Investing in Bulgaria is attracting more and more French people, drawn by still affordable prices, a light tax system, and a reassuring European framework. Behind the marketing argument of the “flat tax at 10%,” there is actually a set of fairly technical rules, especially when one crosses French tax laws, the tax treaty, and the treatment of real estate capital gains.
This article deciphers for a French reader the Bulgarian flat tax, the application of double taxation treaties, and the specifics regarding capital gains, rental income, and local taxes when buying, renting, or reselling a property in Bulgaria.
Becoming or Not a Bulgarian Tax Resident: A Decisive Starting Point
Before even discussing rents, capital gains, or the tax treaty, everything revolves around one question: Are you a Bulgarian tax resident or not? The answer completely changes your exposure to tax in Bulgaria… and in France.
In Bulgaria, tax residency status is based on three objective criteria: presence of more than 183 days in a twelve-month period, a permanent address, or the center of vital interests (family, home, economic activity). If none are met, the person is a non-resident and is only taxable on their Bulgarian-source income.
For a French person who keeps their family life, activity, and primary residence in France, while owning an apartment in Sofia or a house on the coast, the typical situation is to remain a French tax resident and simply be a non-resident in Bulgaria. In this case, only income derived from the Bulgarian property (rent, capital gains, certain interest) falls within the scope of Bulgarian tax.
A French person settles permanently in Bulgaria, stays there more than 183 days per year, and centers their economic and personal interests there. They become a Bulgarian tax resident, taxable on their worldwide income in Bulgaria, while France applies its non-resident rules and the tax treaty.
This distinction is fundamental: everything that follows (rental income, capital gains regime, possible exemptions, or application of treaties) varies depending on whether you are a Bulgarian tax resident or not.
The Bulgarian System: A 10% Flat Tax Without Brackets or Family Quotient
Bulgaria has opted for an ultra-simplified tax system, very different from that of France. The principle is that of proportional taxation, without progressive brackets.
The flat income tax rate applicable to most income in France is 10%.
The calculation method is linear: start with the gross income, deduct mandatory social security contributions and a few flat-rate charges (e.g., a statutory deduction of 10% for certain income), then apply the 10% rate. In practice, for a Bulgarian resident who receives rental income or realizes a capital gain, the tax is calculated exactly in this manner. For a non-resident, a tax at the 10% rate is generally withheld at source, without any real deductions, except under specific provisions.
The French are often surprised by the lightness of this system. Where a French landlord can see their rents taxed at a marginal rate of up to 45%, plus 17.2% in social security contributions, a landlord in Bulgaria, resident or non-resident, faces a principal tax of only 10% on their local income. It is this difference that makes Bulgaria a legal “little tax haven” within the European Union for income and capital gains, as long as residency rules and international treaties are respected.

Buying Real Estate in Bulgaria: Transfer, Local Fees, and VAT
On a strictly real estate level, Bulgaria operates with a two-tier tax system: the state handles income tax, capital gains, and VAT, while municipalities set property and transfer taxes.
When purchasing, the buyer is generally liable for a transfer tax due to the municipality where the property is located. Its rate varies between 0.1% and 3% depending on the municipality. In practice, large cities tend to be at the higher end of the range, with levels around 2% to 3% of the cadastral value or the declared value, the tax being calculated on the higher of the two.
In Bulgaria, the buyer pays a transfer tax, notary fees (0.1% to 1.5%), registration fees (around 0.1%), and possible agency fees. These costs amount to a few percent of the price, but apply equally to foreign and Bulgarian buyers.
VAT plays a special role in Bulgarian real estate. The sale of most older buildings is generally exempt from VAT, unless a specific option is exercised. However, the sale of buildings considered “new” remains subject to VAT at the standard rate of 20%, which can significantly increase the total cost for an investor. Land transactions, depending on their nature, may also be subject to VAT when carried out by a taxable person. For purchases from one individual to another, VAT is not the central point, but for transactions with developers or through companies, it can become a major issue, especially if the investor exceeds certain thresholds and falls within the scope of VAT in Bulgaria.

There is no wealth tax for individuals or companies in Bulgaria, unlike the French IFI (Impôt sur la Fortune Immobilière).
Holding real estate, even substantial, is not subject to an annual capital tax. Only local property taxes apply.
