13th month payDUE BY DEC 24

13th month pay is one twelfth of basic salary earned within the year. Allowances and overtime are not basic salary; months on leave without pay reduce the base.

The exemption ceiling applies to 13th month pay and other benefits combined. If bonuses already used part of the ₱90,000, the taxable excess here starts sooner.

Payroll Side

Where it lands in the books

The benefit flows through December payroll, into 1601C withholding when an excess is taxable, and into each employee's 2316. The withholding calculator handles the period tax.
