Could Your Foreign Subsidiary Be a Polish Corporate Income Tax Resident?

Could Your Foreign Subsidiary Be a Polish Corporate Income Tax Resident?

Your subsidiary is registered in Ireland, Estonia, or the Netherlands. It has a local tax identification number and formally operates abroad. Yet its directors join meetings from Warsaw, resolutions are drafted by the legal team of its Polish parent company, and a director signs contracts from an office in Poland.

The Polish tax authorities may regard that subsidiary as a Polish corporate income tax (CIT) resident, taxable in Poland on its worldwide income-including for earlier years.

Article 3(1) of Poland’s CIT Act applies unlimited tax liability to taxpayers with either a registered office or a place of management in Poland. Meeting either condition is enough. Foreign registration does not settle the question if the company is actually managed from Poland.

This article explains how to assess that risk, what the financial consequences may be, and what to review before changing a foreign subsidiary’s management structure.

Key terms

When can a foreign subsidiary become a Polish CIT taxpayer?

The test concerns what happens in practice

Article 3(1a) of the CIT Act provides that a taxpayer has a place of management in Poland when its day-to-day affairs are conducted there in an organized and continuous manner. The provision identifies, in particular, three categories relevant to the assessment:

1. Documents governing the company’s operations, including agreements, decisions, and court judgments.
2. Powers of attorney that have been granted.
3. Relationships within the meaning of Article 11a(1)(5) of the CIT Act.

The list is not exhaustive: “in particular” allows the tax authority to consider other circumstances.

There is no arithmetic safe harbor based on days spent abroad, the allocation of remuneration, or the address at which a meeting is formally convened. The central question is where decisions actually come from.

What the Polish tax authorities examine

Poland’s National Revenue Administration (Krajowa Administracja Skarbowa, or KAS) can examine how the company is run, rather than relying solely on its registration documents. The source identifies the following recurring factors in rulings issued by the Director of the National Tax Information Service (Krajowa Informacja Skarbowa, or KIS) in 2025 and 2026:

Three rulings illustrating the approach

• April 17, 2026 – ruling 0114-KDIP2-2.4010.80.2026.1.ASK. A subsidiary formally registered in Austria was managed from Poland. The Director of KIS found its place of effective management in Poland because strategic and financial decisions, day-to-day direction, and oversight of assets took place there. The company was treated as a Polish tax resident.
• March 7, 2025 – ruling 0111-KDIB1-2.4010.746.2024.2.AK. The case concerned an offshore company with international company status in the United Arab Emirates. Citing a Supreme Administrative Court judgment (II FSK 2475/14), the Director of KIS found its place of effective management in Poland and treated it as a Polish resident.
• April 5, 2024 – ruling 0114-KDIP2-1.4010.136.2020.16.S.SP.MW. The ruling confirmed the priority of actual management over the place of registration in the assessment described in the source.

The practical point is consistent: a foreign registered office and an entry in a foreign register do not, by themselves, rule out Polish tax residence.

A common risk pattern in corporate groups

Risk often grows gradually as management functions move to Poland. The source describes this pattern:

1. A foreign subsidiary appoints a management body composed entirely of Polish tax residents.
2. Its members work in person abroad for part of the year and remotely from Poland for the rest.
3. A separate board of directors, where the structure has one, is also predominantly made up of people from Poland.
4. The Polish parent supplies IT support and administration from Poland.
5. Individuals holding roles in both companies have no clearly separated responsibilities.
6. The subsidiary has no office, staff, infrastructure, or other operational resources of its own in its state of registration.

If at least three of these features apply to your group, the source treats the risk of a residence reclassification as elevated. That is a practical warning sign, not a statutory numerical test.

Meeting minutes may contradict the formal address

Suppose a meeting is convened at an address abroad, but two of three members join by video from Warsaw and the Polish parent’s legal team prepares the papers. The record may depict management from Poland, despite the meeting’s formal location.

Minutes recording where participants joined from, who prepared resolutions, and where documents were signed can tell a different story from travel schedules. Documentation should accurately reflect how decisions were made-not attempt to create an appearance that differs from practice.

What could Polish residence cost?

