A foreign association, foundation, charity, or other non-profit legal person can establish a registered branch in Bulgaria without incorporating a second organisation. The branch gives the parent a Bulgarian address, representative, EIK identifier, staff platform, public Registry record, and a basis on which to seek a Bulgarian operating account. It does not put a separate legal person between the parent and the Bulgarian operation.

That distinction should drive the project. A branch is often efficient for a time-limited programme or a parent-controlled regional office. A Bulgarian association or foundation is usually better where local governance, separate assets, or liability separation matters.

This guide provides general information as at 1 August 2026. It is not legal, tax, accounting, employment, immigration, sanctions, banking, grant, or anti-money-laundering advice for a particular organisation or programme.

Foreign Non-Profit Branch at a Glance

What the Branch Is—and Is Not

Article 52(2) of the current Non-Profit Legal Entities Act (NPLEA) permits a foreign non-profit legal person to establish a Bulgarian branch when its purposes do not conflict with Bulgarian law or public order. The parent's existence, legal nature, organs, and capacity are governed by its home law. Bulgaria's Private International Law Code then applies Bulgarian law to the registered branch.

Registration does not create a Bulgarian association or foundation. Contracts should identify the foreign parent acting through its Bulgarian branch, and the parent remains exposed to the branch's liabilities. The branch representative acts within the registered and granted authority. An EIK makes the operating unit identifiable; it does not create separate ownership or capital.

This is different from a branch opened by an existing Bulgarian non-profit. For that route, see our Bulgarian non-profit branch guide.

EU and Non-EU Parents Follow the Same A18 Route

There is no general EU “NGO passport” that replaces Bulgarian branch registration. Article 54 TFEU expressly excludes non-profit-making legal persons from its definition of companies or firms for that establishment chapter. Other EU rights may still matter to a particular activity, but an EU-based charity files A18 just as a third-country charity does.

The practical difference is usually documentary. A treaty may waive legalisation between Bulgaria and the issuing state. If not, a public document from a Hague Apostille Convention state normally needs an apostille; a document from another state normally follows the applicable diplomatic or consular legalisation chain. The Bulgarian Foreign Ministry's guidance explains the three country-dependent regimes.

Do not assume that every EU document is apostille-free. Regulation (EU) 2016/1191 simplifies specified public documents concerning citizens, not a foreign non-profit's registry certificate, constitution, or board resolution as a general category. Confirm the rule for each issuing country and each document.

Decide the Bulgarian Scope and Benefit Status

The parent must decide which of its purposes the branch will pursue in Bulgaria. The NPLEA requires registration of both the parent's purposes and the subset to be carried out through the branch. The Bulgarian programme must remain within those purposes and comply with any sector-specific permit rules.

A foreign non-profit may conduct public-benefit activity through its Bulgarian branch under Article 38(2). Public-benefit status is not merely a translation of the parent's foreign charity label. It must be requested in the Bulgarian file, the purposes must fit Article 38, and the structure and operation must comply with Chapter Three's governance, conflict, spending, reporting, and publicity rules. Once public-benefit status is entered, the NPLEA treats the designation as irrevocable. If it is not selected, the branch operates in private benefit while remaining non-profit.

The A18 Registration Package

The Registry Agency's A18 service page is the correct workflow for initial registration and later changes. The filing records the foreign parent's name, national-register data, governing law, seat, representatives, and representation method. It also records the Bulgarian branch's distinctive Cyrillic name, seat and management address, representative, scope of authority, purposes, and any public-benefit designation.

Under the current Registry Regulation No. 1, the core attachments are:

• an official document proving the foreign non-profit's existence, its registered representatives, and representation method, where a home register exists
• the competent parent's resolution to open the Bulgarian branch, identifying the seat, address, purposes, benefit status, representative, and authority
• the parent's current constitution, statute, or equivalent governing document, including all amendments
• a second public copy of that governing document with personal data removed unless disclosure is legally required
• a power of attorney for the branch representative, bearing the notarised signature of the foreign parent's representative
• the branch representative's signature specimen
• the applicant's statutory truth declaration, filing authority, fee evidence, and any additional document required by the facts

The foreign resolution must come from the body competent under the governing document and home law. The existence certificate should be sufficiently current to prove the filing-day position; Bulgarian legislation does not create a universal “three-month validity” rule for every foreign registry extract.

Apostille, Legalisation, Translation, and Public Copies

Map the formalities before anyone signs. A home-registry certificate is a public document. A constitution or board resolution may be private, while a notarial authentication attached to it is public. That difference can change what must be apostilled or legalised. A legal-assistance treaty may remove authentication requirements altogether.

Every foreign-language attachment needs a Bulgarian translation suitable for the Registry. Coordinate the translated names, addresses, titles, and authority wording across the certificate, resolution, power, and A18 fields. A perfect apostille does not cure inconsistent transliteration or a decision taken by the wrong organ.

The Registry file is public. Submit the complete evidentiary version where required, but also attach the expressly required redacted public copy of the governing document. Remove passport numbers, private addresses, signatures, and other unnecessary personal data rather than publishing them by default.

Filing, Fees, and Timing

An eligible statutory applicant or authorised Bulgarian lawyer may file on paper or electronically. Online filing requires the appropriate portal access and qualified electronic signature; the discount is not limited to lawyer-filed applications. The 2026 Registry Agency fee tariff sets the converted initial fee at EUR 12.78 electronically or EUR 25.56 on paper. Apostille, consular, notary, translation, courier, and professional costs are separate.

