Start with the distinction that causes most confusion about SES.Hospedajes. There are two separate 24-hour reporting deadlines, not one.
The first clock starts when you make or cancel a booking. The second starts when the guest arrives. Each clock applies to different information, and neither replaces the other.
That is what Article 6.3 of Royal Decree 933/2021 says. The Ministry of the Interior repeats the same rule in its official SES.Hospedajes FAQ.
Clock one starts when the booking is made
Report the booking or accommodation contract within 24 hours of making it. Report it immediately if you can — the law describes 24 hours as the outer limit, not the target.
This first report concerns the booking and transaction. It includes information such as:
- Reference — the booking or contract reference
- Dates — the relevant dates for the stay
- Property — the accommodation connected with the booking
- Payment — the payment method and related transaction information
It is not the same report as the guest-identification submission. The booking report does not ask you to submit each traveller's passport details simply because the booking has been made. The traveller data belongs to the second stage, linked to the start of the stay. The information categories appear in Annex I of Royal Decree 933/2021.
Cancellation starts the clock again
Report a cancellation within 24 hours of the cancellation.
The wording of Article 6.3 includes the reservation or contract and, where applicable, its cancellation. A booking that was previously reported does not disappear from your compliance records merely because the guest later cancels it.
Record the cancellation as its own event. Apply the same rule to relevant changes where the system requires an updated communication.
Clock two starts when the guest arrives
Report the guests within 24 hours of the start of the contracted services. For an accommodation booking, that normally means the guest's actual arrival or check-in.
This is the report that contains traveller information such as:
- Identity document — the document type and number
- Date of birth — for each traveller
- Nationality — as recorded from the identity document
- Residence details — where required by the applicable data fields
- Arrival and departure — the dates and times connected with the stay
Submit this report no later than 24 hours after the stay begins. If the guest checks in at 18:00 on Friday, the maximum deadline runs to 18:00 on Saturday.
Do not treat the guest report as an alternative to the booking report. You must complete both communications when both events occur.
Read the word "respectively" carefully
The law says communications must be made within 24 hours from the two moments listed — the booking or cancellation, and the start of the contracted services — respectively.
That word matters. It links each obligation to its own event.
Do not choose whether to report at booking or arrival. Report the booking when it is made, then report the guests when the stay begins. If the booking is cancelled, report that cancellation from the moment it occurs.
The Ministry's published guidance follows the same two-stage structure.
Register the property before either clock begins
Complete the property and business registration before you start letting.
Article 6.1 and 6.2 require the obliged provider to communicate the activity and accommodation details before the activity begins. The communication should take place within ten days of completing the administrative formalities required for the activity — and, in every case, before you begin operating.
Treat this as a one-off setup step, subject to updating the information if relevant details change. It is not a third 24-hour report that begins with your first booking.
You will normally need an accepted Spanish electronic identification method to access the digital procedure. For many non-resident owners, obtaining the required digital identity is the hardest practical part of the process. See the explanation of Spanish digital certificates before you begin.
Check whether the obligation applies to you
Apply the rule if you provide paid accommodation in Spain, whether you do so professionally or occasionally.
The decree covers accommodation provided for a price, payment or other compensation. It applies regardless of the size of the property, the number of bedrooms or how often you let it. A person who lets a property for one week each year through Airbnb or Booking.com does not receive an automatic occasional-host exemption under this rule. See Articles 1, 2 and 3 of the decree.
Check the regional channel if the property is in Catalonia or the Basque Country.
- Most of Spain — use SES.Hospedajes for the applicable communications.
- Catalonia — use the Mossos d'Esquadra traveller registration system.
- Basque Country — follow the applicable Ertzaintza procedure rather than assuming that the national process is the correct channel.
The reporting principle remains time-sensitive, but the operating system can differ by territory. Confirm the current regional procedure before accepting guests.
Separate the three registrations people mix up
Keep these obligations separate. They have different purposes and may involve different authorities.
- SES.Hospedajes — a Ministry of the Interior system for reporting accommodation activity, bookings and travellers for public-security purposes.
