Concepts


Core concepts explain how salary, taxation, employment, and social systems are structured across countries.

They help interpret how income, costs, and contributions are defined and compared.


Residence vs Employment Location: Where You Live vs Where You Work

A person can live in one country and work in another, and this difference has important legal and financial consequences.

In practice, this means that taxes, social contributions, and employment rules are not always determined by a single country. Instead, they depend on how residence and employment location are defined within each system.

Understanding this distinction is essential for interpreting cross-border work situations and comparing systems.

What is residence

Residence refers to where a person lives on a regular or habitual basis.

In practice, this means that residence determines a person’s general legal connection to a country, especially for taxation and administrative purposes.

For a broader explanation of how residence affects taxation, see Which Country Has the Right to Tax Your Income?.

What is employment location

Employment location refers to where work is physically performed.

In practice, this means that employment location determines which country’s labour rules and social security system apply to the work itself.

For the legal framework that connects a worker and an employer, see How Work Is Legally Structured.

Relationship between the concepts

In practice, this means that different systems may apply at the same time, which can create overlaps or conflicts between rules.

Why the distinction matters

Residence and employment location are often assumed to be the same, but modern work arrangements frequently separate where a person lives from where work is performed.

In practice, understanding the distinction helps explain why tax, social-security and employment rules do not always originate from the same country.

A practical example

A person may live in one country and commute daily to work in another.

In practice, cross-border workers often need to consider both residence and employment location because each concept can affect a different part of the overall legal and financial framework.

For a related comparison between residence and a person's longer-term legal connection to a country, see residence vs domicile.

Use in law and systems

Differences across systems

These differences influence how cross-border work situations are handled, especially within coordinated systems such as the European Union.
