LLC or Simple Joint-Stock Company? A guide for entrepreneurs
20 Feb 2026
Choosing a legal form is one of the first and most important decisions when starting a business. In the Polish legal system, alongside the established limited liability company (LLC, sp. z o.o.) there is the Simple Joint-Stock Company (PSA).
Both aim to limit shareholders’ liability, but internal mechanisms differ. As an accounting firm we settle both types daily – here is a comparison of key differences.
Capital at the start
This is the most often cited difference.
- LLC: Minimum share capital of PLN 5,000. The full amount must be paid in before registration.
PSA: A symbolic PLN 1 of share capital suffices. Interestingly, in a PSA the contribution can also be work or services for the company, which is not allowed in a classic LLC.
Flexibility and management
The PSA was designed for startups and innovative projects where structure must be dynamic.
- In an LLC there is a traditional split between the management board and the general meeting (optionally a supervisory board).
In a PSA you can appoint a board of directors combining executive and supervisory functions – known from Anglo-Saxon systems and speeding up decisions.
Transfer of shares and stock
- LLC: Transfer of shares requires written form with notarially certified signatures – notary visit and extra costs.
PSA: The register of shareholders is electronic (e.g. via an investment firm or notary). Transfer of shares is simpler and can be done by e-mail or digital platforms, which helps attract investors.
Running costs
- LLC: remember fixed costs such as office rent and accounting services.
PSA: the same fixed costs, plus you must maintain a register of shareholders – about PLN 1,200 per year.
Comparison at a glance
What should you remember?
From an accounting perspective, both entities keep full books and are CIT taxpayers. The choice does not drastically change day-to-day documentation for the tax office, but it matters greatly for ownership structure and planned growth.
