Works Deliveries under Austrian VAT Law

Foreign plant construction companies looking to do business in Austria must understand the concept of “works delivery.” This article explains what works deliveries are and how they are treated under Austrian VAT law. It offers practical insights – from registration requirements to the role of a fiscal representative in Austria (Fiskalvertreter in Österreich) – to provide real value for international businesses.
Works deliveries are not everyday transactions; they are complex operations combining elements of goods supply and services. Especially in the international plant engineering sector, this leads to numerous tax questions: Where is the turnover taxed? How should invoices be issued correctly? What obligations arise vis-à-vis the tax authorities? Mistakes in classification can result in double taxation or penalties. The following sections provide a structured overview – from the definition to the tax treatment to hands-on implementation tips – so that foreign entrepreneurs can carry out their projects in Austria confidently and successfully.
Definition of a Works Delivery
In simple terms, a works delivery is a supply contract mit Montage (with installation) – the supplier not only delivers goods but also installs or processes them at the customer’s site. Austrian law (speziell § 3 Abs. 4 UStG) provides a precise definition: A works delivery occurs when a business accepts an order to work on or process an item provided by the customer and uses its own principal materials in doing so. In other words, the client contributes something (e.g. a machine, a building, or a component) and the supplier substantially incorporates materials of its own into that work.
Crucially, the materials supplied by the contractor must be more than mere ancillary items (like minor ingredients or supplies); they form the core of the finished work. Works deliveries in plant construction typically involve delivering major plant components combined with on-site installation at the customer’s facility. A classic example is installing a control cabinet, custom-built for the client’s production line, directly into the existing system. Because it becomes permanently integrated with the client’s equipment, it is clearly not a simple goods delivery but a single performance comprising both a supply and a service.
This concept is distinct from a work performance (Werkleistung). In a work performance, the contractor also performs work for the client but uses no significant materials of their own – the primary materials are provided by the client. For VAT purposes, a work performance is treated as a service, not a goods delivery. This distinction affects the place of supply and the VAT treatment, which the next section examines in detail.
Likewise, a works delivery must be distinguished from a pure goods delivery without installation. If a foreign company simply delivers equipment to the customer’s door without any on-site assembly or processing, it constitutes an ordinary supply of goods. In such cases, the standard VAT rules for cross-border trade apply: For a delivery to an Austrian business, the transaction can be handled as an intra-Community supply (0% VAT), whereas for a delivery from a non-EU country, import VAT is paid by the importer. Only when delivery and installation are combined does the transaction become a distinct works delivery for tax purposes.
VAT Treatment of Works Deliveries
The VAT treatment of a works delivery depends largely on the place of supply. Under EU VAT rules (Directive 2006/112/EC) and Austrian law, for supplies of goods with installation the place of supply is defined as the place where the installation actually takes place. Thus, if the assembly occurs in Austria, the entire works delivery is subject to Austrian VAT, regardless of where the supplier is established or where the goods originate. For foreign entrepreneurs in plant construction, this means they must address Austrian VAT requirements for projects performed in Austria.
Reverse charge mechanism: In many cases, Austria applies the reverse charge mechanism when a foreign entrepreneur performs a works delivery. Reverse charge means the VAT liability shifts to the recipient of the service. Specifically, if a non-established business carries out a taxable works delivery in Austria for a taxable business or legal entity, then the Austrian recipient must self-assess the VAT. The foreign supplier issues its invoice without Austrian VAT, explicitly noting that the “tax liability of the recipient” applies (for example, by indicating “Reverse Charge”) and stating the Austrian customer’s VAT identification number.
The reverse charge system spares foreign companies from having to register for VAT in Austria for one-off projects – at least as long as their service is provided to a taxable business in Austria. The situation is different for B2C: If a foreign supplier provides a works delivery to a private individual or non-business entity in Austria, reverse charge does not apply. In that case, the foreign supplier must charge Austrian VAT (currently 20% standard rate) on the invoice and remit it to the Austrian tax authorities.
It is important to correctly classify the transaction as a works delivery to avoid mistakenly treating parts of it as VAT-free intra-Community supplies. As soon as on-site installation in Austria is part of the deal, the entire performance is considered carried out in Austria. Foreign suppliers should therefore not, for example, zero-rate the goods portion as an intra-EU supply and only separately tax the installation. Instead, the transaction is treated uniformly as a works delivery taxable in Austria. Misclassification can lead to tax reassessments and issues in the event of an audit. Additionally, the foreign supplier should not mistakenly charge its domestic VAT on the project – since the place of supply is Austria, the transaction is taxable only in Austria (either via the customer under reverse charge or via the supplier’s own VAT registration in Austria).
VAT Registration Requirements for Foreign Businesses
Whenever a foreign entrepreneur conducts taxable activities in Austria, the question of VAT registration arises. In the case of works deliveries, thanks to reverse charge a supplier with no establishment in Austria usually does not need to register for VAT in B2B situations. However, as soon as a works delivery is provided to a non-business recipient in Austria (e.g. a private customer), registration in Austria becomes mandatory. The company must notify the Austrian tax office and obtain an Austrian VAT identification number (UID) in order to properly report and remit the VAT.
