Estonian CIT rulings in Poland – Supreme Administrative Court (NSA) on dividends, hidden profits and bond contributions
Poland’s Supreme Administrative Court (NSA) rulings clarify Estonian CIT rules on dividends, hidden profits and in-kind bond contributions.
19% PIT on dividends from Estonian CIT profits is calculated on the full amount of distributed profit attributable to the shareholder.
At a 10% Estonian CIT rate, the PIT credit is 90% of the relevant company tax; at a 20% rate, the credit is 70%.
In judgment II FSK 1291/23 of 1 October 2026, the NSA held that bond interest paid to a related party may constitute hidden profits.
In judgment II FSK 1300/23 of 1 October 2026, the NSA confirmed that contributing privately held bonds does not necessarily exclude Estonian CIT.
An in-kind contribution exceeding EUR 10,000 does not, by itself, exclude a company from electing Estonian CIT in Poland.
Company tax does not reduce the PIT base
Estonian CIT is reflected through the statutory PIT credit rather than by first reducing the shareholder’s PIT tax base.
Financing form alone does not determine taxation
Issuing bonds instead of using a loan does not guarantee that related-party interest falls outside the hidden-profits rules.
The nature of contributed assets matters
An in-kind contribution must be assessed by its value, origin and whether the assets are connected with the shareholder’s business.
Tax risk may arise at different stages
Estonian CIT issues may arise when entering the regime, financing operations and later distributing company profits.
Recent Estonian CIT rulings in Poland by the Supreme Administrative Court (NSA) clarify several important aspects of the Polish lump-sum corporate taxation regime. When dividends are distributed, PIT must be calculated on the full amount of profit allocated to the shareholder, while the company’s Estonian CIT liability is accounted for only through the statutory tax credit. Interest on bonds paid to a related party may be classified as hidden profits. By contrast, contributing bonds held as shareholders’ private assets does not necessarily trigger a temporary restriction on a company’s eligibility for Estonian CIT.
These judgments concern different stages of a company’s operations under the Estonian CIT regime, or in preparation for entering it. Dividends relate to the distribution of profits, bonds may be used to finance business operations, and an in-kind contribution may affect whether the company can enter the regime.
From the perspective of management boards and CFOs, the common challenge is to assess the tax consequences before a transaction takes place. In such cases, tax advisory services in Poland may cover not only eligibility for Estonian CIT, but also the implications of a planned distribution, financing arrangement or in-kind contribution. The NSA rulings also demonstrate that the legal form of a transaction does not always determine its tax treatment.

How is PIT calculated on dividends under Estonian CIT in Poland?
The 19% PIT on dividends paid from profits generated while a company was subject to Estonian CIT must be calculated on the full amount of distributed profit attributable to the shareholder. The company’s lump-sum corporate tax liability is not deducted from the PIT tax base beforehand.
This follows, among other rulings, from the NSA judgment of 29 September 2026, case II FSK 1274/23. The Court dismissed the company’s cassation appeal, in which it argued that the profit allocated for distribution should first be reduced by the Estonian CIT payable, with PIT then calculated on the remaining amount.
The NSA had previously adopted a similar position in its judgments of 3 June 2026, case II FSK 992/23, and 18 June 2026, case II FSK 993/23. In the latter judgment, the NSA expressly referred to its earlier ruling in case II FSK 992/23 and endorsed the reasoning presented there.
Why does the company’s tax not reduce the PIT tax base?
Estonian CIT provides a specific mechanism for taxing distributed profits. The company pays lump-sum corporate income tax, while the shareholder is subject to 19% PIT on the dividend.
However, Polish legislation provides a mechanism to reduce the combined tax burden. Under Article 30a(19) of the Polish Personal Income Tax Act, the shareholder’s PIT liability may be reduced by a specified proportion of the company’s lump-sum corporate tax attributable to that shareholder.
