VAT · Corporate tax · Luxembourg

Direct answers to Luxembourg's key questions.

Q&A
What is the VAT rate in Luxembourg in 2026?

As of 1 January 2026, the standard VAT rate is 17%, with reduced rates of 14%, 8% and a super-reduced rate of 3% (source AED). It is the lowest standard rate in the European Union.

Q&A
What is the corporate tax rate in Luxembourg?

The aggregate corporate tax rate in Luxembourg City is about 23.87% as of 1 January 2026: corporate income tax of 16%, increased by a 7% employment-fund surcharge, plus the municipal business tax of 6.75%.

Q&A
What is a SOPARFI?

A SOPARFI is a fully taxable Luxembourg company used to hold participations and structure international investments, benefiting from the participation exemption (art. 166 LIR).

Q&A
What capital is required to form a SARL?

The minimum capital of a SARL is EUR 12,000, fully paid up. The SARL-S can start between EUR 1 and EUR 12,000, and the SA requires EUR 30,000.

Q&A
When must annual accounts be filed?

Annual accounts must be approved at a general meeting within six months of the financial year-end, then filed with the RCS via the eCDF platform, in principle within the month following approval.

Q&A
Does a Luxembourg holding need substance?

Yes. Since the ATAD directives, a holding must have real substance: effective registered office, decision-making bodies in Luxembourg and documented governance, failing which tax benefits may be challenged.

Trust asymmetries, 11

What worries you before changing firm.

Nine legitimate concerns, nine precise answers. Because security is a deliverable.

QCan my former accountant block the migration?
RNo. You remain the owner of your accounting. We make a structured handover request, track deadlines, and take over in parallel to guarantee zero break in VAT, payroll or close.
QWhat if an ACD or AED audit lands during the transition?
RWe rebuild the defence file in under 5 business days via an internal protocol. Our teams have handled over 40 ACD and AED audits over 18 years, with no material incident.
QWill you really respect confidentiality?
RNDA signed before any document exchange. Compartmentalised internal access, European hosting, full traceability. The standard our family-office clients require applies to all files.
QIs the stated formation timeline realistic?
R4 to 8 weeks depending on the legal form and bank responsiveness. A firm timeline, shared from day 0. If the business license drags beyond 30 days, we escalate the file.
QMy file is complex, will you understand it?
RMulti-jurisdiction holdings, family offices, fund structures, cross-border M&A, IP Box, transfer pricing. Complexity is our core business. We coordinate foreign lawyers, banks and tax advisers as standard.
QHow long before a bank account?
RUsually 2 to 6 weeks. Our pre-structured KYC file (substance, UBO, source of funds, business plan) speeds up acceptance by local banks.
QWill the fees drift during the year?
RFixed monthly fee, reviewed once a year with 60 days' notice. No hourly billing except exceptional mandates approved in writing before execution.
QWill you coordinate with my other advisers?
RYes. Business lawyers, foreign tax advisers, private banks, notaries, fund depositaries. We take on the operational coordination to avoid fragmentation.
QWhat happens if I leave FSL one day?
RFull file return within 30 days, in a usable format, with no exit fees. Our clients stay 8 years on average, but leaving is a right, never a fight.

FAQ

Frequently asked questions

What services do you offer in Luxembourg?
Company formation, bookkeeping and annual accounts, tax and VAT, payroll/CCSS, consolidation, directorship and substance, compliance (AML/KYC, DAC6, CRS/FATCA), holding and fund structuring, and outsourced CFO, with a single point of contact.
How long does it take to set up a company?
Usually 2 to 3 weeks, at most one month, once the file is complete (KYC, capital deposit, notarial deed, RCS and RBE registration). A SARL-S can be faster.
When must annual accounts be filed?
Accounts must be approved by the general meeting within 6 months of the financial year-end, then filed with the RCS within one month of approval, i.e. within 7 months of the closing date. Late filing triggers penalties.
Is an approved statutory auditor mandatory?
It becomes mandatory when the company exceeds, over two consecutive years, two of these three thresholds: balance-sheet total EUR 4.4m, net turnover EUR 8.8m, 50 employees on average. Below that, a commissaire may suffice depending on the legal form.
What is an accountant's hourly rate in Luxembourg?
Indicatively, EUR 70-150/h for standard accounting (bookkeeping, payroll, filings) and EUR 150-300/h for specialised advisory (audit, tax strategy, M&A). We also offer fixed monthly packages.
Do I need a physical office in Luxembourg?
The company must have a registered office in Luxembourg. We provide a compliant domiciliation address and, where needed, substance (governance, local director).
Which languages do you work in?
Mainly French and English. The firm serves an international client base (entrepreneurs, holdings, investors, funds, family offices).
