Estonian CIT (in Polish, estonski CIT or ryczalt od dochodow spolek) is a lump-sum form of corporate income tax in Poland that defers taxation until profits are distributed to shareholders. Instead of paying tax on accounting profit every year, a company pays tax only when it pays out a dividend. This makes Estonian CIT a powerful tool for businesses that reinvest their earnings.
How does Estonian CIT work?
Under the standard Polish corporate tax system, a company pays CIT on its taxable income each year regardless of whether the profit stays in the business. Under Estonian CIT, the tax point shifts: as long as profit is retained and reinvested, no corporate tax is due. Tax is triggered only when profit is distributed, for example as a dividend to shareholders.
Who can use Estonian CIT?
The regime is available to limited liability companies, joint-stock companies, simple joint-stock companies and certain partnerships, provided they meet several conditions:
- Shareholders must be only natural persons.
- The company must not hold shares in other entities.
- Passive income (interest, royalties, etc.) must not exceed 50% of total revenue.
- The company must employ a minimum number of staff, with reliefs for small and new businesses.
What are the effective tax rates?
The headline rates depend on company size. A small taxpayer pays 10% lump-sum CIT, while a larger company pays 20%. However, the real advantage comes from how the rate combines with the shareholder dividend tax. Thanks to a deduction mechanism, the combined effective rate on distributed profit is roughly 20% for small taxpayers and 25% for larger ones — lower than the typical combined burden under standard CIT plus dividend tax.
Worked example
A small company earns 500,000 PLN of profit and decides to distribute all of it.
- Estonian CIT at 10%: 50,000 PLN
- Distributable amount: 450,000 PLN
- Shareholder dividend tax of 19%, reduced by 90% of the CIT paid, yields an effective shareholder tax of about 40,500 PLN
- Total tax burden: about 90,000 PLN, or roughly 18% of profit
Under standard CIT (9% for small taxpayers) plus a full 19% dividend tax, the combined burden would be higher and, crucially, the corporate part would be due every year rather than only on distribution.
Main advantages and drawbacks
The biggest advantage is cash-flow deferral: companies that reinvest pay no corporate tax until they take money out. Drawbacks include strict eligibility rules, the loss of certain deductions and reliefs available under standard CIT, and additional reporting obligations. Estonian CIT suits growing, profit-reinvesting companies far better than those that distribute everything immediately.