Where the company applies the 10% Estonian CIT rate, the PIT credit equals 90% of the relevant portion of the company’s tax. At the 20% rate, the credit equals 70% of the corresponding amount.
The NSA held that reducing the PIT tax base by the company’s tax liability first and then applying the statutory credit would effectively account for the same tax burden twice.
How much tax is payable on dividends under Estonian CIT?
Assume that a company distributes PLN 100,000 in profits generated while it was subject to Estonian CIT. The entire profit is attributable to one individual shareholder and the statutory credit may be applied in full.
| Tax calculation | 10% Estonian CIT rate | 20% Estonian CIT rate |
|---|---|---|
| Distributed profit | PLN 100,000 | PLN 100,000 |
| Company’s Estonian CIT | PLN 10,000 | PLN 20,000 |
| PIT before credit – 19% | PLN 19,000 | PLN 19,000 |
| PIT credit | PLN 9,000 | PLN 14,000 |
| PIT after credit | PLN 10,000 | PLN 5,000 |
| Total CIT and PIT | PLN 20,000 | PLN 25,000 |
This represents 20% and 25% of the distributed profit respectively.
In the first scenario, it would therefore be incorrect to calculate PIT on PLN 90,000 solely because the company is required to pay PLN 10,000 in Estonian CIT.

PIT is calculated on the full distributed profit
In Poland, the 19% PIT on dividends paid from profits generated under Estonian CIT is calculated on the full amount of distributed profit. Poland’s Supreme Administrative Court (NSA) confirmed this in judgment II FSK 1274/23 of 29 September 2026, following earlier rulings II FSK 992/23 and II FSK 993/23.
Company’s argument · rejected
Profit reduced by Estonian CIT first
The company argued that the profit allocated for distribution should first be reduced by the Estonian CIT payable, with PIT then calculated on the remaining amount.
Incorrect: calculating PIT on PLN 90,000 only because PLN 10,000 of Estonian CIT is payable
Position of the NSA
PIT on the full distributed profit
PIT is calculated on the full amount attributable to the shareholder. The company’s Estonian CIT is accounted for only through the statutory credit under Article 30a(19) of the Polish Personal Income Tax Act.
Reducing the base first would account for the same tax burden twice
Tax payable on PLN 100,000 distributed to one shareholder
Profit generated while subject to Estonian CIT, attributable to one individual shareholder; the statutory credit is applied in full.
10% Estonian CIT rate
Total CIT and PIT: PLN 20,000 = 20% of the distributed profit
PIT before credit (19%): PLN 19,000 − PIT credit: PLN 9,000 (90% of PLN 10,000) = PIT after credit: PLN 10,000
20% Estonian CIT rate
Total CIT and PIT: PLN 25,000 = 25% of the distributed profit
PIT before credit (19%): PLN 19,000 − PIT credit: PLN 14,000 (70% of PLN 20,000) = PIT after credit: PLN 5,000
What this means for companies distributing dividends
Review previous PIT calculations: if shareholders’ PIT was calculated on an amount already reduced by the Estonian CIT payable, the method used may require reassessment. Profits generated before entering the regime must be properly separated.

What do the NSA rulings mean for companies distributing dividends?
A company should first establish the period in which the distributed profits were generated. The Estonian CIT mechanism applies to profits earned while the company was subject to the lump-sum regime. Where a distribution also includes profits generated before entering the regime, those amounts must be properly separated.
Previous PIT calculations should also be reviewed. If a company calculated shareholders’ PIT on an amount already reduced by the Estonian CIT payable, the method used may require reassessment.
Can interest on bonds be treated as hidden profits?
Interest on bonds issued by a company subject to Estonian CIT and paid to a related party may constitute hidden profits. The fact that the bondholder is not a direct shareholder of the company does not, by itself, exclude such taxation.
The NSA adopted this position in its judgment of 1 October 2026, case II FSK 1291/23. The dispute concerned financing provided to a company through a bond issue subscribed for by a related entity.
