Bulgaria charges 10% flat income tax — the lowest rate in the European Union. Not 10% on the first bracket. Not 10% after deductions phase out. Ten percent on everything, from the first euro to the last. For freelancers, the effective rate drops to 7.5%. For companies, 10% corporate plus 5% dividend equals just 10% + 5% combined. And since January 1, 2026, all of this is in euros.
This guide covers every step: who qualifies, how the 183-day rule actually works, what the centre of vital interests test involves, how to get the NRA tax residency certificate, which business structure saves you the most, and what changed in 2026 with Euro adoption. It is written by a Bulgarian law firm that has handled this process for over 50 clients.
What Is Bulgaria Tax Residency — and Why It Matters in 2026
Tax residency is the legal relationship between you and a country that determines where you owe taxes on your worldwide income. It is not the same as citizenship, nationality, or immigration status. You can be a German citizen, hold a Bulgarian residency card, and be tax resident in Bulgaria — paying 10% instead of 42%.
When you become a Bulgarian tax resident, two things happen:
- Bulgaria taxes your worldwide income at 10%. Employment, freelancing, dividends, capital gains, rental income — all at the flat rate.
- Your previous country should stop taxing you — provided you properly de-register and can invoke a double taxation treaty. Bulgaria has agreements with over 70 countries, including Germany, France, the UK, the Netherlands, Austria, and the United States.
Why does 2026 matter specifically? Three reasons. First, Bulgaria adopted the Euro on January 1, 2026 — eliminating currency risk and making the country a more credible base for EU-facing businesses. Second, the Digital Nomad Visa (launched December 2025) opens Bulgaria to non-EU remote workers for the first time. Third, updated transfer pricing rules and SAF-T reporting requirements demand proper structuring from the start.
Bulgaria Tax Residency Requirements
Bulgarian tax law (Article 4 of the IDDFL — Income Taxes on Individuals Act) defines four criteria. Meeting any one of them makes you a tax resident:
The 183-Day Rule
Spend more than 183 days in Bulgaria within any 12-month period, and you are tax resident for the calendar year in which you cross the threshold.
How the count works: Both the day you arrive and the day you depart count as days in Bulgaria. Days spent abroad for education or medical treatment do not interrupt your stay but may not count toward the 183 total. Keep boarding passes, apartment utility bills, and bank transaction records as evidence.
This is the most common and most straightforward path. The NRA (National Revenue Agency) recognizes it as the strongest basis for issuing a tax residency certificate. We recommend this route in your first year — it provides the cleanest case and the fewest questions from both Bulgarian and home-country tax authorities.
Centre of Vital Interests Test
You can qualify with fewer than 183 days if Bulgaria is your centre of vital interests — meaning your personal and economic ties to Bulgaria outweigh your ties to any other country.
The NRA evaluates:
- Family: Where does your spouse or partner live? Where do your children go to school?
- Permanent home: Do you own or rent property in Bulgaria? Is it your primary residence?
- Business: Is your company registered in Bulgaria? Do you earn income from Bulgarian sources?
- Financial accounts: Where is your primary bank account? Where do you receive income?
- Social ties: Where are you registered for healthcare? Where do you pay social security?
Warning: Centre of vital interests is subjective. If your home country also claims you are tax resident, the dispute is resolved by the tie-breaker rules in the applicable double taxation treaty — not by Bulgarian law alone. This is why we recommend 183+ days in year one as your foundation, then relying on centre of vital interests from year two onward.
Permanent Address in Bulgaria
Having a permanent address registered in Bulgaria can serve as an additional factor, though it alone is rarely sufficient. It supports the centre-of-vital-interests argument when combined with other evidence.
Sent Abroad by a Bulgarian Employer
Individuals sent abroad by a Bulgarian state institution or employer remain tax resident regardless of days spent in Bulgaria. This applies primarily to diplomats and government employees.
