Finland Mobile ICT 2026 — Working in Finland with Another EU State's ICT Permit

1. First ICT or Mobile ICT?

First ICT is used for a direct transfer from outside the EU to a Finnish host entity. Mobile ICT becomes relevant where another EU Member State has already issued the applicant an ICT permit.

4. Short-term and long-term mobility differ

There are two ways of working in Finland on an ICT permit issued by another EU member state, and what each requires is entirely different. Under short-term mobility no separate Finnish residence permit is obtained: the first member state's permit suffices and Finland is only notified. Under long-term mobility a Finnish Mobile ICT permit has to be applied for.

Which side of the line you are on depends on how long the stay in Finland is and how it sits within the overall assignment from the first member state. That means the status can change if the plan lengthens: an assignment that began as short-term and is then extended outgrows the notification and needs a permit. Running that check the moment an extension is decided is how you avoid an argument about unauthorised work later.

5. Where responsibility sits: the sending or the host entity

On mobile ICT the employment relationship as a rule continues with the sending company outside the EU; the host entity in Finland does not become the employer. The working conditions, working time and safety rules applied in Finland nevertheless govern here, and the host entity is responsible for providing them. Which duty falls on which party should be written plainly into the assignment documentation.

The point missed most often in practice is social security. If the person remains in the sending country's system, the document evidencing that (an A1 within the EU) has to be held; without it an insurance obligation can arise in Finland. Taxation likewise turns on the length of the stay and where the pay comes from, and settling that before the assignment starts is cheaper than a double-taxation argument afterwards.

6. What the short-term mobility notification contains

The notification is not a shortened permit application; it is a separate document with a defined content. It should carry the person's identity details, the first member state and the permit's number and validity, details of the sending company and the host entity in Finland, the nature of the assignment and the dates of the stay in Finland. When it is made matters too: as a rule, before the assignment begins.

A notification not made does not by itself make the work unlawful, but it is a gap that has to be explained in an inspection and it concerns the host entity as well. If the dates change after the notification, it has to be updated; a difference between the dates notified and the time actually spent creates an inconsistency that is hard to explain afterwards. So making the notification once the assignment plan is settled is cleaner than filing early and correcting later.

7. Where family members stand on mobile ICT

Where family members live in the first member state on its permit, moving to Finland is not automatic for them. On long-term mobility, once the person holds a Finnish Mobile ICT permit, family members can apply to Finland through the family tie, and the permit granted is tied to the main applicant's period. On short-term mobility, moving the family to Finland is generally not intended and the existing arrangement stays in the first member state.

That distinction shapes the planning. If the assignment will run a year and the family is moving, school registration, healthcare and a spouse's right to work all have to be resolved separately on the Finnish side; none of them attaches automatically to the main applicant's permit. The scope of a spouse's right to work depends on the permit granted and should be checked in advance. Nor should the family's registration in the first member state be forgotten; records left open in two countries at once cause trouble later.

8. When the assignment ends: return, extension or a new permit

The logic of ICT rests on the person returning to the sending company at the end of the assignment. A mobile ICT permit is therefore not an open-ended route to settlement, and unlimited extension in the category should not be expected. When the assignment ends there are three routes: returning to the first member state or the country of origin, extending the existing permit as far as the law allows if the assignment lengthens, or moving to a work-based permit if the person is staying in Finland.

If the third route is chosen, timing decides. The new application has to be filed while the current permit is valid; otherwise the right to stay and to work falls into a gap. How time spent on ICT counts towards permanent residence should also be checked in advance, since permit types do not all carry the same weight in that calculation. The company has to decide early too: moving to a new permit can require the employment contract to move from the sending company to the Finnish entity, and that means separate arrangements for salary, social security and tax.

9. What documents a mobile ICT file contains

The core of the file is the ICT permit issued by the first member state itself, submitted so that its validity and the role it was granted for are visible. To that are added documents showing the sending company and the host entity belong to the same group: register extracts, the ownership structure and, where needed, a group chart. If the group relationship cannot be shown, the ICT logic does not hold up at all.

The second group of documents concerns the assignment: the assignment letter, the description of the role, its duration, the working conditions and who pays the remuneration. Evidence of qualification is also required in the manager or specialist categories; in the trainee category a training plan and a university degree come into play. The third group is personal: passport, identity documents and evidence of which country's social security applies. Building the file in these three parts from the start markedly reduces requests for clarification.

10. Common mistakes on mobile ICT

The commonest mistake is confusing first ICT with mobile ICT. Applying to Finland for a first ICT permit for someone already living in the EU on a valid ICT permit is a file opened in the wrong category, and it loses time. The second common mistake is failing to separate short-term from long-term mobility — applying for a permit where a notification would do, or notifying where a permit is required.

The third mistake is on the planning side: not allowing for the status changing when an assignment is extended. The fourth is the first member state's permit expiring during the assignment in Finland; because mobile ICT rests on that permit, its expiry removes the basis. The fifth is a missing social security document. Checking these five points once while the assignment is being planned makes almost all later corrections unnecessary.
