Incentives That Work: Germany’s R&D Research Allowance (Forschungszulage)

In recent years, Germany introduced a new federal R&D incentive known as the Research Allowance (Forschungszulage) to support business innovation. Prior to this change, Germany historically offered generous direct grants for research projects but had limited tax credits. The Research Allowance Act (Forschungszulagengesetz), which came into effect on January 1, 2020, now provides companies of all sizes with a refundable tax credit for qualifying research and development activities. This post explores how the Research Allowance works, including qualification criteria, how the credit is calculated, documentation requirements, payout mechanisms, and how it compares with the U.S. federal R&D tax credit. 

What Is the Research Allowance?

Germany’s Research Allowance is a federal R&D incentive that provides a tax‑based subsidy for companies that carry out qualified research and development projects within Germany. Instead of traditional deductions, this incentive functions as a tax credit or refundable subsidy that can reduce a company’s tax burden and even result in a cash payout if the credit exceeds tax liability.

Under current rules, the credit is generally 25% of eligible R&D expenditures, with an enhanced rate of 35% for small and medium‑sized enterprises (SMEs). Eligible R&D expenditures are capped at €12 million ($14.18m USD) per year, meaning the maximum credit a company can claim annually is €3 million or up to €4.2 million for SMEs ($3.55m and $4.96m USD, respectively).

Who Qualifies?

Unlike Canada’s CCPC requirements or the U.S. four-part test, the German Research Allowance is available to all taxable companies operating in Germany, regardless of size, industry, or corporate structure, as long as they are taxed on their income in Germany. Both resident companies and non-resident companies with a sufficient German permanent establishment can qualify, which means the foreign company must have a fixed place of business in Germany, such as a branch, office, or lab, that is actively engaged in the R&D project.

To benefit from the Research Allowance, companies must conduct qualified R&D activities defined by EU research classifications: basic research, industrial research, or experimental development. These activities must have technological elements that extend beyond routine quality control or market research.

Compared with the U.S. federal R&D tax credit, this definition is stricter in that it ties eligibility to formal research classifications and clearly excludes work that is commercially routine. The U.S. credit also excludes routine or non-technical activities but allows a broader range of experimental work, including incremental improvements or applied experimentation on products or processes, as long as the project satisfies the statutory four-part test.

Additionally, companies must obtain a certificate from an official R&D certifying body confirming that the project qualifies for the Research Allowance. This certificate is then submitted to the tax office along with the company’s tax return.

Eligible Expenditures

Eligible expenses for the Research Allowance focus primarily on costs that are directly associated with R&D work:

• Personnel costs for employees conducting R&D, including employer social security contributions
• Contract research expenses paid to external service providers (often with a percentage of the cost qualifying)
• Depreciation of movable assets used exclusively for R&D, provided they were acquired after recent eligibility changes

Starting in 2026, Germany has also introduced a flat‑rate 20% overhead allowance to cover indirect operating costs tied to R&D projects, expanding the base of qualified expenses without requiring detailed documentation for each cost. This change makes the incentive more generous and easier to claim.

Calculation and Payout

The Research Allowance is calculated based on the assessment basis of eligible R&D expenditures, up to the annual cap. For example, if a company incurs €10 million in qualifying expenses and is an SME, it may be eligible for a €3.5 million allowance, which is approximately $3.8 million USD (35% of €10 million). Larger companies typically receive 25% of eligible expenses, yielding up to €3 million (~$3.3 million USD).

Unlike many non‑refundable credits in other jurisdictions, the Research Allowance is credited against the corporation tax assessed and can be paid out as cash if the allowance exceeds tax liability. This means that companies with low or no taxable income—such as startups or firms investing heavily in early-stage development—can still receive a refund for their R&D activities.

The Research Allowance can be claimed retroactively for several years, allowing companies to include past R&D work that began after the incentive was introduced in 2020.

Documentation and Compliance Requirements

Although the documentation requirements for the German Research Allowance are less prescriptive than some grant programs, companies must still provide evidence that:

• An R&D project exists with clear objectives and scope
• Eligible expenditures are linked to the project
• A certification from the official R&D certifying body confirms the project’s qualification

Once the certifying body issues the eligibility certificate, the Research Allowance application is submitted with the company’s tax return. If the allowance exceeds the assessed tax, the surplus is refunded. Unlike Canada or the U.S., there is no carry-forward of unused credits; instead, the credit is fully applied in the year claimed and refunded if in excess.

Comparison with the U.S. R&D Tax Credit

There are several notable differences between Germany’s Research Allowance and the U.S. federal R&D tax credit:

• Refundability: The German Research Allowance is effectively refundable, meaning companies can receive cash even if they have little or no tax liability. The U.S. federal credit, by contrast, is generally non-refundable, though small businesses can elect to apply part of the credit against certain payroll taxes.
• Qualification Process: Germany requires certification from an official R&D certifying body and adherence to EU research classifications, whereas the U.S. relies on the statutory four-part test defined in Section 41 of the Internal Revenue Code and IRS guidance.
• Eligible Costs: Germany’s incentive focuses heavily on personnel costs, contract R&D, and depreciable assets, with overhead support introduced recently. The U.S. credit allows wages, supplies, leasing costs, and some contract research but does not include depreciation of capital assets.
• Carry Mechanisms: The German allowance applies in the tax year claimed and is refunded if unused, whereas the U.S. credit can be carried back one year and forward up to 20 years to offset tax liability.
• Documentation: Both systems require documentation linking expenses to qualified research, but Germany’s process is tied to certification by an external R&D authority prior to tax filing, while the U.S. system attaches documentation to satisfy the IRS’s audit requirements.

Practical Considerations

For companies considering the German Research Allowance:

• Plan early to obtain the required R&D certification, as it is a prerequisite for claiming the allowance
• Track all personnel, contract, and eligible asset costs associated with R&D projects
• Use the flat-rate overhead allowance when available to simplify cost capture
• Evaluate how the refundability aspect can improve cash flow, especially for startups and high-growth firms

Germany’s Research Allowance represents a significant step in strengthening R&D incentives in a jurisdiction that traditionally relied more on direct grants and public funding for innovation. With refundable features, generous caps, and broad eligibility across industries, it complements other European and North American R&D incentives while offering a unique approach to accelerating investment in technological development.
