Freelancing in Bulgaria: Taxes, Social Security, VAT and Legal Setup
A practical guide for independent professionals, consultants, creators and remote workers who want to operate from Bulgaria without building their business on tax-rate headlines and administrative guesswork.
You can freelance from Bulgaria either as an individual- most commonly as a registered free profession– or through a Bulgarian company such as an EOOD. Many eligible self-employed professionals use a 25% statutory expense deduction and pay 10% income tax on the remaining annual tax base after deductible mandatory social security contributions. However, the right structure also depends on the commercial nature of the activity, actual costs, income level, clients, VAT exposure, immigration status and where the work is genuinely performed and managed.
The 10% headline is not your total cost
Income tax, social security and VAT are three different questions. A freelancer who advances insurance on the minimum base may still owe additional contributions after the annual equalisation. A low headline tax rate therefore does not mean that the total burden is 7.5% or 10%.
Start with the legal form
“Freelancer” is not a Bulgarian legal status
Freelancer is a useful business description, but Bulgarian legislation does not treat it as a single legal form. Before calculating tax, you must identify the form through which the activity is carried on.
A software developer, designer, translator, architect, consultant, photographer, therapist or content creator may all describe themselves as freelancers. Their Bulgarian registration and tax treatment can nevertheless differ because of professional qualifications, the commercial character of the activity, intellectual-property income, regulated-profession rules and the way services are delivered.
Free profession
Often suitable for independent knowledge-based or creative services that fall within the statutory definition and are exercised personally.
EOOD or OOD
A separate legal entity with corporate accounting, 10% corporate tax and a second tax layer when profit is distributed as a dividend.
Commercial activity
Repeated organised sales, online courses, e-commerce or business-like operations may require analysis beyond a simple free-profession registration.
Registration does not cure the wrong classification
Being entered in BULSTAT as a free professional does not by itself prove that every activity qualifies for that treatment. The substance of the work, the applicable professional rules and the manner in which the business is organised remain decisive.
Foreign professionals
Can a foreign citizen work as a freelancer in Bulgaria?
Nationality, residence, work authorisation, professional registration and tax registration are separate layers. An EU, EEA or Swiss citizen generally has a different immigration and labour-mobility position from a third-country national. Tax registration alone does not create a right to reside or work in Bulgaria.
Freedom of movement helps- but does not replace registration
You still need to analyse residence registration, the professional form, BULSTAT, social security, income tax and VAT. Regulated professions may require recognition or membership procedures.
A work and residence basis may be required first
Bulgaria has a specific freelance-permit procedure for certain third-country nationals. The Employment Agency lists requirements including an activity plan, evidence of experience and funds, and Bulgarian language proficiency at least at B1 level. Another valid immigration basis may lead to a different analysis.
Owning a Bulgarian company is also not automatically the same as holding permission to perform work in Bulgaria. If immigration status is uncertain, resolve it before relying on a tax or company structure.
The central decision
Free profession or Bulgarian company?
Neither form is universally cheaper. A free profession can be administratively lean and may benefit from statutory expenses, but social security is subject to annual equalisation. A company can deduct documented business expenses and retain profit, but it brings full bookkeeping, corporate compliance and rules for extracting money personally.
| Question | Free profession | EOOD company |
|---|---|---|
| Legal identity | The individual carries on the activity personally. | The company is a separate legal person. |
| Typical tax base | Income less applicable statutory expenses and deductible insurance. | Accounting profit adjusted under corporate tax rules. |
| Headline income tax | 10% personal income tax. | 10% corporate tax; generally 5% dividend tax upon distribution to an individual. |
| Expenses | Usually statutory rather than actual expenses; the percentage depends on the income category. | Documented business expenses are recognised subject to corporate tax rules. |
| Administration | Usually lighter, but records, invoices, declarations and insurance remain necessary. | Double-entry bookkeeping, annual financial statements and corporate filings. |
| Liability | No separate limited-liability shield for the activity. | Limited liability in principle, subject to statutory exceptions and managerial responsibility. |
| Often attractive when | The work is genuinely personal, eligible and has relatively low actual costs. | The activity has higher costs, commercial risk, reinvestment, staff, partners or growth plans. |
Compare the full cash result, not two tax percentages
The proper comparison includes final social security, corporate and dividend tax, remuneration to the owner, actual expenses, VAT recovery, administration, liability and how much cash must be withdrawn personally.

