Tax treatment of R&D expenses in Luxembourg

Part of a comparative survey composed to provide a better understanding of the available alternatives for the tax-efficient structuring of research and development (R&D) activities abroad. The focus is solely on the corporate income tax treatment of R&D expenses (and not on e.g. wage tax or payroll tax regulations). The study is particularly intended to give an update of the most recent rules and regulations in this field, including relevant general tax provisions under corporate income tax law and special tax incentives for R&D expenditure: investment tax credit on gross investment, investment tax credit on additional investment, special depreciation scheme, R&D incentive scheme for small and mediumsized enterprises, and equipment loan provided by the Société Nationale de Crédit et d'Investissement (SNCI).