- Tourist licence or regional registration — a requirement set by the autonomous community or other competent regional authority. It concerns whether and how the property may operate as tourist accommodation.
- The national rental registry — the central government registration scheme created for short-term rentals was cancelled by the Supreme Court in May 2026. That decision did not cancel SES.Hospedajes, and it did not remove regional tourist licences or registrations. Reuters reported the judgment.
Do not assume that the cancellation of one national rental scheme removed the separate public-security duty to report guests.
Understand the fines without the scare stories
Apply the correct category to the correct failure.
- Late filing — a communication made outside the legal deadline is a minor offence, with a fine of €100 to €600.
- No filing — omitting a mandatory communication is a serious offence, with a fine of €601 to €30,000.
- Missing records — the absence of required records is also identified as a serious offence under Article 8 of the decree.
The relevant amounts come from the Organic Law on Citizen Security. Claims of €100,000 or more for a late or missing SES.Hospedajes communication are wrong as a description of this specific regime. Other tourism, tax or licensing issues may have separate consequences, but they should not be confused with these figures.
The infringement limitation periods are also shorter than many online articles suggest.
- Minor offence — six months
- Serious offence — one year
Keep those periods separate from the data-retention rule. The limitation period concerns enforcement of the offence. It does not reduce the record-keeping obligation.
Keep the records for three years where required
Retain the required records for three years from the end of the contracted service.
Article 5.3 of Royal Decree 933/2021 sets that period. The decree also contains an exception for providers carrying out accommodation activity on a non-professional basis. Those providers remain subject to the communication duties, but the specific registration and conservation obligations in Article 5 do not apply to them.
If you operate commercially or manage accommodation professionally, build the three-year retention period into your normal record-keeping process.
Follow the process in this order
Use this sequence for a new accommodation.
- Obtain accepted Spanish digital identification — complete the electronic identification step before you need to submit an urgent booking.
- Register the business and property — communicate the activity and accommodation details before you begin letting.
- Report each booking — submit the booking or contract information immediately and no later than 24 hours after it is made.
- Report each cancellation — submit the cancellation immediately and no later than 24 hours after it occurs.
- Collect and report the guests — submit the traveller information within 24 hours of the stay beginning.
- Retain the records — keep the required records for three years unless the non-professional exception applies.
Do not wait until check-in to deal with every part of the process. By then, the first clock may already have expired.
Do not let an OTA workflow decide your legal process
Major online travel agencies often try to keep compliance inside their own systems. That can restrict independent compliance providers, prevent the use of fixed registration links and make a simple legal obligation harder to manage.
The law sets the information and deadlines. It does not say that you must use a particular OTA's preferred compliance tool. A fixed link can give each booking a stable route to guest registration, while free tools such as Guest-Flow can help owners organise the process without depending entirely on an OTA's changing workflow. See the practical guest registration guidance for the difference between collecting guest details and submitting them to the authorities.
If an OTA or government system is unavailable, assume that the clock continues. Article 6 does not create an exception that pauses the deadline during a technical outage. Save evidence of the outage, record what you attempted and submit the communication as soon as the system becomes available — but do not assume that the missed time is automatically excused.
Use a reference that answers the question you actually have
SES.Hospedajes is difficult to understand because short explanations often merge separate duties into one. The result is contradictory advice about bookings, check-in, cancellations, licences, fines and the systems used in different regions.
That is why seshospedajes.com exists.
The site launches with 142 questions and counting. Each answer is checked against the legislation and linked to the relevant legal or official source. It is designed as a reference, not a sales page.
If your question is not there, send it to the site. The team researches each question against the legislation, emails you the answer and publishes it for the next person who needs the same clarification. You can also join the site's free Facebook group to compare practical questions with other owners and managers.
Remember the central rule — two events create two clocks. Report the booking or cancellation within 24 hours. Report the guests within 24 hours of arrival. Register the property before you start letting, and do not confuse SES.Hospedajes with a regional tourist licence or a cancelled national rental registry.
Once those distinctions are clear, the process is much easier to organise.