Correct order matters
How self-employed registration works
For a typical eligible free professional, registration is a sequence rather than one form. The exact documents depend on nationality, profession and whether the person already has a Bulgarian personal number or another local registration.
- Confirm the right to reside and work. Third-country nationals should not assume that tax registration or company ownership supplies the missing immigration permission.
- Classify the activity. Confirm that it fits a free profession and check whether it is regulated, licensed or better characterised as commercial activity.
- Register in BULSTAT. The Registry Agency states that a free professional should register within seven days of commencing the activity.
- Declare the start of self-insurance. The relevant declaration to the National Revenue Agency is generally due within seven days of starting, resuming, interrupting or terminating the activity.
- Review VAT before the first cross-border transaction. Article 97a may require registration before a foreign-platform fee or a qualifying EU B2B service- well before the normal turnover threshold.
- Set up invoices and records. Decide how contracts, invoice numbering, bank receipts, platform statements, expense evidence and monthly cut-offs will be maintained.
Do the VAT check before buying advertising or platform services
A freelancer can create an Article 97a exposure by receiving services from a supplier established abroad- for example certain platform commissions, software, hosting or advertising services. Waiting until annual tax-return season may already be too late.

Personal income tax
How freelance income is taxed
For many individuals exercising an eligible free profession, taxable business income is calculated by reducing gross income by a 25% statutory expense deduction. Mandatory social security contributions deductible under the Personal Income Tax Act then reduce the annual tax base, to which the 10% personal income tax rate is applied.
The 25% deduction is not universal. Different percentages or rules can apply to royalties and licence income, qualifying artistic or authorship income, legal practice, agriculture and activities treated as those of a merchant. The contract label does not determine the category by itself.
Gross professional income
− applicable statutory expenses
− deductible mandatory social security contributions
= annual taxable base
× 10% = personal income tax
Advance tax and annual reporting
Advance income tax is generally determined for the first three quarters. Where the payer does not withhold it- commonly the case with foreign clients- the freelancer normally calculates, declares and pays it. The usual quarterly deadlines are 30 April, 31 July and 31 October. No standard advance payment is made for the fourth quarter. The annual personal income tax return and final payment are generally due by 30 April of the following year.
Gross receipts are not always the bank payout
If a platform deducts its commission before transferring the balance, the correct accounting starting point may be the gross client revenue with the platform fee recorded separately- not only the net amount received in the bank account.

Often the largest cost
Social security for freelancers in 2026
A registered self-employed person usually selects an advance monthly insurance base between the statutory minimum and maximum. Contributions are paid monthly, but the final base is reconciled through the annual tax return against income from the relevant activity, subject to the monthly statutory ceiling.
| Period in 2026 | Minimum monthly base | Maximum monthly base |
|---|---|---|
| 1 January–31 July | €550.66 | €2,111.64 |
| 1 August–31 December | €620.20 | €2,300.00 |
The commonly quoted combined rates are 27.8% for pension and health coverage, or 31.3% where the self-employed person also opts into the general sickness and maternity fund. For people born after 31 December 1959, part of the pension component may be directed to a universal pension fund, unless the lawful alternative applies.
Assume an eligible free professional works throughout 2026, earns €36,000, uses the standard 25% statutory expense deduction and has no other insured income. Income after the statutory deduction is €27,000, or €2,250 per activity month.
For annual equalisation, the first seven months are capped at €2,111.64 and the remaining five months use €2,250, which is below the €2,300 ceiling. The illustrative final insurance base is therefore approximately €26,031.48. At a combined 27.8% rate, contributions are approximately €7,236.75. After deducting those contributions, the illustrative 10% income tax is approximately €1,976.33.
Illustrative combined tax and insurance: approximately €9,213.08- not €2,700 and not merely 7.5% of revenue.
The example is deliberately simplified
Existing employment, insured income from another source, activity for only part of the year, pension status, sickness-and-maternity election, another EU social-security system or treaty coordination can materially change the calculation.
More than one registration test
VAT for Bulgarian freelancers
In 2026, the national threshold for mandatory VAT registration is €51,130 of annual turnover in Bulgaria under the applicable calendar-year rules. But the threshold is only one VAT test. Cross-border services, foreign platform charges, intra-EU transactions and particular activities can create earlier or separate obligations.
Article 96
Mandatory registration may arise when the relevant annual turnover in Bulgaria exceeds €51,130. The composition and timing of turnover must be monitored, not guessed from bank receipts.
Article 97a
Registration may be required before receiving certain services from a foreign supplier or before supplying general-rule B2B services to a business customer in another EU member state.
Voluntary registration
Voluntary full registration can sometimes be commercially useful, but its filing burden, pricing impact and input-tax position should be modelled first.
Article 97a is not ordinary full VAT registration
A person registered only under Article 97a generally does not obtain the normal right to deduct input VAT merely because of that registration. They may need to self-charge Bulgarian VAT on qualifying received services and file monthly VAT records. For qualifying B2B services supplied to business customers in other EU member states, the customer may account for VAT under the reverse-charge mechanism and the Bulgarian supplier may have VIES reporting obligations.
A foreign client does not automatically mean “no Bulgarian VAT”
You must identify the customer, whether they act as a business, where they are established, the exact service and any special place-of-supply rule. B2C digital services, event services, property-related services and other exceptions can produce a different answer and may involve OSS.

