Practical Experience with Foreign Entrepreneurs
We assist international founders, freelancers and consultants who need to understand whether an ET, self-employed setup or EOOD is the right structure for operating in Bulgaria.
A sole proprietorship in Bulgaria, legally the ET or едноличен търговец, is usually the cheapest and simplest way for one person to start trading under a registered business identity, but it comes with a nasty catch that people gloss over far too easily: there is no liability shield between you and the business. If the activity goes wrong, creditors do not stop politely at the business cash drawer. They keep walking toward your personal property.
That single point changes the whole conversation.
A lot of people searching “sole proprietorship in Bulgaria” are not really asking about legal theory. They’re trying to figure out whether they should register an ET, stay a freelancer, act as an independent contractor, or go straight into a company formation route with an EOOD. Fair question. In practice, the ET works best for low-risk, one-person activity with modest turnover, clean documentation, and no fantasy about separating business liabilities from private life. If you expect contracts with real exposure, employees, debt, investor money, or scale, this structure starts looking thin very quickly.
Bulgaria does make the ET look tempting at first glance. The registration process is relatively straightforward, there is no minimum capital requirement, the administrative entry cost is lower than an LLC, and the country still has that attractive tax environment people talk about for good reason. Yet the headline numbers can seduce founders into choosing the wrong vehicle. Bulgaria’s famous 10% corporate tax applies to companies, not to ET profit in the same way. A sole trader is taxed under personal income rules, and the social security side matters more than many first-timers expect.
The other confusion sits around freelancing. Plenty of people say “I’m a freelancer in Bulgaria” when they may mean one of several different things: unregistered casual activity, a self-employed professional registration, an ET, or a one-person EOOD invoicing clients. Those are not interchangeable. Taxation, accounting, liability, and compliance shift depending on which lane you’re actually in. The paperwork may look survivable. The legal consequences are where the grown-up decisions live.
And for foreigners, especially non-EU nationals, there is another layer. You cannot treat Bulgarian registration like a floating digital abstraction detached from immigration status, residence rights, local address requirements, and National Revenue Agency compliance. The remote process can exist in parts. Your actual ability to operate lawfully depends on the whole picture lining up, not just one form being stamped.

Before You Register as a Sole Proprietor in Bulgaria
A sole proprietorship in Bulgaria may look simple, but the correct choice depends on liability, taxation, residence status, accounting obligations and your long-term business plan.
LAW
Liability Is the Main Risk
An ET is not a separate limited liability company. If business obligations become serious, the owner may remain personally exposed. This is the key point many first-time founders miss.
TAX
Tax and Social Insurance Should Be Checked First
Bulgaria is attractive for business, but the tax treatment of a sole proprietor is not the same as an EOOD. Income tax, VAT registration and social insurance should be reviewed before filing.
What is an ET in Bulgaria?
Legal form
An ET is not a separate legal person in the way an EOOD is. That matters more than the label. Under the Bulgarian Commerce Act, the sole trader is a natural person registered in the Commercial Register to carry out commercial activity. Same human being. Same legal skin. The business name changes, the registration status changes, the tax and accounting consequences change, but the owner and the trader are not split into two independent entities.
That is why liability is unlimited. It is also why so many foreign entrepreneurs who are used to LLC logic misread the ET structure. They assume “registered business” means ring-fenced risk. It does not.
The legal backbone sits in the Commerce Act, which you can read in translation through the Commerce Act text and in official legislative form through the Ministry of Finance repository. If you’re comparing structures seriously, read the statute itself, not just blog summaries written by people trying to sell optimism.
The ET is part of Bulgarian commercial law, registered through the Registry Agency, listed in the Commercial Register, and treated as a merchant carrying out business activity. The registration gives you a formal trading identity. It does not create a wall around your assets. That wall is what an LLC is for.
Who uses it
In the real world, ETs tend to suit tradespeople, small retail operators, local service businesses, artisans, some low-risk consultants, and individuals who want a basic trading format without the additional corporate layer. Think small repair work, local commerce, craft production, modest service activity, maybe a solo operator billing a stable client base with limited contractual exposure.
