Moving to Bulgaria in 2027? 6 Tax Steps to Prepare

Moving to Bulgaria in 2027: Your Essential Tax Preparation Guide

Bulgaria attracts international professionals, entrepreneurs and remote workers with its straightforward personal income tax system. However, moving to another country involves more than registering a new address. Your employment arrangements, overseas investments and family circumstances can affect your tax obligations. The most important decisions often need to be made before you arrive. Whether you plan to relocate permanently, establish a business or continue working remotely for a foreign employer, these six practical steps will help you identify what needs to be checked before moving to Bulgaria in 2027.

1. Know When You Become a Bulgarian Tax Resident

Tax residency determines the extent of your Bulgarian income tax obligations. Under Bulgarian legislation, several criteria are relevant, including spending more than 183 days in Bulgaria within any 12-month period, having a permanent address and maintaining your centre of vital interests in the country. The applicable rules and any relevant international tax treaty must also be considered.

Your centre of vital interests reflects your personal and economic connections. Authorities may consider where your family lives, where you normally work and where your main interests are located. Bulgarian tax residents are generally taxable on worldwide income, although exemptions and treaty relief may apply. Simply obtaining a residence permit does not automatically determine your tax residency.

Before moving, review:

• Your intended arrival date and expected length of stay.
• Your family and permanent living arrangements.
• Your employment and business activities.
• Any applicable double taxation agreement.

Key point: Do not rely on the 183-day rule alone. Other circumstances may affect your status before you have spent six months in Bulgaria.

2. Resolve Your Tax Obligations in Your Previous Country

Leaving your home country does not automatically terminate your tax residency there. Depending on its legislation, you may need to notify the authorities, submit a departure return or provide evidence that you have established your life elsewhere. Keeping property, employment or significant family connections abroad may complicate the assessment.

If two countries consider you a tax resident during the same period, an applicable double taxation treaty may help determine your treaty status and the allocation of taxing rights. This is particularly important when you relocate in the middle of a tax year.

Before departure, collect previous tax returns, employment records, proof of foreign taxes paid and documents confirming your moving date. Keep copies of rental agreements and information about property or investments retained abroad. These records can help explain your circumstances to the relevant authorities.

3. Obtain the Correct Bulgarian Documents and Identification

Residence requirements depend on your nationality and the purpose of your stay. EU citizens can generally remain in Bulgaria for up to three months with a valid identity card or passport. Longer residence requires compliance with the applicable registration procedures. Non-EU citizens may need a visa and residence permit, depending on their nationality and circumstances.

You should also identify which personal identification number applies to your status, such as an EGN or LNCh. These identifiers are used in dealings with Bulgarian institutions, including tax and social security authorities.

Registration with the National Revenue Agency (NRA) is not automatically required for every newcomer. The obligations differ depending on whether you are an employee, freelancer, self-employed professional or business owner.

Before starting work, confirm:

• Which residence documents are required.
• Which identification number applies.
• Whether professional or tax registration is necessary.
• Whether your planned activities create additional reporting duties.

4. Arrange Your Health Insurance and Social Security

Health insurance should be reviewed before relocating, especially if you intend to keep working for an overseas company. Income tax and social security follow different rules, so paying income tax in Bulgaria does not automatically establish where you must be insured.

Employees of Bulgarian companies generally have insurance obligations administered through their employers. Self-employed individuals may need to register and arrange contributions themselves. For cross-border employment within the EU, social security coordination rules determine which national legislation applies. An A1 certificate may be relevant in certain circumstances.

Individuals required to pay Bulgarian health insurance contributions themselves under the applicable provisions may need to submit Declaration Form No. 7. The normal statutory deadline is the 25th day of the month following the start of the obligation. Under current rules, more than three unpaid required monthly contributions within a 36-month period can interrupt health insurance rights for individuals responsible for their own contributions.

Before cancelling existing coverage, confirm whether you will remain insured abroad or become subject to Bulgarian insurance legislation. This is particularly important for remote employees and people working in several countries.

5. Check How Bulgaria Treats Your Foreign Income

Moving to Bulgaria does not make income from other countries irrelevant. If you become a Bulgarian tax resident, foreign-source income may need to be considered for Bulgarian tax purposes. This can include overseas salaries, freelance fees, rental income, dividends and gains from investments.

The treatment depends on the income category, the applicable Bulgarian rules and any relevant international treaty. Some income may be exempt, while other income may require reporting or advance tax payments. Receiving money into a foreign bank account does not automatically remove Bulgarian reporting obligations.

The following table shows common situations:

Keep contracts, income statements, investment records and certificates of taxes paid abroad. These documents can be essential when preparing your Bulgarian tax return. If no Bulgarian payer is responsible for withholding tax, you may also need to calculate and pay certain taxes yourself, depending on the type of income.

6. Prepare for Your First Bulgarian Tax Filing Deadline

Income received during 2027 that requires annual declaration will generally be reported in the relevant Bulgarian personal income tax return in 2028. Under current rules, the standard statutory filing deadline for individuals is 30 April of the following year, with adjustments for non-working days where applicable. Certain taxpayer categories have different filing periods.

If tax was already paid abroad, relief may be available under an international treaty or Bulgarian law. The applicable method and supporting documentation depend on the circumstances. Start collecting records from the beginning of the year rather than waiting until the filing season.

Your document checklist should include:

• Employment and freelance income statements.
• Certificates confirming foreign taxes paid.
• Rental agreements and income records.
• Dividend and investment statements.
• Relevant tax residency certificates.

Practical Example: Moving to Sofia While Working for a German Company

Imagine that you plan to move to Sofia in March 2027 while keeping your employment contract with a German company. You intend to work remotely from Bulgaria, but your employer will continue processing payroll in Germany. By autumn, you may have spent more than 183 days in Bulgaria, making tax residency an important issue.

Your circumstances must be assessed under Bulgarian law and the Bulgaria-Germany tax treaty. Employment income, payroll withholding and social security require separate consideration. Continuing German payroll deductions does not automatically mean all Bulgarian obligations have been satisfied.

The practical lesson is to review your employment arrangements before relocating. Addressing possible conflicts early is easier than correcting them after your first tax filing.

What Should You Check Before Moving to Bulgaria?

• When you may become a Bulgarian tax resident.
• Whether your previous country requires departure formalities.
• Which identification and registration documents you need.
• Where your health and social insurance obligations arise.
• Which foreign income may need to be declared.
• Which records you should collect for your first tax return.

These checks can make your relocation more predictable and reduce the risk of administrative difficulties. The right approach depends on your personal situation, income sources and international connections.

Takeaways

• Bulgarian tax residency depends on more than the 183-day rule.
• Moving does not automatically end previous tax obligations.
• Foreign income may have Bulgarian reporting implications.
• Tax residency and social insurance are separate matters.
• Early preparation helps prevent avoidable mistakes.
