Spain Holiday Rental Fines: What 'Muy Grave' Actually Means (2026)

If you run a holiday rental in Spain, sooner or later you will read the words muy grave on an official document and wonder how worried to be. The phrase travels badly: you meet it in tables where the brackets climb to half a million euros, and in a demand your property manager forwards without context.

The underlying problem is that a letter from the Government Delegation and a file from a regional tourism department end up treated as the same thing. With two separate obligations resting on the same flat, it is easy to worry about the wrong fine.

The Spanish offence ladder: leve, grave, muy grave

Spanish administrative law almost never sets a single fine for an offence. Instead it classifies each breach into one of three categories, and attaches a range of amounts to each category. The three terms you will see are:

• Leve (minor). The rung for formal slips: a step taken late, a field badly completed. The bottom of the range.
• Grave (serious). The rung for substantive breach: the obligation that simply was not met, deliberate concealment, obstruction of an inspection.
• Muy grave (very serious). The top rung. Reserved for wilful conduct with real impact, and not every rule provides for it for every conduct. Six-figure fines live here.

The rung is not decided by how serious it feels to you; it is decided by the rule when it types the conduct. In many regional tourism laws repetition does push you from grave to muy grave. Other rules assign a fixed rung to a specific conduct, and then volume does not move the classification at all: the state guest-report regime is of that second kind.

Within each rung there are also degrees (minimum, medium, maximum), and the law requires starting at the minimum. Climbing a degree requires proving a specific aggravating circumstance; a bulky file is not enough.

So muy grave is not a fixed fine. It is a bracket, and where you land inside it depends on conduct.

The two penalty regimes: national and regional

Talking about “the holiday rental fine” in the singular is where most of the confusion starts. There are two fines, they have nothing to do with each other, and they stack.

Two authorities. Two bodies of law. They are independent. You can have your licence perfectly in order and still be fined by the Government Delegation for not filing reports. You can file every report flawlessly and still be fined by your region for never having registered the dwelling. The same flat can attract both at once.

Regime 1: the guest-registration fine (state)

This is the fine for failing to submit the traveller report to SES.HOSPEDAJES, the platform run by the Ministerio del Interior under Real Decreto 933/2021.

The decree itself sets the obligation but not the amounts. For the amounts it points to the general public-safety enforcement regime in Ley Orgánica 4/2015, de 30 de marzo, de protección de la seguridad ciudadana (the “Ley Mordaza”).

This regime never reaches muy grave. Article 8 of RD 933/2021 types only two rungs, and refers exclusively to Articles 36.20 (serious) and 37.9 (minor) of Ley Orgánica 4/2015¹. Article 36.20 is the type a state penalty can reach you through:

“The absence of the registers provided for in this Law for activities with a bearing on public safety, or the omission of mandatory communications.”

Article 35 is never referenced, and that is where very serious infractions live. It contains four closed types: risky assemblies at basic-service infrastructure, weapons and explosives causing very serious harm, events held against a prohibition, and light beams projected at pilots or drivers³. None has anything to do with registers or lodging.

So the brackets under that regime are just two⁴:

The intuitive order is the opposite of the one the decree sets. Not filing the report is serious from the very first omitted report (Article 8.2.b), “the omission of the mandatory communications”). Filing it late is the leve one (Article 8.3.b), “outside the established deadline”)¹. Volume does not move the classification: one unreported stay and fifty are equally serious.

What volume does move is the amount within the rung, and there the law favours a good-faith operator. Article 33.2 splits the serious bracket into three degrees and dictates where you start:

“The commission of an infraction shall entail the imposition of the corresponding fine at the minimum degree.”

For serious infractions that minimum degree is €601 to €10,400 (Article 39.1.b)⁴. The €30,000 is the ceiling of the maximum degree, reserved for facts of particular gravity. Moving from the minimum degree to the medium one requires proving at least one of these four circumstances, and there is no fifth⁵:

1. Recidivism: more than one infraction of the same nature within two years, declared by a decision that is final in administrative proceedings.
2. Violence, threat or intimidation in carrying out the acts.
3. Covering the face with any garment or object to prevent or hinder identification.
4. Using minors, people with disabilities in need of special protection, or people in a situation of vulnerability.

