How it's calculated. The 2026 withholding tables for the three regions: Order (Despacho) No. 233-A/2026 of 6 January for mainland Portugal; Order No. 1179/2026 of 3 February for the Azores; and the 4th supplement to the Official Gazette of the Autonomous Region of Madeira, 2nd series, No. 13, of 20 January 2026, for Madeira. Table I applies to unmarried taxpayers without dependants and to married couples with two earners (€21.43 per dependant), Table II to unmarried taxpayers with dependants (€34.29), Table III to married couples with a single earner (€42.86), and Tables IV to VII to disability situations, adding €84.82 or €42.41 for each dependant with a disability rating of 60% or more. Each withholding amount is rounded down to the nearest euro, under Article 99-E of the CIRS. Overtime work is withheld at half the effective monthly rate. Social Security applies to the base salary, the taxable excess of the meal allowance, overtime work, and any subsidy twelfths actually paid that month, at the employee rates set out in the Social Security Contributions Code. Holiday and Christmas allowances are withheld separately, under Article 99-C: they are never added to the month's remuneration to determine the rate. IRS Jovem, under Article 12-B, uses the rate determined on the whole income but applies it only to the non-exempt portion, with the exemption on each payment capped at 55 × IAS divided by 14.
What's left out. Per diem allowances, bonuses, exempt income, part-time work with more than one employer, and the regime under Article 58-A of the Tax Benefits Statute (Estatuto dos Benefícios Fiscais). Withholding is a payment on account: the actual tax for the year is settled in the annual tax return, with the tax credits this simulator does not know about, and with the specific benefits that apply to disability situations.
