Moving to Bulgaria as a digital nomad can create an attractive tax position, but immigration status, tax residence, and social security are separate questions. A residence permit does not automatically determine where tax is due, and spending fewer than 183 days in Bulgaria does not always prevent Bulgarian tax residence.

This guide explains the main tax issues digital nomads should review before relocating to Bulgaria in 2026.

Tax residence and social-security treatment depend on the individual's facts, contracts, business structure, and applicable international agreements. Obtain advice before changing residence or invoicing arrangements.

Bulgaria Digital Nomad Taxes at a Glance

When Does a Digital Nomad Become Tax Resident in Bulgaria?

Bulgarian tax residence is not based only on the visa or residence card a person holds. A person may be treated as a Bulgarian tax resident when, among other factors, they:

• spend more than 183 days in Bulgaria during a 12-month period
• have a permanent address in Bulgaria, unless their centre of vital interests is outside the country
• have their centre of vital interests in Bulgaria

The centre-of-vital-interests test considers where a person's closest personal and economic connections are located. Relevant facts can include their home, family, work, business management, property, and habitual place of living.

Where Bulgaria and another country both consider a person resident, an applicable double-tax treaty may use tie-breaker tests to determine treaty residence. These commonly examine the permanent home, centre of vital interests, habitual abode, and nationality in sequence.

What Income Is Taxed in Bulgaria?

Bulgarian tax residents are generally taxed on worldwide income, subject to exemptions and relief under domestic law and tax treaties. Non-residents are generally taxed only on income from Bulgarian sources.

The headline personal income-tax rate is 10% for many common categories of income. The actual taxable base and filing treatment depend on whether the income is salary, independent professional income, business income, dividends, rent, capital gains, or another category.

Foreign income may still need to be declared in Bulgaria even where tax has already been paid abroad. A double-tax treaty or Bulgarian domestic relief may prevent the same income from being taxed twice, but the relief usually must be claimed and documented correctly.

Option 1: Work as an Independent Professional

Some digital nomads register in Bulgaria as self-insured persons carrying on a recognised independent or liberal profession. This can be suitable for consultants, designers, developers, and other professionals who work personally for clients.

Depending on the activity, a statutory expense deduction may reduce the taxable base. A 25% deduction is common for certain independent professional income, producing an effective income-tax rate of 7.5% before social-security contributions. Different activities may receive a different deduction or treatment, so eligibility should be confirmed.

The independent-professional route generally involves:

• registration with the relevant Bulgarian registers and revenue authority
• issuing compliant invoices and maintaining records
• making advance tax payments where required
• paying health and social-security contributions
• filing an annual personal income-tax return

This structure is comparatively simple, but the individual normally has unlimited personal liability for the activity.

Option 2: Operate Through a Bulgarian Company

A digital nomad may instead establish a Bulgarian single-member limited liability company, known as an EOOD. A company can provide limited liability, a clearer commercial structure, and greater flexibility when working with larger clients or hiring staff.

A Bulgarian company generally pays 10% corporate income tax on taxable profit. Dividends distributed to an individual are generally subject to a 5% dividend tax. When all after-tax profit is distributed, the combined headline burden is approximately 14.5%, before salary taxes, social security, accounting costs, and other adjustments.

A company also brings additional compliance duties, including:

• double-entry bookkeeping
• annual corporate tax and financial reporting
• payroll and social-security compliance where applicable
• VAT assessment and registration when required
• documentation of transactions with related parties

Forming a company does not by itself make all income corporate income. Contracts, actual working arrangements, and how money is withdrawn from the company must be structured and documented correctly.

Independent Professional or Company?

There is no universal income level at which one structure becomes better. The right choice depends on expenses, social-security treatment, risk, clients, planned reinvestment, and how much profit will be distributed.

Social Security and Health Insurance

Tax residence and social-security coverage are related but distinct. The applicable system can depend on nationality, employment status, employer location, residence, and international social-security rules.

EU, EEA, and Swiss rules may allow a person temporarily working in Bulgaria to remain covered in another member state's system if they hold the appropriate A1 certificate. Other bilateral social-security agreements may also affect coverage.

Someone registering as self-insured in Bulgaria normally pays Bulgarian contributions on an insurable-income base within statutory minimum and maximum limits. Annual equalisation or additional contributions may apply. These amounts and rates change, so current figures should be confirmed before budgeting.

VAT for Digital Nomads

VAT can apply even when all clients are outside Bulgaria. Registration may become mandatory because of turnover, services supplied to EU businesses, cross-border purchases, or other transactions.

The place-of-supply rules determine where a service is taxed. For business-to-business services, the customer's location and reverse-charge rules are often important. Consumer services, digital services, and e-commerce can follow different rules.

Review VAT obligations before issuing the first invoice from Bulgaria. Late registration can lead to tax assessments, interest, and penalties.

Foreign Companies and Management Risk

A digital nomad who owns or manages a foreign company from Bulgaria should assess whether their activity creates Bulgarian tax exposure for that company. Relevant issues may include:

• where the company's effective management takes place
• whether the person creates a Bulgarian permanent establishment
• transfer pricing between the owner and the company
• payroll and social-security obligations
• the treatment of salary, management fees, and dividends

Keeping a foreign company registered abroad does not guarantee that the company has no Bulgarian obligations.

Double Taxation and Treaty Relief

Bulgaria has a broad network of double-tax treaties. Depending on the treaty and income type, double taxation may be relieved through an exemption, foreign-tax credit, or allocation of taxing rights to one country.

Practical steps may include obtaining a Bulgarian tax-residence certificate, retaining proof of foreign tax paid, notifying a former country of residence, and filing the required declarations. Treaty protection is not always automatic.

Practical Relocation Checklist

Before or shortly after moving to Bulgaria:

1. Assess tax residence in Bulgaria and the country you are leaving.
2. Review the tax treaty and any social-security agreement.
3. Choose an appropriate operating structure.
4. Register with the Bulgarian authorities where required.
5. Review VAT before invoicing clients.
6. Set up bookkeeping and retain contracts, invoices, and bank records.

Frequently Asked Questions

When does a digital nomad become tax resident in Bulgaria?

Tax residence can arise from spending more than 183 days in Bulgaria during a 12-month period or from other factors, including a permanent address and centre of vital interests. An applicable double-tax treaty may affect the result.

What is Bulgaria's personal income-tax rate?

A flat 10% rate applies to many common categories of personal income, but the taxable base, deductions, exemptions, and filing treatment depend on the income type.

Should a digital nomad register as an independent professional or form a company?

The appropriate structure depends on the activity, expenses, liability risk, clients, social-security position, and plans for retaining or distributing profit. There is no universal income threshold that determines the best option.

Can foreign income be taxed in Bulgaria?

Yes. Bulgarian tax residents are generally taxable on worldwide income. Double-tax treaties and domestic relief may prevent double taxation, but foreign income and tax paid abroad may still need to be declared.

Do digital nomads need Bulgarian VAT registration?

Possibly. VAT registration can be triggered by turnover, services to EU businesses, cross-border purchases, or other transactions, even when clients are outside Bulgaria.
