10% Corporate Tax — The Reason Getting Setup Right Matters
Introduction
Bulgaria’s 10% corporate tax, rapid company registration and EU single market access make it one of the most attractive jurisdictions in Europe for foreign entrepreneurs. The EOOD registration process itself is straightforward — in theory, a company can be registered in three business days with complete documentation.
In practice, a significant proportion of foreign entrepreneurs encounter avoidable delays, bank refusals, tax complications and legal problems that trace back to errors made in the first steps of the process. These errors are consistent — the same mistakes recur across nationalities, business types and sectors. They arise not from complexity but from unfamiliarity: with Bulgarian law, with Bulgarian banking requirements, with Bulgarian tax obligations, and with the gap between what a Bulgarian company looks like on paper and what authorities, banks and counterparties need to see in practice.
This guide documents the fifteen most common and most costly mistakes, explains exactly what goes wrong in each case, and provides the specific steps to avoid them. The goal is not to discourage — Bulgaria remains an excellent destination for foreign business registration. The goal is to ensure that the advantages Bulgaria offers are actually realised, rather than offset by avoidable complications.
Why Foreign Entrepreneurs Make These Mistakes
Understanding the root causes helps explain why the same errors repeat across otherwise careful and experienced business people.
- Bulgarian law differs materially from the legal systems most foreign entrepreneurs know — German, UK, US, Israeli, Russian or CIS legal frameworks all have structural differences from Bulgarian company law, tax law and employment law that are not obvious without specialist knowledge;
- The language barrier is real: the Commercial Register, tax authority publications, banking requirements and most official communications are in Bulgarian. Relying on machine translation of legal documents is a significant risk;
- Online information about Bulgarian company registration — including much of what appears in English — is outdated, incomplete or written without knowledge of current practice;
- Foreign entrepreneurs often apply the logic of their home jurisdiction: ‘In Germany we do it this way’ or ‘In the UK this document is sufficient.’ Bulgarian requirements frequently differ in ways that are not intuitive;
- The DIY instinct: attempting to register a company, prepare documents, or open a bank account without local professional support to save money — typically resulting in costs that substantially exceed what professional support would have cost.
The 15 Mistakes — In Detail
#1 Choosing the Wrong Legal Structure
What goes wrong: The foreign entrepreneur registers a branch (клон) when they need a subsidiary, or registers a sole trader (ЕТ) when they need limited liability, or chooses an OOD when an EOOD would be simpler and cheaper. Each structure has different tax treatment, liability implications, and administrative requirements.
How to avoid it: Understand the four main options before registering. EOOD (single-owner limited company) suits most foreign entrepreneurs: limited liability, 10% corporate tax, simple governance. OOD is for multi-shareholder structures. Branch keeps the parent’s liability exposed and has specific accounting obligations. Sole trader carries unlimited personal liability and is rarely appropriate for foreign nationals.
| Structure | Liability | Min. Capital | Corporate Tax | Best For |
|---|---|---|---|---|
| EOOD | Limited to capital | BGN 2 | 10% | Most foreign entrepreneurs — single owner, flexible, simple |
| OOD | Limited to capital | BGN 2 | 10% | Joint ventures; 2+ shareholders; investor partnerships |
| Branch (Клон) | Unlimited (parent liable) | None | 10% on Bulgarian profit | Specific projects; testing the market; short-term presence |
| Rep Office (Представителство) | None — cannot trade | None | Not a taxpayer | Market research only; no commercial activity permitted |
| Sole Trader (ЕТ) | Unlimited personal | None | 15% on profit | Bulgarian residents only; very small operations; not for foreigners |
#2 Registering Without a Clear Business Activity Description
What goes wrong: The company is registered with vague activity descriptions (‘consulting’, ‘trade’, ‘services’) or with NACE codes that don’t match the actual business. Banks then ask what the company actually does, cannot assess the transaction profile, and either refuse the account or apply enhanced due diligence that delays opening by weeks.
How to avoid it: Before registering, prepare a clear 2–3 paragraph description of what the company will do, who its clients will be, where revenue will come from, and what transactions will flow through the account. This is not a business plan — it is a compliance document for banking purposes. Select NACE codes that accurately reflect the primary and secondary activities. Mismatched codes create problems not just at account opening but in annual statistical reporting and sector-specific licensing.
