Wachstumschancengesetz 2025: 30% Bonus Depreciation and Tax Incentives for SMEs

Wachstumschancengesetz 2025: Unlocking €4+ Billion in Tax Incentives

In June 2025, the German government passed the Wachstumschancengesetz (Growth Opportunities Act), representing one of the most significant tax reform packages for SMEs in over a decade. This legislation introduces immediate, substantial tax incentives designed to stimulate business investment, innovation, and economic growth across Germany.

For German SMEs, the Wachstumschancengesetz represents a rare opportunity to substantially reduce tax liability through legitimate depreciation and R&D credits. This guide provides a detailed roadmap for understanding and implementing the key provisions.

1. The 30% Declining-Balance Depreciation (Sonderabschreibung)

What Changed?

The Act introduces a 30% additional declining-balance depreciation on movable business assets (bewegliche Vermoegensgegenstaende des Anlagevermoeegens) in the first year of acquisition. This is available in addition to normal depreciation (Regelabschreibung) and applies retroactively from January 1, 2025.

Qualifying Assets

• Manufacturing equipment and machinery
• Computer hardware and software (purchased, not leased)
• Vehicles (except for personal use)
• Office equipment and fixtures
• IT infrastructure and systems
• Production tools and instruments
• Measurement and testing equipment
• NOT: Land, buildings, financial assets, or intangible assets

Practical Example: Machinery Investment

An SME purchases a €200,000 CNC machine on March 1, 2025, with a 10-year useful life (10% standard depreciation).

2. Expanded Research & Development Tax Credit (Forschungszulage)

New Thresholds and Amounts

The Wachstumschancengesetz significantly expands the R&D tax credit (Forschungszulage). Starting January 1, 2026, the credit basis increases from €6 million to €12 million annually for eligible companies.

Who Qualifies?

• Companies engaging in R&D in eligible fields (IT, biotechnology, engineering, materials science, etc.)
• Direct personnel costs (salaries for R&D employees)
• Subcontracted R&D work to external institutions
• Outsourced R&D work within the EU
• Companies with annual turnover < €1 billion

Calculation Example: R&D Tax Credit

A software SME with 30 employees, 15 of whom work on qualifying R&D projects, calculates their 2026 credit:

• R&D Employee Annual Salaries: €900,000 (15 employees × €60,000 avg)
• Contract R&D Services: €150,000 (external AI consulting)
• Total R&D Basis: €1,050,000
• Credit Rate: 25%
• Gross R&D Credit: €262,500
• Less Wage Tax Bonus (phase-out): €0 (full credit available)
• Net R&D Tax Credit: €262,500

3. Electric Vehicle Incentive: 75% Year-1 Write-Off

EV-Specific Depreciation Rules

To accelerate the transition to electric mobility, the Wachstumschancengesetz allows a 75% depreciation write-off in the first year for qualifying electric vehicles acquired from January 1, 2025, through December 31, 2027.

Qualifying Vehicles

• Battery electric vehicles (BEVs) with €40,000+ list price
• Fuel cell vehicles (FCVs)
• Plug-in hybrid vehicles (PHEVs) used exclusively for business
• Charging infrastructure for electric vehicles

Example: Fleet Electrification

A delivery company invests in 10 Tesla Model 3 Long Range vehicles at €52,000 each in April 2025. Useful life: 8 years (12.5% standard depreciation).

4. Amended §7g Income Tax Act (IAB) Changes

What Is §7g IAB?

§7g of the Income Tax Act (Einkommensteuergesetz) governs depreciation for business assets. The Wachstumschancengesetz modifies these rules to enable faster depreciation on intangible assets (immaterielle Wirtschaftsgüter) such as patents, licenses, and software.

Key Changes

• Software acquired or developed for business use can be depreciated over 3 years (previously 5 years)
• Patents and proprietary licenses can be depreciated on a declining-balance basis
• Business-use software subscriptions are still deductible as operating expenses
• Acquired intellectual property qualifies for accelerated depreciation if documented properly

Who Qualifies for Wachstumschancengesetz Benefits?

Eligibility Criteria

• German-resident businesses (Betriebsstaette in Germany)
• Partnerships, sole proprietorships, and corporations
• Entities with annual turnover < €1 billion (some provisions)
• No restrictions on industry (manufacturing, services, tech, etc.)
• Applicable for acquisitions from January 1, 2025 forward

Who Does NOT Qualify?

• Non-residents or foreign-only entities
• Private individuals (not business owners)
• Passive investment companies without active business
• Agricultural enterprises (separate rules apply)
• Financial institutions (special depreciation rules)

Interaction with Existing Depreciation Methods

Straight-Line vs. Declining-Balance Depreciation

The bonus depreciation under Wachstumschancengesetz works alongside your chosen depreciation method. You must decide: Lineare Abschreibung (straight-line) or Geometrisch-degressive Abschreibung (declining-balance).

