What is Estonian CIT?

Estonian CIT (officially: ryczałt od dochodów spółek, or lump-sum tax on company income) is an alternative form of corporate income tax (CIT) in Poland, where tax is paid only when profits are distributed (as dividends) to shareholders. As long as profits remain in the company and are reinvested, no tax is charged.

This model is inspired by the Estonian tax system, which since 2000 has applied the principle of taxing only distributed profits. In Poland, Estonian CIT was introduced in 2021, and since 2022 it has been available in a significantly simplified and more accessible form.

Who Can Use Estonian CIT?

The lump-sum tax on company income is available to the following legal forms:

  • limited liability company (sp. z o.o.),
  • joint-stock company (S.A.),
  • simple joint-stock company (P.S.A.),
  • limited partnership (spolka komandytowa),
  • limited joint-stock partnership (spolka komandytowo-akcyjna).

Eligibility Conditions

To use Estonian CIT, a company must meet all of the following conditions simultaneously:

  1. All shareholders must be natural persons -- the company cannot have other companies or legal entities as shareholders.
  2. The company does not hold shares in other entities -- it cannot be a shareholder in another company or hold units in investment funds.
  3. Employment of at least 3 employees on employment contracts (who are not shareholders) for at least 300 days in the tax year, or incurring expenditure on remuneration under commission/work contracts for at least 3 persons in an amount of at least three times the average salary.
  4. Passive income (interest, royalties, receivables, related-party transactions) cannot exceed 50% of total revenue.
  5. The company is not a financial institution (bank, insurer, credit union, etc.).
  6. The company does not prepare financial statements under International Accounting Standards (IAS/IFRS).
  7. Filing a notification with the head of the tax office about choosing Estonian CIT (by the end of the first month of the tax year in which the company wishes to apply the lump-sum tax).

Estonian CIT Rates

| Taxpayer status | Lump-sum rate | |---|---| | Small taxpayer (revenue up to 2 million EUR) | 10% | | Other taxpayers | 20% |

These rates apply to income from distributed profit (dividends) and income from profit allocated to cover losses.

Effective Combined Tax Rate

When dividends are paid, the shareholder additionally pays dividend tax (PIT at 19%). However, thanks to a mechanism reducing the PIT by a portion of the CIT already paid, the total effective tax burden is:

  • Small taxpayer: approximately 20% (instead of approximately 26.3% under standard CIT),
  • Other taxpayers: approximately 25% (instead of approximately 34.4% under standard CIT).

This represents significant savings compared to the traditional CIT + dividend model.

What is Taxed?

Under Estonian CIT, the following are subject to taxation:

  • Distributed profit -- dividends or advance dividends paid to shareholders.
  • Profit allocated to cover losses -- if losses arose in the period before switching to Estonian CIT.
  • Hidden profit -- benefits provided to shareholders, their close relatives, or related entities that exceed market conditions (e.g., inflated shareholder remuneration, free use of company assets, loans on non-market terms).
  • Non-business expenditure -- spending without business justification.
  • Changes in asset values -- upon reorganization, liquidation, or transition to another form of taxation.

Hidden Profits -- What to Watch Out For

The category of "hidden profits" is one of the most important (and most challenging) aspects of Estonian CIT. The following may be treated as hidden profit:

  • shareholder-manager remuneration exceeding market rates,
  • property rental from a shareholder at inflated prices,
  • loans from the company to shareholders on non-market terms,
  • free-of-charge benefits for shareholders (e.g., private use of a company car without payment),
  • gifts to shareholders or their families.

Tax authorities examine whether transactions between the company and shareholders take place on market terms (arm's length principle). Therefore, proper documentation and valuation of such transactions is crucial.

Practical Example

A limited liability company (small taxpayer) earns net profit of 500,000 PLN per year.

Scenario 1: Standard CIT

  • CIT at 9%: 45,000 PLN
  • Profit for distribution: 455,000 PLN
  • PIT on dividend at 19%: 86,450 PLN
  • Total tax: 131,450 PLN (26.3%)

Scenario 2: Estonian CIT -- profit reinvested

  • CIT: 0 PLN (no profit distribution)
  • PIT: 0 PLN
  • Total tax: 0 PLN (until distribution)

Scenario 3: Estonian CIT -- full distribution

  • Lump-sum at 10%: 50,000 PLN
  • PIT on dividend (after reduction): approximately 50,000 PLN
  • Total tax: approximately 100,000 PLN (20%)

The difference is particularly striking when the company reinvests profits -- under Estonian CIT, the tax is 0 PLN until distribution.

Advantages of Estonian CIT

  • Tax deferral -- no tax until profit distribution, supporting reinvestment and business growth.
  • Lower combined taxation -- effective rate of 20--25% instead of 26--34%.
  • Simplified accounting -- no need to maintain detailed tax cost records (taxable income is not calculated in the traditional way).
  • No advance CIT payments -- tax is due only upon profit distribution.
  • Incentive to reinvest -- the model naturally encourages allocating profits to business development.

Disadvantages and Risks

  • Hidden profits -- risk of taxation on transactions with shareholders, even if they are not formally dividends.
  • Entity restrictions -- shareholders can only be natural persons; the company cannot hold shares in other entities.
  • Employment requirement -- minimum 3 employees on employment contracts.
  • No tax depreciation -- traditional depreciation deductions are not applied under Estonian CIT.
  • Exit taxation -- when leaving Estonian CIT, retained profits must be settled.
  • Limited optimization options -- many reliefs available under standard CIT are not applicable (e.g., R&D relief, IP Box).

How to Switch to Estonian CIT?

  1. Verify that the company meets all conditions (legal form, ownership structure, employment, no shares in other entities).
  2. Prepare information on revenue, costs, and profits from previous years (for potential taxation of differences).
  3. File notification ZAW-RD with the head of the tax office by the end of the first month of the tax year.
  4. Adapt the accounting policy and shareholder payout processes.

Estonian CIT is applied for a minimum period of 4 tax years (with the option to extend for subsequent 4-year periods).

Summary

Estonian CIT is an attractive option for companies that reinvest profits, offering significant tax deferral and reduction. It is particularly beneficial for fast-growing businesses that allocate profits to investments rather than paying dividends. However, it requires careful management of transactions with shareholders and compliance with restrictive conditions. Before making a decision, it is worth analyzing whether the company form and ownership structure allow for this solution.
