Estonian CIT should be assessed alongside reinvestment plans, profit distributions and shareholder transactions. We check entry conditions and the implications of maintaining the regime.
Does Estonian CIT fit your company’s growth plans? We compare tax models using its financial data, check eligibility and help prepare the transition. After implementation, we assess distributions, shareholder transactions and the risk of hidden profits.
Estonian CIT
Your company earns profits, retains them to finance further purchases, and advance payments of standard corporate income tax put pressure on cash flow. Estonian CIT, formally the lump-sum tax on corporate income, changes when and how taxation arises. Opting in affects settlements in subsequent years, so the calculation should include planned distributions and transactions with shareholders.
Entering the regime is one decision; remaining eligible requires monitoring the conditions over the years that follow. We calculate whether it is worthwhile using the company’s data and assess transactions with shareholders before they take place.
Let’s check whether this regime suits your company
Is Estonian CIT worthwhile?
Before choosing a model or entering into a significant transaction with a shareholder, it is worth calculating the implications using actual data. This is particularly relevant where:
- the company reinvests most of its profits and rarely or never pays dividends;
- you plan to purchase fixed assets and want to preserve cash flow;
- all shareholders are individuals and the ownership structure is straightforward;
- you have received a general recommendation to switch without a comparison of the tax outcomes;
- the company already uses the regime and plans a lease, loan or services transaction with a shareholder;
- you are considering bringing in an investor, a conversion or a contribution in kind.
In the last two situations, assessment should precede the transaction. The result may be taxation of a hidden profit or loss of eligibility for the regime.
How the lump-sum tax on corporate income works
Under standard CIT, a company accounts for income for the tax year. Under the lump-sum regime, taxable categories include profits allocated for distribution to shareholders, hidden profits and expenditure unrelated to business activities. Retaining profits in the company generally defers taxation of those profits, but does not exclude tax on the other categories listed in Article 28m of the CIT Act.
| Criterion | Standard CIT | Estonian CIT |
|---|---|---|
| Timing of taxation | On an ongoing basis on income for the tax year | Including on profit distribution and hidden profits |
| Advance payments on current income | Generally yes | Not under this model; other taxable events have their own deadlines |
| Company tax rate | 9% or 19%, depending on the conditions | 10% for small taxpayers or companies starting a business; 20% for others |
| Combined taxation of profits distributed to an individual | Approximately 26.29% or 34.39% | Approximately 20% or 25% for a model profit distribution, subject to the assumptions applicable to the particular variant |
| Legal basis | General rules of the CIT Act | Chapter 6b of the CIT Act |
The comparison of the combined burden concerns a typical distribution of profits to an individual shareholder, applying the relevant CIT rate and crediting part of the lump-sum tax against the shareholder’s personal income tax. It does not replace a calculation for a specific company.
The regime is elected for four tax years and renews automatically for another period if the conditions are met. An earlier exit is possible with effect at year-end, but its consequences must also be included in the calculation.
Conditions for entering Estonian CIT
The conditions in Article 28j of the CIT Act must be met jointly. The company must continue to satisfy them while using the regime.
| Condition | What needs to be checked |
|---|---|
| Legal form | A limited liability company, joint-stock company, simple joint-stock company, limited partnership or limited joint-stock partnership |
| Shareholders or partners | Only individuals meeting the statutory conditions |
| Equity interests | No specified interests or rights in other entities |
| Revenue structure | Passive revenue specified in the Act below 50% of the previous year’s revenue, including VAT |
| Employment | Generally three non-shareholder employees for the required period, or the statutory alternative based on remuneration paid under other contracts |
| Reporting | No financial statements prepared under IAS during the lump-sum regime |
| Notification | ZAW-RD by the end of the first month of the first year of taxation under the regime |
A small taxpayer benefits from a less demanding employment condition in the first year of the regime: one full-time employee or the required remuneration for one person under another contract is sufficient. A company starting a business is exempt from this condition in its first year and, from the second year, increases employment by at least one full-time position annually until it reaches three. These are separate rules.
Entering during the year is possible, but requires closing the accounting books and preparing financial statements as at the day preceding the change. Separately, Article 28k excludes, among others, financial enterprises, lending institutions, taxpayers in bankruptcy or liquidation and taxpayers earning exempt income in a Special Economic Zone (SSE) or the Polish Investment Zone (PSI). If you are considering both options, compare them before making the investment decision.
