Branch Office in Bulgaria: Registration, Requirements and Foreign Company Setup

A Bulgarian branch office lets a foreign company establish a formal presence in Bulgaria without creating a separate EOOD or OOD entity. It is not a casual shortcut. A branch is an extension of the parent company — which means Bulgarian accounting, tax, VAT, and liability obligations follow directly, whether you plan for them or not.

Legal status

Not a separate legal entity

A Bulgarian branch has a BULSTAT/EIK number and a registered seat, but it is not an EOOD or OOD. It is the parent company operating in Bulgaria under a local registration.

Liability

Parent company stands behind all obligations

If the branch signs a lease, hires staff, or receives a tax reassessment, the parent company is directly liable. This is the sentence most founders underestimate.

Compliance

Real accounting and tax obligations apply

A branch must keep Bulgarian accounting records, file tax returns, handle VAT where applicable, and meet payroll reporting requirements if staff are employed locally.

Structure choice

Branch vs EOOD/OOD vs representative office

The correct structure depends on your activity, liability tolerance, and whether you need ring-fenced risk, local investors, or purely non-commercial liaison. Bulgarian.LLC scopes this first.

How Bulgarian.LLC charges for branch office work

Branch office basic assistance

€350 starting from

Basic support, initial review, setup guidance, or simple document handling for straightforward cases. Entry point for foreign companies that need a first professional look at their situation before committing to a full registration process.

Full branch registration support

Quoted after review

Full registration support: parent company document coordination, certified Bulgarian translations, apostilles or legalization, Commercial Register filing, registered address, tax and VAT registration, and post-registration setup. Price depends on jurisdiction, document complexity, and what is actually required.

Pricing note: €1,500 is the starting point for basic branch office assistance or an initial document review. Full branch registration involves apostilles, certified translations, Commercial Register filings, and often tax and VAT setup — these are quoted after we review the parent company documents and the actual requirements of the case. Transparency before commitment.

Branch office registration: step by step

1 Suitability check — branch, EOOD/OOD, or representative office?
Before any document preparation, we establish whether a branch is actually the right structure. A branch fits when the parent company wants direct operational control, its own trade name in Bulgaria, and is comfortable with full parent-level liability. An EOOD or OOD fits when liability ring-fencing matters, outside investors or local financing are planned, or the Bulgarian unit needs genuine standalone governance. A representative office fits only for non-commercial liaison and promotion with no revenue-generating activity. Getting this wrong is expensive — not because of the registration cost, but because unwinding the wrong structure takes time, money, and credibility.
2 Parent company document review
Branch registration lives or dies on parent company paperwork. The Bulgarian Commercial Register requires proof that the parent company exists and is in good standing, plus evidence that it has formally resolved to open a Bulgarian branch and appoint a manager. Depending on the parent’s jurisdiction — EU, UK, US, offshore — this may mean a simple registry extract, or it may require notarized resolutions, director certificates, and constitutional documents. We review the parent company’s corporate file before quoting full support, because the jurisdiction dictates the document path.
3 Branch name, registered address, activity scope, and manager powers
Four concrete decisions must be locked before filing: the exact branch trade name in Bulgarian (including whether to append “клон” notation in local documents), the registered address where statutory mail and NRA communications will land, the scope of business activity, and the manager’s signing authority — specifically whether they sign alone, in combination, or within a defined threshold. Vagueness on any of these is where disputes with banks, landlords, and counterparties originate. We help define each element in terms Bulgarian institutions accept without question.
4 Apostille or legalization and certified Bulgarian translations
All parent company documents must be legalized for use in Bulgaria and then translated into Bulgarian by a certified translator. If the parent’s country is part of the Hague Apostille Convention, the apostille route applies. If not, consular legalization is required — which has its own timeline, fees, and sequencing that cannot be rushed. Translation errors are the hidden killer: a manager’s name spelled two ways, a corporate form rendered with an inconsistent legal term, or an address with the wrong district notation can trigger a refusal and cost a week. We coordinate translations and apostilles and run a consistency check across every document before filing.
5 Commercial Register filing preparation and submission
The branch is registered with the Registry Agency in the Bulgarian Commercial Register, typically using the A8 application for a foreign branch, supported by parent company extracts, resolutions, manager consents and declarations, and proof of the registered address. The registry is procedurally strict: refusals for format issues — not substance — are common when documents are prepared without local experience. Once the application package is correctly assembled, the registry stage is often processed within a few business days. The hidden timeline is always document preparation, not the registry itself.
6 Post-registration: accounting, tax, VAT, payroll, and banking
Registration is the beginning, not the end. The branch must maintain Bulgarian double-entry accounting records for the local activity, prepare financial statements, and meet National Revenue Agency reporting obligations. If the branch makes taxable supplies exceeding the mandatory threshold, VAT registration is required — bringing monthly VAT returns, VIES declarations where relevant, and audit-ready invoice documentation. If employees are hired in Bulgaria, payroll reporting and social security compliance apply immediately. Banking setup requires AML and KYC documentation for the branch, the parent company, and the ultimate beneficial owner chain. Bulgarian.LLC coordinates all of this with the accounting and tax professionals who handle it daily.

