Forschungszulage requirements: who is eligible?

Does my project meet the R&D criteria?

This is where it gets interesting — and where most applications fail. What is actually funded? Not just basic research. The vast majority of funded projects fall into experimental development: there's an unsolved technical problem and you systematically test a solution.

Research has three categories — and most development in companies falls under one of them§ 2 FZulG§ 2 FZulG: Begünstigt sind Vorhaben der Grundlagenforschung, industriellen Forschung und experimentellen Entwicklung, eigenbetrieblich, als Auftragsforschung oder in Kooperation. Nicht mehr begünstigt sind Tätigkeiten, deren primäres Ziel die Marktentwicklung ist oder die ein festgelegtes Produktionssystem zum reibungslosen Funktionieren bringen sollen.

1. Basic research — New scientific knowledge without direct application
2. Industrial research — Systematic research with a concrete application goal
3. Experimental development — Using existing knowledge to develop new or improved products, processes, or software (← where most applications land)

The three decisive criteria

Your project must answer these three questions with yes:

• Novelty: Does your project aim for new knowledge or significantly improved products / processes — measured against the current state of the art?Prüfleitfaden Ch. 1.1.1Prüfleitfaden Ch. 1.1.1: „Neuartig ist ein FuE-Vorhaben dann, wenn es auf den Erwerb neuen Wissens abzielt. Dieses Wissen muss über den aktuellen Stand der Technik hinausgehen.“
• Uncertainty (Risk): Are there technical risks or uncertainties? Could your approach fail? Purely economic risks do not count.Prüfleitfaden Ch. 1.1.2Prüfleitfaden Ch. 1.1.2: „Die BSFZ bezieht sich bei der Bewertung des Kriteriums Unwägbarkeit / Risiko ausschließlich auf wissenschaftliche und technische Aspekte. Wirtschaftliche Risiken und Unwägbarkeiten werden zur Beurteilung, ob ein FuE-Vorhaben im Sinne des FZulG vorliegt, nicht herangezogen.“
• Systematic approach: Is the project carried out in a planned and documented manner?Prüfleitfaden Ch. 1.1.3Prüfleitfaden Ch. 1.1.3: „Planmäßig ist ein FuE-Vorhaben, wenn es einer systematischen Vorgehensweise folgt, deren Ziele, Methodik und zeitlicher Ablauf nachvollziehbar dokumentiert sind.“

Behind these three review criteria is the OECD's Frascati Manual. It describes R&D with five features: novel, creative, uncertain, systematic, and transferable and/or reproducible. The BSFZ condenses them into its three criteria, with “creative” absorbed into novelty and uncertainty. For a deeper dive, there is one article each on novelty, creative work, uncertainty and the systematic approach.

The Red Thread: How to argue R&D

The BSFZ reviewers think in exactly this framework: Where are you today? → What are you doing? → Where do you want to go?Prüfleitfaden Ch. 1.1.1Prüfleitfaden Ch. 1.1.1: „Jeder Forschungs- und Entwicklungsprozess besteht aus drei wesentlichen Teilen: Start/Ausgangslage, Weg zur Umsetzung, Ziel: Produkt, Verfahren oder Dienstleistung.“

Each of these three points must be described in technical, concrete terms. Economic targets like "50% more revenue" or "better user experience" will not convince the certification body.

The most common mistake: the state of the art is described vaguely or in market terms

The BSFZ wants concrete, technical benchmarks — and the reviewers immediately recognise whether someone knows their field. Many companies conduct genuine experimental development without framing it that way — leaving hundreds of thousands or even millions in funding on the table.

Checklist: R&D or not?

Prototype, pilot line, trial production: where R&D ends

For the Forschungszulage, a prototype is not a first sample for sales or a pitch but a functional interim state that answers technical questions. Whether it is physical (component, machine) or digital (software demonstrator, algorithm, AI model) hardly matters. Development is typically eligible when

• genuine technical uncertainties exist, for example in function, integration, scaling or performance,
• you proceed systematically: plan, build, test, refine,
• the prototype serves to gain knowledge, for example through tests under realistic conditions.

The line runs where knowledge gain ends and market or operational logic begins. A pilot line still counts as long as it mainly delivers technical data and experience. Trial production that already prepares the series launch usually does not. Also typically not eligible:

• design studies and models without a technical function,
• pre-series, series development and product adaptations without new technical findings,
• marketing and sales, even if they belong to the project,
• pure project steering (status, budget, deadlines) without a technical share.

"Part of the project" does not automatically mean "eligible". So set the project end at the first functional prototype or the completion of technical testing.

What is funded by the Forschungszulage?

• Wage costs for employees in R&D projects
• Own work by sole traders / co-entrepreneurs
• Contract research (70% of expenditures)
• Depreciation on movable fixed assets related to the project

Application deadline

Costs for R&D activities can be claimed within a 4-year period. The decisive factor is the date the application is received by the BSFZ.

The Forschungszulage is particularly attractive because you can apply retroactively. Unlike European funding programmes where you plan future projects and then report extensively, here you claim costs that have already been incurred. No planning stress, no reporting problems.

Proving eligibility

The Forschungszulage is granted through a two-step process:

1. Content review (BSFZ)— Assesses whether your project meets the R&D criteria. Prüfleitfaden Ch. 1.2Prüfleitfaden Ch. 1.2: „Bezogen auf die Angaben zum finanziellen und personellen Rahmen wird durch die BSFZ eine Plausibilitätsprüfung „dem Grunde nach“ durchgeführt.“ More on the application process →
2. Financial review (tax office) — Reviews the actual expenditures (wage costs, timesheets, employment contracts). More on calculation →

The two stages check different things, but they interlock: whatever is not cleanly delimited in the BSFZ certificate can hardly be rescued on the numbers side at the tax office. That seam is exactly where Forschungszulage consulting comes in: it delimits the project cleanly in the BSFZ application and supplies the matching cost breakdown and a pre-filled ELSTER form for your tax advisor to review and file.
