Sources & scope. Core 2026 tax brackets and personal allowance are based on FPS Finance; employee social-security contribution uses the standard 13.07% rate. The July 2026 tax reform increased the income-year-2026 basic allowance; standard employee professional expenses use 30% capped at €6,070. Municipal surtax, social work bonus and special social contribution are circumstance-dependent, so they remain explicit user controls. This is a planning estimator, not a tax return, legal opinion, or official payroll slip. Individual circumstances, benefits, withholding rules and later legislation can change the final result.
