Working across a border: what changes, and for whom

Current to September 11, 2026.

Work crosses borders as a matter of course now. The legal position on both sides of the arrangement rarely keeps pace with it.

A company engages someone who lives elsewhere. A professional takes a role with an employer in another country. These are ordinary decisions. Each one quietly changes an employment, tax and reporting position that nobody revisits until something forces the issue: an audit, a resignation, or the first careful reading of the agreement.

The exposure is real on both sides, but it is not the same exposure, and the two are often discovered at different times.

If you are the company

• Which country’s employment law governs the relationship, and how far it can be contracted out of
• Whether having a person working in another country creates a taxable presence for the business there
• Who must withhold, remit and report, and to which authority
• Whether statutory entitlements that were never budgeted for apply
• What termination looks like under rules nobody has read

Most of these are cheaper to answer before the first payment than after the first assessment.

If you are the professional

• Whether you are an employee or a contractor of the foreign entity, which is not always what the agreement calls you
• Where you are resident for tax purposes, and where your income is taxable — separate questions with separate answers
• Whether the employer is withholding and reporting correctly, and what falls to you if it is not
• What happens to social security and pension contributions when you pay into one country’s system while living under another’s

Two situations recur. The first is a professional who has been asked to invoice through a corporation, where the arrangement may attract personal services business treatment — see what a personal services business is. The second is a professional who assumes the employer has handled the filings, and finds out several years later that the obligation was theirs.

The structural choice

For the company, the options usually reduce to a few: engage the person as a contractor and carry the classification risk, establish an entity or branch, use an employer of record, or restructure the work so it is genuinely performed elsewhere. For the individual, the choice is narrower but the stakes are as high — accept the terms as offered, negotiate the ones that carry the exposure, or decline an arrangement that only works on paper.

In both directions the right answer depends on how long the arrangement is expected to last and how central the person is to the business.

Two bodies of law are always in play, and they answer different questions. Canadian law decides residency, withholding and reporting on this side, and what a Canadian employer owes. The other country’s law decides what it requires of a business operating into it and of a person working there. Neither answer substitutes for the other, and the same pair of questions arrives when work is moved south in response to tariffs. See employment.
