Hiring someone overseas sounds straightforward until you realize every country runs its own rulebook, and none of them look like the one you know.
US companies expanding internationally face a layered set of obligations that go well beyond drafting an offer letter. Here are six legal requirements you need to understand before you make your first international hire.
Compliant Employment Contracts Written Under Local Law
Your standard US employment agreement won’t hold up in Germany, France, or Canada. Each country dictates by statute what a contract must contain; notice periods, trial clauses, and grounds for termination are legally required, not optional extras. When companies turn to EOR for hiring employees abroad for their first international hire, access to locally compliant contract templates is one of the primary draws. A contract that doesn’t align with local law isn’t just a compliance gap; it can render the entire employment relationship legally unenforceable, leaving the company genuinely exposed if the worker ever files a claim.
Some countries require bilingual contracts, and others mandate specific clauses covering intellectual property or non-competes in forms that differ sharply from US norms. Get local legal counsel to review every agreement before it’s signed.
Payroll Registration and Tax Withholding
You can’t run a foreign employee through your US payroll system. Most countries require employer registration with their national tax authority, correct local income tax withholding, and contributions to their social security or pension schemes. France, for example, has employer contribution rates that can add 40% or more on top of an employee’s gross salary, a cost that catches many US companies off guard the first time they model an international headcount budget.
Beyond registration, you’re responsible for accurate monthly or bi-monthly filings, year-end reconciliations, and maintaining payroll records in the format the local authority requires. Mistakes aren’t just fined; repeated non-compliance can result in your registration being revoked, which effectively prevents you from paying your own employee legally.
Statutory Benefits and Mandatory Leave
Statutory benefits in most countries aren’t perks; they’re floors set by law. Understanding what those floors are is a non-negotiable part of international hiring.
Common mandatory benefits include:
- Minimum paid annual leave (often 20 to 30 days, far above US norms)
- Statutory sick pay funded by the employer or the state
- Parental and maternity leave at legally specified rates
- Employer contributions to national healthcare or pension funds
- Severance calculations based on tenure, not at-will discretion
So if you hire someone in Spain and later terminate them without following the statutory severance formula, you’re exposed to a labor tribunal claim even if your contract says otherwise.
Work Authorization and Right-to-Work Verification
Every employee you hire abroad must hold the legal right to work in that country. It sounds obvious. But the verification process differs considerably by jurisdiction, and in the UK, right-to-work checks follow a defined government process with specific document categories; performing the check incorrectly strips you of any legal “excuse” defense if the worker later turns out to be unauthorized.
For employees you’re relocating from the US, visa and work permit requirements add another layer. Timelines can stretch to six months or longer in some markets, so any international hire involving relocation needs to kick off the immigration process well before the intended start date. Don’t assume a business visa covers employment; it almost never does.
Permanent Establishment Risk
This one catches US companies off guard more than almost anything else. If a foreign employee can negotiate or sign contracts on your company’s behalf, or if your company maintains a fixed place of business in another country - even informally - you may have created what’s known as a permanent establishment (PE). According to the EY Global Mobility Survey (2024), 72% of companies are already worried about PE exposure from remote and cross-border work arrangements.
A PE finding means the host country can tax your company’s profits tied to that presence. The liability can be retroactive, and penalties compound fast. To reduce PE risk, be explicit in employment agreements about what the employee is and isn’t authorized to do on your behalf, and bring in tax counsel in each market before the hire goes live.
Worker Classification Rules
The contractor-versus-employee distinction matters in every country, but each one draws the line differently. Brazil, Spain, and the UK all apply their own multi-factor tests to determine whether someone is genuinely self-employed or should be treated as an employee. Misclassifying an employee as an independent contractor isn’t just a tax problem; it can trigger back payments of benefits, social contributions, and statutory leave the worker was owed from day one.
But the stakes go beyond back pay. Several countries - including France and Australia - have introduced legislation specifically targeting gig-economy misclassification, with penalties directed at the company ordering the work, not just the one employing the worker. Before engaging anyone abroad on a contractor basis, have a local employment attorney assess the relationship against local classification rules.
Conclusion
The legal requirements for hiring employees in another country cover contracts, payroll, benefits, work authorization, PE risk, and worker classification, and each one carries real consequences if you get it wrong. The rules aren’t uniform, and they change. Working with local counsel in every market you hire into is the baseline; building those compliance checks into your international hiring process from the start is what keeps small expansions from turning into expensive problems.