Bulgaria Tax Rates for Residents in 2026
Here is every rate you need to know, in one table:
| Tax type | Rate | Notes |
|---|---|---|
| Personal income tax | 10% | Flat rate on worldwide income |
| Corporate income tax | 10% | Flat rate, lowest in the EU |
| Dividend withholding tax | 5% | On after-tax profit distributed to individuals |
| Capital gains (general) | 10% | On sale of assets, crypto, shares |
| Capital gains (EU-regulated exchange) | 0% | Exempt if traded on EU-regulated market |
| Interest (EU/EEA bank accounts) | 0% | Exempt since April 2022 |
| Rental income | 10% | After 10% automatic expense deduction |
| VAT (standard) | 20% | Registration threshold: EUR 51,130 |
| Inheritance tax (close family) | 0% | Spouse, children, parents — exempt |
| Wealth tax | 0% | Does not exist in Bulgaria |
Compare that to the rates you may be leaving behind:
| Country | Top income tax | Corporate tax | Dividend tax |
|---|---|---|---|
| Bulgaria | 10% | 10% | 5% |
| Germany | 45% + solidarity | ~30% | 26.4% |
| France | 45% | 25% | 30% |
| Netherlands | 49.5% | 25.8% | 26.9% |
| United Kingdom | 45% | 25% | 39.35% |
| Sweden | ~52% | 20.6% | 30% |
| Spain | 47% | 25% | 28% |
How Much Tax Will You Actually Pay? Real Calculations
Rates in isolation don't tell the full story. Social security contributions matter. So does your business structure. Here is what you actually keep at different income levels:
Freelancer Effective Rate (~7.5% Income Tax)
Bulgarian freelancers (svobodna profesiya) receive an automatic 25% recognized expense deduction — no receipts required. You are taxed on 75% of gross revenue:
EUR 100,000 gross income example:
- Taxable base: EUR 75,000 (after 25% deduction)
- Income tax: EUR 7,500 (10% of EUR 75,000)
- Social contributions: ~EUR 8,400/year (capped at ceiling)
- Total tax + social: ~EUR 15,900
- Net income: ~EUR 84,100 (effective rate: ~15.9%)
In Germany, that same EUR 100,000 would leave you with approximately EUR 55,000-60,000 after income tax and social contributions. Bulgaria saves you ~EUR 24,000-29,000 per year on EUR 100K income.
EOOD Company Effective Rate (10% + 5%)
Running a Bulgarian EOOD (single-member limited company):
EUR 100,000 company revenue example:
- Corporate tax: EUR 10,000 (10%)
- After-tax profit: EUR 90,000
- Dividend tax: EUR 4,500 (5% of EUR 90,000)
- Manager salary social contributions: ~EUR 2,100/year (on minimum base)
- Total tax + social: ~EUR 16,600
- Net income: ~EUR 83,400 (effective rate: ~16.6%)
Freelancer vs Company: Which Is Better?
| Factor | Freelancer | EOOD Company |
|---|---|---|
| Effective income tax | 7.5% | 10% + 5% (combined) |
| Social contributions | Higher (on taxable income) | Lower (on manager salary) |
| Setup time | 1 day | 3 business days |
| Accounting complexity | Simple | Double-entry bookkeeping |
| Personal liability | Unlimited | Limited to capital |
| B2B perception | Individual | Company entity |
| Expense deductions | Flat 25% (automatic) | Actual business expenses |
| Best for income under | EUR 100K | EUR 100K+ |
| VAT threshold | EUR 51,130 | EUR 51,130 |
Our recommendation: Under EUR 100,000 annual income — start as a freelancer. Simpler, cheaper, and the effective rate is comparable or lower. Above EUR 100,000 — model both structures with your accountant. Above EUR 200,000 — consider a hybrid approach with both a company and freelancer activity.

Social Security Contributions in Bulgaria
Social security is where many guides lose clarity. Here is the 2026 breakdown:
| Contribution | Freelancer rate | Employee share | Employer share |
|---|---|---|---|
| Pension (State) | 19.8% | 10.58% | ~14.12% |
| Health insurance | 8% | 3.2% | 4.8% |
| Unemployment | — | 0.4% | 0.6% |
| Total | ~27.8% | ~13.78% | ~19.52% |
Critical detail: These percentages apply only up to the maximum insurance base of EUR 2,111.64/month (2026). Above that ceiling, you pay zero additional contributions. This cap is what makes Bulgaria's system so attractive for high earners — your social security payments are fixed regardless of whether you earn EUR 3,000 or EUR 30,000 per month.
