Basic Principles of Social Security
-
Social security is a public system of insurance and assistance through which the government guarantees income and care for vulnerable people who cannot support themselves, whether temporarily or permanently, due to factors such as old age, loss of a breadwinner, illness, disability, or unemployment.
-
Benefits can be monetary (sick pay, child allowance) or in-kind (personal care, medicine, equipment). Funding comes from collected social security contributions.
-
Social Security is recognized globally as a fundamental human right essential to societal order and quality of life.
-
Generally, social security is tied to the country where an individual works, though some systems base eligibility on residency as well.
-
Being subject to a country's social security system doesn't guarantee complete coverage. Protection levels depend on that country's specific schemes and individual eligibility requirements.
-
Most social security contributions are collected through payroll withholding. Unlike income tax issues, social security non-compliance is difficult to rectify retroactively, and employers bear full liability for contributions.
International Social Security Challenges
-
When individuals work and reside across multiple countries, jurisdictional conflicts can arise with multiple countries claiming authority over social security obligations.
-
Multi-jurisdictional situations create risks including benefit fragmentation, duplicate coverage and contributions, or conversely, coverage gaps and potential loss of entitlements.
-
To mitigate these risks, countries establish mutual agreements through treaties—both multilateral (e.g., EC Regulations) and bilateral ("Totalization Agreements"). These agreements aim to consolidate social security entitlements under a single system where possible through specific determination rules.
-
Despite social security often involving larger financial contributions than taxation, the network of social security treaties is less extensive than tax treaties.
Consequences of Social Security Non-compliance
There are 206 internationally recognized states worldwide with various forms of social security. Each country interprets and implements social security differently, creating a complex global landscape of coverage policies, requirements, procedures, and funding mechanisms that continues to grow more intricate.
In response to this increasingly complex international regulatory environment and heightened scrutiny from national authorities, companies have become more aware of the need to address social security implications in cross-border working arrangements, including short-term business trips.
This awareness is driven by the potentially excessive costs of social security that can significantly exceed employment tax costs due to uncapped insurance premiums and demographic factors leading to increased retirement contributions. These costs often surpass initial assignment estimates. Additionally, employees increasingly pressure employers to clarify how they will be protected against potential loss of social security benefits during international assignments and are more willing to pursue legal claims for lost benefit entitlements.
In summary, possible consequences of social security non-compliance:
For Employees:
-
Loss of social security benefit entitlements for employees and/or dependents
-
Denial of immigration clearance
-
Restricted or more expensive access to healthcare providers
For Employers:
-
Financial penalties and fines
-
Increased regulatory audits
-
Criminal charges against corporate stakeholders
-
Financial and reputational damage from employee litigation seeking compensation for lost benefits
-
Avoidable excessive social security costs
-
Project delays or termination due to immigration clearance issues.
While addressing social security compliance is clearly important, implementation challenges include:
-
Lack of ownership and central governance within organizations
-
Insufficient understanding of home and host country compliance requirements
-
Absence of appropriate social security compliance policies
-
Poor alignment between policies and processes
-
Inadequate cost management systems
-
Lack of real-time processes to update payroll systems when social security status changes
-
Inefficient processes for gathering compensation data from all involved countries.
