Many people moving to Bulgaria hear about the country’s 10% flat personal income tax rate and assume that everything else will be equally simple. In reality, relocating can create unexpected tax obligations, especially if you continue working for a foreign employer, own property abroad or receive income from multiple countries.
Preparing before you move can prevent problems with tax residency, double taxation, health insurance and reporting deadlines. Here are six important things to sort out if you are planning to relocate to Bulgaria in 2027.
1. Know When You Become a Bulgarian Tax Resident
Your tax residency determines how Bulgaria may tax your income. Under Bulgarian legislation, several criteria are relevant, including spending more than 183 days in the country during any 12-month period, maintaining a permanent address and having your centre of vital interests in Bulgaria. Your centre of vital interests depends on personal and economic connections, including where your family lives, where you work and where your main interests are located.
Bulgarian tax residents are generally subject to taxation on worldwide income, not only income earned in Bulgaria. However, applicable international tax treaties can affect residency determination and provide relief from double taxation. The 183-day rule is therefore not the only factor to consider.
Before relocating, review:
- Your planned arrival date and expected length of stay.
- Where your family and permanent home will be located.
- Whether you will continue working for a foreign employer.
- Whether an applicable double taxation treaty affects your situation.
For example, moving your family and main economic activities to Bulgaria may affect your tax status even before you have spent six months in the country.
2. Close Things Properly in Your Previous Country
Moving to Bulgaria does not automatically end your tax residency in your previous country. Depending on local legislation, you may need to notify the tax authorities, submit a departure return or provide evidence that your circumstances have changed. Without proper preparation, two countries may initially consider you a tax resident during the same period.
Before leaving, collect your previous tax returns, employment contracts, income statements and proof of foreign taxes paid. Keep documentation confirming your relocation date, particularly if you retain property, investments or employment connections abroad. An applicable double taxation treaty may help resolve conflicting residency claims and determine how particular income should be taxed.
The important point is to review your previous tax obligations before departure rather than assuming they disappear when you change your address.
3. Get Your Bulgarian Identification and Registration Documents
Administrative requirements depend on your nationality and purpose of residence. EU citizens can generally stay in Bulgaria for up to three months using a valid passport or national identity card. Longer stays require compliance with applicable residence registration rules. Non-EU citizens may need an appropriate visa and residence permit, depending on their individual circumstances.
You should also determine which Bulgarian personal identification number applies to you, such as an EGN or LNCh. This information may be necessary when dealing with employers, banks and public authorities. Registration with the National Revenue Agency (NRA) depends on your activities and is not automatically required simply because you have moved to Bulgaria.
Before starting work, make sure you understand:
- Which residence documents you need.
- Which personal identification number applies to you.
- Whether you need tax or self-employment registration.
- Which additional obligations apply if you start a business.
4. Arrange Your Health Insurance
Health insurance is often overlooked during international relocation. Your obligations depend on your employment arrangements and the social security legislation applicable to your circumstances. Employees working under Bulgarian contracts generally have insurance obligations handled through their employers, while self-employed individuals may need to arrange their own registration and contributions.
If you continue working remotely for a foreign company, additional rules may apply. Within the European Union, social security coordination determines which country’s insurance system is responsible. In certain cases, an A1 certificate may be relevant when establishing applicable coverage.
Individuals required to pay Bulgarian health insurance contributions themselves under the relevant rules may need to submit Declaration Form No. 7. Under current legislation, more than three unpaid required monthly contributions within a 36-month period can interrupt public healthcare insurance rights for individuals responsible for their own contributions.
Before relocating, confirm your existing coverage, determine which insurance system applies and check whether Bulgarian registration is necessary. Do not assume that foreign health insurance automatically remains sufficient after moving.
5. Remember That Foreign Income Still Counts
One common mistake is assuming that income received from another country is automatically excluded from Bulgarian taxation. Bulgarian tax residents are generally taxable on worldwide income, subject to applicable exemptions and international agreements. This may include salaries from foreign employers, freelance payments, rental income, dividends and certain investment transactions.
Different income categories follow different rules. Some may require annual reporting, while others may qualify for exemptions or tax relief. If no Bulgarian payer is responsible for withholding tax, you may need to calculate and pay certain taxes yourself, including advance payments where applicable.
The following table highlights common situations:
| Income Type | What Should Be Reviewed |
|---|---|
| Foreign employment income | Tax residency, place of work and withholding obligations. |
| Freelance income | Registration, advance taxation and insurance requirements. |
| Foreign rental income | Reporting obligations and applicable treaty relief. |
| Dividends and investments | Income classification, exemptions and declaration requirements. |
Keep foreign tax certificates, contracts, payment records and investment statements throughout the year. These documents may be essential when preparing your Bulgarian tax return or applying double taxation relief.
6. Know Your First Tax Filing Deadline
Income received during 2027 that requires annual reporting will generally be included in the relevant Bulgarian personal income tax return. The standard statutory filing deadline for individuals is 30 April of the following year. For income received in 2027, the filing period will therefore be in 2028, subject to applicable rules for non-working days and any legislative changes. Different deadlines may apply to certain taxpayers.
If tax has already been paid abroad, relief may be available under Bulgarian legislation or an applicable double taxation treaty. Supporting documents may be required, so collecting them throughout the year is much easier than requesting missing certificates shortly before filing.
Your first-year records should include:
- Annual employment income statements.
- Documents confirming foreign taxes paid.
- Rental and freelance income records.
- Dividend and investment statements.
- Relevant tax residency certificates.
Practical Example: Moving to Bulgaria While Working for a German Company
Imagine moving to Sofia in March 2027 while continuing to work remotely for a German employer. By autumn, you may have spent more than 183 days in Bulgaria. This is an important factor when assessing Bulgarian tax residency, although your complete circumstances and the Bulgaria-Germany tax treaty must also be considered.
Your employment income may require assessment under Bulgarian tax rules, and German payroll withholding does not automatically settle potential Bulgarian obligations. Social insurance must also be examined separately, particularly when the work is physically performed in Bulgaria. Reviewing these arrangements before relocating can help prevent incorrect withholding, reporting problems and administrative complications.
What Should You Check Before Moving to Bulgaria?
- Whether and when you may become a Bulgarian tax resident.
- Whether your previous country requires departure notification or additional tax reporting.
- Which residence and identification documents you need.
- Which country’s health and social insurance system applies.
- Whether foreign income may need to be declared in Bulgaria.
- Which documents you should collect for your first annual tax return.
Moving to Bulgaria in 2027 can be much easier when these matters are organised in advance. The right approach depends on your employment, family circumstances, foreign income and financial connections with other countries.