Is a Bulgarian branch office the right structure for your company?

Most foreign founders arrive at this question thinking a branch is the “lightweight” option — no share capital, no new shareholder structure, no separate legal entity to explain to group stakeholders. That instinct is partly right and partly a trap. A branch can be the efficient, direct path to a formal Bulgarian presence. It can also be the wrong move if your Bulgarian activity carries meaningful risk, needs outside investment, or will operate as a standalone unit.

Bulgarian.LLC starts with a suitability check before recommending any structure. The goal is to understand the parent company’s activity, risk tolerance, banking requirements, and the realistic accounting and tax footprint before committing to a registration path.

When a branch fits well

A Bulgarian branch tends to fit when the parent company is already operational, already banked, and wants Bulgaria as an extension of existing group operations — not as a new “corporate child” with its own cap table and governance rituals. EU companies expanding sales, delivery, or contracting capacity while keeping group control centralized are the most common pattern.

A branch also fits when counterparties demand a Bulgarian presence on paper: clients who want a local merchant in the contract chain, landlords who need a Bulgarian seat for the lease, employees who want a local employer. Three signals point toward a branch almost every time:

  • You want operations in Bulgaria under the parent company’s trade name and history.
  • The parent company is already standing behind the Bulgarian obligations — so full liability is not a new risk, just a formalized one.
  • Profits will be reinvested or remitted to the parent without a dividend workflow, which matters for how repatriation is treated.

Remitting branch profits to the head office is generally not treated as a dividend under Bulgarian rules and is widely described as carrying no withholding tax on repatriation — one of the recurring reasons branches remain popular for “one balance sheet” groups. This treatment should still be verified against treaty positions and the parent jurisdiction’s permanent establishment rules, not taken as a universal given.

When a subsidiary fits better

If liability ring-fencing is the priority, the answer is a subsidiary. A Bulgarian branch is an extension of the parent — which means the parent is the obvious target in any dispute, claim, or tax reassessment. When the Bulgarian activity can generate contractual disputes, product liability, leasing risk, or regulatory exposure, a branch is a little too honest about who is ultimately responsible.

Subsidiaries — typically an EOOD (single-member) or OOD (multi-member limited liability company) — also fit when the Bulgarian unit will have outside investors, option pools, local financing, or a management team that needs defined authority without escalating every significant decision to headquarters. Banking can also tip the decision: a branch is not automatically easier to bank than a subsidiary. Banks want to understand the UBO chain regardless of structure, and they will ask the Bulgarian manager to explain group flows in plain terms while reviewing parent company documents that were never designed for Bulgarian compliance officers.

When a representative office fits

A trade representative office is the structure for “presence without commercial activity.” That is the essential distinction. No revenue-generating contracting. No invoicing Bulgarian clients. No local sales contracts. Representative offices are practical for market research, liaison activity, demonstrations, and relationship-building — when you need staff on the ground without conducting commercial activity under Bulgarian law.

The trap is using a representative office quietly as a sales entity. If the office is invoicing, collecting payments, hiring staff to deliver services, or acting as a permanent establishment in any practical sense, it has drifted into branch and tax territory regardless of what it was registered as.

What the legal and liability consequences actually mean

A Bulgarian branch is registered in the Commercial Register with a BULSTAT/EIK identifier and a registered seat. It can appear entirely “local” to clients, landlords, and counterparties. It is still not a separate legal entity under Bulgarian commercial law — and that distinction affects every operational and legal decision the branch makes.

Obligations of the branch are obligations of the parent

This is the sentence to sit with before choosing a branch structure: obligations of the Bulgarian branch are obligations of the parent company. A signed lease, hired staff, an NRA tax reassessment — all of these trace back to the parent company. Large groups routinely operate this way across multiple jurisdictions with full awareness of the exposure. The risk is when a mid-size company treats a branch as a “trial run,” signs real commercial commitments in Bulgaria, and then finds that the trial is legally indistinguishable from the parent company acting directly.

