Branch vs Subsidiary Bulgaria 2026: Registration, Liability & Timelines

Branch vs subsidiary Bulgaria: quick comparison and TL;DR

The branch vs subsidiary Bulgaria decision shapes everything that follows for a foreign company entering the Bulgarian market, from liability and tax residence to banking, hiring and how quickly you can start trading. In 2026 this choice carries added weight because Bulgaria adopted the euro on 1 January 2026, which changes the mechanics of corporate banking, accounting and profit repatriation. Both routes are administered through the Bulgarian Commercial Register at the Registry Agency, but they produce very different legal and commercial outcomes. A branch is an extension of the foreign parent with no separate legal personality; a subsidiary is a distinct Bulgarian company.

This guide walks through each structure in practical detail, with document checklists, realistic timelines and a clear decision framework.

• Choose a branch when you want a lower-commitment presence for market testing, representation or a single line of activity closely tied to the parent.
• Choose a subsidiary when you need full trading capacity, local contracting, employment at scale and clear ring-fencing of liability.
• Liability differs sharply. A branch does not shield the parent; a subsidiary generally limits exposure to the Bulgarian company itself.
• 2026 euro adoption affects account currency, statement conventions and repatriation, factor it into your banking and treasury planning from day one.

What is a branch and what is a subsidiary in Bulgaria?

Understanding the branch vs subsidiary Bulgaria distinction starts with legal personality. Bulgarian company law, codified in the Commercial Act (Търговски закон) published in the State Gazette, treats these two structures fundamentally differently. A branch is legally part of the foreign company; a subsidiary is a separate Bulgarian legal person. That single difference cascades into contracting capacity, liability, tax treatment and governance.

Branch, legal nature, representation and tax registration

A branch (клон) of a foreign company is registered in the Commercial Register but does not acquire its own legal personality. It acts in the name and on the account of the foreign parent. Its key features include:

• No separate legal personality. The branch is an operational extension of the parent, which remains the contracting party and bearer of obligations.
• Local representation. A branch manager is appointed and registered, with authority to represent the branch in day-to-day dealings.
• Tax registration. Where the branch constitutes a permanent establishment, it must register with the National Revenue Agency and account for Bulgarian tax on its locally attributable profits.
• Separate accounting. The branch keeps its own books in Bulgarian and files locally, even though its results ultimately consolidate into the parent.

Subsidiary, OOD, AD and limited liability forms

A subsidiary is a Bulgarian company owned by the foreign parent, most commonly a limited liability company (OOD) or its single-member form (EOOD), or a joint-stock company (AD). Its defining features include:

• Separate legal personality. The subsidiary contracts, owns assets, sues and is sued in its own name.
• Limited liability. The parent’s exposure is generally confined to its capital contribution, subject to statutory exceptions.
• Share capital. The OOD carries a nominal statutory minimum capital, while the AD requires a higher statutory minimum, reflecting its role as a vehicle for larger operations and potential capital raising.
• Full trading capacity. A subsidiary can hire, contract, hold licences and operate as a resident Bulgarian company.

Quick primer: Bulgarian company types and where branch/subsidiary fit

Foreign company Bulgaria setup usually reduces to a short list of recognised vehicles under the Commercial Act. Knowing the Bulgarian company types helps you place the branch and subsidiary routes in context and avoid choosing a structure that will not carry your commercial plan.

• OOD (дружество с ограничена отговорност). The private limited liability company, the workhorse for most foreign subsidiaries, owned by one or more members with liability limited to contributions.
• EOOD. The single-member OOD, ideal where a foreign parent wishes to be sole owner.
• AD (акционерно дружество). The joint-stock company, used for larger operations, regulated activities or where transferable shares and capital raising matter.
• Branch (клон). A registered extension of the foreign company, no separate personality.
• Representative office. A non-trading presence for liaison and promotion, unable to carry on commercial activity.
• Permanent establishment (PE). A tax concept, not a registration form, it determines whether Bulgarian corporate tax applies to a foreign presence.

Minimum capital and basic formalities for OOD/AD

The OOD is designed to be accessible: it carries a low nominal statutory minimum capital set by the Commercial Act, making it straightforward to fund on formation. The AD requires a substantially higher statutory minimum, consistent with its use for larger or regulated ventures. In both cases, capital is stated in the constitutive documents and evidenced on incorporation. Following euro adoption from 1 January 2026, capital denomination and accounting conventions follow the official currency framework communicated by the Bulgarian National Bank and the relevant authorities; confirm the applicable denomination and current statutory minimums at the time of filing.

Representative office vs branch, practical differences

A representative office cannot trade, invoice or conclude commercial contracts; it is limited to marketing, market research and liaison activities and is registered with the Bulgarian Chamber of Commerce and Industry rather than the Commercial Register. A branch, by contrast, can carry on the parent’s business activity in Bulgaria and generate revenue locally. If your plan involves signing customer contracts or generating turnover, a representative office is insufficient, the realistic choice is between a branch and a subsidiary.

