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 paid up. 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?
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.