Property Tax and Recurring Charges: Generally Moderate Burden
Once the property is acquired, the French owner becomes subject to Bulgarian property tax. This is an annual local tax, based on the tax value of the property (cadastral value or value set by the municipality). Municipalities have wide latitude: the property tax rate can range from about 0.01% to 0.45% of the reference value.
For residential properties, large Bulgarian municipalities typically set the rate between 0.15% and 0.30%, while rural areas or small towns sometimes apply even lower rates. Overall, Bulgarian property tax remains significantly lower than in France, where property taxes can reach 1.5% to 3% of an increased rental base.
Added to this tax is a municipal waste collection fee. Its calculation depends heavily on the municipality: some set it as a percentage of the tax value, others based on trash volumes or collection contracts. In large cities, this fee remains a non-negligible item but incomparable to French mandatory levies on property ownership.
Furthermore, in condominium buildings or serviced residences, maintenance charges are added. These are not strictly tax-related, but they impact the investment’s profitability, whether for seaside resorts, ski complexes, or modern urban buildings.
The annual bill (property tax + waste fee) remains moderate in most cases, even for a foreign investor, especially compared to what they would pay in France for a property of similar value.
Taxation of Rental Income: A Simple and Rather Gentle Regime for the French
Regarding rentals, Bulgaria applies a scheme consistent with its flat tax philosophy. Rents received by an individual owner are taxable at the 10% rate, both for residents and non-residents, but with nuances in calculation method and the possibility of deductions.
For a Bulgarian resident who rents out an apartment or house, gross rents constitute taxable income. The law provides for a flat-rate deduction of 10% representing presumed expenses (routine maintenance, minor repairs, miscellaneous costs). Taxable income is therefore 90% of gross rent, and this amount is taxed at 10%. In reality, the direct tax burden on gross rent thus amounts to 9%, before taking into account possible social contributions or other specific taxes. The tax is paid in quarterly installments for the first three quarters of the year, then adjusted with the annual return.
For a French person who is not a Bulgarian tax resident, rents from a Bulgarian property are subject to a withholding tax of 10% on the gross amount, without the 10% flat-rate deduction. If the tenant is a company, it withholds and remits this amount. If it’s an individual, the principle remains a final tax of 10% of gross rent in Bulgaria.
The essential question for the French person is then: what about France? The tax treaty concluded between France and Bulgaria follows, for real estate income, the classic logic of treaties based on the OECD model. The right to tax income from a property is primarily allocated to the country where the property is located. In other words, for a rental in Bulgaria, Bulgaria has the power to tax the rents according to its own law.
French tax residents must declare their Bulgarian income, but the tax treaty avoids double taxation: a tax credit equal to the Bulgarian tax levied is granted in France, avoiding actual double taxation, although this income may influence the average rate applied to other French income.
In practice, the Bulgarian flat tax at 10% on rents therefore remains a competitive advantage for a French landlord, especially since the French tax pressure on rental income can be very heavy (progressive scale and social security contributions). The French investor must, however, anticipate the reporting obligations in France, including using the appropriate forms to declare foreign-source income and benefit from the application of the tax treaty.
Simplified Numerical Example
Let’s take an apartment rented for €12,000 per year in Bulgaria by a French person who is non-resident in Bulgaria but a French tax resident. In Bulgaria, a 10% withholding applies on the gross rent, i.e., €1,200 in tax. In France, this €12,000 must be declared as foreign rental income. The treaty allows offsetting the Bulgarian tax against the corresponding French tax or neutralizing double taxation via a tax credit. The net gain will depend on the French taxpayer’s marginal bracket, the structure of their other income, and the precise mechanics of the tax credit. But in most cases, the overall burden remains significantly lower than that of an equivalent investment in France taxed at full rate.
Real Estate Capital Gains: The Bulgarian 10%, Exemptions, and Coordination with France
The treatment of capital gains is at the heart of many investment strategies in Bulgaria. The basic rule is simple: the capital gain on the sale of real estate located in Bulgaria is taxed at 10%. But behind this simplicity lie several subtleties, particularly regarding the calculation of the gain, long-term exemptions, the position of non-residents, and the application of the Franco-Bulgarian treaty.
