Eight criteria that separate simple bookkeeping from genuine financial infrastructure. Use them to assess any firm, ours included.
The full checklist, seven criteria in the order we suggest checking them, is on our how to choose your fiduciary in Luxembourg page.
Direct answers to Luxembourg's key questions.
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.
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%.
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).
What capital is required to form a SARL?
The minimum capital of a SARL is EUR 12,000, fully subscribed; since 2 June 2026, the matching cash may be paid up within twelve months if the articles so provide. The SARL-S can start between EUR 1 and EUR 12,000, and the SA requires EUR 30,000.
When must annual accounts be filed?
Annual accounts must be approved at a general meeting within six months of the financial year-end, then validated on the eCDF platform, then filed with the RCS, in principle within the month following approval.
Does a Luxembourg holding need substance?
Substance requirements depend on the holding's functions, transactions and tax position. Adequate Luxembourg governance, decision-making and documentation matter most where the participation exemption or treaty benefits are relied upon: they are what allows economic reality to be shown against anti-abuse rules (art. 166 (2bis) LIR, § 6 StAnpG).

What would your Luxembourg back office cost?
A SOPARFI is a company used as a holding vehicle, usually incorporated as a SARL or SA.
Indicative recurring budget based on the assumptions below. Annual recapitulative VAT returns, EC Sales Lists, one-off fees and disbursements are excluded; this result does not reproduce the full scope of packages in our published fee schedule.
Payroll includes annual CCSS and RTS communications (EUR 150 excl. VAT each), amortised over twelve months. File opening (EUR 200 excl. VAT, one-off) is not included in this recurring estimate.
Estimate assumptions and scope
The bookkeeping workload model starts at EUR 250 excl. VAT per month (EUR 250 for a passive holding), with an indicative EUR 2.20 adjustment per monthly invoice. The upper bound adds a 40% modelling allowance. These assumptions are not a billing tariff. Your quote specifies the services included in your package.
The EUR 250 company reference, excluding passive holdings, assumes the EUR 10 signature discount: the engagement letter and SEPA mandate must be signed within 48 working hours of receiving the quote. The reference package without this discount is EUR 260 excl. VAT per month.
VAT: EUR 220 excl. VAT per monthly return, EUR 230 per quarterly return or EUR 100 per simplified annual return, converted to a monthly equivalent. The annual recapitulative return (EUR 500 excl. VAT), EC Sales Lists and one-off work are excluded from the calculation; any inclusion in a package is specified in the quote.
Indicative, non-binding estimate. VAT depends on the client situation; disbursements and filing fees are extra. Registered-office services are provided by an attorney at law (List I). Firm quote after scoping.

Frequent questions, precise answers.
Are you an accounting firm authorised by the Ministry of the Economy?
Yes. Financial Services Luxembourg is an accountant holding a business licence issued by the Ministry of the Economy: authorisations 10077274/0 (accounting, 2017) and 10077274/2 (ancillary activities, 2020). The firm is subject to AED supervision for AML/CFT purposes. Both authorisations can be verified on guichet.public.lu.
Do you work with non-resident clients?
Yes. We serve international entrepreneurs and investors in French and English, and by email in seven other languages, with experience across 28 nationalities and a command of substance and tax-treaty matters.
Can you take over existing bookkeeping?
Yes. We organise the migration from your current firm: retrieval of balances, takeover of entries, continuity of filings, with no service interruption.
Do you provide domiciliation and a local director?
Domiciliation is provided by an attorney at law (avocat à la Cour) registered on List I of the Luxembourg Bar, who contracts directly with you; we coordinate the set-up. Where substance requires it, we provide an independent director with genuine powers and skills.
