EOOD Substance Requirements in Bulgaria: How to Prove Your Company Is Real

Why Substance Matters: The Two-Directional Risk

You registered a Bulgarian EOOD. You have a Bulgarian bank account, an accountant, and a tax number. But that does not mean your company has substance — and without substance, your company is a liability, not an asset.

Substance risk runs in two directions simultaneously:

• Bulgaria's National Revenue Agency (NRA): If your EOOD has no real activity in Bulgaria — no office, no employees, no local expenses — the NRA can reclassify it, deny deductions, or apply GAAR (General Anti-Avoidance Rule) provisions under Articles 15–16 of the Tax Procedure Code. More practically, a company with zero substance often triggers a registration refusal for VAT, which is the NRA's first and most common signal that something is wrong
• Your home country's tax authority: This is the bigger risk. If you are (or were recently) tax-resident in Germany, France, the Netherlands, or any country with CFC rules, your home country can look through your EOOD entirely. They can attribute its profits to you personally, tax them at your home country rate, and add penalties and interest on top. Your EOOD's Bulgarian registration means nothing if it has no genuine economic life in Bulgaria

What Constitutes "Substance" for a Bulgarian EOOD

Substance is not a checklist you can fake. It is the totality of evidence that your company has genuine economic activity in Bulgaria. Tax authorities — both Bulgarian and foreign — assess substance holistically. But six elements form the core:

1. Registered Office — A Real Address

Your EOOD must have a genuine business address in Bulgaria. This is not about legality — any address satisfies the Commercial Register. This is about credibility under scrutiny.

• What works: A dedicated office, a shared/coworking space with a desk you actually use, a serviced office where mail is received and meetings can happen
• What does not work: A virtual office address shared by 200 other companies, your accountant's address (unless you actually work from there), a residential address where you have never lived
• Why it matters: When a foreign tax authority sends an information request to the Bulgarian NRA, the NRA may visit the registered address. If no one is there, no sign of activity exists, and the building receptionist has never heard of your company — that information goes into the exchange file

2. Local Bank Account with Actual Transactions

A Bulgarian bank account that receives one large inbound transfer per year and sends one large outbound transfer is not evidence of substance. It is evidence of a pass-through entity.

• What works: Regular transactions — receiving client payments, paying rent, paying salaries or contractor fees, paying for software subscriptions, utilities, professional services. A pattern that looks like a real business operating
• What does not work: An account opened at registration, used once or twice, or an account where the only activity is receiving revenue from abroad and transferring it to the owner. Opening a Bulgarian bank account is necessary but not sufficient — the account must show life

3. Director with Decision-Making Authority in Bulgaria

The EOOD's управител (manager/director) must have genuine authority and must exercise it from Bulgaria. This is the single most important substance factor.

• If you are the director: You must be physically present in Bulgaria for a meaningful portion of the year and make business decisions from here. Contracts should be signed in Bulgaria. Emails to key clients should originate from Bulgarian IP addresses. Your travel records should show you spend substantial time in the country
• If you appoint a local director: That person must have genuine authority — not a nominee who rubber-stamps your decisions. They must understand the business, participate in real decision-making, and be able to answer questions if the NRA or a foreign authority inquires

4. Employees or Contractors (At Least Part-Time)

A company with zero employees — where the sole owner-director does everything from another country — is the textbook definition of a shell. Even a solo founder should have:

• A part-time local assistant who handles administrative tasks, office coordination, or customer support
• Local contractors who provide services to the company — developers, designers, marketing, whatever your business actually does
• At minimum, a local accountant engaged on a regular retainer (not just for the annual filing)

5. Board Meetings and Management Decisions Documented in Bulgaria

Even for a single-member EOOD, you should document key management decisions as written resolutions of the sole owner (решения на едноличния собственик на капитала). These should be:

• Dated with a Bulgarian location
• Covering real business decisions: annual business plan, major contracts, hiring, investment decisions, dividend distributions
• Held at least quarterly — not just once a year for the annual accounts
• Signed physically in Bulgaria (or, if remote, with a clear record showing the decision-maker was acting from Bulgaria)

6. Accounting and Compliance Handled Locally

Your company's books must be kept in Bulgaria by a Bulgarian-licensed accountant. This is both a legal requirement and a substance indicator:

• Monthly bookkeeping and VAT filings (if VAT-registered)
• Annual financial statements filed with the Commercial Register
• Annual corporate tax return (Form 1010, filed by June 30)
• Full compliance with Bulgarian filing deadlines

Minimum Substance Checklist for Solo Founders

You are a solo founder. You run a one-person consultancy, SaaS, or freelance operation through a Bulgarian EOOD. You cannot hire a team of five. What is the bare minimum to be safe?

The Place of Effective Management (POEM) Test

Where is your company actually managed? Not where it is registered — where its management decisions are substantively made and carried out. This is the POEM test, and it determines your company's true tax residence.