Invoices, platforms and evidence
EU clients, non-EU clients and payment platforms
Cross-border freelancing normally involves at least three parties: the professional, the real customer and a payment or marketplace platform. Their roles should not be merged. Stripe, Wise or PayPal may process money without becoming the customer. Upwork or Fiverr may have a more complex contractual role and may charge a separate platform service.
| Situation | Main questions | Typical documents |
|---|---|---|
| EU business client | Valid VAT status, place of supply, Article 97a, reverse charge and VIES. | Contract, VAT validation, invoice, delivery evidence and payment record. |
| Non-EU business client | Business status, establishment, service type and evidence supporting the VAT treatment. | Contract, company details, invoice, correspondence and bank or platform statement. |
| Foreign individual | B2C place-of-supply rule, service exception, digital-service rules and possible OSS exposure. | Customer location evidence, terms, invoice or sales record and payment data. |
| Marketplace or platform | Who is the contractual customer, who invoices whom, gross revenue, fees and reverse charge on the platform service. | Platform agreement, transaction report, fee invoice, client invoice and payout reconciliation. |
Reconcile the full transaction chain
The invoice, platform statement, fee document, currency conversion and bank payout should tell one consistent story. A net bank receipt alone is rarely enough for reliable tax and accounting treatment.

Where the person really lives
Tax residence comes before the tax rate
Registering as self-employed in Bulgaria does not automatically settle tax residence. Bulgarian domestic law considers factors including a permanent address, presence in Bulgaria for more than 183 days in a twelve-month period, assignment abroad by the Bulgarian state and the centre of vital interests. A permanent address alone may not make a person resident where their centre of vital interests is outside Bulgaria.
If two countries regard the same person as resident, the applicable double tax treaty may use tie-breaker tests such as a permanent home, centre of vital interests, habitual abode and nationality. The treaty analysis is fact-specific.
Worldwide income may enter the Bulgarian return
The fact that a customer, platform or bank account is abroad does not by itself remove income from Bulgarian taxation.
A foreign company creates extra questions
Managing a foreign company from Bulgaria can raise corporate residence, permanent establishment, payroll and social-security issues beyond the freelancer’s personal return.

