Germany’s economic landscape shifted significantly on 28 March 2024, when the Wachstumschancengesetz (Growth Opportunities Act) entered into force. Bundling over 50 tax measures into a single piece of legislation, the Act is the German government’s most significant tax stimulus package in years, designed to reinvigorate investment, support SMEs, and accelerate the country’s digital transformation.
For finance and treasury teams, the implications are immediate and practical: new depreciation rules, expanded R&D tax credits, updated loss carryforward limits, and, most critically, a mandatory shift to B2B e-invoicing that reshapes payment workflows across every sector.
This guide breaks down everything businesses operating in Germany need to know, from the key tax measures and compliance deadlines to the fraud risks that come with digitizing your payment operations.
Key Takeaways
- The German Growth Opportunities Act (Wachstumschancengesetz) entered into force on 28 March 2024, delivering a €3.2 billion tax relief package aimed at stimulating investment and competitiveness.
- SMEs benefit from enhanced R&D tax incentives, with the research allowance rate rising to 35% and the eligible expenditure cap reaching €10 million per year.
- Mandatory B2B e-invoicing was introduced from 1 January 2025, with transitional rules depending on company turnover.
- Temporary declining-balance depreciation was reintroduced for movable assets and residential construction, improving near-term cash flows.
- Businesses transitioning to e-invoicing face heightened payment fraud risk, automating vendor bank account validation is a critical part of any compliant finance operation in Germany today.
What Is the Growth Opportunities Act in Germany?
The Growth Opportunities Act, officially the Wachstumschancengesetz (Gesetz zur Stärkung von Wachstumschancen, Investitionen und Innovation sowie Steuervereinfachung und Steuerfairness), is a German federal law enacted on 28 March 2024.
Its primary purpose: reverse Germany’s economic slowdown by making the country a more attractive place to invest, innovate, and operate. Drafted by the Federal Ministry of Finance and passed by the Bundestag on 23 February 2024 following negotiations in the mediation committee, it was approved by the Bundesrat (Federal Council) on 22 March 2024 and came into force six days later.
The law bundles over 50 individual tax measures across depreciation, loss utilization, research incentives, bureaucracy reduction, and digitalization mandates, with a total estimated fiscal relief of €3.2 billion.
For finance and treasury teams, the most operationally significant change is the mandatory shift to e-invoicing, a transition that reshapes payment workflows and, with it, the risk of payment fraud. Platforms like Trustpair help businesses navigate this transition securely by continuously validating vendor bank account data in real time.
What Are the Main Goals of the Growth Opportunities Act?
The Act is built around three strategic pillars:
- Strengthening investment and innovation — through better depreciation rules, loss carryforward flexibility, and expanded R&D tax credits.
- Supporting SMEs — through simplified accounting thresholds, VAT relief, and preferential research funding rates.
- Reducing bureaucracy — including the landmark shift to mandatory e-invoicing, designed to cut over €1.3 billion in administrative costs.
Sectors covered span manufacturing, technology, retail, real estate, and services. The Act is not sector-specific, but its practical impact is most pronounced for capital-intensive businesses and those with significant R&D expenditure.
What Are the Key Tax Measures in the Growth Opportunities Act?
Temporary increase to the loss carryforward limit
For assessment periods 2024 to 2027, the minimum tax rule for income tax and corporation tax is temporarily relaxed. Loss carryforwards for amounts exceeding €1 million can now be deducted up to 70% of total income, up from the previous 60% cap. This directly improves cash flow for businesses recovering from loss-making years.
Reintroduction of declining-balance depreciation
The Act reintroduces declining-balance depreciation for movable fixed assets acquired or manufactured between 1 April 2024 and 31 December 2024. The applicable factor can be up to twice the straight-line rate, capped at 20% annually.
This means businesses can front-load depreciation, reducing taxable income in the critical early years of an asset’s life, a meaningful advantage for capital expenditure planning.
Increase to the cash-basis accounting threshold
The turnover threshold above which businesses are required to keep full accrual-basis accounts has been raised to €800,000 for financial years starting from January 2024. Smaller businesses below this threshold may use the simpler cash-basis method, significantly reducing accounting overhead.
