NČZD, the non-taxable part of the tax base, reduces taxable income. It is not a cash payment or a refund of the entire allowance. Establish income, contributions and the tax base before applying the allowance and calculating tax.

2026 amounts

The full annual personal allowance is €5,966.73 for a tax base up to €26,083.13. Above that, NČZD = €14,661.11 − tax base / 3, floored at zero. Monthly advances use €497.23. Compare the threshold with the tax base, rather than gross salary or turnover.

Why an annual shortfall can arise

Claiming the monthly allowance does not guarantee the same total annual entitlement. High pay, bonuses or multiple income sources can reduce the annual allowance. A €36,000 tax base gives €2,661.11 under the formula. This is an editorial example, not an individual payroll calculation.

How to claim

An employee signs a vyhlásenie with one employer. You can leave the allowance out of monthly payroll and claim the eligible amount in annual reconciliation or a tax return. This changes advances, not final tax. A sole trader claims it in the return; employment and business do not provide two personal allowances.

Other allowances and restrictions

The spouse allowance requires a shared household and circumstances specified in §11, such as care for a child of the relevant age, registered unemployment or disability. Having no income is not enough by itself. Assess the spouse’s own income and eligible months separately.

Eligible DDS/PEPP contributions can provide a separate deduction of up to €180 a year, subject to conditions. Personal NČZD applies to active income, not automatically to rental or investment income. Certain pensions received at the start of the year restrict entitlement.

Annual review checklist

Collect income certificates from every employer, other income details and evidence for additional allowances. Check whether employer reconciliation is available or a type B return is required. Income earned in 2026 is reconciled in 2027 using the forms for tax year 2026.

For 2026 employer reconciliation, submit the application and supporting documents by 15 February 2027; the employer completes it by 31 March. Business income or other circumstances requiring a return may make this route unavailable.

Worked calculation: how much does NČZD save?

Consider a person with one active income source and an annual tax base of €20,000 after compulsory contributions and allowable expenses. They are not a pensioner and have no other allowances or tax credits. After personal NČZD, the taxable amount is €20,000 − €5,966.73 = €14,033.27. Tax at 19% is €2,666.32. Without the allowance it would be €3,800: a saving of €1,133.68, not €5,966.73. The allowance itself must therefore not be added to an expected tax refund.

With an annual base of €36,000, the personal allowance is €14,661.11 − €36,000 / 3 = €2,661.11. This leaves €33,338.89; tax at 19% is €6,334.39. Incorrectly deducting the full €5,966.73 would produce €5,706.32. The €628.07 difference shows how much annual tax could be underestimated. This compares two annual calculations; the actual balance due depends on advances already withheld.

Why a high salary can look better during the year

Assume the employee’s monthly tax base after their contributions is €4,500 for each of 12 identical months, with no additional allowances or credits. The €54,000 annual base means zero personal NČZD. However, applying €497.23 monthly reduces withholding: in this example the whole deduction falls within the monthly 25% band, so the difference is approximately €124.31 a month, or €1,491.72 over 12 months. The benefit of that advance allowance disappears in the annual calculation. Rounding may change the result by a few cents.

For budgeting, ask payroll for the expected annual tax base instead of simply multiplying gross salary by 12. Include bonuses, another employer’s income and a business tax base. You can ask not to apply the personal allowance monthly; if entitlement remains at year end, it can be included in the annual calculation. Alternatively, set aside the estimated difference in a separate account each month. Forgoing the monthly allowance does not remove other possible causes of a tax balance due.

Working part of the year and multiple income sources

The annual personal NČZD is not divided by the number of months worked. For example, someone working only the final four months with a total active-income base of €8,000 can use €5,966.73: the balance is €2,033.27 and 19% tax is €386.32 under the assumptions above. Unused allowance is not paid out in cash. If employment and živnosť are combined, there is one allowance per person: employment income is reduced first, with any remaining allowance applied to the business base. Signing monthly declarations with two employers simultaneously risks an excessive allowance.

Spousal allowance: a separate example

Assume the taxpayer’s base is €30,000, the spouses share a household throughout the year, the spouse cares for a child of the qualifying age all year, and the spouse’s countable own income is €2,000. The spousal allowance is €5,455.30 − €2,000 = €3,455.30. If all the reduced base would be taxed at 19%, the tax reduction is €656.51. With only six qualifying months, the allowance is €1,727.65 and the tax reduction €328.25. Conditions must be met at the beginning of each qualifying month.

The spouse’s own income is not limited to salary: materské and nemocenské count, while rodičovský príspevok does not count as it is a state social benefit. If the claimant’s base exceeds €43,983.32, use a different formula: the greater of zero and €20,116.40 − one third of the base − the spouse’s countable income, then prorate for qualifying months. For example, a €48,000 base and €2,000 spouse’s income give a full-year allowance of €2,116.40. Zero spouse’s income without a statutory qualifying circumstance creates no entitlement.

Checks before signing the annual calculation

  1. Reconcile all annual income and withheld-contribution certificates; tax advances are a separate line.
  2. Check personal and spousal allowances separately, including evidence of the spouse’s income for the entire year.
  3. Check the child tax credit separately: it is a different mechanism excluded from these examples.
  4. Compare final tax with advances actually withheld. Only that difference shows the refund or balance due.
