Income tax

Four brackets, and only the top slice is taxed higher

From 2026 Slovak personal income tax on employment (daň z príjmov zo závislej činnosti) is progressive across four bands. The consolidation package (zákon č. 261/2025 Z. z.) added the higher rates on top of the long-standing 19 %/25 % structure, so the scale now runs 19 % → 25 % → 30 % → 35 %. The point people most often get wrong is that the higher rates are marginal: each rate applies only to the slice of the base inside its band, never to the whole salary. Crossing a threshold never re-taxes the euros you already earned below it.

Because the calculator here is monthly, it works on the monthly bands — the employer withholds the advance (preddavok na daň) each month on one-twelfth of the annual thresholds. Those thresholds track multiples of the subsistence minimum (životné minimum), so the whole scale re-indexes each year with it.

The base is not the gross — it is the gross minus contributions

The number those bands are applied to is not your gross salary. First the employee’s insurance comes off, and what is left is the partial tax base (čiastkový základ dane) — the gross minus the 9,4 % social and 5 % health contributions you pay. So the contributions shrink the base before any rate touches it, and the tax is worked out on that smaller figure, not on the headline salary.

The tax-free allowance (nezdaniteľná časť)

Every taxpayer who signs the standard declaration can deduct a tax-free part of the base (nezdaniteľná časť základu dane na daňovníka). In the monthly payroll the employer applies a flat 497,23 € a month — 5 966,73 € over the year — subtracted from the partial tax base before the progressive rates apply. The monthly taxable wage is therefore the partial tax base minus this allowance, and only what remains is taxed.

For higher earners the allowance tapers — and 2026 tapers it faster than before. It stays at the full 5 966,73 € while the annual tax base is at or below 26 083,13 €; above that it is reduced by one-third of the base (the pre-2026 rule reduced it by a quarter), reaching zero once the annual base hits 43 983,32 €. That reduction is settled annually, in the year-end reconciliation (ročné zúčtovanie), not month by month — the monthly advance keeps applying the flat allowance, so a high earner’s monthly figure can look a little generous until the annual settlement squares it up. The calculator surfaces that as a note rather than trimming the monthly allowance, because that is what a payslip actually does.

The child tax bonus (daňový bonus na dieťa)

Families reduce their tax further with the child tax bonus. It is age-tiered: 100,00 € a month for a child under 15, and 50,00 € a month for a child from 15 to 18. From the age of 18 there is no bonus. The bonus is subtracted from the tax after the rates are applied — and it can go further than the tax itself.

Two limits gate it. First, a percentage cap on the partial tax base (§33 ods. 6): the bonus a household can claim cannot exceed a share of its partial tax base, and that share rises with the number of children — from 29 % for one child up to 64 % for six or more. Second, a high-income reduction (§33 ods. 10–11): once the monthly partial tax base passes 2 286,00 €, the bonus per child is trimmed by one-tenth of the excess. The exact monthly form of that high-income reduction is one we reconstructed from the statute’s annual wording, so we flag it as unconfirmed rather than presenting it as settled.

When the bonus turns into a payout

If the child bonus is larger than the tax left to pay, the difference is not lost and is not floored at zero — it is paid out to you. Your net pay can then exceed your gross minus contributions. This is why a low-to-middle earner with several young children can take home more than the raw “gross minus insurance” arithmetic suggests, and why the breakdown shows the paid-out portion as its own line.