It can also fit certain self-employed people who have moved beyond casual freelance work and need a registered commercial form for invoices, tax reporting, and longer-term operations in Bulgaria. Not glamorous. Useful.
Where it gets messy is with modern online work. A software developer, marketing consultant, designer, or cross-border independent contractor may technically operate as an ET, but that does not mean it is the best structure. If contracts include indemnities, data obligations, service-level commitments, or payment disputes across borders, using a structure with unlimited personal liability starts to feel less “simple” and more like cheap shoes in bad weather.
Core limits
The ET has three limits that matter far more than the sales pitch.
- There is no separation between business liability and personal property.
- Tax treatment does not mirror the 10% corporate income tax regime that makes Bulgarian companies so attractive.
- Banks, clients, and counterparties may still ask for extensive documentation, especially where foreign ownership, cross-border revenue, or regulated sectors appear.
There are also practical limits. Bringing in partners is not natural in this format. Raising investment is awkward. Restructuring later is possible, but it creates admin, tax, and contract migration work. So if you already know you are building something broader than a one-person operation, starting with an ET can be false economy.
Who can register one?
Bulgarian citizens
Bulgarian citizens have the cleanest path. A Bulgarian natural person with legal capacity can register as an ET if there is no statutory restriction blocking them, and the process runs through the Commercial Register maintained by the Registry Agency. Naming rules apply, declarations apply, and the activity must be lawful, but the underlying eligibility is straightforward.
The state’s own procedural view is laid out in the Unified Point of Single Contact guidance for commercial registration. It is worth reading because it deals with the practical edges people miss, including naming conventions and who can qualify.
One thing people skip over is that not every activity should be carried out through an ET even if registration is available. Professional licensing, sector regulation, health requirements, municipal permits, or special rules can sit on top of the basic registration process. So “can register” and “can lawfully operate this activity” are cousins, not twins.
EU nationals
EU nationals generally have a workable route as well, especially if they have the right residence status and local administrative setup in Bulgaria. The country sits inside the EU market, and that helps, but it does not erase Bulgarian registration formalities. You still need the correct identity documents, a local address trail, and proper filings.
The mistake some EU founders make is assuming free movement automatically turns into frictionless business administration. It does not. Commercial registration, tax registration, social insurance, and sometimes banking all want orderly paperwork. Bulgaria rewards people who bring a folder, not a vibe.
If you are an EU citizen planning a real presence in Bulgaria, an ET can be feasible for narrow, solo activity. If you are expanding a foreign company, hiring, or trying to build an investment-friendly footprint, a company formation route is often more sensible.
Non-EU residents
This is where wishful thinking usually crashes into a desk.
For non-EU nationals, the issue is not just “Can I file the forms?” The issue is residence rights, immigration status, and whether your legal presence in Bulgaria supports independent economic activity. A non-EU person without the right residence basis should not assume they can simply register and start operating. In practice, the residence prerequisite is often the real gatekeeper.
The European Commission immigration guidance for self-employed workers in Bulgaria is useful because it frames the immigration side honestly. The business registration does not float above immigration law. It sits inside it.
My blunt take matches what experienced advisors keep seeing: if you are non-EU and planning to live and work in Bulgaria long-term, sort the residence path first, then map the ET. Trying to reverse that order often leads to delay, confusion, or dead-end admin. The system likes alignment between your civil presence and your business activity. If those two are fighting each other, you’ll feel it early.
How does it compare with freelance work?
The wording here is slippery because “freelance” is commercial slang, not one precise Bulgarian legal form. Someone may call themselves a freelancer while operating as an ET, as a self-employed professional, as an unregistered earner, or through an EOOD. Same laptop. Very different legal consequences.
ET vs contractor
An independent contractor is a functional description. It tells you how you work, not necessarily what legal vehicle you use. You contract with clients, you are not their employee, and you invoice for services. Fine. That still leaves open the legal wrapper.
In Bulgaria, an independent contractor may operate through an ET. They may also operate under another self-employed basis, especially if they fall under a free profession model. The difference matters for registration, deductions, social contributions, bookkeeping, and how the tax declaration is prepared.
