How do you compute 13th month pay in the Philippines?

Omni HR computes 13th month pay automatically within the Philippine payroll module — calculating one-twelfth of each employee's total basic salary earned within the calendar year based on their salary history and employment period — and generates the required DOLE payroll report, with no manual formula needed. Under Philippine law, 13th month pay applies to all rank-and-file employees regardless of pay basis and must be paid on or before December 24.
