Forschungszulage or Invest BW? Funding Comparison
Invest BW or Forschungszulage? Compare predictability, effort, risk and funding amount for your innovation project in Baden-Württemberg.
Many companies hear about the Forschungszulage — and then stumble at a central step in the process: the certification. This is exactly where the Bescheinigungsstelle Forschungszulage (BSFZ) comes in. Understanding what the BSFZ reviews, when it appears in the process and which requirements need to be met saves time, reduces follow-up questions and increases the chance of a successful Bescheinigung Forschungszulage.
The Bescheinigungsstelle Forschungszulage (short: BSFZ) is the body that assesses on a substantive level whether a submitted R&D project meets the criteria of the Forschungszulagengesetz (FZulG). In simple terms:
The BSFZ does not decide on the payment — but it decides on whether your project qualifies as eligible R&D at all.
Important to understand: The BSFZ Forschungszulage is therefore the gatekeeper in the process. Without its positive certification, the path to the Forschungszulage is effectively blocked.
The Forschungszulage runs in two clearly separate steps:
You first apply for the Bescheinigung Forschungszulage via the official digital process. The BSFZ reviews the substantive eligibility of your project.
Only after the BSFZ certification do you submit the application for assessment to the tax office. The Forschungszulage is then taken into account for tax purposes (offset/refund as part of the tax assessment).
The BSFZ carries out the following core tasks:
An important point: the BSFZ assesses the substance — it is not the body that sets your tax. That is done later by the tax office.
The BSFZ reviews whether your project falls into one of the R&D categories, typically:
In addition, projects must in practice demonstrably meet the well-known criteria, for example:

Often, success is determined even before you click anything:
The application is submitted entirely digitally via the portal for the Bescheinigung Forschungszulage. Typical information requested:
The BSFZ assesses whether the project meets the requirements. The clearer and more consistent your R&D argument (problem, state of the art, uncertainty, solution approach), the lower the risk of follow-up questions or rejection. (Read more here about what happens if the BSFZ rejects your application).
After a positive review you receive the BSFZ certification and can then (after the end of the financial year in which costs were incurred) submit the application for assessment to the tax office.
The BSFZ is decisive because it:
In practice this means: whoever underestimates the BSFZ (e.g. with too vague a project description, no clear uncertainty, routine development) risks delays or rejection — even if the project seems "innovative".
The Bescheinigungsstelle reviews and decides — it does not optimise your application strategically. If you lack the experience, structured internal preparation or external support is worthwhile.
Typical mistakes:
Better approach:
A plausible work plan is not an "extra" — it is often the key to comprehensibility:
Even if not every piece of evidence needs to be uploaded at the BSFZ stage: the logic must be sound — and in case of doubt, documentation must be available internally. Keeping clean records from the start saves enormous effort later.
| Body | Task | Outcome |
|---|---|---|
| BSFZ (Bescheinigungsstelle Forschungszulage) | Substantive R&D review under FZulG | Bescheinigung Forschungszulage (certification) |
| Tax office | Tax assessment/offset (after financial year) | Assessment notice / tax effect |
The Forschungszulage is fundamentally relevant for all tax-liable companies — regardless of industry or size. Those who benefit most frequently include:
The Bescheinigungsstelle Forschungszulage (BSFZ) is the central lever in the entire process. It reviews whether your project actually constitutes R&D in the sense of the Forschungszulagengesetz and issues the Bescheinigung Forschungszulage. Only after that can the tax office assess the allowance.
If you clearly document the requirements (novelty, uncertainty, systematic approach), have a clear work plan and present your R&D logic coherently, the application process becomes significantly easier — and your project has a good chance of being successfully certified.
The BSFZ is the body that, in the Forschungszulage application process, reviews whether your project qualifies as R&D under the FZulG. If the review is positive, it issues the Bescheinigung Forschungszulage (certification).
No. The Bescheinigungsstelle Forschungszulage reviews applications but does not provide individual advice on how to present or structure your application optimally.
Always go to the BSFZ first. Without the BSFZ certification, you cannot obtain a Forschungszulage assessment from the tax office.
In practice, up to around three months is commonly estimated for the BSFZ review — in addition to the internal preparation time within the company.
Common causes include project descriptions that are too general, insufficient documentation of technical uncertainty, unclear delineation from the state of the art, or an implausible or missing work plan.
The application is submitted entirely digitally via the official portal for the Bescheinigung Forschungszulage.
