Fines for not registering guests: what the law says
This isn't meant to scare you, just to inform you: since 2 December 2024, registering and reporting your guests to SES Hospedajes is mandatory, not optional, and the law sets out specific sanctions for not doing it. Here are the official sources, with no invented figures.
The obligation: Royal Decree 933/2021
Royal Decree 933/2021, of 26 October, sets out the record-keeping and reporting obligations for anyone running a hospitality activity. It entered into force on 2 January 2023, and compliance — including reporting through SES Hospedajes — has been enforceable since 2 December 2024.

The fines don't come from RD 933/2021 itself, but from Ley Orgánica 4/2015 on the protection of public safety, which classifies violations and sets their amounts:
Minor infraction — €100 to €600
For irregularities in completing the required records, including late communications (art. 37.9 LO 4/2015).
Serious infraction — €601 to €30,000
For lacking the required records entirely, or completely omitting the mandatory communications (art. 36.20 LO 4/2015).
The amounts are set out in art. 39.1 of the same law. Each case is assessed on its own circumstances — this isn't legal advice, and the exact figure for a specific case depends on the investigating authority.

Andalucía's Decreto 31/2024, besides requiring the tourism-register (RTA) code in all advertising for a tourist rental property, writes the 24-hour SES reporting duty into regional law too — which lets regional tourism inspectors act on a failure, not just the police.

Frequently asked questions
Since when is compliance with RD 933/2021 mandatory?
The Royal Decree entered into force on 2 January 2023, but actual enforcement of reporting through SES Hospedajes has applied since 2 December 2024.
Are fines actually being issued?
Yes — the Ministry of the Interior has opened sanction proceedings since 2025, mainly against companies. The obligation is real and active, not just theoretical.
Is the fine always up to €30,000?
Not necessarily — it depends on whether the infraction is classified as minor (€100–600) or serious (€601–30,000), based on the case's circumstances. The law also has a very-serious tier for other public-safety matters, not specifically this obligation.
How do I avoid a fine without spending time on it every day?
By automating check-in and filing, so no booking slips through because of a missed reminder or a bad time to log into the portal. That's exactly what Checkinea does.