#3 Using an Incorrect or Inadequate Registered Office Address
What goes wrong: The company is registered at a virtual office address that the bank recognises as a mail-forwarding service with no genuine commercial presence, or at a residential address that does not match the stated business activity. Banks increasingly check registered addresses during account opening — a virtual office with no staff or activity is a red flag.
How to avoid it: The registered address must be genuine and must support the company’s claimed substance. For small remote-operated companies, a properly documented service office (not just a mailbox) with a service agreement demonstrating a real relationship is the minimum. For companies claiming significant Bulgarian operations, an actual office lease is required. Ensure the address matches the nature of the business described in your activity description.
#4 Ignoring Economic Substance Requirements
What goes wrong: The entrepreneur registers the company purely as a tax structure — no employees, no real office, no Bulgarian economic activity, all decisions made abroad. The company then cannot open a bank account, faces challenge on transfer pricing from the Bulgarian tax authority, and may be treated as a tax resident of the entrepreneur’s home country rather than Bulgaria by the home country’s tax authority.
How to avoid it: Economic substance means the company genuinely operates in Bulgaria: decisions are made or at least formalised by the Bulgarian director; there is a real office address; the company has at least one employee or demonstrable local engagement; contracts are signed through the Bulgarian entity. The level of substance required scales with the complexity and value of the transactions — a small consulting EOOD needs less than a holding company managing EUR 10 million of assets.
#5 Using a Nominee Director Without Understanding the Legal Consequences
What goes wrong: A nominee director is appointed for convenience — to have a Bulgarian name on the registration documents — without the nominee (or the entrepreneur) understanding that the director carries full legal responsibility for the company’s actions, has the power to bind the company contractually, and faces personal criminal liability if the company violates Bulgarian law. Nominee arrangements that are purely nominal (the nominee signs whatever is put in front of them without review) create serious legal risk.
How to avoid it: If a nominee director is used, the arrangement must be properly documented: a written agreement defining the scope of the director’s authority, clear limits on what they can sign without the shareholder’s prior written consent, and a proper power of attorney giving the shareholder control over key decisions. The nominee must understand what they are signing and must not be a mere rubber stamp. Bulgaria For Business VCC does not provide nominee directors as a pure convenience service — we insist on proper governance documentation.
#6 Incorrectly Prepared or Authenticated Corporate Documents
What goes wrong: The Articles of Association are prepared using a template that does not comply with current Bulgarian law. The shareholder resolution is not in the correct form. The power of attorney is notarised but not apostilled, or apostilled but not translated, or translated but not by a certified translator. Bulgarian notaries and the Commercial Register will reject documents that do not meet formal requirements — causing delays and requiring documents to be re-executed, often from the shareholder’s home country.
How to avoid it: Corporate documents for a Bulgarian company must: be prepared by a Bulgarian lawyer familiar with current Commercial Register requirements; any foreign-executed documents must be notarised in the country of execution, apostilled, and accompanied by a certified Bulgarian translation from a translator certified by the Bulgarian Ministry of Foreign Affairs. The apostille must be on the original notarised document, not on a copy. Never use a standard template downloaded from the internet.
| Document | Required Authentication | Common Error | Consequence |
|---|---|---|---|
| Articles of Association | Notarised in Bulgaria or apostilled if executed abroad | Prepared using outdated template; missing mandatory clauses | Commercial Register rejects application |
| Shareholder resolution | Notarised or in prescribed form | Unsigned; wrong format; missing details | Registration delayed; re-execution required |
| Power of Attorney | Notarised + apostilled + certified translation | Apostille missing; translation not certified | Cannot be used for registration; must be re-issued |
| Foreign company documents | Apostilled Certificate of Incorporation + certified translation | Only translated — apostille missing | Rejected by Commercial Register |
| Identity documents | Certified copy; certified translation if not in Latin/Cyrillic | Uncertified photocopy | Rejected; delays account opening |
#7 Underestimating Tax Obligations After Registration
What goes wrong: The company is registered, the bank account is opened, and then the entrepreneur discovers that Bulgaria has mandatory accounting, monthly payroll reporting for employees, quarterly VAT returns, annual financial statements filed with the Commercial Register, and an annual corporate income tax return — all with fixed deadlines and penalties for non-compliance. Many foreign entrepreneurs assume that a company with no turnover has no compliance obligations. It does.