The company argued that Article 28m of the Polish Corporate Income Tax Act expressly refers to interest on loans and credit facilities but does not specifically mention interest on bonds. The NSA rejected this distinction. In the circumstances examined, the bonds performed a financing function economically comparable to a loan provided by a related party.
Why does the form of financing not always determine its taxation?
Hidden profits include benefits connected with the right to participate in profits, other than formally distributed profits, where the beneficiary is a shareholder or a specified related party. The catalogue set out in Article 28m(3) of the Polish Corporate Income Tax Act is broad. The examples listed there include interest, commissions and other charges connected with loans provided to the taxpayer by specified parties.
The NSA judgment demonstrates that the assessment of financing arrangements cannot be based solely on the name of the financial instrument.
Replacing a loan with a bond issue does not automatically guarantee that interest paid to a related party will fall outside the scope of Estonian CIT taxation as hidden profits.
Estonian CIT in Poland · hidden profits
Bond interest paid to a related party may be hidden profits
In judgment II FSK 1291/23 of 1 October 2026, Poland’s Supreme Administrative Court (NSA) held that interest on bonds issued by a company subject to Estonian CIT and paid to a related party may constitute hidden profits (Article 28m of the Polish Corporate Income Tax Act).
01
Bonds subscribed for by a related entity
Financing is provided to a company subject to Estonian CIT through a bond issue. The fact that the bondholder is not a direct shareholder does not, by itself, exclude such taxation.
02
Bonds economically comparable to a related-party loan
The company argued that Article 28m refers to interest on loans and credit facilities, not bonds. The NSA rejected this: the bonds performed a financing function economically comparable to a loan.
03
Interest may constitute hidden profits
Replacing a loan with a bond issue does not guarantee that interest paid to a related party falls outside Estonian CIT taxation as hidden profits. It may trigger a current tax liability for the company.

What does the ruling mean for intra-group financing?
The significance of the judgment extends beyond bond financing itself. When planning financing between related entities, a company should assess both the commercial terms of the transaction and its implications under Estonian CIT. This is particularly relevant for structures where financing is provided by shareholders or other companies within the same group.
The cost of such financing should therefore not be assessed solely on the basis of the interest rate. If the interest paid is classified as hidden profits, it may trigger a current tax liability for the company.
Does contributing bonds prevent a company from electing Estonian CIT?
Not every in-kind contribution of bonds results in a temporary restriction on eligibility for Estonian CIT. A key consideration is whether the contributed assets constitute an enterprise, an organised part of an enterprise or assets belonging to an enterprise. This follows from the NSA judgment of 1 October 2026, case II FSK 1300/23. The Court dismissed a cassation appeal in a case concerning an in-kind contribution of bonds or receivables relating to their redemption.
In that case, the shareholders contributed assets belonging to their private estates rather than assets forming part of an enterprise. The NSA concluded that, in those circumstances, the conditions for applying the temporary exclusion from the Estonian CIT regime had not been met.
Why does the origin of contributed assets matter?
Article 28k of the Polish Corporate Income Tax Act provides restrictions on electing Estonian CIT in connection with specified restructuring transactions and in-kind contributions. These provisions refer, among other things, to an enterprise, an organised part of an enterprise and business assets exceeding the statutory value threshold.
The NSA confirmed that establishing that an in-kind contribution exceeds the equivalent of EUR 10,000 is not sufficient on its own.
The exact nature of the contributed assets must also be examined. Where bonds belonged to shareholders’ private assets and did not constitute assets of a business operated by those shareholders, their contribution cannot automatically be treated as triggering a temporary exclusion for the receiving company under Article 28k(1)(6), read together with Article 28k(2), of the Polish Corporate Income Tax Act.
Does an in-kind contribution exceeding EUR 10,000 automatically exclude Estonian CIT?
No. Exceeding the EUR 10,000 threshold is not an independent ground for excluding a company from electing Estonian CIT. The threshold must be considered together with the nature of the assets contributed.