For a Bulgarian resident, the capital gain realized upon the disposal of a property is determined by taking the positive difference between the documented sale price and acquisition price, then applying a flat-rate deduction of 10% for presumed expenses. This net base is taxed at the rate of 10% as part of the annual return. Properly justified acquisition or sale expenses (notary fees, agency commissions, significant renovation work) also serve to reduce the taxable gain.
A Bulgarian resident or resident of an EU/EEA member state can sell their primary residence held for more than 3 years without taxing the capital gain. They can also sell up to 2 other properties held for more than 5 years with full exemption. Properties received as inheritance are also exempt from capital gains upon resale, regardless of the holding period.
For a non-resident, for example a French person who is not a Bulgarian tax resident, the logic is slightly different. Bulgaria considers the Bulgarian-source capital gain and applies a final tax of 10% on the realized gain. Again, the base corresponds to the sale price minus the acquisition price, with application of a statutory deduction of 10% for expenses, and the possibility of taking into account certain documented costs. The tax has the nature of a final withholding tax: the non-resident seller pays this levy in Bulgaria, which concludes, from the Bulgarian point of view, any further obligation regarding this capital gain.
Bulgaria taxes real estate capital gains at 10% via its flat tax because the property is located there. France, as the seller’s state of residence, can also tax this gain but must avoid double taxation through a tax credit or exemption. The French investor must declare the capital gain in France and benefits from a tax credit equal to the Bulgarian tax, up to the amount of French tax due.
This mechanism helps secure the investment: the Bulgarian tax at 10% is indeed taken into account by the French tax authorities, avoiding punitive cumulation of taxation. However, the exact level of tax savings will depend on the individual situation, the amount of the capital gain, the holding period, and the French regime applicable to foreign real estate capital gains. The practical challenge for a savvy investor is to intelligently combine long-term Bulgarian exemptions (3 years for a primary residence, 5 years for two other properties, inherited properties exempt) and the use of the French tax credit.
Capital Gain Calculation: A Concrete Scenario
To better understand, imagine the sale of an apartment purchased for €80,000 and resold for €120,000 by a French non-resident in Bulgaria. The gross gain is €40,000. Bulgarian law allows a flat-rate deduction of 10% on this gain, i.e., €4,000, bringing the taxable base to €36,000. The 10% tax amounts to €3,600. If significant documented expenses exist (structural works, major renovations, commissions), they can reduce the base even further.
In France, the capital gain on a property located abroad is declared according to French rules, with possible allowances. The tax treaty with Bulgaria allows a tax credit of €3,600 to neutralize double taxation, avoiding paying tax twice.
Comparison Bulgaria / France: A Considerable Gap in Tax Pressure
To measure the interest of a Bulgarian real estate project, it is useful to compare a few major parameters of the French and Bulgarian systems. Without detailing all the French rules, the contrast is clear on several key points: income tax, corporate tax, VAT, and social charges.
In Bulgaria, the income tax rate is flat, applying to all income levels.
Regarding corporate tax, Bulgaria applies a flat rate of 10% on profits, while France has stabilized its rate at around 25%. Again, the difference is significant for an investor who chooses to hold their operation in a Bulgarian company. Dividends distributed to individuals are subject in Bulgaria to a 5% only withholding, whereas in France dividends are generally subject to a flat tax of 30% (12.8% tax + 17.2% social contributions), unless opting for the progressive scale.
The level of mandatory social contributions in France is around 47% of gross salary for a typical employee, compared to about 33% in Bulgaria.
On VAT, both countries share a standard rate of 20%, although Bulgaria provides for a reduced rate of 9% for certain services (hotel accommodation, books, baby products). So it is not VAT that creates the Bulgarian advantage, but rather the combination of a flat tax on income, a reduced corporate tax, low capital levies, and a specific real estate tax regime on rents and capital gains.
Central Role of the Tax Treaty for the French
Any cross-border real estate strategy relies on a good understanding of the tax treaty linking the two states. Between France and Bulgaria, the text follows the usual logic of modern treaties: it allocates taxing rights, avoids double taxation, and contains anti-abuse clauses to limit purely tax-driven structures.
