FAQ

Frequently asked questions

What is an intragroup financing company?

A Luxembourg company lending to related entities. Its remuneration must be arm's length, justified by real substance and risk-bearing capital, in line with the circular of 27 December 2016.

Is interest always deductible?

No. Art. 168bis LIR, from ATAD, caps the deduction of exceeding borrowing costs (in principle 30% of tax EBITDA or EUR 3 million, whichever is higher), with exceptions. We scope your situation.

What substance for a financing company?

Decision-making bodies in Luxembourg, real competence, capital suited to the risk borne and local accounting. We calibrate substance with you.

Must intragroup loans be documented?

Yes: loan agreements, arm's length analysis and transfer pricing documentation are essential to defend the tax treatment.
