Forschungszulage Personnel Costs: Guide (2026)
How to claim R&D personnel costs via the Forschungszulage: eligible costs, calculation methods, 2026 limits and audit-proof documentation explained.
Many good innovation projects fail not because of the idea but because of financing. This is exactly what Saarland emphasizes: the goal is that no viable future project in the state should "fail due to a lack of funds." At the same time, practice shows that companies that wait for individual programs lose time – or miss budgets and deadlines.
My recommendation: set up your funding logic correctly. Regional programs can be very attractive – but the Forschungszulage is for many companies the stable, repeatable core, because it ties directly to your innovation activities rather than a regional budget pot.
On 03.02.2026, Saarland presented additional funding options via the Saarländische Investitionsbank (SIKB) – particularly for SMEs and startups. The package contains three instruments:
This is a strong signal: innovation should be financed faster – through better interest terms, improved capital structure, and equity proximity.
Regional programs (such as the Saarland package) frequently address financing questions: making credit cheaper, substituting or supplementing equity, providing growth capital.
The Forschungszulage typically intervenes earlier – at the innovation expenditure itself. From an advisory perspective, this is the decisive advantage: you strengthen your innovation budget directly where costs arise (personnel, projects, development steps), rather than "merely" making financing cheaper.
| Criterion | Regional programs (e.g. Saarland 02/2026) | Forschungszulage (federal) |
|---|---|---|
| Goal | Make financing easier (interest, capital, creditworthiness) | Reduce innovation expenditure through tax relief |
| Dependence on budgets | Often yes (programs / pots / region) | Generally more plannable, nationwide |
| Typical hurdle | Program fit, conditions, availability | Clean project documentation & evidence logic |
| Application | Investments, growth, financing | Continuous innovation work |
If innovation is part of your strategy (not just a one-off project), you need an instrument that can be repeatedly integrated into your planning.
In many cases the smart approach is: Forschungszulage as the base + regional programs for financing, scaling, interest relief, or equity structure.
That is exactly what the quick calculator and the detailed calculator on zeitmaker.com are for – so you can estimate early on how large the leverage is for your innovation budget.
https://www.bescheinigung-forschungszulage.de/The new Saarland instruments are a good example of how states want to accelerate investment and growth – through cheaper interest, better capital structure, and equity capital. For most innovating companies, however, the key principle holds: anyone who wants to finance innovation on an ongoing basis needs a robust baseline funding source. In practice, the Forschungszulage is often the most effective starting point – and can then be intelligently combined with regional offerings.
A package worth €65 million comprising interest subsidies (€7M), subordinated loans (€35M, partly EU-funded) and equity capital (€22.6M) via the SIKB, with a focus on SMEs and startups.
Not categorically. Regional programs make financing and scaling easier through interest subsidies, loans, or equity. The Forschungszulage is often the better long-term baseline because it directly reduces the tax burden on ongoing innovation costs.
Yes, often. What matters is a clean separation of costs, a clear application roadmap, and the right documentation strategy so the funding logics do not cancel each other out.

Missing funding-logic documentation. If your project logic, evidence, and cost separation are clean from the start, you save time and avoid follow-up questions from the BSFZ and the tax office.
