A foreign company can operate in Poland without incorporating a Polish subsidiary, yet its people, premises, equipment, warehouse, project or agent may create a Polish tax presence. The first control is to separate two questions: a fixed establishment for VAT and a permanent establishment for corporate income tax. They have different legal sources, functions and consequences, so one result does not automatically determine the other.
1. Begin with two separate tax tests
VAT fixed establishment determines, among other matters, where particular services are supplied and who accounts for VAT. CIT permanent establishment determines whether and to what extent Poland may tax business profits of a non-resident enterprise. A company may have one without the other, and both analyses can change when operations, contracts or authority change.
| Question | VAT fixed establishment | CIT permanent establishment |
|---|---|---|
| Main source | EU VAT Directive and Implementing Regulation 282/2011, applied with Polish VAT law | Polish CIT Act plus the applicable tax treaty and any MLI modification |
| Core test | sufficient permanence and suitable human and technical resources for the relevant receiving or supplying function | fixed place, qualifying construction/installation activity or dependent-agent test under the applicable rule |
| Main consequence | place of supply, invoice/reverse charge, person liable and reporting | Polish taxing right over profits attributable to the PE |
| Registration or subsidiary | evidence only; not sufficient by itself | evidence only; treaty and actual activity control |
2. What creates a VAT fixed establishment?
For services covered by Article 44 of the VAT Directive, Article 11(1) of Regulation 282/2011 requires a structure other than the business establishment, with sufficient permanence and suitable human and technical resources to receive and use services for its own needs. Ownership is not always required, but the foreign company must have the relevant resources at its disposal in a manner comparable to its own resources. A VAT identification number alone is expressly insufficient.
- Human resources: employees or other personnel actually available to perform the relevant function.
- Technical resources: premises, systems, machinery or other infrastructure suited to that function.
- Permanence: more than an occasional or transitory arrangement.
- Capability: the structure must be able to receive and use, or where the relevant rule requires, provide the services concerned.
- Connection: the particular supply must be directed to or involve that structure; the company-wide label is not enough.
3. Receiving services, supplying services and intervening are different functions
The same phrase fixed establishment is used for different VAT functions. Article 11(1) focuses on a customer's capacity to receive and use services. Article 11(2) focuses on capacity to provide services, including for Article 192a. Article 53 then asks whether a local establishment actually intervenes in a taxable supply. Administrative support such as accounting, invoicing or debt collection alone is not intervention under that rule.
| Transaction question | Evidence to review |
|---|---|
| Which establishment receives the service? | nature and use of service, contract, order, customer VAT number, payer |
| Can Polish resources receive and use it? | personnel, systems, premises, access and decision rights |
| Does a Polish establishment supply or intervene? | resources used before or during performance of the taxable supply |
| Is the role only administrative? | accounting, invoicing and debt collection do not alone establish intervention |
| Can the recipient location be identified? | if not, Article 22 may allow the supplier to rely on the customer's business establishment |
4. What the CJEU says about subsidiaries and outsourced resources
The Court of Justice consistently requires economic and commercial reality, not a corporate shortcut. A subsidiary or exclusive service provider can be relevant only when the substantive resource test is met. The supplier is not expected to reconstruct the customer's group contracts without indicators, and the same resources generally cannot both supply the service and constitute the recipient's structure for receiving that same service.
| Case | Practical point |
|---|---|
| Dong Yang, C-547/18 | a subsidiary does not automatically create its foreign parent's fixed establishment; the supplier is not required to examine parent-subsidiary contracts |
| Titanium, C-931/19 | property let without the owner's own staff performing the letting-related services was not a fixed establishment in those facts |
| Berlin Chemie, C-333/20 | group status and exclusive services were insufficient; access comparable to own resources and distinct receiving capacity matter |
| Cabot Plastics, C-232/22 | exclusive toll manufacturing and ancillary services did not by themselves create the customer's fixed establishment |
| Adient, C-533/22 | group or service contract alone is insufficient; resources must be distinct from those used to supply the services and not merely preparatory or auxiliary |
5. VAT consequences: place of supply, invoice and reverse charge
A fixed-establishment conclusion must be linked to the specific transaction. For general B2B services, a service supplied to and used by a Polish fixed establishment may be located in Poland. Whether the foreign supplier charges Polish VAT, the customer applies reverse charge, or a local establishment is treated as intervening requires a separate person-liable analysis. The existence of an FE does not make every purchase or sale Polish-taxable.
- Classify the supply and confirm whether the general B2B rule or a special place-of-supply rule applies.
- Identify the contracting customer and the establishment actually receiving and using the service.
- Test Polish human and technical resources and their permanence.
- Determine whether a Polish establishment intervenes in the outgoing supply.
- Set the correct VAT number, invoice wording, reverse-charge treatment and JPK/VAT reporting.
- Recheck deduction or refund route and correct past invoices if the conclusion changes.
6. CIT permanent establishment: domestic law is only the first layer
Article 4a(11) of the Polish CIT Act defines a foreign permanent establishment as a fixed place through which a foreign entity carries on all or part of its business, a construction, assembly or installation activity, or a person acting for the enterprise with and habitually exercising authority to conclude contracts. The provision expressly defers to a tax treaty where it states otherwise. Always read the treaty applicable to the enterprise's residence and check whether MLI changes it.
| Layer | Control |
|---|---|
| Polish CIT Act | domestic definition and limited tax liability |
| Bilateral tax treaty | Article 5 wording, exclusions, construction threshold and agent rule |
| MLI / synthetic text | whether both states' positions modify the particular treaty |
| Actual facts | place at disposal, duration, activity, personnel, authority and contracts |
| Profit rule | treaty Article 7 and the method applicable to that treaty |
7. Fixed place, warehouse and home office
A fixed-place PE normally requires a place of business, a degree of permanence, the place being at the enterprise's disposal and business being carried on through it. An office, workshop or factory is a classic example. A warehouse may be excluded when its activity is genuinely preparatory or auxiliary under the applicable treaty, but a core fulfilment or distribution function, fragmented activity or wider local operation may produce a different result.
