tax residence and whether a DTT exists with Austria.
• Check whether an Austrian tax number already exists; if not, apply for one.
• Clearly classify the type of letting: permanent, tourist, or commercial.
• Document all rental income and deductible expenses on an ongoing, traceable basis.
• Note the deadlines for the Austrian income tax return in your calendar.
• Clarify the treatment in the country of residence together with a local tax advisor.
• If a sale is planned, check the real estate capital gains tax and DTT aspects early.
• Involve a notary and tax advisor as fixed points of contact for the Austrian side.

Frequently asked questions

Do I have to pay tax in Austria at all as a foreign landlord?

Yes, generally you do. Income from renting out an Austrian property is subject to limited tax liability in Austria regardless of the owner’s place of residence. This applies even if tax is already being paid on total income in the country of residence.

What happens if there is no double taxation treaty?

Without a DTT, there is no treaty-based arrangement to avoid double taxation between Austria and the relevant state. In such cases, it depends on the domestic rules of the country of residence whether and how tax already paid in Austria is credited. This situation should definitely be clarified with tax advice in the country of residence.

Do I need my own bank account or tax number in Austria?

A tax number from the Austrian tax office is required as soon as taxable rental income is generated. An Austrian bank account is not strictly required, but in practice it significantly simplifies the handling of payments and refunds.

Does anything special apply to short-term letting via platforms?

Short-term tourist letting can be treated differently for income tax and VAT purposes than classic permanent residential letting. Depending on scope and organisation, it may even be classified as a commercial activity, which can trigger additional reporting and tax obligations.

Does selling the property affect the ongoing taxation of rental income?

The sale is generally treated separately from ongoing letting and is subject in Austria to real estate capital gains tax on the sale proceeds. Here too, it must be checked how the relevant DTT allocates the capital gain between Austria and the country of residence.
