Knowledge you can use
in your company.
Short guides and explanations of topics boards and partners ask about most often — at launch and during the year.
- Guide GDPR in Poland: what every company needs to implement GDPR is not a one-off privacy policy or a file of consent forms. A company operating in Poland must be able to explain and demonstrate how it collects, uses, shares, protects and deletes personal data — from recruitment and payroll to customer service, accounting, marketing and cloud systems.
- Guide Corporate income tax (CIT) in Poland: rates, deadlines and company obligations Polish corporate income tax is not simply ‘19% of company revenue’. The taxpayer, tax residence, revenue timing, deductible costs, source of income and available regime all matter. For a company operating in Poland, CIT is a year-round accounting and control process, not only the annual CIT-8 return.
- Guide Sole proprietorship in Poland: registration, taxes and ZUS A Polish sole proprietorship — jednoosobowa działalność gospodarcza, commonly shortened to JDG — is a business carried on by an individual under an entry in CEIDG. It is quick and free to register, but it is not a separate legal person: the owner earns the income, pays PIT and ZUS, and is personally liable for the business.
- Guide Limited partnership in Poland: partners, liability and taxes A Polish limited partnership — spółka komandytowa or sp.k. — is a commercial partnership with at least one general partner whose liability is unlimited and at least one limited partner whose liability to creditors is restricted under statutory rules. It has no legal personality, but it can own assets, enter into contracts, employ people and sue or be sued in its own name.
- Guide Limited joint-stock partnership in Poland: shares, liability and tax A Polish limited joint-stock partnership — spółka komandytowo-akcyjna or S.K.A. — is a commercial partnership that operates an enterprise in its own name. It must have at least one general partner with unlimited liability and at least one shareholder. The form combines partnership management with share-based capital, but it is neither a limited partnership nor an ordinary joint-stock company.
- Guide Joint-stock company in Poland: capital, shares and governance A Polish joint-stock company — spółka akcyjna, abbreviated S.A. — is a capital company with legal personality, shares and a mandatory management board, supervisory board and general meeting. It can support a sizeable or investment-led venture, but the legal form is not reserved for large businesses and does not by itself make the company public or listed. This guide explains the rules verified for 19 August 2026.