CIT on worldwide income, potentially for earlier years

If the Polish tax authority treats the foreign company as a Polish tax resident, it becomes subject to Polish CIT on all its income, wherever earned. The rates stated in the source are 19%, or 9% for small taxpayers and taxpayers starting a business, up to a EUR 2 million revenue threshold.

The exposure may reach five years back. Under Article 70 § 1 of the Polish Tax Ordinance, the limitation period is counted from the end of the calendar year in which the tax payment deadline fell.

Late-payment interest

Under Article 53 § 1 and § 4 of the Tax Ordinance, interest runs from the day after the payment deadline until payment. Paying tax abroad does not itself stop Polish late-payment interest from accruing; the source notes that Polish law provides no mechanism with that effect.

Fiscal penal exposure for individuals

Poland’s fiscal penal rules can create exposure for individuals, including management body members, rather than imposing fiscal penal liability on the company itself. The source identifies these provisions of the Polish Fiscal Penal Code (Kodeks karny skarbowy, or KKS):

The source states that the limitation period for punishability is five years for acts punishable by a fine, restriction of liberty, or imprisonment of up to three years, and 10 years for acts carrying a more severe penalty, under Article 44 KKS. Proceedings commenced against the alleged offender extend the respective period by a further five or 10 years.

These are possible exposures, not an assertion that every residence dispute results in an offense. For more background, see our article on liability in a Polish limited liability company.

Dual residence and MAP

If both Poland and the other state claim the company as a tax resident, a dual-residence conflict arises. The source identifies two routes relevant to resolving it:

1. The applicable treaty’s tie-breaker. A classic formulation, used for example in the Poland-Germany treaty described below, applies the place-of-effective-management test.
2. MAP. An application is made to Poland’s Minister of Finance, generally within three years of the first official notification of an action resulting in taxation contrary to the treaty.

The source describes MAP as free of charge but without a guaranteed completion date: double tax treaties do not set a maximum period for the states to reach agreement. It also states that commencing MAP suspends the limitation period for the tax liability for no more than three years in total. There is no appeal against an agreement reached through the procedure. The result is uncertain, and managing the process can be organizationally costly.

What to review before changing the management structure

The best time to assess the model is before appointing new members. Changes made afterward alter an arrangement already in operation and may appear to be a response to identified tax risk. If appointments have already been made, review is still possible, but the reasons for and implementation of any changes require care.

Separate overlapping roles clearly

When one person serves both the Polish parent and the foreign subsidiary, document which decisions they make for each company. Without a clear division, the evidence may show one individual making decisions for both from Poland.

The document must match actual authority and conduct. A written allocation alone will not relocate decision-making.

Examine what intragroup contracts really provide

Agreements for IT, administration, legal support, accounting, and similar services can show where the subsidiary’s day-to-day affairs are carried out. They may be among the strongest evidence against a claim that management occurs abroad.

Ask:

1. Do the services extend into the subsidiary’s management functions?
2. Does the service fee reflect market terms?
3. Does the subsidiary have its own resources to perform functions that it formally outsources to the parent?

Test whether the subsidiary has substance abroad

A company with no office, staff, or infrastructure in its state of registration is difficult to defend as managed there, whatever its formal governance structure. An apparently well-designed board will not resolve the underlying issue if the Polish parent provides all services from Poland.

How double tax treaties and OECD principles fit in

Place of effective management is not the only treaty approach

Article 4(3) of the classic version of the OECD Model Tax Convention used POEM to resolve corporate residence conflicts. Paragraph 24 of the Commentary describes it as the place where key management and commercial decisions necessary to conduct the entity’s business are made.

Newer versions move away from an automatic POEM tie-breaker toward resolution by mutual agreement. The source states that Article 4(3) of the Poland-Germany treaty of May 14, 2003, still uses the classic POEM test and that work on an amending protocol is ongoing. A group should therefore check the treaty relevant to its subsidiary rather than assume every treaty uses the same test.

The source’s account of the Polish legislative trend

The approved source points to a broader emphasis on management as a basis for Polish CIT treatment:

1. January 2021: Certain registered partnerships with a specified composition of partners became subject to rules referring to a registered office or place of management in Poland under Article 1(3)(1a) of the CIT Act.
2. May 2021: Limited partnerships became subject to CIT.
3. January 2022: Article 3(1a) clarified the place-of-management concept.
4. January 2026: The words “or place of management” were added to provisions concerning fund exemptions.

