Estonian CIT and the Transfer of Partnership Interests
Does a delayed entry in the National Court Register (KRS) deprive a limited partnership of its eligibility for the lump-sum corporate income tax regime? The Provincial Administrative Court in Gliwice, in its judgment of 20 January 2026 (I SA/Gl 575/25), did not resolve this substantive question — but its annulment of the Director of National Tax Information’s individual interpretation opens the path to a taxpayer-favourable construction. The Court found that the interpretive authority had failed to provide any legal justification for its position and had not engaged with the applicant’s argumentation grounded in the provisions of the Commercial Companies Code and the jurisprudence of ordinary courts.
The Subjective Condition: “Exclusively Natural Persons”
Article 28j(1)(4) of the Act of 15 February 1992 on Corporate Income Tax (ustawa o podatku dochodowym od osób prawnych, hereinafter “CIT Act”) conditions eligibility for the lump-sum regime upon a structural requirement: all partners of the limited partnership must be natural persons who do not hold property rights connected with the right to receive benefits as founders or beneficiaries of a foundation, trust, or analogous fiduciary arrangement.
The provision, on its face, is deceptively simple. It requires an assessment of the partnership’s subjective composition at any given moment — yet the CIT Act is conspicuously silent on the question of when a change in partnership composition takes legal effect. This lacuna compels recourse to the substantive provisions of commercial law, generating a point of intersection between tax and company law that the interpretive authorities have, until recently, failed to navigate with adequate rigour.
The Factual Matrix: A 27-Month Discrepancy
The applicant partnership initially comprised a limited liability company (sp. z o.o.) as general partner (komplementariusz) and a natural person as limited partner (komandytariusz). On 20 December 2021, the sp. z o.o. transferred the entirety of its rights and obligations to a natural person by way of a simple written agreement — a form sufficient under Article 10(1) and (2) of the Commercial Companies Code (Kodeks spółek handlowych, hereinafter “CCC”).
The transfer was duly executed, with the consent of all partners as required by statute. However, the partnership’s legal counsel failed to submit the corresponding amendments to the KRS within the statutory seven-day period prescribed by Article 22 of the Act on the National Court Register. The partners’ resolution amending the partnership agreement was adopted on 16 January 2024, the filing with the registry court occurred on 19 January 2024, and the court’s order registering the change was issued on 26 March 2024 — more than 27 months after the underlying transfer.
In the interim, on 31 January 2022, the partnership filed a ZAW-RD notification electing the Estonian CIT regime. From 2022 onwards, it was taxed under the lump-sum system. Its partners were, de facto, exclusively natural persons — yet the KRS continued to list the sp. z o.o. as general partner.
The Interpretive Authority’s Position
In its individual interpretation of 27 February 2025 (0111-KDIB2-1.4010.613.2024.2.ED), the DKIS concluded that the partnership had not satisfied the condition of Article 28j(1)(4) during the tax years 2022–2024. The reasoning turned on a single proposition: the amendment of the partnership agreement regarding the general partner’s identity occurred only on 16 January 2024, and the filing with the KRS took place on 19 January 2024, constituting a violation of Article 22 of the KRS Act.
The analytical deficiency of this position is striking. The DKIS failed to determine whether the transfer agreement of 20 December 2021 was valid and effective. It did not indicate whether KRS registration bears constitutive or declaratory significance. It cited no provision from which a constitutive character could be derived. Most critically, it did not engage with the applicant’s argumentation grounded in Articles 10 and 103 of the CCC and in the case law of ordinary courts.
The Court’s Assessment: Annulment on Procedural Grounds
The Provincial Administrative Court annulled the challenged interpretation for violation of Article 14c(2) of the Tax Ordinance, which mandates that an individual interpretation recognising the applicant’s position as incorrect must contain a legal justification for the authority’s own position.
It must be emphasised that the Court expressly declined to prejudge the substantive question: “The Court at the present stage does not determine the substantive issue presented in the application for an individual interpretation“. The annulment rests entirely on procedural grounds — the inadequacy of the interpretation’s legal reasoning. This means that the DKIS may, in renewed proceedings, theoretically arrive at the same conclusion, provided it furnishes adequate legal justification.