How to avoid it: From the moment of registration, every Bulgarian company has compliance obligations regardless of whether it is actively trading. Engage a Bulgarian accountant before or immediately after registration — not when the first tax return is due. Understand the annual compliance calendar: monthly payroll reports if you have employees; VAT returns if registered; annual financial statements by 30 June; annual CIT return by 30 June; Commercial Register annual declaration by 30 June.
| Obligation | Frequency | Deadline | Penalty for Non-Compliance |
|---|---|---|---|
| Annual financial statements | Annual | 30 June of the following year | BGN 500–2,000 first offence; publication in State Gazette if unfiled |
| Corporate income tax return | Annual | 30 June of the following year | Interest on late payment; penalty for late filing |
| VAT return (if registered) | Monthly or quarterly | 14th of following month | BGN 500–5,000; interest on unpaid VAT |
| Payroll and social security reports | Monthly | 25th of following month | BGN 250–1,000 per violation |
| Commercial Register annual declaration | Annual | 31 March | Struck-off risk for persistent non-filing |
| Intrastat report (if applicable) | Monthly | 14th of following month | BGN 200–2,000 per violation |
#8 Missing or Delaying VAT Registration
What goes wrong: The company reaches BGN 100,000 turnover without having registered for VAT, triggering a mandatory registration that should have occurred earlier — with liability for VAT that should have been charged on prior invoices. Or conversely, a company providing services to EU VAT-registered clients operates without VAT registration and issues invoices that its EU clients cannot use for input VAT recovery — creating commercial problems.
How to avoid it: Understand the two VAT registration triggers. Mandatory: when taxable turnover in any 12-month period exceeds BGN 100,000 (approximately EUR 51,000) — application must be submitted before the end of the month in which the threshold is crossed. Voluntary: available at any time, and advisable for companies working with VAT-registered EU clients (to enable reverse charge on B2B services) or making significant input VAT purchases. Also note: EU VAT registration for distance selling and digital services has its own rules under the OSS scheme.
#9 Failing to Open a Corporate Bank Account — or Getting It Wrong
What goes wrong: The bank account application is rejected because the company’s documentation is incomplete, the source of funds is not adequately explained, the business activity description is too vague, the UBO declaration is missing or incorrectly completed, or the beneficial owner’s background triggers enhanced due diligence that the applicant was not prepared for. Account opening then takes 4–6 weeks instead of 3–5 days, or is refused entirely.
How to avoid it: Prepare a complete, well-organised documentation package before approaching any bank. Bulgarian banks operating under post-FATF grey list AML requirements are thorough — they will ask for source of funds, source of wealth, business model description, expected transaction profile, and counterparty information. Having all of this documented in advance, in English and Bulgarian where required, is the most effective way to ensure smooth account opening. Choose the bank based on your specific profile — UniCredit Bulbank and UBB are most experienced with foreign-owned companies.
| Bank Requirement | What Is Needed | Common Failure |
|---|---|---|
| Commercial Register extract | Dated within 30 days; shows company structure and directors | Outdated extract; not translated |
| UBO declaration | Completed form per EU 4th AML Directive; all beneficial owners identified | Incomplete; missing intermediate ownership layers |
| Source of funds documentation | Bank statements, income documentation, company financial statements showing origin of funds | Vague explanation; no supporting documents |
| Business activity description | Clear description of business model, clients, revenue sources, expected transaction flows | Too vague (‘consulting’); inconsistent with NACE codes |
| Director’s identity verification | Valid passport; in some cases, in-person verification or video KYC | Expired passport; refusal of in-person visit |
| Registered office confirmation | Lease agreement or service office agreement; utility bill or official address confirmation | Virtual office with no supporting documentation |
#10 Ignoring Mandatory Accounting Requirements
What goes wrong: The entrepreneur assumes that because the company has little activity, no accounting is needed. Bulgarian law requires all registered companies to maintain accounting records from the date of registration — regardless of activity level. A dormant company still has filing obligations. Missed filings result in penalties, and persistent non-filing can result in the company being struck off the Commercial Register.
How to avoid it: Engage a Bulgarian licensed accountant (дипломиран счетоводител) from the moment of registration. Annual costs for a small EOOD with simple operations are BGN 3,000–6,000 — negligible relative to the penalties and complications of non-compliance. The accountant handles monthly reports, annual financial statements, tax returns, and ensures the company remains in good standing with the NRA and the Commercial Register.
