Payroll Management System in Java

Payroll Management System is a desktop application built with Java Swing and MySQL/MariaDB. It handles employee records, salary configuration, daily attendance, a live analytics dashboard, and automatic statutory pay slip generation — including EPF, ESI, Professional Tax, and slab-based Income Tax (TDS).

Key Features

• Secure login authentication with parameterized queries (SQL-injection safe)
• Live dashboard with KPI cards (total employees, monthly payroll cost, average net salary, today's attendance %), a gross-salary bar chart, and an attendance donut chart
• Employee management — add, update, delete, and list employees
• Salary management — configure HRA, DA, MED, PF, and Basic Salary
• Statutory payroll engine — automatic EPF, ESI, Professional Tax, and TDS deductions on every pay slip
• Attendance tracking (First Half / Second Half)
• Detailed pay slip generation with full earnings/deductions breakdown and net salary
• Print support for employee lists and attendance reports

Tech Stack

• Java (JDK 8+, tested on JDK 21)
• Java Swing (custom UI design system, Java2D vector icons — no image assets)
• MySQL / MariaDB (works with XAMPP)
• JDBC (MySQL Connector/J)

Statutory Deduction Logic

• EPF — taken from the salary record's PF field
• ESI — 0.75% of gross salary, applied only if gross ≤ ₹21,000/month
• Professional Tax — generic slab (₹0 under ₹10k, ₹150 for ₹10k–15k, ₹200 above ₹15k gross)
• Income Tax (TDS) — FY24-25 new-regime slabs on annualized gross minus ₹75,000 standard deduction