A home office is not automatically a place of business. The 2025 OECD Model Commentary clarifies that working abroad from home for less than half of total working time would not on its own generally create such a place; even above that level, a commercial reason for carrying on the business from that country remains important. This is interpretive guidance, not a Polish statutory safe harbour, and the actual treaty and facts still control.
8. Construction, assembly and installation projects
Polish domestic law includes a construction site, construction, assembly or installation without specifying a duration. Tax treaties commonly introduce a project-duration threshold, but the number of months and aggregation rules vary. Count the whole connected project, interruptions and work of related contractors according to the exact treaty and any anti-splitting rule; do not reset the clock by issuing new purchase orders.
| Project control | Evidence |
|---|---|
| Scope and sites | master contract, statements of work, locations and commercial unity |
| Start and end | first on-site activity, handover, testing, defects and interruptions |
| People and contractors | travel, timesheets, subcontractors and related enterprises |
| Treaty threshold | exact Article 5 wording and MLI/synthetic text |
| Other exposures | payroll, social security, VAT registration/FE and local licences |
9. Dependent agent and contract authority
A person in Poland may create an agent PE even without a dedicated office. The domestic rule refers to authority to conclude contracts that is actually exercised. Treaty wording may also capture a person who habitually plays the principal role leading to contracts routinely concluded without material modification by the foreign enterprise. Titles and signature blocks are not decisive: analyse the sales process end to end.
- Who identifies and qualifies customers?
- Who sets or negotiates price, scope, warranty and other material terms?
- Can headquarters realistically reject or materially modify the local outcome?
- How often are contracts concluded or renewed through the Polish activity?
- Does the person act for several unrelated principals in the ordinary course of an independent business?
- Are authority limits reflected in email, CRM, approvals and actual behaviour?
10. Branch, subsidiary and registrations are indicators, not conclusions
A Polish subsidiary is a separate legal person and does not automatically become its parent's VAT FE or CIT PE. A registered branch is a strong operational indicator and a listed example in domestic CIT law, but the treaty and actual activity still determine the income-tax result. Conversely, a foreign enterprise may create a PE without registering a KRS branch. VAT or NIP registration is an administrative status, not proof of the substantive FE test.
| Polish footprint | What it proves | What still needs testing |
|---|---|---|
| Subsidiary | separate Polish company exists | parent's access to resources, agency and intercompany activity |
| KRS branch | registered organisational form of the foreign entrepreneur | treaty PE, profit attribution, VAT FE and transaction involvement |
| VAT registration | Polish VAT number and filing status | human/technical resources and place of supply |
| Warehouse or office lease | access to premises | disposal, permanence, function and treaty exclusions |
| Local employee | personnel presence | role, authority, home-office/place test, payroll and VAT resources |
11. Profit attribution and Polish compliance
If a CIT PE exists, Poland does not automatically tax all revenue from Polish customers. The enterprise must attribute profits consistent with the applicable treaty, analysing the functions performed, assets used and risks assumed by the PE and supporting internal dealings on an arm's-length basis where the governing rules require it. This usually demands a separate, reconcilable accounting trail even though the PE is not a separate legal entity.
| Workstream | Typical action |
|---|---|
| Registration and returns | confirm NIP, tax office, CIT advances and annual return |
| Accounting | create Polish cost centres/ledgers and reconcile head-office dealings |
| Profit attribution | document functions, people functions, assets, risks and allocation keys |
| Transfer pricing | support dealings with the head office and related parties under Polish rules |
| Payroll and withholding | test employer/payroll duties and whether payments are effectively connected with the PE |
| VAT | run a separate FE, registration, invoice and JPK analysis |
12. Build an evidence file and change-control process
The best time to test Polish presence is before signing a lease, moving an employee, appointing an agent, launching a warehouse or extending a project. Use one verified fact sheet for VAT, CIT, payroll and legal workstreams, but record separate conclusions. Reopen the file when personnel, system access, decision rights, contract flow, project duration or the treaty position changes.
| Scenario | Questions that usually decide the risk |
|---|---|
| Polish subsidiary serving the parent | are distinct resources placed at the parent's disposal; who receives the service; does the subsidiary negotiate contracts? |
| Warehouse or logistics hub | storage only or core fulfilment; who controls stock, systems and staff? |
| Employee working from a Polish home | working pattern, commercial reason, authority, customer contact and employer requirements |
| Construction or installation | treaty threshold, connected projects, interruptions and subcontractors |
| Sales agent | habitual principal role, approval reality and independence |
| Foreign company buying services for a Polish team | which establishment receives and uses them; whose resources are used? |
- Map entities, contracts, invoices, people, premises, equipment and systems.
- Describe actual decisions and authority, not only written policies.
- Run the VAT receiving/supplying/intervention tests by transaction.
- Run the CIT fixed-place, project and agent tests under the exact treaty.
- Document the conclusion, alternatives and evidence owner.
- Configure invoicing, accounting, CIT, VAT, payroll and reporting.
- Set review triggers and a quarterly cross-border presence register.
- Obtain case-specific advice before correcting historic periods or relying on a treaty exclusion.
inPL can coordinate accounting in Poland, transfer-pricing support and Poland market entry, so the presence analysis, bookkeeping and operating model use the same verified facts.