For a paperwork breach our reading is that only the first is realistic: the other three describe conduct that does not appear in a file about unfiled reports.

Sanctioning power over serious and minor infractions sits with the Government Delegates in the autonomous communities (Article 32.1.c)⁶. The Ministro del Interior and the Secretario de Estado de Seguridad only sanction very serious infractions, which this route never reaches. Inspection is carried out by the Dirección General de la Policía and the Guardia Civil.

In Cataluña the sanctioning authority is the Generalitat’s Departament d’Interior and in País Vasco the Basque Government’s Department of Security (Article 32.2), with the Mossos d’Esquadra and the Ertzaintza investigating. (Note: RegistroViajero submits to SES.HOSPEDAJES today; the Cataluña and País Vasco systems are still in development.)

This fine has its own reduction rule, and it beats the general one: the abbreviated procedure in Article 54 of Ley Orgánica 4/2015 cuts the amount by 50% if you pay within fifteen days of being notified of the acuerdo de incoación, the decision opening the file⁷. That deadline is the part that rarely survives the forwarding of the notice, and it is the part that decides whether the reduction exists at all. Payment ends the procedure on the day it is made, with no express decision, means waiving allegations (any already filed are treated as not presented), and leaves an appeal to the contencioso-administrativo courts as the only route left. The abbreviated procedure does not apply to very serious infractions (Article 54.2), which this route never reaches anyway. The most common cases, with the numbers worked out, are in RD 933/2021 penalties.

That 50% belongs to the state public-safety regime and does not carry over to the other fine. A penalty under your region’s tourism law runs through that law’s own procedure, with the general rule of Ley 39/2015 behind it: acknowledging responsibility and paying voluntarily each carry a reduction of at least 20% on the proposed amount, and article 85.3 declares them cumulative⁸. There the total comes off 40%, not 50%, and it also requires withdrawing or waiving any action or appeal in administrative proceedings.

Deadlines count too. Infractions under Ley Orgánica 4/2015 lapse six months after they were committed if minor, one year if serious and two years if very serious (Article 38.1)⁹. And the procedure itself expires once a year has passed from its opening without a decision having been notified (Article 50.1)¹⁰. That expiry does not interrupt the limitation period, so the Administration can open a new file, but only while the infraction has not yet lapsed.

Regime 2: the tourist-licence fine (regional)

This is the fine for marketing a tourist-use dwelling (vivienda de uso turístico, VUT) without being registered in your region’s tourist registry. It is imposed by your autonomous community, under that community’s own tourism law, and this is where muy grave gets genuinely heavy.

Regional tourism laws use the same leve / grave / muy grave ladder, but advertising without a licence does not land on the top rung straight away. In Andalucía, advertising or actually providing the service without having filed the declaración responsable is “clandestine activity”:

“Advertising by any means of dissemination, or the actual provision of tourist services, without having complied with the duty to file the declaración responsable […] shall be considered clandestine activity.”

The listing alone is enough: no guest has to arrive. That clandestine activity is a serious infraction (Article 71.1), fined from €2,001 to €18,000 (Article 78.2). It rises to muy grave, €18,001 to €150,000, only through recidivism (Article 72.10). Reoffending, there, means committing another infraction of the same class within one year of notification of a penalty that is final in administrative proceedings (Article 79.2).

In Illes Balears the line is drawn by the dwelling, not by repetition. Marketing without having filed the declaración responsable is a serious infraction, fined from €30,001 to €50,000 (Articles 119.g) and 123.2). It jumps to very serious when the dwelling did not meet the conditions to be registered at all:

“Advertising, contracting or marketing tourist stays in residential-use dwellings whose typology does not permit the filing of the declaración responsable de inicio de actividad turística, or dwellings located in zones not suitable for the marketing of tourist stays in residential dwellings, or where the tourist places have not been acquired.”

There the fine runs from €50,001 to €500,000 (Article 123.3). What decides the rung is not how many guests you hosted, it is whether the dwelling met the conditions to be registered.

