Finland was the first of the Nordic countries to end its treaty with Portugal, so a Finnish pension can be taxed in Finland and in Portugal at once, with only Portugal's own credit to soften the overlap. Finland also keeps a long reach over people who leave, through a three-year residency rule. The sections below take the missing treaty, the pension exposure, and the three-year rule in order. This is general guidance, not advice, and figures are date-sensitive and should be confirmed for your year.
Why Finnish Movers to Portugal Face a Specific Corridor
Most nationalities rely on a treaty to decide which country taxes their pension. Finns cannot, because Finland ended its convention with Portugal from 2019, the first of the Nordic terminations. Finland continues to tax Finnish-source pensions of people who have left, Portugal also taxes them as a resident, and the only relief is Portugal's unilateral credit for the Finnish tax.
Finland also does not let citizens leave cleanly: a three-year rule keeps a Finnish national presumed resident for a while after departure. And on the Portuguese side, IFICI does not exempt pensions. So the corridor is: understand that there is no treaty, plan the pension exposure, and clear the three-year rule on the way out.
Finland Was First to End Its Treaty with Portugal
Finland denounced its Finland-Portugal tax treaty, with termination taking effect from 1 January 2019, the earliest of the Nordic moves and ahead of Sweden's. The reason was the same pension dispute: the old treaty limited Finland's right to tax Finnish private pensions of Finns living in Portugal, which combined with Portugal's old NHR regime to leave those pensions barely taxed anywhere. A replacement treaty was signed in 2016 and ratified by Finland, but Portugal never brought it into force, so it does not apply.
With no treaty, neither country is bound by treaty allocation rules. Each applies its own law, and double taxation is managed only by each country's unilateral relief. In practice Portugal, as your country of residence, gives a credit for Finnish tax paid, while Finland gives no relief on Finnish-source income of a non-resident. Confirm that no replacement treaty has since entered into force before you rely on this.
Pensions: Taxed in Both Countries, Relieved Only by Credit
This is the heart of a Finnish move. Finland taxes Finnish-source pensions of non-residents, and, unlike some countries' flat non-resident tax, it taxes pensions progressively, broadly the way it taxes residents, with a tax card required to apply the right rate. Portugal then taxes the same pension as your country of residence, and because IFICI, the regime that replaced NHR, does not exempt foreign pensions, it is taxed at Portugal's ordinary progressive rates.
Without a treaty there is no cap and no clean allocation; what protects you from true double taxation is Portugal's unilateral credit for the Finnish tax, generally capped at the lower of the Portuguese tax on that income or the Finnish tax actually paid. The practical result is that you pay roughly the higher of the two effective rates, but the position is more exposed than for a nationality with a treaty, and a residual overlap can remain where the Finnish tax exceeds the Portuguese credit, so the pension is the central planning issue.
Ceasing Finnish Tax Residency: the Three-Year Rule
Finland does not treat a move as an immediate exit. Under the three-year rule, a Finnish citizen who leaves is presumed to remain a Finnish tax resident, taxed on worldwide income, for the year of departure and the three following years, unless you actively request non-resident status and show that you no longer keep essential ties to Finland.
What counts as an essential tie includes a permanent home still available in Finland, a spouse living there, continued Finnish social-security cover, or running a business in Finland; a summer cottage on its own does not. If you break the ties by the time you move, non-residency can apply from the departure date; if you break them later, it usually applies only from the next year. After the three years pass, the presumption flips in your favour. Selling rather than just renting the Finnish home, and documenting the broken ties, are the steps that make the exit clean.
Finnish Dividends, Interest, and Property
Without a treaty, the relief that usually reduces Finnish withholding is gone. Finnish dividends to a non-resident carry the full Finnish tax at source with no treaty reduction, and Portugal then taxes the dividend as your resident income with a unilateral credit. Finnish interest to a non-resident is generally not taxed in Finland, so it is usually taxed only in Portugal. Finnish real estate stays taxable in Finland because that is where the property sits, with Portugal taxing the same income and giving relief, and ordinary Finnish company shares are generally not taxed in Finland for a non-resident. The theme is constant: no treaty cap, so unilateral credit does the work.
Coordinating Vero and Finanças
Keeping Finnish pensions, shares, or property usually means Finnish filings as a non-resident alongside Portuguese filing, with no treaty and relief only by Portugal's credit for Finnish tax. The work is sequencing the move and the three-year rule, getting the Finnish tax card so the right rate is applied at source, tracking what Finland taxes so Portugal gives the credit for the right amount, and making both filings rely on the same facts. A signed Position Memo gives you and any Finnish adviser one position to file from.

Frequently Asked Questions
Is There a Tax Treaty Between Finland and Portugal?
No. Finland ended its treaty with Portugal from 2019, the first of the Nordic terminations, and no replacement has entered into force. Each country applies its own law and double taxation is relieved only unilaterally, mainly by Portugal giving a credit for Finnish tax. Confirm no replacement treaty has since entered into force.
How Is My Finnish Pension Taxed Once I Live in Portugal?
In both countries. Finland taxes Finnish-source pensions of non-residents, progressively rather than at a flat rate, and Portugal also taxes the pension as your country of residence at progressive rates because IFICI does not exempt pensions. Portugal gives a credit for the Finnish tax, so you pay roughly the higher of the two, but there is no treaty cap and a residual overlap can remain.
What Is the Three-Year Rule?
It is the Finnish rule that presumes a Finnish citizen who leaves remains a Finnish tax resident for the departure year and the three following years, unless they request non-resident status and prove they no longer keep essential ties to Finland, such as a permanent home or a spouse there. A summer cottage alone is not an essential tie. After three years the presumption flips in your favour.
Does IFICI Cover My Finnish Pension?
No. IFICI, the regime that replaced NHR, does not exempt pensions. A Finnish pension remains exposed to Finnish taxation and is also taxed by Portugal as your country of residence, with Portuguese credit relief. That overlap, and the absence of a treaty, makes the pension position the central planning issue.
Are My Finnish Dividends Taxed in Portugal?
Yes, and in Finland. Finnish dividends to a non-resident are taxed at source in Finland with no treaty reduction, and Portugal also taxes the dividend as your resident income, giving a unilateral credit for the Finnish tax. Finnish interest, by contrast, is generally not taxed in Finland and so is usually taxed only in Portugal.