The Court nevertheless identified a fundamental incoherence in the authority’s reasoning. If the DKIS derives a breach of Article 22 of the KRS Act from the failure to register the partner change within seven days of the 2021 agreement, it implicitly concedes that the agreement itself effected the change. Yet simultaneously, the DKIS appears to treat the KRS entry as a precondition — without articulating this position or identifying its legal basis. As the Court observed: “Where the interpretive authority has failed to discharge its statutory obligation to present its own position and its argumentation, the Court has nothing to evaluate”.
The Declaratory Character of KRS Entries: The Applicant’s Argumentation
Although the administrative court did not resolve the material-law question, the applicant’s argumentation — which the DKIS conspicuously failed to rebut — merits examination, as the authority will be required to address it in renewed proceedings.
Under Article 10(1) of the CCC, the aggregate rights and obligations of a partner in a personal partnership may be transferred to another person, provided that the partnership agreement so permits. No further formality — neither notarial form, nor amendment of the partnership agreement, nor KRS registration — constitutes a conditio sine qua non of the transfer’s legal effect.
The Court of Appeal, in its order of 30 June 2020, held expressis verbis that the entry of a given entity in the KRS as a partner bears declaratory character. Whether a given entity holds the status of partner is determined not by the entry itself, but by the legal event to which provisions of substantive law attach the consequence of acquisition or loss of partner status.
Practical Implications
The judgment carries two implications of practical importance. First, it reinforces the standard of adequate reasoning required of interpretive authorities — the DKIS may not dispose of complex company-law questions by mere assertion. Second, the case signals a potentially taxpayer-favourable construction of Article 28j(1)(4), though this question will be resolved only in renewed proceedings or on further appeal.
Limited partnerships utilising or contemplating the Estonian CIT regime should ensure timely KRS registration of partner changes. Where a transfer has already occurred and registration remains outstanding, meticulous documentation — the transfer agreement, evidence of partners’ consent, and contemporaneous correspondence — assumes critical importance.

The law is equal for everyone, but the parties rarely are: on one side stands an organization with time, money, and lawyers, on the other a person with one business, one nest egg, and one life.
Clients rarely come to him with a legal problem. They come with a problem that also has a legal side: an audit that began with a single invoice, money entrusted to someone who has disappeared, a company that has to be passed on before it is too late. Most such matters are decided long before the first letter is written, in decisions made without asking and in deadlines nobody remembered. So he begins by asking how the client got here, not what the client should have done.
He advises entrepreneurs and families from more than a dozen countries, including those whose accounts the tax office has just seized and who do not know what to do tomorrow morning. He defends them in tax audits, customs and fiscal inspections, disputes with the tax authorities, and criminal tax proceedings. He represents victims of investment fraud and Ponzi schemes. He helps families set up family foundations and plan succession, so that a life’s work outlasts a single generation.
Not every case can be won. Every case can be run so that the client knows where they stand. Since 2006 he has represented the victims in the WGI case (Warszawska Grupa Inwestycyjna, the Warsaw Investment Group), one of the longest criminal cases in the history of the Polish financial market, because some things must not be left half finished, even when they take two decades. In the case of the collapsed cryptocurrency exchange Zonda (Zondacrypto, operated by BB Trade Estonia OÜ), he represents several hundred victims in the criminal investigation conducted by Poland’s National Prosecutor’s Office and in the Estonian bankruptcy proceedings.
Kancelaria Prawna Skarbiec is listed in the rankings of Poland’s largest tax advisory firms published by Dziennik Gazeta Prawna and Rzeczpospolita, and it is a four-time recipient (2015 to 2018) of the European Medal awarded by the Business Centre Club and the European Economic and Social Committee. Robert Nogacki publishes regularly, in the press and on the firm’s website, for people who have a problem rather than a law degree, because a legal opinion the client cannot understand protects only the lawyer.
He believes that the best legal advice is the kind that means the client never has to appear in court.
