Introducing Importz: 400,000+ Official Car-Tax Decisions That Tell You What Importing to Finland Really Costs

Importz.fi is a free, open data service built on Finland's official car-tax decisions — 408,396 of them. Estimate your tax before you buy, browse real rulings, and find cars listed abroad with tax already calculated.

Buying a car in Finland is expensive, and everyone knows the workaround: import it from elsewhere in the EU. The part nobody tells you up front is the car tax — Finland taxes imported cars by value, CO2 emissions, and other factors, and the final bill is set by an official ruling after the fact. Brokers give you estimates with a margin baked in. What you actually want is to see the government's own numbers.

That's exactly what Importz publishes.

What it actually is

Importz is an open data service — not an import broker, and not a government site. It indexes Finland's official car-tax decisions (autoveropäätökset) from the Tax Administration and makes them searchable. The database currently holds 408,396 decisions across 296 brands, each traceable to its original source. The site states its own position plainly: an open data service for import tax values; no brokerage, not state-run, and free to use without registration.

How it works

The service has four parts that map to the actual import workflow:

  • Car tax calculator — pick a brand, model, year, and mileage; you get the median outcome and tax percentage from comparable real imports, not a guess.
  • Decision browser — filter the full official record by brand, model, year, and powertrain. Every entry links back to the original ruling, so you can cite it.
  • Findings — Importz continuously scans listings abroad (Swedish Blocket, among others) and republishes interesting cars with the estimated car tax already attached. A 2025 Porsche Cayenne Coupé with 22,500 km, a 2024 BMW M4 (estimated €125,665 all-in), a 2014 Maserati GranCabrio — the hunting is done for you.
  • Statistics — the most-imported brands, the biggest tax bills, and how powertrains are trending.

What the data says

The aggregate numbers are a decent argument for the service on their own:

  • Mercedes-Benz leads imports with 71,988 recorded decisions, followed by Volvo (60,267) and BMW (50,649).
  • 46,149 full-electric imports came in at €0 car tax — EVs enter Finland tax-free, which makes the import math very different for them.
  • The single largest recorded bill: €492,376 for a 2020 Lamborghini Aventador (566 kW, petrol).
  • Diesel is dying at the border — just 5% of recently imported passenger cars, down from a third a decade ago.

If you're deciding which car to import rather than whether, those trends are worth an afternoon of browsing on their own.

Who it's for — and who it isn't

Importz fits anyone in Finland weighing an EU import: before you bid on that German auction car or drive to Sweden, you can put a realistic tax number next to the asking price — using the same rulings the Tax Administration itself issues.

It is not:

  • An import service — no broker, no paperwork handling, no shipping. It tells you what a car will cost; getting it home is your job (or your broker's).
  • An official authority — the data mirrors public Tax Administration decisions, but rulings for your car are made by the authority, and estimates are estimates.
  • A guarantee — the median of past decisions is a strong signal, not a quote. Edge cases (modified cars, damage history) exist.

Our take

The honest-data position is the right one: import brokers monetize the information asymmetry around car tax, and a free, no-registration service that publishes the government's own rulings removes most of that asymmetry. The findings feed is the sleeper feature — cross-border deal-hunting with tax pre-calculated is genuinely useful even if you never import.

If there's a specific car on your wishlist and a Finnish price tag you don't like, an evening with the Importz calculator and decision browser is the cheapest due diligence you can do.
