Estonian CIT in Poland: Eligibility, Hidden Profits, and Exit Rules
05.08.2026
Estonian CIT Poland, formally known as the lump-sum taxation of company income, is a corporate income tax regime under which tax is generally deferred until profit is distributed or otherwise transferred to shareholders or related parties. Instead of annual taxation of accounting profit, the regime focuses on defined events such as dividends, hidden profits and non-business expenditure.
The framework is regulated primarily by Chapter 6b of the Polish Corporate Income Tax Act of 15 February 1992, especially Articles 28c-28t [1]. It can improve cash flow where profits are retained and reinvested, but eligibility and transaction controls require careful assessment.
Estonian CIT in Poland – eligibility conditions
Estonian CIT is available to entities subject to Polish CIT, including limited liability companies, joint-stock companies, simple joint-stock companies, limited partnerships and joint-stock limited partnerships, provided that statutory conditions are met.
The principal conditions under Article 28j of the CIT Act include the following:
- shareholders must be exclusively natural persons;
- the company may not hold shares, stocks, participation rights or similar rights in another entity, subject to limited statutory exceptions;
- less than 50% of annual gross revenue may arise from specified passive sources, including receivables, interest, royalties, guarantees and certain transactions with related parties where little or no economic value is added;
- the company must meet employment or payroll-expenditure requirements;
- the company cannot prepare financial statements under International Financial Reporting Standards on the basis specified in the Accounting Act.
There is no general revenue ceiling for entering the regime. The status of a small taxpayer remains relevant, however, because it affects the applicable tax rate.
Estonian CIT with foreign shareholders
Foreign shareholders do not automatically prevent access to Estonian CIT. A foreign individual may hold shares in an Estonian CIT company, provided that the shareholder is a natural person. The shareholder’s tax residence is not itself an eligibility condition under Article 28j(1)(4) of the CIT Act.
The position changes where a foreign corporate vehicle, fund or holding company becomes a shareholder. Because shareholders must generally be natural persons, a corporate shareholder will normally disqualify the company. Equally important, the Polish company itself cannot generally hold interests in subsidiaries or other entities.
Three important exclusions from the regime
Some entities cannot use lump-sum taxation of company income Poland, even where the general eligibility conditions appear to be met. In particular, exclusion applies to:
- financial enterprises within the meaning of Article 15c(16) of the CIT Act;
- credit institutions and certain other regulated financial-sector entities;
- taxpayers earning income exempt under rules for special economic zones or the Polish Investment Zone, under Article 17(1)(34) and 17(1)(34a) of the CIT Act.
Entities in liquidation or bankruptcy are also excluded. Companies created through certain mergers, divisions, asset contributions or restructurings may face a temporary exclusion. The exact result depends on the structure and timing of the transaction under Article 28k of the CIT Act.
Deadline to switch to Estonian CIT
The standard deadline to switch to Estonian CIT is the end of the first tax year in which the company intends to apply the regime. The taxpayer submits a ZAW-RD notification to the competent head of the tax office, in accordance with Article 28j(1)(7) of the CIT Act.
A company may also enter during the tax year. This requires closing accounting books, preparing financial statements and meeting the statutory conditions before the new taxation period begins. A mid-year election can therefore create additional accounting work and should be coordinated with dividend plans, related-party settlements and financial reporting.
The election generally applies for four consecutive tax years. It is automatically renewed for further four-year periods unless the company resigns within the statutory deadline [1].
Hidden profits Estonian CIT examples
Hidden profits are one of the most important risk areas. Under Article 28m(3) of the CIT Act, they are benefits, whether cash or non-cash, provided directly or indirectly to a shareholder or a related party, other than a formal profit distribution.
Examples may include:
- a loan, credit or similar financing granted to a shareholder or a related entity;
- excessive rent paid by the company for property owned by a shareholder;
- payments for advisory, management or licensing services where the price exceeds market value or the service has no genuine business purpose;
- excessive remuneration connected with share redemption or reduction of share capital;
- private expenses of shareholders paid by the company.
The statutory list is not limited to artificial arrangements. A commercially documented transaction may still be treated as a hidden profit if it transfers value to a shareholder or related party beyond what independent parties would accept.
Three practical exceptions should also be noted. First, employee and civil-law remuneration paid to an individual is excluded up to statutory limits based on five times the relevant average remuneration. Second, expenditure and depreciation relating to assets used exclusively for the company’s business purposes are not hidden profits. Third, a genuine dividend distributed from after-tax profit is not a hidden profit because it is taxed separately as distributed profit under Article 28m(1)(1) [1].
Tax rates and payment timing
The Estonian CIT rate is 10% for a small taxpayer and for a taxpayer starting business activity, and 20% for other taxpayers. These rates apply at company level under Article 28o of the CIT Act. The shareholder’s tax settlement may reduce the effective combined burden in qualifying cases, but the final outcome depends on the shareholder’s status, residence and applicable double tax treaty.
Tax is generally due by the 20th day of the month following the month in which the taxable event occurs, for example a dividend resolution, hidden-profit payment or non-business expenditure [1].
Consequences of exiting Estonian CIT
A company may resign from the regime by filing a declaration by the end of the final tax year of the applicable four-year period. Loss of an eligibility condition may also result in exit. The consequences of exiting Estonian CIT depend on why and when the regime ends.
After exit, the company returns to ordinary CIT principles and must again calculate taxable income on an annual basis. It must also review retained earnings, reserves, deferred tax positions and transactions initiated during the Estonian CIT period. A premature exit can affect cash-flow planning, particularly where profits have been retained but are expected to be distributed after the regime ends.
A taxpayer that resigns may generally re-enter only after three tax years, counted from the end of the tax year in which resignation occurred, pursuant to Article 28l(2) of the CIT Act. This restriction makes an exit decision commercially significant.

FAQ – Estonian CIT in Poland
Can a Polish company with foreign individual shareholders use Estonian CIT?
Yes, in principle. Foreign tax residence does not exclude a shareholder, provided that shareholders are natural persons and all other Article 28j conditions are satisfied.
Can a company with a foreign corporate shareholder enter Estonian CIT?
Generally no. The regime requires shareholders to be exclusively natural persons. A foreign company, fund or other legal entity holding shares will normally prevent eligibility.
Is a dividend the same as a hidden profit?
No. A dividend is an overt distribution of profit. Hidden profits concern other benefits provided to shareholders or related parties, such as non-market rent, loans or private expenditure paid by the company.
Does Estonian CIT apply only to newly established companies?
No. Existing companies may elect the regime if they meet statutory conditions and submit the required notification within the applicable deadline.
Can a company leave Estonian CIT at any time?
Voluntary resignation is generally effective at the end of the four-year taxation period. Earlier exit may occur if eligibility conditions are lost or other statutory exit events arise.
Does holding shares in another company affect eligibility?
Yes. As a general rule, an Estonian CIT taxpayer cannot hold shares, stocks or similar participation rights in another entity. Limited statutory exceptions should be assessed against the specific facts.
