Bulgaria vs Romania: Tax Regime Comparison

Bulgaria and Romania are two of the European Union';s most tax-competitive jurisdictions, yet they differ substantially in structure, rates, and compliance burden. Bulgaria maintains a flat 10% corporate income tax rate - one of the lowest in the EU - while Romania operates a tiered system that favours micro-enterprises but imposes a standard 16% rate on larger companies. For international founders and business owners choosing between the two, the decision turns on entity size, revenue profile, dividend strategy, and long-term operational plans. This guide compares the two countries across corporate tax, personal income tax, VAT, dividend treatment, payroll obligations, and compliance costs, giving you a clear framework for tax planning decisions.

Bulgaria';s corporate income tax is governed by the Corporate Income Tax Act and is set at a flat 10% on taxable profit. There are no surtaxes, no municipal add-ons, and no progressive brackets. This simplicity makes Bulgaria one of the most straightforward corporate tax environments in the EU. The National Revenue Agency (NRA) is the competent authority for corporate tax administration, and annual returns are filed by the end of March following the tax year.

Romania applies a standard corporate income tax rate of 16% under the Fiscal Code. However, Romania';s tax system includes a significant alternative regime for micro-enterprises - companies with annual turnover below a defined threshold and meeting certain structural criteria. Under this regime, tax is levied on revenue rather than profit, at rates that vary depending on whether the company has employees. This revenue-based tax can be highly advantageous for early-stage or low-margin businesses, but it also means that companies cannot deduct expenses, which creates a structural difference from Bulgaria';s profit-based system.

In practice, founders should consider that Romania';s micro-enterprise regime is not automatically available. Eligibility depends on turnover ceilings, ownership structure, and the number of shareholders holding stakes in multiple companies. A common mistake among foreign founders is assuming that the micro-enterprise rate applies indefinitely - in reality, exceeding the revenue threshold triggers a switch to the standard 16% rate, sometimes mid-year, with retroactive implications.

Bulgaria';s flat rate applies uniformly regardless of company size or revenue. This predictability is a genuine advantage for tax planning, particularly for businesses with volatile revenue or those scaling rapidly. There are no hidden thresholds that change the tax treatment.

Bulgaria taxes personal income at a flat 10% rate under the Income Taxes on Natural Persons Act. This applies to employment income, self-employment income, and most other categories of personal earnings. Dividends paid to Bulgarian resident individuals are subject to a 5% withholding tax, and dividends paid to non-resident individuals or foreign entities are also generally taxed at 5%, subject to applicable double tax treaties. Bulgaria has an extensive treaty network covering most major business jurisdictions.

Romania taxes personal income at a flat 10% rate as well, making the headline rate identical to Bulgaria. However, Romania also levies social health insurance contributions on dividend income received by individuals - a charge that does not apply in Bulgaria. This means that the effective tax burden on dividends extracted by individual shareholders is higher in Romania than the headline rate suggests. The Romanian National Agency for Fiscal Administration (ANAF) administers these obligations.

Dividends paid by Romanian companies to non-resident entities are subject to a 8% withholding tax under the current Fiscal Code provisions, unless a lower treaty rate or the EU Parent-Subsidiary Directive applies. Bulgaria applies a 5% withholding tax on dividends to non-residents, again subject to treaty reductions. For holding structures and international investors, Bulgaria';s lower dividend withholding rate is a meaningful advantage.

A non-obvious requirement in Romania is that health contribution obligations on dividends are calculated on the total annual dividend income of the individual, not per distribution. This can create unexpected year-end liabilities for shareholders who receive multiple distributions or who have other income sources subject to the same contribution ceiling.

Bulgaria';s standard VAT rate is 20%, administered under the Value Added Tax Act. Registration is mandatory once taxable turnover exceeds a defined threshold over a rolling twelve-month period. Voluntary registration is available below the threshold and is commonly used by businesses that deal primarily with VAT-registered counterparties. The NRA processes VAT registrations, and the procedure typically takes one to two weeks for straightforward applications.

