The statutory deadline for reporting an employee’s deregistration or a change to their details to Spain’s Social Security system has increased from three to six calendar days. The extension, approved by Royal Decree 643/2026, takes effect on 1 August 2026 and applies throughout Spain, including the Canary Islands.
The change gives employers more administrative room, but it should not be read as an invitation to wait until day six. The actual date of termination or change must still be reported accurately, and late handling can complicate payroll, contributions, employer certificates and settlements.
In brief: from 1 August 2026, applications to deregister employees and notifications of changes to their details must be submitted within the six calendar days following the termination or the event that caused the change. The previous deadline was three calendar days.
What exactly changes for Social Security deregistrations?
Royal Decree 643/2026 amends Article 32.3.2 of the General Regulation on company registration and employee affiliation, registration, deregistration and data changes in the Social Security system. The new wording doubles the reporting window from three to six calendar days.
The rule covers two types of procedure:
- applications to deregister employees;
- notifications of data changes when a circumstance that must be recorded by the General Treasury of Social Security changes.
The reform concerns the submission deadline. It does not alter the day on which employment actually ends, nor does it extend the employment relationship by six days. If employment ends on a Friday, for example, Friday remains the effective termination date; only the time available to report it is extended.
This distinction matters to employers. An incorrect date can affect contributions, payroll, the employer certificate or a future review. Specialist employment and payroll advice can help incorporate the new deadline while keeping effective dates under control.
How are the six calendar days counted?
The regulation expressly refers to calendar days. Saturdays, Sundays and public holidays therefore count. Employers should not automatically apply the business-day method used in other administrative procedures.
If the termination or change occurs before a weekend or public holiday, every consecutive day must be counted. As a matter of prudence, it remains advisable to report as close as possible to the underlying event and to reserve the additional margin for justified incidents.
The extension does not, by itself, amend other employment or Social Security deadlines. Employee registrations, document submissions, contribution obligations and procedures before the SEPE retain their own rules. Before applying the new window to any other procedure, its specific legislation must be checked.
When does the new deadline start to apply?
Royal Decree 643/2026 was published in the Spanish Official State Gazette on 30 July 2026 and enters into force on 1 August 2026.
To identify the applicable rules, employers must consider when the termination or data change occurs and the date on which the regulation enters into force. Transitional situations and already-open incidents should be reviewed individually before the movement is submitted.
What additional CNO occupation-code obligation does the reform introduce?
The reform adds a separate requirement that may involve substantial preparatory work. During the six months following its entry into force, employers must report to the General Treasury of Social Security the occupational code—sole or principal—of employees registered under any of their contribution account codes, in accordance with the current National Classification of Occupations (CNO).
The notification is required only where that information has not already been reported. Before submitting data in bulk, it is sensible to:
- check which employees already have an occupation code on record;
- identify the actual and principal occupation attached to each role;
- compare the selected code with the current National Classification of Occupations;
- document the reasoning where a role combines several duties;
- retain evidence of the notification made.
The code should not be chosen merely from an internal job title. It must represent the work actually performed. The decree explains that the information will be used, among other purposes, for studies concerning possible reductions in retirement age for exceptionally arduous, toxic, dangerous or unhealthy work.
What changes apply to Social Security debt deferrals?
The royal decree also amends the General Regulation on Social Security Collection. These provisions are separate from the new deregistration deadline and should be assessed independently.
Contributions that cannot be deferred
The regulation confirms that the following remain non-deferrable:
- the employee contribution paid by employed workers or equivalent persons;
- all contributions for occupational accidents and diseases, for both employed and self-employed workers.
If a deferral is granted and these contributions have not already been paid, they must be paid within one month of notification of the decision.
Thresholds for exemption from providing security
No security is required where the deferrable debt is no more than EUR 150,000. Nor is security required where it is below EUR 250,000, provided that at least one third is paid within ten days of notification of the approval and the balance during the following two years.
These thresholds do not make approval automatic. The Treasury must still verify that the statutory conditions are met and issue a decision.
Possible automated processing
The text authorises the Directorate-General of the General Treasury of Social Security to establish, through a later resolution, automated processing and approval for certain deferrals that do not require security.
The distinction is important: the royal decree creates the legal authority, but automated processing should not be treated as generally available from 1 August. It will depend on a resolution setting out the relevant conditions, requirements and scope.
As a general rule, a deferral may also be refused where the deferrable debt does not exceed the monthly statutory minimum wage in force at the time of application. This circumstance will not apply to files that are ultimately processed and granted automatically under the new provision.
What should employers and HR teams review now?
An orderly adaptation does not require the entire employment workflow to be redesigned, but it does require a review of the points where the new deadline could cause confusion. A practical checklist is:
- update internal procedures that still refer to three calendar days;
- inform HR, administration and managers who report terminations or changes;
- maintain a reliable record of the actual date of each termination or change;
- configure reminders that count calendar days, including weekends and public holidays;
- review CNO codes already reported and prepare any missing records;
- keep deregistration and data-change documents separate from deferral files;
- retain filing receipts and review Treasury responses;
- coordinate the change with the person or business adviser responsible for employment obligations.
The extension eases operational pressure, but the best practice remains to transmit the information promptly. Routinely waiting until the final day increases the risk of errors, particularly when documents are missing or the system reports an incident.
Does the rule also apply to employers in the Canary Islands?
Yes. This is national legislation, so the new deadline also applies to employers in Tenerife and elsewhere in the Canary Islands. Location does not alter the calculation of the six calendar days.
What may vary is each employer’s internal organisation: working patterns, administrative closures, authorised RED System users or coordination with an external adviser. The real workflow should therefore be reviewed instead of merely replacing “three” with “six” in a template.
Frequently asked questions about the new six-day deadline
Is the deadline now six business days?
No. It is six calendar days, so Saturdays, Sundays and public holidays are included.
Can I enter the date on which I submit the notification as the deregistration date?
Only if it is also the actual termination date. The extension affects the submission window, not the effective date that must be declared.
Has the deadline for registering a new employee also increased to six days?
Not under this reform. The change examined here concerns deregistration applications and data changes. Registrations continue to be governed by their own rules.
Must every employer report all CNO codes again?
Not necessarily. The six-month requirement concerns employees who are currently registered and whose occupation code has not yet been reported to the General Treasury of Social Security.
Will unsecured deferrals be automatic from 1 August?
No. The royal decree allows a later resolution to establish automated processing. That resolution and its terms must be published before the process can be treated as available.
What is the practical conclusion for employers?
The move from three to six calendar days gives employers a reasonable margin for reporting deregistrations and data changes, but it is no substitute for a sound employment-administration process. The actual date remains decisive, and the new window sits alongside other obligations that follow different rules.
