With almost 37 million inhabitants, Poland is the largest market in Central and Eastern Europe and part of many German companies‘ supply chains. For tax purposes, the country offers three routes to a low burden depending on size and business model: 9% for small companies, the Ryczałt lump-sum tax – usually called “Estonian CIT” in Poland – with tax only on distribution, and an IP Box with 5% on income from in-house intellectual property. Company formation in Poland therefore works best when this choice is made before formation.
Three routes to low tax
Standard corporate tax is 19%. Alongside it, three special routes are available, some of which can be combined:
| Model | Rate | For whom |
|---|---|---|
| Small taxpayers | 9% | prior-year turnover up to €2 million, new companies in year one |
| Lump-sum tax (Ryczałt) | 0% while retained, 10% or 20% on distribution | companies that reinvest profits |
| IP Box | 5% | income from self-developed intellectual property |
About the name: officially, the model is called “ryczałt od dochodów spółek”, a lump-sum tax on company income. In Poland it is colloquially known as “Estonian CIT” because, following the Estonian example, it taxes profits only on distribution – but it is a purely Polish regime for Polish companies. Under the Ryczałt, including the tax at shareholder level, small companies face an overall burden of around 18% instead of around 26% under standard taxation. Taxes are administered by the Polish tax administration.
IP Box: 5% on software
The Polish IP Box taxes income from qualifying intellectual property at 5%. This includes in particular copyrighted software and patents that the company has developed or improved itself. A separate record of development costs and qualifying income is required.
For software companies with a development team in Poland, the rate can bring the overall burden well below that of the Ryczałt. Anyone planning company formation in Poland with software development on site should therefore set up the accounting for the IP Box from the outset.
E-invoicing via KSeF
Since 2026, e-invoicing has been mandatory in Poland; invoices are issued via the state KSeF system: for large companies since 1 February, for all other VAT-registered companies since 1 April 2026; transitional periods apply to micro-entrepreneurs. Invoices are issued in real time through the system and archived there for ten years.
For founders, this means accounting and invoicing software must be KSeF-compatible from the start. The company reports VAT monthly via the electronic JPK_V7M file by the 25th of the following month.
Legal form and annual accounts
The usual legal form is the Sp. z o.o., the Polish counterpart to the German GmbH, with a minimum capital of PLN 5,000 (about €1,100). Shareholders and managers can be of any nationality. For larger ventures there is the joint-stock company S.A. with PLN 100,000 of share capital.
The company approves its annual accounts within six months of the end of the financial year and files them with the National Court Register (KRS) within 15 days.
Online or notarised
Company formation in Poland offers two routes – online via the S24 procedure with a model contract, or traditionally with notarised articles. The process follows these steps:
- Choose the route: S24 for standard cases, a notary for individual articles.
- Articles of association: seat, capital, management and activity codes.
- Pay in the capital: at least PLN 5,000.
- Registration in the KRS: the tax number (NIP) and statistical number (REGON) are issued automatically.
- Tax model and VAT: election of the Ryczałt or IP Box and VAT registration.
Via S24, registration is often completed within a few days.

As of 2026. Bookkeeping and filings are usually handled by specialised accountants in the target country.
Is Poland right for you?
Poland convinces above all where supply chains and markets lie in Central and Eastern Europe or where in-house software is developed. Whether the location is right for you:
Suitable for
- Manufacturing and logistics businesses close to Germany
- Software firms with their own intellectual property
- Small companies with turnover below €2 million
- Companies that reinvest profits and grow
Less suitable for
- Founders who want to avoid electronic invoicing
- Holdings that only manage passive income
- Ventures with no link to Central and Eastern Europe
- Entrepreneurs expecting a fully English-language administration
With the lowest corporate tax rate in the EU, Hungary is an alternative in the region; the original Estonian model is found in Estonia.
