Simple Payroll System with Dynamic Tax Bracket in PHP using SQLite Free Source Code

Introduction

This is a PHP Project entitled Simple Payroll System with Dynamic Tax Bracket. This simple application manages the company's employees' payroll. The system has a dynamic withholding tax bracket that can be managed by the admin user and this data are being fetched when calculating the employee's payslip/paycheck. The source code can help new programmers to understand how to develop a Payroll system.

• CSS
• JavaScript
• jQuery

About the Simple Payroll System with Dynamic Tax Bracket

This simple project can be only accessed by 2 types of users which are the administrator and staff. The admin can manage all the features and functionalities that the project does including the tax bracket while the staff users have only limited permissions. The system enlists/stores the company's departments, designations/positions, and employee lists.

Talking about the computation of payroll, the system can only handle Monthly and Semi-Monthly payroll in each employee. I used 22 working days a month for computing the daily rate and for counting the employee's days of absences. In generating the employees' paycheck, the system user can also add the employee's other earnings such as the allowances and deductions dynamically. For the other earnings, the system user can choose if the additional earnings are taxable or not. The system will get the latest tax data in the system.