Substance over contract labels
When a contractor begins to look like an employee
A document titled “independent contractor agreement” is not conclusive if the real relationship has the characteristics of employment. The risk is higher where the individual works under the client’s direction, follows fixed working time, is integrated into the organisation, uses the client’s tools, has little commercial independence and bears no genuine entrepreneurial risk.
- Control over how and when the service is performed
- Ability to work for multiple clients
- Own equipment and operating costs
- Commercial risk and responsibility for results
- Project or deliverable-based relationship
- Fixed working hours and workplace
- Ongoing managerial control
- Integration into the client’s internal hierarchy
- Paid leave or employee-like benefits
- Personal dependency on one organisation
A single foreign client is not automatically prohibited, but the complete working arrangement should be reviewed- especially when the freelancer previously worked for the same organisation as an employee.
Operational discipline
A practical compliance calendar
The precise filing set depends on VAT status, clients, payer type and insurance position. The following is a working framework for a typical active self-employed professional.
| Frequency | Typical obligation | Common deadline |
|---|---|---|
| Monthly | Advance social and health insurance; social-security data filing where applicable. | Usually by the 25th of the following month. |
| Monthly when VAT-registered | VAT return, ledgers, payment and VIES where relevant. | Generally by the 14th of the following month. |
| Quarterly | Advance personal income tax declaration and payment where the freelancer must account for it. | 30 April, 31 July and 31 October. |
| Annually | Personal income tax return, final tax and annual insurance equalisation. | Generally by 30 April of the following year. |
| Event-driven | BULSTAT, start/interruption/resumption of activity, VAT registration and changes in status. | Often within seven days or before the relevant transaction; check the specific rule. |
- Keep contracts and evidence identifying the real customer.
- Issue sequential and legally compliant invoices.
- Save platform reports and fee invoices- not only payout emails.
- Reconcile gross revenue, fees, currency conversions and bank receipts.
- Track VAT turnover and cross-border triggers throughout the year.
- Review the likely annual insurance equalisation before year-end.
Avoidable exposure
Ten common freelancer mistakes
- Assuming “freelancer” automatically qualifies as a free profession.
- Starting work before completing BULSTAT and self-insurance registration.
- Treating company ownership as permission to live or work in Bulgaria.
- Quoting the effective income-tax percentage while ignoring annual social-security equalisation.
- Waiting for the €51,130 threshold without checking Article 97a.
- Treating every foreign-client service as outside Bulgarian VAT.
- Recording only the net amount transferred by Upwork, Fiverr or another platform.
- Issuing the invoice to Stripe, PayPal or Wise when they merely process the payment.
- Ignoring tax residence because the client and bank account are abroad.
- Using an independent-contractor agreement for a relationship that operates like employment.
The best time for the review is before the first invoice
Most structural and VAT errors are cheaper to prevent than to correct after several months of transactions.

Frequently asked questions
What tax does a freelancer pay in Bulgaria?
Many eligible free professionals pay 10% personal income tax on the annual tax base after the applicable statutory expense deduction and deductible mandatory social-security contributions. Social and health insurance are additional and can be the larger cost.
Is the effective freelancer income tax really 7.5%?
A 25% statutory expense deduction can make the income-tax component equal to 7.5% of gross income before considering deductible insurance. But calling the whole burden 7.5% is misleading because social and health insurance must also be calculated and may be adjusted annually.
Do I need a Bulgarian company to freelance?
Not always. An eligible activity may be carried on as a registered free profession. A company may be more appropriate where there are substantial actual costs, commercial risk, staff, reinvestment, partners, organised sales or activities that do not fit the free-profession rules.
Can I register as self-employed if I am not Bulgarian?
Potentially, but tax registration must be separated from immigration and work authorisation. EU/EEA/Swiss citizens and third-country nationals follow different routes. Certain third-country nationals may need a specific freelance permit or another legal basis to work.
Do I need VAT registration below €51,130?
Possibly. Article 97a and other VAT provisions can require registration below the standard threshold- for example when receiving certain services from foreign suppliers or supplying qualifying general-rule B2B services to business customers in other EU member states.
Do I charge Bulgarian VAT to an EU company?
For many general-rule B2B services supplied to a business established in another EU member state, the place of supply is where the customer is established and reverse charge may apply. You must verify the customer’s status, register where required and consider VIES reporting. Exceptions exist.
Is Stripe or PayPal my customer?
Usually not when the service merely processes a payment. The invoice generally follows the underlying supply to the actual customer. Marketplace arrangements can be more complex, so the platform contract and transaction chain must be reviewed.
How are Upwork and Fiverr fees recorded?
Do not assume the bank payout is the entire revenue. The gross amount charged for the work and the platform fee commonly need to be identified separately. The foreign platform service may also create a Bulgarian reverse-charge and Article 97a issue.
Can I be employed and self-employed at the same time?
Yes, but insured income from employment affects the self-employed contribution calculation and the monthly maximum insurance base. The combined position should be reviewed month by month.
When do I become tax resident in Bulgaria?
The 183-day test is important but not the only factor. Permanent address and centre of vital interests also matter, and a double tax treaty may resolve dual-residence conflicts. Tax residence cannot be determined reliably from a residence card alone.
Can a Bulgarian accountant handle everything remotely?
Most tax, accounting, VAT and document workflows can be organised digitally. Immigration, regulated-profession procedures, banking or notarisation may still require particular documents or personal steps depending on the case.