Romania';s standard VAT rate is also 19%, slightly below Bulgaria';s 20%. Romania has a lower mandatory registration threshold than Bulgaria, meaning that businesses in Romania are required to register for VAT earlier in their growth cycle. This has practical implications for cash flow management and administrative burden, particularly for small businesses that are not yet generating significant revenue.

Both countries apply reduced VAT rates to specific categories such as food, hospitality, and certain services. Romania has historically applied a broader range of reduced rates, which can benefit businesses in the hospitality or food service sectors. However, Romania';s VAT compliance environment is generally considered more complex, with more frequent changes to rates and categories in recent years.

In practice, founders should consider that VAT compliance in Romania involves more frequent filing obligations and a higher risk of audit scrutiny for newly registered entities. Bulgaria';s VAT administration is generally regarded as more stable and predictable. A common mistake is underestimating the administrative cost of VAT compliance in Romania, particularly for businesses without a dedicated accountant familiar with local requirements.

Employment costs represent a significant component of the total tax burden in both countries, and the differences here are material. In Bulgaria, the total social security and health insurance contribution rate is split between employer and employee. The employer';s share of contributions is relatively low by EU standards, making Bulgaria competitive for labour-intensive businesses. Contributions are calculated on gross salary up to an annual ceiling, above which no further contributions are due.

Romania';s social contribution structure is different in a significant way. Under recent reforms, the majority of social contributions in Romania are borne by the employee rather than the employer. The employer pays a smaller percentage, but the employee';s combined social and health contributions are substantial - typically exceeding 35% of gross salary. This structure means that the net-to-gross ratio for employees in Romania is less favourable than in Bulgaria, which affects recruitment and compensation negotiations.

For businesses hiring locally, Bulgaria';s lower total employment cost per unit of net salary is a practical advantage. For businesses where the employer';s cash outflow is the primary concern, Romania';s employer-side contribution structure may appear attractive at first glance, but the total cost of employment - including the salary level needed to attract qualified staff at a given net pay - tends to be comparable or higher.

A common mistake among foreign employers in Romania is structuring compensation packages based on gross salary figures without accounting for the employee';s contribution burden. This can lead to misaligned expectations and higher-than-anticipated total payroll costs when employees negotiate on a net basis.

The compliance burden in both countries is relevant to the total cost of operating a legal entity. In Bulgaria, corporate tax returns are filed annually by the end of March. Monthly or quarterly advance payments are required for companies above a certain profit threshold. VAT returns are filed monthly for most registered businesses. The NRA operates an electronic filing system, and most filings can be completed remotely with a qualified accountant.

Romania';s compliance calendar is more demanding. Corporate taxpayers file quarterly advance payments and an annual reconciliation return. Micro-enterprises file quarterly revenue-based tax returns. VAT returns are filed monthly or quarterly depending on turnover. In addition, Romania requires more frequent interaction with ANAF for various declarations, including payroll-related filings that must be submitted monthly.

The cost of professional accounting and tax compliance services reflects this difference. In Bulgaria, monthly accounting fees for a small to medium company typically start from the low hundreds of EUR per month, depending on transaction volume. In Romania, fees tend to be somewhat higher for equivalent service levels, reflecting the greater complexity of the compliance environment.

Both countries have implemented electronic invoicing requirements in recent years, with Romania having moved more aggressively toward mandatory e-invoicing for B2B transactions. This imposes an additional technology and process requirement on businesses operating in Romania, particularly those that are not already using compliant accounting software.

Many underestimate the cumulative administrative cost of operating in Romania compared to Bulgaria. The difference is not dramatic for a single entity, but for a group with multiple subsidiaries or high transaction volumes, the compliance overhead in Romania can be meaningfully higher.

