A payroll system involves everything that has to do with the payment of employees and the filing of ¬employment taxes. This includes keeping track of hours, calculating wages, withholding taxes and other deductions, printing and delivering checks and paying employment taxes to the government.

Payroll software often requires very little input from the employer. The employer is required to
inputemployee wage information and hours—then the software uses the information to perform
calculations and deduct withholdings automatically.

at the end in Java programming language. It will take input in form of Position, Monthly Salary,
AllowancesandOvertime Hoursworkedbythe employeeandthe deduction in wages will be based
on the marital statusof the employee. The deducted money will be in form of taxes, amount to be
funded for CSR(Corporate Social Responsibility) of the organization and amount provided to a
charity(social welfare)[(Note:- The deduction parameters used here are taken only for reference
purpose andthese may/maynotbe usedin real-world organizations)]. At the end, a payroll slip for
the employee will be generated based on our input and deductions. All of this will be done by
creating a project in Java.
