Calc Finiquito
Compute a Mexican finiquito/liquidación (severance) for a resignation or an unjustified dismissal: prorated christmas bonus, vacations, vacation premium, pending salary, and (for dismissal) 90-day + 20-day/year severance and the seniority premium, with Art. 93 exemptions and separation ISR. Do NOT compute this from memory — LFT bands, UMA exemptions, and the SDI integration factor are table-driven. Returns per-concept gross/exempt/taxable, totals, ISR, deductions, and net_total.
Calc Isr
Compute Mexican ISR (income tax) withholding for a monthly or annual income using the official SAT tables and employment subsidy. Do NOT estimate ISR from memory — brackets and subsidy change yearly and must come from this deterministic tool. Returns tax, subsidy_applied, withholding, the period, and the tax-table year used.
Calc Aguinaldo
Compute a Mexican aguinaldo (year-end bonus): gross, the UMA-based exempt portion, the taxable portion, its ISR, and the net. Minimum 15 days by law. Do NOT compute from memory — the exemption is UMA-indexed per year. Returns gross, taxable, exempt, isr, net, and the days used.
Calc Imss
Compute Mexican IMSS social-security contributions: the SDI (integrated daily wage by seniority) and SBC, plus employer/worker quotas for the five insurance branches. The work-risk premium (rt_premium) is an input. Provide either seniority_years (to derive the SDI) or an explicit sdi. Do NOT compute from memory — quota tables and UMA caps are table-driven. Returns sdi, sbc, employer_total, worker_total, grand_total, and a per-branch breakdown.