Timeline: When Do Provisions Take Effect?

Practical Implementation Roadmap

Step 1: Conduct Asset Inventory (Weeks 1-3)

• List all movable assets acquired in 2025 or planned for acquisition
• Document acquisition dates, costs, and useful lives
• Identify EV investments and charging infrastructure
• Categorize software, patents, and intangible assets
• Separate excluded assets (real estate, financial assets)

Step 2: Calculate Potential Tax Benefits (Weeks 4-5)

• Apply 30% bonus depreciation to qualifying movable assets
• Calculate EV write-off benefits (75% year 1, if applicable)
• Estimate R&D credit eligibility for 2026 (€12M basis)
• Project tax savings at your marginal rate (15-30% range typical)
• Assess impact on estimated tax payments (Vorauszahlungen)

Step 3: Update Accounting Records (Weeks 6-8)

• Revise depreciation schedules in accounting system (DATEV, SevDesk, etc.)
• Document bonus depreciation allocation in asset register (Anlageverzeichnis)
• Establish separate tracking for EV assets and R&D costs
• Update internal cost allocation for R&D credit calculation
• Ensure compliance with accounting standards (HGB/IFRS, if applicable)

Step 4: File Amended Returns (If Needed) - Weeks 9-12

• If assets were acquired early 2025 and 2025 return already filed, file amended return (Einspruch/Feststellungsueberschuss)
• Provide detailed depreciation schedules
• Include documentation of qualifying assets
• Consult with tax advisor (Steuerberater) for complex situations

Step 5: Plan 2026 and Beyond

• Systematically track R&D costs and personnel for €12M credit basis
• Schedule remaining vehicle fleet electrification before Dec 31, 2027
• Coordinate with cash flow planning (depreciation ≠ cash outflow)
• Monitor phase-out of wage tax bonus (scheduled for gradual reduction through 2027)

Common Mistakes to Avoid

• Mixing Bonus Depreciation with Lease Payments: Leased assets don't qualify. Own the asset to claim depreciation.
• Failing to Document R&D Costs: Without detailed documentation (timesheets, project records), R&D credits are at risk in audit.
• Claiming EV Bonus for Personal Use Vehicles: The 75% bonus only applies to business-use EVs. Personal use vehicles are excluded.
• Overlooking §7g IAB Software Benefits: Software developed in-house qualifies if business purpose is documented.
• Not Adjusting Estimated Tax Payments: Lower taxable income means lower estimated tax (Vorauszahlung) requirements—adjust to avoid overpayment.
• Ignoring Useful Life Determinations: Be realistic; overly aggressive useful lives will face scrutiny in audit.

Potential Audit Considerations

Given the generous nature of Wachstumschancengesetz incentives, the German tax authorities (Finanzamt) will likely scrutinize aggressive applications. Prepare for potential audits by maintaining thorough documentation.

Quantifying Your Total Tax Benefit

Sample SME Calculation: Manufacturing Firm

A 40-person manufacturing company in Baden-Württemberg plans 2025 investments and calculates expected tax benefits:

• Equipment Purchases: €400,000 in machinery → 30% Bonus = €120,000 depreciation deduction
• EV Fleet (4 vehicles): €200,000 → 75% Bonus = €150,000 depreciation deduction
• Software Development: €80,000 (in-house R&D) → 3-year depreciation under §7g
• R&D Personnel: 8 employees, €480,000 salaries → R&D credit basis (2026) = €480,000 × 25% = €120,000 credit

Final Recommendations

• Act Quickly on 2025 Investments: All provisions are retroactive to Jan 1, 2025. Accelerating planned purchases into 2025 maximizes benefits.
• Document Everything: Maintain detailed records of acquisition dates, costs, business purpose, and useful life determinations.
• Consult Your Tax Advisor: Rules are complex; a qualified Steuerberater can optimize your situation and defend your position in audit.
• Coordinate with Accounting System: Ensure your accounting software (DATEV, SevDesk, etc.) properly handles bonus depreciation and R&D tracking.
• Plan for 2026-2027: EV incentive expires Dec 31, 2027. Plan your fleet electrification and major capital investments accordingly.
• Monitor Legislative Updates: The Finanzamt will issue official guidance (Finanzbehörden-Erlasse) throughout 2025-2026. Stay informed.

Conclusion

The Wachstumschancengesetz represents a rare and substantial opportunity for German SMEs to reduce tax liability legitimately while investing in growth-critical assets. The combination of 30% bonus depreciation, expanded R&D credits, and EV incentives can generate €50,000-€300,000+ in direct tax savings for mid-sized businesses.

The window for maximizing 2025 benefits is rapidly closing. SMEs should work with their tax advisors immediately to identify qualifying assets, plan strategic investments, and ensure compliant documentation before year-end.
