Freelancer in Bulgaria: Registration and Tax Guide

Yes, you can work legally as a freelancer in Bulgaria and invoice clients in Bulgaria, elsewhere in the EU, or outside the EU. For many consultants, developers, designers, marketers, and creators, the usual route is registration as a person exercising a free profession and as a self-insured person.

The headline tax is attractive, but the setup is not simply "7.5% tax and no paperwork." Social contributions, VAT, tax residence, immigration status, and the way you work with foreign clients all matter. This guide explains the practical position in 2026.

Registration, tax residence, immigration, VAT, and social-security coverage are separate questions. Confirm all five before moving or changing your contracts.

What "freelancer" means under Bulgarian law

"Freelancer" is a useful everyday term, but it is not one universal Bulgarian legal status. The closest common category is a person exercising a free profession, called svobodna profesiya. The National Revenue Agency describes these people as self-insured persons who perform professional work on their own account and are not registered as sole traders.

The category expressly includes professions such as consultants, translators, architects, engineers, medical specialists, educators, artists, and scientists. Other knowledge-based work may qualify when its character and expertise are similar. Selling professional services is different from trading goods or working under conditions that are really employment.

Some professions are regulated. A doctor, architect, lawyer, or other regulated professional may need diploma recognition, membership, a licence, or another approval before starting. Registration as a freelancer does not replace that professional authorisation.

Is Bulgaria a good base for your freelance career?

Bulgaria can work well when you personally deliver services, have relatively low actual expenses, want an EU base, and prefer simpler administration than a limited company. A qualifying freelancer can use statutory expenses instead of deducting every ordinary business cost separately.

It is less compelling when the activity carries meaningful liability, depends on a team, needs large reinvestment, or has substantial real expenses. The 25% statutory deduction may be poor value if genuine costs are much higher. Some corporate clients also prefer a limited company.

Moving only on paper is risky. Bulgarian tax residence can arise through time spent in the country, a permanent address, or the centre of your personal and economic interests. If another country also treats you as resident, the applicable double-tax treaty must be checked. Our digital-nomad tax guide covers those residence tests in more detail.

Under EU work rules, EU citizens may work as self-employed people in Bulgaria without a work permit. Non-EU nationals should not assume that BULSTAT registration creates a right to live or work here. Depending on the case, a self-employment permit, type D visa, and residence permit may be required. The EU Immigration Portal summarises the non-EU self-employed route. A different remote-work route is discussed in our Bulgarian digital nomad visa guide.

How to register as a freelancer in Bulgaria

1. Confirm that the activity qualifies

Describe what you will actually sell, how you will work, and whether the profession is regulated. This first decision affects registration, tax, licensing, and VAT. Do not choose the free-profession label only because the tax headline looks favourable.

2. Prepare your Bulgarian identification and address

Foreign applicants need identification accepted by the Bulgarian authorities. The precise documents depend on nationality and residence status. Regulated professionals also need evidence of their qualification or right to practise.

3. Register in BULSTAT

Individuals exercising a free profession are entered in the BULSTAT Register. The Registry Agency states that applications must be submitted within seven days after the registration obligation arises. The resulting BULSTAT code is used on business documents.

4. Declare the start of self-insured activity

After BULSTAT, notify the National Revenue Agency of the start of activity and the chosen scope of social insurance. The NRA deadline is seven days from starting the work. Filing late can restrict insurance choices, so the declared start date should match the real beginning of the activity.

5. Check VAT before the first cross-border invoice

Do this before invoicing, not after crossing a turnover threshold. Article 97a can require earlier registration for services supplied to VAT-registered EU businesses or for certain services received from foreign suppliers.

6. Set up invoices and records

Invoices should identify both parties, describe the service, show the date and amount, and contain the required VAT wording. Keep contracts, payment records, and evidence of each client's location and business status. Set up the monthly declarations and tax calendar before the first deadline.

What will you actually pay in tax and social security?

For most qualifying free professions, the Ministry of Finance confirms statutory expenses equal to 25% of income. The remaining 75% is reduced by eligible compulsory social contributions and taxed at 10%. On that simplified basis, income tax before social contributions is 7.5% of gross income.

