Uses official mainland 2026 withholding tables I–VII, including family/disability status, the one-percentage-point rate reduction for three or more dependants and whole-euro downward rounding. Holiday and Christmas subsidies are taxed separately from regular wages. The ordinary cash bonus is added to the payment month; select social coverage only if its contractual/regular nature makes it contributory. Employee social insurance is 11%; employer figure is ordinary 23.75% social insurance only. Single-earner married status requires the official sole/95%-earner test. Disability means certified incapacity of at least 60%; additional dependant multipliers must have been notified to payroll. This estimates payslip withholding, not final annual IRS or its refund: receipt deductions and municipal rebates are settled on the tax return. Excludes Madeira/Azores, IRS Jovem, IFICI/NHR, overtime, meal benefits, partial employment and employer contribution incentives.