In practice, B2C scenarios in plant construction are rare, since large installations are typically ordered by businesses. But if a private client or an organization not entitled to input tax credit in Austria is to receive a delivered-and-installed project, the foreign supplier cannot avoid a VAT registration. From the very first euro of turnover in Austria (unlike domestic small businesses, foreign firms have no sales threshold exemption here), a VAT number must be obtained. The Austrian small business regime (annual turnover up to €55,000 exempt) generally does not apply to businesses without an establishment in Austria. Even if the volumes are small, foreign providers of taxable works deliveries must complete a normal VAT registration.
One special consideration: if a foreign supplier brings goods into Austria or purchases goods locally for use in the project. Even if the main contract with an Austrian business falls under reverse charge, intra-Community movements of goods or imports into Austria can trigger a registration obligation. For example, a German contractor transports its own parts to Austria to install at the client’s site. If this transfer of goods is treated as an intra-Community supply to Austria, the foreign business in principle would have to account for an intra-Community acquisition in Austria – which requires having an Austrian VAT number. In such cases, it’s advisable to involve a tax expert or representative who can assist with planning (e.g. choosing the right delivery method or import arrangements). In some situations, the Austrian client can take on the import of the goods, sparing the foreign supplier from needing to register. These scenarios illustrate that questions of registration around works deliveries should be clarified in advance with professional advice.
Role of the Fiscal Representative in Austria
For foreign companies that face VAT obligations in Austria, the fiscal representative in Austria plays a crucial role. A fiscal representative is a tax agent based in Austria who acts on behalf of the foreign company. Particularly for companies established outside the EU, appointing a fiscal representative is mandatory in order to obtain a VAT registration. However, even EU-based businesses without a permanent establishment in Austria often voluntarily use a fiscal representative to minimize risks and outsource the administrative burden.
The tasks of a fiscal representative in Austria include, among others:
- VAT registration: They apply for the Austrian VAT number (UID) for the foreign company and set up all necessary filings with the tax authorities.
- Ongoing bookkeeping and filings: The fiscal rep ensures that all periodic VAT returns (UVA) are submitted on time (monthly or quarterly depending on turnover) and that tax payments are made promptly. They also prepare annual returns and EC Sales Lists (if required).
- Communication with authorities: As a local contact, the fiscal rep handles correspondence with the Austrian tax office and other public agencies, for example in case of inquiries or audits.
- Advice and compliance: A good fiscal representative in Austria also advises the company regarding optimal VAT structuring. They explain the application of the reverse charge mechanism, review invoices for Austrian requirements, and help avoid mistakes (such as incorrect tax rates or missing mandatory information).
By engaging a fiscal representative, a foreign plant builder ensures that all local tax obligations are properly fulfilled. Especially for large plant-construction projects with high values, this provides peace of mind: all VAT amounts are handled correctly, deadlines aren’t missed, and the company can focus on its core business. The term “fiscal representative in Austria” thus represents a key partner who builds the bridge between the foreign company and the Austrian tax authority.
Not least, a fiscal representative also helps overcome language and administrative barriers, since all formalities with the Austrian authorities are conducted in German.
Typical Case Examples from Plant Construction
To illustrate how things work in practice, here are some example scenarios showing the VAT handling of works deliveries in plant construction under various circumstances:
- Example 1: German plant builder with an Austrian business client (B2B) – A German machinery company delivers and installs a production line at an Austrian manufacturing plant. The place of supply is Austria, so a taxable works delivery is taking place in Austria. However, the Austrian customer is a VAT-registered business with a VAT ID. Therefore, the reverse charge mechanism applies. The German supplier invoices the project net (with no Austrian VAT) and notes “Reverse Charge – VAT to be accounted by recipient” along with the customer’s VAT number on the invoice. In this scenario, the German company does not need to register in Austria. The Austrian business owes the VAT and can typically claim it simultaneously as input tax.
- Example 2: US plant builder with an Austrian business client (B2B) – A company from the USA installs new equipment in an Austrian facility. Although the supplier is based outside the EU, the VAT treatment is no different from the previous example: If the Austrian client is a business or legal entity, reverse charge applies. The US firm therefore issues an invoice with no VAT, and the Austrian client assumes the tax liability. An important consideration here is the import of goods: since the machinery components are shipped from outside the EU, it should be decided in advance who will handle the import and pay the import VAT. Often the Austrian customer acts as the importer, as they can deduct the import VAT as input tax. This way, the US supplier doesn’t have to deal with the import tax. The US company would only need an Austrian VAT registration if it also made other taxable supplies in Austria without reverse charge or if it wanted to reclaim Austrian input tax.
