Holdings, PE, SPV and sponsor-led structures
Luxembourg setup, domiciliation and execution for multi-entity files
Acquisition vehicles, HoldCos and sponsor-led structures require local coordination, governance discipline and clean year-end follow-through from the start.

Frequently asked questions
Accounting, tax and company formation in Luxembourg
01 What is the cost of a chartered accountant in Luxembourg in 2026?
Chartered accountant fees are not regulated. They vary by firm and by the scope of each engagement. At Fiduciaire Expert, we chose a clear and transparent accounting and tax support. Contact us to discuss your situation.
02 How long does it take to create a SARL in Luxembourg?
Timing is a real concern for entrepreneurs and directors. Some steps can be completed quickly (drafting the articles of association, applying for a business permit, etc.), but the overall timeframe mainly depends on notary availability and banking formalities.
03 Why choose a chartered accountant in Luxembourg?
Accounting in Luxembourg requires precision and strict compliance. A single error in the annual accounts can have consequences for years. Fiduciaire Expert secures your accounting, VAT, tax filings and CCSS obligations.
04 What is the difference between an accountant and a chartered accountant in Luxembourg?
An accountant handles bookkeeping and the preparation of annual accounts and tax returns. A chartered accountant has a broader, company-wide view and can intervene more widely: strategic advice, review and certification, legal and tax support.
05 What accounting and tax obligations for a company in Luxembourg?
Every company must keep accounts compliant with Luxembourg law, file annual accounts and publish them with the LBR. Businesses must also meet VAT deadlines, corporate income tax (CIT), municipal business tax (MBT) and net wealth tax (NWT) obligations.
