Managing payroll is one of the most time-consuming responsibilities of HR and finance teams — especially when it comes to computing the 13th month pay. Manual calculations often lead to delays, errors, and compliance issues.
Thankfully, modern HRIS (Human Resource Information Systems) now offer automated 13th month pay computation, allowing HR departments to generate reports instantly and with pinpoint accuracy.
In this article, we’ll explore how HRIS automates the 13th month pay, its key benefits, and best practices to ensure smooth and compliant payroll processing.
What Is 13th Month Pay?
The 13th month pay is a mandatory benefit in many countries (such as the Philippines) that provides employees with an additional month’s salary, typically released at the end of the year.
It’s calculated as:
13th Month Pay = Total Basic Salary Earned During the Year ÷ 12
While the computation looks simple, managing it for hundreds or thousands of employees can be challenging — especially when you factor in new hires, resignations, unpaid leaves, and prorated amounts.
This is where HRIS payroll automation becomes essential.
How HRIS Automates 13th Month Pay Computation
An HRIS payroll system automates the 13th month pay by pulling real-time data from your employee records, attendance, and salary components. Here’s how it works:
- Data Integration:
The HRIS consolidates all salary, attendance, and employment data into one platform. - Automated Calculation:
The system applies the proper formula based on the employee’s total earnings, automatically prorating for incomplete months or new hires. - Error-Free Validation:
Built-in compliance rules ensure that the 13th month pay is computed correctly according to labor regulations. - Instant Report Generation:
With just a few clicks, HR can generate detailed reports showing individual and company-wide 13th month pay summaries. - Approval and Disbursement:
Once validated, the system can forward the data to accounting for payment processing and official reporting.
