If your company has employees or manages payroll for third parties, Royal Decree 643/2026 affects you as of today. The regulation, published on July 30, 2026, introduces specific changes in affiliation deadlines and contribution deferral rules that reduce administrative pressure on companies with high staff turnover and on management firms handling multiple clients.
The most visible change: you no longer have 3 days to report a worker deregistration or data variation, but 6 calendar days. It may seem like a minor detail, but for sectors with high turnover—hospitality, retail, logistics, construction—it eliminates a frequent source of incidents and surcharges.
What does this regulation establish?
Royal Decree 643/2026 modifies two key regulations: the General Regulation on company registration and affiliation (Royal Decree 84/1996) and the General Regulation on Social Security Collection (Royal Decree 1415/2004). The changes are grouped into four blocks:
| Matter | Previous situation | New regulation (RD 643/2026) |
|---|---|---|
| Deadline for reporting deregistrations and data variations | 3 calendar days | 6 calendar days |
| Contributions for work accidents and occupational diseases | Non-deferrable (with possible ambiguity depending on scheme) | Expressly non-deferrable for all schemes |
| Processing of deferrals without guarantees | Manual processing | Enables automated processing and granting |
| Limit of deferrable debt without guarantees | Twice the monthly minimum wage | Reduced limit, facilitating more approvals |
| Interest applicable to deferrals | Outdated regulation | Adapted to current regulations |
| Occupational code | No express transitional obligation | 6 months to report it for all active workers |
Regarding the occupational code: this data is crucial for workers in hazardous, toxic or dangerous jobs to access early retirement reduction coefficients. If the company does not report it, the worker may lose that right when their pension is recognized.
Economic and operational impact
The most immediate impact is the reduction of administrative incidents in affiliation management. With the 3-day deadline, any weekend or holiday turned a Friday deregistration into a real problem. With 6 calendar days, that risk disappears in most cases.
Regarding deferrals, the automation of granting without guarantees expedites cash flow for companies with occasional debts. The reduction of the deferrable debt limit without guarantees—which was previously twice the monthly minimum wage—may seem restrictive, but in practice it facilitates more requests being processed and resolved automatically, without manual intervention from the TGSS.
The clarification on contributions for work accidents and occupational diseases closes a deferral avenue that some companies used questionably. These contributions are non-deferrable in all schemes without exception, requiring more rigorous payment planning.
Who does it affect?
- Companies with high staff turnover: hospitality, retail, logistics, construction, agriculture. The new 6-day deadline reduces the risk of late communications.
- Management firms and labor advisors: manage multiple clients and accumulate deregistrations during peak periods. The extended deadline eases their daily operations.
- Companies with workers in hazardous or dangerous jobs: must report the occupational code in the next 6 months to avoid harming their employees' early retirement rights.
- Companies with occasional Social Security debts: benefit from automated processing of deferrals without guarantees.
- Self-employed employers: are also subject to the new deadlines for reporting deregistrations and variations.
- HR and administration departments: must update their internal procedures to reflect the new 6-day deadline.
Practical example
A hospitality company with 25 employees reports a worker deregistration on Friday, August 1, 2026. Under the previous regulation, it had until Monday, August 4 (3 calendar days) to process it, which in practice meant doing it that same Friday or over the weekend. With the new 6 calendar day deadline, the limit extends to Thursday, August 7, allowing it to be managed during normal business hours without risk of incident.
Additionally, if that same company has cooks or cleaning staff in positions classified as hazardous, it has until January 30, 2027 (6 months from entry into force) to report the occupational code for those workers. If it does not, those employees might not have the early retirement reduction coefficient recognized when they apply for their pension.
What should companies do now?
- Update internal affiliation procedures: replace the 3-day deadline with 6 calendar days in all protocols for reporting deregistrations and data variations to Social Security.
- Inform the HR team and management firm: ensure that those processing deregistrations know the new deadline to avoid unnecessary urgency.
- Identify workers in hazardous or dangerous jobs: review which job positions in the company may be subject to early retirement reduction coefficients.
- Report the occupational code before January 30, 2027: this is the 6-month deadline from entry into force. Failure to do so may harm the pension rights of affected workers.
- Review the contribution deferral policy: keep in mind that contributions for work accidents and occupational diseases are non-deferrable in all schemes, and plan cash flow accordingly.
- Consider automated processing of deferrals: if the company has occasional debts with the TGSS below the new limit, explore the automated route without guarantees to expedite resolution.

What is the occupational code and why must I report it?
The occupational code identifies the type of work performed by each employee.

How does automated processing of deferrals without guarantees work now?
Royal Decree 643/2026 enables automated processing and granting of contribution deferrals without the need to provide guarantees, for debts not exceeding the established limit (reduced from the previous two times the monthly minimum wage). This allows requests to be resolved without manual intervention from the TGSS, expediting the process for companies with occasional debts.
