Common Questions
The Start-Up Tax Credit in Luxembourg provides qualifying companies with significant tax benefits that may include reduced corporate income tax rates, tax holidays during initial operating years, exemptions from customs duties on imported equipment, and enhanced deductions for qualifying investments. The specific benefits depend on the company's sector, investment size, location, and employment commitments. Companies must typically apply and receive approval before commencing their investment to ensure eligibility. The incentives are designed to attract productive investment, stimulate economic growth, and encourage companies to establish or expand operations within the jurisdiction.
Companies apply through the designated government agency in Luxembourg by submitting detailed documentation including the business registration certificate, investment plan with projected expenditures and timelines, employment projections, and a description of qualifying activities. The review process evaluates whether the proposed investment meets the program's sector, size, and activity requirements. Processing times vary but typically range from several weeks to a few months. Companies should apply well in advance of their planned investment to secure approval. Maintaining compliance with reporting requirements after approval is essential to retain the incentive benefits throughout the designated period.
Investors must acquire shares in qualifying Luxembourg-registered startups meeting criteria regarding company age, headcount, and turnover. The investment must be direct equity subscription with minimum retention periods. Resident natural persons file claims through annual tax declarations with the credit applied against personal income tax liabilities, supported by share certificates and compliance attestations.
Luxembourg's credit complements its favorable capital gains treatment and wealth management infrastructure. Comparable UK SEIS/EIS, French IR-PME, and Belgian Tax Shelter schemes offer varying holdback requirements and claim ceilings. Luxembourg's distinctive advantage lies in combining the investor credit with its broader international holding company regime, creating layered fiscal benefits for sophisticated angel investors.