- Example 3: Swiss plant builder with a private customer in Austria (B2C) – A Swiss company delivers and installs an automatic gate system at an Austrian private residence. Here, the place of supply is Austria, which means Austrian VAT is due. Unlike in the B2B cases, the Swiss contractor cannot use reverse charge because the recipient is not a business. Consequently, the Swiss company must register for VAT in Austria in advance and appoint a fiscal representative in Austria. The invoice to the customer is issued with 20% Austrian VAT. The Swiss company must report and remit this tax to the Austrian tax office (usually via its fiscal rep). While the Swiss business can claim any Austrian input VAT incurred (e.g. on material purchases or customs) in its returns, the administrative burden is significant. This example shows that serving private clients in Austria requires careful tax planning from the outset. (Note: If the supplier in this scenario were an EU company, it would also need to register, though it would not be legally required to appoint a fiscal representative. Many EU businesses still choose to use a fiscal rep in Austria to simplify the process.)
- Example 4: Pure installation service without supplying materials – A Polish assembly team erects a production line in Austria using all main components provided by the Austrian client. In this case, there is no works delivery but rather a work performance (service), since the Polish company is not contributing significant materials of its own. The place of supply for this installation service is also Austria (the location where the work is physically carried out). For VAT purposes, the reverse charge mechanism applies here as well in the B2B scenario: the Austrian business customer is liable for the VAT, while the Polish service provider can invoice without VAT. The Polish company does not need to register in Austria, provided it engages in no other taxable activities in Austria.
The examples demonstrate that whether a foreign supplier faces VAT obligations in Austria for a works delivery depends chiefly on the customer’s status (business or private) and on how the movement of goods is handled. In many B2B cases, the reverse charge mechanism relieves the foreign contractor from having to pay VAT in Austria. In other situations, however, a thorough knowledge of the rules and timely fulfillment of obligations are indispensable to avoid problems.
In summary, it becomes clear that foreign entrepreneurs need solid tax planning for works deliveries in Austria. The use of the reverse charge mechanism in most B2B cases does simplify proceedings, but all formalities must still be strictly observed. When in doubt, it is recommended to seek expert advice early to avoid later tax reassessments and penalties.
Practical Implementation and Tips
Finally, here are some practical tips on how foreign plant builders can successfully and compliantly execute works deliveries in Austria:
- Define scope and determine place of supply: Clearly specify in your contract which services (delivery, installation, etc.) you will provide, as this influences the VAT treatment. Analyze at the start of each project whether a works delivery in the VAT sense is present and whether the place of supply will be Austria. If an installation in Austria is part of the deal, plan from the beginning with Austrian VAT rules in mind.
- Confirm customer status (B2B vs B2C): Determine whether your Austrian customer is a business (with a VAT ID) or a private customer. The tax handling will follow accordingly: For B2B, be sure to obtain the customer’s VAT ID and apply the reverse charge mechanism. For B2C, budget additional time for the VAT registration process.
- Apply for VAT registration early: If a registration in Austria is required, take care of it well in advance. Obtaining a VAT number can take a few weeks. Prepare all necessary documentation (e.g. proof of company registration, power of attorney for the fiscal rep, a description of your activities in Austria).
- Engage a fiscal representative in Austria: For non-EU businesses, a fiscal rep is mandatory. But EU businesses should also consider hiring a fiscal representative in Austria. This representative will assist with registration, handle communication with the tax office, and ensure all deadlines and obligations are met.
- Issue invoices correctly: Draw up your invoices according to Austrian requirements. Under reverse charge, no VAT amount should be shown; instead, note the reason (“Reverse Charge”) and include the customer’s VAT number. For invoices where Austrian VAT is charged, your own Austrian VAT number must appear on the invoice, and the tax rate must be clearly indicated. In all cases, ensure all required information is present (names and addresses of both parties, date of supply, consideration, etc.) so as not to jeopardize the customer’s input tax credit. Apply the same principles to any advance or installment invoices: under reverse charge, do not show any VAT (but do note what the advance payment is for); if you are liable for the tax, include Austrian VAT on the advance invoice and remit it accordingly.
- Maintain records and fulfill reporting duties: Keep detailed records of the sales made in Austria and any input VAT incurred. Submit all required filings (VAT returns, annual return, and if applicable EC Sales Lists or Intrastat declarations for goods movement). Omissions can lead to substantial penalties.
- Seek expert advice: International VAT law is complex. Do not hesitate to consult an Austrian tax advisor or your fiscal representative for guidance. This helps you avoid tax traps – for example, misjudging a transaction as tax-exempt – and ensures your project is set up correctly from the start.
- Consider VAT refunds: If you do not have your own VAT registration in Austria due to reverse charge, you can still reclaim any Austrian VAT you have paid. EU companies use their home country’s electronic VAT refund portal, while non-EU companies can file a refund claim under the 13th Directive. Have your fiscal rep assist with this to meet all deadlines and formalities.
By following these measures, foreign companies can carry out their
works deliveries in Austria
smoothly. The combination of good planning, knowledge of the regulations, and professional support (through a fiscal representative in Austria) ensures both customer satisfaction and compliance with the tax authorities.
