Social Security Compliance
Ensuring that the correct social security rules are applied to cross-border work.
On this page
In brief for employers
Social security compliance means that when working across borders, the social security system to which employees are subject is correctly determined, documented and monitored. It combines legal classification, payroll, evidence and ongoing monitoring.
Definition
When working abroad, it must be clarified whether employees will remain in the current social security system or will be subject to compulsory insurance in the country in which they work. A1 certificate, Certificate of Coverage, certificates according to social security agreements or special forms for multi-state employment may be relevant for this.
Typical cases
Social security compliance becomes relevant when:
- Posting
- business trip with work abroad
- home office abroad
- workation and remote work abroad
- Border commuters
- Multistate employment
- Work in countries with or without social security agreements
Typical Social Security Verification Questions
- Where does the person live and where does he or she actually work?
- In which countries do people work regularly?
- Are there multiple employers or self-employed activities?
- What duration, activity and role are planned?
- Does a social security agreement apply?
- Which form is required?
- Is HRMS, payroll and compliance data consistent?
A1, CoC, SVA and multi-state employment
| Theme | What it stands for |
|---|---|
| A1 certificate | Proof of applicable social security law in many European cases |
| Social security agreement / CoC | Framework and evidence for specific treaty states |
| Multistate employment | regular work in two or more states |
| ALPS and SV reporting portal | digital channels and processes for certain evidence |
Missing or incorrect evidence can lead to double contributions, gaps in coverage, questions during inspections and payroll corrections.

Frequently asked questions
When is social security compliance relevant for remote work?
As soon as employees from another country work or regularly cover several countries, it should be checked which social security system applies.
What is the difference between A1 and Certificate of Coverage?
A1 is the typical evidence in many European cases. A Certificate of Coverage is a comparable proof in certain bilateral agreement cases.
Why does HR need a social security verification process?
Because evidence can be missing before controls, travel or remote work phases if cases are only recognized manually or late.