Judgment II FSK 1300/23 is particularly relevant in practice. It demonstrates that an in-kind contribution must be assessed not only by reference to its value but also by examining the origin and nature of the contributed assets.
However, this does not mean that every contribution of bonds is neutral for Estonian CIT eligibility. If the securities formed part of an enterprise’s assets or the transaction formed part of another operation covered by the exclusions under Article 28k, the outcome could be different.
What should a company check before making an in-kind contribution?
Before making an in-kind contribution, it is advisable to establish how the assets were acquired, how they have previously been used and whether they are connected with the shareholder’s business activities. Documents confirming ownership of the bonds, their value and the nature of the assets from which they originate are also relevant.
The analysis should preferably be carried out before the contribution is made and before determining the date on which the company intends to elect Estonian CIT. This allows the company to assess whether the proposed capital contribution could result in a temporary restriction on entering the regime.

Contributing bonds does not necessarily exclude Estonian CIT
In judgment II FSK 1300/23 of 1 October 2026, Poland’s Supreme Administrative Court (NSA) held that an in-kind contribution must be assessed not only by its value but also by the origin and nature of the contributed assets (Article 28k of the Polish Corporate Income Tax Act).

What do the latest Estonian CIT rulings in Poland mean for companies?
The judgments discussed concern three different stages of a company’s operations: electing Estonian CIT, financing business activities and distributing profits.
| Area | Position resulting from the case law | Implications for the company |
|---|---|---|
| Dividend | PIT is calculated on the full amount of distributed profit, while the company’s Estonian CIT is accounted for through the statutory credit | Review PIT calculations and withholding obligations |
| Bond interest | Interest paid to a related party may constitute hidden profits | Assess the tax cost of intra-group financing |
| In-kind contribution of bonds | Contributions of shareholders’ private assets do not necessarily trigger a temporary exclusion from Estonian CIT | Analyse the origin and nature of contributed assets |
From a management perspective, an important conclusion is that tax risks may arise both before entering the Estonian CIT regime and while applying it.
For an in-kind contribution, the issue may concern the company’s eligibility to elect Estonian CIT. For financing, it may involve the recognition of hidden-profit income. For dividend distributions, the challenge is to calculate PIT correctly and apply the appropriate statutory credit.
Do NSA rulings change the Estonian CIT rules?
No. NSA judgments do not introduce new legislation. Instead, they demonstrate how existing Polish tax provisions are interpreted in specific factual circumstances. Nevertheless, they have considerable practical significance.
In relation to dividends, several consistent NSA judgments indicate an increasingly established interpretation of the PIT tax base.
The bond-related ruling demonstrates that the assessment of hidden profits may take into account the economic function of a transaction rather than only the legal name of the instrument.
The ruling concerning the in-kind contribution confirms that applying the restrictions under Article 28k of the Polish Corporate Income Tax Act requires a detailed examination of the nature of the contributed assets.
This does not mean that every taxpayer in an apparently similar situation will obtain the same result. Before applying conclusions drawn from a judgment, companies should compare their own circumstances with the facts considered by the NSA.
How can companies reduce tax risks under Estonian CIT?
Companies applying Estonian CIT should assess the tax consequences of material transactions before they are carried out.
When distributing profits, companies should determine the period in which those profits were generated and correctly calculate shareholders’ PIT. Where financing is obtained from related parties, the risk of hidden-profit taxation should be examined. For planned in-kind contributions, the origin of the assets and the transaction’s impact on eligibility for Estonian CIT are particularly important.
The latest Estonian CIT rulings in Poland demonstrate that the regime involves more than the taxation of dividend distributions. The movement of funds and assets between a company, its shareholders and related parties may affect both eligibility for the regime and the timing of the company’s tax liability.
If a company is planning to elect Estonian CIT, distribute profits, obtain financing from a related party or make an in-kind contribution, the tax implications should be assessed in advance.