Scenario one: a technology services company with international clients. A founder establishing a software development company to serve EU and US clients is considering both jurisdictions. The company will have five to ten employees, moderate payroll costs, and high profit margins. In Bulgaria, the 10% corporate tax rate and 5% dividend withholding create a low combined tax burden on extracted profits. Employment costs are competitive. VAT compliance is straightforward. Bulgaria is the stronger choice for this profile.

Scenario two: a small e-commerce or retail business with modest turnover. A founder launching an online retail operation expects turnover below Romania';s micro-enterprise threshold in the first two to three years. Under Romania';s micro-enterprise regime, tax is levied on revenue at a low rate, which can result in a very low effective tax burden if margins are thin. If the business remains below the threshold, Romania may offer a lower tax cost in the early years. However, once the business scales beyond the threshold, the 16% standard rate applies, and the advantage disappears.

Scenario three: a holding company or investment vehicle. An international investor seeking to establish a holding structure to receive dividends from EU subsidiaries will generally find Bulgaria more efficient. The 5% dividend withholding rate, the EU Parent-Subsidiary Directive exemptions, and Bulgaria';s treaty network make it a cost-effective holding location. Romania';s higher withholding rate and health contribution obligations on dividends make it less attractive for pure holding purposes.

These scenarios illustrate that the optimal jurisdiction depends heavily on business model, scale, and extraction strategy. There is no single answer that applies to all situations.

What is the effective combined tax burden on profits extracted as dividends in each country?

In Bulgaria, a company paying 10% corporate tax and then distributing the after-tax profit as dividends to an individual shareholder incurs a further 5% withholding tax. The combined effective rate on pre-tax profit is approximately 14.5%, calculated as 10% corporate tax plus 5% applied to the remaining 90%. In Romania, the standard corporate tax is 16%, and dividends to individuals attract an 8% withholding tax plus potential health contribution obligations. The combined burden is higher than in Bulgaria in most scenarios. For non-resident corporate shareholders, treaty rates may reduce withholding in both countries, but Bulgaria';s lower base rates generally result in a more favourable outcome. The exact effective rate depends on the shareholder';s residency, applicable treaty, and whether EU directive exemptions apply.

How long does it take to register a company and obtain tax registration in each country?

In Bulgaria, a limited liability company (OOD) can typically be incorporated and registered with the Commercial Register within five to seven business days if documents are in order. Tax registration with the NRA follows automatically upon commercial registration. VAT registration takes an additional one to two weeks. In Romania, company formation through the Trade Register Office typically takes a similar period, but the process involves more documentation requirements and can take longer if there are queries from the registrar. Tax registration and VAT registration in Romania are separate steps and can add further time. In both countries, using a local lawyer or formation agent significantly reduces delays and the risk of rejection.

Is it possible to operate in both countries simultaneously, and how should a group structure be organised?

Yes, many international businesses operate entities in both Bulgaria and Romania, either to serve different markets or to optimise the group';s tax position. A common structure involves a Bulgarian holding or IP company receiving royalties or dividends from an operating subsidiary in Romania. This structure can be efficient if properly documented and commercially justified, but it requires careful attention to transfer pricing rules, substance requirements, and the anti-avoidance provisions in both countries'; tax codes. Both Bulgaria and Romania have implemented the EU Anti-Tax Avoidance Directives, which impose minimum substance and anti-abuse standards. A structure that lacks genuine economic substance in Bulgaria will not withstand scrutiny from Romanian or EU tax authorities.

Bulgaria and Romania both offer competitive tax environments within the EU, but they suit different business profiles. Bulgaria';s flat 10% corporate rate, low dividend withholding, and simpler compliance framework make it the stronger choice for profitable companies, holding structures, and businesses prioritising administrative efficiency. Romania';s micro-enterprise regime can be advantageous for early-stage businesses with low margins, but the standard rate, higher compliance burden, and dividend contribution obligations reduce its appeal at scale.
