shallowdev.tinyapis/mx-fiscal · Verify this server
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.
