Labour payments
LFT Arts. 48–50, 76, 79–80, 84, 87, 89 and 162 (https://www.diputados.gob.mx/LeyesBiblio/pdf/LFT.pdf) govern the displayed components. Arts. 485–486 govern the seniority wage floor and cap. The 20-day option is limited to applicable indefinite-contract cases.
Separation tax
LISR Arts. 93 XIII–XIV, 95 and 96 (https://www.diputados.gob.mx/LeyesBiblio/pdf/LISR.pdf) distinguish exemptions, annual tax and withholding. This tool estimates withholding using the last ordinary monthly salary’s tariff rate, or the direct tariff when taxable separation is smaller. The 2026 tariff (https://www.sat.gob.mx/minisitio/NormatividadRMFyRGCE/documentos2026/rmf/anexos/Anexo-8-RMF-2026_DOF-28122025.pdf) supplies the current brackets.

Frequently asked questions
Does every dismissal include 20 days per year?
No. For indefinite employment this indemnity applies in the relevant LFT Arts. 49–50 cases, such as exemption from reinstatement, and justified separation by the worker under Art. 52. Unjustified dismissal alone does not automatically add it. Fixed-term contracts have different Art. 50 rules.
Is there a seniority premium on voluntary resignation?
For permanent workers, LFT Art. 162 requires at least 15 years on voluntary resignation. Dismissed workers receive it regardless of length of service. The estimate uses 12 days per year, with a wage floor of the zone minimum and a cap of twice that wage.
What salary is used for the three-month indemnity?
The integrated daily wage under LFT Arts. 84 and 89 includes proportional benefits. The estimate includes aguinaldo and vacation premium; you may enter a different integrated wage when other benefits apply. It does not apply the IMSS contribution ceiling to labour indemnity.
Which parts are tax exempt?
Aguinaldo and vacation premium have separate unused annual exemptions of 30 and 15 UMA. Separation payments share 90 UMA per service year. A fraction of more than six months counts as another tax year. Salary and vacation pay remain taxable; Art. 95 annual reconciliation is excluded.
