A simple joint-stock company (j. s. a.) is a capital company aimed mainly at startups. Share capital starts at €1, even a single individual can establish it, and it issues shares, including shares with special profit, voting or information rights. The founding document must take the form of a notarial deed or a document authorised by an attorney, the capital is paid up before incorporation and the shares are issued through the Central Securities Depository.
Who is the simple joint-stock company for?
The simple joint-stock company is a separate legal form, rather than a subtype of the ordinary joint-stock company. Slovak law introduced it in 2017 to support the startup ecosystem. Its capital is divided into shares and must be at least €1 (Section 220t(2) of the Commercial Code), compared with €5,000 for an s.r.o. and €25,000 for an ordinary joint-stock company. Its business name includes “j. s. a.” (Section 220h(2)). One or more persons may establish it; unlike an ordinary joint-stock company, it can be founded by a single individual.
What does formation require?
A low entry cost does not mean an informal process:
- The agreement or deed of foundation must take the form of a notarial deed or a document authorised by an attorney and include the articles of association (Section 57(1) and (3) and Section 220u(2)). The special rule requiring a notarial deed for a j. s. a. was removed with effect from 17 August 2026.
- The company cannot be founded through an invitation to subscribe for shares. All capital must be subscribed and all contributions paid before incorporation (Section 220t(3) and (4)).
- Shares must be book-entry registered shares (Section 220i(1)), issued through the Central Securities Depository. An incomplete share issue is the most common practical mistake: the company is registered but has never properly issued its shares.
How is it more flexible than an s.r.o. or a.s.?
Alongside ordinary shares, a j. s. a. can issue shares with special rights: different shares of profits or liquidation proceeds, different voting entitlements or information rights, and even non-voting shares (Section 220i(3) and (5)). The articles may restrict or exclude transferability altogether (Section 220k). Where transferability is excluded, however, a shareholder acquires a right, not subject to limitation, to require the company to buy the shares four years after the issue price was paid (Section 220l).
For investor relations, tag-along, drag-along and shoot-out arrangements have express statutory rules for a j. s. a. Registered tag-along and drag-along rights are not subject to limitation and bind the shareholder’s legal successors (Section 220w). See our shareholders’ agreements service.
What to consider in advance
A j. s. a. may be established afresh or created by changing the legal form of an s.r.o. or ordinary joint-stock company. It may itself change its legal form to an s.r.o. or ordinary joint-stock company (Section 105 of Act No. 309/2023 Coll.). The change requires a conversion project and approval under the Transformations Act. Shares with special rights can therefore also be introduced for an existing company. Our simple joint-stock company formation service covers the process and comparison with forming an s.r.o..