Article 4 of the OECD Model Tax Convention

When a company is registered in Bulgaria but potentially managed from another country, Article 4(3) of the OECD Model provides the tiebreaker: the company is tax-resident where its place of effective management is situated. The OECD Commentary identifies these factors:

• Where the board of directors meets: If your board (or sole owner) decisions are made in Germany, the company's POEM may be Germany
• Where the CEO/managing director operates day-to-day: If you sit in Amsterdam running the company, the POEM is Amsterdam
• Where key management and commercial decisions are made: Where contracts are negotiated, where client relationships are managed, where strategic direction is set
• Where the company's books and records are kept: A secondary factor, but relevant — if everything is in Bulgarian and stored with your Bulgarian accountant, that supports Bulgarian POEM

How Bulgaria Applies POEM

Under Article 3(2) of the Bulgarian Corporate Income Tax Act (ЗКПО), a foreign entity is considered to have its place of effective management in Bulgaria if its day-to-day operational management is conducted from Bulgaria. This is a mirror test — if Bulgaria would claim POEM over a foreign-registered company managed from Sofia, other countries can (and do) claim POEM over Bulgarian-registered companies managed from their territory.

How Other Countries Apply POEM

This is where it gets dangerous for EOOD owners who live abroad:

• Germany: The Abgabenordnung (§10–12 AO) defines Ort der Geschäftsleitung (place of management) as the place where the essential management decisions are actually made. German courts consistently look at the physical location of the director when decisions are taken. If you live in Munich and manage your Bulgarian EOOD from your Munich apartment, the EOOD's POEM is Germany — and it is subject to German corporate tax at ~30%
• France: French jurisprudence applies a similar test: where the company's organs of direction, administration, and control effectively function. The Conseil d'Etat has held that a foreign company managed from France is French tax-resident regardless of its place of incorporation
• Netherlands: Dutch law uses the "place of effective management" criterion under Article 4 of the Wet op de vennootschapsbelasting. The Hoge Raad has ruled that POEM is where the actual, rather than formal, management decisions are made

CFC Rules: When Your Home Country Taxes Your EOOD's Profits

Controlled Foreign Company (CFC) rules allow your home country to tax the undistributed profits of your foreign company as if they were your personal income. These rules exist specifically to prevent residents from parking income in low-tax companies abroad.

Bulgaria's CFC Implementation Under ATAD

Bulgaria transposed the EU Anti-Tax Avoidance Directive (ATAD) CFC rules into the Corporate Income Tax Act. Under the Bulgarian implementation:

• Ownership threshold: The Bulgarian parent (or individual) holds more than 50% of voting rights, capital, or profit entitlement in the foreign entity
• Tax rate test: The foreign entity pays an effective tax rate that is less than half the Bulgarian rate — meaning less than 5% effective tax
• Income composition test: More than 30% of the foreign entity's income is passive (dividends, interest, royalties, rental income, capital gains from shares)
• Effect when triggered: The undistributed passive income of the CFC is attributed to the Bulgarian parent and taxed at 10% Bulgarian corporate tax

In practice, Bulgaria's CFC rules primarily target subsidiaries in zero-tax jurisdictions (UAE, BVI, Cayman). If your EOOD's subsidiaries are in normal-tax EU countries, Bulgaria's CFC rules are unlikely to apply.

The Real CFC Danger: Your Home Country's Rules

The more pressing risk is that your home country applies its CFC rules to your Bulgarian EOOD. Bulgaria's 10% corporate tax rate, while the lowest in the EU, is above the ATAD minimum threshold (5%), but many countries have stricter national CFC rules that go beyond the ATAD minimum:

Home Country Risks: What Happens If They Challenge Your EOOD

Let us be specific about what happens when a home country tax authority decides your Bulgarian EOOD lacks substance.

Germany: The Außensteuergesetz (AStG) Challenge

Germany has the most developed anti-avoidance framework in the EU for foreign companies owned by German residents (or recent emigrants). The challenge typically unfolds like this:

1. Trigger: You file your German personal tax return (or deregister from Germany but the Finanzamt conducts a departure audit). They notice income from a Bulgarian EOOD
2. Information exchange: Germany requests information from Bulgaria under EU Directive 2011/16 (Directive on Administrative Cooperation). The Bulgarian NRA responds with what it knows about your EOOD
3. AStG §7 assessment: If the EOOD earns passive income and pays <25% effective tax, the Finanzamt attributes that income to you under Hinzurechnungsbesteuerung (addition taxation)
4. Alternatively — POEM challenge: If the Finanzamt determines you managed the EOOD from Germany, they classify it as German tax-resident entirely, subjecting all income to ~30% German corporate tax
5. Penalty: Back taxes + 6% annual interest (§233a AO) + potential Steuerhinterziehung (tax evasion) prosecution under §370 AO if the Finanzamt considers the omission deliberate

France: Article 209 B and Article 123 bis

France applies CFC rules differently depending on whether you hold the EOOD through a French company (Article 209 B CGI) or as an individual (Article 123 bis CGI):

