Philippines reporting cycles and business-day rules
Philippine business-day cycles align with BIR monthly remittance schedules (Form 1601-C for compensation by the 10th, Form 0619-E for expanded withholding by the 10th) and BSP-administered PESONet (next-business-day) and InstaPay (real-time) clearing. SSS, PhilHealth, and Pag-IBIG contributions follow employer-ID-based cycles with deadlines from the 10th to the last day of the following month. Quarterly VAT (Form 2550Q) is due by the 25th of the month following each quarter-end. The 13th-month-pay legal deadline of December 24 under PD 851 is a hard payroll obligation.