Increased gift exemption limit
The deductible limit for business gifts to third parties has been raised from €35 to €50 per recipient per year. While modest in isolation, this simplification reduces the administrative burden of tracking gift expenses for tax purposes.
What Are the Exemption Limits and Small Business Reliefs?
VAT exemption for small entrepreneurs
Small entrepreneurs (Kleinunternehmer) benefit from updated VAT return rules. The threshold adjustments align with the EU’s SME VAT Directive and allow qualifying businesses to operate without charging VAT, while streamlining their reporting obligations.
Key compliance note: Businesses operating near these thresholds must monitor their turnover closely. Exceeding exemption limits (even by a small margin) triggers full VAT obligations for the following year.
How Does the Growth Opportunities Act Change the Research Allowance?
The research allowance (Forschungszulage) receives some of the most substantial upgrades in the Act, making Germany’s R&D tax credit significantly more competitive internationally.
New eligible expense threshold: €10 million
The maximum annual assessment basis for the research allowance has been removed from its previous cap and extended to €10 million per year. At the standard rate, this means eligible companies can now claim up to €2.5 million annually in research tax credits.
SME uplift to 35%
Standard beneficiaries receive a funding rate of 25% of the assessment basis. However, SMEs (within the EU GBER definition) can apply for an increased rate of 35%, offering a meaningful additional incentive for smaller innovative firms.
Expanded eligible expenditure categories
The following changes significantly broaden what qualifies:
- Depreciable movable assets used directly in an R&D project are now eligible (previously excluded).
- The eligible share of contract research costs rises from 60% to 70%.
- Self-employed R&D work is now calculated at €70 per proven hour (up from €40).
Practical advice: Businesses with active R&D programmes should review whether previously excluded asset or contractor costs now qualify. Documenting eligible costs with timestamps and project descriptions before year-end is critical for a successful BSFZ certification application.
How Do Businesses Apply for the Research Allowance?
The research allowance is not automatic. Companies must:
- Apply to the BSFZ (Bescheinigungsstelle Forschungszulage) for project certification.
- Submit supporting documentation including project descriptions, employee time records, and invoices for contracted R&D.
- File a research allowance claim with the tax authority (Finanzamt) once certified.
Note: limitation periods apply to project expenses incurred in prior years. Costs from 2020, for example, must still have been applied for in 2024. Acting promptly avoids forfeiting eligible relief.
What Are the Mandatory E-Invoicing Requirements Under the Growth Opportunities Act?
Why e-invoicing is the Act’s most operationally significant change
From 1 January 2025, mandatory electronic invoicing applies to all B2B transactions between companies domiciled in Germany. This is one of the most impactful operational changes for finance teams, affecting accounts payable, treasury, and procurement processes simultaneously.
Accepted formats include:
- XRechnung (the German domestic standard)
- ZUGFeRD (a hybrid PDF/XML format)
- Any format compliant with EN 16931, the European e-invoicing standard
For a full breakdown of format requirements, see our guide on e-invoicing requirements in Germany and our comparison of XRechnung vs. ZUGFeRD. Businesses should also be aware of the EDI vs. PEPPOL distinction when evaluating their technical infrastructure. (See: What Is the Difference Between EDI and PEPPOL?)
Transitional rules for e-invoicing
- From 1 January 2025: All businesses must be able to receive structured e-invoices.
- From 1 January 2027: Companies with prior-year turnover above €800,000 must issue e-invoices.
- From 1 January 2028: All remaining companies must issue e-invoices.
- Until end of 2027: Paper invoices and PDFs remain valid with prior agreement between parties.
Recommended steps for technical readiness:
- Audit your current AP/AR systems for e-invoicing capability.
- Test XRechnung and ZUGFeRD workflows with key suppliers before deadlines.
- Update your ERP or accounting platform to support EN 16931-compliant formats.
