INSS employee pension contribution (4%) is deducted before IPR and capped at BIF 18,000/month on the standard BIF 450,000 pension ceiling. Employer cost here includes the standard INSS pension branch (6% on BIF 450,000) plus the professional-risk branch (3% on BIF 80,000). Housing, transport, MFP and other payroll structuring rules are not modelled separately on this simplified cash-remuneration page.
