Bulgaria is classified as an Emerging Innovator within the European Union and continues to rely on a combination of a low-cost operating environment, a simple and favourable tax system, and substantial EU structural funding to stimulate innovation and competitiveness. The country’s policy focus is on increasing historically low R&D investment levels and accelerating the adoption of digital and green technologies, primarily through targeted grant schemes rather than tax-based R&D incentives.
Bulgaria operates one of the most competitive basic tax regimes in the European Union. Corporate income tax is levied at a flat rate of 10% for most entities, complemented by a flat 10% personal income tax rate. While these measures are not innovation-specific, they significantly reduce the overall cost base for businesses and support reinvestment into growth and development activities, including R&D.
Unlike many EU member states, Bulgaria does not currently offer dedicated R&D tax credits, super-deductions or patent box regimes. The national policy approach favours direct financial support through grants and EU co-financed programmes rather than indirect tax incentives.
Companies investing in regions with high unemployment may benefit from regional investment incentives, including the possibility of retaining up to 100% of the corporate income tax due for a defined period. These incentives are designed to promote job creation and economic development outside major urban centres.
The Invest Bulgaria Agency acts as a central contact point for foreign investors, providing information, administrative support and guidance on eligibility for national and EU-backed incentive schemes. While the agency does not itself grant funding, it plays a key facilitative role in navigating Bulgaria’s incentive landscape.
Direct, non-reimbursable grants co-financed by the European Union represent the primary source of innovation and competitiveness funding in Bulgaria.
The Competitiveness and Innovation in Enterprises Programme (CIEP) is the main EU-backed operational programme supporting business innovation, with a total budget of approximately BGN 3 billion. The programme aims to deliver smart and sustainable growth by focusing on three main areas:
Funding intensity under CIEP is particularly favourable for smaller enterprises. Micro and small enterprises may receive grants covering up to 80% of eligible costs, while medium-sized enterprises may receive up to 75%.
Under Bulgaria’s National Recovery and Resilience Plan, the Economic Transformation Programme provides additional grants and financial instruments to support technological modernisation and productivity improvements. This includes a dedicated technology modernisation fund of approximately BGN 260 million, aimed at increasing production efficiency and reducing operating costs.
The National Innovation Fund is Bulgaria’s primary domestic instrument for co-financing research and development projects. It is administered by the Bulgarian Small and Medium Enterprises Promotion Agency and plays a complementary role to EU-funded schemes.
The fund provides grants of up to BGN 500,000 for R&D projects and up to BGN 50,000 for technical feasibility studies. Funding is targeted at industrial research and experimental development projects, with a strong emphasis on cooperation between businesses and research organisations.
Grant intensity depends on the project stage and the size of the beneficiary. Base aid levels are typically 50% for industrial research and 25% for experimental development, with uplifts of up to 10% for medium-sized enterprises and up to 20% for small enterprises. In certain cases, total aid intensity may reach up to 80% of eligible costs.
Projects supported by the National Innovation Fund are expected to align with Bulgaria’s Innovation Strategy for Smart Specialisation, covering priority areas such as mechatronics, information and communication technologies and life sciences.
Bulgaria’s innovation ecosystem benefits from a growing network of support organisations and an emerging venture capital market.
Institutions such as Sofia Tech Park provide infrastructure, laboratory facilities and support services that help bridge the gap between academia and industry, particularly for technology-oriented start-ups.
Bulgarian organisations are also encouraged to participate in international R&D cooperation programmes, including Eurostars and EUREKA. National authorities support involvement in these networks to facilitate access to international expertise, partnerships and additional sources of funding.
The domestic venture capital market remains relatively small compared to EU averages, but investment activity is gradually increasing. Bulgaria’s low operating costs and strong pool of IT and engineering talent continue to attract regional and international investors seeking early-stage opportunities.
Bulgaria’s innovation funding framework relies primarily on high-intensity, non-repayable grants financed through EU structural funds, complemented by a simple and competitive tax environment and targeted national support via the National Innovation Fund. Although the country does not offer dedicated R&D tax incentives, its flat 10% corporate tax rate and generous grant funding make it an attractive location for cost-efficient innovation, particularly for SMEs engaged in digital and green transformation.
Early planning and careful alignment with EU and national programme priorities are essential for businesses seeking to maximise available funding and ensure compliance with state aid and eligibility requirements.
