Forschungszulage: Fund & Bill External R&D Right
How to fund external service providers via the Forschungszulage: 70% cost basis since 2024, EU/EEA rules, billing requirements and 2026 changes.
Many AI teams invest heavily in personnel, data preparation, training, testing and product integration early on – often long before significant revenue flows in. This is exactly where the Forschungszulage comes in: it can reduce the financing burden without having to rely on classic, highly competitive grant programs with tight deadlines.
Important to understand: it is not about using "just any AI" – but about demonstrating real innovation that goes beyond the state of the art.
The Forschungszulage is a tax-based funding scheme for companies that implement innovative development projects (within the meaning of the Forschungszulagengesetz). For AI companies this often involves software, data and modelling projects – the decisive factor is not the industry, however, but whether your project meets the criteria (e.g. novelty, technical risk/uncertainty, systematic approach).
Particularly relevant for AI companies:
In principle, AI, IT and software projects are frequently eligible – if they qualify as innovative development work (e.g. experimental development).
Typical AI examples that often qualify:
Practical example: An AI startup developed a chatbot that processes emails and documents, automates filing and adapts to processes – the innovative development work was funded (with a focus on reliability/GDPR compliance, among other things). The feedback: high impact with comparatively low "bureaucracy feel" compared to other programmes.
For your project to be considered eligible, it must – in addition to being classified as development work – primarily meet these three criteria:
Your project must generate new knowledge/capabilities or use existing ones in a way that produces substantially better products/processes/services.
Important: it may not be sufficient to "merely" use an existing tool and train a model with it. The decisive factor is the technical innovation at the core of your project.
Reviewers want to see that there are genuine technical hurdles that could jeopardise success (not just commercial risks). Examples:
Practical note: follow-up questions are normal. In one approved case, for example, the technical risks and why they could not be resolved with existing technology were requested in more detail after submission – and then successfully answered.
Concrete examples of how a systematic approach is documented in development projects can be found here: Example projects.
You need a traceable project logic:
For many AI companies the Forschungszulage is so attractive because it:
Check project fit (innovation rather than buzzwords)
Describe and document the project clearly
Implement correctly and map the payout via tax
If you want to use the Forschungszulage strategically, one thing above all counts: the right argumentation of your innovation – so that it is traceable, verifiable and consistent.

If your AI project is more than "implementing standard tools" and involves genuine technical innovation with risks and a structured approach, the Forschungszulage is one of the strongest levers for financing development – especially for SMEs and startups.
Innovation means going beyond the state of the art – for example through new methods, measurably better results, technical breakthroughs in robustness/data protection/scaling, or a novel system architecture.
Often not. If the core is just "training with existing tools", the novelty criterion may be missing. A clear technical advancement is needed that you can justify and substantiate.
No. Especially SMEs and AI startups without profit can make attractive use of the Forschungszulage (the specific tax treatment depends on the individual case).
Yes, that is one of the great advantages – many companies use it to fund innovation that has already started.
Typically helpful: project plan, milestones, technical risk analysis, test and evaluation concepts, documentation, prototypes, benchmarks, technical decisions (Architecture Decision Records).
The most efficient approach is a structured initial review: novelty, risk/uncertainty, systematic approach – these are exactly the points where AI applications succeed or fail in practice.
