English translation prepared:
Mayak is an informational assistant, not an official service of Vero or any other public authority.
An estimated result
The calculator estimates take-home pay for one payment under the stated conditions. The result is not an official tax authority calculation, the final annual tax or a guarantee of the amount your employer will pay.
Mayak does not provide individual tax, legal, accounting or financial advice. This text explains the tool's limits and does not replace checking the accuracy of the calculation.
Tax card percentage
Mayak does not calculate your individual tax card percentage. You enter the basic percentage from an already issued, valid card. The calculator does not check your accumulated income or whether the income limit has been exceeded and does not determine the additional percentage.
Supported profile
The first version is intended for a limited ordinary-employee profile: a Finnish tax resident, a private employer, standard Finnish insurance, a valid salary tax card without exceeding its income limit, and one fully taxable cash payment for the whole month.
The age limits, minimum amount and exclusions are described in “Who this version is for”. Entrepreneurs, co-owners of their employer, international insurance exceptions, benefits in kind and additional deductions are outside the first model.
If a condition is unknown or a case is unsupported, no monetary result is provided. Such situations need separate verification; the absence of a result does not mean exemption from tax or contributions.
Year, version and rounding
The rules apply to 2026. Ruleset: fi-2026-tax-card-net-rules-v1; algorithm: fi-tax-card-net-half-up-v1.
HALF_UP for tax withholding is supported by a Vero rule. For TyEL and unemployment insurance contributions, it is a technical convention of Mayak algorithm v1, rather than a separately identified legal requirement.
Before making an important decision, check the year, applicability and current rules against the methodology and official sources. The rules for using the website are described in the Terms of Use.