Hidden profits: issues often arise after implementation
Hidden profits include certain benefits provided to shareholders or related parties in connection with the right to participate in profits. The Act gives examples and exclusions, but the classification of a particular transaction depends on its circumstances.
In practice, loans granted to shareholders or related parties, property rented from a shareholder, related-party services and the use of cars particularly require analysis. An arm’s-length price alone does not resolve every issue. We examine the function of the benefit, its business rationale and its connection with profit participation.
Tax on hidden profits is generally payable by the 20th day of the month following payment or provision of the benefit. For distributed profits, the deadline is generally the end of the third month of the year following the year in which the distribution resolution was adopted (Article 28t of the CIT Act).
Loss of eligibility and the consequences of exit
Article 28l of the CIT Act distinguishes between different dates of loss of eligibility. A voluntary exit or failure to meet certain conditions takes effect at the end of the tax year. Some breaches cause eligibility to end at the close of the year preceding the event; in practice, this requires the current year to be taxed under the general rules.
Profits earned during the regime and the possibility of electing it again also matter. ZAW-RD may be filed again only after 36 months following the calendar year in which eligibility expired. We therefore calculate the implications of an ownership change, conversion or contribution in kind before the transaction.
How Tax Legal Partner handles Estonian CIT
Our Estonian CIT practice is led by Przemysław Szot, co-author of “Estoński CIT. Ryczałt od dochodów spółek”, published by C.H. Beck, whose second edition appeared in 2025. We begin with calculations and an assessment of the conditions, then revisit them as the company makes ongoing decisions after implementation.
Our support covers:
- comparing Estonian CIT with the standard model using the company’s data and profit distribution plans;
- checking the conditions in Article 28j and the exclusions in Article 28k before filing ZAW-RD;
- preparing entry-related settlements, including analysis of the initial CIT/KW adjustment and conversion income where applicable;
- reviewing agreements and transactions with shareholders and related parties for hidden profits;
- monitoring eligibility and ongoing tax settlements during the regime;
- assessing the implications of a planned transaction, contribution in kind, conversion or new investor;
- applications for individual tax rulings where confirmation of a position is needed;
- representation in verification activities, audits and proceedings concerning the regime.
If a matter develops into a dispute with the authority, we continue handling it through our tax audits and disputes practice.
How we work together
Calculations before a decision. We compare both models using data on revenue, employment, planned distributions, investments and shareholder transactions. We identify the assumptions under which the regime makes sense and when the outcome changes.
Entry. We check the conditions and prepare the notification and required settlements. We also review shareholder agreements to establish the consequences of performing them after the change of model.
Maintaining eligibility. We monitor the conditions in subsequent years and assess planned transactions before implementation. If an audit arises, we agree on a strategy and act as your representatives.

Frequently asked questions
The company’s lump-sum tax is 10% of the tax base for small taxpayers and companies starting a business, and 20% for others. For a model distribution to an individual, allowing for the credit of part of the lump-sum tax against the shareholder’s personal income tax and subject to the relevant assumptions, the combined burden may be approximately 20% or 25%. These are not universal Estonian CIT rates; the final outcome depends on the company’s situation, the type of income and how profits are distributed.
Among other requirements, all shareholders must be individuals, the company must not hold certain equity rights in other entities and passive revenue must remain below the statutory threshold. The employment or remuneration expenditure condition and the other requirements in Article 28j of the CIT Act must also be met. Different concessions apply to small taxpayers and companies starting a business.
No. Only individuals meeting the statutory conditions may be shareholders in a company using the regime. Any ownership restructuring must be assessed together with the tax consequences of the reorganisation itself.
Article 28m of the CIT Act lists a loan granted by the company to a shareholder or related party as an example of a benefit requiring assessment for hidden profits. The direction of the funds, the substance of the benefit and the circumstances of the transaction matter. A loan received by the company from a shareholder should not automatically be treated in the same way.
Yes. A company may opt out with effect at the end of the tax year. Before leaving, it needs to calculate the tax treatment of profits earned during the regime and allow for the rule that re-entry is possible only after 36 months following the calendar year in which eligibility expired.
Taxpayers earning tax-exempt income from activities in a Special Economic Zone or under a support decision are excluded from the regime under Article 28k of the CIT Act. Before investing, compare both options and establish whether an exclusion applies and from when.
