Five more companies join Luxembourg's deductible-donation SIS list

Cash donations to five more Luxembourg companies qualify as tax-deductible liberalities for donors. CO-OP 01 S.I.S., Haff Wandelbléi S.à.r.l.-S S.I.S., Proliving SARL S.I.S., RESI (Real Estate with Societal Impact) S.I.S. and Tangna Impact S.I.S. each appear on the Administration des contributions directes register of sociétés d'impact sociétal (SIS) approved by the Ministère du Travail (MTE), with 2026 shown as the relevant year. The year shown next to an organisation on the Administration's donation registers is the first tax year for which donations to it are fiscally deductible.

Deductibility is narrow in two ways. It covers only donations in cash (dons en espèces) to duly approved SIS companiesPublic, and only where the company's share capital consists 100% of impact shares (parts d'impact)Public. Approval follows article 14 of the amended law of 12 December 2016 amending article 112(1) L.I.R., and a company seeking the status must apply for ministerial approval to the Ministère du Travail. A donor relying on the relief therefore needs two facts to coincide: the recipient holds SIS approval, and the 100% impact-share condition is met.

The general quantitative limits for deductible liberalities continue to apply. The annual total of liberalities must reach at least 120 euros to be deductible as special expensesPublic. The annual deduction for liberalities and donations cannot exceed 20% of total net incomePublic, nor 1,000,000 eurosPublic. Amounts above those limits may be carried forward to the two subsequent tax years under the same conditions and limitsPublic. The same conditions and limits apply for the purposes of municipal business tax.

For advisers, the practical consequence is that cash donations made to any of the five companies from the 2026 tax year can now be positioned within the deductible-donations framework, subject to the thresholds and the carry-forward rulePublic. Before signing off, verify the recipient's current entry on the register: several listed SIS companies carry notes stating that deductibility of donations is no longer accepted from a stated date, so a historic listing alone does not prove current eligibility. Non-resident donors can claim the deduction only through assessment (imposition par voie d'assiette)Public, subject to article 157ter L.I.R. or the relevant treaty provision.

Legal basis: article 112, paragraph 1, number 5 L.I.R., as inserted by article 14 of the loi du 12 décembre 2016 portant création des sociétés d'impact sociétal.
