A Joint Stock Company — known in Bulgaria as an AD (two or more shareholders) or EAD (single shareholder) — is the most sophisticated corporate structure available under Bulgarian law, best suited for larger businesses, companies planning to raise external capital, or ventures that require a formal share structure with tradeable securities.
What is a Joint Stock Company?
An AD or EAD is a capital company in which all shareholders bear limited liability — each is liable only to the extent of their capital contribution. The total capital is divided into shares, and the sum of all shareholders’ shares constitutes the registered share capital. The minimum share capital required is EUR 25,565 — significantly higher than the EUR 1.00 minimum for an OOD or EOOD, reflecting the more formal nature of this structure.
Key features
Tradeable shares. Unlike shares in a Bulgarian OOD, shares in an AD or EAD can be freely traded, making this structure appropriate for businesses anticipating investment rounds, stock exchange listings, or broad shareholder participation.
Access to external capital. A Joint Stock Company can raise additional financing by issuing obligations (bonds) — a mechanism not available to limited liability companies, giving the AD a significant advantage in accessing capital markets.
Profit distribution. Shareholders are entitled to participate in profit distribution in proportion to their shareholding, as well as to other benefits defined in the articles of association.
Company name. The name must include “AD” for two or more shareholders, or “EAD” for a single shareholder.
Tax treatment
All Bulgarian Joint Stock Companies are subject to the flat 10% corporate income tax on net profit — one of the lowest rates in the EU. Profit distributions are subject to a 5% dividend withholding tax. Bulgaria’s network of over 70 Double Taxation Treaties may reduce or eliminate withholding taxes on cross-border dividend payments.
Is an AD the right structure for you?
For most foreign investors, an OOD or EOOD offers simpler administration, lower capital requirements, and equivalent tax efficiency. The AD or EAD is the right choice when the business genuinely requires a formal share structure, plans to access capital markets, or anticipates a large or evolving shareholder base.
