Can I get the Forschungszulage retroactively? Here's how
You can apply for the Forschungszulage retroactively—up to 4 years. Learn how the process works, the best strategy, and what to watch out for.
With the Forschungszulage, the rule is: If your project meets the R&D criteria, you have a legal entitlement. You do not compete with other companies for limited budgets as with classic grants. This creates planning certainty—especially when R&D is designed for the long term.
A major lever is retroactivity: You can claim the Forschungszulage after the fact for eligible R&D expenses (typically within the scope of the tax assessment limitation periods). This is especially helpful if you only realize later that a project actually qualified as "R&D"—or if a project has already been completed.
Whether start-up, SME, or corporation: the Forschungszulage is not tied to a specific sector. What matters is not your industry, but whether your activity can be classified as research/industrial research/experimental development.
Many funding instruments help only "at some point later"—the Forschungszulage can also have an impact when there are no profits and therefore no or low tax burden: If the assessed Forschungszulage exceeds the tax due, it can be paid out. This is a relevant liquidity advantage, especially for growth-oriented companies.
Compared to many project grants, the Forschungszulage is often leaner:
Important: "Leaner" does not mean "anything goes"—a well-prepared project description and documentation saves time and follow-up questions later.
The application steps are digital: project certification via the BSFZ portal, and the tax claim via the tax return/ELSTER. This reduces paperwork, improves traceability, and makes the process more workable for many teams.
There is no rigid topic catalogue like with many programs. Projects are supported if they qualify as R&D (e.g., experimental development, industrial research). This makes the Forschungszulage a good fit for product-close development—for example in software, mechanical engineering, electronics, MedTech, or process innovation.
A typical core component is personnel costs for employees working in R&D. Depending on the setup, additional cost types may also be eligible (e.g., contract research as well as, under certain conditions, depreciation-related costs for assets used in the project context). This means the Forschungszulage can also work for more complex development setups.
In principle, all companies taxable in Germany, regardless of sector, size, or legal form—provided they carry out an eligible R&D project.
Typically, projects that are novel, systematic, and involve technical/scientific uncertainty (e.g., experimental development or industrial research). Pure routine improvement without risk/uncertainty is often not sufficient.
Not necessarily. A major benefit is that the Forschungszulage can be claimed retroactively (within the tax time limits). Still, it pays to document things cleanly early.
Usually two-step: first the BSFZ certification for the project, then the claim with the tax office via the tax return.
Yes. If the Forschungszulage exceeds the assessed income/corporate tax—or if no tax is due—it can be paid out as a refund.
