What are the rates of Corporate Income Tax in Poland? 

Tax laws in Poland define specific CIT rates depending on revenue thresholds, the nature of the income (operating vs. capital gains), and chosen taxation models. 

The 19% Standard Corporate Tax 

As a rule, Polish tax residents’ taxable income is subject to the default 19% Corporate Income Tax. This standard rate applies to most medium and large enterprises, as well as to all income classified as capital gains, regardless of the company’s size. 

The 9% Reduced CIT Rate 

A preferential 9% CIT rate has been introduced for operating revenues (incomes other than capital gains) to support smaller businesses. Taxpayers can apply this reduced rate if: 

● They hold the status of a small taxpayer, meaning their gross sales revenue in the previous year did not exceed the PLN equivalent of EUR 2 million (converted using the NBP exchange rate from the first working day of October). 

● For applying the 9% rate in the current year, current revenues also must not exceed the EUR 2 million threshold (converted using the NBP rate from the first working day of that tax year). 

● Note for 2026: The threshold must be pro-rated for tax years that are shorter or longer than 12 months. New businesses commencing activity can use this rate in their first year without prior-year limits.

How does the Estonian CIT model work? 

The “Estonian CIT” (Ryczałt od dochodów spółek) is a modern taxation model focused on the moment of tax payment rather than a standard monthly effective tax rate. Under this regime, advance monthly tax payments are abolished. CIT is paid only when the company’s profit is distributed (e.g., as a dividend). As a result, during the profit retention period, the payable tax is exactly 0%. 

Effective tax rates upon distribution 

When the company finally decides to distribute profits, the combined effective tax rate (comprising both the corporate tax on the company’s profit and the dividend tax paid by the shareholder) is significantly lower than under the classic CIT model: 

● For small taxpayers: The effective total tax burden is only 20% (compared to 26.29% under standard rules). 

● For standard taxpayers: The effective total tax burden is 25% (compared to 34.39% under standard rules). 

Minimum Taxes and Loss Regulations (Compliance 2026) 

The Polish tax system has introduced specialized mechanisms to prevent tax avoidance and align with global OECD standards. 

Minimum Income Tax (Podatek Minimalny) 

The general Minimum Income Tax targets companies reporting artificial losses. It applies to corporate taxpayers who report a tax loss for the year or whose operational profitability ratio is 2% or lower. Additionally, the Corporate Income Tax Act maintains a minimum CIT on commercial real estate properties (0.035% monthly for buildings with an initial value exceeding PLN 10 million).

Rules for Tax Losses 

Ordinary tax losses in Poland may be carried forward and set off against income over a period of 5 years. However, in each year, a standard loss relief claim is limited to 50% of each carried-forward loss generated in the prior 5 years. Alternatively, taxpayers have the right to a one-time deduction of up to PLN 5 million of the loss in a single tax year. Losses may be forfeited if a company undergoes specific legal restructuring. 

Pillar Two and JPK_CIT (Digital Reporting) 

For tax years beginning in 2025 and 2026, large taxpayers are subject to major compliance shifts: 

● Pillar Two: Poland has implemented the Global Minimum Tax, ensuring that large multinational groups maintain an effective tax rate of at least 15%. ● JPK_CIT: Mandatory electronic submission of accounting books (JPK_KR_PD) and fixed assets registers (JPK_ST_KR) is now required, fundamentally changing how the tax office audits corporate accounts. 

FAQ About Corporate Income Tax in Poland 

What is the default rate of Corporate Income Tax in Poland? 

The standard CIT rate is 19% in Poland. However, if your company qualifies as a small taxpayer (with revenues up to EUR 2 million) or is a newly established start-up, a preferential 9% CIT rate may apply to your non-capital income.

Are equity contributions subject to Corporate Income Tax in Poland? 

No. Cash contributions made to a Polish company by a shareholder (e.g., increasing the share capital) are not subject to Corporate Income Tax for either the Polish company or the shareholder. 

What is the capital gains tax in Poland? 

There is no separate capital gains tax regime for corporations in Poland. Capital gains are strictly taxed under the Corporate Income Tax act at the standard rate of 19%, even if the company qualifies for the 9% rate on its operational income. 

Can tax losses in Poland be carried forward?

Yes. As a general rule, corporate tax losses in Poland may be carried forward and set off against future income over a period of 5 consecutive years, subject to a 50% annual deduction limit, or a one-time deduction of up to PLN 5 million.