A simple way to think about it is this:
| Issue | ET | Freelance / self-employed professional |
|---|---|---|
| Legal basis | Commercial registration as merchant | Usually non-company self-employed basis tied to profession/activity |
| Liability | Unlimited personal liability | Also often personally exposed, depending on setup |
| Accounting | Can be more formal commercial accounting | Often simpler, but depends on activity and tax treatment |
| Commercial identity | Registered trade name in Commercial Register | May operate under personal identity/professional basis |
| Best use | Small trading activity, local commerce, solo operations | Independent services, professions, low-overhead client work |
This is why casual online advice goes sideways. People compare “ET” to “freelancing” as if one is a legal form and the other is a rival legal form. Not quite. Freelance is often the work style. ET is one possible structure.
ET vs EOOD
Now this comparison is cleaner, and honestly more important.
An EOOD is a single-member limited liability company. Separate legal entity. Separate accounting logic. Separate tax treatment. Better liability containment if operated properly. Usually the more serious choice for international entrepreneurs who care about asset protection, scalable incorporation, clearer contracts, and long-term EU market positioning.
The ET, by contrast, is cheaper and lighter at the start, but the owner absorbs business risk personally. That trade-off is not subtle. It is the whole game.
A lot of consultants in Bulgaria push founders toward EOODs, and frankly they often have a point. Not because the ET is invalid, but because founders love low setup cost and hate thinking about litigation, tax optimization limits, client disputes, or banking due diligence until it is too late. Bulgaria’s 10% corporate tax makes the EOOD even more attractive from a structuring perspective, especially when compared to the ET’s personal taxation framework.
If you want the fuller route around company formation in Bulgaria, that is usually where foreign founders eventually land anyway, because clients, banks, and partners tend to understand the LLC format more intuitively.

Best fit cases
The ET makes sense when the facts are plain and the risk is low. Usually something like this:
- You are one person running a modest activity with limited contractual exposure.
- You want a formal registration and invoicing path without setting up an LLC.
- You understand that your personal assets remain exposed and you are still comfortable with that.
For a Sofia-based freelance software consultant with stable recurring clients and low litigation risk, the ET can work. For an e-commerce seller taking product liability risk, or a consultancy signing heavy indemnity clauses, less charming. For a founder planning staff, subcontractor chains, foreign investors, or acquisition plans, wrong vehicle more often than not.
Register the business
Choose a name
The ET name is not just branding fluff. Bulgarian law requires the business name to include the name of the natural person, and it must not mislead or conflict improperly with existing registered names. This is one of those small formalities that can waste time if handled casually.
You can check naming and filing paths through the Registry Agency portal and use the public register environment explained through the European e-Justice overview of Bulgarian business registers. If the name is malformed or unavailable, the application can stall. It is not dramatic. Just annoying.
Founders sometimes want a sleek international trade label detached from their personal identity. The ET is not ideal for that instinct. The structure is built around the individual. If you want cleaner brand separation, the LLC route is usually better.
Prepare documents
The paperwork is manageable, but only if it is complete. Incomplete ET filings are one of the more boring ways to lose time.
Common documents usually include:
- the registration application, typically Form A1 for sole traders
- identity documents and specimen signature requirements where relevant
- declarations required under Bulgarian law
- proof for specific regulated activity, if the sector demands it
The official filing environment for the mandatory form sits through the Registry Agency form access. The Ministry of Economy SME handbook on legal form and registration documents also gives a more grounded procedural view than many glossy summaries online.
If you are a foreigner, add another layer: translation, legalization, apostille issues where needed, and consistency of names across passports, residence documents, and declarations. Tiny mismatch, real delay. Bulgaria can be forgiving on some things. Spelling discrepancies are rarely among them.
File the application
The application is filed with the Commercial Register at the Registry Agency. Electronic filing is possible in many cases, and local representation can help where language or technical access becomes a problem. The ET becomes active after successful registration, not when you merely decide you are “basically in business.”
Once registered, public data becomes visible through the register system. That transparency is useful for clients and authorities alike. It is also why sloppy filing choices follow you around.
