What each takes, at three income levels
Each row is the same person in both countries: single, no children, no income beyond a salary, earning that multiple of their own country's average wage. That is why the gross figures differ between the two columns, and it is the only way two tax systems can be compared without pretending the wage levels are the same.

Why there is no common-currency figure here
Most comparison pages on this site convert both sides into one currency at the European Central Bank's published reference rate. This pair does not get that column, because the ECB does not publish a daily reference rate for CRC, and this site holds no other exchange rate it is willing to stand behind.
Reaching for a rate from an aggregator to fill the gap would put an uncited number in the middle of a page whose whole claim is that every figure carries its source. The rates and the local-currency amounts above are unaffected: they come from the OECD and are complete for both Costa Rica and Finland. It is only the conversion between them that is missing, and a comparison of shares of income does not need one.
What the employer pays on top
Neither figure above includes employer social security, which never reaches a payslip and is excluded from every take-home number on this site. It is published, and it changes what employing somebody actually costs: 24.6% of gross in Costa Rica against 20.5% in Finland. That is a gap of 4.2 percentage points, so the two countries look considerably closer from a payslip than they do from a payroll budget.
The rate on the next unit earned
Average rates decide what a year costs. Marginal rates decide whether a rise is worth taking, and the two do not always rank the same way. On the average wage the marginal rate is 9.8% in Costa Rica and 47.5% in Finland. Both measures point the same way in this pair, so the ranking is not sensitive to which one you use.
What this comparison leaves out
Everything except one household at three incomes. Not your salary, not a couple, not a parent, not residence rules, treaty relief or the timing of a move, and nothing at all about what the taxes buy in either place. The full account of what this series measures and what it cannot is on how these figures are published.
One side of this pair is computed on this site and the other is not. Costa Rica can take your own salary band by band; Finland reports published figures only, and its page says why.
Questions about Costa Rica and Finland tax
Do you pay more tax in Costa Rica or Finland?
Finland takes more. On the average wage a single person pays 30.7% in Finland against 9.8% in Costa Rica, a gap of 20.9 percentage points.
Which has the higher marginal tax rate, Costa Rica or Finland?
On the average wage the net personal marginal rate is 9.8% in Costa Rica and 47.5% in Finland. That is what is taken from the next unit earned rather than from the whole salary, so it is the figure that decides whether a rise or a bonus is worth taking, and it is not the same ranking as the average rate in every pair.
Where do these Costa Rica and Finland figures come from?
Both sides come from the same source: the OECD's Taxing Wages series for 2025, which publishes what a single person with no children actually pays at 67%, 100% and 167% of each country's own average wage. 44 rules sit behind this page, each carrying the dataset row it was read from and the date it was read, which was 06 September 2026. Because both halves come from one series, they cannot disagree with each other.
Does this tell me what I would pay if I moved?
No, and no comparison page can. These figures describe one household type at three income points in each country, in that country's own currency. They do not cover your salary, your household, residence rules, treaty relief, or the year you actually move. They are the right starting point and the wrong finishing point.