The very-serious brackets reach six figures in several communities. Seven examples, with the law that sets each one:

The scale moves: Illes Balears raised its own with Decreto-ley 4/2025, of 11 April 2025. Confirm the current amount and exact classification against your community’s law before relying on any single number. The full table, covering the 17 communities and the two autonomous cities, is in renting without a tourist licence in Spain.

A bracket is what the law allows, not what actually gets imposed. The real figures for each region that publishes them, from inspections to the amounts fined, are in tourist rental inspections and fines in Spain by region.

Which licence you need, the registry name, and where to apply all vary by region: in most it is a declaración responsable, and that is where the number you have to publish in every listing comes from. The procedure for each community is in the tourist licence in Spain by region guide.

”Muy grave” means different money depending on the regime

Put the two side by side, with the state amounts from Article 39.1 of Ley Orgánica 4/2015⁴ and the Balearic ones from article 123 of Ley 8/2012¹², and the same label behaves very differently:

That empty cell is the practical difference between the two regimes. If you read muy grave on a document, it cannot come from the guest report: the state ceiling for failing to report is the €30,000 of the serious infraction, and in practice the €601 to €10,400 minimum degree.

So when you see muy grave on a notice, the first question is not “how much” but which authority sent it. A letter from the Government Delegation about SES.HOSPEDAJES is the state regime, and there the classification can only be minor or serious. A letter from your autonomous community’s tourism department is the licence regime, and it is the only one of the two where muy grave is possible. They will not arrive on the same letterhead, and they are resolved through separate procedures.

Additional licence penalties: closure and repeat offences

The regional licence regime does not stop at the fine, and what comes with it often hurts more:

• Listing removal. Regulation (EU) 2024/1028, applicable since 20 May 2026, requires platforms to obtain the registration number before allowing the offer and to display it in the listing, wherever a registration procedure applies. And it requires Member States to make sure national law allows authorities to order platforms to remove listings with no number or with an invalid one¹⁸. No listing, no bookings, regardless of any fine.
• Suspension and closure. In Andalucía a serious infraction can carry temporary closure of the establishment for under six months, and a very serious one from six months to three years (Article 78)¹¹. In Illes Balears the accessory penalties for very serious infractions include loss of the effects of the declaración responsable and permanent closure (Article 123.3)¹².
• Cancellation of the registration. Andalucía can order permanent closure and cancellation in the Registro de Turismo de Andalucía. That takes two or more penalties for very serious infractions within three consecutive years, by a final decision, plus conduct that causes serious harm to the community’s tourism interests (Article 78.3)¹¹.

The state guest-registration regime cannot be classified muy grave, but it is not money only either. Article 39.2 of Ley Orgánica 4/2015 allows a serious-infraction fine to be accompanied by two accessory penalties: suspension of licences, authorisations or permits, and closure of the premises for up to six months. Both are confined to the matters governed by Chapter IV of the law⁴. And it is Article 25, inside that same chapter, that imposes the documentary-register obligations on lodging activities¹⁹.

On paper, then, temporary closure is not outside the state scale. What is outside it is the muy grave rung.

How to avoid both fines: licence in order, reports on time

Two obligations, two regimes, and the same principle for each: do the thing, and keep proof you did it.

1. The licence. Register the dwelling with your autonomous community before you advertise it, because in Andalucía and Illes Balears the listing is by itself the punishable conduct. Publish the number it assigns in every listing, and check it again whenever you move platforms.
2. The guest report. The obligation returns with every single guest. Collect their data and file it to SES.HOSPEDAJES within the deadline, every time, and keep an auditable record.

Doing the second by hand at volume is where a late report (leve) quietly becomes a report that never goes out at all (grave).

That second obligation is the one RegistroViajero automates: a phone-based digital check-in for guests in 9 languages, real-time validation, and automatic submission to SES.HOSPEDAJES, with an auditable log of every report.

That log is precisely what keeps you out of the serious rung: proof that the report went out, and went out on time. We do not issue tourist licences and we do not replace your community, the regional regime is yours to comply with, but the daily state obligation is the one we take off your desk.

Complying doesn’t have to be work: here’s how RegistroViajero handles the guest report.