Branch manager authority must be defined precisely

The branch manager is a real legal actor. Their authority is registered in the Commercial Register and governs what they can commit to on behalf of the parent. If two people must sign, that needs to be stated clearly. If the manager can sign alone up to a defined threshold, the threshold needs to be specified in terms Bulgarian banks, landlords, and counterparties recognize without needing to call headquarters. Vagueness in manager powers is where disputes originate, and where foreign groups sometimes find that their elegant internal governance rules are unreadable locally.

The parent company documents are the critical path

Foreign founders typically focus on the Bulgarian filing and assume the parent company documents are straightforward. They are often not. The Bulgarian Commercial Register requires specific corporate extracts, board or shareholder resolutions authorizing the branch, and manager appointment documentation — all in formats the Registry Agency accepts, legalized for use in Bulgaria, and translated into Bulgarian by certified translators.

The exact document bundle varies significantly by jurisdiction. A company incorporated in Germany, the Netherlands, England, Delaware, or an offshore jurisdiction each speaks a different dialect of corporate evidence. This is why Bulgarian.LLC reviews the parent company’s situation before quoting full registration support. The jurisdiction determines the legalization route, the document requirements, and the realistic timeline.

Apostille and legalization: where timelines actually go wrong

Founders consistently underestimate the apostille and legalization step. The Bulgarian registry filing fee is rarely the problem. The legalizations are. If the parent company’s jurisdiction is part of the Hague Apostille Convention, the apostille route applies. If not, consular legalization is required — with its own fees, sequencing, and clock that cannot be compressed by enthusiasm or urgency.

Common delays that look small and cost weeks: a parent company certificate older than what the Registry Agency accepts as current; an apostille that is missing entirely; a translation with inconsistent corporate identifiers across pages; a manager who cannot sign declarations in the required form because they are traveling. Each one is preventable with proper sequencing. None of them are recoverable at the last minute.

Tax, VAT, and accounting — what a branch actually commits you to

Bulgaria’s corporate income tax rate is a flat 10%. A branch, as a taxable presence in Bulgaria, is typically subject to Bulgarian corporate income tax on profits attributable to the Bulgarian activity. This means defensible cost allocation, clean accounting for the local activity, and transfer pricing logic where the parent company has significant intercompany transactions with the branch.

VAT is a separate threshold question. If the branch makes taxable supplies in Bulgaria and crosses the mandatory registration threshold, VAT registration is required — bringing monthly VAT returns, VIES declarations where relevant, and audit-ready invoice documentation as a recurring operational commitment. Voluntary early VAT registration sometimes makes sense for input VAT recovery reasons; sometimes it creates unnecessary compliance overhead. The correct answer depends on the branch’s client base, transaction structure, and whether counterparties require VAT invoices.

If the branch employs staff in Bulgaria, payroll compliance, social security contributions, monthly NRA payroll reporting, and occupational safety obligations apply from the first hire. None of these are optional. Missed filings create penalties that compound, complicate banking, and create administrative noise that interferes with everything else the business is trying to do.

A branch that is correctly registered but operationally unmanaged is not a market entry. It is a liability in waiting. Bulgarian.LLC coordinates post-registration accounting, tax, VAT, and payroll with professionals who treat this as a compliance discipline, not a side task.

Branch office vs EOOD/OOD vs representative office

Criterion Branch office EOOD / OOD subsidiary Representative office
Legal entity status Extension of parent company — not a separate legal entity Separate Bulgarian legal entity with its own balance sheet Not a legal entity; not permitted to conduct commercial activity
Liability Parent company is fully liable for all branch obligations Liability limited to the subsidiary, with standard corporate caveats Parent exposure depends on actual conduct; should be non-commercial
Commercial activity Full commercial activity permitted — invoicing, contracting, delivery Full commercial activity permitted Not permitted — liaison, promotion, and research only
Parent company control Centralized — branch operates under parent’s name and governance Separate governance; subsidiary has its own director and board authority Centralized; representative office has no independent commercial authority
Accounting Bulgarian double-entry bookkeeping, local financial reporting required Bulgarian double-entry bookkeeping, local financial reporting required Lighter administrative duties, but still requires proper recordkeeping
VAT Registration required when taxable supplies exceed the threshold Registration required when taxable supplies exceed the threshold Typically not applicable if no commercial activity is conducted
Profit repatriation Remittance to head office — generally described as no withholding tax Dividends to shareholder — withholding tax may apply depending on treaty No profits if operated correctly as a non-commercial entity
Banking Possible, but requires full UBO chain and parent company documentation Standard Bulgarian business banking — still requires UBO documentation Limited banking needs; some banks will open accounts for representative offices
Best use case EU or established group wanting direct Bulgarian presence under the parent brand with centralized control Risk isolation, outside investors, independent local management, local financing Non-commercial market research, promotion, and liaison before full commitment