• Article 209 B: If a French company holds ≥50% of your Bulgarian EOOD and the EOOD is subject to a "privileged tax regime" (<50% of France's rate — 10% vs 12.5% threshold), the EOOD's profits are attributed to the French company
• Article 123 bis: If you personally hold ≥10% of a company in a low-tax jurisdiction, its undistributed income can be attributed to you personally
• Defense: You must prove the EOOD has a genuine industrial or commercial activity in Bulgaria. This is a substance test — and France applies it strictly

Netherlands: Substance-Over-Form Doctrine

The Netherlands applies a pragmatic approach. While its statutory CFC threshold (9%) is below Bulgaria's 10%, the Dutch Belastingdienst can still challenge your EOOD under:

• Fraus legis (abuse of law): If the EOOD's sole purpose is tax avoidance with no genuine economic rationale
• Article 13ab Wet vpb: The CFC measure for passive assets and activities
• Beneficial ownership challenges: The Belastingdienst may argue that income flowing through the EOOD is beneficially owned by you in the Netherlands, especially if you maintain de facto management from there

Transfer Pricing for Owner-Company Transactions

When you — the sole owner — transact with your own EOOD, every transaction must be at arm's length. This means the price must be what two unrelated parties would agree on in comparable circumstances. Bulgaria follows the OECD Transfer Pricing Guidelines, and the NRA can adjust transactions that deviate from arm's length.

Red Flags That Attract Scrutiny

Tax authorities — both Bulgarian and foreign — use pattern recognition to identify shell companies. If your EOOD matches multiple red flags, expect attention. Here are the specific triggers:

• No local expenses: The EOOD's P&L shows zero rent, zero salaries, zero utilities, zero local professional fees. Revenue comes in, dividends or management fees go out. There is nothing in between
• All income from one country: 100% of revenue comes from Germany (or France, or the Netherlands). This signals that the EOOD may be a contract wrapper — not a genuine business operating from Bulgaria
• Director never visits Bulgaria: Passport stamps, airline records, and IP logs all show the director is always somewhere else. If the director is never in Bulgaria, the company's POEM is not Bulgaria
• No local bank activity: The Bulgarian bank account shows one large inbound transfer per quarter and one large outbound transfer. No salaries, no rent payments, no vendor payments, no operational cash flow
• Company address is a known virtual office: The NRA and foreign tax authorities maintain lists of addresses associated with hundreds of shell companies. If your address is on one of these lists, expect automatic scrutiny
• No local contracts or suppliers: The EOOD has no contracts with Bulgarian suppliers, no local service agreements, no evidence of purchasing anything in Bulgaria
• Management documents in the wrong language/timezone: Board resolutions drafted in German, signed at 9 AM CET but the director was in Thailand (where it was 3 PM), with no Bulgarian translation. These details matter in audits
• Company created immediately after deregistering from a high-tax country: You deregister from Germany in January, register a Bulgarian EOOD in February, and start invoicing your German clients through it in March. This is the most audited pattern in EU tax administration

How to Build Substance Affordably

Substance does not require luxury offices and full-time staff. It requires genuine, documented, consistent economic activity in Bulgaria. Here is how to build it without overspending:

Shared Office: EUR 100–300/month

Sofia has dozens of coworking spaces and shared office providers. A dedicated desk or small private office in a coworking space gives you:

• A real business address (not flagged as a virtual office)
• A place to receive mail and hold meetings
• Access to meeting rooms for quarterly board meetings
• A legitimate local expense on your P&L

Options outside Sofia (Plovdiv, Varna, Burgas) can be even cheaper while providing the same substance evidence.

Part-Time Local Assistant: EUR 200–400/month

Hire a part-time local contractor or employee (10–20 hours/month) to handle:

• Administrative tasks: mail processing, document filing, bank transactions
• Client communication support (if applicable)
• Coordination with your accountant and any local service providers
• Office presence — someone who is at the address during business hours

This creates a local employment/contractor relationship, local payroll or invoice payments, and a person who can confirm the company's activity if ever asked.

Quarterly Board Meetings: EUR 0 (Your Time)

Every quarter, prepare and sign a written resolution of the sole owner covering:

• Review of financial performance for the quarter
• Key business decisions made or planned
• Approval of significant contracts or expenditures
• Dividend distribution decisions (if applicable)
• Any changes to business strategy or operations

Date them with the Bulgarian location. Store them with your company documents. This creates a documentary trail of management decisions made in Bulgaria.

Local Accounting: EUR 100–300/month

Engage a Bulgarian-licensed accountant on a monthly retainer — not just for the annual filing. Monthly bookkeeping, VAT compliance (if registered), and regular financial reporting create both compliance and substance evidence. Your accountant is also your first line of defense if the NRA asks questions.

Total Annual Cost: EUR 4,800–12,000

For a solo founder, genuine substance costs EUR 400–1,000/month. Compare this to the tax savings: if your EOOD earns EUR 100,000 in active income, the difference between 10% Bulgarian tax and 30–45% in your former home country is EUR 20,000–35,000/year. Substance costs are a fraction of the benefit — and they are themselves tax-deductible expenses of the EOOD.
