Deductions that reduce your gross pay
Income tax withholding (IRPF)
Progressive tax rate deducted at source based on annual earnings and family situation.
Social Security employee contribution
Mandatory deductions for general contingencies (4.70%), unemployment (1.55%-1.60%), and training (0.10%).
Personal and family status
Dependents, marital status and disability increase personal tax-free allowances, lowering withholding.
12 vs 14 installments
Annual net salary is identical, but monthly cash flow changes if extra paychecks are prorated across 12 months.
Flexible compensation
Pre-tax benefits like childcare vouchers, transport cards or health insurance lower taxable base and raise net take-home pay.
