Key Facts at a Glance
The research allowance (Forschungszulage) is a German R&D tax incentive under the Research Allowance Act (FZulG). It amounts to 25% of eligible expenses, or 35% for SMEs upon request. The assessment basis has been capped at EUR 12 million per year since January 1, 2026; the maximum allowance is EUR 4.2 million. The procedure has two stages: BSFZ application, then tax office application (Annex FZ). All companies taxable in Germany with R&D activities qualify – retroactively for up to four years.
FZulG Key Figures (Legal Status 2026)
The research allowance is a German tax incentive for research and development under the Research Allowance Act (FZulG). It applies to all industries and topics, regardless of company size. The table below summarizes all central values – each row is individually citable.
| Parameter | Value | Note / Legal Basis |
|---|---|---|
| Funding rate (standard) | 25% of the assessment basis | Section 4 FZulG |
| Funding rate SMEs | 35% | Increase by 10 percentage points upon request, Section 4 FZulG |
| Assessment basis | EUR 12 million per year | from January 1, 2026; history: EUR 10 million for March 27, 2024 – December 31, 2025 |
| Maximum allowance | EUR 4.2 million per year | 35% of EUR 12 million (SME rate) |
| Overhead allowance | 20% | Section 3 (3b) FZulG, for eligible expenses from January 1, 2026 |
| Own contributions | EUR 100 per working hour | max. 40 h/week, for sole proprietors and shareholders with an activity agreement |
| Contract research | 70% of the fee | eligible share on the client side |
| Procedure | two stages | 1. BSFZ application, 2. tax office application (Annex FZ) |
| Retroactivity | up to 4 years | can be claimed retroactively, including completed projects |
| R&D criteria | Novelty · Technical Risk · Systematic Approach | all three criteria must be met |
Effectively up to 42% of Personnel Costs for SMEs
Since January 1, 2026, the 20% overhead allowance (Section 3 (3b) FZulG) automatically increases the assessment basis. For SMEs this means: effectively up to 42% of personnel costs (35% funding rate on 120% assessment basis thanks to the 20% overhead allowance).
- Eligible R&D personnel costs: EUR 100,000
- + 20% overhead allowance → assessment basis EUR 120,000
- SME rate 35% × EUR 120,000 = EUR 42,000 research allowance
- EUR 42,000 relative to EUR 100,000 personnel costs = 42% effective rate
For companies at the standard 25% rate, the effective rate is 30% of personnel costs (25% on 120%). The overhead allowance requires no separate documentation – it is applied as a flat surcharge on eligible expenses.
Two-Stage Procedure: BSFZ and Tax Office Application
The path to the research allowance consists of exactly two applications to two different authorities. The order is fixed: BSFZ first, then the tax office.
Stage 1: BSFZ Application
The certification body for the research allowance (BSFZ) checks the substantive eligibility of R&D projects against the three criteria Novelty, Technical Risk and Systematic Approach. The result is a certificate that is binding for the tax office. The application is filed digitally via the BSFZ portal; one application can cover several projects.
Stage 2: Tax Office Application (Annex FZ)
After receiving the BSFZ certificate, the allowance is claimed via the Annex FZ at the responsible tax office – one annex per fiscal year. The tax office sets the research allowance and credits it against income or corporate tax with the next assessment; any surplus is paid out. The incentive therefore also works in loss-making years.
R&D Criteria: Novelty, Technical Risk, Systematic Approach
Whether a project is eligible is decided not by industry but by three criteria (based on the OECD Frascati Manual). All three must be met at the same time:
All three R&D categories are eligible: basic research, industrial research and experimental development. Routine development, product maintenance and market launch activities are not eligible.
Eligibility by Industry
The matrix shows typical project examples from six industries. Projects with Technical Risk are eligible – routine work is not. The classification is a guide; the individual case is always assessed against the three R&D criteria.
| Industry | Typically eligible | Typically NOT eligible |
|---|---|---|
| Software/SaaS | Novel algorithms or system architectures with Technical Risk; real-time data processing beyond established frameworks | Routine adaptations, CRUD apps, configuration of standard software |
| AI/Machine Learning | Own model architectures, new training or optimization methods; ML for use cases without an established solution | Use of ready-made models or APIs without own research; plain prompt configuration |
| Mechanical Engineering | New manufacturing processes, functional prototypes with an open technical outcome, novel material combinations | Design based on the known state of the art, customer-specific variants |
| Electrical Engineering | Novel circuit or sensor concepts, power electronics at physical limits | PCB layout using standard methods, swapping individual components |
| MedTech/Pharma | New drug candidates, novel diagnostic methods, clinical research phases | Pure regulatory documentation, marketing studies |
| GreenTech | New storage, recycling or electrolysis processes; efficiency gains beyond the state of the art | Installation of market-ready systems, standard energy audits |
Key Terms in Brief
Five terms that appear in every FZulG procedure – each defined in one sentence:
- FZulG: The German Research Allowance Act, in force since January 1, 2020 – the legal basis of the research allowance.
- BSFZ: The certification body for the research allowance; it checks the R&D criteria and issues the certificate that is binding for the tax office.
- Annex FZ: The tax form for the tax office application (German: Anlage FZ) – one annex per fiscal year.
- Assessment basis: The sum of eligible expenses (personnel costs, own contributions, 70% of contract research, overhead allowance), capped at EUR 12 million per year.
- SME: A company with fewer than 250 employees and at most EUR 50 million turnover or EUR 43 million balance sheet total (EU definition) – the requirement for the 35% rate.
