HRMantra : No. 1 In Payroll Software

Let’s face it. We all dread the idea of processing the payroll. 

It can be such a challenging task, especially when it comes to calculating payroll tax.

 What Is Payroll Tax? 

Payroll tax is not a single tax. It is a blanket term used to cover all types of taxes paid on the salaries of employees. 

When you hire an employee, you are responsible for deducting a portion of employee wages to pay a certain tax on their behalf. 

Depending on the nature of the employment, there are different taxes such as professional tax, TDS, provident fund, and more. 

It doesn’t end here. You also need to pay payroll taxes on each of your staff members from your revenue.

Unless you are aware of all types of taxes, you can get yourself in big trouble. Usually, companies who fail to deposit the tax amount or deposit the wrong amount have to bear heavy penalties from the government. 

This is the sole reason why most of the companies prefer to outsource their payroll process. 

In fact, the number of organizations who fully outsource their payroll functions has risen from 8% in 2015 to 12% in 2019. 

Fortunately, you will find many online payroll tax calculators designed to make your task easier.