Step-by-step registration: branch vs subsidiary Bulgaria

Both routes are filed with the Commercial Register maintained by the Registry Agency, but the document sets and preparatory steps differ. Below are practical, sequenced checklists for each. Foreign documents typically require apostille or legalisation and certified Bulgarian translation, and specimen signatures must usually be notarised.

Bulgarian branch registration, documents, filings, timeline and fees

1. Corporate resolution. The foreign parent adopts a decision to open a Bulgarian branch and appoint a branch manager.
2. Parent company evidence. Certified extract from the parent’s home register and constitutive documents, apostilled or legalised and translated into Bulgarian.
3. Power of attorney. Authority for the branch manager and, where relevant, for the local representative handling the filing.
4. Specimen signature. Notarised specimen of the branch manager’s signature.
5. Registry filing. Submit the application and supporting documents to the Commercial Register at the Registry Agency, pay the official registration fee and obtain the branch’s unique identification code.
6. Tax and social security registration. Register with the National Revenue Agency where the branch creates a permanent establishment, and enrol for payroll and social security once local staff are hired.

Realistic timing for Bulgarian branch registration runs from roughly two to six weeks, driven mainly by how quickly apostilled and translated parent documents can be assembled.

Subsidiary incorporation, articles, capital, notary and registration

1. Choose the form. Decide between OOD/EOOD and AD based on ownership, capital and activity.
2. Constitutive documents. Prepare the articles of association (or memorandum for a single-member EOOD), appoint the manager(s) and set the registered seat.
3. Capital contribution. Deposit the share capital into a Bulgarian accumulation account and obtain confirmation of payment.
4. Notarisation. Notarise the manager’s specimen signature and consent to act, and any documents requiring notarial form.
5. Registry filing. File the incorporation application with the Commercial Register at the Registry Agency, pay the official fee and receive the company’s unique identification code.
6. Post-incorporation registrations. Register with the National Revenue Agency for tax, apply for VAT where thresholds or activity require it, and enrol for social security when hiring.

Subsidiary incorporation typically takes three to eight weeks, with the accumulation account and bank onboarding often driving the longer end of the range.

Timelines, fees and practical timings

Company registration timeline Bulgaria depends on document preparation abroad, notarisation, bank onboarding and the registry’s processing. The table below summarises the branch vs subsidiary Bulgaria comparison across the core dimensions foreign entrants ask about most.

Fastest-case timelines assume the parent’s documents are already apostilled and translated and that bank KYC clears without additional requests. In practice, three delays recur: bank onboarding and KYC on foreign shareholders; apostille or legalisation of home-country documents; and certified translation turnaround. Expedited registry handling can shorten the filing stage, but it cannot compensate for slow document preparation abroad, so start the apostille and translation workstream early. External counsel timelines usually mirror these stages: a few days to draft and collect documents, then the statutory registry processing window once everything is filed.

Liability: directors, parent company and permanent establishment risks

Liability is often the deciding factor in the branch vs subsidiary Bulgaria analysis. A branch does not insulate the parent, whereas a properly capitalised and governed subsidiary generally confines exposure to the Bulgarian company. But limited liability is not absolute, and directors carry personal duties in either structure.

Director duties and statutory liabilities

Under the Commercial Act, managers and board members owe duties to act in the interests of the company and within their mandate. Breaches can trigger civil liability to the company and, in defined circumstances, to creditors. Liability of directors Bulgaria commonly arises from failing to file mandatory registrations, allowing tax or social security defaults, keeping inadequate books, or continuing to trade when the company can no longer meet its obligations. Serious defaults, particularly around tax and payroll, can escalate into administrative penalties and, in egregious cases, criminal exposure. Directors should document decisions, maintain compliant records and act promptly where solvency is in doubt.

Parent company exposure

With a branch, the foreign parent is the legal actor: contracts bind the parent, and creditors of the branch can pursue the parent directly. With a subsidiary, the parent’s exposure is generally limited to its capital contribution, unless it has given guarantees, entered into direct contracts, or engaged in conduct that pierces the corporate separation. Parent groups frequently underestimate how guarantees, comfort letters and intra-group financing can re-import liability that the subsidiary structure was intended to contain. Draft these instruments deliberately.

Employment and social security liabilities for local staff

Once you hire in Bulgaria, both structures assume employer obligations: registering employment contracts with the National Revenue Agency, withholding and remitting income tax, and paying social security contributions. Payroll defaults are a recurrent trigger of manager liability, because unpaid public dues attract enhanced enforcement. Whether you operate a branch or a subsidiary, treat payroll compliance as a board-level control, not an administrative afterthought.

Tax considerations and euro adoption 2026 implications

Tax treatment is a core pillar of the branch vs subsidiary Bulgaria decision. A subsidiary is a Bulgarian tax resident and is taxed on its worldwide profits under domestic rules, subject to applicable double tax treaties. A branch is taxed in Bulgaria only to the extent it constitutes a permanent establishment, on profits attributable to that establishment. Confirm the current corporate income tax rate, VAT registration thresholds and withholding tax positions with the National Revenue Agency at the time of setup, as these are the operative figures for planning.