E-invoicing and the fraud risk dimension
The shift to e-invoicing introduces a frequently overlooked compliance risk: invoice fraud and payment redirection attacks. When payment instructions flow digitally at scale, the risk of fraudulent supplier bank account changes or fake invoice injection increases significantly. Read more on how third-party fraud threatens businesses during periods of process change.
This is precisely where Trustpair adds critical value. Trustpair continuously validates vendor bank account data against a global network of banking sources, ensuring that every payment instruction, including those arriving via e-invoice workflows, is routed to a verified, legitimate account. For finance teams managing Germany’s e-invoicing transition, automating bank account validation is not optional: it is a core component of a complete compliance posture.
What Are the Electric Vehicle Tax Benefits Under the Growth Opportunities Act?
For employers providing company cars for private use, the Growth Opportunities Act increases the acquisition price threshold for fully electric vehicles from €60,000 to €70,000. Vehicles below this price point qualify for the preferential 0.25% monthly private-use tax rate, compared to the standard 1% rate applied to combustion engines.
Employer action: Review fleet policies to assess whether current or planned EV models fall within the new threshold. The change directly affects taxable benefit calculations for employees using company EVs privately.
How Does the Act Support Residential Construction and Depreciation?
The Act introduces declining-balance depreciation for residential construction projects. Applicable to buildings where construction begins after 1 October 2023, the measure allows developers to depreciate at 5% per year using the declining-balance method.
Updated construction cost caps per square meter also apply, reflecting current market realities and improving the economic viability of new housing development.
Developer note: Eligibility and calculation rules for special depreciation should be reviewed with a qualified tax advisor. The declining-balance method offers significant front-loading benefits, but requires careful application in the initial tax return.
What Roles Did the German Federal Council and Federal Ministry Play?
The Growth Opportunities Act was subject to an unusually complex legislative journey:
- The Federal Ministry of Finance drafted the original bill, initially estimated at approximately €7 billion in relief.
- The Bundesrat (Federal Council, representing Germany’s 16 states) blocked the initial version in November 2023, citing concerns over the revenue impact on state budgets.
- A Mediation Committee (Vermittlungsausschuss) brokered a compromise, scaling back several measures and removing the proposed climate protection investment premium entirely.
- The revised bill passed the Bundestag on 23 February 2024 and received Bundesrat approval on 22 March 2024.
The result is a more modest package than originally proposed, but still represents the largest tax stimulus for German businesses in recent years.
What Are the Key Compliance Deadlines and Practical Steps?
- 28 March 2024: Research allowance expansion, gift exemption limit raised to €50, EV acquisition price cap raised to €70,000.
- Assessment periods 2024–2027: Loss carryforward deduction increased to 70%.
- April–December 2024: Window for assets eligible for reintroduced declining-balance depreciation.
- Financial years from January 2024: Cash-basis accounting threshold raised to €800,000.
- 1 January 2025: Mandatory e-invoice receipt capability for all German companies.
- 1 January 2027: Mandatory e-invoice issuance for companies with turnover above €800,000.
- 1 January 2028: Mandatory e-invoice issuance for all remaining companies.
Recommended action steps:
- Update accounting, payroll, and ERP systems to reflect new thresholds and depreciation rules.
- Engage a qualified tax advisor before year-end to maximize depreciation and loss utilization elections.
- Commission a readiness assessment for e-invoicing infrastructure.
- Review vendor bank account data hygiene in parallel with your e-invoicing rollout. Trustpair ensures your vendor data is always accurate, complete and secure.
How Can Businesses Claim Benefits Under the Growth Opportunities Act?
Some benefits apply automatically via standard tax return processes:
- Declining-balance depreciation elections
- Loss carryforward deductions
- Gift exemption limit changes
- EV private-use tax benefit
Others require proactive steps:
- The research allowance requires BSFZ project certification before you can claim.
- E-invoicing readiness requires technical investment and proactive supplier communication.
Documentation is non-negotiable. For the research allowance in particular, retroactive documentation is rarely accepted. All eligible R&D activities should be recorded contemporaneously — including time sheets, project descriptions, and contractor agreements.