#11 Choosing Wrong or Insufficient NACE Activity Codes
What goes wrong: The company is registered with a single NACE code that does not cover all its intended activities, or with codes that are incorrect for its business. When the company later invoices for services not covered by its registered codes, questions arise during tax inspections. More seriously, some activities require a specific licence or permit — and operating without one is a regulatory violation, not merely an administrative oversight.
How to avoid it: Register with all relevant NACE codes at the outset — there is no limit on the number of codes and no additional cost for multiple codes. Identify whether any intended activities require a licence, permit or professional registration (financial services, healthcare, legal services, construction, tourism, food production, transport, and many others require specific authorisation). Adding new codes after registration is possible but involves an amendment procedure. Consult a Bulgarian lawyer about licensing requirements before starting any regulated activity.
#12 Failing to Protect Intellectual Property in Bulgaria
What goes wrong: The company begins operating in Bulgaria under a brand name or logo without registering it as a Bulgarian or EU trademark. A competitor or trademark troll registers the same or similar mark, creating legal complications and potentially forcing the company to rebrand in the Bulgarian market. Alternatively, the company’s software or creative work is used without a licence agreement, with no enforceable IP protection in place.
How to avoid it: Register your trademark with the Bulgarian Patent Office (for Bulgarian protection) or as an EU trademark via the EUIPO (for protection across all 27 EU member states — typically the more efficient choice for companies operating across the EU). EU trademark registration covers Bulgaria automatically. Domain name registration (.bg for Bulgarian presence) should be done simultaneously. Ensure all software development agreements, creative work commissions and employee contracts include clear IP ownership and assignment provisions.
#13 Ignoring Bulgarian Employment Law When Hiring
What goes wrong: An employment contract is signed but not registered with the NRA within the required 3-day period. Or the employment contract omits mandatory provisions (job description, working hours, notice period, probation period). Or social security contributions are calculated incorrectly. Or a foreign national is hired without first confirming their work authorisation status. Each of these is an administrative violation with associated penalties.
How to avoid it: Every employment contract in Bulgaria must: be in writing; contain all mandatory provisions specified in the Labour Code; be registered with the NRA within 3 days of signing (before the employee starts work); and be accompanied by correct social security registration. Foreign nationals require work authorisation before starting employment (EU citizens are exempt). Minimum wage requirements (BGN 1,077/month gross in 2025) apply to all employees. Consult a Bulgarian employment lawyer or accountant before signing the first employment contract.
#14 Buying Commercial Property Without Adequate Legal Due Diligence
What goes wrong: A commercial or industrial property is purchased without verifying the land use designation, building permit status, Act 16 certificate, existence of mortgages or easements, or outstanding municipal tax liabilities. The buyer discovers post-purchase that the building lacks Act 16 (cannot be legally used), or that an unregistered mortgage gives a bank priority over the buyer, or that the land use designation does not permit the intended activity.
How to avoid it: Never purchase commercial property in Bulgaria without commissioning independent legal due diligence from a lawyer with no connection to the seller or agent. The due diligence must cover: title and ownership chain; Property Register for all mortgages and encumbrances; building permit and Act 16 verification; land use (cadastre) designation; urban planning (zoning) plan parameters; environmental status; and municipal tax position. See our separate Property Valuation and Developer Due Diligence guides for the complete checklists.
#15 Trying to Save Money by Avoiding Professional Advice
What goes wrong: The entrepreneur registers the company using a template, opens the bank account without preparation, starts invoicing without VAT registration, hires employees without proper contracts, and then discovers — typically during a tax inspection, a bank account closure, or a commercial dispute — that multiple compliance failures have accumulated. The cost to fix the problems is a multiple of what proper professional support would have cost.
How to avoid it: The cost of proper legal and accounting support for a Bulgarian company registration is BGN 1,500–4,000 for the initial setup and BGN 3,000–8,000 per year for ongoing compliance — for a company with 10% corporate tax on whatever profit it generates. The cost of fixing avoidable mistakes — tax penalties, accounting backdating, legal disputes, bank account remediation — regularly reaches BGN 10,000–50,000 or more. This is not a close calculation.