The minimum insurance base for freelancers in 2026 is EUR 550.66/month. Even if you earn more, you can declare contributions on this minimum base (subject to your actual income declaration in the annual return).
How to Become a Tax Resident in Bulgaria: Step by Step
For EU Citizens
- Obtain your Bulgarian Residency Card. Apply at the Migration Directorate with your passport, rental agreement, health insurance proof, and financial proof. Fast-track processing: 3 business days. The card is valid for 5 years. We handle the full process.
- Register your address. Permanent address registration at the local municipality (obshtina). Required for tax registration and NRA filings.
- Register as a freelancer or incorporate an EOOD. Freelancer: 1 day at the NRA. EOOD: 3 business days via the Trade Registry. We prepare all documents and file on your behalf via Power of Attorney.
- Open a bank account. Bulgarian bank or EU-licensed fintech. We prepare the full KYC package and accompany you to the bank. Account active within 1 day of approval.
- Register with the NRA for tax and social security. Obtain your tax identification, set up social security declarations, and register for VAT if applicable (threshold: EUR 51,130).
- Establish your presence. Spend 183+ days in Bulgaria during your first calendar year. Maintain records: utility bills, bank statements, travel history.
- Apply for the Tax Residency Certificate. After establishing sufficient presence, submit your application to the NRA. Processing: 7-30 days. Details below.
- De-register from your home country. Notify your home-country tax authority. Requirements vary — Germany requires an Abmeldung, France has exit tax provisions, the UK applies the Statutory Residence Test. We coordinate with home-country advisors.
For Non-EU Citizens
Non-EU nationals follow the same tax residency path but need a valid residence permit first. Options include:
- Visa D + Long-Term Residence Permit: For company owners, employees of Bulgarian companies, or family reunification.
- Digital Nomad Visa (new since December 2025): For remote workers earning from foreign sources. 1-year permit, renewable once. Income requirement: approximately EUR 31,000/year (50x minimum monthly wage). The visa alone does not make you tax resident, but spending 183+ days in Bulgaria does.
- Trade Representative Office Registration: A pathway for entrepreneurs establishing business presence.
How to Get a Tax Residency Certificate from the NRA
The Tax Residency Certificate (Udostoverenie za lokalno litze) is the official document issued by the NRA that proves your Bulgarian tax residency. You need it to claim double taxation treaty benefits and to prove your status to foreign tax authorities, banks, and institutions.
Required Documents
- Official application form (NRA template — "Application for Issuance of a Certificate of a Resident Person")
- Copy of your Bulgarian residency card
- Rental agreement or property deed
- Travel records (passport stamps, boarding passes, airline/railway records)
- Utility bills in your name (proving physical presence)
- Bank statements from Bulgarian accounts
- Employment or freelance registration documents
- Social security contribution records
- Power of Attorney (if represented by a lawyer)
Timeline and Costs
Processing time: 7 to 30 days, depending on the NRA office and complexity of your case. Government fee: approximately EUR 50. The certificate is valid for one calendar year and must be renewed annually.
Timing tip: Apply for the certificate in the second half of the year — after you have accumulated enough days and evidence. The NRA will assess your status for the entire calendar year, so applying too early can result in delays or requests for additional documentation.
Double Taxation Treaties
Bulgaria has signed double taxation agreements with over 70 countries. These treaties serve two purposes:
- Prevent double taxation: Ensure you are not taxed on the same income by both Bulgaria and your home country.
- Provide tie-breaker rules: If both countries claim you as a tax resident, the treaty determines which country's claim takes priority — typically based on permanent home, then centre of vital interests, then habitual abode, then nationality.
Key treaty partners include: Germany, France, Netherlands, United Kingdom, Austria, Switzerland, United States, Canada, Italy, Spain, Belgium, Sweden, Denmark, Finland, Greece, Czech Republic, Poland, Romania, UAE, China, Japan, and Singapore.
Important: Where no treaty exists, Bulgaria offers a unilateral foreign tax credit — you can deduct foreign taxes paid from your Bulgarian tax liability, on a per-country basis. This prevents double taxation even without a treaty, though less efficiently.
