Introduction
Foreign tax authorities, banks, pension funds, and counterparties often require formal proof of where a person or company is tax resident. This is usually the point where confusion begins.
You can be a Bulgarian tax resident without having proof of tax residence. Tax residence exists based on facts and circumstances; proof requires an official document issued by the tax authorities.
In Bulgaria, that proof is the Certificate of Tax Residence (Удостоверение за местно лице), issued by the National Revenue Agency (NRA). This article explains what the certificate is, when it is required, and how to obtain it in practice—clearly, calmly, and without legal jargon.
If you are unsure whether you qualify as a Bulgarian tax resident in the first place, see our detailed guide:

Quick Answer
A Certificate of Tax Residence in Bulgaria is an official document issued by the Bulgarian National Revenue Agency confirming that a person or company is considered tax resident in Bulgaria for one calendar year and one foreign country. It is mainly used to apply double tax treaties and must be requested separately for each year and each country.
What Is a Certificate of Tax Residence?
The certificate confirms that a person or entity qualifies as a “local person” (местно лице) under Bulgarian tax law.
In practical terms, it confirms:
- Tax residence in Bulgaria
- For a specific calendar year
- Usually for a specific foreign country, in the context of a double tax treaty
The certificate is not permanent and not general-purpose. It is issued on request, typically when a foreign authority asks for proof before applying treaty rules.
Who Can Apply
The following may apply for a Bulgarian Certificate of Tax Residence:
Individuals
- Foreign nationals living in Bulgaria
- Expats, investors, freelancers, consultants
- Company directors and shareholders
Companies
- Bulgarian legal entities
- Foreign-owned Bulgarian companies
Condition:
Applicants must meet Bulgarian tax residence criteria (e.g. presence exceeding 183 days or centre of vital interests in Bulgaria).
Holding a Bulgarian residence permit does not automatically make you a tax resident, nor does it replace a Certificate of Tax Residence. Residence permits are immigration documents, while tax residence is determined under tax law based on factual criteria such as presence and centre of vital interests.

Scope of Each Certificate
- Issued for current or past tax years
- Valid for one calendar year only
- Issued per foreign country
- Separate requests are required for multiple countries
How to Apply (Practical Steps)
1. Application Form
Applications are submitted using NRA Form ОКд-273 (request for issuance of a certificate of tax residence).
Physical persons and sole traders must complete Part II, which contains residency-related information.
The current form and official service description are available on the NRA website.
2. Where to File
The application is filed with the competent NRA office, determined by:
- Permanent address (individuals), or
- Registered seat and address of management (companies), as competence may depend on the specific NRA regional department, not only the city of registration.
3. Submission Methods
The request can be submitted:
- In person
- Via a licensed postal operator
- Electronically using:
- Qualified Electronic Signature (KEP), or
- Personal Identification Code (PIK)
4. Processing Time
The statutory deadlines are:
- 7 days – competent office
- 14 days – other NRA office
These deadlines apply only if no additional documents are requested. In practice, where tax residence needs clarification, processing may take several weeks.
There are no state fees.
5. Receiving the Certificate
Certificates can be received:
- In person
- By authorised proxy
- By post (including delivery abroad)
- Electronically, where applicable
Foreign Tax Authority Forms & Translations
Some countries require their own tax residence forms to be certified by the NRA.
In practice:
- Foreign forms usually require a certified Bulgarian translation
- Requirements vary by country
- German tax residence forms are commonly processed by the NRA
- Apostille or legalisation may be required in certain cases
Incorrect or incomplete foreign forms are a frequent cause of delays or refusals. If a foreign authority requires a specific form, verification in advance is strongly recommended.
Common Practical Pitfalls
The most common reasons applications fail or stall:
- Applying before Bulgarian tax residence is established
- Expecting one certificate to cover multiple countries
- Confusing a residence permit with tax residence
- Using the wrong tax year
- Assuming the certificate automatically eliminates foreign tax
- Failing to cut formal ties abroad (e.g. remaining registered for tax or social security in another country)
Tax residence is not only about where you live—it is about where your formal obligations are centred.
Relationship With Double Tax Treaties
The certificate supports treaty application, but it has clear limits.
What it does
- Confirms Bulgarian tax residence
- Enables foreign authorities to apply treaty rules
What it does not do
- It does not override foreign law
- It does not guarantee tax exemption
- It does not replace proper filings
It is evidence, not immunity.

Conclusion
The Bulgarian Certificate of Tax Residence is straightforward in theory, but in practice it often becomes a bottleneck—especially where foreign banks, dividend payments, or treaty relief are involved. Timing, correct scope (year and country), and proper substantiation of tax residence all matter, and small mistakes can lead to delays or refusals.
If you are applying for this certificate in the context of cross-border income or double tax treaty relief, it is usually worth ensuring the process is handled correctly the first time.

Frequently Asked Questions (FAQ)
Is a Certificate of Tax Residence the same as being tax resident in Bulgaria?
No. Tax residence is determined by facts (presence, centre of vital interests, etc.).
The certificate is a separate, official document issued by the NRA as proof of that status for foreign authorities.
How long is a Bulgarian Certificate of Tax Residence valid?
It is valid only for the calendar year stated on the certificate and usually only for the foreign country specified. A new certificate is required for each year and each country.
Can one certificate be used for multiple countries?
No. In practice, the NRA issues certificates per year and per country. If proof is required for more than one country, separate applications must be submitted.
Does the certificate automatically exempt me from foreign tax?
No. The certificate enables the application of a double tax treaty, but it does not grant automatic exemption or override foreign tax law. Additional conditions or filings may still apply abroad.
Can I apply for a Certificate of Tax Residence for a past year?
Yes, provided Bulgarian tax residence can be substantiated for that year.
Older years are usually reviewed more closely and may require additional supporting documentation.
What happens if the NRA requests additional documents?
You must provide the requested documents promptly. Common requests include proof of address, travel records, foreign tax deregistration, or social security documentation. Failure to comply may result in delays or refusal.
Is a residence permit sufficient proof of tax residence?
No. A residence permit is an immigration document. Foreign tax authorities generally require a Certificate of Tax Residence for treaty and withholding tax purposes.
