What is tax residency?

Tax residency determines the country in which an individual is considered a taxpayer and is therefore subject to taxation on some or all of their income. While the rules vary between jurisdictions, tax residency is typically established based on factors such as the amount of time spent in a country, the location of a person’s permanent home, family ties, or center of vital interests. Determining tax residency correctly is crucial for avoiding double taxation and ensuring compliance with local tax laws.

What do I need to do to become a tax resident of Bulgaria?

As most countries in the world Bulgaria has adopted national (domestic) laws which govern the matters of tax residency. They are usually quite broad and include: physical presence for a prolonged period of time; permanent address in Bulgaria; centre of vital interests.

If you want to move to Bulgaria and establish your “base” for tax purposes in the country you will need an address registration (a permanent address) and a residence permit. These are fairly easy to obtain and Tax monkey can of course help you with the respective procedures.

Can I be a tax resident of multiple countries?

In theory, it is possible to be considered a tax resident of more than one country at the same time under the domestic laws of those countries. This commonly occurs when an individual lives, works, or maintains significant personal and economic ties in multiple jurisdictions.

In such cases, double taxation treaties typically contain „tie-breaker“ rules that determine which country has the primary right to treat the individual as a tax resident for treaty purposes, helping to prevent double taxation and provide greater certainty regarding tax obligations.

What should I do to avoid being considered a tax resident of my home country instead of Bulgaria?

willing to spend the majority of your time around the year in Bulgaria, you will of course be good. We do however know that people love to travel around so here is what you should consider:

  • Obtain formal exit or deregistration (if available). You should deregister your address in any countries that might have a conflict regarding your tax residency;
  • Make sure to physically spend more time in the country than in other countries and document it;
  • Move tax and financial footprint. Use Bulgarian address for banking, brokers, insurance where possible.
  • Notify tax authorities of native country.

  • Limit your time spend in other jurisdictions.

  • Keep a paper trail.

How do I prove that I am a tax resident of Bulgaria to my home country tax authorities?

Proving tax residency typically requires demonstrating both factual presence in a country and formal recognition by the tax authorities. In practice, this is most commonly done through a tax residency certificate issued by the local tax authority (in Bulgaria, the National Revenue Agency). This certificate confirms that an individual is considered a tax resident for a specific tax year and is often used when applying double taxation treaties to avoid being taxed twice on the same income.

In addition to the tax residency certificate, individuals are often asked to provide supporting documentation such as certificates of filed tax returns and evidence of paid taxes. These documents help demonstrate that the individual is actively fulfilling their tax obligations in the country of residence. Together, these certificates form the key evidentiary basis used by foreign tax authorities, banks, and financial institutions to accept a person’s declared tax residency status.

Summary

Establishing and proving tax residency is an important step for anyone living, working, or earning income across different countries. While each jurisdiction applies its own criteria—typically based on time spent in the country, permanent home, and the center of vital interests—the outcome always depends on your overall personal and economic situation. Getting this right from the start can make a significant difference in avoiding future tax uncertainty or disputes.

Once tax residency is established, it is equally important to be able to clearly demonstrate it. This is usually done through official documents such as a tax residency certificate, together with filed tax returns and confirmations of paid taxes issued by the local tax authority. These documents are widely used by foreign tax authorities, banks, and business partners to recognize your tax status and apply double taxation treaty relief where applicable.

Because tax residency rules can be complex and highly fact-specific, many individuals benefit from professional guidance when structuring their move or cross-border activity. Proper planning not only ensures compliance, but also helps you make the most of the available tax framework in a clear and sustainable way.
