Largest corporate taxpayers in Siilinjärvi (2024)

The Finnish Tax Administration's public data lists 762 entities whose tax municipality is Siilinjärvi. 318 of them were assessed corporate income tax for tax year 2024, €14,918,859 in total. This page lists the 50 largest.

The ranking is by assessed corporate income tax, not by revenue or number of employees. Profitable entities therefore rank high. A large employer can be missing if its taxable profit was small or it made a loss. The municipality is the Tax Administration's tax municipality, the registered home municipality, not where the entity operates.

Methodology and sources

How was the tax year 2024 list built?

The Tax Administration publishes its public corporate income-tax data under Creative Commons Attribution 4.0. This compilation does not relicense the source data.

1. Tax Administration data
The source is the Tax Administration's public corporate income-tax data for tax year 2024, limited to entities whose tax municipality is Siilinjärvi (749). Later amendment assessments are applied once the Tax Administration has published them.
2. Order
Entities were sorted by assessed corporate income tax, and the 50 largest are published. Taxable income is shown in the table and does not change the order.
3. PRH join
Current name, main business line (TOL), company form, and situation flags come from PRH open data, joined by Business ID. The industry label is the Statistics Finland TOL 2025 division.
4. Publication
The page is a static compilation with no personal data. The tax year is read from the data, so the title and figures change when the list is rebuilt from the next tax year.

Limitations you should read

The ranking is by assessed corporate income tax, not by revenue or number of employees.
The tax municipality is the trade-register home municipality at the close of taxation. It does not show where sites or personnel are, and the municipal share of corporate tax is not allocated by it.
Housing companies, mutual real-estate companies, and limited-tax-liability estates are absent from the Tax Administration open data.
Name, industry, and situation flags are current PRH data, not the state during the tax year.
This page is not tax, investment, or credit advice.

Questions

Questions about corporate taxpayers in Siilinjärvi

Who is the largest corporate taxpayer in Siilinjärvi in 2024?

Why is a well-known Siilinjärvi company not on the list?

The ranking is by assessed corporate income tax, not by revenue or number of employees. A company is missing if its taxable profit for tax year 2024 was small or a loss, if its tax municipality is another municipality, or if the business is run by a group company registered elsewhere. Housing companies and mutual real-estate companies are not in the Tax Administration's open data.

What does assessed corporate income tax say about a company?

It is the tax confirmed in the assessment on the entity's taxable income. The Finnish corporate tax rate is 20 percent, so the figure mainly reflects taxable profit for the tax year. It does not show company size, headcount, or where the sites are.

When is the list updated?

The Tax Administration publishes public corporate income-tax data once a year in November. The list is rebuilt when the next tax year is public, and the tax year in the title changes with the data.