The Registry Act's general rule is examination immediately after three working days from receipt. That is not an end-to-end promise. Obtaining a competent parent resolution, current foreign evidence, authentication, and a consistent Bulgarian translation often takes several weeks. Monitor the application page: if the registration officer publishes instructions, the correction window is short and a missed email is no defence.

After Registration: EIK, Banking, Ownership, and Staff

The branch receives its EIK automatically and is not separately entered as a new subject in BULSTAT. Use the exact registered parent-through-branch identity on contracts, invoices, employment records, and bank forms.

Beneficial ownership still requires a substantive analysis even though there are no shares in the branch. Identify the natural persons who ultimately control the foreign organisation under Bulgaria's anti-money-laundering rules; if no person can be identified after reasonable steps, assess the senior-managing- official fallback. A branch representative is not automatically the beneficial owner merely because their name is on A18. Where the data are not already available on the statutory basis, use the Registry Agency's B7 process and retain the supporting control documents.

Registration also does not oblige a bank to open an account. Expect KYC on the parent, branch representative, controllers, programme, donors, source of funds, and countries involved. Our business bank-account guide covers that separate onboarding exercise.

If the branch hires, the foreign parent acting through the branch becomes the employer for Bulgarian labour, payroll, social-security, and immigration purposes. Since June 2025, employment data are recorded in the NRA's Employment Register. Non-EU staff may need residence and work authorisation before starting.

Tax, VAT, Accounting, and Donations

“Non-profit” does not mean “outside the tax system.” A branch may create a Bulgarian permanent establishment for the foreign parent. Bulgaria's corporate-tax guidance taxes a foreign legal person's profit attributable to a Bulgarian permanent establishment, subject to the actual activity and any applicable tax treaty. Payments labelled grants, donations, sponsorship, membership fees, or services must be classified from their terms, restrictions, and consideration.

VAT is equally fact-sensitive. From 1 January 2026, the general domestic annual turnover threshold for a person established in Bulgaria is EUR 51,130, but special registration grounds can arise earlier, including cross-border services or acquisitions. The NRA's current VAT page should be applied to whether the foreign parent has a Bulgarian fixed establishment and to each supply. A18 also offers an optional VAT-registration request under Article 100(5); selecting it without a tax analysis is unwise.

Keep Bulgarian books and branch-level supporting records from day one. The applicable annual financial statements and reports now pass through Bulgaria's integrated annual-reporting channel and are reflected on the relevant Registry record. A public-benefit branch must also prepare the NPLEA annual activity report and publish it with its financial statements by 30 September of the following year. Donor reporting does not replace statutory accounting.

Changes, Parent Events, and Branch Closure

Registerable changes must be filed through A18 within the NPLEA's one-month period. This includes changes to the parent data, Bulgarian address, representative or authority, purposes, and public-benefit circumstances. A new representative requires a fresh notarised authority and signature specimen.

The Bulgarian record must also reflect the parent's liquidation, continuation, or insolvency. Closing the branch requires the parent's competent decision (or proof that the parent was deleted), settlement of contracts, staff, tax, bank, and reporting matters, and the A18 deletion filing. The current Regulation lists the National Social Security Institute certificate under Article 5(10) of the Social Security Code in the closure package; plan that step even if the branch has never hired and confirm the applicable NSSI procedure. A branch is not put through a separate Bulgarian-company liquidation merely because it has its own EIK.

Branch or a Bulgarian Association/Foundation?

Compare the forms in our association and foundation guide before the parent commits to a branch. The cheaper filing is not necessarily the better legal architecture.

Lion Consult can review the parent's home-law authority, structure the Bulgarian resolution and representative powers, coordinate the foreign-document formalities, prepare A18 and related filings, and map the post-registration compliance plan. Contact Lion Consult before documents are signed abroad, when corrections are usually easiest.

Frequently Asked Questions

Is a foreign non-profit branch a separate Bulgarian legal person?

No. It is the foreign parent operating through a registered Bulgarian unit; the parent remains the holder of branch rights and liabilities.

Which documents are needed for A18?

Home-register existence and representation evidence, parent resolution, current governing document plus redacted public copy, notarised representative authority, signature specimen, declarations and authority, translations, and applicable authentication.

Does an EU NGO always avoid an apostille?

No. EU Regulation 2016/1191 does not generally cover NGO registry and governance documents. Treaty waiver, Hague apostille, or consular legalisation must be checked by country and document.

What are the 2026 fees and Registry timing?

EUR 12.78 online or EUR 25.56 on paper. The general Registry stage is examined after three working days; foreign evidence, legalisation, translation, and instructions extend the full project.

Can the branch operate in public benefit?

Yes, if expressly requested and the Bulgarian Chapter Three conditions are met. The entered public-benefit designation is treated as irrevocable.

Does it receive an EIK and need BULSTAT?

The Registry generates an EIK automatically. A newly registered branch is not separately created in BULSTAT; banking remains a separate KYC decision.

Is a non-profit branch exempt from tax and VAT?

No blanket exemption. Tax follows the activities, permanent-establishment, and treaty facts; VAT can arise under the EUR 51,130 2026 domestic threshold or special cross-border grounds.
