Methodology

The site is owned and run by Domino Invest OÜ (Estonian registry code 16571495, Harjumaa, Viimsi vald, Kibuvitsa tee 12). The same company is answerable for every figure shown and is named as the reviewing party in each calculator's structured data.

We are not a tax adviser or a financial institution. We sell no loans, insurance or investment products, and we hold no affiliate links or commission arrangements with any bank or insurer. Nothing on this site is for sale — which is why a calculation here can tell you something no bank would like.

Tax rates, thresholds and coefficients live in separate data files rather than inside calculation code. Each file names its source — the Tax and Customs Board, Riigi Teataja, Eesti Pank, the Social Insurance Board, the Transport Administration, the Health Insurance Fund — and the date it was last checked. That same date appears beside the result on the page and is machine-readable in the structured data.

For instance, the 2026 income tax rate of 22% and the €700 monthly basic exemption both come from one file, last verified on 2026-08-09. When a figure changes it changes in one place and reaches the calculator, the explanatory text and the structured data together — the page cannot contradict itself.

Unit conversions, geometry and arithmetic carry no source citation, because they have no source: a metre is a metre by definition. The verified mark is deliberately absent there — if it appeared everywhere it would mean nothing anywhere.

The change goes into the data file with a new verification date, and only once it exists in an official source — not when it has been reported in the news. A bill before parliament is not yet a rate.

When a new year's rate is not yet confirmed, the calculator does not quietly carry the previous year's forward. The page says plainly that the figure is unconfirmed and names the source we are waiting on. A wrong number that looks right is worse than an honest gap.

Some rates move mid-year. In 2026 the minimum wage rose on 1 April and the statutory late-payment rate on 1 July. In those cases a calculator has to know both periods — a single “2026 figure” would be wrong for a quarter of the year.

Behind every calculator is a pure function covered by an automated check against independently known answers — derived by hand or compared against an official calculator. The check runs before any change is published and refuses to pass a tax calculator that cites no official source.

The same check guards the app: the website and the mobile app run the identical calculation engine, so the two cannot disagree.

We do not give tax or financial advice. A calculator shows what the rules do with the numbers you enter; it knows nothing of your exemptions, agreements or prior-year balances. The official amount comes from the Tax and Customs Board, not from here.

We do not collect the numbers you enter. Calculations run on your own device, and the salary you type never leaves the browser. The privacy page sets that out in detail.

We do not pad pages to make them look longer. Where there is nothing substantial to say beside a calculator, there is no long text there either.

Tell us. A wrong figure is the most serious thing that can go wrong here, and we would rather hear it from you than from your next reader. The contact address is on the privacy page.
