Informations
Finding the right chartered accountant in Luxembourg is more than a formality—it’s a strategic choice. At the heart of Europe, bordered by France, Germany, and Belgium, accounting here requires navigating complex tax regulations, multilingualism, and an international business environment. TYLS Luxembourg combines local expertise with a tailored approach for business leaders and investors.
The Grand Duchy stands out for its political stability, attractive tax system, and international openness. Yet this appeal comes with dense and sometimes complex regulations. Corporate taxation, HR management, and accounting compliance all involve numerous and constantly evolving obligations.
This is where TYLS Luxembourg makes a difference—combining local proximity with an international outlook. More than a service provider, the firm is a trusted partner, anticipating risks and delivering tailored, practical solutions for every business.
The term fiduciary in Luxembourg is often associated with accounting expertise. In reality, its role goes far beyond bookkeeping. At TYLS, this role expands into full-spectrum support:
• Company creation and domiciliation: a crucial step for any entrepreneur establishing a presence in Luxembourg.
• Bookkeeping and financial reporting: prepared under local (LuxGAAP) or international standards.
• Management of tax and HR obligations: corporate tax, VAT, payroll, and social security.
• Strategic advice: choice of legal structure, tax optimisation, and guidance on growth or succession.
In short, TYLS Luxembourg is not just a fiduciary—it is a long-term partner for businesses.
At TYLS, the role of a chartered accountant goes far beyond crunching numbers. Accountants are guardians of a company’s financial reliability. Their responsibilities include:
• Preparing annual financial statements
• Designing efficient accounting systems
• Developing forecasts and dashboards
• Coordinating with external parties
Their role is all the more critical as Luxembourg imposes strict financial and compliance standards. With its strong local expertise, TYLS ensures your obligations are met and keeps you fully compliant.
Unlike a fragmented approach, TYLS Advisory Luxembourg brings multiple areas of expertise under one roof:
• Accounting and taxation: to ensure accuracy and optimise the tax burden
• Legal advisory: to secure articles of incorporation, contracts, and strategic decisions
• HR and payroll: to handle social obligations with peace of mind
• Strategic guidance: to support leaders in investment, growth, or succession decisions
This 360° vision allows us to provide bespoke support, adapted to both local and international challenges.
Luxembourg lies at the crossroads of France, Germany, and Belgium. Many executives and employees commute daily across borders. This reality requires in-depth knowledge of tax and social rules in multiple countries.
This is one of TYLS Luxembourg’s greatest strengths: its Franco-Luxembourg expertise and its proven ability to manage cross-border issues.
Some concrete examples:
• How should cross-border employee income be declared?
• Which tax treaty applies to a company with subsidiaries in France and Luxembourg?
• How can VAT be optimised in a cross-border context?
These complex questions demand specific expertise—expertise that TYLS delivers thanks to years of field experience.
Working with an international consulting firm like TYLS is not just for large corporations. Our clients include a wide variety of profiles:
• Business founders: support from drafting articles of incorporation to obtaining a Business Licence
• SMEs and small businesses: outsourcing of accounting, payroll, and legal obligations
• Professionals and independents: tax and HR management tailored to their status
• International groups and investment funds: legal structuring, consolidated reporting, and statutory audits
• Holding companies: profitability management, tax planning, and wealth monitoring
Choosing TYLS Advisory Luxembourg brings clear, measurable benefits:
• Time savings: by outsourcing administrative and compliance tasks
• Legal and tax security: with experts fully up to date on regulatory changes
• Financial optimisation: through proactive management of tax and assets
• Clear insight into profitability: with modern management tools
• Tailor-made support: adapted to both the manager’s profile and the company’s ambitions
What is the cost of a consulting firm like TYLS?
Fees vary depending on company size and scope of work. A start-up founder will not pay the same as an international group. At TYLS, every proposal is transparent and tailored to your needs.
Is TYLS a fiduciary or a consulting firm?
Both. TYLS combines the strengths of a Luxembourg fiduciary specialising in accounting and taxation with the expertise of a multidisciplinary consulting firm able to address strategic challenges. TYLS Luxembourg is also a member of the Luxembourg Institute of Chartered Accountants.
Why choose TYLS over another firm?
Because TYLS brings together multidisciplinary expertise, unique cross-border experience, and close relationships with clients. This combination is what sets us apart.
Conclusion: TYLS, your trusted partner in Luxembourg
In Luxembourg, achieving business success requires strong mastery of accounting, tax, and legal matters. TYLS Advisory Luxembourg plays a key role in securing this journey—turning regulatory constraints into growth opportunities.
Whether you are a founder, SME, or investor, choosing a Luxembourg fiduciary like TYLS and working with experienced professionals means benefiting from reliable support and optimised business management.