For real estate income, the treaty confirms that Bulgaria has priority to tax rents from a property located on its territory, as well as capital gains from the sale of that property. France, as the taxpayer’s state of residence, takes these revenues and gains into account, but must, according to the relevant articles, neutralize double taxation through a tax credit or exemption with inclusion in the effective rate.
In practice, a French tax resident receiving Bulgarian rents or realizing a capital gain in Bulgaria will:
– pay the corresponding tax in Bulgaria, at the rate of 10% (or less if exemptions apply) ;
– declare this income in France, using the forms provided for foreign income ;
– benefit from a French tax credit equal to the tax paid in Bulgaria (or up to the French tax on that same income), which avoids full cumulation of taxation.
It is important to emphasize that the tax credit is generally not a refund of the Bulgarian tax, but an offset that reduces French tax. The concrete result therefore depends on the ability of the tax credit to cover all or part of the additional French taxation.
Bulgaria offers a 10% tax rate on rents, possible full exemptions on certain long-term capital gains, and light local taxation on ownership. For a French person subject to the higher tax brackets, this allows significant optimization of the overall tax burden, even after applying the tax credit.
Comparative Summary Table
To better visualize the gap between the two countries on a few key items, here is a summary table, from the perspective of an individual investor.
| Item | Bulgaria | France |
|---|---|---|
| Income Tax (individuals) | Flat rate 10% | Progressive scale 11% to 45% |
| Corporate Tax | 10% | Approx. 25% |
| Tax on Rents (individual) | 10% on gross (non-resident), approx. 9% effective for resident after flat deduction | Progressive scale + 17.2% social contributions |
| Tax on Real Estate Capital Gains (Bulgaria) | 10%, with 10% statutory deduction and conditions for exemptions | Taxation in France under French real estate capital gains regime if applicable |
| Property Tax | 0.01% to 0.45% of tax value | 1.5% to 3% of rental value (order of magnitude) |
| VAT (standard rate) | 20% | 20% |
| Wealth Tax | None | IFI for certain real estate assets |
This table illustrates that, for a French person, Bulgaria is fiscally attractive at every level of the chain: purchase, ownership, income, disposal. The key is to properly manage the coordination with French taxation via the treaty so as not to lose the benefit of this advantage.
A Few Practical Points of Attention for a French Investor
Even if the Bulgarian tax environment is appealing, several elements warrant particular vigilance during a real estate project.
A French person who unintentionally transitions from non-resident to Bulgarian resident becomes taxable in Bulgaria on their worldwide income, requiring a complete overhaul of their wealth strategy.
Next, documentation of costs and acquisition prices is essential for capital gain calculations. Bulgaria requires, to determine the acquisition price, solid supporting documents: notarial deeds, invoices for work, agency contracts. Lack of these documents can lead to less favorable reconstruction methods and heavier taxation on the capital gain.
Non-residents do not benefit from the same flat-rate deductions as residents and are subject to a gross 10% levy on rents. In return, the withholding tax simplifies procedures by finalizing the tax declaration.
Finally, it is important to monitor turnover thresholds that may trigger a VAT registration obligation, particularly for an investor who engages in development or repeated resale operations. Beyond a certain volume (measured in Bulgarian lev then converted to euros), the investor moves into a more complex tax universe, with VAT returns, deduction rights on certain costs, but also enhanced invoicing and accounting obligations.
Conclusion: An Attractive Tax Framework, to Be Handled Methodically
Bulgarian real estate taxation, seen from France, combines several major assets: a flat tax at 10% on most income, favorable treatment of real estate capital gains with long-term exemptions, moderate property tax, and a complete absence of wealth tax. Added to this is a very low corporate tax and a withholding of only 5% on dividends paid to individuals.
The Franco-Bulgarian tax treaty avoids double taxation on Bulgarian rents and capital gains. The tax paid in Bulgaria is taken into account, but Bulgarian income can increase the effective tax rate in France.
A real estate project in Bulgaria thus becomes a possible tool for wealth optimization for a French person, provided it is carefully structured: choice of ownership method (direct or through a company), anticipation of tax residency, good understanding of long-term exemptions on capital gains, and mastery of reporting obligations on both sides of Europe. With these precautions, the promise of the 10% flat tax, the tax treaty, and a lenient capital gains tax regime can translate into a very concrete advantage for the French investor.