The official state logic is fairly plain: register correctly, then handle the tax and insurance side quickly. The Ministry of Economy guide for self-employed startup steps is a decent reminder that registration is the beginning of compliance, not the end of it.
Meet tax and insurance rules
This part is where people who came for “simple” get their rude education.
Income tax
One of the most repeated misunderstandings about a sole proprietorship in Bulgaria is that people hear “Bulgaria” and “10% tax” and assume the ET automatically benefits from the same favorable setup as an LLC. No. That famous 10% corporate tax belongs to corporate entities. The ET is generally taxed through personal income rules, and sources commonly cite a 15% rate for ET taxable income under the personal framework. If you are structuring for tax optimization, that distinction is not cosmetic.
You need an accountant who understands Bulgarian tax law, not a motivational speaker.
The actual tax burden also depends on eligible expenses, activity type, and how your tax base is determined. Some self-employed persons talk about rough expense recognition rules and simplified assumptions, especially in service work, but you should be careful not to mash together ET rules with free profession treatment. Bulgaria has more than one path for solo economic activity, and the tax declaration changes with the path.
The practical point is simpler than the theory. Keep records. Keep invoices. Keep contracts. Keep expense support. If you do not document the business properly, your effective taxation gets worse. That pattern is almost universal.
VAT threshold
VAT registration becomes mandatory once taxable turnover crosses the statutory threshold, commonly referenced as 50000 EUR in a 12-month period. This is one of those thresholds people promise themselves they will “deal with later,” right before later turns into penalties, messy retroactive analysis, and a panicked accountant.
If you are doing cross-border digital services, platform sales, EU client work, or recurring invoices at pace, watch the VAT position early. Do not wait until you feel successful. VAT registration is a compliance trigger, not a reward.
There are also cases where voluntary registration makes commercial sense, especially where clients are VAT-registered businesses or where cross-border treatment creates a cleaner reporting setup. But voluntary VAT is not a lifestyle choice to make because somebody on a forum said it feels more professional. Run the numbers first.
Self-insurance
This is the least glamorous part and one of the most important. Self-insurance in Bulgaria means exactly what it sounds like: if you are self-employed, the system expects you to fund your own social contributions. Pension, health coverage, and related obligations do not pay themselves. They also do not disappear because you are between invoices.
People sometimes describe the ET route as low-cost. That is only half true. The setup can be light. Ongoing compliance is still real. Monthly contributions, periodic declarations, annual reconciliation, and planning around fluctuating income all sit in the background. Quietly. Persistently.
A decent working mindset looks like this:
- treat social contributions as a fixed operating cost, not optional money
- forecast quarterly tax obligations before cash gets tight
- coordinate your accountant, especially if foreign clients or mixed revenue streams are involved
If you are a non-EU resident, self-insurance and residence compliance can also interact in ways you should not treat casually. Legal presence, local administrative status, and tax/social records often need to tell one coherent story.
Follow post-registration duties
The ET is easy to romanticize right up until the first real reporting cycle.
After registration, you are not finished. You have post-registration obligations around tax registration, social insurance position, bookkeeping, invoicing discipline, annual filings, and where relevant VAT returns and periodic declarations. Bulgaria is not unusually cruel here, but it is rigid enough that missed deadlines cost money and nerves.
Many small operators learn this the clumsy way. They register, start billing clients, maybe even open the bank account, and assume the rest can be improvised. Then the accounting reality arrives. The National Revenue Agency expects proper declarations. Social insurance status has to be handled. Business records must be preserved. Annual tax return timing matters. If you hire employees, the burden jumps immediately.
And yes, you typically want local accounting services even for a small ET, especially if you are a foreign founder. Bulgarian forms, tax office practice, social security adjustments, and language issues make DIY compliance more expensive than it looks. Cheap self-confidence has ruined more than one otherwise viable small business.
There is another practical duty people underrate: contract hygiene. If you are trading as an ET, your contracts, invoices, bank details, and client onboarding documents should match the registered identity precisely. Sloppy naming across documents creates friction with banks, counterparties, and sometimes tax review. Again, not exciting. Very real.
