Quick Answer
An Ultimate Beneficial Owner (UBO) in Bulgaria is the natural person who ultimately owns or controls a company, typically through holding 25% or more of shares or voting rights, or exercising control by other means. UBO information must be declared in the Bulgarian Commercial Register and kept up to date under the Measures Against Money Laundering Act (MAMLA).

What Is an Ultimate Beneficial Owner (UBO)?
Under Bulgarian law, aligned with EU standards, an Ultimate Beneficial Owner (UBO) is always a natural person.
In most cases, a UBO is a person who:
- Directly or indirectly owns 25% or more of shares or capital;
- Holds 25% or more of voting rights;
- Exercises control through other means, such as shareholder agreements or dominant influence;
- Or, if no such person can be identified, the senior managing official (fallback rule).
Bulgarian law requires registered (not bearer) shares, ensuring that ultimate ownership can be traced through documented shareholding.
The 25% threshold is not limited to direct shareholding. Indirect ownership through one or more intermediary companies must also be assessed. For example, if an individual owns 60% of a foreign holding company that owns 50% of a Bulgarian subsidiary, that individual indirectly controls 30% of the Bulgarian entity and qualifies as a UBO.
Control without ownership can also be relevant. Voting agreements, contractual rights, or the ability to appoint or remove directors may create UBO status even below 25%.
If, after reasonable analysis, no individual meets the ownership or control tests, the company must declare its senior managing official (typically the managing director) as the UBO for regulatory purposes.
| Test Type | What Qualifies | Practical Example |
|---|---|---|
| Ownership Test | ≥25% direct or indirect ownership of shares/capital | 60% × 50% indirect chain = 30% → UBO |
| Control Test | Control via agreements, voting rights, dominant influence | Right to appoint majority of directors |
| Fallback Rule | No natural person identifiable under ownership/control tests | Managing director declared as UBO |
Why UBO Disclosure Exists?
The requirement to disclose the Ultimate Beneficial Owner Bulgaria framework stems from the EU’s anti-money laundering regime, particularly the 4th Anti-Money Laundering Directive (EU) 2015/849, implemented in Bulgaria through the Measures Against Money Laundering Act (MAMLA).
The objective is not administrative formality. It is to:
- Prevent misuse of corporate structures for money laundering or terrorist financing;
- Increase transparency within the EU financial system;
- Enable risk-based supervision;
- Support cross-border cooperation between regulators.
UBO disclosure reflects a governance principle: transparency about who ultimately stands behind a legal entity.
Ultimate Beneficial Owner (UBO) Bulgaria: Where Are UBOs Declared?
UBO information is declared through the Commercial Register maintained by the Bulgarian Registry Agency.
In specific cases involving trusts, fiduciary funds or similar foreign legal arrangements operating in Bulgaria, beneficial ownership information may be recorded in the BULSTAT Register, in accordance with Article 63 of the Measures Against Money Laundering Act.
For a broader overview of what company data is publicly accessible in Bulgaria, see our guide on Company Information in Bulgaria: What Is Public, What Is Not?
There is no separate standalone UBO register. UBO data forms part of the company’s official registration file.
The declaration is submitted by the company’s legal representative (usually the managing director). Responsibility remains with management.
Basic UBO identifying data is accessible through the Commercial Register portal. Access to full documentation or detailed filings typically requires authentication (for example via a Bulgarian Qualified Electronic Signature or equivalent tools).
Following EU case law (such as WM v Luxembourg) and recent amendments, the scope of public access may continue to evolve as EU harmonisation progresses.
Bulgaria also applies a discrepancy reporting mechanism. If an obliged entity (bank, auditor, notary, accountant, consultant) identifies inconsistencies between declared UBO data and due diligence findings, it must notify the Registry Agency. In certain cases, this notification must be made within 14 days of identifying the discrepancy.
Who Must Declare a UBO?
The obligation applies broadly to:
- EOOD (single-member limited liability companies)
- OOD (limited liability companies)
- AD (joint-stock companies)
- Foreign-owned Bulgarian subsidiaries
- Branches of foreign entities operating in Bulgaria, where registration obligations arise under the applicable transparency rules
- Group structures operating through Bulgarian legal entities
Where all shareholders are natural persons who are already publicly visible in the Commercial Register, and no additional indirect control exists, separate UBO disclosure may not be required beyond the registered ownership data.
Similarly, where a Bulgarian legal entity shareholder ultimately leads to a clearly identifiable natural person through existing public records, additional UBO registration may not be necessary. Each structure should nevertheless be assessed individually to confirm compliance.
