Why This Article Matters

The prototype phase determines whether an innovation is technically viable – and is simultaneously often the most expensive phase before first revenues. The Forschungszulage helps to cushion exactly these innovation costs from a tax perspective, if the prototype is part of a systematic, technically demanding development process and you document it in an audit-proof way.

Many companies leave money on the table because they position prototypes too close to pre-series/market activities or fail to keep evidence sufficiently distinct.


When Does Prototype Development Count as Eligible?

From a funding logic perspective, a prototype is not a "first sample" for sales or pitching, but a functional interim state that answers technical questions.

Prototype development is typically eligible when:

  • Innovation level is present (not just standard assembly or cosmetic optimization),
  • you proceed systematically (plan → implementation → test → iteration),
  • genuine technical uncertainties exist (e.g. function, integration, scaling, performance),
  • the prototype serves knowledge gain (e.g. through tests under realistic conditions).

Important: Whether physical (component, machine) or digital (software demonstrator, algorithm, AI model) is usually secondary – what matters is technical risk and traceable development.


What Is Typically Not Eligible (and Why)?

Funding becomes problematic where knowledge gain ends and market/operational logic begins.

Typically not eligible:

  • Design studies or models without technical function
  • Pre-series production and near-series implementation
  • Series development or pure product adaptation without new technical findings
  • Marketing/sales (even if it "belongs to the project")
  • classic project management (status updates, budget, deadlines), insofar as it is not actually technical development work

Key principle: "Included in the project" does not automatically mean "eligible for funding".


Which Costs Are Often Relevant for Prototypes?

Frequently relevant cost categories (cleanly delineated and documented):

Not the focus (and often not eligible): series production, production machinery, marketing.

If you are unsure whether a cost block is more "prototype/test" or already "pre-series/market": have it checked in advance – this avoids discussions later.


How to Set Up Your Prototype Project Correctly (Short & Audit-Proof)

1) Clear Delineation in the Project Plan

Make a visible distinction between:

  • Innovation work (development, tests, iterations)
  • non-eligible portions (pre-series, rollout, marketing, general coordination)

2) Name Technical Uncertainties Specifically

  • What is technically still unresolved?
  • Why is standard knowledge insufficient?
  • Which tests/experiments will provide the answers?

3) Documentation – Lean but Robust


Why the Forschungszulage Is So Attractive for Prototypes

The Forschungszulage is particularly well suited to prototype development because it:

  • works tax-based (no competitive process),
  • can be applied for retroactively,
  • enables flexible innovation planning independently of classic calls,
  • can map iterative cycles (build–test–improve) well – if the evidence is in order.

Why Working with zeitmaker.com Saves Time and Risk

With prototypes, it rarely fails on the technology – it fails on delineation, terminology, and documentation. zeitmaker.com helps you set up the project correctly from the start in terms of funding logic:

  • Free initial check of your project
  • Structuring of work packages and innovation argumentation
  • Support with documentation, evidence, and application texts

Conclusion: Prototype Development + Forschungszulage = Financially Securing Innovation

Prototypes are a central step toward market-ready innovation – and a major cost driver. With the Forschungszulage, you can cushion this phase from a tax perspective, if your prototype is functional, addresses technical uncertainties, and you document systematically.

If you wish, zeitmaker.com can review your project in advance – so you quickly know what is realistically eligible and how to optimally structure the prototype phase.


Frequently asked questions

Yes, if the prototype is part of a systematic innovation process and the focus is on gaining knowledge (tests, iterations, validation).

Often not eligible: show models, design studies without technical function, pre-series/near-series implementation, and prototypes where the primary goal is market entry rather than technical clarification.

Often yes – if novel algorithms/models or experimental architectures are developed and technically validated (with documented tests/iterations). ( /blog/can-i-get-public-funding-for-my-software-project )

Not automatically – and usually not. What is generally eligible is the direct technical innovation work (e.g. development, tests, iterations on the functional prototype) – not "everything that occurs within the project". Important: Depending on the funding logic/program, there may be exceptions (e.g. dedicated modules for network management or market launch activities). For the Forschungszulage, however, the rule remains: the decisive factor is the direct contribution to technical knowledge gain; marketing/classic project management are typically not included.
