Simplified model: 2026 rates, social contributions by stage, health contribution by tax form (scale 9%, flat 4.9% with a deduction cap, lump-sum by annual thresholds). Capacity is indicative — the bank uses its own method.
Indicative, informational estimates — not tax, legal advice or an offer. Confirm your settlement with an accountant or tax adviser.