Branch office in Bulgaria — FAQ

Can a foreign company register a branch office in Bulgaria?
Yes. Foreign companies can register a branch in Bulgaria through the Bulgarian Commercial Register. The branch is not a separate legal entity — it is the foreign parent company registered and operating locally. The parent company retains full liability for branch obligations.
Is a Bulgarian branch office a separate legal entity?
No. A Bulgarian branch office is not a separate legal entity. It has a BULSTAT/EIK number and a registered seat, but it is an extension of the parent company under Bulgarian commercial law. This means the parent company is directly responsible for all obligations the branch incurs.
How long does Bulgaria branch office registration take?
Once the filing package is complete and correctly prepared, the Commercial Register typically processes a branch registration within a few business days. The real timeline depends on how quickly the parent company can obtain current corporate extracts, apostilles or legalizations, and certified Bulgarian translations. Document preparation is almost always the critical path, not the registry itself.
What documents are needed to register a branch in Bulgaria?
The core requirements are: a current parent company registration extract, constitutional documents, a resolution authorizing the branch and appointing a manager, branch registered address evidence, defined manager powers, and all of the above apostilled or legalized and translated into Bulgarian by certified translators. The exact document bundle depends on the parent company’s jurisdiction.
What is the difference between a branch office and a subsidiary in Bulgaria?
A branch is an extension of the parent company — not a separate legal entity. The parent company carries full liability for branch obligations. A subsidiary (EOOD or OOD) is a separate Bulgarian legal entity with its own balance sheet, governance, and liability ring-fence. A subsidiary is generally the right structure when liability isolation, outside investment, or local autonomy is important. A branch is better when the parent wants direct control and is comfortable bearing the Bulgarian obligations directly.
What is the difference between a branch office and a representative office in Bulgaria?
A branch can conduct full commercial activity — invoicing, contracting, delivering services, hiring employees — as an extension of the foreign company. A representative office is limited to non-commercial liaison, promotion, and market research. It cannot generate revenue or enter commercial contracts in Bulgaria. Using a representative office for commercial activity is a structural and tax risk.
Does a Bulgarian branch office need accounting?
Yes. A Bulgarian branch must maintain Bulgarian accounting records using double-entry bookkeeping, prepare financial statements for the local activity, and file tax returns with the National Revenue Agency. The branch does not escape local accounting obligations because the parent company files accounts in another country. Both accounting tracks run independently.
Can a branch office in Bulgaria register for VAT?
Yes. If the branch makes taxable supplies in Bulgaria and exceeds the mandatory VAT registration threshold, VAT registration is required. Voluntary VAT registration before the threshold is sometimes beneficial — depending on the client base, input VAT recovery position, and whether counterparties require VAT invoices. VAT registration brings monthly return obligations that must be managed consistently.
Can a branch office hire employees in Bulgaria?
Yes. A Bulgarian branch can employ staff locally. This triggers employment contract requirements, monthly payroll reporting, social security contributions, and occupational safety obligations under Bulgarian labour law. For non-EU staff, immigration and work permit planning must be coordinated early in the setup process — the process is document-heavy and not improvised.
How much does branch office registration in Bulgaria cost?
Bulgarian.LLC branch office support starts from €1,500 for basic assistance, an initial review, or simple document handling. Full branch registration support is quoted after reviewing the parent company documents and practical requirements — because the final cost depends on the parent jurisdiction, document complexity, apostille or legalization requirements, certified translations, Commercial Register filing, registered address, and whether tax, VAT, and accounting setup are included. Quoting before seeing the file would be guesswork.
Can Bulgarian.LLC help choose between a branch, EOOD/OOD, and representative office?
Yes — that is typically where the engagement starts. Bulgarian.LLC reviews the foreign company’s operational profile, risk tolerance, banking requirements, and planned activity in Bulgaria, then recommends the structure that actually fits. A branch is not always the right answer, and neither is a subsidiary. Getting the structure right at the start avoids the cost of correcting the wrong choice six months later.

Start your Bulgarian branch office setup from €1,500

Bulgarian.LLC can review your case, confirm whether a branch is the right structure, check your parent company documents, and explain the next steps clearly. Full branch registration support is scoped and quoted after the initial document review — because every parent company jurisdiction, document set, and business activity is different. Transparency first.
