Failing to report your guests’ data has financial consequences. Here is where the penalties come from and how to remove the risk.
What RD 933/2021 actually requires
Royal Decree 933/2021 requires accommodation establishments and car-rental companies to register their customers and report their data to the authorities. That report is filed through SES Hospedajes within a maximum of 24 hours.
The decree defines the obligation and, in its Article 8, classifies breaches as minor or serious infractions. For the amounts and the procedure, it refers to Organic Law 4/2015 on the Protection of Citizen Security.
Where the fines come from: the Citizen Security Law
RD 933/2021 classifies the infractions, but the size of the fines and the sanctioning procedure are governed by Chapter V of Organic Law 4/2015 on the Protection of Citizen Security.
In other words: the decree defines what you must do and how each breach is classified; Organic Law 4/2015 sets how much it costs.
Which breaches are penalised
There is no single type of breach. An inspection can penalise very different situations:
- ✓Not registering guests or reporting their data at all.
- ✓Filing the traveller report after the 24-hour deadline.
- ✓Reporting incomplete or inaccurate data, or data without the traveller’s signature.
- ✓Failing to keep the information for the period required by the regulation.
How much the fines can cost
Breaches of the traveller-registration rules fall into two levels. Minor infractions —such as filing the report late, or smaller irregularities— carry fines of €100 to €600. Serious infractions —such as not keeping the register or not reporting the data— range from €601 to €30,000.
The exact amount depends on how the infraction is classified, whether it is repeated, and the circumstances of the case. For your particular situation, consult the official text of RD 933/2021 and Organic Law 4/2015, or a legal adviser.
How to remove the risk entirely
Most penalties arrive not through bad faith but through oversights: a report filed late, a field copied wrong, an arrival left unregistered on a hectic day.
BookCheckin removes that margin for error: it collects the guest’s data before arrival, validates it, and reports it to SES Hospedajes within the deadline automatically, storing the receipt for every submission. Compliance no longer depends on someone remembering.