What Changed in 2026: Euro Adoption and New Rules
Bulgaria's accession to the Eurozone on January 1, 2026 is the single biggest change. Here is what it means for tax residents:
- All amounts are now in euros. Tax filings, invoices, accounting, NRA payments — everything converted at the fixed rate of 1 EUR = 1.95583 BGN.
- Zero currency risk. If your clients pay in euros, your income and expenses are now in the same currency. No more conversion losses.
- Stronger international credibility. A Eurozone company is taken more seriously by banks, partners, and clients than one in a non-euro EU member state.
- Tax rates are unchanged. 10% flat personal and corporate tax remain. Euro adoption did not affect the tax code.
Other 2026 changes:
- Minimum wage: Increased to EUR 620.20/month (from EUR 550.66). This affects minimum social contribution bases.
- VAT registration threshold: Set at EUR 51,130 with a 7-day registration deadline after exceeding.
- Transfer pricing: OECD-aligned rules now in force — substance-over-form, DEMPE framework. Relevant for companies with related-party transactions.
- SAF-T reporting: Phased implementation beginning 2026 for large enterprises.
- Digital Nomad Visa: Applications opened December 20, 2025. Income requirement: ~EUR 31,000/year.
Key Deductions and Tax Reliefs
Bulgarian tax law provides several deductions that reduce your taxable base:
| Deduction | Amount | Who qualifies |
|---|---|---|
| Freelancer expense deduction | 25% of gross income | All freelancers (automatic) |
| Lawyer expense deduction | 40% of gross income | Registered lawyers |
| Royalty income deduction | 40% of gross income | Authors, artists |
| Agricultural income deduction | 60% of gross income | Registered agricultural producers |
| Rental income deduction | 10% of gross rental | Property owners |
| Child tax relief | EUR 3,068 per child | Tax residents with children |
| Charitable donations | Up to 65% of taxable base | All tax residents |
| Mortgage interest (young families) | Up to EUR 51,129 | First home, under 35 years |
| Voluntary pension contributions | Up to 10% of taxable base | All tax residents |
Tax Filing Deadlines and Compliance
Bulgarian tax year = calendar year. Key dates for 2026:
- April 30: Annual tax return filing deadline (personal income).
- March 31: File electronically by this date to receive a 5% discount on tax owed (capped at EUR 255.65). No outstanding liabilities allowed.
- Quarterly: Freelancers pay advance tax installments (April 15, July 15, October 15, December 15).
- Monthly: Social security declarations due by the 25th of the following month.
- September 30: Deadline for submitting corrective annual returns without penalty.
- June 30: Corporate annual tax return deadline (for EOOD/OOD companies).
Pro tip: Always file electronically before March 31. The 5% early-filing discount is free money, and electronic filing is faster and creates a clear audit trail. We file on behalf of our clients as part of our accounting service.
Common Mistakes to Avoid
After handling 50+ tax residency cases, these are the errors we see most often:
- Not de-registering from the home country. Getting your Bulgarian certificate is only half the work. If you remain registered in Germany, France, or the Netherlands, they will continue claiming you as tax resident. You must actively exit.
- Insufficient documentation of physical presence. The NRA may request proof of your 183 days. Keep boarding passes, utility bills, bank transaction records, and medical receipts. Tip: use a shared Google Sheet to log your travel dates.
- Choosing the wrong business structure. A company is not always better than freelancing. Model both scenarios before committing — the difference can be thousands of euros per year.
- Ignoring social security. Many newcomers focus only on income tax and forget that social contributions can add 5-10% to your effective rate. The cap works in your favor above EUR 25,000/year, but below that, contributions are a larger percentage.
- Missing VAT registration threshold. If your revenue exceeds EUR 51,130, you have 7 days to register for VAT. Missing this deadline results in penalties and retroactive VAT liability.
- Attempting the process without local legal counsel. Bulgarian institutions operate in Bulgarian. Forms are in Bulgarian. NRA correspondence is in Bulgarian. Without a local representative, simple administrative steps become time-consuming obstacles.