The example is not a total-cost calculation. Social and health contributions are additional, and paid compulsory contributions reduce the income-tax base. Some professions use a different statutory deduction. Employment income, foreign insurance coverage, pension status, interruptions in activity, and income earned for only part of the year can change the result.

2026 social-insurance limits. For 1 January through 31 July 2026, the monthly base for self-insured people ran from EUR 550.66 to EUR 2,111.64. From 1 August through 31 December, it runs from EUR 620.20 to EUR 2,300, according to the National Social Security Institute. Contributions are paid in advance and reconciled annually against the applicable final insurable income.

Social contributions and the monthly declaration are generally due by the 25th of the following month. Advance income-tax declarations and payments are generally due after the first three quarters, with no equivalent fourth-quarter advance payment. The annual personal income-tax return and social-security reconciliation are generally due by 30 April of the following year.

Working with EU clients from Bulgaria

A Bulgarian freelancer can generally provide services across the EU without opening a company in every customer's country. Rules for the specific service still apply, as do VAT, tax, and social-security checks.

For many business-to-business services, the place of supply is where the EU business customer is established and the customer accounts for VAT under the reverse charge. A Bulgarian supplier covered by Article 97a normally needs VAT registration and may need VIES reporting even when domestic turnover is below EUR 51,130. The NRA's VAT registration guidance explains both grounds. Services to consumers, digital services, property-related work, events, and other exceptions need separate analysis.

Social security follows its own rules. A freelancer temporarily moving from another EU or EEA country or Switzerland may remain covered there with an A1 certificate. Someone working in several countries is normally covered by one system under EU coordination rules. Tax residence does not answer that question.

Keeping a company registered in another country also needs care. Managing it from Bulgaria may create Bulgarian corporate residence, permanent-establishment, payroll, or transfer-pricing issues. A foreign registration address alone does not settle where the company is taxed.

When an EOOD company may be a better fit

A Bulgarian EOOD is a separate limited-liability company. It usually brings full accounting and more administration, but it can suit freelancers who hire, use subcontractors, retain profit, carry contractual risk, or need a structure accepted by larger clients. It also lets the business deduct documented costs rather than relying on a statutory percentage.

There is no reliable income level at which everyone should switch. Compare personal tax, social contributions, corporate and dividend tax, accounting, liability, actual expenses, and how money will be withdrawn. Our company-registration guide explains the EOOD formation process.

A checklist before relocating

1. Confirm that your work qualifies as a free profession.
2. Check immigration and any professional licence before starting.
3. Assess tax residence in Bulgaria and the country you are leaving.
4. Review EU or treaty social-security coverage and obtain an A1 if applicable.
5. Choose between freelancer status and an EOOD using your real numbers.
6. Plan BULSTAT and NRA filings around the genuine activity start date.
7. Review Article 97a and other VAT grounds before the first invoice.
8. Put contracts, invoicing, records, and deadline reminders in place.

Frequently Asked Questions

How long does it take to register as a freelancer in Bulgaria?

A straightforward registration can be completed quickly, but timing depends on the documents, residence status, professional qualifications, and filing method. BULSTAT and NRA each have their own seven-day deadline, so the activity start date must be planned carefully.

How much income tax does a freelancer pay in Bulgaria?

Qualifying free-profession income is generally taxed at 10% after the applicable statutory expense deduction and compulsory social contributions. A common 25% statutory expense deduction produces a 7.5% income-tax rate on gross income before social contributions, but it is not the freelancer's total tax and insurance burden.

Can a Bulgarian freelancer invoice foreign clients?

Yes. A Bulgarian freelancer can invoice clients in other EU countries and outside the EU. The client's business status, location, and type of service determine the VAT treatment, invoice wording, and reporting obligations.

Do I need Bulgarian VAT registration for EU clients?

Possibly. Services supplied to VAT-registered businesses in another EU member state can trigger registration under Article 97a before the first relevant supply, even when turnover is below Bulgaria's general VAT threshold.

Is it better to work as a freelancer or through an EOOD company?

Freelancer status often suits a person selling their own expertise with modest costs and risk. An EOOD may be better when limited liability, employees, subcontractors, retained profit, substantial actual expenses, or corporate procurement requirements matter.