The banking piece deserves a quick reality check too. Registration does not guarantee smooth banking. Banks in Bulgaria can be perfectly functional and perfectly cautious at the same time. If your activity is cross-border, digital, crypto-adjacent, marketing-heavy, outsourcing-based, or just difficult to explain in one clean paragraph, expect questions. Proof of address, source of funds, expected turnover, contracts, websites, client profile. Adult paperwork. Same story as with companies, really.
When should you choose an EOOD instead?
Usually sooner than optimistic founders think.
If your activity carries meaningful liability, if you want a cleaner company formation path, if tax optimization matters beyond the headline, if you plan to employ people, work with investors, sign larger contracts, or build something you may later sell, the EOOD tends to be the adult choice. Bulgaria’s all-inclusive appeal to foreign entrepreneurs is real, especially with its EU market access and 10% corporate tax, but that advantage shows up more cleanly inside a proper limited liability structure.
An ET is fine for a narrow solo operation. It is not a magic shortcut. Once the activity starts carrying contractual weight, receivables, payroll, inventory, loans, or regulatory exposure, unlimited personal liability turns from abstract legal language into actual risk concentration in one human being. You.
A quick comparison makes the point cleaner:
| Question | ET | EOOD |
|---|---|---|
| Separate legal entity | No | Yes |
| Personal asset protection | No real shield | Yes, if properly maintained |
| Startup capital | No minimum capital in practice | Minimal and manageable |
| Tax image | Personal taxation route | 10% corporate tax plus dividend layer where relevant |
| Investor / scaling logic | Poor fit | Stronger fit |
| Best for | Low-risk solo activity | Serious operations, foreign founders, scalable structures |
This is why many advisors quietly steer international investors away from ET unless there is a very specific reason to use it. The EOOD is simply more adaptable. More transparent for counterparties. More natural for incorporation, compliance, and later restructuring. If you are building anything beyond a lean solo practice, the ET often saves a little at the front and costs more in strategic flexibility later.
FAQ
Can a foreigner open a sole proprietorship in Bulgaria?
Sometimes yes, but the answer depends heavily on nationality and residence status. EU nationals usually have a more workable path. Non-EU individuals often need the right residence basis before the registration process becomes realistic. Immigration and business law are linked here.
Is an ET the same as freelancing in Bulgaria?
No. ET is a legal commercial registration. Freelancing is a broad work style. A freelancer may operate as an ET, under a self-employed professional basis, or through an LLC. Same economic activity, different legal shell.
Does an ET get Bulgaria’s 10% corporate tax?
No. That 10% rate is associated with companies subject to corporate income tax. An ET is generally taxed under personal income tax rules, and common guidance points to a 15% rate on ET taxable income. The exact numbers should be confirmed with an accountant because facts matter.
Is there limited liability?
No. The owner has unlimited liability. Business debts can reach personal assets, including bank balances and potentially real estate or vehicles, depending on the case and applicable property rules.
Do I need VAT registration?
Not immediately in every case, but mandatory VAT registration can arise once turnover crosses the legal threshold, commonly BGN 100,000 over the relevant period. Certain activities may trigger earlier analysis, especially in cross-border services.
Do I need an accountant?
Legally, the question can be narrower. Practically, yes, you usually do. Especially if you are a foreign founder, have cross-border clients, or are unsure whether you should be an ET at all.

Conclusion
The sole proprietorship in Bulgaria is attractive for the same reason many simple structures are attractive: low entry cost, limited setup friction, and a feeling that you can just get moving. Sometimes that is exactly right. A solo operator, low-risk activity, predictable client work, decent records, no illusions. Fine. Use it.
Still, the ET is one of those structures that looks better from a distance than from inside the liability clause. It is not a separate company. It does not protect your personal property. It does not automatically deliver the tax advantages people associate with Bulgaria’s corporate regime. And it does not excuse weak compliance.
So the honest answer is annoyingly unsentimental. If you need a lightweight way to trade as one person in Bulgaria, the ET can work. If you need liability protection, stronger tax planning, easier scaling, or a cleaner vehicle for international business, choose an EOOD and spare yourself the later repair job. That is usually the more professional decision. The cheaper route is not always the cheaper outcome.
