Quick answer
Spain’s Supreme Court (judgment no. 620/2026, 21 May 2026) has struck down the national single registry for short-term rentals — the Registro Único de Arrendamientos (NRUA) created by Royal Decree 1312/2024 — ruling that the State cannot impose a national registry on top of the autonomous regions’ own tourist registers. For owners this means the national NRUA number and its annual declaration no longer apply; your regional tourist licence and the digital single window (Ventanilla Única) still do.
What the Court Ruled
On 21 May 2026 the Spanish Supreme Court issued judgment no. 620/2026, partially upholding a challenge to Royal Decree 1312/2024 of 23 December and annulling the provisions that created the national “Registro Único de Arrendamientos de Corta Duración” (the single short-term-rental registry). The Court did not strike down the whole decree — only the articles establishing the national registry.
The legal ground is competence: the State lacks the constitutional title to create a national registry that superimposes itself on the tourist-rental registries the autonomous communities already operate. In early June 2026 the Court reaffirmed this position in a second ruling (siding with the Región de Murcia, after an earlier case concerning the Generalitat Valenciana), distinguishing the data-coordination duties that flow from EU Regulation 2024/1028 from the creation of a single state registry, which it held contrary to the constitutional division of powers.
What Was the “Fourth Layer”?
Short-term rental compliance in Spain has built up in layers. On top of the regional tourist licence (VFT in Andalucía, ETV in Valencia and the Balearics, VV in the Canaries) and the data-sharing duties channelled through the EU-aligned digital single window, Royal Decree 1312/2024 added a fourth layer: the national Número de Registro Único de Arrendamiento (NRUA), a single state registration number obtained through the Ventanilla Única Digital and mandatory since 1 July 2025.
That fourth layer is precisely what the Supreme Court has now removed. The Court’s reasoning is that the autonomous communities already run their own tourist registries, so a parallel national registry duplicated — and intruded upon — competences that belong to them. The other layers were never the problem; the national registry on top of them was.
What This Means for Your Short-Term Rental
No longer required: the obligation to obtain the national NRUA registration number, and the mandatory annual declaration tied to that single registry, no longer apply following the annulment.
Still required: your regional tourist licence (VFT, ETV, VV and their equivalents) remains fully in force — indeed, the ruling rests on the fact that these regional registries already exist. The Ventanilla Única Digital, the data-transmission obligations of online platforms, and statistical reporting also remain in place. Airbnb, Booking and other portals continue to operate under their EU-derived duties.
In short: the extra national registration layer is gone, but regional licensing and platform-data compliance are unchanged. Owners who were part-way through, or worried about, the national NRUA step can stand down on that specific requirement — while keeping their regional licence current.