Transfer pricing rules apply to dealings between a subsidiary and its group, and PE attribution rules govern how much of a branch’s activity is taxed locally, both areas benefit from early advice.

VAT and payroll practicalities

VAT registration is driven by turnover thresholds and the nature of your activity; some businesses register voluntarily to recover input VAT from the outset. Both branches and subsidiaries operate payroll subject to income tax and social security obligations administered through the National Revenue Agency, deducting income tax and social security and filing periodic returns. Build a Bulgarian-language accounting function or engage a local provider before you begin invoicing, because compliance obligations start with the first transaction.

Banking, multi-currency and euro adoption practicalities

Corporate banking is where 2026 euro adoption bites most immediately. Following Bulgaria’s adoption of the euro on 1 January 2026, account denomination, statement currency and payment conventions have shifted from the lev to the euro under the official framework administered by the Bulgarian National Bank. For foreign groups this affects capital contributions, intra-group funding and profit repatriation. Practical steps include confirming account currency arrangements with your bank, reviewing intercompany loan and dividend documentation for currency references, and updating accounting systems for the transition. Because bank onboarding for foreign-owned entities already tests timelines, incorporate the euro-transition considerations into your banking plan rather than treating them as a later fix.

Compliance and ongoing obligations

Whichever route you choose, ongoing compliance is continuous, not one-off. Bulgarian entities file annual financial statements and tax returns, maintain statutory books and registers, and keep accounting records in accordance with Bulgarian law. Anti-money-laundering and beneficial ownership obligations apply, and data protection rules govern employee information. Missed filings feed directly back into the director liability analysis above.

Accounting and audit thresholds

Companies must keep books in Bulgarian and file annual accounts with the Commercial Register. Statutory audit applies once a company exceeds the applicable size thresholds under the Accountancy Act; confirm the current thresholds before assuming your entity is exempt, as they change and are tied to balance-sheet, turnover and headcount tests. Branches likewise maintain separate local accounting for their Bulgarian activity.

AML and beneficial owner register

Bulgarian entities are subject to beneficial ownership disclosure under the Measures Against Money Laundering Act and must maintain accurate records of their ultimate beneficial owners, filing this information with the Commercial Register as required. AML and KYC obligations also affect onboarding with banks and professional service providers. Keep beneficial ownership data current, changes in the group above the Bulgarian entity can trigger update filings.

Decision framework: when to choose a branch vs subsidiary

Use this matrix to align structure with commercial reality across scale, liability appetite, tax, financing, staffing and exit planning.

• Commercial scale. Light-touch or single-activity presence favours a branch; sustained trading favours a subsidiary.
• Liability appetite. If ring-fencing the parent matters, choose a subsidiary; a branch exposes the parent directly.
• Tax profile. A subsidiary is a clean resident taxpayer; a branch’s taxation turns on PE attribution.
• Financing. A subsidiary can raise capital and hold assets in its own name; a branch relies on the parent.
• Staffing. Large local teams typically sit better inside a subsidiary.
• Exit or transfer. A subsidiary’s shares can be sold; a branch cannot be transferred as an independent entity.

Scenario one, market test: a manufacturer wants to gauge Bulgarian demand with a small representative team and a handful of contracts. A branch offers a quicker, lower-cost footprint. Scenario two, full operations: a group plans a Bulgarian operating hub with dozens of staff, local contracting and third-party financing. A subsidiary provides limited liability, financing flexibility and a clean exit vehicle.

Practical checklists: documents and timelines

Prepare the following in the home jurisdiction before filing.

• Corporate resolutions authorising the branch or subsidiary and appointing the manager(s).
• Certified register extract and constitutive documents of the parent, apostilled or legalised.
• Certified Bulgarian translations of all foreign documents.
• Notarised specimen signatures and consent to act for managers.
• Powers of attorney for local representatives handling the filing.
• Capital deposit confirmation (subsidiary only), evidencing payment into the accumulation account.
• Registered seat details and any activity-specific licences or permits.

Costs: official fees and professional fees

Budget for several distinct cost lines: official Commercial Register fees; notary fees for signatures and any notarised documents; certified translation of foreign documents; bank account opening and maintenance fees; and professional retainers for legal and accounting support. Registry and notary charges are set by published schedules and are relatively modest, while translation and professional fees vary with document volume and complexity. Because official fees and thresholds change, confirm current figures against the Registry Agency and notary fee schedules before finalising your budget.

Next steps

The branch vs subsidiary Bulgaria decision rewards early, structured planning, particularly in 2026, when euro adoption reshapes banking and treasury mechanics alongside tighter compliance expectations. Map your commercial plan against the decision framework above, assemble your document checklist, and confirm current fees, tax rates and thresholds with the official sources before filing.