Publicly listed companies on regulated markets subject to EU disclosure rules may qualify for exemptions where ownership transparency is already ensured. However, this requires formal assessment and does not automatically remove filing obligations.
Foreign shareholders must be declared if they ultimately meet the ownership or control criteria.
When Must UBO Information Be Updated?
UBO information must be accurate at all times.
Updates are required when:
- Shareholding changes;
- Indirect ownership changes;
- Control arrangements are amended;
- The corporate structure is reorganised;
- The fallback senior managing official is no longer correct.
The update must be filed without undue delay and, in practice, within 7 days of the change occurring, as applied by the Registry Agency.
Administrative sanctions under the Measures Against Money Laundering Act are structured and may vary depending on the nature of the violation, the type of entity involved, and whether the breach is repeated or systematic. The law provides for fines and property sanctions for both natural and legal persons, which can become significant in cases of serious or repeated non-compliance.
In severe or repeated breaches, sanctions for legal entities may reach substantially higher levels under MAMLA.
The key point is not the fine. It is the obligation to ensure the register reflects reality.
Common Mistakes and Misunderstandings
1. “The shareholder is automatically the UBO.”
Only shareholders meeting the ownership or control tests qualify.
2. Ignoring indirect ownership.
Multi-layer group structures frequently require deeper analysis.
3. Prematurely declaring management as UBO.
The fallback rule applies only after reasonable efforts to identify a qualifying natural person.
4. Forgetting updates after restructuring.
Changes in holding percentages or voting rights require reassessment.
5. Assuming the accountant handles it automatically.
Management remains legally responsible for declared information.
UBO analysis is a governance responsibility, not a clerical formality.
How UBO Connects to AML and KYC?
UBO declaration is directly linked to AML and KYC obligations. For a full overview of how the framework applies to businesses in Bulgaria, see our guide to Anti-Money Laundering in Bulgaria.
Banks and other obliged entities will cross-check UBO declarations independently as part of their KYC procedures in Bulgaria — a process that runs parallel to, and separately from, the Commercial Register filing obligation.
They routinely cross-check:
- Commercial Register data;
- Shareholder documentation;
- Group ownership charts;
- Identification documents;
- Source-of-funds assessments.
Discrepancies may trigger enhanced due diligence or onboarding delays.
Under MAMLA, certain obliged entities — including accountants and consultants — must notify the Registry Agency within 14 days if they identify a discrepancy between declared UBO information and data obtained during due diligence.
Accurate UBO declaration reduces compliance friction.
Practical Preparation Checklist
From a governance perspective, companies should:
- Maintain an updated ownership chart;
- Document indirect ownership chains clearly;
- Maintain supporting documentation, particularly for foreign ownership chains (e.g. shareholder extracts, constitutional documents, certified corporate records);
- Review UBO status after structural changes;
- Ensure updates are filed within the 7-day practice window.
Conclusion
Understanding the Ultimate Beneficial Owner (UBO) Bulgaria framework is part of responsible corporate governance. It reflects EU transparency standards and aligns with anti-money laundering supervision across the financial system.
Accurate UBO identification, proper documentation, and timely updates ensure that company records reflect economic reality. Where ownership chains involve multiple jurisdictions or layered structures, structured review is advisable. In such cases, a formal due diligence assessment can help clarify ownership, control relationships, and reporting obligations.
If your structure includes indirect holdings or cross-border elements, a professional review supports compliance and reduces unnecessary friction with banks and counterparties. For a tailored assessment, you may contact us.
Frequently Asked Questions
What is the UBO threshold in Bulgaria?
The standard threshold is 25% ownership or control. A natural person holding 25% or more of shares, voting rights, or exercising control by other means qualifies as a UBO. Indirect ownership through holding structures must also be included in the calculation.
What if no one owns 25% of the company?
If no natural person meets the ownership or control test, the company must declare its senior managing official (typically the managing director) as UBO under the fallback rule provided in MAMLA.
Are UBO details public in Bulgaria?
Basic UBO identifying data is available through the Commercial Register portal. Access to full documentation or detailed filings typically requires authentication. The scope of public access may evolve following EU case law and legislative updates.
Do foreign shareholders need to be declared as UBOs?
Yes. If a foreign individual ultimately owns or controls 25% or more of a Bulgarian company, directly or indirectly, they must be declared in the Commercial Register.
What are the fines for incorrect or missing UBO declaration?
Failure to request entry of required UBO data may result in an administrative fine of BGN 5,000 for individuals and property sanctions for legal entities. Continued non-compliance may trigger additional monthly penalties until the entry is requested.