According to the source, the explanatory memorandum to the 2026 amendment says that tax residence is determined by a registered office or effective management in a state, and that adding “or place of management” brings further provisions into closer alignment with the concept of tax residence.

How widespread is the issue?

At the end of 2023, Polish corporate groups held 3,654 foreign subsidiaries in 100 countries, according to Statistics Poland data cited in the source. At the end of 2024, 24,773 domestic entities in Poland belonged to enterprise groups, whose aggregate equity was PLN 1,080.5 billion.

Those figures do not establish how many foreign subsidiaries are managed from Poland. Statistics Poland does not collect data on their place of effective management.

The source also reports that KAS carried out 2.64 million verification activities in 2025, while findings from enforcement activities rose 29.1% against 2024. Customs and tax inspections numbered 8,722 in 2025, down 11.3%, while the amount identified through verification activities grew by more than PLN 1 billion in 2024 compared with 2023.

There are no publicly available figures for inspections specifically concerning foreign-company residence based on Polish management. The source notes that growing exchange of information between EU tax authorities and automatic reporting, including country-by-country reporting and DAC6, may make relevant structures easier to identify.

Restructuring needs a business reason

A management restructuring motivated solely by tax considerations may be challenged under the general anti-avoidance rule. The authorities may dispute the tax treatment of profits if they conclude that the steps lacked a business rationale.

Document why the company is changing its structure-for example, market development, a need for local expertise, or a changed operating strategy. The explanation should correspond to what the business actually does, not merely to the intended tax result.

Risk reduction is not a guarantee

None of these measures eliminates Polish residence risk. Together, accurate records, distinct responsibilities, real resources abroad, and a consistent management model can materially change the evidence an authority would need to assess.

The decisive issue remains where and how the subsidiary is genuinely managed. Formal documentation is useful when it records that reality; it cannot substitute for it.

Planning appointments to a foreign subsidiary?

Review CIT residence risk before appointing a new management body, or assess the existing arrangement before making corrective changes. We help IT, SaaS, and e-commerce groups:

• Assess a foreign subsidiary’s Polish CIT residence risk.
• Review intragroup agreements for evidence of management from Poland.
• Separate individuals’ responsibilities in parent and subsidiary.
• Organize meeting minutes, powers of attorney, and residence certificates.
• Design governance arrangements that reduce-but cannot eliminate-the risk.

Frequently asked questions

Does appointing Polish tax residents to a foreign company’s management body make it a Polish tax resident?

Not by itself. The authority assesses the full picture: where decisions are made, where day-to-day activities are directed, the relationships between group companies, and the intragroup arrangements. A combination of factors pointing to Poland raises the risk.

How many days must directors spend abroad?

There is no numerical threshold in the test described here. Days spent abroad are relevant evidence, but the assessment under Article 3(1a) concerns where day-to-day affairs are conducted in an organized and continuous manner.

Are meetings safe if they are formally convened at a foreign address?

No. Remote attendance from Poland, documents prepared by the Polish parent, and resolutions signed in Poland may point in a different direction. The authority can examine minutes and the practical decision-making process, not just the address on the notice.

Which intragroup services warrant particular attention?

IT, administration, accounting, legal, and HR agreements merit review. If their scope shows that functions attributed to the subsidiary-such as bookkeeping, personnel management, or customer service-are in practice carried out from Poland, they may be significant evidence about where its day-to-day affairs are conducted.

Is it too late if the new management body has already been appointed?

No, but proceed carefully. A later change may be viewed as a response to tax risk. Ensure it has a genuine business rationale, reflects the operating model, and is implemented consistently. Advice on the sequence of changes should include consideration of the general anti-avoidance rule.

What if Poland treats the subsidiary as a CIT resident?

The source identifies potential Polish CIT on worldwide income at 19% or, where applicable, 9%, exposure reaching five years back, and late-payment interest. Individuals may also face fiscal penal exposure where the relevant offense requirements are met. If the other state also claims residence, the applicable treaty and possibly MAP become important; MAP has neither a guaranteed completion date nor a guaranteed favorable outcome.
