Finland: Foreign Key Employee Regime

Who it is designed for

Special-expertise employees; qualifying teachers/researchers

How the tax treatment works

25% final tax at source on qualifying wages from 2026. The exact tax result depends on your income mix, social-security position, deductions and whether every entry condition remains satisfied.

What to check before relying on it

• Must become a Finnish tax resident when starting qualifying work.
• Normally at least €5,800 monthly pay and work requiring special expertise.
• No Finnish tax residence during the five calendar years before the starting year.
• University teachers and qualifying scientific researchers have exceptions to salary/expertise conditions.

Where this regime can matter

The practical value of a special regime is the difference it creates over the period you expect to remain in the country. Compare the qualifying years with the ordinary tax system that applies before or after the relief, and separate employment income from investment, foreign-source and other income that may follow different rules. A strong headline rate can be less valuable if the route is short, difficult to maintain or does not cover the income that matters most to you.

Questions to answer before you rely on it

• Do I satisfy every prior-residence and arrival condition?
• Which parts of my remuneration are actually covered?
• Who must apply, and what is the deadline?
• What happens if I change employer, role or residence status?
• What tax and social-security rules apply when the special period ends?
