Get to Know the Investor’s Tax Service Centre (COPI)
Planning an investment involves more than choosing the right location. It also means understanding the legal, tax and customs framework that supports business development.

One of the institutions worth knowing is the Investor’s Tax Service Centre (COPI), operating within the Polish Ministry of Finance. COPI provides investors with expert guidance on the Polish tax system, available tax reliefs and incentives, customs regulations, and the Investment Agreement – an instrument designed to increase tax certainty for major investment projects.
To help investors navigate these topics, COPI publishes a range of practical guides and brochures available free of charge.
Below you will find the latest publications prepared by COPI experts:
- Investor’s Tax Guide – Tax Reliefs and Incentives 2026
- Investor’s Guide – Customs Law 2026
- Investor’s Tax Service Centre – Information Brochure
- Why an Investment Agreement?
We encourage you to explore these materials and take advantage of the support available to companies investing and doing business in Poland.
