Overview
Greece has expanded its innovation support framework in recent years, with the main levers now sitting across R&D tax relief, patent-related incentives, EU-backed funding and the updated development law adopted in 2025 . For businesses carrying out qualifying R&D, commercialising patented technology or planning investment in digital and industrial capability, Greece now offers a broader and more usable incentive mix than it did a few years ago.
The position is still best understood as a combination of tax relief and funding rather than a single flagship regime. In practice, companies will usually need to assess the interaction between tax measures, state aid limits, eligibility conditions and programme-specific application requirements before assuming support is available.
R&D tax relief
Greece allows an enhanced deduction for qualifying scientific and technological research expenditure, including depreciation on equipment and instruments used for R&D. Under the baseline rule, eligible expenditure is deductible at 200% overall, meaning the company receives the ordinary deduction plus an additional 100% uplift.
Law 5162/2024 widened the incentive from fiscal year 2025. The updated rules provide higher deduction rates in specific circumstances, including R&D carried out in collaboration with eligible startups, universities and recognised research bodies, and additional enhancements for certain SMEs.
This is an area where precision matters. Market commentary does not always describe the enhanced rates consistently, so any client-facing advice should be tied back to the legislation and current tax guidance before quoting a specific percentage for a particular fact pattern.
Patent incentives
Greece also provides a tax incentive for profits derived from the exploitation of internationally recognised patents developed by the company itself. The relief is linked to the company’s own R&D expenditure and is calculated by reference to qualifying and total R&D costs, rather than operating as a broad exemption for all patent income.
From fiscal year 2025, qualifying patent profits may benefit from an income tax exemption for up to three consecutive years. For the following seven years, a 10% exemption applies to the income tax payable on profits from exploitation of the patent.
Although this is sometimes described in commercial summaries as a patent box-style measure, that label should be used carefully. The Greek rules are more specific and should be described by reference to the statutory patent incentive rather than by analogy alone.
Funding and state aid
The Greece 2.0 Recovery and Resilience Plan remains a major source of support for investment, digital transition and innovation-led projects, with implementation running through August 2026. Alongside grant funding, the framework has also supported access to loan finance for eligible investment activity under favourable terms.
Separately, the development law adopted in 2025 updated the investment aid framework and introduced 12 aid schemes aimed at supporting areas such as modern technologies, innovation, manufacturing, green transition and regional development. Depending on the scheme and the location of the investment, support may be available through tax exemptions, grants, leasing subsidies or related financing support.
For clients, the practical point is that Greece can be attractive where a project has a clear capital investment profile and can be aligned with national or EU policy priorities. The limiting factors are usually procedural rather than conceptual: timing, approvals, evidence requirements and state aid rules tend to determine whether support is actually accessible.
Start-ups and investor measures
Elevate Greece, the national startup registry, remains a central part of the country’s innovation ecosystem and is relevant to access under several support measures. For non-EU investors, a residence permit route has been available from 1 January 2025 for investment of at least €250,000 in a startup registered with Elevate Greece, subject to statutory conditions including job creation requirements.
Law 5162/2024 also strengthened the angel investor regime. Current summaries indicate that the cap for the 50% income tax deduction was increased to €900,000, allocated across up to three startups or venture capital vehicles, which materially improves the position for higher-value early-stage investment.
Practical view
Greece now has a credible mix of innovation incentives, but the strongest points are narrower than some promotional summaries suggest. The R&D deduction is useful, the patent incentive is more developed than before, and the funding environment is stronger where projects fit the priorities of the development law or Greece 2.0.
For client-facing drafting, the safest tone is measured rather than promotional. It is reasonable to say that Greece offers a more competitive innovation incentives framework than in previous years, but claims such as “one of the most generous in the EU” or headline deduction rates without conditions should be avoided unless they are backed by current primary-source analysis for the exact scenario in question.
